Intestinal ultrasonography in pediatric population.

Area of Science:

• Pediatric Gastroenterology
• Diagnostic Imaging
• Medical Ultrasound

Background:

• Bowel ultrasound (US) is a low-cost, non-invasive, bedside diagnostic tool.
• It is particularly effective for evaluating neonatal and pediatric gastrointestinal (GI) diseases due to patient anatomy.
• A 3- to 5-hour fasting state can improve examination quality.

Purpose of the Study:

• To provide an overview of findings, signs, and applications of US in major pediatric GI diseases.
• To highlight the utility of US in the diagnostic workup of acute and chronic GI conditions in children.
• To detail the US assessment of GI tract structures and associated tissues.

Main Methods:

• Focus on evaluating GI wall thickness, stratification, lumen content, distensibility, compressibility, and peristalsis.
• Includes investigation of the mesentery, perivisceral tissues, and lymph nodes.
• Utilizes color Doppler flowmetry for assessing vascularization of the GI wall and mesentery.

Main Results:

• Healthy GI walls appear as sequential hyperechoic and hypoechoic layers on US.
• US allows for qualitative evaluation of GI wall and mesentery vascularization.
• The technique is reproducible and yields high diagnostic information for various GI diseases.

Conclusions:

• Bowel US is a high-yield, reproducible, and non-invasive method for diagnosing pediatric GI diseases.
• It offers significant advantages in evaluating young patients due to their body size and reduced abdominal fat.
• This article serves as a guide to US findings in common pediatric GI conditions.
