Gastrointestinal

The gastrointestinal tract starts with the mouth and proceeds to the esophagus, stomach, duodenum, small intestine, large intestine (colon), and rectum and to the anus. Based on the recommendation of your physician, Somerset Ambulatory Surgical Center performs a range of gastrointestinal procedures on an outpatient basis, including:

  • Gastroscopy - examines the inside of the gullet, stomach and duodenum; detects damage to the lining of the esophagus (gullet) or stomach, and ulcers in the stomach or duodenum (small intestine)
  • Colonoscopy - examines the colon and rectum; detects inflamed tissue, ulcers, and abnormal growths
  • Esophagogastroduodenoscopy (EGD) - examines the lining of the esophagus, stomach, and upper duodenum
  • Flexible sigmoidoscopy (Flex Sig) - examines the colon and rectum; detects inflamed tissue, abnormal growths, and ulcers; used to look for early signs of cancer and can help doctors diagnose unexplained changes in bowel habits, abdominal pain, bleeding from the anus, and weight loss
  • Upper GI endoscopy - examines the interior lining of the esophagus, stomach, and duodenum (small intestine); detects ulcers, inflammation, tumors, infection, or bleeding
