Esophageal Motility Disorders in Systemic Diseases Scleroderma

Esophageal involvement is found in more than half of patients with systemic sclerosing diseases. Peristalsis and LES tonus are markedly diminished, allowing reflux of corrosive gastric juice. Other causes of impaired esophageal motility are diabetes mellitus, renal failure, neuropathies, and myopathies.

The LES shows a normal resting pressure with adequate relaxation in response to swallowing (from: Hahn and Riemann, Klinische Gastroenterologie. Vol. I, 3 rd ed.
