The utility of self-expanding metal stents in benign biliary strictures: A retrospective case series

Abstract

Background: Benign biliary strictures are a diverse clinical challenge stemming from various etiologies. The utility of self-expanding metal stents (SEMS) in their management has gained attention, yet comprehensive assessments of SEMS in this context remain essential. Objectives: The basic aim of the study is to find the utility of self-expanding metal stents in benign biliary strictures. Material and methods: A retrospective case series was conducted at DHQ Teaching Hospital Gujranwala, encompassing 104 patients with benign biliary strictures from June 2022 to June 2023. Data collection included patient demographics, etiology of strictures, SEMS placement details, and follow-up outcomes. Inclusion and exclusion criteria were strictly adhered to, ensuring data quality. Results: The study cohort demonstrated a diverse etiology, with postoperative complications (62.5%) being the most common. Technical success was achieved in 96.2% of cases, while clinical success was observed in 94.2%. Stent patency was maintained in 90% of patients during the one-year follow-up. Recurrent symptoms and complications were infrequent, occurring in 9.6% and 8.7% of cases, respectively. Follow-up duration varied, and concurrent interventions were associated with improved clinical outcomes in some cases. Conclusion: It is concluded that SEMS represent a safe and effective therapeutic modality for the management of benign biliary strictures. These findings provide clinicians with evidence-based support for the use of SEMS in this specific patient population, emphasizing the procedure's ability to relieve symptoms, restore biliary patency, and enhance overall patient well-being.
