This study reports the use of pelvic ultrasound scanning in childhood onset anorexia nervosa. The aim was to determine the weight and weight for height ratio (wt/ht) that would correspond with ovarian and uterine maturity and therefore offer the optimal opportunity for the start or resumption of menstruation. On initial assessment, all children had mean weight, wt/ht, ovarian and uterine volumes significantly below expected. At follow up, half the children had started or resumed menstruation. When compared with those who had persisting amenorrhoea, the recovered children had a significantly higher mean weight (48.4 kg v 43.8 kg), mean wt/ht (96.5% v 87.5%), mean ovarian volume (6.2 ml v 4.9 ml), and mean uterine volume (14.6 ml v 10.8 ml). The study indicates that conventional target weight and wt/ht in anorexia nervosa may be too low to ensure ovarian and uterine maturity, and that pelvic ultrasound, which is well tolerated by this group of children, is a useful addition to their management.
本研究报告了盆腔超声扫描在儿童期起病的神经性厌食症中的应用。目的是确定与卵巢和子宫成熟度相对应的体重及身高体重比（wt/ht），从而为月经初潮或月经恢复提供最佳时机。在初次评估时，所有儿童的平均体重、wt/ht、卵巢及子宫体积均显著低于预期。在随访时，半数儿童已开始或恢复月经。与持续闭经的儿童相比，月经恢复的儿童平均体重显著更高（48.4千克对43.8千克）、平均wt/ht显著更高（96.5%对87.5%）、平均卵巢体积显著更大（6.2毫升对4.9毫升）、平均子宫体积显著更大（14.6毫升对10.8毫升）。该研究表明，神经性厌食症中传统的目标体重和wt/ht可能过低，无法确保卵巢和子宫成熟，并且盆腔超声在这组儿童中耐受性良好，是其治疗管理中的一项有用补充。
