Addressing parastomal herniation through biomechanical simulation.

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
purposeParastomal hernia remains a significant source of post-operative morbidity. Existing surgical solutions have shown limited success while not addressing the biomechanics underpinning parastomal herniation. The primary objective was to examine the influence of stoma aperture shape on abdominal wall stress and tissue destruction. The secondary objective compared mesh designs with respect to abdominal wall stress.
methodsFinite element analysis of an abdominal wall model was used to simulate various stoma and mesh designs. The outcome measures were abdominal wall (mmHg) pressure required to initiate tissue tearing, stress distribution and median and peak abdominal wall stress (N/m
resultsThe simulation demonstrated that the cruciate stoma incision developed high stress concentration at the apices of the slit incisions. The circular stoma incision distributed stress uniformly. The circular stoma design was more resistant to tissue tearing. The Keyhole mesh design demonstrated the lowest median and peak stress at 17.32 and 28.01 N/m
conclusionsThis study has demonstrated that the shape of the fascia incision and mesh design have a significant impact on parastomal hernia formation. Novel designs can be used to optimise the stoma. The circular stoma and loose mesh designs are promising avenues for future research.
