Sexual dysfunction between laparoscopic and open inguinal hernia repair: a systematic review and meta-analysis

Sexual dysfunction after inguinal hernia complication is considered rare. However, its consequences impact on quality of life inevitably. Laparoscopic and open inguinal hernia repair may be comparable in terms of recurrent rate, overall complications, and chronic pain. Therefore, its complication is still questionable between these approaches. In this study, we compared sexual dysfunction and related complications between laparoscopic and open inguinal hernia repair.

Systematic review and meta-analysis of randomized controlled trials (RCTs) studies were performed to compare laparoscopic and open inguinal hernia repair. Risk ratio (RR) and 95% confidence intervals (95% CI) were used as pooled effect size measures.

Thirty RCTs (12,022 patients) were included. Overall, 6014 (50.02%) underwent laparoscopic hernia repair, and 6008 (49.98%) underwent open hernia repair. Laparoscopic approach provided non-significance benefit on pain during sexual activity (RR 0.57; 95% CI 0.18, 1.76), Vas deferens injury (RR 0.46; 95% CI 0.13, 1.63), orchitis (RR 0.84; CI 0.61,1.17), scrotal hematoma (RR 0.99; CI 0.62,1.60), and testicular atrophy (RR 0.46; CI 0.17,1.20). Meanwhile, the open inguinal hernia approach seems to perform better for cord seroma complications and testicular pain.

There is no advantage of laparoscopic inguinal hernia repair over an open approach concerning sexual dysfunction. On the contrary, there is an increasing risk of cord seroma after laparoscopic inguinal hernia repair with statistical significance.
