Background and objective  Laparoscopic cholecystectomy is used for the treatment of symptomatic gallstones. Intraoperative cholangiogram (IOC) is used to diagnose common bile duct (CBD) stones. There is controversy surrounding routine vs selective use of IOC based on clinical, biochemical and ultrasound criteria. The aim of this study was to evaluate the outcomes from routine IOC and its utility in laparoscopic cholecystectomy.  Materials and methods  This was a UK-based single-centre retrospective study evaluating the outcomes from IOC for all laparoscopic cholecystectomies performed between May 2014 and February 2020. All adult patients undergoing elective, semi-elective or emergency operations were included. Demographics, biochemistry as well as radiological and endoscopic investigations were analysed. IOC was performed using a standardised technique and was interpreted by a single surgeon.  Results  A total of 744 out of 804 patients underwent IOC. The median age of the cohort was 51 years (SD: ±17.5); there were 468 females (62.9%) and 276 males (37.1%). Filling defects were identified in 43/744 (5.8%) patients, with 23/43 having stone extraction via endoscopic retrograde cholangiopancreatography (ERCP). Logistic regression analysis identified alkaline phosphatase (ALP) as a predictor of filling defects in IOC (OR: 1.003; 95% CI: 1.001-1.005, p=0.015).  Conclusion  Based on our findings, the routine use of IOC during laparoscopic cholecystectomy is safe and effective. Preoperative clinical, radiological and biochemical parameters apart from ALP have a limited role in predicting the diagnostic yield of IOC.
