Core Tip	Management of achalasia with epiphrenic diverticulum is evolving. A one-size-fits-all septotomy is no longer justified. Intra-procedural endoscopic phenotyping allows for a selective approach: Division of a functionally obstructive muscular septum when present and standard myotomy alone when absent. This precision strategy, supported by recent meta-analytic data showing high treatment success for per-oral endoscopic myotomy in epiphrenic diverticula, achieves comparable outcomes to universal septotomy while minimizing overtreatment and its associated risks.
