Abstract
Biliary tract complications are an important cause of morbidity and mortality after liver transplantation (LT) occurring in 5% to 25% of patients. The most common biliary complication in LT recipients are strictures representing approximately half of these biliary adverse events. Bile duct strictures can be divided into anastomotic biliary strictures (ABS) and non-anastomotic biliary strictures (NABS) depending on their location in the biliary tree, being ABS the most encountered type. Several risk factors identified in previous studies can predispose to the development of ABS and NABS, especially those related to surgical techniques and donor characteristics. Magnetic resonance cholangiopancreatography (MRCP) is the recommended noninvasive imaging test for detecting post-LT biliary strictures, given its high sensitivity and specificity. Once the diagnosis of a biliary stricture after LT has been made, endoscopic retrograde cholangiopancreatography (ERCP) is the preferred initial therapy with good short and long-term results. Biliary sphincterotomy plus balloon dilation (BD) with placement of multiple plastic stents (MPS) has been the classic endoscopic approach for treating ABS, although fully-covered metallic stents (FCSEMS) have emerged as an alternative thanks to shorter total duration of stenting and fewer endoscopic procedures compared to MPS. In this review, we provide a practical update on the management of biliary strictures after LT, focusing our attention on the available evidence in the endoscopic therapy.

Abstract
Importance Liver transplantation (LT) is a life-saving therapy for patients with end-stage liver disease and with acute liver failure, and it is associated with excellent outcomes and survival rates at 1 and 5 years. The incidence of biliary complications (BCs) after LT is reported to range from 5% to 20%, most of them occurring in the first three months, although they can occur also several years after transplantation. Objective The aim of this review is to summarize the available evidences on pathophysiology, risk factors, diagnosis and therapeutic management of BCs after LT. Evidence Review a literature review was performed of papers on this topic focusing on risk factors, classifications, diagnosis and treatment. Findings Principal risk factors include surgical techniques and donor's characteristics for biliary leakage and anastomotic biliary strictures and vascular alterations for non- anastomotic biliary strictures. MRCP is the gold standard both for intra- and extrahepatic BCs, while invasive cholangiography should be restricted for therapeutic uses or when MRCP is equivocal. About treatment, endoscopic techniques are the first line of treatment with success rates of 70-100%. The combined success rate of ERCP and PTBD overcome 90% of cases. Biliary leaks often resolve spontaneously, or with the positioning of a stent in ERCP for major bile leaks. Conclusions and Relevance BCs influence morbidity and mortality after LT, therefore further evidences are needed to identify novel possible risk factors, to understand if an immunological status that could lead to their development exists and to compare the effectiveness of innovative surgical and machine perfusion techniques.

Abstract
Background/Aims: Biliary strictures remain one of the most challenging aspects after living donor liver transplantation (LDLT). The aim of this study was to assess long-term outcome of endoscopic treatment of biliary strictures occurring after LDLT and to identify risk factors of recurrent biliary strictures following endoscopic retrograde biliary drainage (ERBD) in LDLT. Methods: A total of 1,106 patients underwent LDLT from May 1995 to May 2014. We compared the risk factors between patients with and without recurrent biliary strictures. Results: Biliary strictures developed in 24.0% of patients. Technical success rate of ERBD for biliary stricture after LDLT was 66.2% (145/219). Among 145 patients managed by endoscopic drainage, stricture resolution occurred in 69 with median duration of stent indwelling of 13.6 months (range, 0.5 to 67.3 months), and stricture recurrence was seen in 20 (21.3%) out of 94. The median recurrence-free duration after final endoscopic success was 13.1 months (range, 0.5 to 67.3 months). Older donor age (hazard ratio [HR], 1.10; 95% confidence interval [CI], 1.03 to 1.17; p=0.004) and non-B, non-C liver cirrhosis (HR, 5.10; 95% CI, 1.10 to 25.00; p=0.043) were associated with higher recurrence of biliary stricture. Conclusions: Long-term stricture resolution rate after ERBD insertion for biliary stricture occurring after LDLT was 73.4%. Clinicians should pay careful attention during following-up to decide when to remove ERBD in patients who have factors associated with recurrent biliary strictures.

Abstract
Biliary complications remain a common problem after liver transplantation (LT). The therapeutic endoscopist encounters a variety of situations in LT including strictures at the duct-to-duct biliary anastomosis, strictures elsewhere in the biliary tree caused by an ischemic injury, and bile leaks at the anastomosis or from the cut surface and stone disease. Biliary complications lead to significant morbidity and occasionally reduced graft and patient survival. Several factors increase the risk of strictures and leaks. Endoscopic intervention in experienced hands is successful in the management of biliary complications following LT and percutaneous or surgical correction should seldom be required.

