Core factors involved in the treatment of hemorrhoids include the engorgement of hemorrhoids, prolapse, recurrence, and pain.

The goal of this study was to assess the safety, pain, and efficacy of the transanal suture mucopexy for the treatment of hemorrhoids.

This was a retrospective study over a 13-year period.

This procedure was performed, and data collected, from medical records at six centers in India.

This study includes 5634 patients who had grade II to IV symptomatic hemorrhoids. Patients suffering from thrombosed hemorrhoids, inflammatory bowel disease, anal strictures, and anorectal carcinoma were excluded.

Hemorrhoidal swelling was reduced by manual massage and a steep Trendelenburg position under saddle block. The reduced hemorrhoids were fixed to the muscles of the rectal wall using sutures. Each suture measured 0.5 to 1.0 cm in length; double-locking continuous sutures were used, along the complete circumference of the rectum, at 2 and 4 cm proximal to the dentate line.

Pain assessed using the visual analog scale and hemorrhoid recurrence served as outcome measures.

The transanal suture mucopexy procedure was performed for 5634 patients with symptomatic hemorrhoids. A dull pain compatible with a visual analog score of 2 to 3 was reported in 126 (2.2%) patients; in the remaining 5508 (97.8%) patients, the visual analog score was 1 to 2. Effective treatment without complications occurred for 5541 patients (98.65%). A recurrence rate of 1.3% was recorded in 5634 cases with a mean follow-up of 7 ± 6 years.

Utilization of a self-illuminating proctoscope or Brinckerhoff or anal speculum is essential.

Transanal suture mucopexy, designed with 2 suture rows, is a safe procedure with a short learning curve. It is associated with minimal pain, low recurrence rate, and fewer complications. See Video Abstract at http://links.lww.com/DCR/B841.

Background and Objectives: Excisional hemorrhoidectomy is considered as a mainstay operation for high-grade hemorrhoids and complicated hemorrhoids. However, postoperative pain remains a challenging problem after hemorrhoidectomy. This systematic review aims to identify pharmacological and non-pharmacological interventions for reducing post-hemorrhoidectomy pain. Materials and Methods: The databases of Ovid MEDLINE, PubMed and EMBASE were systematically searched for randomized controlled trails (published in English language with full-text from 1981 to 30 September 2021) to include comparative studies examining post-hemorrhoidectomy pain as their primary outcomes between an intervention and another intervention (or a sham or placebo). Results: Some 157 studies were included in this review with additional information from 15 meta-analyses. Fundamentally, strategies to reduce post-hemorrhoidectomy pain were categorized into four groups: anesthetic methods, surgical techniques, intraoperative adjuncts, and postoperative interventions. In brief, local anesthesia-alone or combined with intravenous sedation was the most effective anesthetic method for excisional hemorrhoidectomy. Regarding surgical techniques, closed (Ferguson) hemorrhoidectomy performed with a vascular sealing device or an ultrasonic scalpel was recommended. Lateral internal anal sphincterotomy may be performed as a surgical adjunct to reduce post-hemorrhoidectomy pain, although it increased risks of anal incontinence. Chemical sphincterotomy (botulinum toxin, topical calcium channel blockers, and topical glyceryl trinitrate) was also efficacious in reducing postoperative pain. So were other topical agents such as anesthetic cream, 10% metronidazole ointment, and 10% sucralfate ointment. Postoperative administration of oral metronidazole, flavonoids, and laxatives was associated with a significant reduction in post-hemorrhoidectomy pain. Conclusions: This systematic review comprehensively covers evidence-based strategies to reduce pain after excisional hemorrhoidectomy. Areas for future research on this topic are also addressed at the end of this article.

Surgical treatment of hemorrhoids is still a dilemma. New techniques have been developed leading to a lower rate of postoperative pain; however, they are associated with a greater likelihood of recurrence.

To review current indications as well as the results and complications of the main techniques currently used in the surgical treatment of hemorrhoidal disease.

