Colorectal anastomosis is a sophisticated problem that demands an elaborate discussion and an elegant solution. "Those who forget the past are condemned to repeat it." George Santayana, Life of Reason , 1905.

This study was designed to evaluate a new technique for a completely diverting tube ileostomy achieved through temporary occlusion of the distal ileum using a flexible rubber strip.

This prospective interventional study was conducted in one centre. Patients who underwent colorectal resections with a primary anastomosis and who were deemed as requiring a defunctioning stoma were included in the study. After completion of resection and anastomosis, the tube ileostomy was fashioned by inserting a reinforced (spiral) endotracheal tube with an inner diameter of 7.5 mm into the ileum. To provide complete faecal diversion, temporary occlusion of the distal ileum was performed using a flexible rubber strip. The primary outcome of this study was the incidence of complete diversion achieved using this method.

Fifty consecutive patients underwent a diverted tube ileostomy using the technique described above. Defaecation before removal of the strip did not occur in any of the patients inferring that complete diversion was observed in all patients (100%). The tube was removed at postoperative week 3. After tube removal, the resulting enterocutaneous fistulas closed spontaneously in a median of 6 (2-30) days.

The diverting tube ileostomy technique using an easily removable rubber strip to defunction the colorectal anastomosis is a safe and effective method that precludes the need to fashion a stoma.

To introduce natural orifice transgastric endoscopic surgery (NOTES) tube ileostomy using pelvis-directed submucosal tunneling endoscopic gastrostomy and endoscopic tube ileostomy.

Six live pigs (three each in the non-survival and survival groups) were used. A double-channeled therapeutic endoscope was introduced perorally into the stomach. A gastrostomy was made using a 2-cm transversal mucosal incision following the creation of a 5-cm longitudinal pelvis-directed submucosal tunnel. The pneumoperitoneum was established via the endoscope. In the initial three operations of the series, a laparoscope was transumbilically inserted for guiding the tunnel direction, intraperitoneal spatial orientation and distal ileum identification. Endoscopic tube ileostomy was conducted by adopting an introducer method and using a Percutaneous Endoscopic Gastrostomy Catheter Kit equipped with the Loop Fixture. The distal tip of the 15 Fr catheter was placed toward the proximal limb of the ileum to optimize intestinal content drainage. Finally, the tunnel entrance of the gastrostomy was closed using nylon endoloops with the aid of a twin grasper. The gross and histopathological integrity of gastrostomy closure and the abdominal wall-ileum stoma tract formation were assessed 1 wk after the operation.

Transgastric endoscopic tube ileostomy was successful in all six pigs, without major bleeding. The mean operating time was 71 min (range: 60-110 min). There were no intraoperative complications or hemodynamic instability. The post-mortem, which was conducted 1-wk postoperatively, showed complete healing of the gastrostomy and adequate stoma tract formation of ileostomy.

Transgastric endoscopic tube ileostomy is technically feasible and reproducible in an animal model, and this technique is worthy of further improvement.

The aim of this study is to introduce a new technique of modified spontaneously closed defunctioning tube ileostomy after anterior resection of the rectum for rectal cancer with a low colorectal anastomosis. Patients with rectal cancer who underwent anterior resection of rectum with a low colorectal anastomosis and chose a modified defunctioning tube ileostomy between March 2012 and August 2013 were retrospectively reviewed. Data on the success of the operation procedures, post-operative hospital stay, and post-operative tube ileostomy-related complications were analyzed. One hundred fifty-two patients (87 males and 65 females; 57.1 ± 17.4 years) undergoing the modified defunctioning tube ileostomy after anterior resection for rectal cancer were included. The post-operative hospital stay was 11.9 ± 3.2 days. The tube was removed on days 22.6 ± 4.1 after operation and the ileostomy wound closed spontaneously within 13.1 ± 1.9 days. Twenty-five patients felt tube-associated pain or discomfort, which was relieved after a period of adaptation and appropriate tube adjustment. Nine patients suffered from tube blockage and were treated successfully with saline irrigation. Two patients had intestinal obstruction, which was resolved with conservative treatment. Three patients developed leakage of the distal anastomosis: two were successfully treated with conservative measures and the other completely recovered after reoperation. The modified spontaneously closed defunctioning tube ileostomy appears efficacious and safe. This technique may be used to protect the distal anastomosis and simultaneously decrease the ileostomy complications, and minimize the morbidity and mortality associated with stoma takedown.

