Which type of absorbable suture is often used for delicate tissue closure?

Vicryl is a synthetic absorbable suture made from a copolymer of glycolic acid and lactide. It is widely used in surgery because it has favorable handling characteristics and provides excellent tissue apposition. Vicryl is particularly suitable for delicate tissue closure, such as in ophthalmic surgeries, because it has minimal tissue reactivity and a predictable absorption rate.

The unique braided structure of Vicryl allows it to maintain its strength for a sufficient period while allowing for tissue healing, making it ideal for areas where tension is a concern and where the delicate nature of the tissue could be easily compromised by stronger, non-absorbable sutures. Its absorption occurs over a period of four to six weeks, providing ample time for the tissue to heal before the suture is fully absorbed.

Other suture materials, like plain gut or PDS, while also absorbable, may not be as suitable for delicate tissue. Plain gut is made from collagen and can have variable absorption properties, which might be less ideal for intricate closures. PDS, although strong and with a longer absorption timeline, is also less flexible, making it less suitable for very delicate tissues compared to Vicryl. Silk, on the other hand, is a non-absorbable suture
