To assess the diagnostic value of ultrasound (US) in clinically suspected acute intestinal intussusception in children, the authors prospectively compared US and enema studies in 83 episodes. None of the cases negative at US proved to be intussusception at enema study (negative predictive value = 100%). The sensitivity of US was 100%, and the specificity was 88%. Most of the sonograms were initially obtained and examined by residents. Several unsuspected abnormalities were also found with US. The authors conclude that a few months of training in US appears to be sufficient for high-accuracy investigation of clinically suspected intussusception, enabling selection of those patients in need of an enema.
为评估超声（US）对临床疑似小儿急性肠套叠的诊断价值，作者前瞻性地比较了83例患儿的超声检查和灌肠检查结果。超声检查阴性的病例在灌肠检查中均未证实为肠套叠（阴性预测值 = 100%）。超声的敏感性为100%，特异性为88%。大多数超声图像最初由住院医师获取并检查。超声检查还发现了一些未被怀疑的异常情况。作者得出结论，几个月的超声培训似乎足以对临床疑似肠套叠进行高精度检查，从而能够筛选出需要灌肠的患者。
