A prospective study was undertaken to determine the incidence of occult hematochezia in enterally fed low-birth-weight neonates (less than 1800 g at birth). The relationship of this occult hematochezia to the development of necrotizing enterocolitis (NEC) was then analyzed. Daily stool specimens from 95 neonates were tested for occult blood during the first six weeks of life. Fifty-four (58%) of the 95 neonates had one or more blood-positive stools. Six neonates (6.3%) developed NEC. Necrotizing enterocolitis occurred in only two of the 54 neonates with one or more blood-positive stools vs four of the 41 neonates with blood-negative stools only. Presence of occult blood in the stools did not correlate with development of NEC.
进行了一项前瞻性研究，以确定经肠道喂养的低体重新生儿（出生时体重小于1800克）隐匿性便血的发生率。然后分析了这种隐匿性便血与坏死性小肠结肠炎（NEC）发生发展的关系。在95名新生儿出生后的前六周，每天采集粪便样本检测潜血。95名新生儿中有54名（58%）出现一次或多次潜血阳性的粪便。6名新生儿（6.3%）发生了NEC。在54名有一次或多次潜血阳性粪便的新生儿中，只有2名发生了坏死性小肠结肠炎，而在仅粪便潜血阴性的41名新生儿中，有4名发生了坏死性小肠结肠炎。粪便中潜血的存在与NEC的发生发展无关。
