Retracted: A randomized controlled study comparing two uterine sparing techniques in conservative management of placenta accreta spectrum.

OBJECTIVES

To compare the efficacy and safety of two uterine sparing techniques in conservative management of placenta accreta spectrum (PAS).

METHODS

This multicenter randomized controlled study was conducted from January 1, 2017 to December 31, 2020 at two university hospitals. Patients were randomly allocated into two groups; Group 1 was managed by Assar's technique and Group 2 was managed by Shehata's technique. Operative time, blood loss, operative complications (organ or vessel injury), and postoperative complications (early and late) were reported. Success of the technique, units of blood transfusion, and intensive care unit admissions were recorded.

RESULTS

Demographic data in both groups were not significantly different. The mean gestational age at the delivery time was 36 weeks in both groups. Operative time was 120 (100-140) minutes and 75 (60-100) minutes in Assar's and Shehata's techniques, respectively (P < 0.001). Blood loss was higher in Shehata's technique than in Assar's (P < 0.001). Intensive care unit admissions were minimal in both groups. Operative complications were comparable in both groups. The success of Assar's and Shehata's techniques in uterine preservation was 85% and 95%, respectively.

CONCLUSION

Both techniques were safe and successful in uterine sparing. Therefore, we recommend these techniques for conservative management of PAS.
