Gastroenterology | Gastroenterology


Gastroenterology is the branch of medicine whereby the digestive system and its disorders are studied. The name is a combination of three Ancient Greek words gaster (gen.: gastros) (stomach), enteron (intestine), and logos (reason).

Diseases affecting the gastrointestinal tract, which includes the organs from mouth to anus, along the alimentary canal, are the focus of this specialty. Physicians practicing in this field of medicine are called gastroenterologists.

Upon evaluation, it may be determined that an examination of the gastrointestinal (GI) tract is necessary. Often this can be done on an outpatient basis at the Medical Arts Same Day Surgery GI Lab.

Lower GI Endoscopy-Colonoscopy: allows visualization of the lower gastrointestinal tract. It is a procedure used to get a better look at the colon if a person were having symptoms of a lower GI problem, and to screen for colon cancer. A sigmoidoscopy can also be done if it is determined that it is not necessary to view the entire colon.

When having a Lower GI Endoscopy, it is important to follow the preparation instructions. A clean colon is essential for visualizing and removing polyps or flat lesions that may exist.

According to the American Cancer Society:

The death rate (the number of deaths per 100,000 people per year) from colorectal cancer has been dropping in both men and women for more than 20 years. There are a number of likely reasons for this. One is that polyps are being found by screening and removed before they can develop into cancers. Screening is also allowing more colorectal cancers to be found earlier when the disease is easier to cure. In addition, treatment for colorectal cancer has improved over the last several years. As a result, there are now more than 1 million survivors of colorectal cancer in the United States.

Please see: Specialty: Oncology: CancerCare Center: Colorectal Cancer Awareness, on the Trinity Health website for additional information regarding colorectal cancer screening.

Upper GI Endoscopy-Esophagastroduodenoscopy: allows visualization of the upper GI tract. It is a procedure used to get a better look inside the upper gastrointestinal tract if a person were having symptoms of an upper GI problem.

During these procedures, a long flexible tube called an endoscope is used. This instrument has a strong light and a camera on it allowing the physician to visualize the gastrointestinal tract. Certain problems can be treated through instrument channels on the endoscope.
