Bilateral Uterine Artery Ligation Versus Pericervical Mechanical Tourniquet Application in Reducing Intraoperative Blood Loss During Transabdominal Myomectomy.
Bilateral Uterine Artery Ligation Versus Pericervical Mechanical Tourniquet Application in Reducing Intraoperative Blood Loss During Transabdominal Myomectomy.
The goal of this clinical trial is to compare two surgical techniques for reducing blood loss during transabdominal myomectomy in women with symptomatic uterine fibroids. The main question it aims to answer is whether bilateral uterine artery ligation reduces intraoperative blood loss more effectively than pericervical mechanical tourniquet application, without increasing operative complications. Researchers will compare bilateral uterine artery ligation with pericervical mechanical tourniquet application during open myomectomy to evaluate blood loss and surgical safety. Participants will undergo elective transabdominal myomectomy and will be randomly assigned to one of the two vascular control techniques before myoma enucleation.
Uterine fibroids are among the most common benign gynecologic tumors and may cause heavy menstrual bleeding, pelvic pain, pressure symptoms, infertility, and other reproductive problems. For women who desire uterine preservation, myomectomy remains an important treatment option. In patients with large, multiple, or deeply located fibroids, transabdominal myomectomy is still widely performed. However, one of its major challenges is significant intraoperative bleeding, which may increase operative difficulty, prolong surgery, increase postoperative morbidity, and raise the need for blood transfusion.
Several methods have been used to reduce bleeding during myomectomy. Among the commonly used surgical approaches are bilateral uterine artery ligation and pericervical mechanical tourniquet application. Bilateral uterine artery ligation reduces uterine arterial inflow before myoma enucleation and may provide sustained hemostasis during surgery. Pericervical tourniquet application is a simple mechanical method that temporarily compresses the uterine vessels at the cervico-isthmic level during the procedure. Although both techniques are used in practice, comparative evidence remains limited, and further evaluation is needed to determine the more effective and safe method for blood loss reduction during fertility-sparing surgery.
This study is a prospective, randomized, comparative clinical trial conducted at the Department of Obstetrics and Gynecology, Kasr Al-Ainy Hospital, Cairo University, Egypt. Women scheduled for elective transabdominal myomectomy for symptomatic uterine fibroids will be recruited and randomized into two parallel groups. One group will undergo bilateral uterine artery ligation before myoma enucleation, while the other group will undergo pericervical mechanical tourniquet application using a Foley catheter at the level of the internal os before myoma enucleation. All procedures will be performed by the same experienced surgical team under standardized perioperative conditions to reduce inter-operator variability.
During surgery, after the assigned vascular control technique is applied, myoma enucleation and uterine repair will proceed according to a standardized operative technique. Blood loss assessment will include intraoperative blood loss measured from surgical swabs and suctioned blood, as well as postoperative blood loss measured from the intraperitoneal drain. The trial is designed to determine whether bilateral uterine artery ligation provides superior hemostatic control compared with pericervical mechanical tourniquet application, while also evaluating perioperative safety and recovery outcomes.
