Peroral endoscopic myotomy in pediatric triple A syndrome: report of three cases.

Triple A syndrome (Allgrove syndrome) is a rare inherited disorder characterized by adrenal insufficiency, alacrima, and achalasia. Despite POEM's established role in achalasia management, its effectiveness in Triple A syndrome remains largely undefined, as fewer than 10 cases have been reported. We present three genetically confirmed pediatric Triple A patients (two males, one female; 11-16 years) with long-standing achalasia, all with Eckardt scores of 12 on admission and successfully treated with POEM after failing conventional therapies.
