Purpose: Acute appendicitis is one of the most common surgical emergencies worldwide. Laparoscopic appendectomy (LA) is being accepted as the ‘gold standard’ surgery for simple acute appendicitis over open appendectomy (OA); however, for complicated appendicitis, no consensus has been reached with regard to which produces better outcomes.
Methods: We analyzed the data of patients who were diagnosed as complicated appendicitis, older than 18 years old, and underwent LA or OA from January 2008 to December 2012. A total of 2,173 patients had acute appendicitis during this period and 461 (21.2%) of them had complicated appendicitis; 335 patients were finally enrolled and divided into LA (280), OA (49), and Converted to open Appendectomy (CA) groups (6), respectively. Age, sex, preoperative WBC, operating time, stapler usage, time to diet and discharge, total cost and complication among the three groups were analyzed.
Results: No significant differences were observed in sex, age, history of abdominal surgery, preoperative WBC, and total cost. Shorter operating time (62.3±30.0 vs 87.3±40.2, p=0.000), shorter time to diet (2.7±2.2 vs 3.7±1.6, p=0.001), shorter postoperative stay (4.8±2.6 vs 7.1±2.5, p=0.000), shorter duration of pain (3.4±1.7 vs 5.6±2.8, p=0.000), and less frequent usage of pain killer (68.2% vs 89.1%, p ＜0.001) were observed in the laparoscopic group. Complication rate was significantly lower in the LA group (4.6% vs 18.4%, p=0.002).
Conclusion: Results of this study provide clinical evidence that laparoscopic surgery is a feasible and safe surgical modality for complicated appendicitis. Conduct of more reliable, large scaled, randomized prospective study will be necessary in order to prove the superiority of laparoscopic surgery for complicated appendicitis.
