CASTANO, Rodrigo et al. Biliary cannulation with a guidewire in pancreatic duct. Rev Col Gastroenterol [online]. 2009, vol.24, n.2, pp.144-147. ISSN 0120-9957.

Background and objectives. The angular stone in endoscopic colangiography is an atraumatic and fast biliary cannulation, which results in the success of the procedure. In this series of 10 patients an easy technique is described that helps to cannulate a difficult biliary conduit. Methods. In cases of repeatedly cannulation of pancreatic duct and not selectively the biliary tract; it is suggested to leave the guide wire in the middle of the Wirsung duct and to retire the cannula or sphincterotome. The cannula or sphincterotome is reintroduced by the work channel next to the guide wire in the pancreatic conduit. With the guide in the pancreatic duct the cannula advances with better direction, stability and firmness of papilla. Results. This technique cases was used in 10 patients (6 hospitalized and 4 ambulatory) and was successful in all the patients, avoiding the necessity of the access to the biliary route by the technique of the precut. No complication was documented. Conclusions. Use of this technique can help to reduce the number of sphincterotomies by precuts, with increased risks of pancreatitis, bleeding and perforation. The proposed technique can help us in any difficult cannulation of the biliary route.
