One of the main concerns related to peroral endoscopic myotomy (POEM) is postoperative gastroesophageal reflux (GER). The two penetrating vessels (TPVs) that are found at the boundary between the circular and oblique muscles in the posterior cardia wall have been suggested to be a good indicator of the optimal distal extent of POEM. However, the effect of performing myotomy using the TPVs as an anatomical reference on the frequency of post‐POEM GER has not been studied.
