Keywords
Antireflux Mucosectomy, GERD
Brief summary
This is a phase II clinical study to investigate the safety and efficacy of endoscopic antireflux mucosectomy (ARMS) for treatment of GERD.
Detailed description
The objective of the study is to establish the clinical efficacy and safety of ARMS for treatment of GERD.
Interventions
ARMS aimed at resection of mucosa at gastric cardia to induce fibrosis and tighten the gastroesophageal junction and reduce acid reflux
