[Diagnosis and treatment of benign nonepithelial tumors of the large intestine].

The diagnosis and treatment of benign non-epithelial tumors of the large intestine are discussed. The cases are rare and present certain diagnostic difficulties. It is possible to establish the diagnosis of the tumors by x-ray examination with double contrasting of the large intestine and by transrectal needle biopsy of the neoplasms. The diagnosis may be improved by applying fiberoptic colonoscopy. Resection of the colon and hemicolectomy seem to be the operation of choice.
