Abstract
پBackground: One of the common treatments for patients with multiple or large gallstones is ERCP and plastic biliary stent placement. In this study, we aim to identify plastic biliary stent efficacy and potential factors in treatment failure in patients with multiple or large gallstones.
Methods: This cross-sectional study was conducted during 2018-2019 on patients undergoing ERCP in Rouhani Babol Hospital. The patient records were obtained before the procedure, and the patients were monitored in the hospital for 24 hours afterwards. After discharge, they were followed up twice (6-8 weeks and 12-16 weeks later) to reassess the indication for ERCP and possible complications.
Results: Among the 70 studied patients, the success rate of the plastic biliary stent was 88.6 percent. Stent failure was more common in patients with larger stone sizes (20.50 ± 1.29 vs 14.57 ± 3.63 millimeters, p=0.001) and longer duration of ERCP (16.25 ± 6.29 vs 9.70 ± 5.73 minutes, p=0.04). In multivariate logistic regression analysis, body mass index (BMI) (OR: 1.84, 95% CI: 1.06-3.17, p=0.02) and stone size (OR: 2.32, 95% CI: 1.01-5.32, p=0.04) were identified as risk factors for stenting failure.
Conclusion: According to the results of this study, the common bile duct stenting using plastic biliary stent has a high success rate. Also, the plastic biliary stent failure was more common in patients with larger stone sizes and higher BMI.
