RESUMO
Background: Acute appendicitis represents one of the main causes of surgical emergencies. It can be approached as open appendectomy or laparoscopic appendectomy (LA). LA uses different modalities, such as conventional laparoscopic appendectomy (CLA) or single-port laparoscopic appendectomy (SPLA). The aim of this work is to compare the results of CLA versus SPLA in patients diagnosed with Acute Appendicitis. Materials and Methods: A comparative multicenter prospective study of patients undergoing LA with a clinical diagnosis of acute appendicitis was presented. They were divided into two groups (CLA group and SPLA group). Results: A total of n = 147 patients were included (72 CLA and 75 SPLA). Preoperative and intraoperative times were shorter for patients undergoing CLA (P = .002; P = .068). Postoperative and reinsertion time was lower for SPLA (P = .000; P = .0004). There were no differences in postoperative complications. The type of approach showed statistically significant differences with respect to pain within the first 12 hours of the postoperative period, as well as at discharge, while no differences were observed in relation to cosmetic satisfaction when the two approaches were compared. Conclusion: SPLA technique presented less intraoperative time, shorter time of labor reinsertion, and less postoperative pain. There were no statistically significant differences in postoperative complications.
