Abscess Incision and Drainage (Encyclopedia of Surgery)
An abscess is an infected skin nodule containing pus. It may need to be drained via an incision (cut) if the pus does not resolve with treatment by antibiotics. This allows the pus to escape, the infection to be treated, and the abscess to heal.
An abscess is a pus-filled sore, usually caused by a bacterial infection. The pus is comprised of both living and dead organisms. It also contains destroyed tissue due to the action of white blood cells that were carried to the area to fight the infection. Abscesses are often found in the soft tissue under the skin such as the armpit or the groin. However, they may develop in any organ, and are commonly found in the breast and gums. Abscesses are far more serious and call for more specific treatment if they are located in deep organs such as the lung, liver, or brain.
Because the lining of an abscess cavity tends to interfere with the amount of drug that can penetrate the source of infection from the blood, the cavity itself may require draining. Once an abscess has fully formed, it often does not respond to antibiotics. Even if the antibiotic does penetrate into the abscess, it does not function as well in that environment.
