Dual Tack Mesh Fixation System on a Cadaveric Porcine Model-Creation of a Mesh Fixation System for Hernia Treatment and Prevention.

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
backgroundOnlay mesh repair (OMR) has proven to be a widely used, simple, and effective technique for treatment and prevention of hernia occurrence. Despite established benefits, there is still a lack of widespread adoption. In this study, we present the Dual Tacker Device (DTD), an enabling technology that directly addresses the limitations to the adoption of OMR, saving surgical time and effort and making OMR more reproducible across a wide range of patients.
methodsThe DTD mesh fixation system is a semiautomated, hand-held, disposable, multipoint onlay mechanical mesh fixation system that is able to rapidly and uniformly tension and fixate mesh for both hernia treatment and prevention. A cadaveric porcine model was used as a pilot test conducted during a 2 day session to assess the usability of the device and to show that the DTD provided equivalent or superior biomechanical support compared with the standard of care (hand-sewn, OptiFix).
resultsOur study included 37 cadaveric porcine incisional closure abdominal wall models. These were divided into four groups: DTD-mediated OMR (n = 14), hand-sewn OMR (n = 7), OptiFix OMR (n = 9), and suture-only repair (no mesh) (n = 7). Eight surgical residents performed device-mediated and hand-sewn OMR. Average time to completion was fastest in the DTD cohort (45.6s) with a statistically significant difference compared with the hand-sewn cohort (343.1s, P < 0.01). No difference in tensile strength was noted between DTD (195.32N), hand-sewn (200.48N), and OptiFix (163.23N). Discreet hand movements were smallest in the DTD (29N) and significant (P < 0.01) when compared with hand-sewn (202N) and OptiFix (35N).
conclusionsThe use of the DTD is not only feasible, but demonstrated improvement in time to completion and economy of movement over current standard of care. While more testing is needed and planned, compared with conventional approaches, the DTD represents a robust proof of principle with promising implications for clinical feasibility and adoptability.
