Robotic-assisted radical prostatectomy: a multicenter experience with the Senhance Surgical System.

PURPOSE: Robotic-assisted surgery for radical prostatectomy is becoming a standard treatment, and respective implementations are expanding. The Senhance Surgical System is a robotic system with existing but limited data on radical prostatectomy, including a lack of multicenter study experiences. The TRUST study aims to fill this gap and explores observations for radical prostatectomy with the Senhance Surgical System. METHODS: Between August 2019 and November 2022, 375 patients met inclusion criteria from two European sites. Patients' surgical procedure times, data on conversion, malfunction, adverse events, and pain scores were registered and evaluated. Outcomes were calculated for both sides, combined as a total and compared between the initial (1st-150th case) and later (> 150th case) period. RESULTS: The median operating time was 190 min (IQR: 167.5-215.0) and the median docking time was 3 min (IQR: 2.0-5.0). Eighteen cases (4.8%) were converted to standard laparoscopy and two (0.5%) to open. Two perioperative (0.5%) and eleven postoperative adverse events (2.9%) occurred, mostly (83.3%) categorized as mild. Pain scores were reduced from an average of 3.4 (± 1.4) on the postoperative day to 0.9 (± 0.7) at discharge. Compared to our previous data and based on a comparison between our initial and later period, operating time seems to plateau. However, docking time, complication, and conversion rates were successfully reduced. CONCLUSION: We demonstrate progressing safety and efficiency for robotic-assisted radical prostatectomy with the Senhance Surgical System.

Robotic cholecystectomy using Senhance robotic platform versus laparoscopic conventional cholecystectomy: a propensity score analysis.

INTRODUCTION: Our study objective was to evaluate differences in intraoperative and postoperative outcomes of robotic cholecystectomy (RC) using Senhance robotic platform vs laparoscopic cholecystectomy (LC). MATERIAL AND METHODS: A retrospective case - matched analysis was performed for all patients who underwent cholecystectomy from November 2018 to November 2019. RC cases were matched to LC. RC was performed using Senhance robotic platform. Propensity score matching analysis with a ratio of 1:1 (RC: LC) was performed. The groups were matched according to age, sex, body mass index (BMI). All procedures were performed by two same experienced robotic surgeons at Klaipeda University Hospital (O.D. and V.E.). Age, BMI, operative time, blood loss and length of hospital stay were collected and analysed between those patient groups. RESULTS: A total of 40 patients underwent RC or LC. There were no statistical differences between groups in concern of length of hospital stay, blood loss or complications. There were no bile duct injuries in either group, no intraoperative complications, no conversions either RC to LC or LC to open surgery. One patient in robotic group was reoperated on postoperative day 5 regarding sub-hepatic haematoma. The only statistical significance was in operative time (p < .05) which was longer in RC group. Median docking time was 12 min (range 5-23). CONCLUSIONS: Robotic cholecystectomy using Senhance robotic platform appears to be safe in comparison with laparoscopic cholecystectomy. Laparoscopic cholecystectomy might be feasible in gaining robotic surgery skills.
