Is previous radical prostatectomy a contraindication to minimally invasive inguinal hernia repair? A contemporary meta-analysis

Traditionally, radical prostatectomy (RP) has been considered a contraindication to minimally invasive inguinal hernia repair. Purpose of this systematic review was to examine the current evidence and outcomes of minimally invasive inguinal hernia repair after RP.

Web of Science, PubMed, and EMBASE data sets were consulted. Laparoscopic transabdominal preperitoneal repair (TAPP), robotic TAPP (r-TAPP), and totally extraperitoneal (TEP) repair were included.

Overall, 4655 patients (16 studies) undergoing TAPP, r-TAPP, and TEP inguinal hernia repair after RP were included. The age of the patients ranged from 35 to 85 years. Open (49.1%), laparoscopic (7.4%), and robotic (43.5%) RP were described. Primary unilateral hernia repair was detailed in 96.3% of patients while 2.8% of patients were operated for recurrence. The pooled prevalence of intraoperative complication was 0.7% (95% CI 0.2–3.4%). Bladder injury and epigastric vessels bleeding were reported. The pooled prevalence of conversion to open was 0.8% (95% CI 0.3–1.7%). The estimated pooled prevalence of seroma, hematoma, and surgical site infection was 3.2% (95% CI 1.9–5.9%), 1.7% (95% CI 0.9–3.1%), and 0.3% (95% CI = 0.1–0.9%), respectively. The median follow-up was 18 months (range 8–48). The pooled prevalence of hernia recurrence and chronic pain were 1.1% (95% CI 0.1–3.1%) and 1.9% (95% CI 0.9–4.1%), respectively.

Minimally invasive inguinal hernia repair seems feasible, safe, and effective for the treatment of inguinal hernia after RP. Prostatectomy should not be necessarily considered a contraindication to minimally invasive inguinal hernia repair.