A systematic search of the published data on the options for treatment of hemorrhoids up to December 2012 was conducted using Medline/PubMed, Cochrane, and UpToDate.

Currently available surgical treatment options include procedure for prolapse and hemorrhoids (PPH), transanal hemorrhoidal dearterialization (THD), and conventional hemorrhoidectomy techniques. Excisional techniques showed similar results regarding pain, time to return to normal activities, and complication rates. PPH and THD were associated with less postoperative pain and lower complication rates; however, both had higher postoperative recurrence rates.

Conventional surgical techniques yield better long-term results. Despite good results in the immediate postoperative period, PPH and THD have not shown consistent long-term favorable results.

Hemorrhoids are common human afflictions known since the dawn of history. Surgical management of this condition has made tremendous progress from complex ligation and excision procedures in the past to simpler techniques that allow the patient to return to normal life within a short period. Newer techniques try to improve on the post-operative complications of older ones. The surgical options for the management of hemorrhoids today are many. Capturing all in a single article may be difficult if not impossible. The aim of this study therefore is to present in a concise form some of the common surgical options in current literature, highlighting some important post operative complications. Current literature is searched using MEDLINE, EMBASE and the Cochrane library. The conclusion is that even though there are many surgical options in the management of hemorrhoids today, most employ the ligature and excision technique with newer ones having reduced post operative pain and bleeding.

Hemorrhoid disease is the most common reason patients seek evaluation by a colon and rectal surgeon. The majority of hemorrhoids can be managed nonoperatively with medical management or office-based procedures. The authors review the anatomy, pathophysiology, presentation, and management of hemorrhoids.

Stapled hemorrhoidopexy for prolapsing hemorrhoids is conceptually different from excision hemorrhoidectomy. It does not accompany the pain that usually occurs after resection of the sensitive anoderm. This study was carried out to evaluate the clinical outcome of stapled hemorrhoidopexy at The Aga Khan University Hospital.

A sample of 140 patients with symptomatic second-, third-, and fourth-degree hemorrhoids and circumferential mucosal prolapse underwent stapled hemorrhoidopexy from July 2002 to July 2007. They were evaluated for postoperative morbidity, analgesic requirement, and recurrence.

Seventy-eight percent were males and the mean age was 45 (range 16-90) years. The mean operative time was 35 (15-78) min. The mean parenteral analgesic doses during the first 24 h were 2.1. All patients received oral analgesics alone after 24 h. No significant postoperative morbidity was observed. The mean in-patient hospital stay was 1.3 (0-5) days. Patients were followed-up for 24 (range, 2-48) months. Minor local recurrence of hemorrhoids was seen in four patients and was managed by band ligation.

Stapled hemorrhoidopexy procedure was found safe, well tolerated by patients with minimal parenteral analgesic use and early discharge from the hospital.

The aim of this study was to perform a systematic review and meta-analysis of the short- and long-term outcomes of stapled haemorrhoidopexy.

A literature search identified randomised controlled trials comparing stapled haemorrhoidopexy with Milligan-Morgan/Ferguson haemorrhoidectomy. Data were extracted independently for each study and differences analysed with fixed and random effects models.

Thirty-four randomised trials and two systematic reviews were identified, and 29 trials included. Stapled haemorrhoidopexy was statistically superior for hospital stay (p < 0.001) and numerically superior for post-operative pain (peri-operative and mid-term), operation time and bleeding (post-operative and long-term). Recurrent prolapse and re-intervention for recurrence were more frequent following stapled haemorrhoidopexy. No difference was observed in the rates of complications.

Stapled haemorrhoidopexy reduces the length of hospital stay and may have an advantage in terms of decreased operating time, reduced post-operative pain and less bleeding but is associated with an increased rate of recurrent prolapse.

The aim of this randomized prospective trial was to compare LigaSure and conventional diathermy haemorrhoidectomy.

Two hundred and eighty-four patients with grade III or IV haemorrhoids were randomized to LigaSure or diathermy (Milligan-Morgan) haemorrhoidectomy as a day-case procedure. Operating time, postoperative pain score, hospital stay, postoperative complications, wound healing time and time to return to normal activities were assessed. Thirty-four patients were lost to follow-up.

