Management of impacted common bile duct stones during a laparoscopic procedure: A Retrospective Cohort Study of 377 Consecutive Patients.

INTRODUCTION: To explore the techniques for managing impacted common bile duct (CBD) stones during laparoscopic common bile duct exploration (LCBDE).

METHODS: We retrospectively analyzed 377 consecutive patients undergoing LCBDE from January 2008 to June 2015. Group 1 was defined as patients with impacted CBD stones. Group 2 included patients without impacted CBD stones. The outcomes of LCBDE were compared between the two groups.

RESULTS: There were 65 patients in Group 1 and 312 patients in Group 2. The incidence of jaundice, abnormal liver function tests, cholangitis and pancreatitis was higher in Group 1. Forty-one patients with small impacted CBD stones were managed using the tipless Nitinol basket. Seventeen patients with large impacted CBD stones and 7 patients with small impacted CBD stones underwent laser lithotripsy via choledochoscopy. None of the patients in Group 1 was converted to open procedures for impacted CBD stones. Operation duration was 13.6 min longer in Group 1 (133.2 min). Postoperative hospital stay was significantly longer in Group 1 (9.7 ± 2.5 d) than in Group 2 (6.3 ± 1.8 d). There was no difference in the overall postoperative complication rate, retained stone rate, and recurrence rate between the two groups.

CONCLUSION: Rational utilization of laser lithotripsy and an appropriate basket in LCBDE may avoid conversion to open procedures in patients with impacted CBD stones.
