Abstract    Objective    To explore the security and feasibility of the transumbilical single port needle-laparoscopic cholecystectomy (TUSPLC). Methods    The clinical data of 326 patients performed TUSPLC used by needle laparoscopic and curved apparatus from February to October 2010 at Chinese People’s Liberation Army 451 Hospital were analyzed retrospectively．Results    Among 326 patients, 301 patients were performed TUSPLC successfully with no operation complication occurred, such as jaundice, hemorrhage and wound infection, etc. The mean operation time was 35.5min. The mean blood loss was 17.2mL. Other 24 patients were transferred to 3 or 4 port LC because of adherence, inflammation, anatomy variation, large wound area in Calot's triangle and necessary drainage. Effusion in the fossa of gallbladder within 4 days after operation happened in one patient who were treated well with laparoscopic exploration and drainage. All patients were followed up from 2 weeks to 3 months. The scars were so small and hidden in the fovea umbilicalis that there were not obviously visible scars on abdominal wall. Conclusion    Operators should deal with the surgical indications carefully before and in the operations. TUSPLC is safe and has the aesthetic advantage obviously.
