Which suture is absorbable?

Plain catgut is the correct answer as it is a natural absorbable suture material made from the intestinal mucosa of sheep or goats. This type of suture is designed to be broken down by the body over time, eliminating the need for removal after the healing process. It is commonly used in various surgical procedures due to its tissue compatibility and ability to absorb moisture, which helps accelerate its degradation.

In contrast, silk and nylon are examples of non-absorbable sutures. Silk, although it is often used for suturing soft tissues due to its excellent handling properties, does not get absorbed and must be removed after the tissue has healed. Nylon is a synthetic non-absorbable suture known for its strength and elasticity, often utilized for closure of skin incisions or lacerations, but like silk, it remains permanently in the body unless removed.

Polyester fiber is also a non-absorbable material used for sutures. It provides great tensile strength and is often chosen for its durability in areas that require long-term support. However, it too does not dissolve in the body.

Thus, the nature of plain catgut makes it uniquely suited for applications where temporary support is needed as the underlying tissue heals, distinguishing it from
