Abstract

Achalasia is a condition of unknown etiology. It represents a motor disorder of the esophagus characterized by absent or incomplete relaxation of the lower esophageal sphincter upon swallowing and by non-propulsive swallow-induced contraction waves or amotility of the esophageal body. Dysphagia and regurgitation of ingesta are the most frequent symptoms. Medical treatment, i.e. by calcium-channel blockers and nitric oxide donors, may be tried in patients with mild dysphagia or in elderly patients but rarely yields adequate symptom relief. Mechanical dilatation of the achalasic sphincter may be performed as an initial treatment option. Intrasphincteric injections of botulinum toxin seemed to be a promising alternative, but it has become obvious that, in most cases, repeated applications of the toxin are required to maintain patients symptom-free. Myotomy of the achalasic sphincter with or without fundoplication to prevent gastroesophageal reflux, is employed mainly in patients in whom dilatations have failed, but since the introduction of minimally invasive surgery, myotomy has become the primary treatment at many centers. This article aims to provide an overview of the development of the conservative and surgical treatment of a...Continue Reading
