The study attempts to quantify the relative risks for recurrence depending on complex combinations of plausible risk factors, in particular mesh, mesh fixation, hernia size and hernia type. For this purpose the investigators will analyze data from the Swedish Hernia Registry (SHR).

This is an open cohort study design where the investigators will analyze existing data that have been prospectively collected in the Swedish Hernia Registry (SHR), which covers \> 95% of all groin hernia repairs in Sweden. The very large cohort of more than 38,000 TEP (totally extraperitoneal) and TAPP (transabdominal preperitoneal) repairs enables assessment of the relative risks for recurrence depending on complex combinations of plausible risk factors, in particular mesh, mesh fixation, hernia size and hernia type, with fulfilling statistical power. Each participant was entered at the date of surgery, when demographic and intraoperative data were registered. Reoperations were registered in the SHR in the same manner as index repairs, and were used as endpoints.
