Questions and Answers

What is the preferred method for reduction of an intussusception in many centers?

  • Using air and barium
  • Using barium and ultrasound
  • Using water-soluble contrast medium and ultrasound
  • Using air and fluoroscopy (correct)
  • Why is barium no longer used in the majority of centers for the reduction of intussusception?

  • It leads to a more rapid reduction
  • It results in a lower radiation dose
  • It may wash gut organisms into the peritoneal cavity in the event of a perforation (correct)
  • It allows for more accurate control of intraluminal pressure
  • What is a contraindication for the pneumatic method of reduction?

  • Use of barium and ultrasound
  • Peritonitis, perforation, or shock (correct)
  • Use of water-soluble contrast medium and ultrasound
  • Use in children under 4 years of age
  • Why is the pneumatic method not recommended for children over 4 years of age?
