Two open preperitoneal hernia repairs were compared in this study that included 800 procedures. Chronic pain rates were low, and comparable after one year in each group. Recurrence was higher after the trans-rectal approach compared to the trans-inguinal approach (8.9 versus 4.6 per cent; P=0.022), but the difference was reduced when the learning curve for the procedure was taken into account.
