[Conization in pregnancy and its significance for the further course of pregnancy].

The influence of cold knife conisation on further progression of pregnancy was analysed in 28 patients, who underwent the operation during pregnancy. 13 women were operated on within the first 16 weeks of gestation (group I) and were compared to 15 patients, where conisation was done in the 17th week or later (group II). In the first group, deliveries were found in the 39th week of pregnancy compared to 34 weeks in the second group (p.05). A statistical significant difference concerning the further duration of pregnancy after conisation was found: 25 weeks in group I vs. 11 weeks in group II (p. 0012). There was no difference, however, in radicality whether conisation was done in early or late pregnancy. Our final conclusion is, that a preterm delivery occurs significantly more often in women who underwent conisation after 16th week of gestation.
