Juxtapapillary duodenal diverticular bezor as an exceptional cause of biliary stent obstruction. Case report.

INTRODUCTION: we describe the first case in literature of biliary stent obstruction by bezoar impaction in a iuxtapapillary duodenal diverticulum. CASE REPORT: this case illustrates an juxtapapillary duodenal diverticulum and bezoar in it causing obstructive jaundice in subject with two biliary stents for cholangiocarcinoma (Klatskin's tumor) in the absence of bile duct stones. RESULT: successful treatment with endoscopic stent removal and diverticulum toilette. Obstructive jaundice was cured after endoscopic removal of the bezoar and stent substitution. DISCUSSION: the presence of a bezoar and its possible contribution to the pathogenesis of pancreatitis in the presence of periampullary extraluminal duodenal diverticula makes endoscopic intervention for removal of the bezoar necessary and effective. CONCLUSIONS: biliary bezoar is a very rare but treatable cause of stents obstruction in patients with juxtapapillary duodenal diverticula. Endoscopic retrograde cholangiopancreatografhy is helpful in making diagnosis and for resolutive treatment.
