This study aimed clarify the feasibility and short-term clinical efficacy of POEM compared laparoscopic Heller (LHM). Methods. Treatment outcomes were prospectively recorded between procedures in nonrandomized fashion. Reduction rate (RR) timed barium esophagogram (TBE) was calculated at 1, 2 5 min after ingestion as: RR = 1− postoperative...
