Laparoscopic radical prostatectomy: transperitoneal versus retroperitoneal approach: is there an advantage for the patient?

PURPOSE OF REVIEW

Radical prostatectomy is the standard treatment for localized prostate cancer; its translation to a laparoscopic approach is considered today not only as feasible and reproducible but also as a valid and teachable alternative to its open counterpart. Beyond the "classical" transperitoneal antegrade route codified by the Montsouris group, several extraperitoneal approaches were developed, claiming clinical equivalence and reduced risks of morbidity and operative times. This article summarizes various aspects of different approaches and their outcome.

RECENT FINDINGS

Complications reported about transperitoneal procedures definitely further the discovery or learning curves of the pioneering teams; the groups who developed extraperitoneal alternatives established their "new approaches" on a solid base of technical skills, acquired transperitoneally. Beyond the unsurpassed qualities of visual and working spaces belonging to the transperitoneal route, which should be taken into account with respect to teaching, transperitoneal antegrade approach to the prostate enables the surgeon with early hemostatic control and essential tactical choices to achieve negative surgical margins.

SUMMARY

So far, as oncological and functional results of both approaches seem equivalent, both approaches should be further developed and remain available for teaching purposes. The true benefit for patients lies more in global quality control of surgery than in an obsessional search for alternatives to established techniques that have already stood the proof of time.
