Single-port access (SPA) laparoscopic myomectomy with uterine artery ligation via a retroperitoneal approach is feasible in women with large uterine leiomyoma

Objective: Uterine artery ligation (UAL) at the time of myomectomy has shown to decrease blood loss during the operation. However, little is known about the efficacy and feasibility of UAL during single-port access (SPA) myomectomy. The present study was performed to investigate the clinical benefits of UAL in SPA myomectomy and to provide details of the surgical techniques. Materials and methods: A retrospective and comparative review on the surgical outcomes of the patients who underwent SPA myomectomy with UAL and those who underwent SPA myomectomy without UAL was conducted. UAL was performed at its origin from the internal iliac artery via a retroperitoneal approach. Results: A total of 56 women who received SPA myomectomy were reviewed (24 patients received SPA myomectomy with UAL while 32 patients received SPA myomectomy only). The median weight of total resected leiomyomas was heavier for the patients who received UAL than those who did not receive UAL [210.0 g (range: 171.5–335.0 g) vs. 119.0 g (62.5–265.0 g), p = 0.023]. However, no differences in total operative time, estimated blood loss, perioperative hemoglobin changes, use of postoperative analgesics and postoperative complications between the two groups were seen. Conclusion: Obtaining similar surgical outcomes between the patients who received UAL with larger leiomyomas and those who did not receive UAL with smaller leiomyomas suggests that UAL is a feasible surgical approach to reduce blood loss during SPA myomectomy. Detailed descriptions of the surgical techniques are provided in the present report
