Purpose:
Surgery for groin hernia is one of the most common operations in the world. Therefore, research concerning the outcomes of groin hernia surgery is extremely important both for the individual patient as well as for those providing the healthcare funding. The aim of this study is to evaluate the outcomes of hernia surgery in Sweden over a 30 year time period, from 1992 to 2021.
Methods:
All groin hernia repairs in the Swedish Hernia Register between 1992 to 2021 were analyzed with emphasis on the surgical method, reoperation rate for recurrence and date of surgery, specifically 1992-2001, 2002-2011 and 2012-2021. By using personal identification numbers, a cumulative reoperation rate has been deduced for males and females separately.
Results:
A total of 368,502 groin hernia operations identified in the Swedish Hernia Register between 1992 to 2021 were eligible for analysis. Since the register was begun, there have been significant changes in the choice of operative techniques, from suture repair in 1992 to open anterior mesh repair around the year 2000, until today, where an increasing proportion of hernias are repaired using laparo-endoscopic techniques. There has been a reduction in the reoperation rate for recurrence in both males and females, with the most pronounced improvement being seen in females. The laparo-endoscopic technique is associated with a reduced incidence of reoperation for recurrence in females.
Conclusion:
Groin hernia surgery in Sweden has undergone substantial changes over the past 30 years. Reoperation for recurrence has decreased significantly during recent years, especially in females.
