Procedures We Perform

Our treatments for digestive tract, liver and pancreas disorders are highly individualized. Our physicians tailor the care to each patient’s particular disease and the type and severity of the symptoms.

We also offer a broad range of diagnostic and interventional endoscopy modalities, therapeutic endoscopy procedures and swallowing disorder tests, including:

EGD (Esophagogastroduodenoscopy)
In this test, we pass a flexible videoscope through the mouth to examine the esophagus, stomach and duodenum. This enables us to evaluate disorders of the esophagus, ulcer disease and abdominal pain.

Flexible Sigmoidoscopy
During this procedure, we pass a flexible videoscope through the rectum to evaluate the anus, rectum and distal descending colon. This enables us to evaluate the distal colon for bleeding from causes such as hemorrhoids.

With this test, we pass a flexible videoscope through the rectum to evaluate the anus, rectum and the colon or large bowel. We use this procedure to evaluate the colon for bleeding, polyps and colon cancer.

Esophageal Motility Test
During this test, we pass a small catheter through the nose and into the esophagus to evaluate the motility of the esophagus, that is, its power to move spontaneously. We can examine the esophagus for motility disorders that contribute to swallowing problems.

ERCP (Endoscopic Retrograde Cholangiopancreatography)
Due to factors related to diet, environment and heredity, the bile ducts, gallbladder and pancreas become the seat of numerous disorders that can cause a variety of symptoms. The ERCP test helps in diagnosing and often in treating these conditions.

This procedure involves using a flexible video endoscope to inject dye into the patient's bile and pancreatic ducts. Then we take X-rays to outline the bile ducts and pancreas, and to identify problem areas.

We also use the ERCP test to treat or diagnose:
• Blockage of the bile duct
• Cancer of the bile ducts or pancreas
• Gallstones trapped in the main bile duct
• Pancreatitis (inflammation of the pancreas)
• Undiagnosed upper-abdominal pain
• Yellow jaundice

In addition, our specialists employ other sophisticated diagnostic tools, such as the SmartPill capsule, an ingestible medical device used to evaluate the GI tract.


Advanced Services

The division features the Irritable Bowel Syndrome (IBS) Program, which is dedicated to diagnosing IBS, one of the most common GI disorders in the US, and helping patients achieve relief from their symptoms. Another notable initiative is the Hepatitis C Program.

The Center for GI and Motility Disorders treats many gastrointestinal disorders, including those that affect the esophagus, stomach, small intestine, large intestine, and pelvic floor regions. We treat the following disorders: 


  • Esophagus region
    • Reflux disease (exposure of esophagus lining to stomach contents)
    • Dysphagia (difficulty swallowing)
    • Chronic cough or voice changes related to reflux disease
  • Stomach region
    • Gastroparesis (slow gastric emptying)
    • Dumping Syndrome (rapid gastric emptying)
    • Functional Dyspepsia (uncomfortable fullness; burning or pain)
  • Small intestine region
    • Chronic Intestinal Pseudo-Obstruction (inability of the intestines to push food through that mimics intestinal obstruction but without any lesion in the intestinal lumen)
    • Intestinal Dysmotility (abnormal intestinal contractions, such as spasms and intestinal paralysis)
  • Large intestine region
    • Refractory Constipation (slow transit or disorders of evacuation)
    • Irritable Bowel Syndrome or IBS (symptoms of chronic abdominal pain or discomfort associated with an altered bowel habit )
  • Pelvic floor
    • Disorders of evacuation
    • Pelvic dyssynergia
    • Fecal Incontinence (loss of bowel control)

Cutting-Edge Research

Members of the Division of Gastroenterology and Liver Disease are on the faculty of Icahn School of Medicine at Mount Sinai and are on staff at Mount Sinai St. Luke's and Mount Sinai West's Department of Medicine. They are committed to participating in leading-edge research projects at these institutions.

For example, our specialists have been involved in the following research programs:
• The Effect of Aging Upon Gastrointestinal Function
• Colon Cancer Prevention -- Use of Chemopreventive Agents
• AIDS and the Gastrointestinal Track
