Pneumatic reduction for intussusception achieved higher success rates (86%) than barium reduction (67%), with similar complication rates. Radiation doses were comparable between methods, with a median effective dose of 55 microSv.

Area of Science:

  • Pediatric Radiology
  • Gastroenterology

Background:

  • Intussusception is a common surgical emergency in infants and children.
  • Radiological reduction is the preferred treatment, with pneumatic (air) and hydrostatic (barium) methods commonly used.
  • Radiation dose during these procedures is a concern.

Purpose of the Study:

  • To compare the efficacy and safety of pneumatic versus hydrostatic reduction of intussusception.
  • To assess the radiation effective dose to patients during these procedures.
  • To evaluate the impact of a change in reduction medium from barium to air.

Main Methods:

  • Retrospective analysis of 58 intussusception reductions in 55 patients.
  • Comparison of reduction success rates and complication rates between air and barium reduction.

  • Measurement of effective radiation dose using a dose-area product meter.

    • Main Results:

    • Pneumatic reduction (air) had a higher success rate (86%) compared to hydrostatic reduction (barium) (67%).
    • Complication rates were similar for both methods.
    • Median effective patient dose was 55 microSv, with a 75th percentile dose of 75 microSv.
    • No significant difference in radiation dose was found between air and barium reduction.

    Conclusions:

    • Pneumatic reduction offers advantages in success rates for intussusception compared to hydrostatic reduction.
    • Radiation doses are comparable between air and barium reduction methods.
    • It is feasible to maintain patient effective dose at or below 75 microSv during fluoroscopic-guided reduction.
