Abstract    Objective    To evaluate the outcomes of transumbilical single-port laparoscopic cholecystectomy and review the technique improvement. Methods    From May 2008 to Dec 2009, 120 cases transumbilical single-port laparoscopic cholecystectomy were performed in our hospital. The clinical data and surgical outcomes were retrospectively reviewed. Results    One patient (0.8%) was converted to traditional laparoscopic cholecystectomy (4 ports) due to perigallbladder adhesion. The mean operating time was 58.5±23.7min (28-145min). The mean blood loss was 15.3±8.6ml (2-100ml). The mean postoperative hospital stay was 1.3 (range, 1-3d) days. All the incisions except 4 were healed well and the surgical scar was satisfied and virtually concealed within the umbilicus. No postoperative complications were observed at follow-up 1-17 months. Conclusions    Transumbilical single-port laparoscopic cholecystectomy is feasible when patients were well selected.
