Colonoscopy

Colonoscopy is a procedure that enables your doctor to examine the lining of the colon, also known as the large intestine. Colonoscopy is typically done to screen for colon polyps and colon cancer or to search for an explanation of symptoms (e.g. rectal bleeding or diarrhea). An instrument known as a colonoscope, a flexible tube about the thickness of your little finger, is used by the colonoscopy doctor during the colon examination.

There is a light source and camera on the end of the colonoscope; the image is projected onto a video screen. Polyps can be removed with the colonoscope (colon polypectomy) and biopsies (tissue samples) can also be obtained.

EGD (Upper Endoscopy

An upper endoscopy is a procedure that enables your physician to examine the lining of the upper GI tract that includes the throat, esophagus, stomach, and beginning of the small intestine (duodenum). Endoscopy is typically done to diagnose and treat conditions of the upper GI tract such as nausea, abdominal pain or GI bleeding.

The instrument is known as an endoscope and it is a flexible tube about the thickness of a pencil. There is a light source and camera on the end of the endoscope; the image is projected onto a video screen. While the patient is sedated, the endoscope is inserted into the mouth and advanced to the duodenum. Biopsies (tissue samples) can be obtained and treatment of active bleeding can be done. The procedure takes about 10-15 minutes. Intravenous medication is administered during the endoscopy to ensure a painless experience.
ERCP

An endoscopic retrograde cholangiopancreatogram (ERCP) is a procedure that combines the use of an endoscope with X-ray pictures to examine the biliary and pancreatic ducts. While the patient is sedated, the ERCP endoscope is inserted through the mouth and advanced until it reaches the point where the bile ducts and pancreatic ducts drain into the duodenum.

ERCP can diagnose and treat certain problems found during the test. If an abnormal growth is seen, a biopsy can be obtained. If a gallstone is present in a bile duct, the doctor can sometimes remove the stone with instruments inserted through the endoscope. A narrowed bile duct can be opened by inserting a small wire-mesh or plastic tube (called a stent) through the narrowed duct.

Office Consultations

When you schedule your consultation, you will be asked to fill out a patient questionnaire. The physician will review this questionnaire as well as any laboratory and imaging tests that are relevant to your visit. During the consultation, your physician will ask you about your symptoms and clarify any questions that might arise about your medical history or other information on the questionnaire. Your physician will then perform a physical examination if appropriate and will then conclude by discussing with you his thoughts, impressions, and recommendations.
