Comparative analysis of classical primary continuous and novel technique uterine suturing methods on uterine scar formation after caesarian section: a prospective clinical study.

OBJECTIVES: The study investigated isthmocele rate, residual myometrium thickness, blood loss, and closure lengths through comparing the classical primary continuous suturing (CPCS) and novel technique uterine suturing (NTUS) after caesarian section.

MATERIAL AND METHODS: A total of 402 C/S patients were included in this single-center prospective clinical study. All patients were divided into two groups according to suture technique. Classical primary continuous suturing (CPCS) was applied to the patients in Group 1, while the novel technique uterine suturing (NTUS) was applied in Group 2 as Z suture on both corners and 8 sutures in the remaining middle part incision closure.

RESULTS: Patients in the NTUS group bled less than in the CPCS groups (p < 0.0001). Incision length after closure was longer in the CPCS than in the NTUS (p < 0.0001). Similarly, the number of sutures we applied was higher in the CPCS (p < 0.0001). In comparison of residual myometrium thickness, the mean values measured 197 ± 50 mm in the NTUS and 146 ± 39 mm in the CPCS (p < 0.0001). Residual myometrium thickness showed a negative strong correlation with incision length after closure (r = -0.436; p < 0.0001), how many times the needles have been passed (r = -0.423; p < 0.0001) and time for suturing (r = -0.237; p < 0.0001). NTUS and CPCS groups were similar in comparison to isthmocele.

CONCLUSIONS: The NTUS, termed as Erkayiran's suture, showed a successful reflection in our surgical cesarean section application compared to the classical suture. Although the occurrence of isthmocele in patients was similar, results were quite successful operationally in terms of both minimal blood loss and increased residual myometrium thickness.
