The technique was first described in 1997. It can stop postpartum hemorrhage without the need for pelvic surgery and potentially preserving fertility. It is regarded as "the best form of surgical approach for controlling atonic PPH as it helps in preserving the anatomical integrity of the uterus."
Absorbable suture can be left in situ, and would typically not lead to problems with future pregnancies.
