Suture with least adhesion to tissues and high plasticity is:
**Core Concept**
The question is testing the properties of different sutures, specifically their tendency to cause tissue adhesions and their plasticity. Sutures with low adhesion and high plasticity are desirable for certain surgical procedures, as they reduce the risk of complications and promote healing.
**Why the Correct Answer is Right**
The correct answer is a monofilament suture, such as nylon or polypropylene. These sutures have a smooth, non-absorbable surface that minimizes tissue reaction and adhesion. Their high plasticity allows them to stretch and move with the tissue, reducing the risk of knot failure and promoting wound healing.
*Option A:* This option is incorrect because braided sutures, such as Vicryl, have a higher tendency to cause tissue adhesions due to their absorbable nature and woven structure.
*Option B:* This option is incorrect because chromic catgut sutures are highly absorbable and tend to cause more tissue reaction and adhesion compared to monofilament sutures.
*Option C:* This option is incorrect because silk sutures have a high tendency to cause tissue adhesions due to their absorbable nature and rough surface.
**Clinical Pearl / High-Yield Fact**
When choosing a suture, consider the type of tissue, the location of the wound, and the desired outcome. Monofilament sutures like nylon or polypropylene are ideal for areas with high tension, such as the skin or tendons, while braided sutures like Vicryl are better suited for areas with low tension, such as the bowel or omentum.
**Correct Answer:** C. Polypropylene
