Our Gastroenterology Services

Conditions Treated


  • Esophagogastroduodenoscopy or Endoscopy (EGD): performed to examine the eosphagus, the gastroesophageal junction and the stomach, especially to diagnose the presence and severity of erosive esophagitis
  • Radiofrequency ablation (RFA) therapy (also known as HALO): minimally invasive endoscopic procedure to treat Barrett’s Esophagus
  • 48-hour esophagus acid monitoring: provides a way to measure the severity of acid exposure in the esophagus
  • Esophageal manometry: outpatient test performed to identify problems with movement and pressure in the esophagus that may lead to problems like heartburn
  • Transoral incisionless fundoplication (TIF)
  • Fundoplication surgery for GERD
  • Upper gastrointestinal endoscopy: procedure to see the lining of your upper GI tract
  • Upper gastrointestinal (UGI) series (also known as Barium Swallow or Esophagram): a group of X-rays that look at your esophagus, stomach, and the first part of your small intestine to diagnose anatomic abnormalities, such as a hiatal hernia, blockages, inflammation of the esophagus, and free reflux. It is primarily used to rule out esophageal disorders like achalasia.  A barium swallow involves ingesting a solution that can be seen on X-ray. A round tablet of barium may be given to allow observation of the movement of the esophagus during the act of swallowing.
  • Percutaneous endoscopic gastrostomy: a tube is inserted into your stomach through the abdominal wall to provide a way of feeding when oral intake isn’t working
  • Endosurgical therapy (EMR)
  • Colon examinations (Colonoscopy, Sigmoidoscopy, Anoscopy, Proctoscopy): performed to look inside your colon for ulcers, polyps, and abnormal cells
