Summary
This summary is machine-generated.

Pediatric radiologists predominantly use barium for intussusception diagnosis and treatment. Barium enemas are common even with suspected small bowel obstruction, showing a low perforation rate.

Area of Science:

  • Radiology
  • Pediatric Imaging
  • Gastrointestinal Diagnostics

Background:

  • Intussusception is a common pediatric surgical emergency.
  • Contrast enema is a primary diagnostic and therapeutic tool for intussusception.
  • Choice of contrast media and associated risks require ongoing evaluation.

Purpose of the Study:

  • To survey North American pediatric radiologists regarding contrast media selection for intussusception.
  • To assess current practices in contrast enema administration for intussusception, including cases with suspected small bowel obstruction.
  • To determine the incidence and outcomes of complications, specifically perforation, associated with barium enemas.

Main Methods:

  • A survey was conducted among pediatric radiologists across 40 children's hospitals in North America.

  • Respondents were interviewed about their preferred contrast agents for intussusception diagnosis and treatment.
  • Data on intussusception cases, including the use of barium enema and occurrences of perforation, were analyzed.

    • Main Results:

    • Barium was the overwhelmingly preferred contrast medium for intussusception management.
    • Most radiologists would perform a barium enema even with clear evidence of small bowel obstruction on plain films.
    • Out of over 14,000 intussusception cases, 55 perforations occurred (approximately 1 in 250), with most being well-tolerated, but one fatality was reported.

    Conclusions:

    • Barium remains the standard contrast agent for pediatric intussusception.
    • The practice of performing barium enemas despite evidence of small bowel obstruction is prevalent.
    • While perforations are infrequent and generally well-tolerated, they represent a significant risk that warrants careful consideration.
