Pushing Backwards: Evaluating Effectiveness of Conservative Treatment of Intestinal Intussusception

Intestinal intussusception (II) is a common cause for acute abdomen in children, occurring in 0.33 to 0.71 per 1000 children per year. Early diagnosis and treatment are fundamental for prevention of irreversible intestinal damage. The first line of treatment is conservative, with saline reduction enema or air reduction enema. Our goal is to evaluate results with conservative treatment of II in children.

A retrospective single-center review of all patients with diagnosis of II from January 2014 to December 2019 was performed. Demographics, clinical data, treatment option, and results were assessed.

Thirty-eight cases were identified. The mean age was 26 months, and 68% were males. Most presented with abdominal pain (95%) and vomiting (66%), after an average of 30 hours. Rectal bleeding was present in 32% of patients. Abdominal ultrasound was performed in all patients for diagnosis. Conservative treatment was first option in 95% of patients, with a global effectiveness of 83% after 1 attempt. Saline reduction enema was more effective than air reduction enema (88% vs 70%), and patients with successful reduction were younger (24 vs 33 months), but neither reached statistical significance. Two patients had a subsequent II episode within 1 week after hospital discharge. Neither age, sex, symptoms and respective duration, rotavirus inoculation, intussuscepted bowel length, nor technique used was predictive of treatment failure or II relapse.

Conservative treatment in II is a safe and effective option, preventing invasive surgical procedures. Effectiveness of such treatments may be as high as 88% after 1 attempt, with rapid diet reintroduction. Same-day discharge after oral feeding toleration is safe.
