Fig. 8. Gastric peroral endoscopic myotomy for gastroparesis. (A) The distal antrum and pylorus were observed. (B) A submucosal bleb and mucosal opening were created after submucosal injection 2-3 cm proximal to the pylorus. (C) Submucosal tunneling was started from the mucosal opening and continued toward the pyloric ring. (D) A complete myotomy was performed from the distal antrum to the pyloric ring. (E) After myotomy, the pyloric opening was significantly larger. (F) The mucosal opening was closed with hemoclips.
