Insights
Endoscopic treatments for pediatric gastroparesis, including botulinum toxin injection and pyloric dilatation, were safe but offered only short-term relief. Frequent symptom recurrence necessitated repeated interventions in children.
Area of Science:
- Pediatric Gastroenterology
- Endoscopic Interventions
- Gastrointestinal Motility Disorders
Background:
- Gastroparesis in children presents significant management challenges.
- Endoscopic therapies are increasingly explored for pediatric gastroparesis.
Purpose of the Study:
- To compare the safety and efficacy of endoscopic intrapyloric botulinum toxin injection versus pyloric dilatation in pediatric gastroparesis.
- To evaluate recurrence rates and long-term outcomes of these endoscopic interventions.
Main Methods:
- Retrospective, multicenter study including 24 pediatric patients (median age 2.5 years) treated between 2010-2018.
- Analysis of 46 endoscopic procedures, comparing botulinum toxin injection and pyloric dilatation.
- Data collected on intervention success, recurrence, complications, and follow-up duration.
Main Results:
- Overall, 76% of interventions were successful, with no significant difference in efficacy between botulinum toxin and pyloric dilatation.
- A high recurrence rate of 57% was observed, with a median time to recurrence of 3.7 months.
- No complications were reported, indicating a favorable safety profile for both methods.
Conclusions:
- Endoscopic management of pediatric gastroparesis using balloon dilatation or botulinum toxin is safe.
- These endoscopic interventions demonstrate partial short-term efficacy, but frequent symptom recurrence is common.
- Repetition of interventions is often required due to high recurrence rates in children with gastroparesis.
Objectives:
The objective of this study was to assess the tolerance and efficacy of endoscopic intrapyloric botulinum toxin injection compared with pyloric dilatation in children with gastroparesis.
Methods:
This was a retrospective descriptive multicentre study that included pediatric patients treated between 2010 and 2018 at 4 tertiary hospitals.
Results:
Data were collected for 24 patients. The median age at diagnosis was 2.5 years (range 0.5-4.7). A total of 46 endoscopic procedures were performed. The endoscopic procedure was multiple in 63% of patients. Among the interventions, 76% were successful and 15% were unsuccessful. The recurrence rate was 57% and the median time to recurrence was 3.7 months (0.1-73). The efficacy did not differ significantly between the 2 methods at the first intervention and as a second-line treatment. The recurrence rate also did not differ significantly between the 2 methods. No complications were reported. The median follow-up was 19.8 months (1.7-61.7).
Conclusions:
In this retrospective multicentre study, endoscopic management of gastroparesis by balloon dilatation or botulinum toxin was safe in children and seemed to be partially efficient within the first months. Symptoms recurred frequently and required repetition of the interventions.
