Protocol for a Modified Vaginal Pipe For Total Laparoscopic Hysterectomies: Experimental Research

Background: The Vagi-Pipe(R) is a useful device for performing a total laparoscopic hysterectomy. The conventional model of the Vagi-Pipe(R) is unable to grasp the uterus during colpotomy for recovery of the resected uterus. However, the modified C-Type Vagi-Pipe(R) model has a shape that allows insertion into the vagina without removing the uterus manipulator. In this study, we will prospectively investigate the safety and efficacy of the C-Type Vagi-Pipe(R) in total laparoscopic hysterectomies. Materials and methods: In total, 25 female subjects aged between 20 and 60 years with uterine fibroids or adenomyosis will be included. Patients with complications regarded as unsuitable for this study by the investigators will be excluded. The C-Type Vagi-Pipe(R) will be used rather than the conventional Vagi-Pipe(R) when performing a total laparoscopic hysterectomy. The primary endpoint will be safety and the secondary endpoints will be operation time, bleeding volume, and presence of complications. Ethics and dissemination: The protocol was approved by the institutional review boards. Written informed consent will be obtained from all patients before registration in accordance with the Declaration of Helsinki. Results of the study will be disseminated via publications in peer-reviewed journals.
