title: [Colonoscopy as primary procedure in the diagnosis of colonic neoplasms].
abstract: Experience with colonoscopy as an initial procedure in the study of the colon is presented. 3.450 colonoscopies in patients with GI symptoms were performed by trained endoscopists using the intermediate length scopes (130cm) without fluoroscopy. In 90% of the cases the whole colon was studied in a mean time of 20 minutes. 382 neoplasms (11.07%) were diagnosed. Polips represented 90% of the lesions and 34.3% of them were adenomas. 30% of the adenomas and 34.4% of the malignant tumors were localized in the right colon. We emphasise that 82.7% of the polips found in the right colon were adenomas. As a side effect we had a sigmoid perforation, it represents 0.03%. Colonoscopies performed by a trained endoscopist is a highly diagnostic method with low degree of complications, making it the procedure of choice in the study of the colon in specialized centers.
