[Management of rectal and ureteral obstruction following gastrointestinal cancer].

During the period from June 1973 to August 1982, thirteen patients with gastric cancer and seven patients with colorectal cancer received surgical treatment due to the obstruction of the rectum or ureter. Of thirteen gastric cancer patients, 11 underwent the formation of the artificial anus for rectal obstruction. Nephrostomy was performed in 4 gastric cancer patients with ureteral obstruction. Seven patients with colorectal cancer underwent the formation of the artificial anus for rectal obstruction. In the recurrent cancer of the gastrointestinal tract, obstruction of the rectum or ureter mainly occurred due to peritoneal invasion or tumor formation. During laparotomy, OK-432, a Streptococcal preparation, was administered with a large dose of 100 K. E. to the patients with advanced or recurrent cancer foci. The prognosis for those patients was poor, and the main reason for poor survival was the advancement of disease in the cases of rectal or ureteral obstruction.
