When attempting to close abdominal incisions after surgery, monofilament sutures reduce the occurrence of incisional hernia, according to a recent Cochrane review. The same analysis also concluded that absorbable sutures reduce the likelihood of chronic wound drainage, including sinus or fistula formation.
- The Cochrane team reported on 55 studies that included over 19,000 patients.
- The studies looked at a variety of suture materials, closure techniques, and types of surgery.
- Absorbable sutures were compared to permanent sutures.
- Closing all the anatomical layers of the abdominal wall at the same time was compared to closure of individual layers.
- Continuous closure was compared to interrupted closure.
- Monofilament sutures were compared to braided multifilament sutures.
- Sutures that maintain their tensile strength for >30 days (slow absorbable) were compared to those that lost strength within 30 days.
