    Lactose intolerance

    The digestive system organs in the abdominal cavity include the liver, gallbladder, stomach, small intestine and large intestine.

    Lactose is a type of sugar found in milk and other dairy products. Lactose intolerance develops when the small intestine does not make enough of an enzyme called lactase. The body needs this enzyme to digest lactose.

    Lower esophageal ring

    A solution containing a dye (barium), which is visible on X-rays, has been swallowed (upper GI series) and X-rays have been taken of the esophagus. There is a narrowing near the stomach (indicated by the arrow). This non-cancerous ring of tissue (Shatzki's ring) may cause swallowing problems (dysphagia) and can be treated with dilation of the stricture.

    A lower esophageal ring is an abnormal ring of tissue that forms where the esophagus (the tube from the mouth to the stomach) and stomach meet.
