Purpose: The aims of this study were to evaluate the need for surgical intervention for patients with recurrent ileocolic intussusception (RICI), especially for multiple recurrences, and to investigate whether early and late recurrence patterns were associated with surgery.
Methods: Patients with ileocolic intussusception (ICI) during the years 2007-2019 were included. Demographic data, recurrences, and outcomes were analyzed. Early RICI was defined as recurrence within 48 h.
Results: Overall, 604 episodes of ICI were confirmed in 491 patients. The recurrence rate was 13.8%, with 113 episodes in 68 patients. There were no statistically significant differences in age, reduction success rate, operation, or pathological lead points (PLPs) between the recurrence and non-recurrence groups. There was no significant association between the number of recurrences and the presence of a PLP or between the number of recurrences and whether the recurrences were early or late. The presence of PLPs was not significantly associated with age or recurrence, but the reduction success rate was significantly lower (P < 0.001).
Conclusions: Each recurrence should be managed as a first episode, regardless of early or late recurrence. Operative reduction should be considered when nonoperative reduction fails, a PLP is suspected, or there are signs of peritonitis.
Type of study: Treatment Study.
Level of evidence: Level III.