Abstract
AIM: To investigate the diagnostic performance of multi-detector computed tomography (MDCT) in detecting biliary complications after orthotopic liver transplantation (OLT).
METHODS: Eighty-three consecutive OLT recipients, who presented with clinical or biochemical signs of biliary complications, underwent MDCT examination. Two experienced radiologists assessed MDCT images in consensus to determine biliary complications. Final confirmation was based on percutaneous transhepatic cholangiography or endoscopic retrograde cholangiography in 58 patients, surgery in four patients, liver biopsy in 10, and clinical and sonography follow-up in 11 patients.
RESULTS: Biliary complications were eventually confirmed in 62 of 83 patients (74.7%), including anastomotic biliary strictures in 32, nonanastomotic biliary strictures in 21, biliary stones in nine (5 with biliary strictures), anastomotic bile leak in five, and biloma in six (all with nonanastomotic strictures, and 2 with biligenic hepatic abscess). Twenty-one patients had no detection of biliary complications. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MDCT for detecting biliary strictures were 90.6%, 86.7%, 89.2%, 92.3% and 83.9%, respectively. For detecting biliary stones, anastomotic bile leak and biloma, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MDCT were all 100%.
CONCLUSION: MDCT is a useful screening tool for detecting biliary complications after OLT.

Abstract
Despite advances in patient and graft management, biliary complications (BC) still represent a challenge both in the early and delayed period after orthotopic liver transplantation (OLT). Because of unspecific clinical presentation, imaging is often mandatory in order to diagnose BC. Among imaging modalities, magnetic resonance cholangiography (MRC) has gained widespread acceptance as a tool to represent the reconstructed biliary tree noninvasively, using both the conventional technique (based on heavily T2-weighted sequences) and contrast-enhanced MRC (based on the acquisition of T1-weighted sequences after the administration of hepatobiliary contrast agents). On this basis, MRC is generally indicated to: (1) avoid unnecessary procedures of direct cholangiography in patients with a negative examination and/or identify alternative complications; and (2) provide a road map for interventional procedures or surgery. As illustrated in the review, MRC is accurate in the diagnosis of different types of biliary complications, including anastomotic strictures, non-anastomotic strictures, leakage and stones.

Abstract
The shortage of deceased donor liver grafts led to the use of living donor liver transplant (LDLT). Patients who undergo LDLT have a higher risk of complications than those who undergo deceased donor liver transplantation (LT). Interventional radiology has acquired a key role in every LT program by treating the majority of vascular and non-vascular post-transplant complications, improving graft and patient survival and avoiding, in the majority of cases, surgical revision and/or re-transplant. The aim of this paper is to review indications, diagnostic modalities, technical considerations, achievements and potential complications of interventional radiology procedures after LDLT.

Abstract
BACKGROUND Biliary complications are significant source of morbidity after liver transplantation (LT). Cholangiography is the gold standard for diagnosis and specification of biliary complications. OBJECTIVES Detailed analyses of ultrasound (US) as a safe imaging method in this regard are still lacking. Therefore we analyzed systematically the diagnostic value of US in these patients. PATIENTS AND METHODS Retrospectively, 128 liver graft recipients and their clinical data were analyzed. All patients had a standardized US examination. The findings of US were compared to cholangiographic results in 42 patients. Following statistical analyses were performed: descriptive statistics, sensitivity, specificity, positive and negative predictive values (PPV, NPV). RESULTS 42 patients had 54 different biliary complications (Anastomotic stenosis (AS) n = 33, ischemic type biliary lesions (ITBL) n = 18 and leakage n = 3). US detected n = 22/42 (52%) patients with biliary complications. The sensitivity, specificity, PPV and NPV of US were: 61%, 100%, 100%, 79% (95CI, 36-86%) for ITBL and 24%, 100, 100%, 31% (95CI, 9-46 %) for AS, respectively. CONCLUSIONS US examination had no false positive rate. Therefore, it may be helpful as a first screening modality. But for the direct diagnosis of the biliary complication US is not sensitive enough.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the first-line management in most situations when a benign biliary stricture is suspected. Although management principles are similar in all subgroups, the anticipated response rates, need for ancillary medical and endoscopic approaches, and use of less proven strategies vary between differing causes. Exclusion of malignancy should always be a focus of management. Newer endoscopic techniques such as endoscopic ultrasound, cholangioscopy, confocal endomicroscopy, and metal biliary stenting are increasingly complementing traditional ERCP techniques in achieving long-term sustained stricture resolution. Surgery remains a definitive management alternative when a prolonged trial of endoscopic therapy does not achieve treatment goals.

