Abstract

Despite significant advancements, prosthetic hernia repair continues to face unacceptably high complication rates. These likely stem from poor biological responses, such as stiff scar tissue leading to mesh shrinkage. To overcome these issues, the Stenting and Shielding (S&S) Hernia System, a newly designed 3D dynamic device, has been developed for dissection-free laparoscopic placement to permanently obliterate hernia defects. Unlike conventional meshes, this device induces a regenerative biological response, promoting viable tissue growth rather than fibrotic plaque formation. In a porcine experimental model, the S&S device demonstrated the development of a great amount of muscle fibers, alongside nervous and vascular structures, within well-perfused connective tissue. Histological analysis of biopsy specimens excised from the experimental animals revealed progressive muscle fiber maturation from early myocyte development in the short term to fully developed muscle bundles in the long term. The enhanced biological response observed with the S&S device suggests a promising shift in hernia repair, potentially reversing the degenerative processes of hernia formation and promoting tissue regeneration. The S&S Hernia System described here can be classified not merely as a conventional hernia implant, but as part of a new category of hernia devices: the dynamic regenerative scaffold.

摘要

尽管取得了重大进展,但人工疝修补术仍然面临着高得令人无法接受的并发症发生率。这些并发症可能源于不良的生物学反应,比如僵硬的瘢痕组织导致补片收缩。为了克服这些问题,一种新设计的3D动态装置——支架与屏蔽(S&S)疝修补系统已被开发出来,用于在无解剖的情况下通过腹腔镜放置,以永久性消除疝缺损。与传统补片不同,该装置可诱导再生生物学反应,促进有活力的组织生长,而非形成纤维化斑块。在猪实验模型中,S&S装置显示在灌注良好的结缔组织内有大量肌肉纤维以及神经和血管结构生长。对从实验动物身上切除的活检标本进行组织学分析发现,肌肉纤维从短期的早期肌细胞发育逐渐成熟为长期的完全发育的肌束。S&S装置所观察到的增强的生物学反应表明疝修补术有望发生转变,有可能扭转疝形成的退行性过程并促进组织再生。这里描述的S&S疝修补系统不仅可以归类为传统的疝植入物,还可归为一类新型疝装置的一部分:动态再生支架。
