Application of magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography in biliary obstruction

Introduction: Biliary obstruction is a common clinical disease, and magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) play an important role in the diagnosis and treatment of biliary obstruction. This study explores the localization, qualitative diagnosis, and treatment effects of MRCP and ERCP on biliary obstruction diseases. Methods: Retrospective analysis of patients diagnosed with biliary obstruction who underwent MRCP examination and ERCP treatment from October 2022 to October 2024. The patients were divided into jaundice group and non-jaundice group according to their clinical characteristics. The clinical characteristics, treatment, and accuracy of localization and qualitative diagnosis of the two groups were analyzed. Results: A total of 78 patients with biliary obstruction who underwent MRCP examination and ERCP treatment were collected, with 39 cases in jaundice group and 39 cases in the non-jaundice group. The total bilirubin level and alkaline phosphatase (ALT) level in the jaundice group were significantly lower than those before surgery, with significant differences. In terms of localization and qualitative diagnosis in both the jaundice group and non-jaundice group, the results indicate that the combination of MRCP and ERCP has a high accuracy rate for the localization and qualitative diagnosis of biliary obstruction. Conclusion: In the diagnosis of biliary obstruction diseases, MRCP and ERCP have their own advantages and disadvantages. By combining the strengths of both, accuracy of localization and qualitative diagnosis of biliary obstruction can be improved to some extent. In terms of treatment, the bilirubin and ALT levels in the jaundice group improved significantly after ERCP, indicating that ERCP is more effective in patients with biliary obstruction complicated with jaundice.
