Information for Patients


A fistula is an abnormal connection between two parts inside of the body. Fistulas may develop between different organs, such as between the esophagus and the windpipe or the bowel and the vagina. They can also develop between two blood vessels, such as between an artery and a vein or between two arteries.

Some people are born with a fistula. Other common causes of fistulas include

  • Complications from surgery
  • Injury
  • Infection
  • Diseases, such as Crohn's disease or ulcerative colitis

Treatment depends on the cause of the fistula, where it is, and how bad it is. Some fistulas will close on their own. In some cases, you may need antibiotics and/or surgery.

Salivary Gland Disorders

Your salivary glands make saliva - sometimes called spit - and empty it into your mouth through openings called ducts. Saliva makes your food moist, which helps you chew and swallow. It helps you digest your food. It also cleans your mouth and contains antibodies that can kill germs.

Problems with salivary glands can cause the glands to become irritated and swollen. This causes symptoms such as

  • Bad taste in the mouth
  • Difficulty opening your mouth
  • Dry mouth
  • Pain in the face or mouth
  • Swelling of the face or neck

Causes of salivary gland problems include infections, obstruction or cancer. Problems can also be due to other disorders, such as mumps or Sjogren's syndrome.

  • Drooling
  • Salivary duct stones
  • Salivary gland infections
  • Salivary gland tumors
  • Sialogram
