The Brooklyn Hospital Center is at the forefront of new technologies in colonoscopy and endoscopy. We have highly advanced endoscopes, which make procedures among the fastest and most effective in New York while greatly minimizing discomfort. We are the first hospital in New York City equipped with the THIRD EYE Retroscope, which gives physicians an advanced retrograde view of the colon, illuminating blind spots and improving polyp detection during colonoscopy.

Our board certified Gastroenterologists are experts in the diagnosis and treatment of complex illnesses of the GI tract. Utilizing an all-digital endoscopy suite and other Brooklyn Hospital Center resources, they’ll help find the cause of your problem and develop a treatment plan that works for you.

  • upper endoscopy – helps diagnose cause of abdominal pain, cause of upper GI bleed and saves lives by enabling control of bleeding, also allows for removal of foreign body impacted in the esophagus

  • colonoscopy – aids in colon cancer screening, enables removal of pre-cancer and early cancer lesions in the colon, helps diagnose and control bleeding in cases of lower GI bleed, and aids in the diagnosis of causes of diarrhea such as infection, inflammatory bowel disease and microscopic colitis

  • endoscopic retrograde cholangiopancreatography (ERCP) – aids in the diagnosis of bile duct disease, saves lives by allowing drainage of infection in patients with ascending cholangitis (infection of the bile duct), and improves quality of life by relieving jaundice and itching in patients with bile duct obstruction from advanced pancreatic cancer

  • endoscopic ultrasound – special endoscopic imaging which  helps in closely visualizing abdominal organs such as pancreas, bile duct and surrounding structures

  • esophageal manometry – helps diagnose and treat motility disorders of esophagus

  • capsule endoscopy – helps diagnose small bowel disease such as blood vessel malformation, colitis and ulcerations

  • colonic stent – prevents obstruction in cases of advanced colon cancer

  • esophageal stent and dilation – improves difficulty in swallowing in patients with strictures and advanced esophageal cancer

Most endoscopies take just 10-20 minutes and overnight stays are rarely required.

Commitment to Education

The Brooklyn Hospital Center is not only Brooklyn’s first hospital; it’s also home to one of the borough’s oldest fully accredited Gastroenterology Fellowship programs. Thanks in part to this long tradition of scholarship and original research, our patients receive the most informed, up-to-date GI treatments available.

We have several Fellows in our fully accredited 3-year Fellowship Program. All of these students are under the supervision of our division chief, full-time gastroenterologists and voluntary specialists.
