Chronic groin pain, discomfort and physical disability after recurrent groin hernia repair: impact of anterior and posterior mesh repair.

Unlabelled: Chronic pain and physical disability are well-known problems after primary groin hernia surgery, but the outcome after recurrent hernia surgery is much less known.

Purpose: To study the impact of anterior mesh repair (AMR) and posterior mesh repair (PMR) on chronic pain and disability after first recurrent groin hernia surgery in a population-based cohort derived from the Swedish Hernia Register.

Methods: Consecutive unilateral, first and second recurrent hernia repairs, registered between 1998 and 2007, were included. Follow-up was performed in 2009 based on the Inguinal Pain Questionnaire (IPQ) and selective clinical examination, comparing prevalence of pain between AMR, endoscopic (E-PMR) and open posterior mesh repairs (O-PMR) after first recurrent repair. Chronic pain after a second recurrent repair was analysed.

Results: Altogether 671 first recurrent repairs were analysed: 329 AMRs, 161 E-PMRs and 181 O-PMRs. IPQ response rate was 70.6%. If the index repair was anterior, the E-PMR was associated with a lower risk of chronic pain and disability compared to AMR [OR 0.54 (CI 0.30-0.97), p = 0.039]. The risk of chronic pain increased after a second recurrent repair. A surgeon's annual volume >5 O-PMRs was related to a lower risk compared to ≤5 [OR 0.42 (CI 0.19-0.94), p = 0.034].

Conclusion: Endoscopic repair for first recurrent groin hernia surgery, after an index anterior repair, was associated with less chronic pain, discomfort and disability compared to anterior approach. Chronic pain increased after a second recurrent repair. A high surgeon's volume reduced the risk of chronic pain after open posterior mesh repair.
