[Personal experience in colonoscopy and polypectomy].

The purpose of this presentation is to point out the importance of this new diagnosis and treatment method, recently incorporated. The studies were done with the Fibroscope F9-A with doble channel, equipped with an desection smear for polipectomies and an extracting forceps. The patients arrive with their intestine perfectly cleaned with classical methods. This detail is most important for the polipectomies. If the local conditions aren't the desired, presence of bowels or barium of an previous enema, we postpone both, examination and polipectomy, because those are causes of false diagnosis in the first case or eventual accidents in the second condition. Regarding this, we had an performing doing a biopsy in an stenosing neoplasm of the sigmoid colon. We believe it convenient to prevent this complication, to reduce the air pressure before performing the biopsy. Of the 160 patients examinated, 54 had no patology, 32 had polips and of this group 4 had multiple poliposis, 4 had association with diverticulosis and 3 associated with neoplasm. (4 were neoplasm, 10 stenosis without mucous lesions, 1 villous adenoma, 1 megacolon and 1 rectitis). We made 12 polipectomies, 10 with the conventional technique and 2 associated with surgery. We had no accidents and one of them was an early stage of colon cancer.
