BACKGROUND: Intraoperative cholangiography (IOC) has been historically used to detect common bile duct (CBD) stones, delineate biliary anatomy, and avoid or promptly diagnose bile duct injuries (BDIs) during laparoscopic cholecystectomy (LC). We aimed to determine the usefulness of routine IOC during LC in an urban teaching hospital.
METHODS: A consecutive series of patients undergoing LC with routine IOC from 2016 to 2018 was prospectively analyzed. Primary outcomes of interest were: CBD stones, BDI, and anatomical variations of the biliary tract. Secondary outcomes of interest were: IOC success rate, IOC time, and readmission for residual lithiasis. A comparative analysis was performed between patients with and without preoperative suspicion of CBD stones.
RESULTS: A total of 1003 LC were analyzed; IOC was successful in 918 (91.5%) patients. Mean IOC time was 10 (4 to 30) minutes. Mean radiation received by the surgeon per procedure was 0.06 millisieverts (mSv). Normal IOC was found in 856 (93.2%) patients. CBD stones and aberrant biliary anatomy were present in 58 (6.3%) and 4 (0.4%) cases, respectively. Two patients (0.2%) underwent unnecessary CBD exploration because of false-positive IOC. Four patients (0.4%) with normal IOC were readmitted for residual CBD stones. Five (0.5%) minor BDI undetected by the IOC were diagnosed. Patients with preoperative suspicion of CBD stones had significantly higher rates of CBD stones detected on IOC as compared with those without suspicion (23.2% vs. 2.1%, P<0.0001).
CONCLUSION: Routine use of IOC resulted in low rates of BDI diagnosis, aberrant biliary anatomy identification and/or CBD stones detection. Selection of patients for IOC, rather than routine use of IOC appears a more reasonable approach.
