Peri-Operative Outcomes after Open and Robot-Assisted Radical Cystectomy by Using an Advanced Bipolar Seal and Cut Technology (Caiman?): A Prospective, Comparative, and Multi-Institutional Study

摘要

Objective: To report and compare the peri-operative outcomes of patients undergoing open (ORC) and robotic-assisted radical cystectomy (RARC) for bladder cancer performed with a radiofrequency seal and cut device (Caiman?). Materials and Methods: Data of patients undergoing ORC or RARC between January 2015 and March 2016 at 6 Italian institutions were prospectively recorded and analyzed. Thirty-and 90-day complications were stratified according to the Martin's criteria and graded according to the Clavien-Dindo classification. Data on operative time, blood loss, transfusion rate, complications, and length of stay were evaluated and compared between the ORC and RARC groups. Results: Thirty-three (66%) and 17 (34%) patients were treated with ORC and RARC, respectively. The median age was 72 (64-78) years. Overall operative time was longer in RARC compared to ORC (389 ± 80.1 vs. 242 ± 62.2 min, p Conclusion: Open and robot-assisted procedures were safely performed by using a new advanced bipolar seal and cut technology (Caiman?). RARC demonstrated to be superior to ORC in terms of bleeding, transfusion rates and length of hospital stay, despite longer operative time.
