ANS: B
Skin staples are removed 5 to 7 days postoperatively. As the skin heals, it flattens out to form an even surface with excellent cosmetic results if they have been placed lightly over the skin and are not embedded. Staples can be placed through an endoscope, and they produce an air-tight, leak-proof closure.
