Safety and effectiveness of consecutive 191 endoscopic ultrasonography-guided biliary drainage procedures: a single-center experience

Le résumé fourni par la source

Introduction: The development of endoscopic ultrasonography (EUS) has enabled extra-anatomical transmural access to the bile ducts, thus making it possible to perform endoscopic biliary anastomoses with the gastrointestinal (GI) tract and obtain extra-anatomical transpapillary access. EUS provides an alternative to the existing methods of biliary drainage (BD) for cases in which endoscopic retrograde cholangiopancreatography (ERCP) is ineffective.Aim: This study aimed to evaluate the efficacy and safety of extraanatomical endoscopic biliary access methods for the treatment of benign and malignant biliary strictures.Material and methods: This retrospective analysis included treatment results of all patients with obstructive jaundice and biliary strictures who were treated endoscopically in our department between 2016 and 2023. The study group comprised patients in whom EUS-guided transmural access was used during ERCP because of biliary strictures and the lack of transpapillary access.Results: Twenty-eight patients (14.66%) underwent endoscopic transpapillary biliary stenting via a transmural approach under EUS guidance. The remaining 163 patients (85.34%) underwent extraanatomical transmural biliodigestive anastomosis. Technical success was achieved in 186 of 191 (97.38%) patients. Clinical success was achieved in 170 of 191 (89.01%) patients. Complications were reported for 32 of 191 (16.75%) patients, including fatal complications for 6 of 191 (3.14%) patients.Conclusions: Advanced endoscopic techniques involving EUS-guided transmural access are effective and safe for biliary strictures. They provide an alternative to other drainage techniques when ERCP is ineffective and improve the quality of life of patients undergoing palliative treatment for biliary strictures with unresectable cancer of the biliopancreatic area.
