3 clinical questions

(1) Does previous interventions affect feasibility and safety of POEM?

A. Severe fibrosis and anatomical change due to previous interventions could complicate the procedure. However, it is still feasible. (Onimaru M, Inoue H. J Am Coll Surg 2013;217:598-605, Vigneswaran Y. J Gastrointest Surg 2014)

(2) How long do we have to cut the muscle?

A. Still inconclusive. If the abnormal contraction of the esophageal body was only a secondary change, myotomy should not be too long in order to avoid dysfunction of the esophageal body.

(3) Which is better? Anterior? Posterior?

A. Longer observation with more cases is awaited. Multicenter RCT is now ongoing.
