The Motility Center is a specialized center of excellence located within the Division of Gastroenterology & Hepatology of the Dartmouth-Hitchcock Medical Center. The center is staffed by physicians, nurse practitioners, nurses, 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 Motility Center has extensive experience in diagnosing and treating all varieties of motility disorders, some of the most common motility disorders referred for evaluation include: achalasia, dysphagia (difficulty swallowing), gastroesophageal reflux disease (GERD), dyspepsia, gastroparesis, constipation, Hirschsprung's disease, diarrhea, irritable bowel syndrome, chronic intestinal pseudo-obstruction, and pelvic floor dysfunction (also called pelvic floor dyssynergia).
The Motility Center is equipped to evaluate and diagnose patients with suspected motility disorders using a number of different specialized tests. These tests include: measurement of esophageal pH using the Bravo capsule; measurement of esophageal function using esophageal manometry and impedance testing; assessment of gastric (stomach) function using gastric emptying scans and electrogastrography (EGG); measurement of upper gastrointestinal tract motility using antroduodenal manometry; evaluation for bacterial overgrowth using hydrogen breath tests; and the assessment of colorectal function using sitz marker studies, anorectal manometry, and MRI defecography.
