A 71-year-old woman with a history of Roux-en-Y gastric bypass and recently diagnosed metastatic pancreatic head adenocarcinoma presented for a repeat single-balloon enteroscopy-assisted endoscopic retrograde cholangiography (SBE-ERC) for stent exchange for worsening jaundice. Three 7Fr double-pigtail plastic stents were placed during her last procedure (Figure 1A). SBE-ERC was performed using the Olympus SBE system (SIF-Q180, Olympus America, with a 2.8 mm diameter instrument channel).
