EUS is generally safe when performed at a center with experience and expertise in the procedure. Your doctor will discuss with you the risk of complications from EUS, which may include:

  • Bleeding, especially if fine-needle aspiration is done
  • 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.

Signs and symptoms to watch for after your EUS include:

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

Call your doctor immediately or go to an emergency room if you experience any of these signs or symptoms.
