Assessment of pneumatic balloon dilation in patients with symptomatic relapse after failed Heller myotomy: a single center experience

ABSTRACT

Background: Although Heller myotomy is one of the most effective treatments for achalasia, it may be associated with early or late symptom relapse in some patients. Therefore, additional treatment is required to achieve better control of symptoms. Aim: To evaluate the safety and efficacy of pneumatic balloon dilation [PBD] in patients with symptom relapse after Heller myotomy
