Colonoscopy is recommended for all adults at age 50 (with average risk) for routine colon cancer screening, whereby a careful examination is performed to discover and remove polyps. This procedure, which is performed under conscious sedation, has many indications including unexplained diarrhea, rectal bleeding, a family history of colon cancer and constipation. This is routinely performed at one of our outpatient endoscopy centers or at the hospital.

Endoscopic Ultrasonography (EUS)

This procedure allows your physician to examine your esophageal and stomach linings, and the walls of your upper and lower gastrointestinal tract. With the help of an endoscope and an ultrasound probe, your physician will use sound waves to create visual images of your digestive tract. EUS can be used to diagnose conditions that may cause abdominal pain or abnormal weight loss, as well as examine known lumps or lesions.

Endoscopic Retrograde Cholangiopanctreatography (ERCP)

This procedure is performed by your physician at the hospital to examine your bile ducts (drainage tubes from the liver/gallbladder) and the pancreas. Tissue can be sampled during this examination if needed, and therapeutics may be required depending on your illness, such as the placement of a stent. This procedure is performed in the hospital.

This test is performed at the hospital to measure exactly how the esophagus swallows. This allows the physician to diagnose and treat any underlying esophageal disorders.