Degree of bile-duct dilatation in liver-transplanted patients with biliary stricture: a magnetic resonance cholangiography-based study. Radiol Med 2012; 117:1097-111. [PMID: 22438111 DOI: 10.1007/s11547-012-0805-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2011] [Accepted: 04/27/2011] [Indexed: 02/07/2023]
Abstract
PURPOSE This study assessed whether the degree of bile-duct dilatation in liver-transplanted patients is correlated with the time from intervention and the type of underlying biliary stricture. METHODS AND MATERIALS Fifty-seven 3D magnetic resonance cholangiograms (MRCs) performed on 42 liver-transplanted patients were retrospectively evaluated. Diameter was measured at the level of the extrahepatic bile duct (EBD), right hepatic duct (RHD), left hepatic duct (LHD), anterior and posterior right hepatic ducts (aRHD, pRHD) and left lateral and medial ducts (LLD, LMD). Data were stratified according to the type of biliary stricture (all types, anastomotic, ischaemic-like, mixed) and compared, on a per-examination basis: (a) between two groups based on time from transplantation using a 1-year threshold (nonlongitudinal analysis); (b) among 26 repeated examinations on 11 patients (longitudinal analysis); (c) among different stricture groups. RESULTS The biliary tree was slightly dilated within 1 year from transplantation (2.9±1.3 to 6.1±3.2 mm). In general, nonlongitudinal analysis showed minimally larger duct size after 1 year (mean +1.4±0.5 mm) despite significant differences at most sites of measurement considering all types of strictures (p<0.01; Mann-Whitney U test). Longitudinal analysis showed diameter increase over time, although without statistically significant differences (p>0.01; Kruskal-Wallis test). No significant difference in bile-duct size was observed when comparing types of stricture (p>0.01; Kruskal-Wallis test). CONCLUSIONS Biliary dilatation after liver transplantation is mild and develops slowly regardless of the underlying type of stricture, possibly in relation to graft properties. MRC has a potential role as first-line imaging modality for a reliable assessment of biliary dilatation and the presence of a stricture.

Abstract
PURPOSE To identify the diagnostic value of ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) in diagnosing biliary strictures after liver transplantation. MATERIALS AND METHODS Sixty patients with clinically suspected biliary strictures after liver transplantation were retrospectively evaluated. All patients underwent US and MRCP before the standard of reference (SOR) procedure: endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography. Radiological images were analyzed for biliary dilatation and strictures. RESULTS By SOR, biliary dilatation was present in 55 patients, stricture in 53 (44 anastomotic, 4 intrahepatic, 5 both), and dilatation and/or stricture in 58. Dilatation was diagnosed by US and MRCP in 39 and 45, respectively (sensitivity 71% vs. 82%, p=0.18). Stricture was diagnosed by US and MRCP in 0 and 42, respectively (sensitivity 0% vs. 79%, p<0.0001). False positive stricture was diagnosed by MRCP in 2. Dilatation and/or stricture was diagnosed by US in 39 and MRCP in 50 (sensitivity 67% vs. 86%, p=0.01); however, using both techniques, sensitivity increased to 95%. CONCLUSIONS MRCP is superior to US for diagnosing biliary strictures after liver transplantation primarily because MRCP can detect stricture. The combination of US and MRCP seems superior to either method alone. Our data suggest that in patients with normal US and MRCP, direct cholangiography could be avoided.

Abstract
PURPOSE This study was performed to assess the role of magnetic resonance cholangiography (MRC) in the clinical decision-making process of referring physicians when managing liver-transplanted patients. MATERIALS AND METHODS Over a 6-month period, 21 liver-transplanted patients with a suspected biliary complication were referred for MRC. Referring physicians were asked to prospectively state, before and after MRC, the leading diagnosis; the level of confidence (on a 0-100% scale); the most appropriate diagnostic/therapeutic plan. Data analysis assessed was the diagnostic yield of MRC; the proportion of change in the leading diagnosis; the therapeutic efficacy (i.e. proportion of change in the initial diagnostic/therapeutic plan); the diagnostic thinking efficacy (i.e., gain in diagnostic confidence). Statistical significance was assessed with the Mann-Whitney U test. MRC accuracy was also calculated. RESULTS Data analysis showed a diagnostic yield of 85.7%; a proportion of change in leading diagnosis of 19.0%; a therapeutic efficacy of 42.8%; a diagnostic thinking efficacy for concordant and discordant leading diagnoses of 18.8% and 78.7%, respectively (p<0.01). MRC accuracy was 92.3%. CONCLUSIONS MRC significantly increased the diagnostic confidence, irrespective of the concordance between pre- and posttest diagnoses. Moreover, MRC determined a change in patient management in a significant proportion of cases, leading to clinical benefits.

