Early treatment of necrotizing fasciitis secondary to perianal abscess

BACKGROUND: The present study analyzed the surgical treatment effects of necrotizing fasciitis secondary to perianal abscess at different treatment times to determine a better treatment approach. METHODS: Sixty-four patients of necrotizing fasciitis secondary to perianal abscess who were hospitalized and received surgical treatment in the past 5 years were analyzed retrospectively. Statistical comparisons of postoperative condition were performed in patients who were divided into two groups based on infection etiology with regard to different treatment times, hospitalization duration, wound healing time, average number of operations, septic shock, and mortality, which were analyzed by one-way analysis of variance or the χ2 test. RESULTS: Significant differences (P < 0.05) were found for hospitalization duration, wound healing time, average number of operations, septic shock, and mortality between type I and type II patients at different treatment times. CONCLUSIONS: Radical surgical treatment of type I and type II patients with necrotizing fasciitis who underwent surgery at an early disease stage had a better outcome than patients who underwent surgery at a later stage, and type II patients required earlier surgical intervention.
