Endoscopy and Colonoscopy

Providence Digestive Health Institute offers a full range of general endoscopic procedures to help diagnose conditions affecting the digestive tract. Procedures include:  

Upper endoscopy

Sometimes called an EGD, this is a procedure used to look at the inner lining of the upper digestive tract (the esophagus, stomach and the duodenum or the first part of the small intestine).


This procedure uses a thin, flexible camera to examine the colon or lower intestine and is used to check for abnormalities or disease. 

Advanced endoscopy

This is a highly advanced procedure for complex diagnoses and treatments. Our experts diagnose and treat complex digestive disorders at three Advanced Endoscopy Centers in Oregon: in northeast and southwest Portland, and Newberg. These are highly specialized procedures not widely available at other systems in the region. With consistently higher success rates and lower complication rates than the national average, our program is the largest and most experienced diagnostic and therapeutic endoscopy program in Oregon.

  • Endoscopic retrograde cholangiopancreatography (ERCP) with 3D digital imaging