Abstract
Biliary strictures are one of the most common complications following liver transplantation, representing an important cause of morbidity and mortality in transplant recipients. The reported incidence of biliary stricture is 5% to 15% following deceased donor liver transplantations and 28% to 32% following living donor liver transplantations. Bile duct strictures following liver transplantation are easily and conveniently classified as anastomotic strictures (AS) or non-anastomotic strictures (NAS). NAS are characterized by a far less favorable response to endoscopic management, higher recurrence rates, graft loss and the need for retransplantation. Current endoscopic strategies to correct biliary strictures following liver transplantation include repeated balloon dilatations and the placement of multiple side-by-side plastic stents. Endoscopic balloon dilatation with stent placement is successful in the majority of AS patients. In patients for whom gaining biliary access is technically difficult, a combined endoscopic and percutaneous/surgical approach proves quite useful. Future directions, including novel endoscopic retrograde cholangiopancreatography techniques, advanced endoscopy, and improved stents could allow for a decreased number of interventions, increased intervals before retreatment, and decreased reliance on percutaneous and surgical modalities. The aim of this review is to detail the present status of endoscopy in the diagnosis, treatment, outcome, and future directions of biliary strictures related to orthotopic liver transplantation from the viewpoint of a clinical gastroenterologists.

Abstract
AIM To evaluate the dual-graft living donor liver transplantation (LDLT) with ultrasonography, with special emphasis on the postoperative complications. METHODS From January 2002 to August 2007, 110 adult-to-adult LDLTs were performed in West China Hospital of Sichuan University. Among them, dual-graft implantations were performed in six patients. Sonographic findings of the patients were retrospectively reviewed. RESULTS All the six recipients survived the dual-graft adult-to-adult LDLT surgery. All had pleural effusion. Four patients had episodes of postoperative abdominal complications, including fluid collection between the grafts in three patients, intrahepatic biliary dilatation in two, hepatofugal portal flow of the left lobe in two, and atrophy of the left lobe in one. CONCLUSION Although dual-graft LDLT takes more efforts and is technically complicated, it is safely feasible. Postoperative sonographic monitoring of the recipient is important.

Abstract
PURPOSE This paper discusses the role of colour Doppler ultrasound (CDUS) in the midterm follow-up of patients after orthotopic liver transplantation (OLT). MATERIALS AND METHODS We retrospectively studied 134 patients--102 men and 32 women, age range 21-68 years--who underwent liver transplantation between May 2006 and April 2007. In the first week after OLT, CDUS examination was performed daily in patients with anastomoses at a high risk of thrombosis, and on the basis of clinical and laboratory findings in other patients. After discharge, follow-up was performed 1, 3, 6 and 12 months after transplantation. Any new parenchymal focal lesion was studied by computed tomography (CT) and, where needed, biopsy. RESULTS CDUS identified the following complications: 22 biliary (B), nine vascular (V) and seven focal lesions (FL). Sensitivity, specificity, positive and negative predictive values and diagnostic accuracy were, respectively: 79.2%, 97.3%, 86.3%, 95.5%, 94% (B), 100%, 99.2%, 88.9%, 100%, 99.3% (V) and 100%, 96.9%, 42.8%, 100%, 97% (FL). CDUS also showed 16 blood collections and eight suspected biliary collections (four of which were confirmed by percutaneous puncture). CONCLUSIONS CDUS is an essential diagnostic tool in the follow-up of OLT. An early diagnosis of complications can improve graft integrity and patient survival.

Abstract
OBJECTIVES To validate trained community health workers' recognition of signs and symptoms of newborn illnesses and classification of illnesses using a clinical algorithm during routine home visits in rural Bangladesh. METHODS Between August 2005 and May 2006, 288 newborns were assessed independently by a community health worker and a study physician. Based on a 20-sign algorithm, sick neonates were classified as having very severe disease, possible very severe disease or no disease. The physician's assessment was considered as the gold standard. RESULTS Community health workers correctly classified very severe disease in newborns with a sensitivity of 91%, specificity of 95% and kappa value of 0.85 (P < 0.001). Community health workers' recognition showed a sensitivity of more than 60% and a specificity of 97-100% for almost all signs and symptoms. CONCLUSION Community health workers with minimal training can use a diagnostic algorithm to identify severely ill newborns with high validity.

