[Endoscopic results of treating malignant polyps of the large intestine].
We present own material of 291 colonoscopic polypectomies performed between 1991 and 1996. In this group 15 (5.1%) polyps contained malignancy (14 adenocarcinoma, 1 lymphoma). Analysis of this material supported well known fact of higher malignant potential of large polyps and of adenoma villosum. In all but one cases of cancers located in polyps histological examination confirmed free margin of electro-resection. There were no local recurrences during follow-up lasting 2 month to 5.5 years. Patient with lymphoma malignum (large polyp over 4 cm in diameter) underwent typical chemotherapy and is now, one year after polypectomy disease-free. In this group colonoscopy is repeated every 3 months during first two years and every 6 months later. In cases of cancer-free margin of electro-ablation colonoscopic polypectomy seems adequate treatment of malignant large bowel polyps.
