Abstract
PURPOSE: To compare the surgical outcomes after transumbilical laparoscopic-assisted appendectomy (TULAA) and open appendectomy (OA) at a single institution. METHODS: We compared the surgical outcomes for 94 consecutive patients who underwent TULAA between April 2010 and March 2014 to those for 91 consecutive patients who underwent OA between April 2006 and March 2010. RESULTS: There were no significant differences in the clinicopathological backgrounds between the two groups. Although the lengths of the operations were similar in both groups, the postoperative hospital stay was significantly shorter in the TULAA group (4.7 days vs. 5.4 days, P = 0.02). The need for abdominal drain insertion was significantly reduced in the TULAA group owing to sufficient intraperitoneal exploration (P = 0.03). The incidence of postoperative complications was also lower in the TULAA group, but the difference was not significant (8.6 % vs. 12.1 %, P = 0.31). In complicated cases, a lower incidence of surgical site infection was confirmed in the TULAA group (6.7 % vs. 20.7 %, P = 0.12). CONCLUSION: Our results demonstrated that TULAA provided better surgical outcomes, especially a faster recovery. TULAA could be an effective procedure incorporating both open and laparoscopic techniques, and can be implemented as a standard procedure for the treatment of appendicitis, regardless of disease severity.
