Gastroenterology

Our board-certified gastroenterologists are here for you.

At CoxHealth, our board-certified gastroenterologists specialize in preventing, diagnosing and treating disorders of the pancreas, liver, gallbladder, esophagus, stomach, small intestine and colon. With the latest advances in endoscopic equipment and minimally invasive capabilities, our physicians diagnose, treat and help manage your condition. Endoscopes (tubes with cameras) are used to look at and perform biopsies on different parts of the gastrointestinal (GI) tract, such as the esophagus, stomach, small intestine, bile ducts and colon.

We use the latest diagnostic procedures, including:

  • Capsule endoscopy - This is a test done to take pictures of your digestive tract. It uses a capsule with a tiny camera in it. 
  • Colonoscopy - A colonoscopy is a test to view the inside of your lower digestive tract (colon and rectum). This test is done to help look for colon cancer.
  • Endoscopic ultrasound - This test looks at the inside of your GI tract.  It's commonly used to look for cancers or growths in the esophagus, stomach, pancreas, liver, and rectum.
  • ERCP - This procedure is used to view the biliary and pancreatic ducts. It is used to check diseases that affect the biliary and pancreatic ducts. It can also help find and treat any blockages.
  • pH monitoring - This involves monitoring pH (acid levels) to evaluate acid reflux and other digestive disorders.
  • Upper GI endoscopy - An upper GI endoscopy lets your healthcare provider look right into the beginning of your gastrointestinal (GI) tract. The esophagus, stomach, and the first part of the small intestine (the duodenum) make up the upper GI tract. 
  • Esophageal manometry - This tests measures the strength and function of the esophagus (the “food pipe”). Results can help find causes of heartburn, swallowing problems, or chest pain.
  • Double balloon enteroscopy - This test uses a special tube (scope) to get deep into the small intestine. 

If you’re scheduled for a procedure, please carefully follow the preparation instructions you received. Don’t hesitate to call us if you have questions.
