Resection of polyps from the right side of the colon using hot forceps is associated with perforations and a relatively high rate of delayed bleeding. High grade dysplasia in a polyp is synonymous with carcinoma in-situ or intramucosal carcinoma. A 3mm adenoma is found in addition to large internal hemorrhoids. A colonoscopy must be performed given the presence of the adenoma. A 3 mm polyp found during flexible sigmoidoscopy should be biopsied.
Colonoscopy is indicated only if the polyp is an adenoma.
A 2.5cm sessile adenoma is removed in toto. No other lesions were found , pathology reveals a tubulovillous adenoma without severe dysplasia. If the stalk is invaded, surgical resection is always needed, regardless of resection margin involvement.
