Comparison of Wound Healing for Diabetic Carbuncle Treated With Incision and Drainage Technique Using Cruciate Incision vs Saucerization Technique Both Followed by Vacuum Assisted Closure.

This is a less radical procedure focused on establishing a drainage pathway for the underlying pus collection. It involves making a cruciate (cross-shaped) incision over the carbuncle. Unlike saucerization, it does not involve wide excision of tissue. Postoperatively, broad-spectrum antibiotics are administered to control the remaining cellulitis and infection. This technique is associated with less blood and tissue loss, a smaller final scar, and potentially faster initial healing. However, the patient's postoperative hospital stay may be prolonged until the sepsis is adequately controlled with antibiotics.

This is a radical surgical procedure for a diabetic carbuncle. It involves the complete excision of all dead (necrotic) tissue at the center of the infection, along with the surrounding area of cellulitis. The goal is to achieve healthy, bleeding margins and remove the entire septic focus. While this extensive removal may eliminate the need for postoperative antibiotics, it is associated with significant intraoperative blood loss, which can necessitate a blood transfusion. The procedure results in a large wound that heals by secondary intention, often requiring subsequent skin grafting or flap coverage and leading to a larger scar.
