Emergency Laparoscopic Sigmoidectomy for Perforated Diverticulitis with Generalised Peritonitis: A Systematic Review

Background: Laparoscopic sigmoidectomy for diverticulitis has initially been confined to the elective setting. However, open acute sigmoidectomy for perforated diverticulitis is associated with high morbidity rates that might be reduced after laparoscopic surgery. The aim of this systematic review was to assess the feasibility of emergency laparoscopic sigmoidectomy for perforated diverticulitis. Methods: We performed a systematic search of PubMed, EMBASE and CENTRAL. All studies reporting on patients with perforated diverticulitis (Hinchey III-IV) treated by laparoscopic sigmoidectomy in the acute phase were included, regardless of design. Results: We included 4 case series and one cohort study (total of 104 patients) out of 1,706 references. Hartmann's procedure (HP) was performed in 84 patients and primary anastomosis in 20. The mean operating time varied between 115 and 200 min. The conversion rate varied from 0 to 19%. The mean length of hospital stay ranged between 6 and 16 days. Surgical re-intervention was necessary in 2 patients. In 20 patients operated upon without defunctioning ileostomy, no anastomotic leakage was reported. Three patients died during the postoperative period. Stoma reversal after HP was performed in 60 out of 79 evaluable patients (76%). Conclusions: Acute laparoscopic sigmoidectomy for the treatment of perforated diverticulitis is feasible in selected patients provided they are handled by experienced hands. (C) 2015 S.
