  • Endoscopy
    Endoscopy is a minimally invasive diagnostic medical procedure that is used to assess the interior surfaces of an organ by inserting a tube into the body. The instrument may have a rigid or flexible tube and not only provide an image for visual inspection and photography, but also enable taking biopsies and retrieval of foreign objects. Endoscopy is the vehicle for minimally invasive surgery and patients may receive conscious sedation so they do not have to be consciously aware of the discomfort.  Many endoscopic procedures are considered to be relatively painless and, at worst, associated with moderate discomfort.
  • Gastroenterology
    A Gastroenterologist works with patients to treat, control, and manage a wide range of conditions. Some of the many conditions diagnosed and treated by Gastroenterologists include acid reflux disease, hemorrhoids, hepatitis, ulcers, hernias, and many more. Gastroenterologists must be able to diagnose the signs and symptoms of all digestive diseases and perform all the appropriate diagnostic tests.
