Comparison of Laparoscopic and Open Appendectomies for Perforated Appendicitis / 中国微创外科杂志

ABSTRACT

Objective To compare the efficacy of laparoscopic appendectomy(LA) and open appendectomy(OA) for perforated appendicitis.Methods From January 2002 to December 2005,40 patients with perforated appendicitis were treated at Xuanwu Hospital,20 of them received LA,and the others underwent OA.The clinical data of the patients were retrospectively analyzed.Results The operative time in the LA group was significantly longer than that in the OA group [(75.8?11.6) min vs(54.8?9.5) min,t=6.264,P=0.000)].And the patients in the LA group returned to oral intake earlier than those in the OA group [(1.8?0.5) d vs(2.6?0.5) d,t=-5.060,P=0.000].Moreover,the periods of antibiotic use and hospital stay in the LA group were significantly shorter than those in the OA group [(3.8?0.7) d vs(6.3?1.2) d,t=-8.048,P=0.000;and(5.8?1.1) d vs(11.6?1.6) d,t=-13.359,P=0.000].Although 3 patients had incision infection in the OA group,while none of the LA group had such a complication,no significant difference was detected in the complication rate between the two groups(Fisher's exact test,P=0.115).Conclusions Laparoscopic appendectomy is superior to open surgery for perforated appendicitis because of its advantages of quick recovery,short hospitalization,less antibiotic use,and minimal invasion.LA is a safe,effective,and feasible procedure for perforated appendicitis.
