Abstract
BACKGROUND: There is no consensus as to when surgical intervention should be considered for recurrent ileocolic intussusceptions in a stable patient after previous successful air contrast enema. OBJECTIVE: To review the patterns of ileocolic intussusceptions, air contrast enema success rates, and pathologic lead point rates in patients with and without recurrence to evaluate whether treatment outcomes depend on the number and timing between episodes. MATERIALS AND METHODS: We retrospectively reviewed 683 children with air contrast enema performed for ileocolic intussusception between January 2000 and May 2018. Recurrent intussusceptions were separated into mutually exclusive categories: short-term only (≤7 days between episodes) and long-term (>7 days between episodes) intussusceptions. Long-term recurrences included both long-term only and long- and short-term intussusceptions. RESULTS: Of the 683 patients, 606 (89%) had at least 1 successful air contrast enema. Of the 606, 115 (19%) had recurrent intussusceptions after successful reduction. The air contrast enema success rate for a single intussusception was 86% (491/568) and for recurrent intussusceptions was 96% (110/115) (P=0.004). Single and recurrent intussusceptions had similar pathologic lead point rates (3.5% vs. 4.3%; P=0.593). Short-term and long-term recurrences did not differ in air contrast enema success rates (96% vs. 95%). Long-term recurrences had higher pathologic lead point rate compared to short-term only (13% vs. 0%; P=0.003). Of short-term recurrences, 99% (76/77) were ≤5 intussusceptions; 92% had successful air contrast enema without surgery. CONCLUSION: The majority of recurrent intussusceptions were successfully treated by air contrast enema. Short-term recurrences have lower pathologic lead point rates, suggesting that a higher surgical threshold may be plausible relative to long-term recurrences. In the appropriate clinical context, repeat air contrast enemas are a safe option for short-term recurrences, which can be attempted at least five times, potentially precluding the need for surgical intervention.
