Introduction:
The aim of this study was to investigate reoperation for recurrence in men and women with respect to method of repair, hernia anatomy and year of operation.
Method:
Since 1992, groin hernia repairs performed in Sweden are prospectively registered in the Swedish Hernia Register, (SHR). Reoperations are noted, regardless of where the reoperation is performed. Risk of reoperation for recurrence is calculated for men and women with respect of method of repair, hernia anatomy and year of operation.
Results:
Out of 221 108 eligible operations registered between 1992-2013, 17 545 (8%) were performed on women. The risk of being operated for recurrence after laparoscopic surgery was lowered in women, RR 0,4(95%CI 0.3-0.7) and increased in men, RR 2.3(95% CI 2.0-2.7), compared to the Lichtenstein technique.
Discussion:
The reoperation for recurrence rate differed significantly between men and women. As regards the technique used for primary repair, laparoscopic groin hernia repair lowered the risk of reoperation for recurrence in women whereas it doubled the risk in men.
