Abstract
Wound dehiscence after laparotomy remains a severe and potentially life-threatening complication, particularly in critically ill patients exposed to increased intra-abdominal pressure, mechanical ventilation, and repetitive mechanical stress. Traditionally, fascial failure has been attributed primarily to impaired biological healing; however, this perspective does not fully explain the dynamic mechanical environment of the abdominal wall in the postoperative period. This review proposes a unified mechanical and geometric framework for understanding fascial failure after laparotomy. It emphasizes that successful closure depends not only on tissue quality but also on the distribution of forces and the geometry of the fascial defect. Intraoperative techniques such as progressive suturing and central force redistribution partially address this problem by modifying defect geometry and reducing peak tension. However, these strategies do not extend into the postoperative phase, where critically ill patients are exposed to repeated dynamic loading. This mismatch between tissue strength and mechanical stress may lead to progressive suture failure and wound dehiscence. Understanding fascial closure as a dynamic system influenced by both mechanical forces and geometric configuration may provide new insights into the prevention of postoperative complications and guide the development of future therapeutic strategies.
