Diaphragmatic overlay reconstruction using a bovine pericardial patch (Peri-Guard®): feasibility, safety, and radiographic outcomes.
Article in General thoracic and cardiovascular surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSurgical treatment of symptomatic diaphragmatic paralysis or eventration classically relies on suture plication of the elevated hemidiaphragm. We describe an alternative technique-overlay reconstruction of the diaphragm using a bovine pericardial patch (Peri-Guard®) without formal plication sutures-and report its feasibility, safety, and radiographic outcomes.
methodsWe retrospectively reviewed consecutive patients undergoing diaphragmatic overlay reconstruction with a Peri-Guard® patch at Hannover Medical School between January 2020 and May 2025. Demographic, perioperative, and radiographic data were collected. Diaphragmatic elevation was quantified on chest radiographs using the interdiaphragmatic height difference (IHD) and relative IHD (rIHD). Preoperative and postoperative measurements were compared.
resultsThirteen patients underwent patch-based diaphragmatic overlay reconstruction. Mean age was 60.0 ± 9.3 years, and mean body mass index was 29.4 ± 4.9 kg/m
conclusionsIn this small retrospective series, patch-based diaphragmatic overlay reconstruction was technically feasible and was associated with marked early radiographic correction of diaphragmatic elevation. Comparative studies against conventional suture plication are needed to determine relative durability and functional benefit.
