Abdominal pain: general imaging strategies

Area of Science:

• Pediatric Surgery
• Diagnostic Imaging in Children

Background:

• Acute abdominal pain is a frequent surgical admission reason in pediatric hospitals.
• Appendicitis and non-specific abdominal pain are common causes, but other conditions can mimic appendicitis in children.
• Some pediatric abdominal pain causes are rare in adult practice.

Purpose of the Study:

• To review diagnostic approaches for acute abdominal pain in children.
• To compare the efficacy of different imaging modalities.
• To emphasize radiation protection in pediatric diagnostic imaging.

Main Methods:

• Review of current diagnostic practices for pediatric acute abdominal pain.
• Comparison of plain abdominal radiography, ultrasonography (US), and computed tomography (CT) in diagnosing pediatric abdominal pain.
• Emphasis on clinical presentation, including associated symptoms like vomiting.

Main Results:

• Plain abdominal radiographs are frequently used initially but are less informative than US without vomiting.
• Ultrasonography (US) is more effective than plain radiography in identifying the cause of abdominal pain in children.
• Computed tomography (CT) is widely used in adults but should be minimized in children due to radiation concerns.

Conclusions:

• Diagnostic imaging choices for pediatric acute abdominal pain should prioritize non-invasive and low-radiation methods like US.
• Clinical context, particularly the presence of vomiting, influences the utility of imaging modalities.
• Minimizing radiation exposure from CT scans is crucial for pediatric patients.
