Which suture is a monofilament, non-absorbable suture used to close the peritoneum?

Prolene is a monofilament, non-absorbable suture that is commonly used in various surgical procedures, including the closure of the peritoneum. Its monofilament structure allows for smooth passage through tissues, reducing the risk of infection and tissue irritation. Being non-absorbable means that it retains its tensile strength over time, making it particularly suitable for areas where long-term support is required, such as in the peritoneal cavity.

In contrast, options like Vicryl, catgut, and silk are either absorbable or braided. Vicryl, for instance, is a natural or synthetic absorbable suture that loses strength over time, making it less suitable for long-term closures. Catgut is also absorbable and can cause tissue reaction, hence not ideal for certain applications. Silk is a braided, non-absorbable suture that can be more reactive and may harbor bacteria due to its construction, making it less favorable for internal closures like the peritoneum.
