Mayo Clinic's approach

  • Teamwork. Doctors at Mayo Clinic — including specialists who treat diseases of the digestive system (gastroenterologists), lung disease (pulmonologist) and cancer (oncologist) — work together to help develop the most appropriate treatment plan for you.
  • Expertise. The skills of the doctors performing the procedure and analyzing the results are critical to the success of EUS imaging and guided biopsy. Mayo has specialists with advanced training in EUS and pathologists who specialize in diagnosing cancers. Each year, Mayo Clinic specialists perform more than 3,100 endoscopic ultrasounds to assess digestive and lung diseases.
  • New ideas. Mayo researchers are working to improve EUS and explore further applications of the technique. You have access to the expertise of Mayo's clinician-researchers.
