Gastroenterology West at SW Barnes Road
About
At The Oregon Clinic Gastroenterology West, our experienced, board-certified physicians are committed to quality care in all aspects of gastroenterology and hepatology.
Our doctors are trained in advanced therapeutic and diagnostic procedures and are able to treat a wide variety of conditions.
Advanced technology, including Spyglass Endoscopy and Balloon Enteroscopy, allow for early detection of disease and prevention of unnecessary surgeries.
Thanks to our state-of-the-art outpatient endoscopy center and our close proximity to Providence St. Vincent’s Medical Center, we are able to offer our patients cutting edge diagnostic and therapeutic procedures in a comfortable and reassuring environment. We use safe and up-to-date sedation techniques.
We specialize in colon cancer screening that uses the gentlest bowel preparation and the most effective sedation medications.
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.
