Single-port laparoscopic surgery in acute appendicitis: retrospective comparative analysis for 618 patients

Transumbilical single-port laparoscopic appendectomy (SPLA) is a promising procedure that features less pain, faster recovery of postoperative bowel function and superior cosmetic results. We performed a retrospective comparative analysis of SPLA versus conventional laparoscopic surgery (CLA) to evaluate the safety and efficacy in acute appendicitis.
From December 2008 to November 2013, laparoscopic surgery was performed on 636 patients with acute appendicitis at the Department of Surgery, Chuncheon Sacred Heart Hospital. Under approval of Institutional Review Board, data concerning baseline characteristics, operative outcomes, postoperative complications and postoperative functional recovery were compared between both procedures.
After exclusion of 18 patients, 618 patients treated for acute appendicitis were included. SPLA was performed in 375 patients and CLA in 243 patients. Complicated appendicitis was more prevalent in the CLA group (26.3 %) than in the SPLA group (17.1 %) (p = 0.005). There was no difference between groups in operation time (p = 0.235), postoperative duration of hospital stay (p = 0.672) and readmission rate (p = 0.688). The rate of postoperative complications was similar in both groups (10.7 % in SPLA vs. 11.1 % in CLA, p = 0.862). In subgroup analysis of complicated appendicitis, more patients needed conversion to open surgery in the SPLA group (15.6 vs. 1.6 %, p = 0.005).
In uncomplicated appendicitis, SPLA can be performed safely and efficiently. However, more selective indication for SPLA should be applied in cases of complicated appendicitis because of the greater risk of open conversion.
