This study determined the incidence of unsuspected choledocholithiasis in a population deemed to be low risk undergoing laparoscopic cholecystectomy with routine intra‐operative cholangiography. In addition to this, the management of these patients was reported along with predictive factors for an abnormal intra‐operative cholangiogram were determined. Risk factors independently associated with unsuspected choledocholithiasis included patients over the age of 55 years of age (odds ratio 2.93, P = 0.038) and a large cystic duct size (odds ratio 3.13, P < 0.001) on multivariable analysis.
