Introduction: ERCP has become the standard treatment for common bile duct (MBD) stones. Its effectiveness can exceed 90% of the cases. However, the diameter and number of stones represent a difficulty for ERCP, which limits its effectiveness. The purpose of our work is to study the success rate of ERCP in the treatment of primary bile duct stones and to establish the frequency and possible risk factors for complications. Materials and methods: 208 patients were included from May 2015 to August 2018. 2 groups were studied: Group I (n = 128): patients with less than 3 gallstones and the largest diameter was less than 15 mm, while group II (n = 80) represented those with multiple stones (> 3) or large gallstones (≥15mm). We compared the results of ERCP and the correlated factors of complications between two groups. We used the chi-square test and Fisher's test for the study with p <0.05. Results: The success rate in a single catheterization was 92.2% in group I versus 74% (59/80) in group II (p = 0.01). The overall success rate after complementary technique and / or secondary maneuvers was 93.7% in group 1 versus 80.7% in group 2 (p = 0.02). The overall rate success was 90 % in our study. The short-term complication rate was 7% (9/128) in group 1 versus 11.25% (9/80) in group 2 (p = 0.21). The complication risk factor was Wirsung's cannulation for pancreatitis (p = 0.02) and haemorrhage precut (p = 0.03). The study did not show a significant difference in complications between the two groups (p = 0.21). Conclusion: ERCP is the standard treatment for choledocholithiasis disease. In our study, the success rate was 90% with a complication rate of 9.6%, which corresponds to the literature. The size and number of gallstones have an impact on the success rate but not on the complications.
