Endoscopic fenestration treatment for pneumatosis cystoides intestinalis in patient with recurrent colonic intussusception.

Pneumatosis cystoides intestinalis (PCI) is a rare disease characterized by intestinal mural pneumatized cysts that appear most commonly in the colon [1] [2]. Although primarily asymptomatic, PCI occasionally causes intussusception that usually requires surgical treatment [3] [4]. Hyperbaric or high-concentration oxygen therapy is reportedly effective, though complete remission is uncertain [5]. We present the first report of an endoscopic fenestration procedure used for successful treatment of PCI with recurrent intussusception.
