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. 

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.
