Design outcomes

Primary

Measure	Time frame
Proportion of patients with mesh infection after inguinal hernia repair who required mesh removal during the treatment course.	—

Secondary

Measure	Time frame
Incidence of mesh infection during the study period Interval from initial hernia repair to diagnosis of mesh infection Causative microorganisms Differences in outcomes between total mesh removal and partial mesh removal, including postoperative complication rates and infection recurrence Time to clinical cure of mesh infection Hernia recurrence rate and recurrence pattern after mesh removal All secondary outcomes will be assessed up to the last follow-up.	—
