Single-session double-stent placement in concomitant malignant biliary and duodenal obstruction with a cautery-tipped lumen apposing metal stent.

Endoscopic palliation of concomitant biliary and duodenal malignant obstruction can be challenging because of difficult access to the papilla, which may consequently result in possible failure of endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic ultrasonography-guided biliary drainage (EUS-BD), either before or after duodenal stent placement, has emerged as an alternative approach in these cases. A novel cautery-tipped lumen apposing metal stent (LAMS; Hot-AXIOS, Boston Scientific Corp., Natick, Massachusetts, USA) has recently been developed for this purpose [1–3]. In this case series, we describe a new approach for the palliation of patients presenting with simultaneous duodenal and biliary obstruction based on the single-session sequential deployment of this novel cautery-tipped LAMS and a duodenal stent in patients with unreachable papilla or failed ERCP. Four patients with unresectable pancreatic cancer (three men, one woman; mean age 63±18) and one man aged 53 with a duodenal adenocarcinoma were treated. Biliary drainage was obtained by placing the LAMS by the transbulbar approach under EUS guidance in a fluoroless and wireless manner (●" Fig.1 and ●" Fig.2a; ●" Video1). A duodenal self-expanding metal stent (SEMS; WallFlex Enteral, BosFig.3 Final correct positioning of the duodenal self-expanding metal stent (SEMS) and biliary lumen apposing metal stent (LAMS) is shown: a fluoroscopically; b on endoscopic view.
