Gastroenterology is an area of medicine that focuses on the health of the digestive system, or the gastrointestinal (GI) tract. Gastroenterologists can treat everything from irritable bowel syndrome (IBS) to hepatitis C. These specialists primarily diagnose and treat GI diseases in both men and women. They perform endoscopic procedures, in which they use specialized instruments to view the GI tract and make a diagnosis.
Parts of the GI system include Pharynx, Esophagus, Stomach, Small intestine, Large intestine, Liver, Gallbladder, Pancreas, Salivary glands, Tongue, Epiglottis, Rectum, Anus
Gastroenterology is a specialized area of medicine that focuses on the GI tract. Some possible areas of emphasis are:
- Hepatology, which focuses on the diagnosis and treatment of diseases of the liver, gallbladder, biliary tree, and pancreas
- Pancreatic disease
- Inflammatory bowel disease, or chronic inflammation of your digestive tract
- Gastrointestinal cancer
- Endoscopic surveillance
- Reflux esophagitis, which is commonly due to gastroesophageal reflux disease
These specialists treat a number of conditions affecting the GI system. This can include:
- Acid reflux
- Hepatitis C
- Polyps, or growths, which typically occur in the large intestine
- Jaundice, or a yellowing of the skin
- Bloody stool
- Pancreatitis, or a rare disease causing inflammation of the pancreas
- Colon cancer
These specialists perform a range of nonsurgical procedures. This can include:
- ENDOSCOPY :
Endoscopy is a procedure that uses a tiny wireless camera to take pictures of your digestive tract. The camera sits inside a vitamin-sized capsule that you swallow. As the capsule travels through your digestive tract, the camera takes thousands of pictures that are transmitted to a recorder you wear on a belt around your waist or over your shoulder.
Capsule endoscopy helps doctors see inside your small intestine — an area that isn't easily reached with conventional endoscopy. Capsule endoscopy can be used by adults and by children who can swallow the capsule.
- ERCP :
ERCP is a procedure that enables your physician to examine the pancreatic and bile ducts. A bendable, lighted tube (endoscope) about the thickness of your index finger is placed through your mouth and into your stomach and first part of the small intestine (duodenum). In the duodenum a small opening is identified (ampulla) and a small plastic tube (cannula) is passed through the endoscope and into this opening. Dye (contrast material) is injected and X-rays are taken to study the ducts of the pancreas and liver.
- COLONOSCOPY :
Colonoscopy is an imaging test performed to diagnose any abnormalities or changes in the rectum or the colon (large intestine). It is a minimally invasive procedure. Colonoscopy is done with the help of a colonoscope, which is a flexible, long tube with a tiny video camera placed at the tip of the colonoscope. The colonoscope is inserted into the patient's rectum and the doctor is able to see the in the colon and rectum very clearly. The colonoscope is very flexible in nature and can go through the entire length of the colon. It is a safe procedure that helps in diagnosing various problems at an early stage. It is possible to remove polyps or some other abnormal tissues easily with the colonoscope during the procedure, if needed. Colonoscopy is sometimes combined with biopsies, which are helpful for the doctor to take a biopsy tissue sample from the rectum or colon for further detailed analysis.
- OGD :
OGD is known as oesophago-gastroduodenoscopy. This is an examination of your oesophagus (gullet), stomach and the first part of your small bowel called the duodenum. The instrument used in this investigation is called a gastroscope. It is flexible and has a diameter less than that of a little finger. Each gastroscope has an illumination channel which enables light to be directed onto the lining of your upper digestive tract and another which relays pictures back to the endoscopist onto a television screen. During the investigation, the doctor may need to take some tissue samples (biopsies) from the lining of your upper digestive tract for analysis. A video recording and/or photographs may be taken for your records. The procedure will be performed by or under the supervision of a trained doctor or nurse endoscopist, and we will make the investigation as comfortable as possible for you. Some patients have sedation injected into a vein for this procedure, although others prefer to remain awake and have local anaesthetic throat spray only.
