Which type of suture has the longest absorption period?

The type of suture with the longest absorption period is poliglecaprone 25. This suture material, a synthetic monofilament, offers excellent tensile strength and is gradually absorbed by the body over a period of approximately 180 to 240 days. This prolonged absorption time makes it suitable for applications where sustained support is needed before the tissue fully heals.

In comparison, chromic gut is absorbed within about 90 days, while plain gut tends to have a shorter absorption timeframe, typically around 70 days. Polyglactin 910, although it offers a reasonable absorption duration of about 50 to 70 days, is still considerably shorter than that of poliglecaprone 25. Thus, when selecting a suture material for surgical procedures requiring a longer duration of support, poliglecaprone 25 is the preferred choice due to its extended absorption characteristics.
