Hernia, Inguinal, Chronic Pain
Conditions
Brief summary
The objective of this study is to evaluate chronic pain and sexual dysfunction after inguinal hernia repair involving mesh fixation with sutures (Lichtenstein) compared with no mesh fixation (Onstep). The study hypothesis is that a smaller proportions of patients operated without mesh fixation (Onstep) will have chronic pain that impairs daily function.
