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.

Gastric Emptying01:16

Gastric Emptying

Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...
Gastroesophageal Reflux Disease01:25

Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...

Gastroesophageal Reflux Disease I: Meaning and Pathophysiology

Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

Gastroesophageal Reflux Disease II: Clinical Features and Management

Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
Hiatal Hernia01:25

Hiatal Hernia

A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...
