The suggested technique for ultrasound-assisted reduction (see the video below) includes the following steps:

  • Position the patient as previously described (see Patient Preparation)
  • Choose the high-frequency linear probe in two-dimensional mode; color Doppler may be applied if a distinction between strangulation and incarceration has not yet been established
  • Identify the point of maximal aperture of the inguinal canal or fascial defect
  • Hold the tissue perpendicular to the plane of maximal aperture, and guide it through
  • Compress the tissue from a distal point while guiding the proximal end through the aperture
