Abstract

Adhesions are the most frequent complication of abdominopelvic surgery, yet the extent of the problem, and its serious consequences, has not been adequately recognized. Adhesions evolved as a life-saving mechanism to limit the spread of intraperitoneal inflammatory conditions. Three different pathophysiological mechanisms can independently trigger adhesion formation. Mesothelial cell injury and loss during operations, tissue hypoxia and inflammation each promotes adhesion formation separately, and potentiate the effect of each other. Studies have repeatedly demonstrated that interruption of a single pathway does not completely prevent adhesion formation. This review summarizes the pathogenesis of adhesion formation and the results of single gene therapy interventions. It explores the promising role of combinatorial gene therapy and vector modifications for the prevention of adhesion formation in order to stimulate new ideas and encourage rapid advancements in this field.

摘要

粘连是腹盆腔手术最常见的并发症,但该问题的严重程度尚未得到充分认识。粘连是作为一种限制腹腔内炎症扩散的救命机制而产生的。有三种不同的病理生理机制可以独立触发粘连形成。手术过程中间皮细胞的损伤和丢失、组织缺氧和炎症都会分别促进粘连形成,并增强彼此的作用。研究反复表明,阻断单一途径并不能完全防止粘连形成。这篇综述总结了粘连形成的发病机制和单一基因治疗干预的结果。它探讨了组合基因治疗和载体修饰在预防粘连形成方面的有前途的作用,以激发新的思路,并鼓励该领域的快速发展。
