100 g of spinach a day was added to the hospital diet of fifty-four patients with suspected malabsorption. Hyperoxaluria was found in thirty-eight patients; all of them had steatorrhoea. No patient with steatorrhoea had a urinary oxalate excretion of less than 40 mg a day. Ten other patients had hyperoxaluria, but the faecal fat determinations were regarded as unreliable in almost all and malabsorption could not be confirmed. It is suggested that in clinical practice determination of urinary oxalate after an oral load of oxalate could replace faecal fat determination in most patients with suspected malabsorption.
每天100克菠菜被添加到54名疑似吸收不良患者的医院饮食中。在38名患者中发现了高草酸尿症；他们都有脂肪泻。没有脂肪泻的患者每日尿草酸排泄量低于40毫克。另外10名患者有高草酸尿症，但几乎所有患者的粪便脂肪测定都被认为不可靠，吸收不良无法得到证实。建议在临床实践中，对大多数疑似吸收不良的患者，口服草酸盐负荷后测定尿草酸可以替代粪便脂肪测定。
