Survey on the plastic biliary stent in the management of large or multiple common bile duct stone

Abstract

Abstract Introduction: One of the common treatments for patients with multiple or large gallstones is ERCP and biliary stent placement. In some of these patients, the biliary stent loses its function. Therefore, we designed this study to identify practical factors in treatment failure with the plastic biliary stent. Methods: This cross-sectional study was conducted during 2018-2019 on patients undergoing ERCP in Rouhani Babol Hospital. The information was obtained before the procedure, and the patients were monitored in the hospital for 24 hours afterward. After discharge, they were followed up twice (6-8 weeks and 12-16 weeks later) to check the need for ERCP and possible complications. Results: Among the 70 examined patients, the success rate of the plastic biliary stent was 88.6 percent. Stent failure was more in patients with larger stone sizes (P=0.001) and longer duration of ERCP (P=0.04). In regression analysis, body mass index (BMI) (P=0.02) and stone size (P=0.04) were identified as risk factors for the probability of stenting failure. Conclusion: According to the results of this study, the common bile duct stenting method has a high success rate. Also, the plastic biliary stent failed more in patients with larger stone sizes and high BMI.
