Interventional GI

Center for Interventional Endoscopy

At Mount Sinai Doctors - Bellmore, Interventional GI, we provide comprehensive diagnostics and treatment for a range of digestive diseases and conditions, in a safe, convenient location. Patients no longer have to visit the city for the treatment of their complicated pancreas and biliary problems, or endoscopic management of complex gastrointestinal (GI) disorders.

What is Endoscopy?

An endoscope is a small, flexible tube that can be used to diagnose and treat numerous GI concerns. With endoscopy, doctors can diagnose conditions, clear blockages, remove cysts or stones, or remove tumors without invasive surgery. This results in less discomfort and a shorter recovery time for the patient. Endoscopic procedures can be performed on an outpatient basis, making them convenient for patients.

At Mount Sinai Doctors - Bellmore, Interventional GI, conditions we diagnose and treat include:

  • Colon polyps and cancer
  • Other GI cancers (such as cancers of the pancreas, esophagus, bile ducts, stomach, bowel and liver)
  • GI bleeding and tumors
  • Barrett’s Esophagus, GERD (gastroesophageal reflux disease), and precancerous lesions
  • Pancreatic cysts and chronic pancreatitis
  • Dysphagia (difficulty or discomfort in swallowing)
  • Anemia and occult bleeding
  • Gallstones
  • Obstructions, tumors, and polyps
  • Fluid leaks or buildup

Offering the Latest Technology

Our center offers advanced procedures and uses the latest technology to diagnose and treat digestive diseases and conditions. Some of the advanced technologies we offer are:

The Spyglass Visualization system, which allows our physicians to view the pancreas and bile ducts with a precision never achieved before—providing more reliable diagnosis and minimally invasive treatment.

The Confocal Laser Endomicroscope,
which provides enhanced images of the digestive tract to detect and treat GI cancers at their earliest stages.

Radiofrequency Ablation, a technique that uses thermal energy to destroy cancerous and precancerous tissue, and is an effective treatment for Barrett’s Esophagus, bile ducttumors, pancreatic cysts and radiation proctitis.

Endoscopic Submucosal Dissection (ESD) and Endoscopic Mucosal Resection (EMR),
which represent major advances in treating Barrett’s Esophagus and early GI cancers. Endoscopists inject fluid to elevate the lesion, then cut away the surrounding tissues to remove it.

Cryotherapy, or tissue-freezing, a procedure that addresses a variety of lesions in the digestive tract.

DNA analysis of tissue samples (Fluorescent In Situ Hybridization, or FISH) which helps to evaluate strictures,or abnormal narrowing, of the bile duct.

Stretta and Transoral Incisionless Fundoplication (TIF) for treatment of gastroesophageal reflux disease (GERD).
