New GI Motility Program at Capital Health

A Focus on Muscles of the Digestive System

Muscles within the walls of your digestive system move your food through the digestive tract when you eat. If these muscles aren’t working properly, it can cause a wide range of problems that are very complicated to diagnose and treat.

Capital Health has a new Gastrointestinal (GI) Motility Program as part of its Center for Digestive Health that combines advanced technology with specialized medical expertise to diagnose and treat these complex issues. Dr. Douglas Weinstein, a board certified, fellowship trained gastroenterologist with a focus on GI motility disorders, now leads the new program, which is located at Capital Health Medical Center – Hopewell.

“For people suffering from GI motility disorders, finding answers used to mean having to travel somewhere outside of our region for more advanced testing and treatment options. Our new program brings this same high level of experience and expertise here to patients and referring physicians in the Mercer, Burlington, and Bucks County community,” said Dr. Douglas Weinstein, director of the GI Motility Program at the Capital Health Center for Digestive Health.

The GI Motility Program is part of the wide range of advanced GI services available at the Capital Health Center for Digestive Health, which offers initial consults, testing, procedures, and follow-up appointments, all in one convenient location at Capital Health Medical Center – Hopewell.

What Does the GI Motility Program Treat?

Our expert team of endoscopists, surgeons, radiologists, dietitians and physical therapists offers testing and treatment for:

  • Dysphagia (ineffective swallowing)
  • Gastroesophageal reflux disease (GERD)
  • Achalasia (ineffective movement of food from the lower esophagus to the stomach)
  • Gastroparesis (ineffective movement of food from the stomach to the small intestine)
  • Fecal incontinence (inability to control bowel movements)
  • Refractory Constipation (constipation not improving with standard treatment)
  • Pelvic floor dyssynergia (impaired coordination of muscles in the lower digestive tract)

What Do We Use to Diagnose/Treat GI Motility?

Our highly trained specialists use state-of-the art technology to help patients and their referring physicians plan the best course of treatment.

  • The Enterra® neurostimulator uses electrical impulses to regulate muscles of the stomach wall and reduce the symptoms of gastroparesis
  • High resolution esophageal manometry helps determine if motility problems exist in the esophagus. Via a small tube passed through the nose into the esophagus, measurements of esophageal function are taken based on pressure readings.
  • The Endolumenal Functional Lumen Imaging Probe, or EndoFLIP, complements the manometry to give even more detail in patients who have complex conditions of the esophagus and stomach.
  • 24- and 48-hour pH and impedance testing helps determine if the patient needs to be on acid-blocking medication and if surgery or endoscopic reflux procedures can help.
  • An esophagram is a fluoroscopic test that allows our radiologists to capture images of the esophagus while it is functioning.
  • Nuclear medicine testing can be used to determine the time it takes for the stomach, intestine and colon to move a meal through the body.

What is Enterra® Neurostimulation?

Gastroparesis is a condition that is common among people with diabetes that slows or stops the movement of food from the stomach to the small intestine. Capital Health is one of only a few hospitals in New Jersey to offer the Enterra® neurostimulator, a state-of-the-art treatment that uses electrical impulses to stimulate or regulate muscles of the stomach wall to get them working properly (similar to how a pacemaker works in the heart). In addition to an overall better quality of life, the Enterra® device can improve function of the muscles in the stomach wall, which allows for better nutrition for those who are malnourished as a result of their gastroparesis.
