Objective: To investigate the feasibility of transumbilical single-port laparoscopic cholecystectomy (TUSPLC) through improved electric hook access. Methods: The clinical data of 517 patients undergoing TUSPLC by improved electric hook access from August 2009 to February 2013 were retrospectively analyzed. Results: Two patients were converted to open surgery due to severe adhesions of the gallbladder to neighboring tissues and Mirizzi’s syndrome, respectively. For the entire group, the operative time was 22–55 min, intraoperative blood loss was 10–30 mL, and the length of postoperative hospital stay was 1–2 d. No serious complications such as bile leakage, hemorrhage bile duct injury occurred. Follow-up was conducted in 428 patients for 1–18 months, during which no long-term complications or discomfort were noted in the patients; all scars were almost invisible, and the cosmetic results were satisfactory. Conclusion: TUSPLC using conventional laparoscopic instruments through improved electric hook access is feasible and safe, and also easy to implement in practice.
