Abstract
Endoscopic antireflux therapy is a novel endoscopic treatment for refractory gastroesophageal reflux disease. We developed antireflux myoplasty (AR‐MP), a modified version of antireflux mucoplasty (ARM‐P), in which exposed bilateral sling fibers are sutured directly via endoscopic hand‐suturing. AR‐MP was performed on a 60‐year‐old man, resulting in symptomatic improvement and allowing discontinuation of acid‐suppressive medication 3 months after the procedure. One month postoperatively, endoscopy showed an improvement in the Hill classification from grade 3 to grade 1. Before AR‐MP, endoscopic pressure study integrated system findings showed a maximum intragastric pressure value of 13.7 mmHg, indicating a flat pattern. After AR‐MP, maximum intragastric pressure exceeded 20 mmHg, and the pattern shifted to uphill. AR‐MP is an innovative endoscopic technique that reconstructs the native antireflux mechanism by suturing the sling fibers and reforming the gastroesophageal flap valve. This innovative endoscopic procedure, like ARM‐P, provides immediate symptom relief and represents a breakthrough in the endoscopic treatment of gastroesophageal reflux disease.
