The Gastrointestinal Motility, Esophageal, and Swallowing Disorders Center

The Gastrointestinal Motility Center (GMC) is a specialized center of excellence located within the Section of Gastroenterology and Hepatology at the Dartmouth Hitchcock Medical Center in Lebanon, New Hampshire.

The Center is staffed by a team of physicians, advanced practice providers, nurses, allied health professionals, and research assistants who have specialized training in the evaluation, diagnosis, and treatment of patients with motility disorders.

Motility disorders may be defined as disorders of the gastrointestinal tract in which the muscle and nerves do not function correctly. Motility disorders are quite common, affect women and men of all ages, and are diagnosed in people of all ages, nationalities, and races. Although the GMC has extensive experience in diagnosing and treating all varieties of motility disorders, some of the most common motility disorders referred for evaluation include the following:

  • Achalasia
  • Chronic intestinal pseudo-obstruction
  • Constipation
  • Diarrhea
  • Dyspepsia
  • Dysphagia (difficulty swallowing)
  • Fecal incontinence
  • Gastroesophageal reflux disease (GERD)
  • Gastroparesis
  • Irritable bowel syndrome
  • Pelvic floor dysfunction (also called pelvic floor dyssynergia)

Gastrointestinal Motility Laboratory

The Gastrointestinal Motility Laboratory is equipped to evaluate and diagnose patients with suspected motility disorders using a number of different specialized tests. These tests include:

  • Assessment of gastric (stomach) function using gastric emptying scans
  • Assessment of pelvic floor function using 3D high-definition anorectal manometry, balloon expulsion testing, and magnetic resonance (MRI) defecography
  • Assessment of small bowel and colon transit using the Smartpill
  • Evaluation for bacterial overgrowth using hydrogen and methane breath tests
  • Measurement of esophageal function using esophageal manometry
  • Measurement of esophageal pH using the BRAVOpH capsule
  • Measurement of esophageal reflux 24 hour combined pH/multichannel intraluminal impedance testing
