Background Current studies have addressed ways to improve the success of selective biliary cannulation in endoscopic retrograde cholangiopancreatography (ERCP). The objective of this study was to assess the efficacy of deep bile duct access using a short-wire system with sphincterotome and guidewire controlled only by the endoscopist.
Methods This was a prospective study of 70 patients with biliary diseases subjected to ERCP. Biliary cannulation was performed by the endoscopist without direct cooperation of the assistant in two centers with different experience in ERCP. The RX Biliary System (TM) was used in all patients. Efficacy (success rate and time to cannulation) of deep bile duct access and procedure-related complications were determined.
Results Overall guidewire cannulation was successful in 65 of 70 patients (92.9%). Nonintentional pancreatic duct cannulation with the guidewire was performed in 22 patients (31.4%). Additional techniques were needed in 18 patients (25.7%): guidewire into the pancreatic duct in 11 patients (15.7%); contrast-medium was used in 13 patients (18.6%); and precut was performed in 3 patients (4.3%). Attempts at papilla cannulation numbered < 10 in 48 patients (68.6%), and time to biliary cannulation was < 10 min in 42 patients (60%). Minor complications occurred in five patients (7.1%). There were no significant differences between patients in both centers.
Conclusions The short-wire system allows the endoscopist to have access to the bile duct with a high success rate-early and safely-without the direct participation of the assistant.
