Subcutaneous closure versus no subcutaneous closure after non-caesarean surgical procedures.

Most surgical procedures involve a cut in the skin that allows the surgeon to gain access to the surgical site. Most surgical wounds are closed fully at the end of the procedure, and this review focuses on these. The human body has multiple layers of tissues, and the skin is the outermost of these layers. The loose connective tissue just beneath the skin is called subcutaneous tissue, and this generally contains fat. There is uncertainty about closure of subcutaneous tissue after surgery: some surgeons advocate closure of subcutaneous tissue, as they consider this closes dead space and leads to a decrease in wound complications; others consider closure of subcutaneous tissue to be an unnecessary step that increases operating time and involves the use of additional suture material without offering any benefit.
