Brief Summary

Caesarean section (CS) is the commonest major operation performed on women worldwide with progressively rising incidence. Consequently, long-term adverse sequelae due to uterine scar defect have been increasing. Given the association between uterine scar defect and gynecological symptoms, obstetric complications and potentially with subfertility, it is important to elucidate the etiology in order to develop preventive strategies. Surgical technique of uterine incision closure seems to be the most important determinant of defect formation. The aim of this prospective randomized study is to evaluate specifically the influence of inclusion versus exclusion of the endometrium during suturing the uterine incision on the risk to develop uterine scar defect.
