Application of Soehendra stent retriever in patients with pancreatic or bile duct stricture / 解放军医学杂志

ABSTRACT

Objective To evaluate the efficacy of Soehendra stent retriever as used as a dilator for the patients with high grade stricture of pancreatic or bile duct. Methods Forty-eight patients, who underwent endoscopic retrograde cholangiopancreatography (ERCP) from Jan. 2010 to Oct. 2012 in Endoscopy Department of General Hospital of Shenyang command, were found to have pancreatic or bile duct stricture. Dilation was then attempted using a dilating sound. Once the stricture could not be traversed, the Stent Retriever was inserted over the sound to dilate the stricture. Results A total of 554 patients were diagnosed to suffer from pancreatic or bile duct stricture with the aid of ERCP. Among them dilatation of stricture with catheter failed in 48 cases (8.7%) and Soehendra stent retriever was then used for dilatation. Of the 48 cases, ERCP revealed common bile duct stricture in 8 patients, common hepatic duct stricture in 6 patients, porta hepatis stricture in 5 patients, stricture at neck of pancreas stricture in 18, stricture at body of pancreas in 4, stoma stricture after liver transplant in 4, and occlusion of metallic stent in 3 patients. For these cases, Soehendra stent retriever was used to dilate the stricture prior to setting stent or endoscopic nasobiliary drainage (ENBD) with a success rate of 100%. No related complication was found. Conclusion Pancreatic and bile duct stricture can be dilated successfully with the Soehendra stent retriever. The procedure is of low risk and highly effective.
