Recurrence of intussusception in childhood.
Intussusception is the most common cause of intestinal obstruction between 3 months and 6 years of age. Recurrence after reduction of intussusception in childhood is not rare. To assess the incidence and determinants of recurrence of intussusception in childhood, we conducted a prospective observation in an emergency service of a large referral center during a four-year period. We encountered 89 cases with intussusception of whom nine cases (10.1%) had episodes of recurrent intussusception. Five patients had a single recurrence, three had double recurrence and one had triple recurrence. Age of first intussusception, sex, or concurrent adenovirus infection was not related to the recurrence. None of the 27 patients who needed operative reduction had recurrence, while 9 of 62 patients who were reduced successfully by barium enema developed recurrence (P = 0.05). Compared with the first episode, significantly less vomiting, rectal bleeding and shorter duration of abdominal pain or irritable crying were noted during recurrent episodes. All the recurrent episodes were reduced successfully by barium enema. We conclude that recurrent intussusception in childhood tends to be diagnosed earlier than previous episodes and treated successfully by hydrostatic reduction without complication. Surgical reduction of recurrent intussusception may be reserved for cases of failure of hydrostatic reduction, positive peritoneal sign or existence of pathological lead point because of favorable response to barium reduction. Recurrent intussusception seldom occurs in patients who underwent surgical reduction.
