RESUMO
Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by multiple gas-filled cysts of varying size in the wall of gastrointestinal tract. PCI may idiopathic or secondary to various disorders. The etiology and pathogenesis of PCI are unclear. Treatment is usually conservative, and includes oxygen and antibiotics therapy. Surgery is reserved for cases of suspected inconvertible intestinal obstruction or perforation. Eleven patients who were diagnosed with PI between 2005 and 2015 were reviewed. We report three cases of PCI and describe causes and complications. The most important point in the treatment of PCI is to determine whether the patient needs surgery. Conservative care should be considered first if the patient is stable. If any complication is observed, such as ischemia in the intestine, surgery is needed. It is important to choose the best treatment based on prognostic factors and CT findings.