The mean operating time for LigaSure haemorrhoidectomy was significantly shorter than that for diathermy (P = 0.011). Patients treated with LigaSure had significantly less postoperative pain (measured on a visual analogue scale; P = 0.010), a shorter wound healing time (defined as time to absence of swelling; P = 0.012) and less time off work (P = 0.010) than patients who had diathermy. Neither postoperative complications nor mean hospital stay (day-case surgery) were significantly different.

LigaSure haemorrhoidectomy demonstrates simplicity, reproducibility, a low complication rate, fast wound healing, a quick return to work and reduced postoperative pain.

Surgery is the most effective treatment in patients with symptomatic grade III-IV hemorrhoids who have not responded to outpatient treatment, when there is associated abnormalities (anal fissure, anal fistula, skin tags) and in thrombosed hemorrhoids. Hemorrhoidectomy is currently the "gold standard" treatment. Randomized controlled trials comparing open with closed hemorrhoidectomy show no significant differences in pain scores. Stapled hemorrhoidectomy produces less postoperative pain than hemorrhoidectomy but is less effective in terms of symptom control. No treatment is superior to others in reducing postoperative pain except the use of drugs and anesthetic techniques. In patients with prolapsed internal hemorrhoids and thrombosed hemorrhoids, treatment may initially consist of an urgent hemorrhoidectomy with the same results as those obtained with elective surgery.

We have audited our 5 years experience of circumferential-stapled haemorrhoidopexy (PPH).

A prospectively collected electronic data base of our 5-year experience to September 2005 has been examined.

A total of 357 consecutive patients (220 - 62% women, median age 46 years; range 28-92) with symptomatic third- and fourth-degree haemorrhoids (ratio 222:135) have undergone a stapled haemorrhoidopexy/rectal mucosectomy. One hundred and thirty-two (37%) had failed previous banding; 42 (12%) had undergone a Milligan-Morgan haemorrhoidectomy in the past. All but one was performed under general anaesthetic. Mean duration of surgery was 15 min (range 11-40); 299 (84%) were planned day cases (three patients were admitted overnight for pain relief (2) and retention of urine) and 57 were planned successful overnight stays. Reactive postoperative bleeding requiring a blood transfusion occurred in three patients (0.8%): one returned to theatre (0.2%). Three patients (0.8%) had a secondary haemorrhage requiring a hospital visit, one was admitted overnight. Four patients complaining of severe pain were managed in the community. Transient urgency was reported in 92 patients (26%); 58 (63%) were men, faecal impaction 4 (1.1%), minor staple line stenosis requiring dilatation 5 (1.4%), peri-anal sepsis from an associated untreated chronic anal fissure 1 (0.2%). Normal work was resumed between 3 and 31 days (median 7). Five patients re-presented with recurrent symptoms between 14 & 18 months: further treatment comprised a repeat PPH in three (one was very painful), banding 1 and reassurance alone. A further patient re-presented with minor soiling which responded to physiotherapy.

Stapled haemorrhoidopexy/rectal mucosectomy is a safe, effective and predictable treatment of third- and fourth- degree haemorrhoids and in the majority of patients can be carried out on a day case basis.

The aim of this study was to compare the outcomes between the LigaSure vessel sealing system and the conventional closed Ferguson hemorrhoidectomy procedure performed by diathermy.

A series of 84 patients with grades III and IV hemorrhoids were randomized into two groups: (1) LigaSure hemorrhoidectomy with submucosal dissection (42 patients) and (2) Ferguson hemorrhoidectomy (42 patients). The patient demographics, operative details, parenteral analgesic requirement, postoperative pain score (assessed by an independent assessor), operating time, intraoperative blood loss, hospital stay, early and delayed complications, and time off from work or normal activity were recorded. The patients were regularly followed up at 1, 2, 4, 6, and 8 weeks after surgery.

