Abstract: 【Abstract】〓Objective〓To investigate the safety and feasibility of single-incision laparoscopic appendectomy (SILA) in obese patients with acute appendicitis. Methods〓Eighty adult obese patients with acute appendicitis from March 2014 to September 2015 were randomized into the experimental group and the control group. Patients in the experimental group were assigned to undergo single-incision laparoscopic appendectomy,Patients in the control group were assigned to undergo standard 3-port laparoscopic appendectomy(SLA). The terms of demography,American Society of Anesthesiologists (ASA) classification,appendicitis type,details of operations,post-operative recovery, and postoperative complications were recorded and analyzed. Results〓There were no significant differences between the two groups for age, gender, ASA score, body mass index (BMI) (P>0.05). There were no significant differences among the groups in terms of average operative time, blood loss, time to liquid diet, time to hospital stay(P>0.05). There were no significant differences between the two groups for postoperative pain scores [2.8 (1-5) vs 3.3 (2-6),P>0.05]. Significant differences were observed for cosmesis satisfaction scores between the two groups [9.58 (9-10) vs 8.60 (8-9),P<0.05]. There were also no significant differences in the conversion rate between the experimental group and the control group (2.5% vs 0%, P>0.05). Conclusion〓SILA in obese patients with acute appendicitis is safe and feasible, and is better in cosmesis satisfaction scores than SLA.
