Peroral Endoscopic Myotomy (POEM): Feasible as Reoperation Following Heller Myotomy

POEM is being increasingly used for primary treatment of achalasia.  This study evaluated POEM use for retreatment of 5 achalasia patients after prior laparoscopic esophageal myotomy and compared their results to 3 patients who underwent redo laparoscopic surgery.  Both groups had similar low complication rates and improved symptoms at intermediate-term follow-up.  The authors conclude that POEM is feasible for reoperative surgery for achalasia.
