Gastric pneumatosis: sign of biliary stent-related perforation.
Gastric pneumatosis developed 4 months after a Carey-Coons biliary endoprosthesis was placed in an 85-year-old woman with pancreatic carcinoma. Radiographs revealed a change in the position of the stent. This combination of findings suggested that more than simple stent migration had occurred. At endoscopy, duodenal perforation was confirmed and the stent repositioned. Subsequently, the pneumatosis resolved.