There were no statistically significant differences between the two groups in terms of age, gender, duration of symptoms, grade of the hemorrhoid(s), or number of hemorrhoids resected. The mean operating time for LigaSure hemorrhoidectomy with submucosal dissection was significantly shorter than that for the Ferguson hemorrhoidectomy (11.3 +/- 0.4 vs. 34.2 +/- 0.7 minutes; P < 0.0001). Patients treated with the LigaSure method had significantly less blood loss (P < 0.0001), a better pain score (P < 0.0001), less parenteral analgesic requirement (P < 0.0001), shorter hospital stay (P < 0.0001), and less time off from work or normal activity (P < 0.0001). There was no difference in the early and delayed postoperative complications between the two groups.

LigaSure hemorrhoidectomy with submucosal dissection is a safe, effective procedure for grade III and IV hemorrhoids. Patients derive greater short-term benefits: reduced intraoperative blood loss, operating time, and postoperative pain as well as earlier resumption of work or normal activity. Long-term follow-up with a larger number of patients is required to confirm the long-term results of this procedure.

Stapled hemorrhoidopexy is a new procedure for the treatment of symptomatic internal hemorrhoids. Experience and prospective trials are helping to define this procedure's role. Published data confirm that stapled hemorrhoidopexy offers similar control of symptoms with the benefits of reduced postoperative pain when compared with excisional techniques. Reduction in pain is the most significant benefit of this operation. Clearly, the cost of the stapling device exceeds the cost of the sutures required to perform an excisional hemorrhoidectomy. Patients should undergo medical therapy and rubber band ligation first; however, patients being considered for excisional hemorrhoidectomy should be offered stapled hemorrhoidectomy as a less painful alternative.

Recent reports of serious sepsis following stapled haemorrhoidectomy have raised concerns about the appropriate treatment of haemorrhoidal disease.

A Medline search was undertaken for reports of sepsis following the commonly practised conservative and surgical treatments of haemorrhoids.

Published accounts of significant septic complications after injection sclerotherapy, rubber-band ligation, cryotherapy, open and closed haemorrhoidectomy, and stapled haemorrhoidectomy are discussed. This is supplemented by the authors' own experiences of stapled haemorrhoidectomy.

Septic complications following both conservative and surgical treatment of haemorrhoids are rare but may be catastrophic. Immunological compromise poses an additional risk for many treatment modalities. The technique of stapled haemorrhoidectomy should be learned diligently to avoid septic complications.

The aim of this study was to compare the results of stapled haemorrhoidopexy (commonly called stapled haemorrhoidectomy) with those of conventional diathermy haemorrhoidectomy.

Fifty-five patients with symptomatic third- and fourth-degree haemorrhoids were randomized to either stapled haemorrhoidopexy (n = 27) or conventional diathermy haemorrhoid ectomy (n = 28). Operating time, postoperative pain, time to return to work, postoperative complications and effectiveness of haemorrhoidal symptom control were recorded. The mean follow-up was 15.9 months in the stapled haemorrhoidopexy group and 15.2 months in the conventional haemorrhoidectomy group.

Mean pain intensity was significantly less in the stapled group (P = 0.001). There were no significant differences in the total number of complications, the length of absence from work or control of symptoms. Seven patients in the stapled group re-presented with prolapse compared with none in the conventional haemorrhoidectomy group (P = 0.004). This difference was also observed in the subset of patients with fourth-degree haemorrhoids (P = 0.003).

The stapled operation was significantly less painful than conventional haemorrhoidectomy. However, the rate of recurrent prolapse was higher after stapled haemorrhoidopexy than after conventional diathermy haemorrhoidectomy.

The introduction of a stapling technique for the treatment of haemorrhoids has the potential for less postoperative pain, a short operating time and an early return to full activity. The outcome of stapled haemorrhoidectomy was compared with that of current standard surgery in a randomized controlled study.

