Reversal of lower esophageal sphincter hypotension and esophageal aperistalsis after treatment for hypothyroidism
A 65-year-old woman suffered from both chronic gastroesophageal reflux, which was complicated by columnar metaplasia (Barrett's epithelium), and profound hypothyroidism. An esophageal motility tracing showed absence of peristalsis in the lower esophagus and the lower esophageal sphincter (LES) could not be identified. Thyroid replacement therapy, in conjunction with antacid and cimetidine treatment, was associated not only with improvement in the gastroesophageal reflux symptoms, but also with a return of esophageal peristalsis and LES pressure to normal. To support our clinical observations, we rendered four cats hypothyroid with /sup 131/I and documented a fall in LES pressure. We propose that abnormal smooth-muscle function of the esophagus may be another manifestation of the gastrointestinal motility disturbances which are associated with hypothyroidism.
