The majority of patients who undergo a laparoscopic fundoplication for gastroesophageal reflux disease (GERD) have a structural (hiatal hernia, shortened lower esophageal sphincter [LES]) or functional (weak LES) defect of the gastroesophageal junction (GEJ).
Numerous studies demonstrate that POEM produces comparable, if not superior, results compared to standard laparoscopic Heller myotomy (LHM), as determined by LES pressure, dysphagia frequency, Eckardt score, hospital length of stay, therapy durability, and incidence of GERD.
Gastro-esophageal reflux disease (GERD) may occur post-achalasia intervention due to disruption of the LES and therefore requires diligent follow-up, especially in children treated with POEM.
There was a prevalence of acid reflux at both sphincters (p<0.0001); liquid reflux was prevalent at the LES (p=0.003) and mixed reflux at the UES (p=0.0001).
