V11-11: The Michl technique to reduce the incidence of symptomatic lymphoceles following robot assisted radical prostatectomy.Pathophysiology, surgical procedure, and early results of a randomised trial

Video

INTRODUCTION

Pathopysiological considerations showed that there might be two concurrent causes for lymphoceles. This led to devellopment of a surgical technique to reduce the incidence of symptomatic lymphoceles followig robot assisted radical prostatectomy

METHODS

The surgical technique is schematically described and the procedure is shown in the accompanying video.This is an ongoing randomised trial. In accordance to the ethical approval we performed an interim analysis.Follow Up was done with standarized questionnaires at one week, 6 months, and 12 months

RESULTS

Overall, between June 2017 and July 2018, 543 patients were randomised. 280 were operated according the Michl technique, and 263 had the normal surgery.Clinical, surgical, and pathological parameters were comparable between the two groups. Additionally, we evaluated the results of 1674 nonrandomised patients operated on between September 2016 and July 2018. 95 patients had the Michl technique.

CONCLUSION

Preliminary results showed that the Michl technique achieves more than halving the risk of symptomatic lymphoceles.
