: Endoscopic biliary plastic stenting is a safe and effective temporary therapeutic modality used in various benign biliary disorders. Long-term indwelling stents for more than one year without retrieval are termed "forgotten biliary stents". In clinical practice, the forgotten stents are underestimated and the majority of data were obtained from case reports. The aim of this study was to determine the forgotten-biliary-plastic-stent-related complications, their management, and the patients' clinical outcomes. : This retrospective study was performed at three hospitals during the period from January 2021 to December 2023. In total, 577 patients with biliary plastic stents-inserted for a variety of benign biliary conditions-were included. They were divided into two groups, as follows: group 1 included 527 patients who had biliary stents removed within 3 months, and group 2 included 50 patients with biliary stents retrieved after one year of their deployment. The stent-related complications (e.g., acute cholangitis, stent clogging, distal stent migration, new common bile duct (CBD) stone formation, and proximal stent migration) and the endoscopic management success rate were evaluated. : Irretrievable CBD stones were the main indication for biliary plastic stenting in both groups. The stent-related complications, number of endoscopic sessions, and hospital admissions were significantly higher in the patients with forgotten biliary stents than those with stent removal within 3 months. All the study patients were successfully managed endoscopically with uneventful outcomes. : Based on this retrospective study, non-adherence to the endoscopists' instructions is the main reason for retained biliary stents for more than one year. The patients with forgotten stents had significantly higher complication rates, a higher number of endoscopic sessions, and a higher number of hospital admissions than those with stents that were retrieved in the scheduled time. All patients were managed endoscopically with a technical success rate of 100%, and with no complication-related mortality.
: 经内镜胆道塑料支架置入术是一种安全有效的临时治疗方法，适用于各种良性胆道疾病。留置时间超过 1 年的长期支架被称为“遗忘性胆道支架”。在临床实践中，人们低估了遗忘性支架的存在，并且大多数数据都来自病例报告。本研究旨在确定遗忘性胆道塑料支架相关并发症、其处理方法以及患者的临床结局。: 本回顾性研究于 2021 年 1 月至 2023 年 12 月在三家医院进行。共纳入 577 例因各种良性胆道疾病而置入胆道塑料支架的患者。他们被分为两组：第 1 组包括 527 例在 3 个月内取出胆道支架的患者，第 2 组包括 50 例支架置入 1 年后取出的患者。评估了支架相关并发症（如急性胆管炎、支架堵塞、远端支架迁移、新的胆总管（CBD）结石形成和近端支架迁移）和内镜处理成功率。: CBD 不可回收结石是两组患者置入胆道塑料支架的主要指征。与 3 个月内取出支架的患者相比，遗忘性胆道支架患者的支架相关并发症、内镜治疗次数和住院次数明显更高。所有研究患者均经内镜成功治疗，无不良结局。: 基于本回顾性研究，不遵守内镜医生的指示是导致支架留置超过 1 年的主要原因。与按时取出支架的患者相比，遗忘性支架患者的并发症发生率更高，内镜治疗次数和住院次数更多。所有患者均经内镜成功治疗，技术成功率为 100%，无并发症相关死亡率。
