Colorectal surgeons operate principally on the diseases of the colon and rectum. They provide diagnostics for diseases such as colorectal cancer, colitis and polyps using colonoscopy, flexible sigmoidoscopy and colonic imaging with CT. They also treat many common conditions such as haemorrhoids, anal fissures and diverticular disease and manage functional disorders such as constipation and incontinence. Major surgery for bowel cancer, colitis and diverticular disease includes bowel resection, pouch formation and stomas.
The UK organisation that supports colorectal surgeons is the Association of Coloproctology of Great Britain and Ireland (ACPGBI)
