title: [Therapeutic colonoscopy in patients with colonic and rectal polyps].
abstract: 598 colorectal polyps were removed by therapeutic colonoscopy from 377 patients, of both sexes, between 1 and 88 years old, most of them with lower digestive symptoms. The polyps were unique in 67.37% and multiple in 32.63% of patients, and mostly located in rectum and sigmoid colon; 42.14% were pedunculated, 33.95% sessile++/sub-pedunculated, and 23.91% sessile in shape. In 51% the size was over 10 mm in diameter. Histologically, 68.68% were of epithelial neoplastic type: 60.91% adenoma; 6.42% adenoma with adenocarcinoma, and 1.35% polypoid carcinoma. 30.64 were epithelial non-neoplastic type: 20.32% hyperplastic polyp, and 0.51% hyperplastic polyp with tubular adenoma. Two patients (0.53%) had lower digestive hemorrhage immediately after the polypectomy. The complications were controlled with conservative measures without blood transfusion.
