What process leads to the absorption of collagen suture?

The absorption of collagen sutures is primarily facilitated by enzyme digestion. Collagen sutures are made from natural collagen derived from animal tissues, and these sutures undergo enzymatic degradation in the body. The body's immune response and the presence of various enzymes, such as collagenases, play a significant role in this process. These enzymes break down the collagen fibers over time, leading to the gradual loss of the suture's structural integrity until it is fully absorbed by the surrounding tissues.

Other processes, such as hydrolysis or mechanical breakdown, do not accurately describe how collagen sutures are absorbed. While hydrolysis involves the chemical breakdown of compounds due to reaction with water, it is not the primary mechanism for collagen suture absorption. Mechanical breakdown refers to a physical process rather than a biochemical one and is not relevant in the context of how sutures are absorbed. Photolysis, the process by which chemical compounds are broken down by light, is also not associated with the absorption of sutures. Therefore, enzyme digestion is the most accurate and relevant mechanism leading to the absorption of collagen sutures.
