Long‐term outcome following pneumatic dilatation as initial therapy for idiopathic achalasia: an 18‐year single‐centre experience

Abstract

Long-term relapse is common following pneumatic dilatation. While on-demand pneumatic dilatation for relapse yields a good response, one-third of relapsers neither seek medical attention nor receive interval therapy. Close follow-up with timely repeat dilatation is necessary for a good long-term outcome. Given the poor predictive value of chest pain for perforation, routine gastrografin swallow is recommended postdilatation.
