The efficacy between cervical-lifting suture and lower B-Lynch suture in placenta previa: a retrospective cohort-study.

PURPOSE: This study is performed to evaluate and compare the efficacy of cervical-lifting suture and lower B-Lynch suture in different severity of placenta previa associated with lower uterine segment bleeding.

METHODS

We evaluated the effectiveness of cervical-lifting suture (n = 51) and lower B-Lynch suture (n = 137) in stopping the bleeding from lower uterine segment. Additionally, we used different statistical methods, including overall analysis, subgroup analysis and approximate randomization analysis, to evaluate the efficacy of the two assessments.

RESULTS

The medical records of these 188 participants were extracted and all of the patients were followed up for six weeks. The majority of patients were multipara and complicated with previous cesarean delivery and abnormal adherent placenta. The median intraoperative blood loss and the median amount of red blood cell transfusion were lower in the cervical-lifting suture group in comparison to the lower B-Lynch suture group.

CONCLUSION

Our study provides evidence that cervical-lifting suture has less intraoperative blood loss and red blood cell transfusion for controlling lower uterine segment bleeding in placenta previa.
