[Rectocolonic polyps in Senegal. Results of 1500 lower endoscopies carried out at the Dakar General Hospital].

57 polyps were discovered during 1,500 low endoscopies, and 24 of them were adenoma. In the same period of time, 26 proctocolitic adenocarcinomas were found. Adenomatous polyps appear to be 5 times less frequent in Senegal than in industrialized countries and frequency of colitic cancer should be of the same frequency, that is far less negligible. Even if proctocolitic cancer does not set up any Public Health problems one could envisage systematic screening of polyadenoma in every patient aged more than 40. Proctosigmoid being the seat of most adenoma, fibrosigmoidoscopy appears well adapted to this kind of screening because it does not require any preparation, it is easy to perform and well accepted.
