Diagnostic testing we offer

Our hospital is equipped with advanced equipment and technology to better support the care we provide. To properly diagnose and treat patients with gastrointestinal disorders, our experts may use any of the following imaging and endoscopic procedures:


A procedure used to examine your colon and rectum to detect early signs of colorectal cancer. Colonoscopy is the most common method used to screen for cancer; however, depending on your personal history and risk factors, we can provide alternative screening options, including stool DNA and occult blood tests, flexible sigmoidoscopy and virtual colonoscopy. The American Cancer Society now recommends regular colon cancer screenings for adults 45 years and older.

Endoscopic ultrasound

A minimally invasive procedure that combines endoscopy and ultrasound to obtain images and information about the digestive tract and the surrounding tissues and organs.

Endoscopic retrograde cholangiopancreatography (ERCP)

Combines X-ray and the use of a special scope with an ultrasound tip to evaluate conditions in the gallbladder, liver, bile ducts and pancreas.
