GARCIA-CANO, Jesús et al. Pancreatic stent insertion after an unintentional guidewire cannulation of the pancreatic duct during ERCP. Rev. esp. enferm. dig. [online]. 2018, vol.110, n.7, pp.416-420. ISSN 1130-0108.


the guidewire (GW) may enter the pancreatic duct during common bile duct (CBD) cannulation attempts in endoscopic retrograde cholangiopancreatography (ERCP). After GW passage into the pancreas, the most effective maneuver for CBD cannulation and pancreatitis prevention has not been determined.


to study CBD cannulation and post-ERCP pancreatitis rates when a pancreatic stent is inserted after an unintentional GW cannulation of the pancreatic duct.

Material and methods:

a retrospective analysis of patients undergoing ERCP for biliary drainage that were included prospectively into a database. After unintentional GW cannulation of the pancreatic duct, a straight 5-Fr and 4-cm long plastic stent was inserted. The stents had no internal flaps to facilitate expulsion. CBD cannulation attempts were made above the stent. A pancreatic sphincterotomy was performed in patients older than 60 years before stent insertion.


a total of 46 pancreatic stents were inserted during 154 ERCP (29.8%) procedures. In the stent group, CBD cannulation was accomplished in 44/46 (95.6%) subjects. A total of 21/46 (45.6%) pancreatic sphincterotomies were performed. Only 1/46 (2.17%) mild pancreatitis cases were observed and most stents were spontaneously expelled.


in this study, the CBD was eventually reached with the insertion of a plastic pancreatic stent after an unintentional GW passage into the pancreatic duct while attempting a CBD cannulation. No adverse events were observed following pancreatic stent insertion.
