Introduction: lithiasis of the main bile duct is one of the main indications for endoscopic retrograde cholangiopancreatography (ERCP). This procedure can remove stones using a minimally invasive procedure. Objective: to determine the usefulness of cholangiopancreatography in the treatment of choledocholithiasis. Methods: a retrospective and descriptive study of the results of cholangiopancreatography performed in patients with lithiasis of the main bile duct from 2009 and 2010. The sample was 31 patients. Percentages, mean and standard deviation were used to compile the information. Technical procedures were performed to determine the predictive ability of ultrasound and alkaline phosphatase in the diagnosis of choledocholithiasis. Results: most patients were female. A high percentage were older than 60 years and some were older than 90. Stone removal was achieved in 60.8 %. The ultrasound showed 51.61 % of sensitivity (95 % CI 32.41 to 70.82) and 88.98 % of specificity (CI 83.14 to 94.82) for the diagnosis of urolithiasis. Alkaline phosphatase showed no diagnostic accuracy (AUC = 0.501). Conclusions: results support the utility of endoscopic retrograde cholangiopancreatography for choledocholithiasis treatment. The predictive ability of ultrasound and alkaline phosphatase was low, if compared with the results of this procedure.
