Diagnostic procedures and treatments offered by St. Charles Gastroenterologists include:

Endoscopy: During an endoscopy, a physician inserts a thin flexible tube into the patient’s GI tract. There is a fiberoptic camera within the tube which allows the physician to check for polyps, ulcers and other abnormalities. Endoscopy is a core procedure in Gastroenterology and the specialists at St. Charles have more than 30+ years of experience with this procedure.

Upper Endoscopy: This is a specific type of endoscopy that examines the upper GI tract exclusively: the mouth, throat esophagus, and stomach. Physicians gather tissue samples and check for bacterial growth, polyps, tears and more. An upper endoscopy can help physicians to diagnose conditions or problems associated with heartburn, indigestion, swallowing issues, nausea and vomiting and much more.

Barium Swallow Test: This is an imaging procedure in which patients swallow Barium, a liquid material, prior to an X-Ray to highlight areas of their GI tract on the X-Ray image. St. Charles gastroenterologists use barium swallow tests to evaluate patients for dysphagia (difficulty swallowing), narrowing of the esophagus, ulcers, tumors, Gastroesophageal reflux disease (GERD), and more.

Radiofrequency Abelation for Barrett’s Esophagus: Radiofrequency abelation is a procedure in which a physician uses radio waves to remove diseased tissue from the esophagus of patients diagnosed with Barrett’s esophagus, a condition in which repeated, long-term exposure to GERD has altered the tissue of the esophagus to resemble that of the intestine. Gastroenterologists at St. Charles are among a select few on Long Island performing radiofrequency abelation procedures with the Barrx™ system, a cutting-edge tool for removing cancerous, precancerous and diseased tissue from the esophagus with a high level of precision.  

Breath Test: In this non-invasive procedure, patients breath into a device which detects and measures gases linked to lactose intolerance, fructose intolerance, and bacterial growth in the GI tract.

Gastroenterology specialists from St. Charles perform diagnostic procedures and treatments in an office setting, as well as in the technologically equipped suites at St. Charles Hospital.
