Insights
Per-oral endoscopic myotomy (POEM) is a safe and effective treatment for pediatric achalasia, resolving dysphagia in all patients. This study supports POEM as a viable option for children with this esophageal motility disorder.
Area of Science:
- Gastroenterology
- Pediatric Surgery
- Endoscopic Procedures
Background:
- Achalasia is a rare primary esophageal motor disorder in children.
- Laparoscopic Heller myotomy (LHM) is the standard surgical treatment.
- Per-oral endoscopic myotomy (POEM) is an emerging alternative in adults.
Purpose of the Study:
- To evaluate the safety and effectiveness of POEM in pediatric achalasia patients.
- To report outcomes from a Chilean medical center cohort.
Main Methods:
- Retrospective analysis of prospectively collected data.
- Inclusion of pediatric patients undergoing POEM for achalasia.
- Clinical follow-up using Eckardt score, high-resolution esophageal manometry (HREM), and endoscopy.
Main Results:
- Five pediatric patients (mean age 11) underwent POEM (2017-2019).
- One patient had prior LHM; no morbidity or mortality observed.
- All patients achieved dysphagia resolution with a significant reduction in Eckardt score (10 to 1).
Conclusions:
- POEM demonstrates safety and effectiveness in pediatric achalasia.
- Further research with larger cohorts and longer follow-up is warranted.
- POEM shows promise as a treatment for pediatric achalasia.
Background:
Achalasia is the most common primary motor disorder of the esophagus, but its incidence in pediatric patients is low. Laparoscopic Heller myotomy (LHM) is the current surgical standard of care treatment. Per-oral endoscopic myotomy (POEM) has emerged as a safe and effective therapeutic alternative in adult patients. We herein report the outcomes of a cohort of pediatric patients with achalasia treated by POEM at a Chilean medical center.
Methods:
This is a retrospective analysis of prospectively collected data on children who underwent POEM for esophageal achalasia. Clinical follow-up was evaluated by recording the Eckardt score, a high-resolution esophageal manometry (HREM) three months after the procedure, and an annual upper gastrointestinal endoscopy.
Results:
Five patients with esophageal achalasia confirmed by HREM and with a mean age of 11 (5 to 15) years underwent POEM between 2017 and 2019. One patient had a previous LHM. No morbidity or mortality was observed. All patients resolved their dysphagia and no patient required further interventions. Mean Eckardt score reduced from 10 points preoperatively to 1 point postoperatively. Two patients currently have mild esophagitis (confirmed by endoscopy).
Conclusion:
Our results support the previously reported safety and effectiveness of POEM. Longer follow-up and larger cohorts will be important to confirm its role in the treatment of children with esophageal achalasia.
Type Of Study:
Treatment study.
Level Of Evidence:
Level IV.
