Who is Dr. D'souza, Gastroenterologist in New York, NY?
As an interventional gastroenterologist, my expertise is in helping people with various diseases of the pancreas and the bile duct and those with benign and cancerous tumors of the gastrointestinal (GI) tract. Advances in technology have greatly expanded our ability to endoscopically address these, and various other GI diseases. My specific interest is in endoscopic surgery which includes minimally-invasive techniques that do not leave external scars and are often outpatient procedures. This includes removing large benign and precancerous tumors and, in some cases, the removal of early cancers of the GI tract. I also offer minimally-invasive options for certain motility disorders of the esophagus and stomach.
