Cholinergic stimulation of the lower esophageal sphincter in patients with vagotomy and antrectomy.

Abstract

Recently cholinergic stimulation of the lower esophageal sphincter (LES) with bethanechol has been shown to be effective in the treatment of chronic gastroesophageal reflux. Since chronic reflux and esophagitis also occur in patients with vagotomy and antrectomy, we studied the effect of bethanechol on sphincter pressure in 10 patients who had had vagotomy and antrectomy. Both subcutaneous (0.08 mg/kg) and oral (25 mg) administration of bethanechol caused significant increases in LES pressure in these patients. In addition, both subcutaneous and oral administration of bethanechol elevated hypotensive sphincter pressures to normal levels. Orally administered bethanechol produced a sustained increase in LES pressure throughout a 90-min study period. These studies suggest that cholinergic stimulation of the LES with bethanechol may be of therapeutic benefit in vagotomized and antrectomized patients with gastroesophageal reflux.
