Risk of reoperation after TEP, TAPP, and Lichtenstein repair for primary groin hernia: a register-based cohort study across two nations

Our study demonstrated low rates of reoperation for recurrence after Lichtenstein, TEP, and TAPP repairs. In men, TEP repair is associated with an increased risk of reoperation for recurrence compared with Lichtenstein and TAPP repair. For females, the laparoscopic approaches were superior to the Lichtenstein repair. These findings emphasize the importance of international comparative studies to optimize hernia management strategies.
