A lymphoid follicular pattern was noted more frequently when high-density (100% w/v) replaced low-density (58% w/v) barium in children undergoing double-contrast barium enema examinations. Therefore, a retrospective study was undertaken to compare the presence of follicles seen in 24 consecutive patients under 10 years old given low-density barium with that of 50 patients given high-density barium. The high-density studies revealed follicles in 90% of the children compared with 46% of the children having low-density studies. All follicles were less than 2 mm in diameter. An aphthoid appearance was present in nine of these 50 children. The most common indications for the high-density examination were rectal bleeding and abdominal pain. The final diagnosis was normal bowel in more than two thirds; no child under six years old given high-density barium had inflammatory bowel disease. There was no correlation between final clinical diagnosis and the presence, extent, or severity of the lymphoid follicular pattern.
在接受双重对比钡灌肠检查的儿童中，当高密度（100% w/v）钡剂取代低密度（58% w/v）钡剂时，更频繁地观察到淋巴滤泡模式。因此，进行了一项回顾性研究，以比较24例连续接受低密度钡剂检查的10岁以下儿童与50例接受高密度钡剂检查的儿童中滤泡的出现情况。高密度检查显示90%的儿童有滤泡，而低密度检查的儿童中这一比例为46%。所有滤泡直径均小于2毫米。这50名儿童中有9名出现口疮样表现。高密度检查最常见的指征是直肠出血和腹痛。最终诊断超过三分之二为肠道正常；接受高密度钡剂检查的6岁以下儿童均无炎症性肠病。最终临床诊断与淋巴滤泡模式的存在、范围或严重程度之间无相关性。
