Risks

EUS is generally safe when performed at a center with an experienced and expert health care team. Your doctor will discuss with you the risk of complications from EUS. These risks are most commonly associated with fine-needle aspiration.

Risks may include:

  • Bleeding
  • Infection
  • Tearing (perforation) of the intestinal wall or throat
  • Pancreatitis, if fine-needle aspiration of the pancreas is done

You can reduce your risk of complications by carefully following your doctor's instructions for preparing for EUS.

Call your doctor immediately or go to an emergency room if you experience any of the following signs or symptoms:

  • Fever
  • Chest pain
  • Shortness of breath
  • Black or very dark-colored stool
  • Severe or persistent abdominal pain
