Thirty-seven patients undergoing routine investigation for malabsorption were given radio-opaque pellets (ROP) which were compared with polyethylene glycol and chromic oxide as continuous faecal markers. Percentage recovery of all markers showed a wide range. The recovery of all markers was very similar, and radio-opaque pellet-corrected daily faecal fat correlated very closely with PEG-and chromic oxide-corrected fat results. Estimation of ROP is precise, simple, and minimises faecal handling. ROP are suitable for routine use in faecal fat studies and have advantages over markers used at present.
37名因吸收不良接受常规检查的患者被给予不透X线的小丸(ROP),并将其与聚乙二醇和氧化铬作为连续粪便标记物进行比较。所有标记物的回收率显示出很大的范围。所有标记物的回收率非常相似,并且经不透X线小丸校正的每日粪便脂肪与经聚乙二醇和氧化铬校正的脂肪结果密切相关。ROP的测定精确、简单,且将粪便处理减至最少。ROP适用于粪便脂肪研究的常规使用,并且比目前使用的标记物具有优势。
