Abstract

Introduction: Achalasia is a rare esophageal motility disorder characterized by abnormal esophageal peristalsis and the inability of the lower esophageal sphincter to relax, resulting in poor esophageal emptying. This can be relieved by endoscopic and surgical treatments; each comes with certain advantages and disadvantages. Areas covered: This review aims to guide the clinician in clinical decision making on the different treatment options for achalasia regarding the efficacy, safety, and important predictors. Expert opinion: Botulinum toxin injection is only recommended for a selective group of achalasia patients because of the short term effect. Pneumatic dilation improves achalasia symptoms, but this effect diminishes over time and requiring repeated dilations to maintain clinical effect. Heller myotomy combined with fundoplication and peroral endoscopic myotomy are highly effective on the long term but are more invasive than dilations. Gastro-esophageal reflux complaints are more often encountered after peroral endoscopic myotomy. Patient factors such as age, comorbidities, and type of achalasia must be taken into account when choosing a treatment. The preference of the patient is also of great importance and therefore shared decision making has to play a fundamental role in deciding about treatment.
