Endoscopy Center

Endoscopy uses an advanced medical instrument called an endoscope. It is inserted directly into a hollow organ or body cavity, like the stomach, to see inside. Endoscopy is often used to:

  • Investigate symptoms, mostly in the digestive system    
  • Perform a biopsy
  • Remove polyps or foreign objects    
  • Repair bleeding vessels

The Trios Endoscopy Center has locations at the Trios Care Center at Vista Field and at the hospital. Both have the latest technology and caring medical staff with experience in a variety of outpatient procedures.
