PAEA Surgery End Of Rotation (EOR) Practice Exam

Which type of sutures are known to be absorbable?

1. Nylon and PDS

2. Silk and Prolene

3. Chromic and Monocryl

4. Polyester and Stainless Steel

The correct answer is: Chromic and Monocryl

The correct answer identifies chromic and Monocryl sutures as absorbable materials. Absorbable sutures are designed to be broken down and absorbed by the body over time, negating the need for removal. Chromic sutures are made from catgut that has been treated with chromium salts to slow down the absorption process, allowing for a longer duration of support as healing occurs. Monocryl, on the other hand, is a synthetic monofilament suture made from poliglecaprone, which provides excellent tensile strength and is completely absorbed within a relatively short time frame, typically within 90 to 120 days. This ability to be absorbed is particularly useful in surgical settings where it is critical to avoid the need for additional procedures to remove stitches, supporting optimal patient recovery while minimizing infection risks associated with non-absorbable sutures. The other options consist of materials that are not absorbable. Nylon and PDS are meant for prolonged strength and are typically used in situations where the suture might need to be retained for an extended period. Silk and Prolene are non-absorbable, with Prolene being a widely used synthetic option. Polyester and stainless steel are also recognized for their non-absorbable properties
