Upper Gastrointestinal Endoscopy

An upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a procedure used to determine the cause of gastrointestinal disorders and symptoms including heartburn, Barrett's esophagus, the presence of hiatal hernias, the cause of abdominal pain, unexplained anemia, and the cause of swallowing difficulties, upper GI bleeding, and the presence of tumors or ulcers. An upper endoscopy lets your doctor examine the lining of the upper part of your gastrointestinal tract, which includes the esophagus, stomach and duodenum (first portion of the small intestine).

This procedure is the best option for a physician to determine the cause of bleeding in the upper gastrointestinal tract, and it is also more accurate than an x-ray for detecting inflammation, ulcers and tumors of the esophagus, stomach and duodenum. Your doctor might use upper endoscopy to obtain a biopsy (small tissue samples) to distinguish between benign and malignant (cancerous) tissues.

Colonoscopy

A colonoscopy is a visual examination of the entire large intestine, also known as the colon. This exam is used to explore possible causes of abdominal pain, rectal bleeding, chronic constipation, chronic diarrhea and other intestinal problems. A colonoscopy is also used as a method of screening for colon cancer.


A gastroenterologist (GI) uses a lighted, flexible tube called a colonoscope that has a small video camera attached to the tip, allowing the GI doctor to view the inside of the entire colon. GI doctors can also sample tissue and/or remove polyps in the colon during a colonoscopy.


Men and women who are at average risk for colon cancer are advised to schedule regular colonoscopies starting at age 50 (age 45 for African Americans), and continue to get a colonoscopy at 10-year intervals thereafter to screen for colon cancer. Patients who have a family history of colon cancer, have inflammatory diseases such as inflammatory bowel disorder (IBD) or other risk factors for colon cancer may be advised to be screened earlier or at increased frequency.
