The Development of a New Uterine Manipulation Method during Minimally Invasive Radical Hysterectomy

Abstract

Study objective: The use of a vaginal uterine manipulator may compromise the oncological outcomes of patients with cervical cancer undergoing minimally invasive radical hysterectomy (MIS-RH). We aimed to describe the safety and efficacy of a novel uterine manipulation device during MIS-RH.

Design: Retrospective study.

Setting: A university hospital and a tertiary care hospital.

Patients: Patients with early-stage cervical cancer who were treated with MIS-RH.

Interventions: We developed the U-traction, a new device that consists of a 65-mm half-curved cutting needle with a 2.5-mm polyester tape (45-cm long), and investigated its utility to manipulate the uterus during MIS-RH.

Measurements and main results: This study describes the utility and safety of the U-traction for uterine manipulation during laparoscopic or robotic RH in 8 patients with cervical cancer. Uterine manipulation was successfully and safely performed using the U-traction during laparoscopic or robotic RH in patients with cervical cancer without any complications. The application time was less than 5 minutes. In all cases, the use of a vaginal manipulator, an additional incision for an extra port, or the need for assistant surgeons for uterine manipulation was avoided.

Conclusion: The novel U-traction device allows for easy and reproducible uterine manipulation during MIS-RH. With this device, the use of a vaginal uterine manipulator can be avoided, and MIS-RH can be safely performed without the need for an assistant surgeon for uterine manipulation.
