Impact of Parity on Early Cesarean Scar Healing

Abstract

Background: with increasing cesarean delivery rate the cesarean scar defects and related consequences should be evaluated. Aim of the work: this study aimed to assess impact of parity on cesarean scar wound healing. Methods: a prospective observational study was conducted on 51 females with singleton term pregnancy that underwent uncomplicated prelabor primary cesarean section. 6 weeks later they underwent saline hystrosalpingography. Females with medical diseases that can affect the healing process or received medications can affect wound healing as corticosteroids or anticoagulant were excluded. Women used intrauterine device as a contraceptive method inserted during CS, women with any structural uterine abnormality as cervical stenosis or fibroid uterus or with pelvic infection at the time of saline hystrosalpingography were excluded from this study. Results: 75% of the primiparous had CS niche, while, 82.9% of the multiparous group had CS defect (p=0.512). The most prevalent shape of CS defect in the participants was the triangular shape (45.1%) followed by irregular defect (31.4%). The anterior myometrial thickness and the residual myometrial thickness were significantly higher among primiparous women with negative correlation between parity, anterior and residual myometrial thickness (rho = - 0.917 and -0.753 respectively). Conclusion: parity was associated with significant reduction of both the anterior and residual myometrial thickness.
