Study Details

Study Description

Brief Summary

Esophageal outflow obstruction is characterized by failure to relax the lower esophageal sphincter (LES), resulting in impaired flow of ingested food into the stomach. The subsequent stasis of ingested food leads to symptoms of dysphagia, regurgitation, chest pain, and weight loss. The core objective of the treatment of esophageal outflow obstruction is to disrupt the LES and reduce its pressure to allow esophageal emptying. Therapeutic options include pharmacologic therapy, Botulinum toxin injection, pneumatic balloon dilation, and surgical myotomy with partial fundoplication. In addition, peroral endoscopy myotomy (POEM) has recently been introduced as a minimally invasive treatment, but there have a few studies regarding long-term outcomes. The aim of this study is to evaluate clinical outcomes of POEM for esophageal outflow obstruction.

Arms and Interventions

Arm Intervention/Treatment
Other: Peroral endoscopic myotomy (POEM)

Patients who received POEM

Other: peroral endoscopic myotomy
The procedure consists of four steps: 1) mucosal incision 10-15 cm above the esophagogastric junction to allow entry into the submucosa, 2) creation of a submucosal tunnel until the lower esophageal sphincter is reached, 3) myotomy of the circular muscle layer, and 4) closure of the mucosal entry with endoclips.

Outcome Measures

Primary Outcome Measures

  1. number of patients with Eckardt score <3 after the procedure [1 month after the procedure]

Secondary Outcome Measures

  1. adverse events which are related to the procedure [within 30 days]
