Introduction: Bile duct stones is the presence of calculi in the common bile duct caused by its migration from the gallbladder or its extrahepatic or intrahepatic formation in the bile duct. Objective: Determine the surgical conduct adopted for BDS treatment not removed by ERCP. Materials and methods: Observational, retrospective, descriptive, cross-section study. Results: From the studied patients, calculi were found in 62% of the performed ERCP, in which the symptoms were resolved 85% of the times (151/245). The average age was of 56.3 ± 20.75 years old with a female predisposition of 78%. In the remaining patients, the most used surgical techniques were open surgery (22/23) and choledochotomy, more frequently with primary closure (14/23). Only a single case was resolved by laparoscopy. Conclusion: open method and choledochotomy with primary closure are the main surgical techniques used.
