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.

Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

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...

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists01:28

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists

Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists01:23

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Gastric Motility01:16

Gastric Motility

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.

Upon food entry, the stomach initiates...

Intestinal Phase of Digestion01:29

Intestinal Phase of Digestion

The intestinal phase of digestion is the third and final stage of the digestive process, occurring after the cephalic and gastric phases. It begins when chyme, a partially digested mixture of food and digestive enzymes, enters the small intestine from the stomach. This phase is crucial for nutrient absorption and involves complex hormonal and enzymatic interactions.
The arrival of the chyme in the small intestine distends the duodenum, which triggers the enterogastric reflex. This distension...
