Comprehensive Care for Gastrointestinal Disorders
Catholic Health's board-certified gastroenterologists offer excellence in care for Long Islanders who need nonsurgical and surgical treatment for gastrointestinal (GI) disorders. We treat common conditions like irritable bowel syndrome (IBS) and perform colonoscopy and endoscopy procedures. Our surgeons are experts in complex procedures like a colon resection.
We are also experts in treating GI disorders in children.
St. Francis Hospital & Heart Center® (Roslyn, NY) is ranked by U.S. News & World Report as one of the best hospitals in the nation for gastroenterology and gastrointestinal surgery.
All Catholic Health hospitals offer colonoscopy and endoscopy procedures, both for hospitalized patients and on an outpatient basis, at facilities across Long Island.
Our gastroenterologists use advanced technology to diagnose and treat even the most difficult disorders affecting the GI system in areas including your esophagus, stomach, small bowel, colon, gallbladder, liver, pancreas and bile ducts.
Colonoscopy and endoscopy procedures are commonly used diagnostic tools and critical to early detection of cancers including esophageal and colorectal.
A team of board-certified gastroenterologists and anesthesiologists, as well as registered nurses and support staff, deliver the highest quality and safest care to patients.
An endoscopy, a procedure used to diagnose and treat digestive system issues, helps identify issues in your digestive tract. The procedure is performed using a flexible tube with a tiny camera that sends images to a video screen. The images allow your physician to check for polyps, ulcers and other abnormalities in your digestive tract. During an endoscopy, the scope is able to take tissue samples, remove polyps and perform other exams.
One of the newest types of endoscopy is capsule endoscopy. This is a vitamin-sized capsule that contains a tiny video camera. After you swallow the capsule, the camera takes thousands of images of your entire small intestine, including parts that other types of endoscopy can’t reach. Capsule endoscopy can help physicians diagnose causes of gastrointestinal bleeding and disorders such as Crohn’s disease.
Upper endoscopy—also called gastroscopy—is used to diagnose and treat gastrointestinal conditions affecting the upper digestive system. This includes the esophagus, stomach and small intestine. Conditions such as abdominal pain, gastrointestinal bleeding, unexplained weight loss and swallowing problems may be diagnosed with an upper endoscopy.
A thin, flexible tube with a camera is inserted through your mouth. The camera allows your physician to see your upper digestive system. The procedure is painless and done under a light sedative. It typically takes 10 to 15 minutes.
A colonoscopy allows your physician to see inside the colon and large intestine using a flexible tube called a colonoscope that is inserted through the rectum while the patient is sedated. Colonoscopies help detect abnormalities, such as inflamed tissues, polyps and ulcers, and help diagnose the cause of gastrointestinal bleeding, chronic diarrhea, chronic constipation or unexplained weight loss.
Colonoscopies are a common screening tool for colorectal cancer.
Flexible sigmoidoscopy is used to diagnose conditions affecting the lower part of the large intestine or the sigmoid colon. It's sometimes used as a screening tool for colon cancer. During the procedure, a thin, flexible tube with a camera is inserted through your rectum.

Understanding and Treating GERD
Heartburn and Gastroesophageal Reflux Disease (GERD) is a common chronic condition that involves acid from the stomach flowing back into the esophagus because of the malfunctioning of the lower esophageal sphincter—the muscular valve that closes after food enters the stomach.
Symptoms of heartburn and reflux disease can include:
- Acid reflux
- Persistent regurgitation
- Difficulty swallowing
- Chronic cough
- Chest pain
