Rare Complication of Sigmoid Colon Perforation by Migrated Plastic Biliary Stent: Two Case Reports and Literature Review

Abstract

Objective and Introduction:The endoscopic insertion of biliary stents is an alternative solution for biliary tree obstruction in benign or malignant diseases. Despite the availability of a safe and convenient method that has been used for many years, complications still exist. We reported two cases of rare complication of biliary migration resulting in colon perforation. Conclusion:Biliary stent migration is usually asymptomatic. Early intervention should be considered in case of suspicion of peritonitis or severe abdominal pain.
