Abstract

Background: Anorectal malformation is often found in neonates with the prevalence of 1 every 5000 birth. Ultrasonography (US) is the imaging of choice to determine the level of distal end of rectum and the presence of fistula. This examination is easy, not invasive, doesn't need special preparation. can be done earl ier and only need 3-5 minutes to perform. Therefore, morbidity can be reduced especially in the form of distention and its complication. Objective: To assess the sensitivity and specificity of infracoccygeal US in babies with ARM and comparing it to distal loopography examination. Method: This research is an analytical observationaJ study, comparing infracoccygeal US with distal Lopography in babies with ARM. On each baby, we performed examination twice, infracoccygeal US and distal loopography after colostomy. The result is interpreted by radiologist. We analyze the sensitivity and specificity of the tests. Result: From 20 samples that we examine by infracoccygeal US and distal loopography to determine the height of the distal end of rectum, 16 have the same result, 2 with low position and 14 with high position. On examination to determine the presence of fistula, we found 14 sample with the same results, 3 with fistula and 11 without fistula Conclusion: Compared to distal ioopography, infracoccygeal US had the sensitivity of 0,5 and specificity of 0,88 to determine the height of the di stal end of rectum, while to detect the presence of fistula infracoccygeal US had the sensitivity of 0,7S and specificity of 0,69
