Recent Trends in the Management of Achalasia

Radical treatment for achalasia is currently unavailable. At present, most palliative procedures are designed improve the passage of food through the gastroesophageal junction and thereby alleviate symptoms. Drug therapy is of limited, transient effectiveness. Pneumatic dilation (PD) is considered superior to endoscopic botulinum toxin injection (EBTI). The mainstay of surgical treatment for achalasia is laparoscopic Heller myotomy (LHM) with fundoplication, currently considered superior to PD. Per oral endoscopic myotomy (POEM), a "state-of-the-art" procedure for minimally invasive surgery, holds great promise for the future management of achalasia. Definitive conclusions regarding the benefits and risks of currently available treatments for achalasia must await the accumulation of evidence from well-designed clinical trials.