Two hundred patients were randomized to either stapled haemorrhoidectomy (n = 100) or Milligan-Morgan haemorrhoidectomy (n = 100) between March 1997 and December 1998. Each patient received standardized postoperative analgesic and laxative regimens, and completed a linear analogue pain score every 6 h during the first day after operation, after the first motion and daily until the end of the first week. Operating time, frequency of postoperative analgesic intake, hospital stay, time to return to normal activity and postoperative complications were also recorded.

The mean(s.d.) age of patients in the stapled and surgical groups was 44.1(3.2) and 49.1(12.2) years respectively. The stapled group had a shorter operating time, less frequent postoperative analgesia intake, shorter hospital stay and earlier return to normal activity. Early and late complications, and functional outcome were better in the stapled group.

Use of a circular stapler in the treatment of haemorrhoidal disease was safe, and was associated with fewer complications than conventional haemorrhoidectomy.

The aim of this study was to compare the results of conventional open haemorrhoidectomy as currently practised in Italy (group 1) with stapled haemorrhoidectomy using a 33-mm circular stapling device (group 2).

One hundred patients with symptomatic third- and fourth-degree haemorrhoids were enrolled by five hospitals. Patients were allocated to the two groups according to a centralized randomization scheme featuring five permutated blocks of 20. Preoperative clinical examination and anorectal manometry demonstrated no features of anal incontinence. Patients had a clinical and manometric re-evaluation after operation and were asked to complete a clinical diary. After a median of 16 (range 8-19) months patients were administered a standardized questionnaire by telephone.

Postoperative bleeding requiring haemostatic procedures occurred in three patients in each group. Patients in group 1 complained of moderate pain for a median of 5.3 (range 0-19) days compared with 3.1 (range 0-10) days in group 2 (P = 0.01), while severe pain was present for 2.3 (range 0-24) days in group 1 but only for 1 (range 0-14) day in group 2 (P = 0.03). The median hospital stay was 2 days in group 1 compared with 1 day in group 2 (P = 0.01). In the early days after operation, patients in group 2 had greater difficulty in maintaining normal continence to liquid stools (P = 0.01), but after 30 days the continence score was better in group 2 (P = 0.04).

Stapled haemorrhoidectomy is as effective as conventional haemorrhoidectomy. Reduced postoperative pain, shorter hospital stay and a trend toward earlier return to work suggest short-term advantages for the stapled technique.

The aim of this study was to compare diathermy and Harmonic Scalpel hemorrhoidectomy.

Fifty consecutive patients were randomly assigned to 2 groups: Group 1 (diathermy) and Group 2 (Harmonic Scalpel).

The median duration of surgery was 10 minutes for both groups. The median number of pethidine injections used for both groups was zero. The median number of oral analgesic tablets taken was 13 by Group 1 and 14 by Group 2 patients. The median number of tubes of lidocaine jelly used was two by Group 1 and three by Group 2. There was no statistical difference between pain scores recorded by both groups. Five patients in Group 1 developed posthemorrhoidectomy bleed vs. one patient in Group 2 (P = NS).

Hemorrhoidectomy by Harmonic Scalpel is comparable to diathermy hemorrhoidectomy in terms of postoperative pain and complications.

Haemorrhoidectomy has proven long-term efficacy in the treatment of haemorrhoids, albeit at the price of increased pain and complications compared with other modalities. This study reviews the literature and describes best practice in the surgical treatment of haemorrhoids.

A Medline search was conducted using the keywords haemorrhoids or haemorrhoidectomy to identify clinical trials comparing different surgical treatments for haemorrhoids.

Many studies were small and follow up was often short-term only. Surrogate measures such as post-operative pain scores and changes in anorectal physiology were commonly assessed in preference to efficacy in symptom reduction. Haemorrhoidectomy may be safely performed under general, local or regional anaesthesia according to patient fitness and local practice. Results of randomized controlled trials indicate that there open and closed techniques of haemorrhoidectomy are equivalent. There is no evidence to support the practice of laser haemorrhoidectomy. Diathermy haemorrhoidectomy achieves good haemostasis and permits an anal dressing to be omitted, but is not superior to conventional techniques. The use of preoperative lactulose and post-operative oral metronidazole is supported by randomized controlled trials.

