Abstract
Background
Peroral endoscopic myotomy (POEM) has shown excellent results for the treatment of achalasia in adults, but studies for children are limited. The study was aimed to analyze outcomes of peroral endoscopic myotomy (POEM) in children and compared with those in adults in a large multi-center study.
Methods
Records of consecutive patients with achalasia who underwent POEM at three tertiary centers were reviewed. A total of 130 children were included in this study. The primary outcomes of perioperative outcomes and clinical follow-up data were analyzed.
Results
One child (0.8%) experienced technical failure. Five children (3.8%) had major adverse events, including one with pneumothorax requiring drainage, two with delayed mucosa barrier failure, one with readmission, and one with vital-sign instability. Both post-POEM Eckardt score and median LES pressure were significantly lower than their pre-POEM reference values in children (0.7 vs 7.4; 7.0 vs 27.1 mmHg; both P < 0.001). During a median follow-up time of 40 months, clinical reflux rate was 27.0% and clinical failure rates at 1, 3, and 5 years were 1.8%, 3.5%, and 4.4% for children. The technical failure, major adverse events, and postoperative clinical reflux were comparable between children and adults (all P > 0.05). Kaplan–Meier analysis showed that the risk of clinical failure was lower in children than adults (log-rank test, hazard ratio = 0.37, 95% confidence interval 0.15–0.91, P = 0.023).
Conclusions
POEM can be safely performed in children with achalasia, and produce a better clinical response during long-term follow-up compared with that in adults.
