Abstract    Objective    To evaluate the application of laparoendoscopic single-site surgery (LESS) in general surgery and summarize initial experience. Methods    The clinical data of 102 adult patients performed LESS from August 2008 to August 2010 at Nankai Hospital of Tianjin City were analyzed retrospectively. Results    In 102 patients, 51 patients were performed LESS appendectomy and 9 of them were converted to srandard laparoscopic appendectomy because of severe adhesion（transfer rate 17.65%）. LESS cholecystectomy was performed in 39 patients and 5 of them were converted to four-port laparoscopic cholecystectomy because of exposing clot’s tri-angle difficultly（transfer rate 10.20%）. Three patients were performed LESS cholecystectomy and liver cyst fenestration. Nine patients received combined LESS cholecystectomy and appendectomy. One patient was found common bile duct stone postoperatively and was cured by endoscopic stone extraction. Two patients had gallbladder bed infection and were cured by abdominal paracentesis. There was no wound infection, bile duct injury and bleeding found. In followed-up of 4-24 months, no intestinal obstruction, umbilical hernia, appendix stump inflammation, bile duct stenosis and other complications appeared. Conclusion    LESS is safe and feasible, minimally invasive and cosmetic. But the surgical procedures are more difficult than traditional laparoscopic surgery. The operative indications should be controled carefully and it should be performed by experienced laparoscopic surgeons.
