Migration of endoscopic biliary stent and small bowel perforation within an incisional hernia

Abstract

Long-term complications from biliary stents, such as migration and perforation, are unusual but may occur. Distal perforations most commonly involve the colon or distal ileum. This report describes the case of a perforated small bowel, secondary to a stent trapped within an incisional hernia. Patients with comorbid abdominal pathologies, including colonic diverticulae or abdominal herniae, may be at increased risk of perforation from migrated stents.