Abstract
After liver transplantation, the prevalence of complications related to the biliary system is 6-35%. In recent years, the diagnosis and treatment of biliary problems has changed markedly. The two standard methods of biliary reconstruction in liver transplant recipients are the duct-to-duct choledochocholedochostomy and the Roux-en-Y-hepaticojejunostomy. Biliary leakage occurs in approximately 5-7% of transplant cases. Leakage from the site of anastomosis, the T-tube exit site and donor or recipient remnant cystic duct is well described. Symptomatic bile leakage should be treated by stenting of the duct by endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography (PTCD). Biliary strictures can occur at the site of the anastomosis (anastomotic stricture; AS) or at other locations in the biliary tree (non-anastomotic strictures; NAS). AS occur in 5-10% of cases and are due to fibrotic healing. Treatment by ERCP or PTCD with dilatation and progressive stenting is successful in the majority of cases. NAS can occur in the context of a hepatic artery thrombosis, or with an open hepatic artery (ischaemic type biliary lesions or ITBL). The incidence is 5-10%. NAS has been associated with various types of injury, e.g. macrovascular, microvascular, immunological and cytotoxic injury by bile salts. Treatment can be attempted with multiple sessions of dilatation and stenting of stenotic areas by ERCP or PTCD. In cases of localized diseased and good graft function, biliary reconstructive surgery is useful. However, a significant number of patients will need a re-transplant. When biliary strictures or ischaemia of the graft are present, stones, casts and sludge can develop.

Abstract
Orthotopic liver transplantation is a widely accepted treatment for end-stage liver disease and selected cases of hepatocellular carcinoma. Despite surgical progresses, biliary complications after transplantation remain a serious cause of morbidity, mortality, and graft dysfunction or failure in recipients. Early complications occur within a few weeks after transplantation and are mainly represented by bile leakage. Late complications, which become evident from 3 months to years, include strictures, stones, intraductal debris or sludge formation, kinking and ampullary dysfunction. Donor-to-recipient common bile duct disproportion has been reported as a borderline condition. Diagnosis is challenging because of the low specificity of clinical and biologic findings. Sonography does not provide projectional images of the biliary tract or direct evaluation of the anastomoses. Moreover, direct cholangiographic procedures have an unacceptable rate of complications to be used in patients with low clinical suspicion. Magnetic resonance cholangiography is a safe and accurate tool, playing an increasing role in the diagnosis and management of biliary complications. Heavily T2-weighted images provide panoramic, detailed evaluation of the biliary tract, showing biliary complications as a variable combination of bile duct dilatation, strictures, filling defects, fluid collections and peculiar morphologic changes, as described in this paper.

Abstract
Biliary complications are still the major source of morbidity for liver transplant recipients. The reported incidence of biliary strictures is 5%-15% after deceased donor liver transplantation and 28%-32% after right-lobe live donor surgery. Presentation is usually within the first year, but the incidence is known to increase with longer follow-up. The anastomotic variant is due to technical factors, whereas the nonanastomotic form is due to immunological and ischemic events, which later may lead to graft loss. Endoscopic management of anastomotic strictures achieves a success rate of 70%-100%; it drops to 50%-75% for nonanastomotic strictures with a higher recurrence rate. Results of endoscopic maneuvers are disappointing for biliary strictures after live donor liver transplantation, and the success rate is 60%-75% for anastomotic strictures and 25%-33% for the nonanastomotic variant. Preventive strategies in the cadaveric donor include the standardization of the type of anastomosis and maintenance of a vascularized ductal stump. In right-lobe live donor livers, donor liver duct harvesting also involves a major risk. The concept of high hilar intrahepatic Glissonian dissection, dissecting the artery and the duct as one unit, use of microsurgical techniques for smaller ducts, use of ductoplasty, and flexibility in the performance of double ductal anastomosis are the critical components of the preventive strategies in the recipient. In the case of live donors, judicious use of intraoperative cholangiograms, minimal dissection of the hilar plate, and perpendicular transection of the duct constitute the underlying principals for obtaining a vascularized duct.

Abstract
Biliary complications are a major cause of morbidity following orthotopic liver transplantation with an overall incidence between 11% and 25%. The most common complications are biliary leaks, strictures, and stones. These complications have an impact on graft survival, length of hospital stay, recovery, and overall cost of care. Therefore, knowledge of these complications and their management is important to the practicing gastroenterologist. Historically, biliary complications after liver transplantation have been managed surgically. However, with the growth of therapeutic endoscopic and percutaneous radiologic methods, most of these complications can now be managed less invasively. This article focuses on the incidence, timing, mechanism, and endoscopic management of biliary leak, strictures, stones, sludge, casts, and sphincter of Oddi dysfunction following liver transplantation.

