A retrospective review of all inguinal hernia repairs performed on adult residents of Olmsted County, MN, from 1989 to 2008 was performed through the Rochester Epidemiology Project.
A total of 4,433 inguinal hernia repairs among 3,489 individuals were reviewed. Non-mesh-based repairs predominated in the late 1980s (94%in 1989), declined throughout the 1990s (40%in 1996), and are rarely used nowadays (4%in 2008). Open mesh-based repairs comprised 21%in 1990, peaked in 2001 with 72%, and declined to 55%in 2008. The adoption of laparoscopic repairs began in 1992 (6%) and has increased steadily to 41%in 2008 (P < .001).
Although non-mesh-based repairs, once the predominant method, have been supplanted by open mesh-based techniques, nowadays the use of laparoscopic inguinal hernia repair techniques has increased substantially to nearly equal that of open mesh-based techniques.
