PURPOSE: Transumbilical laparoscopic-assisted appendectomy (TULA) is a single incision technique that uses a combined intra- and extracorporeal method. The aim of this study was to compare surgical outcomes of TULA with conventional 3-port laparoscopic appendectomy (LA). METHODS: A retrospective review of medical records between 2010 and 2014 identified 303 pediatric patients who underwent LA with uncomplicated acute appendicitis. Of these, 85 patients underwent TULA and 218 patients underwent conventional LA. Demographic data, clinical characteristics, perioperative outcomes and postoperative complications were compared between the 2 groups. RESULTS: The mean operation time in the TULA group was 30.39 minutes, which was significantly shorter than that of the LA group (47.83 minutes) (P < 0.001). The first day of oral intake after surgery was earlier (1.05 days vs. 1.32 days; P < 0.001) and the length of hospital stay was also shorter (2.54 days vs. 3.22 days; P < 0.001) for the TULA group than the LA group. Furthermore, the postoperative complication rate was lower in the TULA group (1 of 85, 1.25%) compared to the LA group (19 of 218, 8.7%) (P = 0.018). CONCLUSION: In conclusion, TULA procedure is recommended for uncomplicated appendicitis in children due to its simplicity and better postoperative outcomes.
