Background: The aim was to assess chronic pain after two Lichtenstein repairs for inguinal hernias (Lichtenstein-Lichtenstein) compared with Lichtenstein followed by a laparoscopic reoperation (Lichtenstein-Laparoscopy). Methods: In this cohort study, adults having an inguinal hernia reoperation were identified in a nationwide database. Lichtenstein-Lichtenstein was matched 1:3 with Lichtenstein-Laparoscopy and sent validated pain questionnaires. The primary outcome was difference in proportion of patients with chronic pain-related functional impairment. Secondary outcomes were differences in chronic pain prevalence and severity. Results: In total, 196 patients having Lichtenstein-Lichtenstein and 777 patients having Lichtenstein-Laparoscopy were included. There was no difference in the primary outcome, 26% with pain in Lichtenstein-Lichtenstein versus 19% in Lichtenstein-Laparoscopy (p = 0.051). However, a few of the secondary outcomes favored Lichtenstein-Laparoscopy. Conclusions: A high proportion of patients in both groups had pain several years after the second repair. None of the analyses favored Lichtenstein-Lichtenstein, but a few of the secondary outcomes favored Lichtenstein-Laparoscopy.
