OBJECTIVE
This study was performed to determine whether large loop excision of the transformation zone (LLETZ) affects the outcome of pregnancy after 20 weeks gestation. METHODS: In a retrospective case control study 20 women who had undergone large loop excision of the transformation zone and were subsequently delivered at Ilsin Christian Hospital were identified between 1991 and 2003. 40 controls were identified and matched for age and parity from women delivered immediately before and after index cases. Maternal factors were analyzed such as pregnancy gestation, use of oxytocin, analgesia, whether labor was induced, mode of delivery, length of labor, estimated blood loss and birth weight of previous delivery. Perinatal outcome measured fetal weight and admission to the neonatal unit. RESULTS: There was no significant difference between the women who had undergone LLETZ and the controls except women delivered after LLETZ had increased rate of emergency cesarean section and amount of blood loss. CONCLUSION: Previous studies investigating pregnancy outcome after LLETZ have been generally reassuring and this study also have no difference. However, in this study women who were delivered after LLETZ had slight increased rate of emergency cesarean section, this may be related to adverse obstetrical history (recurrent abortion, infertility etc.). However socioepidemiological factors were not controlled and the small number of case groups were included, so larger controlled studies will be necessary to confirm this findings. |
