Endoscopy Procedures

A Colonoscopy enables the physician to look inside a patient's entire large intestine. This procedure is used to look for early signs of cancer in the colon and rectum, as well, as diagnose the causes of unexplained bowel habits.

Before the procedure, the patient is usually given a mild sedative. While the patient lies on their left side, the physician will insert a long, flexible, lighted tube into the patient's rectum and slowly guide it into the colon. The tube, called a colonoscope, transmits an image of inside the colon and can inflate the colon with air to help the physician see clearly.

The physician can remove all or part of an abnormality using tiny instruments passed through the scope. If there is bleeding, the physician can pass an instrument through the scope to stop the bleeding or inject medicine.

Esophagogastroduodenoscopy (EGD) or Upper Endoscopy is an examination of the esophagus, stomach, and duodenum. During this procedure, a thin flexible tube, containing a light source and camera, is placed down the patient's throat. The physician is able to examine the patient's upper GI tract from the video output of the camera. Before the EGD procedure an anesthetic spray is used to numb the back of the throat, and sedation is given for the 15-minute exam.
