Background And Objectives:
The use of routine versus selective intra-operative cholangiogram (IOC) for laparoscopic cholecystectomy (LC) remains an area of debate. In this study, we investigated the routine use of IOC in a single center, to determine whether it confers a reduced risk of common bile duct (CBD) injury and improved patient outcomes. We also identified several preoperative predictive factors for CBD stone detection on IOC to investigate the feasibility of a predictive model.
Methods:
We identified 1005 LCs with routine IOC over a 2-year period at the Norfolk and Norwich University Hospital from October 1, 2013, to September 30, 2015. Outcomes measured included CBD stone detection on IOC, CBD injury, complication rates, readmission rate, and mortality. We also calculated sensitivity, specificity, and likelihood ratios for detection of CBD stones on IOC from preoperative biochemistry and radiological investigations.
Results:
We identified a CBD stone detection rate of 10.1% and a readmission rate of 0.03%, with no reported CBD injuries and 1 reported mortality. Of the preoperative predictive factors investigated, the most specific for CBD stone detection on IOC was bilirubin at 89%. The most sensitive was preoperative MRCP at 77%.
Discussion:
This study demonstrates that routine IOC is an effective method of detecting CBD stones and CBD injuries, resulting in improved patient outcomes and economic benefits for health services. We have also identified several predictive factors for CBD stones on IOC.
