Objective: To see if the rectoanal inhibitory reflex could be visualized with a modified contrast enema, thereby increasing the diagnostic accuracy of the contrast enema and reducing the number of rectal biopsies.Materials and method: 59 boys and 42 girls (median age 12 months) with suspected Hirschsprung disease were examined with a modified contrast enema, supplemented with two injections of cold, water-soluble contrast medium, in order to induce the reflex. Two paediatric radiologists evaluated the anonymised examinations in consensus. The contrast enema findings were correlated with the results of rectal biopsy or clinical follow-up.Results: Five boys and one girl (median age 7.5 days) were diagnosed with Hirschsprung disease. The negative predictive value of the rectoanal inhibitory reflex was 100%. A contrast enema with signs of Hirschsprung disease in combination with an absent rectoanal inhibitory reflex had the specificity of 98% and sensitivity of 100% for Hirschsprung disease. Conclusion:The modified contrast enema improves the x-ray diagnosis of Hirschsprung disease. By demonstrating the rectoanal inhibitory reflex in children without Hirschsprung disease the proportion of unnecessary rectal biopsies can be reduced. 3(20)

Clinical Examinations of the Rectoanal Inhibitory Reflex Correlated with Anography Findings, Histopathological Findings, and Clinical Outcomes

“…It is tempting to consider that the RAIR could be visualized during a child's clinical examination using a modified CE [12]. The aim of this study was to evaluate the application of clinical cold fluid examination using only saline to observe the existence of the RAIR.…”

“…All the children were initially examined using a modified CE examination [12]. If this was either inconclusive or HD was not suspected, the children were included in this study.…”

“…Newer methods include a modified cold CE in which a radiographic investigation simultaneously as the CE is given can reveal the RAIR as well as visualize the contracted bowel segment, and the transition zone [12].…”

“…Therefore, at our pediatric surgery center, manometry was performed under general anesthesia in conjunction with a rectal biopsy. However, anorectal manometry has now been replaced by a radiological method for visualizing the RAIR using a modified CE [11,12]. With a modified CE, a cold contrast agent…”

“…All the patients also underwent preoperative contrast enema to identify the transition zone and if the recto anal relaxation reflex (RAIR) could be disclosed [9].…”
