Insights
Delayed gastric emptying may contribute to gastroesophageal reflux (GER) in children. This study found prolonged gastric emptying times in infants and children with more severe GER, suggesting a potential pathogenetic role.
Area of Science:
- Pediatric Gastroenterology
- Nuclear Medicine
- Digestive Physiology
Background:
- Gastroesophageal reflux (GER) is common in infants and children.
- The interplay between gastric emptying and GER requires further investigation.
- Understanding these relationships can inform diagnostic and therapeutic strategies.
Purpose of the Study:
- To evaluate the relationship between gastric emptying and GER in pediatric patients.
- To determine if delayed gastric emptying is associated with GER disease.
- To explore age-related differences in this association.
Main Methods:
- 108 pediatric patients (3 months-5 years) with suspected GER disease underwent scintigraphy.
- Gastric emptying was assessed using Tc-99m sulfur colloid, with half emptying time (T1/2) measured.
- GER episodes were detected and graded based on scintigraphic findings.
Main Results:
- 37% of patients exhibited GER on scintigraphy.
- No significant difference in gastric emptying time was found between GER-positive and GER-negative groups overall.
- However, patients with grade 2 GER showed significantly prolonged gastric emptying times compared to controls.
Conclusions:
- Delayed gastric emptying is a significant factor in the pathogenesis of GER in infants and children.
- The severity of GER correlates with the degree of gastric emptying delay.
- These findings highlight the importance of assessing gastric emptying in pediatric GER evaluation.
Purpose:
The aim of our study was to evaluate the relationship between gastric emptying and gastroesophageal reflux (GER) in infants and children.
Methods And Materials:
One hundred eight patients (pts) between 3 months and 5 years of age (77 boys, 31 girls) with clinical suspicion of GER disease were included in the study. Patients were divided into 2 groups according to the age range: group A, 0-2 years (57 pts), and group B, 2-5 (51 pts) years. Each group was divided into 2 subgroups according to the scintigraphic study as GER-positive and -negative. Cow's milk with Tc-99m sulfur colloid as radiotracer was used. Gastric emptying was expressed as the half emptying time (T1/2). The detection of activity in the esophagus at any time during scintigraphy was considered an indicator of GER episodes. Reflux episodes were graded as grade 1 if activity was detected on one or 2 frames and grade 2 if activity was detected on more than 2 frames.
Results:
Forty of the 108 patients (37%) had GER findings on scintigraphy. The comparison of gastric emptying time between positive GER scintigraphy and negative GER scintigraphy groups was not statistically significant in any age group. No association was found between age and rate of gastric emptying time. Although the comparison of T1/2 between grade 1 patients and the GER-negative group was not statistically significant, grade 2 patients showed significant differences and had prolonged gastric emptying times. Mild statistical correlation between the number of reflux episodes and gastric emptying half time was found.
Conclusions:
As a conclusion, the relation between gastroesophageal reflux and delayed gastric emptying cannot be ignored. Our results support delayed gastric emptying to be a pathogenetic factor in gastroesophageal reflux in infants and children.
