Pneumatosis cystoides intestinalis. Report of two cases.

The histories of two patients with pneumatosis cystoides intestinalis are reported. In the first case a left hemicolectomy was performed because of suspicion of polyposis coli. The other patients was given symptomatic treatment. Conservative treatment is recommended by most authors, but since the disorder is seldom seen, unnecessary surgery is often performed because of incorrect preoperative diagnosis.
