[Effectiveness of endoscopic ultrasound-guided biliary drainage in patients experiencing obstructive jaundice due to unsuccessful endoscopic retrograde cholangiopancreatography].

Objective: To assess the treatment outcomes of endoscopic ultrasound-guided biliary drainage (EUS-BD) in patients with obstructive jaundice due to unsuccessful endoscopic retrograde cholangiopancreatography (ERCP). Methods: The clinical data of patients with obstructive jaundice who underwent EUS-BD due to ERCP failure at the Gastrointestinal Endoscopy Center of Beijing Friendship Hospital from September 2018 to November 2023, was retrospectively collected and analyzed. We explored the technical success, clinical success, and adverse events associated with EUS-BD. Results: In total, 43 EUS-BD procedures were performed in 39 patients with a technical success rate of 86.0% (37/43). The clinical success rate was 81.1% (30/37). Biliary drainage was not effectively achieved in seven cases, including two fatal cases and five cases of recurrent postoperative biliary obstruction. The incidence of adverse events was 21.6% (8/37), including two cases of postoperative bile leakage peritonitis, two cases of stent displacement, one case of stent dislocation, one case of perforation, and two cases of death. Conclusion: EUS-BD is a relatively safe and effective method for bile duct drainage, serving as a dependable alternative therapeutic option for patients with obstructive jaundice due to unsuccessful ERCP.
