Pain with sexual activity at 1 and 3 years: Comparing total extraperitoneal with Lichtenstein inguinal hernia repair in a randomized setting (TEPLICH trial).

BACKGROUND: Pain at sexual activity induced by an inguinal hernia or as a cause of its repair is not thoroughly studied. Reported frequencies are between 25% and 30% preoperatively and 10% and 15% postoperatively. The primary aim was to analyze pain at sexual activity at 1 year comparing total extraperitoneal with Lichtenstein repair in a randomized setting. METHODS: Men, 30 to 60 years old, with a primary inguinal hernia were randomized to total extraperitoneal without mesh fixation or Lichtenstein repair. A questionnaire on pain prevalence, frequency, intensity, and impairment of sexual functions caused by pain at sexual activity was introduced. Clinical examination, a questionnaire on sexual function, and the 36-Item Short Form Survey were performed preoperatively and at 1 and 3 years postoperatively. A risk factor analysis for pain at sexual activity as performed. RESULTS: A total of 243 patients (111 total extraperitoneal and 132 Lichtenstein) were included between 2008 and 2014; 97% remained for 1-year and 90% for 3-year analysis. Preoperative pain at sexual activity was reported in 35%, with a reduction to 5.9% in total extraperitoneal and 12.5% in Lichtenstein (P = .098) at 1 year and 7.0% in total extraperitoneal and 9.3% in Lichtenstein (P = .566) at 3 years. Quality of life preoperatively was markedly reduced in patients with pain at sexual activity but restored almost to norm levels at 1 and 3 years. New pain at sexual activity (harm) was seen in 8 patients (3.6%) at 1 year. Risk factors for having postoperative pain at sexual activity were preoperative pain and Lichtenstein technique. CONCLUSION: Pain at sexual activity in inguinal hernia patients is more common than suspected and reduces quality of life. Repair will markedly reduce pain at sexual activity and restore quality of life in most patients without difference between techniques. Patients should be informed on a potential relation between having an inguinal hernia and sexual impairment.
