Impact of previous inguinal hernia repair on transperitoneal robotic prostatectomy.

OBJECTIVE
Several investigators have noted that previous inguinal hernia repair with or without the use of prosthetic mesh might be a relative contraindication for open or laparoscopic radical prostatectomy due to the presence of adhesions and the difficulty of tissue dissection. We aimed to evaluate the impact of previous hernia repair on the performance and feasibility of robotic prostatectomy.


MATERIALS AND METHODS
We performed a retrospective analysis of 354 patients who underwent robotic prostatectomy at our institution. The three patient groups were: 292 patients who had no prior hernia repair (group 1), 50 patients who had prior inguinal herniorrhaphy without the use of prosthetic mesh (group 2), and 12 patients who had prior inguinal herniorrhaphy with the use of prosthetic mesh. We compared operative time (surgeon console time), estimated blood loss, and operative complications (bladder, bowel, and/or vascular injuries) in the three groups.


RESULTS
Patients with no prior herniorrhaphy (group 1), prior herniorrhaphy without mesh (group 2), and prior herniorrhaphy with mesh (group 3), had similar mean operating times (126.9 minutes, 129.3 minutes and 145.6 minutes, respectively) and similar mean estimated blood loss (152.5 ml, 140.6 ml, and 141.6 ml, respectively) during radical prostatectomy. However, compared to the group of patients who had no prior hernia repair, the group who had prior herniorrhaphy with the use of mesh had a significantly longer mean console operating time (145.6 versus 126.9 minutes, p = .012).


CONCLUSION
Previous hernia surgery, with or without the use of prosthetic mesh, did not represent a significant barrier to the performance of transperitoneal robotic prostatectomy.
