Abstract

|
|
Achalasia cardia is a rare esophageal motility disorder. Although a primary neurological disorder, the treatment modalities of achalasia are primarily endoscopic or surgical. Pneumatic dilatation (PD) or laparoscopic Heller’s myotomy (LHM) have been the mainstay of achalasia management for several decades. With the introduction of third space endoscopy, the endoscopic management of achalasia has revolutionized. Randomized studies have concluded the superiority of per-oral endoscopic myotomy (POEM) over PD. In addition, the short-term outcomes of POEM are similar to LHM. POEM is a relatively new technique and long-term data is eagerly awaited. The main concern after POEM is a high incidence of gastroesophageal reflux disease (GERD) which is found in about half of the patients undergoing this procedure. GERD is higher after POEM when compared to PD and LHM with fundoplication. The management of achalasia should be individualized and based on factors like patient characteristics (age, sex, comorbidities), subtyping on high resolution manometry, patient/doctor preference, and surgical risk of the patient.
