    Abstract:
    BACKGROUND: Single-incision laparoscopic surgery is a new procedure used to treat a variety of diseases requiring surgical intervention. The aim of this prospective comparative study is to compare the technical feasibility and safety of single-incision and three-port laparoscopic appendectomy. STUDY DESIGN: Between February 2009 and April 2010, 102 patients with appendicitis were enrolled in this study. The patients were randomly assigned to two groups: single-incision or three-port laparoscopic appendectomy. Patients with perforated appendicitis were not excluded. We analyzed the patients' clinical characteristics and surgical outcomes. RESULTS: There were no significant differences in preoperative patient demographics between the two groups with respect to body mass index (22.03±4.07 kg/m(2) in the single-incision group versus 21.97±3.49 kg/m(2) in the three-port group, P=.930). The pain score on the visual analog scale on postoperative Day 1 was significantly lower in the single-incision group than in the three-port group (3.22±1.22 versus 3.90±1.46, P=.012). Additionally, recovery time to daily life was significantly shorter in the single-incision group than in the three-port group (3.22±1.04 versus 3.94±1.43 days, P=.005). In patients with perforated appendicitis, the single-incision procedure took approximately 10 minutes less than the three-port procedure (44.11±7.75 versus 54.14±32.21 minutes, P=.449), and the postoperative hospital stay (P=.033) and recovery time to daily life (P=.001) were significantly shorter in the single-incision group. CONCLUSIONS: Single-incision laparoscopic appendectomy is a feasible and safe procedure, even in patients with perforated appendicitis, and this procedure is even less invasive than three-port laparoscopic surgical techniques.
