Blind loop syndrome

Definition:

Occurs when a part of the intestine is blocked off from the rest of the intestines so that nothing can pass through.

Causes, incidence, and risk factors:

Blind loop syndrome is a complication that occurs after a subtotal gastrectomy (surgical removal of part of the stomach) or as a complication of inflammatory bowel disease or scleroderma. Distention, decreased flow, or stasis of intestinal contents causes the symptoms. Increased bacterial growth occurs as a result of decreased flow. Bile salts needed to digest fats are ineffective, resulting in fatty stools and poor absorption of fat and fat soluble vitamins. Vitamin B12 deficiency may occur due to bacterial uptake of the vitamin. The conditions that cause the disease are also the risk factors.
