Plain abdominal radiographs were studied in 280 children aged between one day and fourteen years to assess the age-related width of the extra-peritoneal fat. At the same time the limitations of assessing the size of the right side of the liver, the lower pole of the spleen and the psoas shadow were investigated. A significant rise in the evaluation of this method was only obtained after the sixth year and this was 86% in relation to the right lobe of the liver and 36% in relation to the lower pole of the spleen. From this age onwards, the preperitoneal fat is demonstrable in 94% of cases. The investigation suggests that from the sixth year onwards, the absence of the extra peritoneal fat line is an indirect indicator that there is intra-peritoneal fluid or a retro-peritoneal tumour.

对280名年龄在1天至14岁之间的儿童进行了腹部平片研究，以评估与年龄相关的腹膜外脂肪宽度。同时，研究了评估肝脏右侧、脾脏下极和腰大肌阴影大小的局限性。只有在6岁以后，该方法的评估才有显著提高，相对于肝脏右叶为86%，相对于脾脏下极为36%。从这个年龄开始，94%的病例可显示腹膜前脂肪。该研究表明，从6岁起，腹膜外脂肪线的缺失是腹腔内有液体或腹膜后肿瘤的间接指标。埃克
