When closing fascia after a laparotomy, which suture is preferred?

When closing fascia after a laparotomy, polydioxanone (PDS) is often preferred due to its specific properties that make it well-suited for this type of tissue. PDS is a synthetic absorbable suture that provides strength and support during the crucial healing phase of fascia, which is a dense connective tissue. The timeline for PDS absorbability aligns well with the healing process, often providing adequate tensile strength for several weeks, which is necessary for the fascia to properly heal and regain its structural integrity.

Using PDS allows for enough time for the underlying tissues to heal sufficiently before the suture material is absorbed, minimizing the risk of dehiscence or other complications. The gradual breakdown of PDS also reduces the chance of a foreign body reaction. In contrast, other materials such as Goretex, plain gut, and Nurolon may not provide the ideal combination of handling, absorption rate, and strength needed in this specific application.
