Tek kat ve çift kat onarımın rezidüel miyometriyal kalınlık, istmosel oluşumu ve jinekolojik bozukluklar üzerine etkisi: Prospektif Randomize Kontrollü Bir Çalışma.

Abstract

Abstract: Physicians are making great efforts to decrease the long-term complications of the cesarean section such as placental adherent syndromes, uterine scar pregnancies, uterine rupture, abnormal menstrual bleeding, or isthmocele. There is a controversy about the closure technique of the cesarean incision. The purpose of that study was to compare the impact of single layer versus double-layer closure of the hysterotomy incision on the residual myometrial thickness, isthmocele, menstrual disorders, dysmenorrhea, and dyspareunia. Material and Method A prospective randomized cohort study has been performed in a tertiary center named Bursa Yuksek İhtisas Training Research Hospital between July – October 2021. Patients were randomly assigned to each procedure (1:1) to the Single Layer Locked Continuous group and Double-layer Continuous un-locked group as uterine closure technique. Patients were examined via transvaginal ultrasound to evaluate the isthmocele occurrence, residual myometrium thickness, and inquired about menstrual properties, dysmenorrhea, and dyspareunia. Patients were also divided into groups via underwent first cesarean and more than one cesarean. Results: The numbers of the women whose hysterotomy incision was closed by single-layer locked continuous( SLLC) technique and double-layer un-locked continuous(DLUC) technique 68 and 71 respectively. There was no statistically significant difference in terms of demographic variables, obstetric history, post-operative complications, neonatal outcomes. The comparison of these groups revealed that there was no significant difference in terms of post-menstrual bleeding, heavy menstrual bleeding, post-coital bleeding, dysmenorrhea, dyspareunia. The incisional residual myometrial thickness was higher in the DLUC group with a p-value of 0,007. Six patients in SLLC and 5 patients in the DLUC group have detected isthmocele (p: 0,941). Patients have also been categorized as women who undergone their first cesarean section (SLLC n: 33 versus DLUC, n:33) and more than one cesarean section (SLLC n: 35 versus DLUC, n:38). Comparing the patients in these subgroups also did not differ significantly in terms of isthmocele occurrence, menstrual disorders, or residual myometrial thickness. Conclusion: No significant difference had occurred in terms of isthmocele incidence, or menstrual disorders comparing the single layer versus double-layer closure. However, women whose hysterotomy insicions were closed with double-layer un-locked continuous technique have a thicker resudial myometrium than single layer closure group especially women who underwent repeated cesarean.
