Colon and Rectal Surgery

Anorectal Surgery

The surgeons in the Division of Colon and Rectal Surgery at Tufts Medical Center treat a wide array of anorectal diseases, including hemorrhoids, abscesses and fistulas and fissures.


Hemorrhoids are swollen veins in the lower rectum or anus that can be very painful. Our colon and rectal surgeons treat a large number of hemorrhoids each year. Our surgeons often use Rubber Band Ligation or Infrared Coagulation. These procedures are performed in the office during a regular patient visit—meaning that the patient does not need to prepare as they would have to for a serious surgery.

Rubber Band Ligation is one of the most commonly used treatments for internal hemorrhoids. It is a relatively low-risk procedure and is often the preferred method used by our surgeons. Learn more about Rubber Band Ligation.

Infrared Coagulation treatments are the second most common treatment option for internal hemorrhoids. This treatment is fast, easy, usually painless and rarely results in complications. Learn more about Infrared Coagulation.

Abscess and Fistula

An abscess is a pus filled cavity near the anus or rectum. A fistula starts with an abscess that forms a small tunnel under the skin. Our surgeons have strong experience in surgically treating both abscesses and fistulas.

For an abscess, our physicians will drain the lump either in the office with local anesthetic or in the operating room using a regional or general anesthetic.

Fistulas are most often treated via surgical procedures. Our Tufts Medical Center Colon and Rectal surgeons will determine the procedure needed depending on how much of the anal sphincter muscles lie between the fistula tract and the skin.

Learn more about the treatment options for abscesses and fistulas.


An anal fissure is a tear in the skin that lines the anus. Anal fissures are common and usually heal on their own. For fissures that do not heal on their own or become chronic, surgery may be needed.
