The objective of this study was to correlate the fluoroscopy time with radiologic outcome in the pneumoreduction of intussusception in children.From September 1995 to December 1997, a prospective analysis of 181 cases of pediatric intussusception with pneumoreduction without sedation was done. A receiver operating characteristic curve of fluoroscopy time was drawn for correlation with radiologic outcome.The overall success and failure rates of pneumoreduction were 84% and 16%, respectively. Three patients (1.6%) experienced colon perforation. The mean fluoroscopy time was 2.8 +/- 1.7 minutes in successful procedure and 4.9 +/- 2.8 minutes in failed procedures (P < 0.001). Analysis of the receiver operating characteristic curve of fluoroscopy time indicates that 4 minutes fluoroscopy time was a good critical point in differentiating successful and failed cases. In those 18 patients who had successful reduction with fluoroscopy times of more than 4 minutes, 4 patients had clinical symptoms for more than 1 day and 14 patients less than 1 day. One of those 4 patients required operation 1 day later because of peritonitis caused by necrosis of terminal ileum. Two patients had high fever in the next 2 days and recovered after antibiotic treatment.Pneumoreduction is a good method in treatment of intussusception with high successful rate. Four minutes is the critical point of procedure. Reduction with greater than 4 minutes in those patients having illness more than 1 day might not benefit and have more complications.
