Abstract
A review of 464 consecutive polypoid lesions of the colon reveals that virtually all pedunculated polyps and over 80% of 218 sessile polyps were removed colonoscopically. Although size or location of the lesions occasionally precludes colonoscopic excision, the endoscopic appearance of a sessile polyp is the most important factor in deciding upon the method of excision. In gneeral, smooth, soft, nonulcerated sessile lesions of all sizes were excised endoscopically, while approximately half of the larger (2-6 cm) firm, irregular-surfaced, benign sessile lesions, and all ulcerated or malignant sessile lesions required laparotomy for proper management. All polypoid lesions should be viewed endoscopically before deciding the method of excision, regardless of their size, location, or general appearnce by barium enema. Experience with endoscopic morphology and snare electrocautery technics was most important, since more than 85% of all polypoid lesions in this consecutive series were removed endoscopically.