Abstract
AIM: To assess the changes of portal and arterial velocities, resistance index, spleen and liver size during a long observation period (13.7 years) after orthotopic liver transplantation (OLT).
METHODS: Two hundred and sixty patients were recruited retrospectively for this study and divided into groups with defined time intervals after OLT. The cross-sectional changes of portal and arterial velocities, resistance index, spleen and liver size between the defined time intervals were studied. The complications detected by ultrasound were compared to gold standard methods.
RESULTS: The mean values for liver size were all within the normal range. The splenic size decreased between the time intervals 100 and 1 000 d after OLT (t; P<0.01). While portal and arterial flow velocities decreased up to 5.5 years (t; portal velocity P<0.01, maximal systolic velocity P = 0.05, maximal end diastolic velocity P<0.01), RI increased during this interval (t: P<0.01). Higher RI values were found in older patients (r = 0.24, P<0.001).
CONCLUSION: The arterial and portal velocities show adaptation processes continuing over the course of many years after OLT and are reported for the first time. The vascular complications detected by ultrasound occur mostly up to 100 d after OLT.

Abstract
AIM: To evaluate the diagnostic value of different indirect methods like biochemical parameters, ultrasound (US) analysis, CT-scan and MRI/MRCP in comparison with endoscopic retrograde cholangiography (ERC), for diagnosis of biliary complications after liver transplantation.
METHODS: In 75 patients after liver transplantation, who received ERC due to suspected biliary complications, the result of the cholangiography was compared to the results of indirect imaging methods performed prior to ERC. The cholangiography showed no biliary stenosis (NoST) in 25 patients, AST in 27 and ITBL in 23 patients.
RESULTS: Biliary congestion as a result of AST was detected with a sensitivity of 68.4% in US analysis (specificity 91%), of 71% in MRI (specificity 25%) and of 40% in CT (specificity 57.1%). In ITBL, biliary congestion was detected with a sensitivity of 58.8% in the US, 88.9% in MRI and of 83.3% in CT. However, as anastomotic or ischemic stenoses were the underlying cause of biliary congestion, the sensitivity of detection was very low. In MRI detected the dominant stenosis at a correct localization in 22% and CT in 10%, while US failed completely. The biochemical parameters, showed no significant difference in bilirubin (median 5.7; 4,1; 2.5 mg/dL), alkaline phosp-hatase (median 360; 339; 527 U/L) or gamma glutamyl transferase (median 277; 220; 239 U/L) levels between NoST, AST and ITBL.
CONCLUSION: Our data confirm that indirect imaging methods to date cannot replace direct cholangiography for diagnosis of post transplant biliary stenoses. However MRI may have the potential to complement or precede imaging by cholangiography. Optimized MRCP-processing might further improve the diagnostic impact of this method.

Abstract
BACKGROUND AND AIM The biliary tract has been referred to as the "Achilles heel" of liver transplantation. The aim of this study was to document the frequency, clinical presentation and management of biliary complications after liver transplantation in the King Faisal Specialist Hospital and Research Center (KFSH&RC), Riyadh, Saudi Arabia. METHODS The liver transplant clinic at KFSH&RC has registered and followed 220 patients (150 male and 70 female patients; age 40.6 +/- 18.6 years; pediatric 33, adult 187) during the period from 1987 to June 2003. A total of 235 transplants were carried out on these patients. Cadaveric liver transplants had been carried out on 202 patients, non-heart beating liver transplant in three patients, live donor liver transplants in 11 and split transplant in four. Biliary reconstruction was duct-to-duct anastomosis in 147 patients and Roux-en-Y in 73. Biliary complications were suspected on clinical and biochemical parameters and confirmed using imaging techniques. RESULTS Forty patients (18.2%) developed 53 biliary complications. These included bile leak in 16, strictures in 25, calculi in eight, and sphincter of Oddi dysfunction and possible recurrence of primary sclerosing cholangitis in the donor duct in two patients each. Bile leaks were observed in the early postoperative period (median period 30 days, range 1-150 days, 95% confidence interval [CI] 8-51). Leakage occurred at the anastomotic site in 13 patients. Patients presented with bilious drainage (n = 6), abdominal pain at T-tube removal (n = 3), fever (n = 2), sepsis (n = 1), dyspnea (n = 1) and abnormal liver tests (n = 3). Eleven patients had intra-abdominal bilious collections. Two patients were treated conservatively, eight patients had ultrasound-guided aspiration of biloma, five had biliary stenting at endoscopic retrograde cholangiopancreatography and two patients needed surgery. There were four deaths, two of which were related to bile leak, one patient was left with permanent external biliary drainage and four patients had biliary strictures in the follow-up period. Biliary strictures occurred at a median period of 360 days (range 4-2900 days; 95% CI 50-670) after the transplant. Hepatic artery thrombosis caused biliary strictures in three, while 21 strictures were localized to the anastomotic site. Biliary strictures presented with elevated liver tests in five patients, progressive cholestasis in five, cholangitis (with septicemia in five) in 11, abdominal pain in two and acute pancreatitis in three patients. Repeat sessions of endoscopic or percutaneous dilatation and stenting (mean sessions 4.4/patient, range 3-7) were attempted in 20 patients to relieve strictures, with success in only nine patients. Seven patients had surgery. Four patients with biliary strictures died. Biliary calculi developed late in the follow-up period and had the appearance of biliary casts in five and sludge in three patients. Eleven (27.5%) patients with biliary disease died compared with 35 (19.4%) patients without biliary disease. CONCLUSIONS Biliary complications occurred in 18.2% of patients after liver transplantation and included biliary leak and biliary strictures with or without calculi. Management involved a combination of endoscopic, radiologic and operative procedures. Biliary complications caused considerable morbidity and mortality in liver transplant patients.

