The health government and also the professionals except the new screening test programme to put a stop the increasing number of colon and rectum cancer diseases, which have caused high mortality in Hungary. Believe in the success of this programme the authors give a short overview about the precancer status and alterations of the large bowel, focusing on colorectal adenoma. In particular, the pathological anatomy, symptomatology, diagnostics, therapy, treatment and prevention possibilities of adenomas are described in details. There were 3419 total colonoscopies carried out in the Laboratory of Endoscopy in Albert Schweitzer General Hospital of Hatvan between 31st January 1991 and 31st December 2001. All patients had bowel motility problems, abdominal pains, bloody stools or change of bowel movement habit. 941 large bowel polyps were diagnosed at 628 patient. 821 of them were removed with endoscopic polypectomy, 11 with mucosectomy, 43 with piecemeal polypectomy and 20 with surgical interventions. 38 carcinoma in situ and 94 serious dysplasia alteration were removed. After the endoscopical therapeutical interventions 5 complications were detected and one patient died. There were no complications after the surgical interventions. They analyse their patients in base of the polyps place, shape, number and histological structure of alterations, level of dysplasia and the type of interventions. It is confirmed that the total colonoscopy is the most adaptable method for examining the large bowel, and endoscopic polypectomy is the most efficient colorectal cancer preventing method, which could only be realized with the successful interdisciplinary cooperation of the gastroenterologist, the surgeon, the pathologist and radiologist.
