Understanding Upper GI Endoscopy (EGD):
EGD is a procedure in which a flexible tube is inserted through the mouth into the esophagus, stomach, and duodenum. It is used in the evaluation of various problems including difficult or painful swallowing, abdominal pain, and bleeding. Instruments can be passed through a channel in the endoscope to obtain tissue samples, stop bleeding or dilate narrowed regions of the upper GI tract.
Colonoscopy is a medical procedure during which a long flexible tube is inserted into the colon. It is used for the evaluation of change in bowel habits, chronic diarrhea, rectal bleeding, abdominal pain, or anemia. During this procedure you will be sedated, so you will need a family member or a friend to drive you home afterward. It is the best screening tool for the detection of colon polyps and colon cancer.
Understanding Percutaneous Endoscopic Gastrostomy (PEG):
Percutaneous endoscopic gastrostomy is a procedure through which an endoscope is used to place a flexible feeding tube through the abdominal wall into the stomach. It is used for administration of nutrition, fluids and medications in patients who cannot swallow safely. This is a hospital based procedure.
Understanding Endoscopic Retrograde Cholangiopancreatography (ERCP):
ERCP is a procedure in which a specialized endoscope is inserted through the mouth into the duodenum where the pancreatic and bile ducts empty. Instruments are passed into the ducts to remove stones, sample tissue, and/or relieve obstruction. This is a hospital based procedure.
Understanding the Video Capsule Endoscopy:
Capsule endoscopy is a disposable miniature video camera contained in a capsule that utilizes a complete optical system with a video chip, light source, transmitter, and energy source designed specifically for direct imaging of the small intestine. It is swallowed by the patient delivering high quality color images in a painless and non-invasive manner. Images are transmitted to a recording device worn around the patient’s waist. After 8 hours, the data is downloaded to a computer workstation, where the images are reviewed by the physician.
