Brief Summary

Hysteroscopic Isthmocele repair on IVF outcome It aims to assesse the efficacy of Hysteroscopic CS scar defect repair on the clinical pregnancy rate after embryo transfer. Patients who were diagnosed with significant caesarean section scar defect and had a previous unsuccessful ongoing pregnancy after embryo transfer of one or more euploid embryo and planning for another trial of one euploid embryo transfer will be assed for study eligibility. Twenty five of them will be be randomized to hysteroscopic repair before having embryo transfer. and 25 will go directly for embryo transfer. Clinical pregnancy rate is the primary outcome.

Outcome Measures

Primary Outcomes (1)

  • Rate of Clinical pregnancy

    detection of intrauterine pregnancy with a detectable fetal heart pulsation by transvaginal ultrasound scan

    at 7 weeks of gestation or beyond

Secondary Outcomes (5)

  • Rate of Complications following hysteroscopic CS scar repair

    up to 6 weeks

  • Rate of Need of aspiration of intrauterine fluid

    During the preparation of embryo transfer. Through study completion, an average of 1 year

  • Rate of Early pregnancy complications

    12 weeks gestation

  • Rate of Caesarean section scar dehiscence or rupture

    Within 40 weeks of pregnancy

  • Rate of delivery of a living baby

    Within 40 weeks of pregnancy

Hysteroscopic CS scar defect repair

EXPERIMENTAL

Patient who is randomized to the hysteroscopic repair of CS scar defect will be prepared to have the surgery postmenstrual. The surgery will be under general anasthesia. The participants will be placed in the lithotomy position. The cervix will be visualized using a Sims speculum and grasped using a single-toothed tenaculum, and the cervix, fornix, and vagina will be cleaned. Dilatation of the cervix till 7 mm. Introduce the resctoscope through the cervix. The surgical correction of the isthmocele is done by resection of the inferior and superior edges or just the inferior edge of the defect with a resectoscopic loop, using pure cutting current, until reaching the muscular layer. Coagulation of fragile vessels at the base or even entire niche. At the end of procedure, flow and pressure of distending medium can be reduced to ensure adequate haemostasis. After that the patient will be prepared for another euoploid embryo transfer.

Procedure: Hysteroscopic CS scar defect repair

Expectant management

NO INTERVENTION

Patient who is randomized to the expectant management will be prepared for another embryo transfer for euoploid embryo.

Interventions

Dilatation of the cervix till 7 mm. Introduce the resctoscope through the cervix. The surgical correction of the isthmocele is done by resection of the inferior and superior edges or just the inferior edge of the defect with a resectoscopic loop, using pure cutting current, until reaching the muscular layer. Coagulation of fragile vessels at the base or even entire niche. At the end of procedure, flow and pressure of distending medium can be reduced to ensure adequate haemostasis.

This prospective randomized controlled will be conducted at Healthplus fertility center. The population of the study will be Patients who was diagnosed with significant caesarean section scar defect and had a previous unsuccessful ongoing pregnancy after embryo transfer of one or more euploid embryo and planning for another trial of one euploid embryo transfer. Twenty five of them will be be randomized to hysteroscopic repair before having embryo transfer. and 25 will go directly for embryo transfer. Clinical pregnancy rate is the primary outcome. Secondary outcomes are Complications following hysteroscopic CS scar repair, the need of aspiration of intrauterine fluid before embryo transfer, early pregnancy complications, Caesarean section scar dehiscence or rupture and live birth rate.
