Idiopathic intussusception in infancy and childhood.
OBJECTIVE
Idiopathic intussusception is an important cause of abdominal pain, bleeding per rectum and intestinal obstruction in infancy and childhood. This aim of this study was to undertake a retrospective review of all children who presented with idiopathic intussusception over a 17-year period.


METHODS
The medical records of children who presented with idiopathic intussusception from January 1984 through December 2000 at King Fahad National Guard Hospital, Riyadh, Kingdom of Saudi Arabia were reviewed. The data obtained included age, sex, clinical presentation, diagnostic investigations, mode of treatment, length of hospital stay and results.


RESULTS
Thirty-three children (21 male, 12 female) presented with 37 episodes of intussusception. Their mean age was 8.4 months (range 5 hours to 36 months). The clinical features included rectal bleeding (81%), vomiting (78%), abdominal colic/pain (65%) and abdominal mass (62%). All cases were ileocolic intussusception with no leading point. Barium enema was attempted in 36 cases with success in 20 (56%). Laparotomy was required in 16 cases, manual reduction being successful in 11 (30%) and 6 (16%) had bowel resection. At surgery, after attempted barium reduction, 9 (56%) cases had the intussusception already reduced to the cecum. Seventy percent of the cases presented within 24 hours of onset of symptoms. The 4 recurrences in 3 children had successful enema reduction. There was no mortality but 3 operative cases required late surgery for adhesive intestinal obstruction including one requiring bowel resection.


CONCLUSIONS
Idiopathic intussusception commonly presents as an ileo-colic type but is uncommon in our institution. The clinical features are classical, rectal bleeding being the most common. The majority presented within 24 hours of onset of symptoms and barium enema reduction was successful in 20 out of 36 cases in which it was attempted. Since most intussusceptions were already in the cecum at surgery after failed enema reduction, a repeat or delayed enema reduction could be considered in stable cases. Recurrent intussusception occurred in 3 non-operated cases and adhesive intestinal obstruction in 3 laparotomy cases.