Haemorrhoidectomy is currently the most effective treatment for prolapsing haemorrhoids. There is little evidence to support the use of one surgical technique over another. With attention to detail and adjuncts to reduce post-operative pain, haemorrhoidectomy may be performed as day surgery.

Haemorrhoidectomy is commonly an inpatient procedure because it is frequently associated with postoperative pain. Day case haemorrhoidectomy is a similar operation to that used on inpatients but with different strategies for managing postoperative pain. Circumferential mucosectomy (stapled haemorrhoidectomy) may be associated with less postoperative pain than conventional haemorrhoidectomy. We compared stapled haemorrhoidectomy with conventional haemorrhoidectomy in patients with third degree haemorrhoids.

We randomly assigned 22 patients to conventional haemorrhoidectomy by the diathermy dissection or to stapled haemorrhoidectomy with the use of an intraluminal stapling device. Patients were discharged when free of pain, took co-codamol as required, completed visual analogue charts each day, and were assessed at 1 and 6 weeks postoperatively for symptom control.

All patients received the assigned treatment. Mean inpatient stay was lower in the group assigned to stapled as opposed to conventional haemorrhoidectomy (1.09 [0.3] vs 2.82 [0.09] nights, p<0.001), experienced less pain overall (p=0.003), and returned to normal activities sooner (8.1 [1.53] vs 16.9 [2.33] days, p<0.005). Stapled haemorrhoidectomy controlled symptoms of prolapse, discharge and bleeding in all patients.

Stapled haemorrhoidectomy is an effective treatment for third degree haemorrhoids with significant advantages for patients compared with conventional haemorrhoidectomy.

Surgical haemorrhoidectomy has a reputation for being a painful procedure for a fairly benign disorder. The circular transanal stapled technique for the treatment of haemorrhoids has the potential to offer a less painful rectal procedure in place of ablative perianal surgery. We compared the short-term outcome of the circular stapled procedure for haemorrhoids with current standard surgery in a randomised controlled trial.

40 patients admitted for surgical treatment of prolapsing haemorrhoids were randomly assigned to Milligan-Morgan haemorrhoidectomy (n=20) or the circular stapled procedure. Under general anaesthesia patients underwent standardised diathermy excision haemorrhoidectomy or had a circumferential doughnut of rectal mucosa and submucosa above the dentate line excised and closed with a standard circular end-to-end stapling device. All patients received standardised preoperative and postoperative analgesic and laxative regimens. Patients completed linear analogue pain charts each day and were interviewed at 1, 3, and 6-10 weeks postoperatively. Summary measures of average pain experience were calculated from 10 cm linear analogue pain scores and were used as the primary outcome measure.

The stapled group had shorter anaesthesia time (median 18 [range 9-25] vs 22 [15-35] mins). Average pain in the stapled group was significantly lower than it was in the Milligan-Morgan group (2.1 [0.2-7.6] vs 6.5 [3.1-8.5], 95.1% CI difference medians 1.9-4.7, p<0.0001. Mann-Whitney U test). Average pain relative to what the patient expected was also significantly less in the stapled group (-2.8 [-4.4 to 1.3] vs 0.7 [-1.8 to 3.4]. Hospital stay and time to first bowel motion were not significantly different between groups. Return to normal activity was significantly shorter in the stapled group (17 [3-60] vs 34 [14-90]. Early and late complications, patient-assessed symptom control, and functional outcome appear similar after short-term follow-up.

The circular stapled technique offers a significantly less painful alternative to Milligan-Morgan haemorrhoidectomy and is associated with an earlier return to normal activity. Early symptom control and functional outcome appear similar. However, long-term symptomatic and functional outcome need further study.

The aim of this study was to compare closed (Ferguson) hemorrhoidectomy to open (Milligan-Morgan) hemorrhoidectomy regarding postoperative conditions, complications, and long-term results.

