Evaluating pediatric intussusception using 24-hour ultrasound

Area of Science:

• Pediatric Radiology
• Medical Imaging
• Gastroenterology

Background:

• Ultrasound is the preferred imaging for pediatric intussusception.
• Limited nighttime ultrasound access necessitates alternative imaging methods.
• Radiographic imaging use varies between day and night for intussusception evaluation.

Purpose of the Study:

• To characterize day- and nighttime radiographic imaging use for pediatric intussusception.
• To compare clinical characteristics, imaging modalities, costs, and diagnoses.
• To assess the impact of imaging timing on treatment outcomes and radiation exposure.

Main Methods:

• Retrospective chart review of pediatric patients with suspected intussusception (January-December 2010).
• Stratification into day and night groups based on imaging study timing.
• Comparison of imaging types, enema success rates, and radiation doses.

Main Results:

• Nighttime imaging predominantly used plain abdominal X-rays and CT, unlike daytime ultrasounds.
• Positive enema reduction rates were significantly higher during the day (97.5%) versus night (52.2%).
• Mean radiation dose was substantially lower during daytime imaging (0.63 mSv) compared to nighttime (2.06 mSv).

Conclusions:

• Nighttime radiographic imaging for intussusception is associated with increased radiation exposure and lower enema success.
• Implementing 24-hour ultrasound availability can mitigate radiation risks and reduce unnecessary interventions.
• Optimizing imaging protocols is crucial for effective and safe pediatric intussusception management.
