In a retrospective study from Colombia, 112 patients with secondary peritonitis requiring bowel resection and managed with staged laparotomy were analyzed [116]. Deferred primary anastomosis was used in 34 EPZ-6438 in vitro patients where the bowel ends were closed at first operation

and definitive anastomoses were reconstructed at the subsequent operation following physiological stabilization in the ICU and repeated peritoneal washes until the septic source was controlled. In contrast, 78 patients underwent small bowel or colonic diversion followed by similar ICU stabilization and peritoneal washes. In both groups, the abdomens were left open at the initial operation and a Velcro system or vacuum pack was used for temporary abdominal closure. The mean number of laparotomies was four in both groups. There were more patients with colon resections in the diversion group (80% vs. 47%). There was no significant difference in hospital mortality (12% for deferred anastomosis vs. 17% for diversion), frequency of anastomotic leaks or fistulas (9% vs. 5%), or ARDS (18% vs. 31%). The authors concluded that in critically ill patients with severe secondary peritonitis managed with staged laparotomies, deferred primary anastomosis can be performed safely as long as adequate control of the septic foci and restoration of deranged physiology

is achieved prior to reconstruction. In a non-randomized study of 27 buy Cobimetinib consecutive patients with perforated diverticulitis (Hinchey III/IV), the patients were managed either with sigmoid resection and primary anastomosis, Cell Cycle inhibitor or limited sigmoid resection or JIB04 in vivo suture, open abdomen and primary anastomosis or colostomy at second operation 24–48 hours later, or Hartmann procedure; sigmoid resection and end colostomy [117]. All 6 patients with primary anastomosis

survived without complications, but there was an obvious selection bias. Of the 6 patients undergoing Hartmann’s procedure, one died of sepsis and 5 were discharged with stoma. In the interesting group of 15 patients with deferred anastomosis or stoma and open abdomen, 9 patients had intestinal continuity restored during the second look operation with one fatal anastomotic leakage. In a prospective study of 51 patients with perforated diverticulitis (Hinchey III/IV) were initially managed with limited resection, lavage and TAC with vacuum-assisted closure followed by second, reconstructive operation 24–48 hours later [118]. Bowel continuity was restored in 38 patients, in 4 protected by a loop ileostomy. Five anastomotic leaks (13%) were encountered requiring loop ileostomy (2 patients) or Hartmann’s procedure (3 patients). Postoperative abscesses were seen in 4 patients, abdominal wall dehiscence in one and re-laparotomy for drain-related small bowel perforation in one.