This was a randomized study of 77 patients with second-degree or third-degree hemorrhoids suitable for hemorrhoidectomy. In 39 patients the Milligan-Morgan procedure was used, and in 38 patients the Ferguson procedure was used. Details of operations, postoperative complications, and length of postoperative stay were recorded. Pain was assessed from a visual analog scale and by registration of postoperative analgesic medication. Follow-up was done at three weeks, six weeks, and by visit or telephone interview after at least a year.

No statistically significant differences were found between the two methods regarding complications, pain, or postoperative stay. There were four reoperations for bleeding, all after Milligan-Morgan operations. At follow-up after three weeks 86 percent of the Ferguson patients had completely healed wounds, and none had signs of infection. Of the Milligan-Morgan patients, only 18 percent had completely healed wounds, and symptoms of delayed wound healing were significantly more frequent. One patient had a superficial wound infection. After one year more than 10 percent in each group had recurrent hemorrhoids with symptoms.

Both methods are fairly efficient treatment for hemorrhoids, without serious drawbacks. The closed method has no advantage in postoperative pain reduction, but wounds heal faster, and the risk of wound dehiscence seems exaggerated.

Ligation excision haemorrhoidectomy is usually performed on an inpatient basis. This study was designed to assess the feasibility of day-case haemorrhoidectomy.

Patients fulfilling criteria for day surgery underwent ligation excision haemorrhoidectomy with the intention of a same-day discharge from hospital. A standardized protocol for anaesthesia, perioperative analgesia and antiemesis was followed. Patients received daily home nursing visits until they felt both comfortable and confident. Staff recorded pain and nausea scores on a visual analogue scale (range 1-10) until the first bowel action. Patient satisfaction was assessed independently after operation.

Fifty-one patients underwent planned day-case haemorrhoidectomy. Forty-two (82 per cent) were discharged on the day of surgery. All patients were discharged within 26 h of surgery. Four patients required readmission, two with reactive bleeding, one with urinary retention and one for pain control. Pain and nausea were well controlled. Forty-four patients (86 per cent) were totally or very satisfied with their overall care.

Ligation excision haemorrhoidectomy can be performed successfully as a day-case procedure.

Haemorrhoidectomy is commonly an inpatient procedure because patients and doctors worry about postoperative pain. Day-case haemorrhoidectomy (DCH) is possible if patient anxiety is addressed and postoperative pain and bowel function are managed. Pain sometimes increases a few days after haemorrhoidectomy, possibly because of secondary infection. We studied the effect of metronidazole on pain after DCH.

We randomly assigned 40 consecutive patients admitted for DCH metronidazole 400 mg (n = 20) or placebo (n = 20) three times daily, both for 7 days. All patients received lactulose from 2 days before surgery for 2 weeks. Diathermy DCH was performed without pedicle ligature or anal-canal dressing, and a diclofenac suppository was administered at the end of the procedure. Patients were discharged on the same day with diclofenac, 0.2% glyceryl-trinitrate ointment, lactulose, a telephone number to call for queries in emergencies, and an outpatient appointment. Patients took paracetamol or Co-dydramol (dihydrocodeine and paracetamol) as required; they completed linear analogue charts every day and completed questionnaires on satisfaction at 1 and 6 weeks.

34 patients had all three major piles excised, of whom seven had additional division and reconstruction of the posterior skin bridge. Overall, both groups of patients experienced less pain than expected, except on days 3 and 4. Patients in the metronidazole group had significantly less pain than those in the placebo group on days 5, 6, and 7 (p = 0.004, p = 0.02, and p = 0.006). Median time to return to work or normal activity was 15 days (range 12-28) in the metronidazole group and 18 days (7-34) in the placebo group (p = 0.009). The patient satisfaction score was higher in the metronidazole group than in the placebo group at 1 week (p = 0.005).

Prophylactic metronidazole in diathermy DCH suppressed secondary pain around days 5-7 and increased patient satisfaction and earlier return to work.

