Necrotizing fasciitis of the abdominal wall

Necrotizing fasciitis of the abdominal wall is a necrotizing soft tissue infection occurring in the abdominal wall. There are multiple causative bacteria. The infection mainly involves the deep and superficial fascia of the abdominal wall and may also invade the skin, but muscles are not affected in the early stage. This disease can occur at any site of the abdominal wall (such as the anterior abdominal wall, lateral abdominal wall, groin area, and posterior abdominal wall), especially at or near abdominal trauma or surgical incision (wound) sites, and may also result from spread of infection from the buttocks or perineum, sometimes occurring after minor puncture wounds or insect bites. Necrotizing fasciitis has an acute onset, rapid progression, and critical condition; delayed diagnosis and treatment often lead to patient death.
