Real-World Data on the Effectiveness of Microporous Polysaccharide Hemospheres for Allowing Even Novice Surgeons to Perform Robot-Assisted Radical Prostatectomy Safely.

OBJECTIVE

Radical prostatectomy can be performed more safely and with fewer com- plications since the advent of robot-assisted surgery. However, increased bleeding is a concern when robot-assisted radical prostatectomy includes lymph node dissection and nerve sparing. In real-world clinical practice, inexperienced surgeons sometimes perform robot-assisted radical prostatectomy. In this study, we investigated the effec- tiveness of microporous polysaccharide hemospheres as a local hemostatic agent in robot-assisted radical prostatectomy.

METHODS

We retrospectively evaluated 301 patients who underwent robot-assisted radical prostatectomy at our institution between December 2017 and November 2020. The patients were divided into 2 groups according to whether their surgery was per- formed after the introduction of microporous polysaccharide hemospheres as a local hemostatic agent (group A, n = 140) or before it (group B, n = 161: historical control).

RESULTS

Preoperative androgen deprivation therapy was significantly more common in group A than in group B (23 vs. 11, P = .009). Furthermore, surgeons were significantly less experienced (P < .001) and the operation time was significantly longer (260 min- utes vs. 229 minutes; P < .001) in group A than in group B. There was no significant difference in any other patient background characteristics or in the surgical outcomes between the groups.

CONCLUSION

The use of microporous polysaccharide hemospheres allowed even inex- perienced surgeons to perform robot-assisted radical prostatectomy without compro- mising surgical outcomes.