Abstract
The goal of this study was to evaluate the significance of biliary dilatation proximal to the level of obstruction in liver transplant recipients with anastomotic strictures. A retrospective review of all liver transplants with duct-to-duct biliary reconstruction performed at our institution was conducted to identify patients with anastomotic stricture. Maximum diameter of the donor bile duct proximal to the stricture was measured from cholangiographic images taken at diagnosis and most recent follow-up. The change in duct size during this time was compared between those who responded to treatment (responder group) and those who did not (nonresponder group). Mean maximum duct diameter at diagnosis in the responder group was 10.1 mm at diagnosis and 12.1 mm at follow-up. This compared to a mean of 10.6 mm at diagnosis and 12.4 mm at follow-up in the nonresponder group. This corresponded to an average change in duct size between diagnosis and follow-up of +1.9 mm in the responders and +1.8 mm in the nonresponders. In posttransplant patients with obstructive cholestasis, duct dilatation does not correlate with clinically significant obstruction. Further, the change in duct size after treatment is not indicative of cholangiographic improvement.

Abstract
Liver transplant patients who present with abdominal pain after removal of the T-tube can be initially evaluated by contrast-enhanced magnetic resonance cholangiography (CEMRC) instead of abdominal computed tomography and hepatobiliary scintigraphy. In this article, 3 liver transplant patients who were evaluated by CEMRC after removal of the T-tube. CEMRC successfully identified the presence, location and extent of bile duct leaks, and can be performed as a diagnostic study in patients with suspected bile duct leaks.

Abstract
The goal of this study was to evaluate the significance of biliary dilatation proximal to the level of obstruction in liver transplant recipients with anastomotic strictures. A retrospective review of all liver transplants with duct-to-duct biliary reconstruction performed at our institution was conducted to identify patients with anastomotic stricture. Maximum diameter of the donor bile duct proximal to the stricture was measured from cholangiographic images taken at diagnosis and most recent follow-up. The change in duct size during this time was compared between those who responded to treatment (responder group) and those who did not (nonresponder group). Mean maximum duct diameter at diagnosis in the responder group was 10.1 mm at diagnosis and 12.1 mm at follow-up. This compared to a mean of 10.6 mm at diagnosis and 12.4 mm at follow-up in the nonresponder group. This corresponded to an average change in duct size between diagnosis and follow-up of +1.9 mm in the responders and +1.8 mm in the nonresponders. In posttransplant patients with obstructive cholestasis, duct dilatation does not correlate with clinically significant obstruction. Further, the change in duct size after treatment is not indicative of cholangiographic improvement.

Abstract
UNLABELLED Biliary complications following orthotopic liver transplantation (OLT) may be associated with significant morbidity and mortality. In this report, we reviewed our endoscopic experience of managing post OLT biliary complications in 79 patients over a 12-year period. METHODS OLT (n = 423) recipients between 10/86 and 12/98 were obtained from the transplant registry at the Johns Hopkins Hospital. OLT recipient who underwent at least one endoscopic retrograde cholangiography (ERC) were identified through a radiology database. Indications, findings and interventions performed were noted for each ERC report. Outpatient and inpatients medical records were reviewed for outcome and complications. RESULTS Seventy-nine (79/423, 18.7%) patients had at least one ERC for suspected biliary complication. Sixty-four (15.1%) patients had at least one or more biliary complications. The mean follow-up for patients with abnormal ERC was 33.9 months. Nineteen patients had bile leaks; 10 of these patients had leak at the exit site of the T-tube and five patients had at the anastomosis. Biliary stenting with or without endoscopic sphincterotomy led to resolution of bile leak in 16 patients. Three patients failed endoscopic therapy: one underwent surgery and two had percutaneous drainage. Twenty-five patients presented with biliary strictures. Nineteen strictures were at the anastomotic or just proximal to the anastomosis, one at the hilum (ischemic in nature) and three were at the distal, recipient common bile duct; one had strictures at the anastomosis as well as the distal recipient bile duct and another had diffuse intrahepatic strictures. Seventeen patients in the stricture group improved with endoscopic intervention. One patient was re-transplanted (diffuse intrahepatic strictures), but no patient underwent percutaneous drainage. CONCLUSIONS ERC is safe and effective in the diagnosis and management of biliary complications following liver transplantation with choledochocholedochal anastomosis and obviates the need for surgical or percutaneous transhepatic approaches in majority of cases.

