    Summary

    Necrotizing fasciitis, a severe soft tissue infection, presents differently based on origin. Postoperative cases show mixed aerobic-anaerobic infections, while retroperitoneal cases are dominated by anaerobic bacteria, leading to vastly different patient outcomes.

    Area of Science:

    • Infectious Diseases
    • Surgical Complications
    • Microbiology

    Background:

    • Necrotizing fasciitis is an increasingly frequent and severe complication.
    • Understanding its diverse origins and clinical presentations is crucial for effective management.
    • Two distinct patient groups were identified based on the etiology and progression of necrotizing fasciitis.

    Purpose of the Study:

    • To analyze and compare clinical experiences with necrotizing fasciitis in two distinct patient cohorts.
    • To investigate the microbiological profiles associated with different origins of necrotizing fasciitis.
    • To evaluate the impact of etiology and causative microorganisms on patient outcomes.

    Main Methods:

    • Retrospective clinical case review of 17 patients with necrotizing fasciitis.
    • Categorization into two groups: postoperative (Group 1, n=11) and retroperitoneal (Group 2, n=6).
    • Comprehensive microbiological examinations of wound and tissue samples from 13 patients.

    Main Results:

    • Group 1 (postoperative) exhibited aerobic-anaerobic mixed infections, predominantly Enterobacteroidaceae. Survivorship was 62.6%.
    • Group 2 (retroperitoneal) showed a prevalence of anaerobic bacteria, primarily Clostridium species. Survivorship was 16.6%.
    • Significant differences were observed in the timing of septic complication onset and clinical manifestations between the two groups.

    Conclusions:

    • The origin of necrotizing fasciitis significantly influences its clinical course, microbiological findings, and patient prognosis.
    • Postoperative necrotizing fasciitis, often polymicrobial, has a better survival rate than retroperitoneal necrotizing fasciitis, which is frequently caused by anaerobic bacteria.
    • Tailored therapeutic strategies based on the specific etiology and identified pathogens are essential for improving outcomes in necrotizing fasciitis.
