Summary

This study compares two ways of closing the uterus during cesarean delivery. In one group, the decidual layer near the uterine cavity is included in the suture. In the other group, this layer is left out. The study will examine whether these two methods differ in how well the uterine scar heals 6 to 9 months after surgery.

Women having an elective cesarean delivery will be randomly assigned to one of the two closure methods. Scar healing will be assessed by ultrasound after delivery. The goal is to determine whether one method is associated with better cesarean scar healing and fewer scar defects.

Conditions

  • Isthmocele
  • Cesarean Scar Diverticula

Interventions

PROCEDURE

Single-Layered Non-Locked Closure with Decidual Inclusion

During the cesarean section, the uterine incision is closed with a single-layered, non-locked suture. In this technique, the decidua (the uterine lining) is included in the closure. This means that the endometrial cells are part of the suture, potentially influencing the healing process of the uterine scar. Goal: The idea is that including the decidua may promote better healing and scar formation, reducing the risk of complications such as isthmocele and improving long-term uterine health.

PROCEDURE

Single-Layered Non-Locked Closure with Decidual Sparing

Procedure: In this technique, the uterine incision is also closed using a single-layered non-locked suture, but the decidua is excluded from the closure. The suture is placed only through the myometrium (muscle layer) of the uterus, leaving the decidua out of the scar tissue. Goal: The intent is to observe if sparing the decidua results in better scar healing and a lower risk of isthmocele formation, as well as fewer long-term complications.
