Measurements of normal intestinal length in preterm infants is necessary in planning postoperative management following major bowel resection for necrotizing enterocolitis and other surgical conditions. A prospective autopsy study of 30 stillborn and newborn infants varying in gestational age from 19 to 40 weeks was undertaken to correlate gestational age with measurements of intact small intestine and colon. Only cases falling between the 10th and 90th percentile for body weight on the intrauterine growth curve were included. Mesenteric attachments were divided and intestine measured along the unstretched antimesenteric margin. Overall intestinal length for infants between 19 and 27 weeks gestation increased from 142 +/- 22 cm (mean +/- S.D.) to 304 +/- 44 cm for a comparable group over 35 weeks gestation. Knowing that jejunum, ileum, and colon more than double in length during latter gestation may have value in estimating prognosis and planning treatment for many preterm "short-gut" patients previously considered to have inadequate remaining intestine for survival.
对于坏死性小肠结肠炎及其他外科疾病行大肠切除术后的管理规划而言，测量早产儿的正常肠长度很有必要。我们对30例胎龄在19至40周之间的死产儿和新生儿进行了一项前瞻性尸检研究，以将胎龄与完整小肠和结肠的测量值相关联。仅纳入那些在子宫内生长曲线上体重处于第10至第90百分位数之间的病例。将肠系膜附着物分开，并沿未拉伸的系膜对侧缘测量肠管。孕19至27周婴儿的总肠长度从142±22厘米（平均值±标准差）增加到孕35周以上可比组的304±44厘米。了解到空肠、回肠和结肠在妊娠后期长度增加一倍以上，对于估计许多先前被认为剩余肠管不足以维持生存的早产“短肠”患者的预后和规划治疗可能具有价值。
