Clinical Trial Summary

Currently, Placenta Accreta Spectrum (PAS) has two treatment options: hysterectomy (completely removing the uterus) and partial myometrial resection (resecting the part of the uterus affected by this pathology).

The present study is a feasibility study of a multicenter, randomized controlled clinical trial to be carried out in 3 health institutions. Patients who meet the inclusion criteria, after signing the informed consent, will be taken to the surgical procedure and before the start of the procedure they will be randomized to one of the two interventions, hysterectomy or partial myometrial resection, intra-surgical clinical outcomes will be explored and a follow-up will be carried out during the immediate post-surgical period (72 hours), in 7 to 12 days and at 42 days postpartum.

A sample size of 60 patients is estimated among the 3 health institutions, with an approximate duration of the study of 24 months.

Related Conditions & MeSH terms

• Placenta Accreta

Intervention

Procedure:
• Hysterectomy
Hysterectomy: An incision will be made above the level of the placenta, delivering the newborn. Uterotonics will be administered, and spontaneous delivery of the placenta will be awaited using gentle traction. The absence of spontaneous separation of the placenta will confirm the diagnosis of PAS, the patient will undergo to hysterectomy. The complete removal of the uterus will be attempted, including the cervix, the duration of the intervention and intraoperative blood loss will be recorded, as well as the damage to organs neighboring the uterus. In this arm of the study, to hysterectomy will be performed in 100% of patients
• Partial Myometrial Resection
Partial myometrial resection: The technique described by Palacios-Jaraquemada et al5. will be followed. Briefly, the uterus will be dissected to free it from the posterior wall of the bladder to the cervix. The vesico-uterine vessels will be ligated and the parametrial space will be visualized. The hysterotomy will be performed in the upper segment, immediately above the area of invasion of the myometrium. The entire invaded myometrium and the entire placenta will be removed. The uterus will repair itself in one or two layers. Intrauterine balloon tamponade will be used if indicated.
