Trends in Australian inguinal hernia repair rates: a 15‐year population study

BACKGROUND An inguinal hernia is one of the most common surgical pathologies, and therefore the repair of an inguinal hernia is one of the most common general surgical procedures. The aim of this study was to assess the trend in inguinal hernia repair (IHR) rates in Australia between 2000/2001 and 2014/2015 using population data from public and private hospitals. METHODS ICD-10 data cubes from the Australian Institute of Health and Welfare were analysed to determine the number of inguinal hernia repairs performed, open or laparoscopically, between 2000/2001 and 2014/2015 financial years. These data were combined with the Australian Bureau of Statistics population data estimates for the corresponding years, to give a procedure per 100 000 estimates. RESULTS Incidence of IHRs within Australia decreased from 217 to 194 per 100 000 population over the 15-year study period. There was a clear shift towards increased uptake of laparoscopic surgery with a subsequent fall in rates of open IHRs. Males accounted for the majority of IHR procedures. Unilateral repair was more common; however, the incidence of unilateral repair rates decreased while bilateral IHR rates increased over the study period. CONCLUSION Laparoscopic techniques are increasingly being used within public and private institutions across the country for inguinal hernia repair. There has also been a decrease in the incidence of IHR procedures performed per year over the 15-year period studied, consistent with published literature from Europe and the USA.
