[Patient with stomach polyps--a risk group for colorectal tumors? Haemoccult studies on 106 patients].

106 patients in whom from 1 to 4 years ago a gastric polyp had been removed were examined for occult blood in the feces (haemoccult test). It should be tested whether in carries of gastric polypi increasingly appear colorectal tumors. Altogether 15 patients with colorectal tumours were found among the 106 carriers of gastric polypi. In 11 patients a removal of an adenoma from the colon was performed already before the haemoccult-examination. With the help of the haemoccult-examination 2 carcinomas of the colon and 2 carriers of adenomas were newly recognized as well as 2 recidivations of adenomas. Carriers of gastric polypi should be regarded as risk group for colorectal tumours. The dispensary care must be extended not only to the stomach but also include a careful anamnesis with regard to colorectal tumours and the search for occult blood in the feces.
