RESUMO
Placement of an endoprosthesis for billiary obstruction has been advocated as an effective alternative for internal-external drainage catheters or surgical procedure. Endoscopic retrograde biliary drainage (ERBD) is a method of transpapillary insertion and placement of drainage tube in the billiary tree under the direct view of endoscope. Early complications following ERBD that develop within 4 weeks include obstruction of the stent, cholangitis, hemorrhage, acute pancreatitis, and bile duct or duodenal perforation. Late complications include obstruction of the stent and cholangitis, migration of the stent, and intestinal perforation. We expierenced a case of sigmoid colonic perforation following ERBD in a patient with multiple biliary tract stone and cholangitis. Thus we report this case with a brief review of the literature.
