2175 Use of a Mathematical Model for the Prediction of Surgical Time in Robotic Myomectomy

Abstract

Study Objective To evaluate the factors associated with console time during robotic myomectomy. And to incorporate them in a mathematical formula that could predict the surgical time. Design Prospective and descriptive study. Setting Centro Medico Nacional 20 de Noviembre. Patients or Participants All patients who underwent robotic myomectomy. Interventions All the demographic and surgical information from patients who underwent a robotic myomectomy were collected before and during the procedure. The data collected were age, body mass index, number of myomas, size of the biggest myoma, parity, surgical bleeding, Docking time, console time and surgical time. Using the factors that correlated the most with the console time. A multiple linear regression model was made and a mathematical formula was developed for the prediction of console time. Measurements and Main Results In robotic myomectomy the only factor that correlates the most with surgical time is the fibroid´s size. We observed that there is a direct relationship between surgical time and fibroid´s size. Therefore console time can be predicted as: Surgical time= 84.316 + 13.089 (fibroid´s size). Conclusion Surgical time can be predicted with the aforementioned formula. We believe that the utilization of a mathematical model can be used to increase the efficiency in operating rooms.