Abstract
The possibilities and the limits of transabdominal ultrasonography (US) in the diagnosis of bilio-pancreatic diseases are reviewed here in the light of the last 10 years' research. US remains the method of choice for the diagnosis of gallstones and is generally accepted as an initial imaging technique in gallstone complications, such as acute cholecystitis. Moreover the method can be useful for the detection of the biliary complications after laparoscopic cholecystectomy and after liver transplantation. US is still considered the first diagnostic procedure when stones are suspected in the common bile duct. The use of color Doppler can provide a differential diagnosis of gallbladder cancer with respect to other benign inflammatory or polypoid lesions. Color Doppler US allows to detect vascular complications of acute pancreatitis such as pseudoaneurysms. US is still considered useful for the initial screening of the pancreatic cancer. However, for staging other imaging techniques must be employed. With US useful informations are obtained in the diagnosis of cystic tumors of the pancreas and of pancreatic metastases. US is generally of little use for the diagnosis of endocrine tumors.

Abstract
Hepatic transplantation has become the treatment of choice for advanced irreversible liver disease. More than 4,000 hepatic transplantations were performed in the United States in 1997 and more than 11,000 are awaiting transplantation. Graft endurance and overall patient survival has been steadily improving, and between 1992 and 1994, 82% of the patients who received a liver transplant survived for at least a year. Today, liver transplant patients have a five-year survival rate of approximately 75%. The improvement in survival can be attributed to better patient selection and preparation, advances in organ preservation, improved immunosuppressive therapy agents and refinement of surgical techniques. In this article, we will address the hepatic parenchyma and vascular structures that should be evaluated prior to and following liver transplantation, the range of expected anomalies and abnormalities, and the utility of each of the three main imaging modalities, namely ultrasonography, computed tomography and magnetic resonance imaging in this assessment.

Abstract
1. Biliary complications of some type occur in approximately one of every eight liver transplant recipients. Although they are uncommon causes of mortality, they are significant sources of morbidity. 2. Leaks and strictures that occur early after transplantation have technical causes. Late strictures and obstruction are more likely to be complex and have multiple causes, including hepatic artery occlusion, preservation injury, rejection, and recurrent disease. 3. Diagnosis relies on abdominal imaging and cholangiographic studies. Patency of the hepatic artery must be proven when a complication of the donor biliary tree occurs. 4. Management of late complications is largely influenced by the nature and extent of strictures. Percutaneous and endoscopic treatment of anastomotic strictures offers a significant prospect of successful long-term management. 5. Nonsurgical management of more complex hilar and intrahepatic strictures is less successful, and surgical revision or retransplantation may be required for definitive treatment.

Abstract
1. Lifelong monitoring of graft function, immunosuppressive levels, and screening for drug toxicity is required in all liver recipients. 2. Late hepatic allograft dysfunction is common and is caused by a variety of etiologies including rejection, infection, biliary/vascular abnormalities, recurrence of disease, and drug hepatotoxicity. 3. In all patients with late hepatic allograft dysfunction, liver biopsy should be performed to assess for the presence of rejection, and to thus avoid excessive use of bolus corticosteroid therapy and guide appropriate immunosuppressive management. 4. Recurrence of disease is the most common cause of late hepatic allograft dysfunction. 5. Hepatitis C universally reinfects the hepatic allograft, and is associated with decreased patient and graft survival and leads to the recurrence of cirrhosis in 28% of patients within 5 years of transplantation. 6. Major advances have been made in preventing recurrence of hepatitis B by the use of hepatitis B immune globulin in combination with lamivudine therapy. 7. Autoimmune liver diseases such as primary biliary cirrhosis, primary sclerosing cholangitis, and autoimmune hepatitis have a recurrence rate of approximately 20% to 30%. 8. In patients developing recurrence of autoimmune hepatitis, steroid withdrawal is the most common cause. 9. Recurrent hepatocellular cancer can be markedly reduced if strict guidelines are adhered to in selecting patients. 10. Drug hepatotoxicity must always be considered in the differential diagnosis of late hepatic allograft dysfunction.
