RESUMO

BACKGROUND: International practice regarding the method used to nonoperatively reduce pediatric intussusception is variable. OBJECTIVE: To provide an overview of ultrasound-guided pneumatic intussusception reduction and assess its safety and effectiveness. MATERIALS AND METHODS: A single-center prospective study was conducted in a tertiary referral pediatric hospital during the 15-year period between January 2008 and February 2023. All patients with ileocolic intussusception underwent abdominal sonographic examination for diagnosis. An ultrasound-guided pneumatic reduction of intussusception was then attempted. Children who were hemodynamically unstable, with signs of peritonitis or bowel perforation and those with sonographically detected pathologic lead points were excluded. RESULTS: A total of 131 children (age range 2 months to 6 years) were enrolled in this study. Pneumatic intussusception reduction was successful in 128 patients (overall success rate 97.7%). In 117 patients, the intussusception was reduced on the first attempt and in the remaining on the second. In three cases, after three consecutive attempts, the intussusception was only partially reduced. As subsequently surgically proven, two of them were idiopathic and the third was secondary to an ileal polyp. No bowel perforation occurred during the reduction attempts. There was recurrence of intussusception in three patients within 24 h after initial reduction which were again reduced by the same method. CONCLUSION: Ultrasound-guided pneumatic intussusception reduction is a well-tolerated, simple, safe and effective technique with a high success rate, no complications and no ionizing radiation exposure. It may be adopted as the first-line nonsurgical treatment of pediatric intussusception.
