From the Research
Self-dissolving stitches typically take 1-3 weeks to dissolve completely, though this timeframe varies based on several factors, as supported by the most recent study 1 comparing poliglecaprone-25 and polyglactin-910 in subcuticular skin closure at cesarean delivery. The location of the stitches significantly affects dissolution time, with stitches in areas with good blood supply (like the face) dissolving faster than those in areas with less circulation (like the feet). The type of suture material also matters - "fast-absorbing" gut sutures may dissolve within 5-7 days, while synthetic materials like polyglycolic acid (Vicryl) can take 2-3 weeks, and polydioxanone (PDS) sutures may last 3-6 months for deeper tissue layers. Some key points to consider include:
- The comparison of poliglecaprone-25 and polyglactin-910 in subcuticular skin closure at cesarean delivery, as studied in 1, showed similar composite wound complications but differing pain scores.
- The study in 2 comparing poliglecaprone-25 and polyglactin-910 in cutaneous surgery found poliglecaprone-25 resulted in significantly less extruded sutures.
- The in vitro comparison in 3 of mechanical and degradation properties of equivalent absorbable suture materials from two different manufacturers highlighted differences in properties between nominally identical sutures. Your body's individual healing rate and the presence of infection can also influence dissolution time. It's essential to follow your healthcare provider's specific aftercare instructions, which typically include keeping the wound clean and dry. If you notice signs of infection (increasing redness, swelling, pain, or discharge), or if stitches remain beyond the expected timeframe, contact your healthcare provider promptly, as indicated by the findings in 4 and 1.
