More About Colo-Rectal Surgeon

A Colorectal Surgeon is a physician who specializes in the diagnosis and treatment of anorectal and colorectal conditions (conditions of the colon, rectum and anus).

Investigations like fecal occult blood test (FOBT), flexible sigmoidoscopy, colonoscopy etc are rquired.

If you are having Anal or groin area abscess, boil, Bowel or urinary incontinence, Rectal bleeding or black stools with a sticky, tarry texture you should consult a colorectal surgeon.

Most people will experience some pain but that can be managed with pain killers and it will improve with time.

Yes, people can live without a colon, but may need to wear a bag outside their body to collect stool. However, a surgical procedure can be performed to create a pouch in the small intestine that takes the place of the colon and in that case wearing a bag is not necessary.
