Primary choledocholithiasis after long-term self-expansible metallic stent for ampullary carcinoma: A rare case

Abstract

AbstractIn patients with periampullary carcinoma presenting in the inoperable stage, self-expansible metallic stents (SEMS) are preferred for palliation of jaundice. The primary common bile duct (CBD) stones are very rare in a patient who is treated with SEMS for ampullary cancer. We report here a case of primary CBD stones after 2 years of placement of SEMS, whether, reflux of duodenal contents or foreign body reaction to the stent material is the etiology of the formation of stone is a matter of debate.
