Short Bowel Syndrome (SBS) Intestinal Surgeries"

Surgery to remove a large part of the intestines unites many SBS patients

Those with Short Bowel Syndrome may have had an intestinal surgery to remove part of the bowel, also known as a resection.

Intestinal Surgeries or Bowel Resections And the intestinal Tract

To understand the different types of intestinal surgeries that remove part or all of the bowel — often called resections — you must first understand the anatomy of the intestinal tract.

The image below is for illustrative purposes and is not an exact model of the human body.

Possible Causes for a resection

  • Inflammatory bowel disease (Crohn’s disease or Ulcerative colitis)
  • Bariatric or gastric bypass surgery complications
  • Trauma of the intestines
  • Vascular events
  • Cancer
  • Knotting or twisting of the intestines
  • Birth defects

Types of bowel surgery

Jejunocolic anastomosis: In this type of surgery, the jejunum is connected to the large intestine, also called the colon. The ileum and sometimes the muscle that joins the large intestine to the small intestine—the ileocecal valve—are removed. Parts of your colon may also be removed in this procedure, and the two sections (jejunum to colon) are then joined.

End-jejunostomy: This surgery involves removal of the colon, ileum and some of the jejunum. The remaining jejunum is then connected to a surgical opening (called an ostomy) created through the skin in the belly (abdomen). In this type of surgery, a part of the small intestine will be attached to the skin of the belly. The opening this creates is called a stoma. Stools or waste material go through the stoma into a drainage bag that is located outside of the body.

Jejunoileal anastomosis: In this surgery, parts of the jejunum and ileum are removed, and the remaining parts are connected to the colon. (Anastomosis means "reconnection.") This procedure leaves the full length of the colon intact. Many people with this type of surgery do not require nutritional support.

The Use of Ostomies

An ostomy is a surgical opening that is created specifically for the discharge of the body’s wastes. It connects the end of the small or large bowel to a surgically made opening in the abdomen, called a “stoma,” and directs waste out of the body into a pouch. Ostomies may be temporary or permanent, depending on the reason for surgery. It is not uncommon for SBS patients to have an ostomy.
