GI Tests and Procedures
Diagnostic and Treatment Procedures
Capsule endoscopy is a noninvasive diagnostic imaging device for use in the GI tract. A small capsule with a camera in it is swallowed and moves by natural peristalsis smoothly and painlessly throughout the GI tract, transmitting color video images as it passes. The procedure is ambulatory, allowing patients to continue daily activities throughout the videoscopic examination while wearing a receiver-transmitting device, which they return to be analyzed. This is especially useful in viewing the entire small intestine, which cannot be reached by an endoscopy.
Procedure to look into the rectum and colon through a long, flexible, narrow tube with a light and tiny lens on the end. This tube is called a Colonoscope. Click here to read more on, “Understanding Colonoscopy”.
Endoscopic Retrograde Cholangiopancreatography (ERCP)
ERCP is a procedure that involves inserting an endoscope (viewing tube) through the stomach and into the small intestine. A special dye injected during the procedure shows the ducts in the biliary system. Click here to read more on, “Understanding ERCP”.
Endoscopic Ultrasound (EUS)
EUS is an imaging modality. It is a combination of endoscopy and ultrasound, which uses high frequency sound waves to create an image of internal organs. It plays a role in gastroenterology, surgery and oncology. It is used in staging tumors, diagnosing size and exact location of tumors, diagnosing common bile duct stones and Histologic diagnosis of unresectable tumors. It can be used to treat cancerous lesions in various ways.
Upper GI Endoscopy (Esophagogastroduodenoscopy- EGD)
EGD is an exam of the upper digestive tract using an endoscope.
Esophageal manometry is a diagnostic test that measure the pressure within the esophagus. This test is also effective in evaluating the contraction function of the esophagus. Click here to read more on, "Understanding Esophageal Manometry".
Esophageal pH Test
An esophageal pH test measures the frequency that the lower end of the esophagus is exposed to stomach acid and the degree of acidity during a 24-48 hour period. This is a way to assess patients for GERD (gastro esophageal reflux disease). For the Bravo system, a capsule device is placed in the esophagus and the patient wears a receiver for the 24-48 hours. A diary of any symptoms and activities is kept and then correlated to the data recorded on the transmitter.
Sigmoidoscopy involves looking into the sigmoid colon and rectum with a flexible or rigid tube, called a sigmoidoscope. Click here to read more on, “Understanding Flexible Sigmoidoscopy”.
Photodynamic Therapy (PDT)
PDT involves the administration of a chemical sensitizer that selectively accumulates in areas of tumor with greater concentration than in normal tissue. The chemical is then activated by application of light (at a specific wave length) to the area of the tumor with a low power laser resulting in tumor necrosis by photochemical rather than a thermal effect. PDT is used to treat esophageal cancer.
Remicade Infusion Therapy
Remicade is a medication given intravenously to patients for the treatment and reduction of symptoms of moderately to severely active crohn’s disease who have an inadequate response to conventional therapy. It is done on an outpatient basis over a 3-4 hour period of time.
