Original researchLaparoscopic versus open approach in the management of appendicitis complicated exclusively with peritonitis: A single center experience

•Controversy exists regarding the use of laparoscopy in complicated appendicitis.•This study compared laparoscopic versus open approach in appendicular peritonitis.•There were no differences between groups in general and specific complications.•Our results supports laparoscopy in cases of appendicular peritonitis.

Background: Controversial evidence exists regarding the laparoscopic approach in patients with acute appendicitis complicated with peritonitis due to a higher rate of surgical complications. The aim of this study was to compare post-operatory outcomes in patients with acute appendicitis complicated exclusively with peritonitis approached by laparoscopy versus open surgery. Methods: Single center retrospective analysis of clinical records of patients with appendicitis complicated with peritonitis operated from January 2003 until October 2013. Demographic data, intra-operative variables, length of stay, surgical complications, mortality, readmissions and reoperations were retrieved. Results: 227 patients were identified, 43% males, mean age 39 ± 17 years (range: 12-85 years). Ninety-seven patients (43%) underwent laparoscopic appendectomy, 13 of them were converted to open surgery (13%). Ninety-four patients presented with diffuse peritonitis (41.4%). Laparoscopic appendectomy showed longer operative time but shorter hospital stay (p < 0.05). There were no differences in post-operatory complications (intra-abdominal abscess, surgical site infection and prolonged ileus). Laparoscopic appendectomy was associated with lower odds for developing any surgical complication in the multivariate analysis (OR 0.301, p = 0.036). Conclusion: Both approaches showed no differences in complications in the management of appendicitis complicated exclusively with peritonitis. In our experience, laparoscopic appendectomy is a safe approach in cases of appendicitis complicated exclusively with peritonitis.
