Purpose The objective of this study was to assess data on inguinal hernia repairs (IHR) performed for recurrence over a 16 year period (2004—2019) in Spain. Methods A retrospective cohort study of 1,302,788 patients who underwent IHR from January 2004 to December 2019 was conducted. Data were extracted from the Spanish Minimum Basic Data Set (MBDS) of the Health Ministry database. The primary objective was to analyse the proportion of IHR performed by recurrence. As secondary objectives, we evaluated factors related to recurrent hernia (analysed by univariate analysis and multivariable logistic regression analysis) and trends in the recurrent case rate over the 16 year period. Results We identified 95,025 patients (7.3% of all IHR) who underwent surgery for recurrent inguinal hernia. Patients undergoing recurrent IHR were more likely to be male (OR 1.687, 95% CI 1.645–1.730), elderly (age > 74 years), and more complicated when they arrived in the operating room (gangrene OR 3.951, 95% CI 3.734–4.180; occlusion OR 1.905, 95% CI 1.853–1.960), and thus had more surgical site occurrences and related mortality. The proportion of IHR performed for recurrence has been dropping over the years (8.7% in 2004 vs. 6.5% in 2019, p
