ARTICLE HIGHLIGHTS
Research background
For recurrent achalasia after initial peroral endoscopic myotomy (POEM) failure, repeat POEM (Re-POEM) has been reported as a treatment option.
Research motivation
Interlayer adhesions caused by previous POEM procedures are common, which could impede the establishment of a submucosal tunnel and even lead to aborted Re-POEM procedures.
Research objectives
This study aimed to evaluate the efficacy and safety of Re-POEM with simultaneous submucosal and muscle dissection (Re-POEM-SSMD) as a salvage therapy for recurrent achalasia with severe esophageal interlayer adhesions after prior failed POEM procedures.
Research methods
Patients diagnosed with recurrent achalasia who underwent Re-POEM or Re-POEM-SSMD in our center were retrospectively analyzed in terms of clinical efficacy, incidence of procedure-related adverse events and reflux complications.
Research results
Clinical success (Eckardt score ≤ 3) was achieved in 8 (88.9%) patients after Re-POEM and 6 (85.7%) patients after Re-POEM-SSMD (P = 0.849). No severe adverse events were recorded in both groups.
Research conclusions
Re-POEM-SSMD could serve as a safe and effective salvage therapy for recurrent achalasia with severe interlayer adhesions.
Research perspectives
Further studies in large-scale patient population and prospective studies are required to verify the efficacy and safety of Re-POEM-SSMD in the management of patients after failed POEM. Further evaluation of the validity of Re-POEM-SSMD in reducing reflux is also awaited.
