Gastric outlet obstruction accompanied by a diffuse segmental pneumatosis cystoides intestinalis

Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by multiple thin-walled, gas-filled cysts in the submucosal or subserosal layer of the gastrointestinal wall. PCI is not well understood. Symptoms associated with it are nonspecific, commonly including abdominal pain and distension, diarrhea, bloody stool, and constipation. In this report, we present an interesting case of gastric outlet obstruction associated with PCI in an elderly male patient, who was successfully treated by the gastroenterostomy.
