Digestive Diseases

Our gastroenterologists at the New York-Presbyterian Allen Hospital provide non-surgical treatment for adults with a wide range of gastrointestinal disorders in our advanced, newly renovated, state-of-the-art facility. We provide a wide variety of expertise—ranging from the management and palliation of advanced gastrointestinal tumors and pancreatic cysts, to the medical care of chronic illnesses such as GERD (gastroesophageal reflux), H. pylori infection, ulcers, hepatitis/liver disorders, gallstones, colon polyps, and inflammatory bowel diseases (such as Crohn's disease and ulcerative colitis). As full-time faculty at Columbia University College of Physicians and Surgeons, we also refer patients to clinical trials and to our world-class surgeons and oncologists.

Our Services

Our modern, latest high-definition endoscopes allow us to detect conditions such as Barrett's esophagus, early removable cancers, and flat polyps in the colon. We offer endoscopic procedures such as:

• Upper endoscopy to evaluate the causes of and provide treatment for numerous symptoms, including abdominal pain, dysphagia (swallowing difficulty), bleeding, nausea, and vomiting; to obtain tissue samples for analysis; and to remove polyps or treat bleeding.
• Colonoscopy to examine the lining of the colon to remove polyps or assess other abnormalities.
• FUSE: Full spectrum endoscopy/colonoscopy, which provides high-definition, wide-angled views of the colon that improve the detection of polyps and lesions.
• Endoscopic ultrasound (EUS), which uses high-frequency sound waves to provide detailed images of the digestive tract and adjacent organs. EUS enables us to characterize pancreatic cysts, stage early cancers, and provide treatments for certain disorders, such as pancreatic pseudocysts.
• Endoscopic retrograde cholangiopancreatography (ERCP) to examine the ducts of the gallbladder, pancreas, and liver and to remove bile duct stones.
  • SpyGlass DS: This single-operator system provides direct views of the bile duct and pancreas, improving tissue sampling and providing a platform for therapies.
  • Radiofrequency ablation (RFA) is a treatment option for inoperable pancreaticobiliary tumors.
• Video capsule endoscopy of the small bowel, which uses a pill-sized camera to examine the inside of the small intestine for sites of bleeding or abnormal growths.
• Endoscopic mucosal resection, which provides the ability to remove large precancerous lesions of the stomach, small intestine, and colon.

Other Services

• Infusion Services: We provide intravenous medications, such as infliximab or vedolizumab, for the treatment of inflammatory bowel disease.
• Open Access/Direct Referral to Procedures: Provides direct scheduling for certain qualified patients for procedures such as colonoscopy, without needing to be seen in the office for a prior consultation. If you are under the age of 75 and do not have other significant illnesses or symptoms, you may qualify.
