Prophylactic pancreatic duct stenting for biliary-type stenosis of Oddi sphincter with difficult cannu- lation

Abstract

Objective To evaluate the clinical value and efficacy of prophylactic pancreatic duct stenting for biliary-type stenosis of Oddi sphincter with difficulty cannulation. Methods The present study was a retrospective study of 63 patients with biliary-type stenosis of Oddi sphincter and difficult cannulation. The stent group consisted 30 patients who underwent prophylactic pancreatic duct stenting from February 2010 to February 2011 and the control group included 33 patients who underwent only ERCP without prophy- lactic pancreatic duct stenting from January 2009 to January 2010. The incidence of postoperative pancreatitis were compared between the two groups. Results The incidence of postoperative pancreatitis of the control group was significantly higher than that of the stent group （ P 〈 0. 05 ）. Conclusion For patients with defi- nite diagnosis of biliary-type stenosis of Oddi sphincter and difficult cannulation, prophylactic pancreatic duet stent placement is safe and effective.
