Information About Our Procedures:


  • Pill Cam SB- (Small Bowel Capsule Endoscopy)
    Pill Cam SB is the most widely used, patient-friendly tool for directly visualizing the small bowel. Pill Cam SB is a vitamin-sized capsule that once ingested travels through the small bowel taking video images that help the physician detect the source of obscure bleeding, iron deficiency anemia and Crohn’s disease. This test is performed in the physician’s office.
  • Radiofrequency Ablation Halo for Barrett’s Esophagus (HALO)
    If a patient is diagnosed with Barrett’s Esophagus and the biopsies contain areas of dysplasia, Radiofrequency Ablation therapy is performed to treat this issue. Ablation is a technique where tissue is heated until it is no longer viable or alive; The HALO ablation technology is a very specific type of ablation, in which heat energy is delivered in a precise and highly-controlled manner. HALO ablation therapy is performed in conjunction with an upper endoscopy (EGD). The treatment is performed in an outpatient setting and no incisions are involved.
  • Breath Test (UBT)
    The BreathID® Test is an easy, 10 minute test. You breathe normally after you are connected to a nasal breathing cannula. The BreathID® System automatically samples your breath, before and after you are given a 5 ounce solution to drink. Testing time is around 10 minutes, and the results are immediate.
    Your symptoms may be caused by a common bacterial infection called Helicobacter pylori (H.pylori). H.pylori affects nearly 1 in 3 Americans. It can cause common symptoms like heartburn, nausea, and bloating. It also is what causes up to 90% of stomach ulcers. If left untreated, it can sometimes lead to painful stomach inflammation, severe ulcers and, in some cases, can increase the risk of gastric cancer.
  • Ultrasound
    An ultrasound exam is a diagnostic technique used to evaluate internal body structures. Grey scale images are produced by high frequency sound waves which differentiate the shapes if various tissues and organs in the body. These images are generally referred to as a two dimensional (2D) image and/or B scan. We employ a certified licensed sonographer to perform these tests in our office.

  • SIBO Testing
    A noninvasive 2-3 hour breath test done in our office to diagnose if a patient has SIBO,

    Small intestinal bacterial overgrowth. SIBO is a serious condition affecting the small intestine. Excess bacteria in the small intestine can lead to the release of the gases hydrogen and methane, which can be identified through a breath test. It occurs when bacteria that normally grow in other parts of the gut start growing in the small intestine.

    SIBO symptoms mainly affect the gut. They may include:
    • pain in the stomach, especially after eating
    • bloating
    • cramps
    • diarrhea
    • constipation
    • indigestion
    • regular feeling of fullness
    • gas
