Five-Year Experience with Transcystic Laparoscopic Common Bile Duct Exploration.

Background: Common bile duct (CBD) stones associated with cholecystitis can be treated by single-stage CBD exploration at the time of cholecystectomy or a two-stage approach with endoscopic stone extraction before or after cholecystectomy. The ideal management remains a matter of debate. The aim of this study is to analyze our outcomes with transcystic laparoscopic common bile duct exploration (LCBDE). Material and Methods: A retrospective review of patients who underwent transcystic LCBDE between 2015 and 2019 was performed. Results: A total of 106 patients underwent transcystic LCBDE over 5 years. We performed 1192 laparoscopic cholecystectomies with cholangiograms from March 2015 to December 2019. Fifteen patients had a preoperative endoscopic retrograde cholangiopancreatography (ERCP) for CBD stones seen on magnetic resonance cholangiopancreatography that during laparoscopic cholecystectomy with intraoperative cholangiogram (IOC), there were stones and/or sludge found in the CBD, which required clearance through a transcystic approach. Of the 91 patients who did not have a preoperative ERCP, clearance of the CBD was successful through a transcystic approach in 78 patients (86%). In the 13 patients that intraoperative clearance was not achieved (n = 13, 14%), a postoperative ERCP was performed. A total of 28 patients underwent either pre- or postoperative ERCP (n = 28, 26%). Choledochotomy was not performed in any of the patients. The mean operative time was 127 minutes (127 ± 48). The mean hospital length of stay (LOS) was 4 days (3.9 ± 2.8) with a median LOS of 3 days. Complications observed include wound infection (n = 2, 2%), pancreatitis after ERCP (n = 1, 1%), pneumonia (n = 1, 1%), and right hepatic duct injury (n = 1, 1%). Conclusion: Transcystic LCBDE is an effective and safe option for treatment of CBD stones. While a transcystic approach does not guarantee clearance of the CBD, it avoids the morbidity associated with a choledochotomy and can often prevent patients from having to undergo an additional procedure.
