Laparoscopic appendectomy (LA) is safe and effective in cases of peritonitis, perforation, and abscess. We investigated our conversion rate and clinical outcomes in this patient population, as well as preoperative factors that predict operative conversion. A retrospective nonrandomized cohort of 92 patients underwent LA for acute appendicitis with peritonitis, perforation, or abscess at our institution between 1997 and 2002. Thirty-six of the 92 were converted to open appendectomy (OA), yielding a conversion rate of 39 per cent. The presence of phlegmon (42%), nonvisualized appendix (44%), technical failures (8%), and bleeding (6%) were reasons for conversion. Preoperative data had no predictive value for conversion. CT scan findings of free fluid, phlegmon, and abscess did not correlate with findings at the time of surgery. Total complication rates were 8.9 per cent in the LA group as compared to 50 per cent in the converted cohort. Postoperative data showed LA patients stayed 3.2 days versus 6.9 days for converted patients (P = 0.01). LA patients had less pneumonia (P = 0.02), intra-abdominal abscess (P = 0.01), ileus (P = 0.01), and readmissions (P = 0.01). LA is safe and effective in patients with appendicitis with peritonitis, perforation, and abscess, resulting in shorter hospital stays and less complication.
