Huge Mass Of The Descending Colon (10 of 25)

Polyps greater than a third of the luminal circumference, those crossing two haustral folds and those involving the base of the appendix or ileo-caecal valve are often best referred for segmental resection or to a specialist endoscopist. Polyps found in close proximity to colorectal cancers should be documented rather than removed since polypectomy adds an unnecessary risk if the polyp lies within the resection margins of the tumour. Moreover, some have raised concerns that tumour seeding may occur into recent polypectomy sites and suggest that synchronous polyps be removed after appropriate surgical resection of the tumour.
