In this condition, the lower esophageal sphincter (LES) is hypertensive (a state of increased contraction pressures).
Hypertensive lower esophageal sphincter could be isolated (no known cause) or associated with gastroesophageal reflux disease (GERD).
Dysphagia (difficulty swallowing), chest pain, heartburn and regurgitation are the most common symptoms of hypertensive lower esophageal sphincter. The symptoms usually progress slowly with time.
Medical treatment includes aggressive treatment of reflux disease in patients with GERD. Endoscopic treatment for hypertensive LES involves Botox® injections to relax the sphincter. Surgical treatment for symptomatic patients with hypertensive LES needs to be individualized based on associated findings such as hiatal hernia or esophageal dysmotility.
In patients with isolated hypertensive LES, a myotomy (cutting the muscle) to relieve dysphagia, regurgitation and chest pain, and a fundoplication to prevent reflux, may be needed for a selected group of patients. The procedure can be performed by a minimally invasive approach. Follow this link to learn more about laparoscopic myotomy and Dor fundoplication.
In patients with gastroesophageal reflux disease and a hiatal hernia, repair of the hernia and a fundoplication may be necessary for relief of the symptoms of dysphagia, regurgitation and chest pain in a selected group of patients. The procedure can be done via a minimally invasive approach.
