ABSTRACT
AIM: Incidence of common bile duct stones (CBDS) is approximately 10% in patients with symptomatic gallstones undergoing laparoscopic cholecystectomy. Transcystic laparoscopic common bile duct exploration (TC-CBDE) is safe and efficient in achieving bile duct clearance from stones, with a success rate of between 85% and 95%. The aim of this retrospective study is the evaluation of risk factors and recurrence in patients treated with TC-CBDS. METHODS: From October 2003 until September 2007, 110 consecutive patients with common bile duct stones and gallbladder were included in the study. Average age was 64 years (range 21-82 years). The procedure was completed laparoscopically in 106 patients (96.4%): with TC-CBDE in 90 patients (85%), who are the object of this study; and with TC-CBDE + perioperative guide wire papillotomy ("rendezvous") in 16 cases (15%). In the 90 patients treated with TC-CBDE which we examined, the risk factors were: preoperative liver function tests, diameter of the common bile duct (normal 8 mm or less), number of stones (
