The Oregon Clinic Gastroenterology East our physicians are leaders in caring for patients with diseases of the esophagus, stomach, small intestine, colon, rectum, pancreas, gallbladder, and liver. We are committed to providing compassionate, expert care to every patient.

We continually seek advanced techniques for diagnosis and treatment. We were the first clinic in Portland to use endoscopic ultrasound, an imaging method that enables physicians to see and identify changes in the digestive tract more accurately. This technique benefits patients in many ways, from early detection to the prevention of unnecessary surgery.  We also offer spyglass technology giving our physicians the ability to directly look into bile ducts. Our capsule and balloon enteroscopy techniques allow for a thorough evaluation of the small intestine. 

Since November 2014, each of our three gastroenterology groups has been participating in the GI Quality Improvement Consortium (GIQuIC) program. Being part of this organization requires a focus on enhancing patient care through real-time peer-based performance evaluation. Click to read more on the GIQuIC website.
