seromuscular suture
Pronunciation: seer-oh-MUS-kyoo-lar
A surgical suture technique that includes only the outer layers of the bowel wall, avoiding penetration of the mucosa.
Full Definition
A seromuscular suture is a surgical technique that incorporates only the serosal and muscular layers of the intestinal wall while deliberately avoiding the mucosal layer. This suturing method is commonly used in bariatric surgery for reinforcing anastomoses, creating antireflux mechanisms, and securing omental patches. The technique reduces the risk of luminal contamination while providing adequate tissue strength for healing. In procedures like fundoplication or jejunojejunostomy, seromuscular sutures help create durable connections without exposing the surgical field to intestinal contents. Proper technique requires precise depth control to avoid inadvertent mucosal penetration.
Usage
Usage note: Avoids mucosal layer; used for reinforcement and leak prevention.
