Case report: Migratory biliary stent resulting in sigmoid colon perforation.

Biliary stent insertion during endoscopic retrograde cholangiopancreatography is a therapeutic intervention to relieve obstruction and facilitate flow through the biliary tree. In rare circumstances, these stents can migrate and result in distal gastrointestinal perforation, which may necessitate endoscopic or surgical intervention. We report a case involving a 79-year-old female who presented with peritonitis due to sigmoid colon perforation following biliary stent migration.
