The role of bedside assistant during robot assisted radical prostatectomy: Is more experience better? Analysis on perioperative and clinical outcomes.

OBJECTIVES

To analyze the impact of the bedside assistant's experience during RARP. It is believed that the outcome of robotic surgery during Robot Assisted Radical Prostatectomy (RARP) for prostate cancer depends not only on the console surgeon's experience.

MATERIALS AND METHODS

All consecutive RARPs from January 2017 to March 2018 were sourced from a prospectively maintained database. All cases were performed by the same surgeon. He was supported by three bedside assistants: one with bedside and console experience, one only with relevant bedside experience, one basically inexperienced. The patient's parameters analyzed: age, Body Mass Index (BMI), previous abdominal surgery, prostate volume (by TRUS), pre-operative PSA, bioptic grading. Surgical outcomes analyzed included skin-to-skin operative time and estimated blood loss; clinical outcomes included length of hospital stay and time to catheter removal; the oncological outcome was represented by positive surgical margin rate.

RESULTS

A total of 116 RARPs were identified: 38 RARPs were performed with the console experienced bedside assistant, 38 with the experienced one, 40 with the novice one. The variables were similar between the three groups. As far as outcomes are concerned, there were no statistically significant differences between the three bedside assistants in terms of operative time, estimated blood loss, length of stay, days of catheterization, positive surgical margin rate.
