Sutures for General Surgery — Complete Material Selection Guide
General surgery encompasses the widest range of suture applications, from laparotomy wound closure and bowel anastomosis to hernia repair and skin closure. Surgeons must select from absorbable and non-absorbable materials based on tissue type, healing timeline, contamination risk, and mechanical loading. A well-stocked suture portfolio is essential for the general surgical service.
Key Suture Selection Considerations
Fascial closure after laparotomy requires slowly absorbable monofilament sutures (PDO or PLLA-PCL) — the STITCH trial established that continuous small-bite technique with PDO reduces incisional hernia rates
Bowel anastomosis typically uses medium-term absorbable sutures — the tissue heals within 7-14 days and permanent sutures may cause erosion or fistula formation
Contaminated and dirty wounds favor monofilament sutures to reduce bacterial harboring — braided sutures increase infection risk in contaminated fields
Skin closure options include absorbable subcuticular sutures, non-absorbable percutaneous sutures, and staples — the choice depends on wound tension and cosmetic importance
Hernia mesh fixation may use non-absorbable polypropylene or slowly absorbable sutures depending on surgeon preference and mesh type
Drain site and port site closure in laparoscopic surgery typically requires only short-term absorbable sutures for fascial and skin layers
Recommended Desmo Care Sutures
DesmoNex
Coated PGA braided absorbable — the general surgery workhorse for peritoneal closure, subcutaneous tissue approximation, bowel serosa, and vessel ligation with 28-35 days of tissue support and excellent handling
DesmoPol
PDO monofilament with 180-day extended support — recommended for fascial closure after laparotomy using the evidence-based small-bite continuous technique to reduce incisional hernia rates
DesmoMid
Polypropylene monofilament — preferred for skin closure, hernia mesh fixation, contaminated wound closure, and any application requiring permanent non-absorbable support with minimal tissue reactivity
DesmoCryl
PGCL monofilament with smooth tissue passage — used for subcuticular skin closure in laparoscopic port sites and clean surgical wounds where cosmetic outcome and suture-removal avoidance are priorities
Clinical Notes & Best Practices
The European Hernia Society (EHS) and STITCH trial evidence strongly support continuous small-bite fascial closure with slowly absorbable monofilament sutures (PDO) at a suture-to-wound-length ratio of at least 4:1. This technique has been shown to reduce incisional hernia rates from 21% to 13% compared to large-bite closure. For bowel anastomosis, both single-layer and double-layer techniques show equivalent outcomes when using absorbable sutures; the key is secure serosal apposition. In contaminated and dirty wounds, monofilament sutures reduce surgical site infection rates by avoiding the capillarity effect inherent to braided sutures. Skin closure method should be tailored to wound location, tension, and patient factors — subcuticular absorbable closure provides equivalent outcomes to staples with better cosmetic results in clean incisions.
Frequently Asked Questions
What is the best suture for abdominal fascia closure?
▼
Current evidence (STITCH trial) supports slowly absorbable monofilament sutures like DesmoPol (PDO) for fascial closure using a continuous small-bite technique (5mm bites, 5mm intervals). This approach reduces incisional hernia rates compared to large-bite closure with rapidly absorbing sutures.
What suture is used for bowel anastomosis?
▼
Bowel anastomosis typically uses medium-term absorbable sutures like DesmoNex (PGA) in 3/0-4/0 gauge. The tissue heals within 7-14 days, and absorbable sutures eliminate the risk of suture erosion into the bowel lumen that can occur with permanent materials.
Should I use monofilament or braided sutures in contaminated wounds?
▼
In contaminated or dirty wounds, monofilament sutures (DesmoPol, DesmoCryl, or DesmoMid) are preferred because braided sutures harbor bacteria within their interstices through capillary action. Monofilament structure significantly reduces the risk of surgical site infection in contaminated fields.
What suture is recommended for hernia mesh fixation?
▼
Hernia mesh fixation commonly uses non-absorbable polypropylene sutures (DesmoMid) for permanent fixation, though some surgeons prefer slowly absorbable sutures (DesmoPol) to reduce chronic suture-related pain. The choice depends on mesh type, hernia location, and surgeon preference.
How do I choose between staples and sutures for skin closure?
▼
Staples are faster but produce inferior cosmetic results. For clean surgical wounds where cosmetic outcome matters, subcuticular closure with absorbable monofilament (DesmoCryl) provides equivalent wound strength with better appearance. Staples remain appropriate for scalp wounds and when speed is critical.
