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.
