Index admission vs elective laparoscopic common bile duct exploration: a district general hospital experience over 6 years.

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) is relatively a new approach for clearing choledocholithiasis. The aim of this study is to assess the safety of this approach to clearing common bile duct (CBD) stones on an index admission including emergency setting.

METHODS

Retrospective data collection and analysis were carried out for 207 consecutive cases of LCBDE performed in Royal Cornwall Hospital over 6 years (2015-2020). Patients were divided into two groups (Index admission vs elective) then both groups compared.

RESULTS

A total of 207 cases of LCBDE were performed in our unit during the time period. One hundred twenty-two operations were performed on the index admission and 85 on a subsequent elective list. Mean operative time was 146 ± 64 min in the index admission group and 145 ± 65 min in the elective group (p = 0.913). Length of stay post-operatively was 3.3 ± 6.3 days in the index admission cases and 3.5 ± 4.6 days after elective cases. Successful clearance was achieved at the end of the operation in 116 patients in the index admission group, clearance failed in one case and negative exploration in 5 patients. In the elective group 83 patients had a successful clearance at the end of the operation, and 2 patients has had a negative exploration. Twelve patients (index admission group) and 8 patients of the elective cases required post-operative Endoscopic Retrograde Cholangiopancreatography (ERCP) to manage retained stones, recurrent stones and bile leak (p = 0.921). Three patients required re-operation for post-operative complications in each group.

CONCLUSION

Common bile duct exploration in index admission is safe with high success rate if performed by well-trained surgeons with advanced laparoscopic skills.
