The course of delivery and the post partum period of 211 gravidae with closure of the cervix during pregnancy were compared with a compatible collective of another 221 gravidae without surgical closure. There were significant differences in some respects: The duration of labor (primiparae: 9,2 hours, multiparae: 6,7 hours) was longer than in the control-group (primiparae: 8,1 hours, multiparae: 5,0 hours); the necessity of administration of drugs and the frequency of dystocia (primiparae: 13%, multiparae: 9,2%) was higher than in the control-group (primiparae: 1,0%, multiparae: 0%). These and the higher incidence of lacerations of the cervix (13,4% respectively 1,7%) will be due to the scar, caused by the suture in the cervix. The rate of caesarean section was significantly higher (9,5% respectively 4,1%). There were more complications in disconnecting of the placenta. These and the higher rate of dystrophic newborn could be correlated with anamnestic dispositions of the gravidae. The higher rate of perinatal mortality (9,9%) than in the controlgroup (3,6%) is associated with the higher rate of prematurity (22,1%) than in the control-group (8,5%). A higher incidence of malformation was not observed, but a higher rate of neurological complications in the newborn. The post partum period of the mother was not significantly different than those of the control-group
将211例孕期宫颈闭合的孕妇的分娩过程及产后情况与另外221例未进行手术闭合的对照孕妇群体进行了比较。在某些方面存在显著差异：产程（初产妇：9.2小时，经产妇：6.7小时）比对照组（初产妇：8.1小时，经产妇：5.0小时）更长；用药必要性及难产发生率（初产妇：13%，经产妇：9.2%）高于对照组（初产妇：1.0%，经产妇：0%）。这些以及宫颈裂伤发生率较高（分别为13.4%和1.7%）是由于宫颈缝合造成的瘢痕所致。剖宫产率显著更高（分别为9.5%和4.1%）。胎盘剥离时并发症更多。这些以及营养不良新生儿发生率较高可能与孕妇的既往情况有关。围产期死亡率较高（9.9%）高于对照组（3.6%）与早产率较高（22.1%）高于对照组（8.5%）有关。未观察到畸形发生率更高，但新生儿神经并发症发生率更高。母亲的产后情况与对照组无显著差异
