Risk of reoperation after TEP, TAPP, and Lichtenstein repair for primary groin hernia: a register-based cohort study across two nations.
Observational study in Hernia : the journal of hernias and abdominal wall surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeAnnually, more than 24,000 groin hernia repairs are performed in Sweden and Denmark, approximately 12,000 of which are laparoscopic like totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) repairs. TEP is the preferred technique in Sweden, whereas TAPP is preferred in Denmark. This study aimed to assess the risk of reoperation for recurrence following TAPP, TEP, and Lichtenstein techniques.
methodProspectively collected data from the Danish Hernia Database and the Swedish Hernia Register were utilized for this observational register-based study. Primary groin hernia repairs utilizing TEP, TAPP, or Lichtenstein techniques between 2004 and 2020 were included. The primary outcome was the reoperation rate for recurrence analyzed using both crude reoperation rates and Cox proportional hazard regression analysis.
resultsDuring 17 years, 347,912 primary groin hernia repairs were performed, of which 12% were TEP, 15% TAPP, and 74% Lichtenstein repairs. In males, the risk of reoperation was higher after TEP than after TAPP (HR 1.38, 95% CI 1.27-1.5) and Lichtenstein (HR 1.44, 95% CI 1.36-1.53). In females, Lichtenstein repair had a higher risk than the laparoscopic approaches, with no significant difference between TAPP and TEP.
conclusionOur 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.
