Background Increase in GERD could be associated with posterior POEM due to the cutting of sling fibers (SF). Recently, it has been described presence of two penetrating vessels (TPV) as a guide for myotomy.

Endoscopic findings Mucosotomy with conventional tunneling. First penetrating vessel usually located overstepping Cardia at 5-6 o´clock, and the second at 3-4 o´clock two cm distally to the first one. SF identified towards the left edge of TPV. Gastric Myotomy performed moving forward to the right side of the TPV.

Conclusions TPV could be benchmarks to the tunnel ends and a guide for selective myotomy preserving SF in posterior POEM.
