Haemorrhage Due to Erosion of a Metal Biliary Stent through the Duodenal Wall

Abstract

Self-expanding, metal biliary stents have recently been used in malignant obstructive jaundice as their large diameter reduces the likelihood of occlusion by biliary sludge and bacterial biofilm. However, there is a significant rate of late obstruction by tumour overgrowth and infiltration through the wire mesh. Our case of stent erosion through the duodenal wall, resulting in massive haemorrhage, is a hitherto unreported serious complication of the Wallstent (Schneider). Its occurrence may be suggested by continuous upper abdominal pain, gastrointestinal bleeding or late expansion of the stent.
