 Gastroenterologists
are physicians specially trained in the management of disorders of the digestive system. The major
organs they treat include the mouth, esophagus, stomach, duodenum,
small intestine, colon and rectum.
Among
the many conditions a Gastroenterologist investigates and treats
are swallowing difficulties, narrowing of the esophagus, hiatus hernia,
ulcers of the stomach and duodenum, cancer of the stomach and pancreas,
disorders of the liver and gallbladder, diverticulitis, polyps, ulcerative
colitis, irritable bowel syndrome, cancer of the colon and hemorrhoids.
Work of Gastroenterologists has been dramatically changed in recent years by
the development of fiber optic endoscopes. Much of the gastrointestinal tract
can now be visualized directly by these instruments and samples can be taken
for laboratory examination. Non-invasive procedures such as CAT and MRI scanning
have also greatly increased the diagnostic abilities of Gastroenterologists.
