Introduction: The aim of our study was to compare long-term morbidity after elective and emergency cesarean delivery (CD).
Methods: A prospective cohort study was conducted in 200 women delivered by CD. Ultrasound examinations were performed transvaginally at 6 weeks and 18 months after CD. Clinical data were collected at the time of CD and after 18 months.
Results: In the group of 200 women, 29% underwent emergency and 71% elective CD. Then, 6 weeks and 18 months after CD, a severe scar defect was present in 7% and 5%, respectively (P = .4). After 18 months of CD, 17% (34/200) of women had evidence of adhesions of the vesicouterine pouch. Severe CD scar defects were significant predictors for adhesion formation in vesicouterine pouch (OR 3.14, 95% CI, 1.54-4.74), pelvic pain (OR 1.68, 95% CI, 0.22-3.14), dysmenorrhea (OR 2.12, 95% CI, 0.74-3.50), and dyspareunia (OR 1.38, 95% CI, 0.09-2.67). Uterine scar defects detected at 6 weeks after elective CD were detectable at 18 months in only 40% of cases, whereas uterine scar defects after emergency CD were still detectable in 87% of cases.
Conclusion: Uterine scar defects are more frequent at 18 weeks after emergency CD, than after elective CD (40% vs 87%). Women with severe scar defects have higher risk of adhesion formation, dysmenorrhea, dyspareunia, and chronic pelvic pain.
