Insights
Delayed gastric emptying (DGE) in children is linked to abnormal antroduodenal manometry (ADM) findings, including reduced antral contractions and altered migrating motor complex patterns.
Area of Science:
- Pediatric Gastroenterology
- Gastrointestinal Motility Disorders
- Diagnostic Endoscopy
Background:
- Pediatric gastroparesis diagnosis often involves antroduodenal manometry (ADM) and gastric emptying scintigraphy (GES).
- Correlation between delayed gastric emptying (DGE) and ADM findings in children remains unclear.
- This study investigates ADM parameter differences in pediatric patients with normal versus abnormal GES.
Purpose of the Study:
- To determine if antroduodenal manometry (ADM) parameters differ between pediatric patients with delayed gastric emptying (DGE) and normal gastric emptying (NGE).
- To identify specific manometric abnormalities associated with DGE in children.
Main Methods:
- Retrospective review of pediatric patients undergoing ADM and GES (2011-2020).
- Comparison of manometry parameters (motility index, contraction number, phase III migrating motor complex [MMC]) between DGE (n=32) and NGE (n=32) groups.
- Age, sex, BMI, and weight-matched patient cohorts were analyzed.
Main Results:
- Children with DGE exhibited lower post-prandial antral motility index and contraction numbers compared to NGE.
- Lower gastric emptying at 4 hours was observed in patients with retrograde phase III MMC or absent antral component in fasting phase III MMC.
- Post-prandial antral hypomotility was significantly more frequent in the DGE group.
Conclusions:
- Antroduodenal manometry (ADM) findings are distinct between pediatric patients with delayed gastric emptying (DGE) and normal gastric emptying (NGE).
- Children with DGE are more prone to abnormal fasting phase III patterns and reduced post-prandial antral activity on ADM.
Background/Aims:
Pediatric patients with suspected gastroparesis often undergo antroduodenal manometry (ADM) and gastric emptying scintigraphy (GES) for diagnostic purposes. However, it is unknown if delayed gastric emptying (DGE) correlates with manometric findings. This study evaluates whether ADM parameters differ between normal and abnormal GES in pediatric patients.
Methods:
Data from pediatric patients undergoing ADM and GES at Nationwide Children's Hospital from 2011-2020 were retrospectively reviewed. Manometry parameters including motility index (Ln [sum of amplitudes × number of contractions + 1]), number of antral contractions, and direction of the phase III migrating motor complex (MMC) were compared to GES results from age-matched patients with DGE (n = 32) and normal gastric emptying (NGE) (n = 32) of similar sex, body mass index, and weight.
Results:
Children with DGE had a lower post-prandial antral motility index and antral contraction number than those with NGE (9.4 vs 11.2, P = 0.005; 21.8 vs 49.6, P < 0.001). The gastric emptying percentage at 4 hours was lower in patients with retrograde phase III (59.2% vs 83.9%, P = 0.022) and in those without an antral component in the fasting phase III of the migrating motor complex (70.3% vs 86.5%, P = 0.003). Post-prandial antral hypomotility occurred more frequently in the DGE group than in the NGE group (41% vs 9%, P = 0.008).
Conclusions:
ADM findings differ between children with DGE and NGE. Children with DGE are more likely to have abnormal fasting phase III patterns and decreased post-prandial antral activity during ADM testing.
