PURPOSE: To identify age risk factors of early recurrent intussusception after pneumatic enema reduction. Management opinions are proposed. METHODS: Two thousand two hundred and ninety-five intussusception patients' medical records from January 2009 to December 2011 were retrospectively reviewed and analyzed. RESULTS: Of the 2295 patients, the intussusception of 1917 of them was initially reduced by pneumatic enema, with 127 cases recurring within 72 h. The early recurrence rate is 6.62%. The early recurrence rate of patients younger than 1 year old is 2.1% (22/1032), while the rate for those older than 1 year is 11.9% (105/885). The difference is significant (P = 0.0001). There were no significant differences between age groups older than 1 year. One hundred and seventeen cases of recurrence happened within 48 h, which accounted for 92.1% of all early recurrence. Recurrence patients were treated again with pneumatic enema, with a successful reduction in 93.7%. They were followed up for 2-4 years; the long-term recurrent rate was 11.8% (14/119). No patient had poor prognosis because of delayed treatment. CONCLUSION: Intussusception patients older than 1 year tend to have greater early recurrence rate after pneumatic enema reduction; 92.1% of the early recurrent cases happened in 48 h. There is no need to hospitalize patients after pneumatic enema reduction. A repeat pneumatic enema is a good choice before surgical approach.
