T-tube-free single-incision laparoscopic common bile duct exploration plus cholecystectomy: a single centre experience: T-tube-free SILCBDE plus cholecystectomy

BACKGROUND: The present study aimed to explore the indications and feasibility of T-tube-free trans-umbilical single-incision laparoscopic common bile duct exploration (SILCBDE) plus laparoscopic cholecystectomy (LC) for treating choledocholithiasis. METHODS: Patients hospitalized in the Second Affiliated Hospital (Shengjing Hospital) of China Medical University from January 2010 to January 2017 with the diagnosis of common bile duct stones and treated with T-tube-free trans-umbilical single-incision LC plus common bile duct exploration were retrospectively analysed. RESULTS: A total of 37 male/female choledocholithiasis patients (mean age 65 years, range 29-86) were treated with T-tube-free trans-umbilical SILCBDE plus LC. No intraoperative complication or conversion to open surgery occurred in any of the cases. The mean operative time was 99.8 min (range 84-125) for endoscopic nasobiliary drainage group (n = 6), 113.8 min (range 70-150) for endoscopic retrogradebiliary drainage group (n = 2), 131.1 min (range 75-161) for pigtail J-tube group (n = 24), 113.7 min (range 100-150) for primary closure group (n = 5). The mean post-operative hospital stay length was 5.5 days (range 4-7) for endoscopic nasobiliary drainage group, 12.5 days (range 10-15) for endoscopic retrogradebiliary drainage group, 6.5 days (range 4-10) for J-tube group, 5.8 days (range 4-9) for primary closure group. Pancreatitis, bile leakage and peritonitis were not presented in any of the group. After 17-101 months follow-up, three patients presented recurrent common bile duct stones. CONCLUSION: In selected cases, T-tube-free trans-umbilical SILCBDE plus LC is feasible and safe for experienced surgeons, and can achieve similar therapeutic effects as common LC plus common bile duct exploration procedures.
