Brief summary

Excessive intraoperative bleeding remains a major challenge during open myomectomy and may lead to postoperative anemia and increased morbidity. Numerous methods have been proposed to minimize hemorrhage; however, evidence regarding their effectiveness in open surgery remains limited. This prospective randomized controlled trial aims to evaluate the effects of tourniquet application, uterine artery bulldog clamping, and no-compression techniques on intraoperative blood loss and postoperative hematological parameters in patients undergoing open myomectomy. A total of 120 patients undergoing open myomectomy will be randomly assigned to three groups: tourniquet group (n = 40), uterine artery bulldog clamp group (n = 40), and no-compression group (n = 40). The primary outcome is intraoperative blood loss. Secondary outcomes include hemoglobin (Hb) and hematocrit (Hct) levels at 24 and 48 hours postoperatively. Myoma volume will be calculated using the spherical formula based on the maximum myoma diameter. Statistical analyses will be performed using one-way analysis of variance (ANOVA) or the Kruskal-Wallis test, as appropriate.

Detailed description

This prospective randomized controlled trial aims to evaluate the effectiveness of different intraoperative bleeding control techniques during open myomectomy. Uterine leiomyomas are highly vascular tumors, and excessive intraoperative bleeding remains a major challenge, potentially leading to postoperative anemia and increased morbidity. Various strategies have been developed to reduce intraoperative blood loss, including mechanical and surgical methods aimed at temporarily reducing uterine arterial blood flow. However, most available evidence focuses on minimally invasive approaches, and data regarding open myomectomy remain limited. In this study, patients undergoing open myomectomy will be randomized into three groups according to the intraoperative bleeding control method: tourniquet application, bilateral uterine artery occlusion using bulldog clamps, and no compression. All procedures will be performed using a standardized surgical technique. The study aims to compare these techniques in terms of intraoperative blood loss and postoperative hematological parameters.

Interventions

Application of an elastic surgical tourniquet at the level of the lower uterine segment/cervix during open myomectomy to temporarily reduce uterine arterial blood flow. The tourniquet was maintained throughout myoma enucleation and released after completion of uterine repair.

PROCEDUREUterine artery bulldog clamp

Bilateral uterine arteries were surgically identified and temporarily occluded using bulldog vascular clamps during open myomectomy. The clamps were applied prior to myoma enucleation and removed after uterine repair to restore uterine perfusion.

Masking description

Due to the nature of the surgical interventions, blinding of participants and care providers was not feasible. However, outcome assessors and data analysts were blinded to group allocation.

Intervention model description

This study was designed as a prospective, randomized, parallel-group controlled trial. Participants were randomly assigned in a 1:1:1 ratio to one of three groups according to the intraoperative bleeding control method: tourniquet application, bilateral uterine artery occlusion using bulldog clamps, or no compression. Each participant received only one intervention, and no crossover between groups occurred.
