[Results of colonoscopic examination 2 years after polypectomy of an intestinal adenoma].

The authors examined 204 patients after a two-year interval following endoscopic and surgical polypectomy resp. of an adenoma of the large intestine. The group comprised 67 patients (32.8%) with a metachronous adenomatous polyp. In none of these patients carcinoma was diagnosed. In patients where originally a solitary adenoma was diagnosed a metachronous adenoma developed in 14%. In the group with originally synchronous polyps a metachronous polyp developed in 85.2%. The male:female ratio during the original examination and after two years in relation to an adenoma of the large intestine did not change significantly. The test for occult blood in the faeces made by the Haemoccult test gave in 3% falsely positive results and in 27% falsely negative results. According to the results of the examination the two-year interval is sufficient for repeated coloscopy within the framework of dispensarization of patients after polypectomy. In exceptional cases the interval of the check-up must be adjusted to the patient's condition with regard to the follow up by and collaboration with the general practitioner.
