One of the trickiest parts of surgery is also the most commonplace: sutures to close incisions.
Infections and scarring at the site of sutures are frequent concerns of surgeons as well as patients. One recent advancement, laser tissue welding (LTW), holds the promise of reducing suturing problems while also shortening operation times.
