Advanced endoscopic rescue after failed endoscopic ultrasound-guided choledochoduodenostomy

EUS-guided choledochoduodenostomy (EUS-CDS) has become an established alternative to percutaneous or surgical approaches in cases of failed or predicted difficult ERCP.

We report a case of complex endoscopic management of biliary obstruction in a 46-year-old woman with inoperable pancreatic adenocarcinoma. Because of tumor-related deformation of the papillary region, primary transpapillary drainage was not feasible.

EUS-CDS using a 6- × 8-mm electrocautery-enhanced lumen-apposing metal stent (LAMS) (Hot AXIOS stent; Boston Scientific, Marlborough, Mass, USA) was performed. Misdeployment of the distal flange led to bile leakage and stent dysfunction. Subsequent placement of a fully covered self-expandable metal stent (8 mm × 6 cm) (BONASTENT; MTW, Wesel, Germany) resulted in secondary stent dislocation into the paraduodenal space. The dislocated stent was successfully retrieved endoscopically through the original access using a 3-mm cholangioscope (Scivita, Boston Scientific). The duodenal defect was closed with 2 closure clips (MANTIS Clip, Boston Scientific). The patient recovered uneventfully and remained asymptomatic at 2-month follow-up.

This case illustrates the feasibility of endoscopic rescue in a challenging scenario after LAMS misdeployment using advanced ERCP and closure techniques.
