Insights

This study presents a novel image-guided transrectal drainage technique for pediatric deep pelvic abscesses. The method utilizes transabdominal ultrasound and the Seldinger technique for effective catheter placement, offering an improved approach.

Area of Science:

  • Pediatric surgery
  • Interventional radiology
  • Medical device technology

Background:

  • Deep pelvic abscesses in children pose treatment challenges.
  • Current transrectal drainage methods have limitations.
  • Image guidance is crucial for deep pelvic abscess management.

Purpose of the Study:

  • To describe a novel image-guided transrectal catheterization technique for pediatric deep pelvic abscesses.
  • To evaluate the feasibility and application of this technique.
  • To address limitations of existing transrectal drainage methods.

Main Methods:

  • Transabdominal ultrasound guidance for transrectal catheter advancement.
  • Use of an Amplatz dilator with coaxial metal cannula and inner trocar.
  • Pigtail catheter placement via Seldinger technique.
  • Single-institutional experience with 13 pediatric patients.

Main Results:

  • Successful transrectal catheter introduction and abscess drainage was achieved.
  • The described technique demonstrated feasibility in 13 pediatric cases.
  • This method offers an alternative to existing transrectal drainage approaches.

Conclusions:

  • The described image-guided transrectal drainage technique is effective for pediatric deep pelvic abscesses.
  • This approach offers advantages over other transrectal methods.
  • Further evaluation in a larger cohort is warranted.
