英文摘要 | Hirschsprung disease is common in children and is generally diagnosed by contrast enema. The objective of our study was to determine whether radiation time can be decreased and an adequate diagnostic sensitivity and specificity can be obtained using a simplified contrast enema as compared to using a conventional contrast enema. Moreover, the study describes the diagnostic value of a 24-hour-delayed radiograph. We reviewed the data for 198 consecutive children who had received a contrast enema between January 2009 and December 2010 in our hospital for suspicion of Hirschsprung disease. Of the 198 children, 18 were excluded because 24-hour-delayed abdominal radiographs were not available, they had previously undergone a gastrointestinal tract surgery, or they had previously received a contrast enema. We reviewed the radiographs taken during contrast enema examination of the remaining 180 children. The time taken for the procedure was recorded for 15 patients. Rectal suction biopsy was performed in 45 patients. The results obtained in all cases were analyzed. The results of conventional and simplified contrast enema examinations showed markedly high correlation in all cases, except for 1 case. The sensitivity of the 24-hour-delayed radiograph ranged from 60.87% to 98.65% and its specificity ranged from 8.92% to 35.67%, depending on different diagnostic rules. The radiation time required for simplified contrast enema was approximately 33.87% of that required for conventional contrast enema. Similar diagnostic values were obtained using both simplified and conventional contrast enema examinations; however, the radiation time required for simplified contrast examination was significantly lower. The 24-hourdelayed abdominal radiograph added to the diagnostic value; however, its specificity was very low. |