A prospective trial was conducted to compare haemorrhoidectomy alone (control, group 1) with haemorrhoidectomy plus lateral internal sphincterotomy (group 2) for prolapsed piles. Some 33 patients (18 men, 15 women) of mean(s.e.m.) age 40(2.3) years were randomized, 16 to group 1 and 17 to group 2. There were no significant differences in postoperative pain scores. Mean resting and maximum anal squeeze pressures, studied 6 weeks and 3 months after operation, were generally lower in group 2, but were not significantly different. Two patients in group 2 were distressed by incontinence to liquid faeces which persisted in one after 1 year. There were no other complications in either group after a mean(s.e.m.) follow-up of 11(0.4) months. The addition of lateral internal sphincterotomy to routine haemorrhoidectomy is unnecessary and carries the added risk of incontinence.

This study was undertaken to evaluate ambulatory hemorrhoidectomy using the CO2 laser.

Ninety consecutive patients (50 males, 40 females), 80 percent of whom had second or third degree hemorrhoids, had ambulatory hemorrhoidectomy performed with a CO2 laser in the left lateral Sims position under local anesthesia and intravenous sedation. Dissection was entirely performed with the CO2 laser using an open technique.

One patient with polycythemia vera was admitted subsequently for secondary hemorrhage. All but three patients had healed within four weeks. No long-term sequelae were encountered.

These results compare favorably with those obtained by others and show that ambulatory laser hemorrhoidectomy may simplify management in selected patients.

The purpose of this study was to assess whether any method of hemorrhoid therapy has been shown to be superior in randomized, controlled trials.

A meta-analysis was performed of all randomized, controlled trials assessing two or more treatment modalities for symptomatic hemorrhoids. Outcome variables included response to therapy, need for further therapy, complications, and pain.

A total of 18 trials were available for analysis. Hemorrhoidectomy was found to be significantly more effective than manual dilation of the anus (P = 0.0017), with less need for further therapy (P = 0.034), no significant difference in complications (P = 0.60), but significantly more pain (P < 0.0001). Patients undergoing hemorrhoidectomy had a better response to treatment than did patients treated with rubber band ligation (P = 0.001), although complications were greater (P = 0.02) as was pain (P < 0.0001). Rubber band ligation was better than sclerotherapy in response to treatment for all hemorrhoids (P = 0.005) as well as for hemorrhoids stratified by grade (Grades 1 to 2; P = 0.007; Grade 3 hemorrhoids, P = 0.042), with no difference in the complication rate (P = 0.35). Patients treated with sclerotherapy (P = 0.031) or infrared coagulation (P = 0.0014) were more likely to require further therapy than those treated with rubber band ligation, although pain was greater after rubber band ligation (P = 0.03 for sclerotherapy; P < 0.0001 for infrared coagulation).

Rubber band ligation is recommended as the initial mode of therapy for Grades 1 to 3 hemorrhoids. Although hemorrhoidectomy showed better response rates, it is associated with more complications and pain than rubber band ligation, thus should be reserved for patients who fail to respond to rubber band ligation.

Anal stricture is an uncommon but well recognized complication following haemorrhoidectomy. Twenty-seven (3.8%) out of 704 (500 elective and 204 emergency) cases of haemorrhoidectomy performed at the Singapore General Hospital over a 24 month period had clinical evidence of anal stricture post-haemorrhoidectomy. Of the 27 cases, 15 had haemorrhoidectomy as an elective procedure while 12 had it performed as an emergency procedure (chi 2 = 3.26, 1 d.f., P > 0.05, not significant). The mean interval between surgery and presentation of anal stricture was 6 weeks (range 3-12 weeks). Eighteen of the patients were managed by anal dilatation in the outpatient clinic combined with bulk laxatives and a local anaesthetic agent. The other nine patients required a minor surgical procedure comprising either a lateral internal sphincterotomy (five) or an anoplasty (four) procedure. All patients were well, following treatment. None of these patients developed a recurrent stricture at follow up 3 months after treatment. It was concluded that although anal stricture following haemorrhoidectomy is rare, it should be detected and treated early in order to avoid pain and suffering, and treatment is usually successful.
