Summary

Endoscopic retrograde cholangiopancreatography (ERCP) is the primary therapeutic procedure for many bilio-pancreatic diseases, and requires the first crucial step of the successful deep cannulation of the common bile duct through the Vater's papilla. Difficult biliary cannulation (DBC) is a well-recognized risk factor for adverse events (AE) and cannulation failure, which has been reported in about 11% of ERCP regardless of their indication and a relevant heterogeneity in definition of DBC is present in the available studies. More recently, DBC during ERCP has been precisely defined by the European Society of Gastrointestinal Endoscopy (ESGE) as follows: more than 5 contacts with the papilla whilst attempting to cannulate; more than 5 minutes spent attempting to cannulate after visualization of the papilla; more than one unintended pancreatic duct cannulation or opacification (4). To date, the rate of DBC has not been calculated for specific sub-groups of ERCP indications. In particular, the rate of DBC in the setting of distal malignant biliary obstruction (DMBO), a frequent indication for ERCP, has not yet been described. DMBO is generally secondary to pancreatic adenocarcinoma, distal cholangiocarcinoma, ampullary carcinomas or adenopathy/metastasis from other cancers, and could potentially increase the complexity of the procedure as the tumor compression or infiltration alter the normal duodenal/papillary anatomy or determine duodenal rigidity.

In this study, we aimed to investigate the rate of DBC and the outcome of patients undergoing ERCP for DMBO.
