    Abstract:
    AIM: To describe patterns and risk factors of multiple recurrences to optimise management for pediatric patients with more than four episodes of intussusception. MATERIALS AND METHODS: Following IRB approval, all sonographic evaluations for intussusception in patients <18 years over a 6-year period were reviewed. Data extracted included age at onset of first intussusception, gender, presenting symptoms, symptoms upon recurrence, presence of pathological lead points, and surgical findings. RESULTS: During a 6-year period, five cases had four or more instances of recurrence after enema reduction attempts. All patients were male with an average age of 16 months. Two of the five cases resolved after the fourth enema reduction and no lead points were identified. Two other cases involved surgical reduction with intraoperative findings of Meckel's diverticulum and juvenile polyp. The final case had five recurrence episodes and six separate enema reductions. Ultimately, lymphoid hyperplasia was discovered on colonoscopy and the patient never recurred after being treated with steroids. CONCLUSION: Given the favorable reduction rate in re-recurrent cases and complete lack of perforation observed, up to four attempts at enema reduction is recommended before considering an alternative strategy. If recurrence continues past the fourth reduction attempt, computed tomography (CT) is recommended to identify a lead point. If CT remains inconclusive, then consider exploratory laparotomy.
