Abstract

Objective: To compare the occurrence of graft‐related complications (GRC s) and biomechanical properties of meshes implanted vaginally and abdominally. Design: In vivo animal experiment. Setting: Centre for S urgical T echnologies, M edical F aculty, KU Leuven, B elgium. Population: Twenty adult parous T exel ewes. Methods: Sheep were implanted with G ynemesh M, a 28‐g/m² polypropylene mesh reinforced with polyglecaprone fibres, under general anaesthesia. Dissection into the rectovaginal septum was performed to accommodate a flat 50 × 50 mm (n = 10) or 35 × 35 mm (n = 10) mesh, which was sutured to the underlying tissues. A 50 × 50 mm mesh was laid over a primarily sutured, full‐thickness, 40‐mm longitudinal abdominal wall incision. Sacrifice was at 60 days (n = 10) or 90 days (n = 5). Main outcome measures: The occurrence of exposure, the degree of contraction and examination of the biomechanical properties of explants with a minimum radius of 32 mm via biaxial tensiometry. Results: Insertion of a 50 × 50 mm mesh led to exposures in 30% (3/10) of cases, and the average contraction rate was 52 ± 14%. In the 35 × 35 mm implants, there were no exposures, and the contraction rate was 25 ± 26.3%. Vaginal explants with no GRC s and of sufficient size had biomechanical properties that were comparable with those of abdominal explants. Conclusion: Vaginal mesh insertion is associated with GRC s, such as exposure and contraction. Although other factors probably play a role, this study illustrates that mesh size may also induce these complications. In a vaginal surgery model, clinically occurring GRC s can be reproduced. In addition, biomechanics of uncomplicated vaginal explants are comparable with those measured on abdominal explants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
