When tissue damage is substantial or the original architecture cannot be regenerated, the body initiates a repair process that results in the formation of a scar. This process involves fibroblasts producing collagen to create a dense, fibrous framework.12
Scar tissue can distort or obstruct an organ through the following mechanisms:
- Contraction and Distortion: The volume of a mature scar is typically less than the original tissue it replaces. As the scar matures, it can contract, causing the surrounding organ to shrink or become physically distorted.12
- Obstruction: In tubular structures, such as the intestines, the formation of scar tissue can lead to narrowing. This reduction in the diameter of the lumen can result in a partial or complete obstruction of the organ.1
- Loss of Function: If scar formation is excessive, it often leads to a significant loss of function in the affected area. Furthermore, because scar tissue does not replicate the complex architecture of original healthy tissue, the newly formed area may lack the necessary orientation to blood vessels or ducts required for proper physiological function.12
