Long term efficacy of prosthetic inguinal herniorrhaphy concomitant with robot-assisted laparoscopic radical prostatectomy.

Purpose: Patients who undergo robot-assisted laparoscopic radical prostatectomy (RARP) may present concurrent or secondary inguinal hernia (IH). Surgical repair of IH simultaneously with RARP has been reported. We aimed to assess the long-term efficacy of concurrent prosthetic IH repair with RARP. Methods: Data for consecutive patients undergoing concurrent IH repair with RARP for localized prostate cancer at our institution between 2006 and 2017 were retrospectively analysed. Patients were matched based on age, BMI, and year of surgery, with patients undergoing RARP alone. IH repair was performed with a polyester mesh. Efficacy of IH repair was the primary outcome. Patient characteristics, perioperative data, recurrence and treatment were recorded. Results: A total of 136 men were included, 50% treated by RARP and concurrent IH, 50% by RARP alone. Mean age was 65 years (SD 6) and mean BMI 26.8 (SD 2.5). IH was diagnosed preoperatively in 42 patients (62%) or intraoperatively in 26 patients (38%). A total 18 patients (26%) had bilateral hernias and 50 patients had unilateral hernias (right 31%, left 43%). There was no significant difference between the two groups regarding perioperative data. The herniorrhaphy added 34 min to the operative time (p < 0.001). After a mean follow-up of 106 months [SD 38], 9 patients (13%) presented recurrence of IH, with a mean time to recurrence of 43 months [SD 35]. Age was significantly associated with IH recurrence (p = 0.0007). Conclusion: Concomitant IH repair and RARP appear to be a safe procedure with good long-term safety and efficacy, without significantly increasing morbidity. [ABSTRACT FROM AUTHOR]
