Healing process of laser-welded intestinal anastomosis.

abstract：BACKGROUND AND OBJECTIVE:Laser resurfacing with the 950 micros pulsed CO(2) laser is an effective treatment for photodamage and acne scarring; however, the potential for prolonged erythema and delayed re-epithelialization dissuade many patients from the procedure. With the use of erbium lasers alone, there is a decreas...
