Endoscopic stenting for malignant biliary obstruction is technically successful in patients with preexisting duodenal stents

Abstract: Background and study aims There are limited data on the success of endoscopic retrograde cholangiopancreatography (ERCP) in patients with malignant biliary and duodenal obstruction with a preexisting duodenal stent. The aim of this study was to evaluate patient and procedural outcomes of a cohort of patients with preexisting duodenal stents who underwent an attempt at ERCP for malignant biliary obstruction (MBO). Patients and methods This was a single-center retrospective study on consecutive patients with a preexisting duodenal stent who underwent attempted ERCP for MBO. Technical success was defined as successful cannulation of the common bile duct, with successful dilation and/or deployment of a biliary stent under fluoroscopy. Clinical success was defined as number of patients in the entire group who underwent ERCP successfully with resolution of symptoms. Results We identified 64 patients (73 % men, 74 % white, median age 62 years) with a preexisting duodenal stent who underwent 85 attempts at ERCP. ERCP was technically successful in 50 of 85 procedures (59 %). Overall ERCP was successful in 41 of 85 patients (48 %). ERCP was more likely to be successful in patients with Type 1 and 3 duodenal strictures than with Type 2 strictures (83 % and 92 % vs. 42 %, P < 0.01), in patients with a preexisting sphincterotomy (79% vs. 20 %, P = 0.01) or preexisting biliary stent (66 % vs. 34 %, P = 0.04). Adverse events included bleeding (n = 3), post-procedure fever (n = 3) and abdominal pain (n = 1). Conclusions Although biliary stenting via ERCP is often technically challenging in patients with a prior duodenal stent, it is a safe and effective method of biliary drainage. ERCP should be attempted in patients with Type 1 and 3 duodenal strictures, a prior sphincterotomy or an indwelling biliary stent.
