PAEA Surgery End Of Rotation (EOR) Practice Exam

Which of the following sutures is classified as non-absorbable?

1. Vicryl

2. Monocryl

3. Silk

4. PDS (polydioxanone)

The correct answer is: Silk

Silk is classified as a non-absorbable suture, which makes it suitable for applications where long-term tissue support is required. Non-absorbable sutures are typically used in situations where it is important for the suture to maintain its strength and integrity for an extended period, such as in skin closures, some types of vascular surgeries, and in areas where high tension is expected. Silk sutures are made from natural fibers and are known for their ease of use and excellent handling properties. They have a lower tissue reactivity compared to some other materials and provide a reliable option for wound closure that is intended to remain in place for an extended duration, pending the healing of the tissue. In contrast, Vicryl and Monocryl are absorbable sutures. Vicryl is a braided polyglactin suture that loses its tensile strength over time as it is gradually absorbed by the body. Monocryl is a monofilament suture made from poliglecaprone and is also absorbable, breaking down relatively quickly compared to Vicryl. PDS, while designed for longer absorption times, is also considered an absorbable suture. Therefore, silk stands out as the non-absorbable option among the sut
