Abstract

Introduction: One of the complications of cesarean is cesarean section defect (Niche syndrome). One of the etiologies of this disease is incomplete or incorrect closure of the cesarean section, without closing the deep muscle layers due to improper sutures or not allocating enough time for this. The type of suture used to close the cesarean section is an important challenge in predicting this complication. Therefore, our study was performed to determine the relationship between the type of suture used and the incidence and severity of cesarean section defects in patients with a history of cesarean section. Methods: This study was a prospective clinical trial. 50 patients underwent cesarean section and were randomly divided into two groups of 25 (chromic suture group and vicryl suture group). After 2 months, patients were called to the clinic and underwent vaginal ultrasound by a specialist doctor for cesarean section defects. The information included: the incidence of cesarean section defects, the type of suture used and the amount of cervical dilatation were recorded in a pre-prepared questionnaire. Data was collected by SPSS version 22 and data analysis was performed using frequency distribution tables and statistical tests. Results: Of the 50 patients studied, 8 (16) had Niche. Also, 9 patients (18) had cervical dilatation. The results showed that there was a statistically significant difference between the frequency distribution of Niche according to the type of suture used in the studied patients and the frequency of Niche in patients who used chrome thread was significantly higher (p = 0.021). Also, no statistically significant difference was found between the frequency distribution of Niche in terms of cervical dilatation in the studied patients (p = 0.196). There was no statistically significant difference between the frequency distribution of cervical dilatation according to the type of suture used in the studied patients (p = 0.325). Conclusion: According to results, can be concluded that the use of chromic thread is associated with more cesarean defects. Therefore, the use of Vicryl thread instead of chromic is recommended to reduce the incidence of cesarean scar defects.
