    Abstract:
    BACKGROUND: Long-term clinical outcome after a recurrent inguinal hernia repair may be associated with the type of repair, that is, laparoscopic or open. The results from previous randomised controlled trials are inconclusive regarding the long-term risk of re-recurrence chronic pain. Accordingly, this trial compared laparoscopic transabdominal preperitoneal repair (TAPP) with Lichtenstein's repair. The primary outcome was repair for a re-recurrence. The secondary outcome was chronic pain. METHODS: Multi-centre single-blinded, randomised trial on TAPP vs Lichtenstein's repair in male patients operated for a recurrent inguinal hernia after a primary open inguinal hernia repair. Follow-up for repair for a re-recurrence was registered in the Danish Hernia Database. Prospective follow-up data were achieved by a structured questionnaire on pain-related functional impairment using the Activities Assessment Scale (AAS-pain). RESULT: A total of 360 patients were randomised, 297 were mailed the follow-up questionnaire (63 excluded) after median 12 years (range 9-15). A total of 265 patients responded to the questionnaire (response rate 89%). The cumulative rate of repair for re-recurrence after 12 years was 10% (95% confidence interval (CI) 5.3-15.1%) vs 10% (5.6-14.7%) after TAPP or Lichtenstein, respectively (p = 0.764). Moderate/severe AAS-pain was reported by 4% (95% CI 1-8%) vs 7% (95% CI 3-11%) patients after TAPP or Lichtenstein, respectively (p = 0.698) CONCLUSION: Long-term re-recurrence rate and incidence of chronic pain was surprisingly high respectless of surgical approach and neither TAPP nor Lichtenstein's procedure was superior to improve surgical results.
