Abstract

This study aimed to compare the tissue damage caused by barbed sutures and conventional sutures using scanning electron microscopy (SEM). Porcine myocardium was incised and sutured using different thread types: barbed suture, (STRATAFIX^® Spiral PDS PLUS) and conventional sutures, (VICRYL^® and PDS Plus^®). Needle hole shapes were examined at magnifications of 30×-100×. VICRYL^® suture damaged the tissue and created large gaps around the needle holes. The tissue around the needle holes was smoother and less damaged in the single suture ligations with PDS^®; however, a large gap had formed. In the continuous suture with STRATAFIX^®, the tissue around the needle holes was significantly smoother and minimally damaged, with no noticeable gaps around the needle holes. Barbed sutures reduced the load on needle holes and minimised tissue damage owing to the dispersion of traction forces by the barbs compared with conventional sutures.

使用扫描电子显微镜观察动物实验室模型中倒刺缝合线和传统缝合线对组织的损伤。

本研究旨在利用扫描电子显微镜（SEM）比较倒钩缝合线和传统缝合线对组织造成的损伤。对猪心肌进行切口，并使用不同类型的线进行缝合：倒钩缝合线（STRATAFIX® Spiral PDS PLUS）和传统缝合线（VICRYL® 和 PDS Plus®）。针孔形状在 30×-100× 倍放大镜下观察。VICRYL® 缝合线损伤了组织，并在针孔周围形成了较大的缝隙。在使用 PDS® 进行单次缝合结扎时，针孔周围的组织较为光滑，受损程度也较低，但仍形成了较大的缝隙。在使用 STRATAFIX® 进行连续缝合时，针孔周围的组织明显更加光滑，受损程度也很小，针孔周围没有明显的缝隙。与传统缝合线相比，倒钩缝合线由于分散了牵引力，从而减轻了针孔的负荷，并将组织损伤降至最低。

期刊介绍： Journal of Obstetrics and Gynaecology represents an established forum for the entire field of obstetrics and gynaecology, publishing a broad range of original, peer-reviewed papers, from scientific and clinical research to reviews relevant to practice. It also includes occasional supplements on clinical symposia. The journal is read widely by trainees in our specialty and we acknowledge a major role in education in Obstetrics and Gynaecology. Past and present editors have recognized the difficulties that junior doctors encounter in achieving their first publications and spend time advising authors during their initial attempts at submission. The journal continues to attract a world-wide readership thanks to the emphasis on practical applicability and its excellent record of drawing on an international base of authors.
