Duodenal perforation by a Wallstent.
Endoscopic and/or radiological insertion of metallic mesh stents has recently been described as an alternative to palliative bypass operation in patients with gastric outlet obstruction caused by advanced malignant disease. We report a complication caused by migration and late perforation of the duodenum by a Wallstent, which raised concerns about the place of this procedure as an alternative to surgical bypass. The Wallstents have sharp ends and could cause ulcers or perforation of the viscus. Modification of the current Wallstent design may be needed.
