Comparison between robotic and laparoscopic myomectomy: the introduction of a multi-center observational cohort project

Objective: Uterine myomas are the most commonly encountered benign tumors of the uterus, and myomectomy may be a therapeutic option.With advancements in surgical devices, the minimally invasive approach has become the primary choice.Robot-assisted gynecological surgery is being increasingly performed; however, there is controversy regarding the advantages of robotic myomectomy (RM) compared to those of conventional laparoscopic myomectomy (LM).We design a multiple-center observational cohort project to compare the performance of RM and LM.Methods: In this project, participants will be stratified and assigned to the RM or LM group according to the suggestion of attending physicians' and patients' choices.We will recruit 222-444 patients, aged 20-80 years old, indicated for myomectomy. Results:The primary outcome will be the rate of conversion of RM and LM to laparotomy.The secondary outcome will include the intraoperative parameters, postoperative parameters, and duration of hospitalization.Additionally, we will attempt to generate a myoma score as the selection criteria for RM or LM.Conclusion: This observational cohort project to compare RM and LM may provide stronger evidence regarding the advantages and disadvantages of robotic surgery for the most commonly encountered benign gynecological tumors.
