Objective: To summarize the clinical experience of transumbilical single-port laparoscopic cholecystectomy, and evaluate its clinical utility and the feasibility of widely usage. Methods: Between April 2012 and June 2017, 500 cases who underwent transumbilical single-port laparoscopic cholecystectomy with totally free umbilical ring by conventional instruments were enrolled. The clinical data were retrospectively analyzed. Results: A total of 487 patients were successfully completed the operation. In addition, 3 cases were converted to open cholecystectomy, 10 cases were converted to multi-port laparoscopy and drainage tubes were placed in 5 cases. The mean operating time of transumbilical single-port laparoscopic cholecystectomy(from the Trocars being put to the gallbladders being removed)shortened from 72.3 min to 13.2 min. The average bleeding amount was less than 10 ml. After the operation, 3 cases had delayed bile leakage and 3 cases had transient up-regulation of bilirubin at the beginning of the technique. No patients had hemorrhage and Trocar hernia. The average hospital stay of patients was 2.1 days. The cosmetic effect was remarkable during follow-up. Conclusion: The transumbilical single-port laparoscopic cholecystectomy with totally free umbilical ring by conventional instruments should be widely carried out in hospitals at all levels because of its minimal postoperative pain, rapid recovery, hidden incision, low costs and low incidence of port-site hernia.
