Abstract
Background and aims
Achalasia cardia is rare in children and optimum endoscopic management options are not well known. Peroral endoscopic myotomy (POEM) is a novel treatment modality for achalasia with excellent results in adult patients. The long-term outcomes of POEM are not well known in children. In this study, we aim to evaluate the outcome of POEM in children with idiopathic achalasia.
Methods
We analyzed the data of children (≤ 18 years) diagnosed with achalasia from September 2013 to January 2018. Technical success, clinical success, and adverse events were assessed. Post-POEM, gastroesophageal reflux (GER) was assessed with 24-h pH-impedance study and esophagogastroduodenoscopy.
Results
A total of 44 children (boys—23, girls—21) with mean age of 14.5 ± 3.41 years (4–18) were diagnosed with achalasia during the study period. Of these, 43 children underwent POEM. The subtypes of achalasia according to Chicago classification were type I—11, type II—29, type III—2, and unclassified—2. Eighteen children (40.9%) had history of prior treatment. POEM was successfully performed in 43 children (technical success—97.72%). Intra-operative adverse events occurred in 11 (25.6%) children including retroperitoneal CO2 (7), capnoperitoneum (3), and mucosal injury (1). Clinical success at 1, 2, 3, and 4 years’ follow-up was 92.8%, 94.4%, 92.3%, and 83.3%, respectively. Erosive esophagitis was detected in 55% (11/20) children. On 24-h pH study, GER was detected in 53.8% (7/13) children.
Conclusion
POEM is a safe, effective, and durable treatment for achalasia in children. However, GER is a potential concern and should be evaluated in prospective studies before adopting POEM for the management of achalasia in children.
