Fig. 2. Endoscopic findings and high-resolution impedance manometry (HRIM) in a representative case before and 3 months after antireflux mucosal ablation (ARMA). (A) Wide cardia opening (gastroesophageal flap valve grade III) before ARMA. (B) Tightened cardia (gastroesophageal flap valve grade I) after ARMA. (C) Absent contractility (100% failed contraction) on HRIM before ARMA. (D) Improved esophageal motility (10% intact, 40% weak, and 50% failed contraction) after ARMA.