Tube ileostomy may be an alternative technique to loop ileostomy for protection of distal anastomosis, but its evidence base has not yet been established. This systematic review aims to evaluate the use of tube ileostomy and compare the outcomes associated with it.

A systematic literature search of MEDLINE, EMBASE, Web of Science and the Cochrane database was conducted. Studies reporting on elective left-sided/colorectal anastomosis were included. Studies which reported on emergent surgery, small bowel anastomosis or tube ileostomy as a bridging procedure were excluded. The intra-operative technique, postoperative management and complications were assessed. Outcome measures included anastomotic leak, reoperation and complications related to the stoma or tube ileostomy.

Seven studies met the inclusion criteria. Three were case series with 101 patients and four were nonrandomized comparative studies with 665 patients. Pooled analyses of three comparative studies, comparing tube ileostomy (n = 278) with loop ileostomy (n = 254), revealed no significant differences in anastomotic leak rates (pooled OR 0.85, 95% CI 0.41-1.75; I(2) = 0%, P = 0.43).

There is a re-emergence of interest in the use of tube ileostomy to defunction a distal anastomosis. Pooled analyses of studies comparing tube ileostomy with loop ileostomy do not show statistically significant differences in anastomotic leak rates. Further refinement of this technique and randomized controlled studies are necessary for this technique to be routinely taken up by surgeons.

This study was designed to compare the long-term surgical outcomes of patients with mid and low rectal cancer after open or hand-assisted laparoscopic surgery (HALS).

A case-matched controlled prospective analysis of 116 patients who underwent hand-assisted laparoscopic surgery (HALS) for stage I to III mid and low rectal cancer from 2005 to 2010 was performed. Contemporary patients who underwent open rectal surgery were matched to the HALS group at the ratio of 1:1. The perioperative clinical outcomes, postoperative pathology, and survival outcomes were compared between the groups.

The patient characteristics between the two groups were comparable. Ninety patients in the open group and 85 in the HALS group received sphincter-preserving surgery. HALS resulted in less blood loss and wound infection, faster return to oral diet, shorter postoperative hospital stay, and longer operating time. The two groups had similar complication rates. Lymph node retrieval and involvement of circumferential and distal margins were similar for both procedures. Cumulative incidences of locoregional recurrence, disease-free, or overall survival rates were statistically similar.

This study suggests that HALS for mid and low rectal cancer is acceptable in terms of short-term clinical outcomes and long-term survival results.

Temporary bowel ligation (TL) has been proposed to prevent contamination as a damage control procedure in multiple bowel perforations. However, bacteria translocation and intestinal ischemia may develop in a prolonged duration. We here hypothesized that intraintestinal drainage combined with temporary ligation (D-TL) would decrease intestinal injury and improve survivals in a gunshot multiple bowel perforation swine model in the setting of a damage control surgery.

The abdomen was shot one time with an experimental modified gun whereas pigs were hemorrhaged to a mean arterial pressure of 40 mm Hg and maintained in shock for 40 min. Cold lactated Ringer solution was gradually infused to induce hypothermia. Animals were randomized to primary anastomosis, TL and intraintestinal D-TL groups (n = 8). Animals were resuscitated for 12 h with the shed blood and lactated Ringer solution. Delayed anastomosis was performed in TL and D-TL animals after resuscitation. Surviving animals were humanely killed 24 h after operation. Systemic hemodynamic parameters were recorded and blood samples were obtained for biochemical assays. Intra-abdominal pressure, portal vein and peripheral vein bacterial cultures, small intestine hematoxylin-eosin staining, and transmission electron microscopy examination were performed at 0, 2, 6, 12, and 24 h after the surgery.

All animals suffered extreme physiologic conditions as follows: hypothermia, severe acidosis, hypotension, and depressed cardiac output. Compared with the primary anastomosis and TL group, D-TL animals required less resuscitation fluid, suffered a lower intra-abdominal hypertension and bacterial translocation, normalized lactate levels faster, had lower serum creatine kinase, aspartate aminotransferase levels and tissue TNF-α level, and nuclear factor-kB activations and thus had greater early survival.

Compared with primary intestinal anastomosis and TL, rapid bowel ligation combined with intraintestinal drainage as a damage control adjunct improved survivals in a multiple bowel perforation swine model in the setting of damage control surgery.
