Fournier’s gangrene: a retrospective review of management outcomes and seasonal variations of clinical presentation

Abstract

Abstract Background To review retrospectively the outcomes of management of Fournier’s gangrene (FG) and to assess for possible seasonal variations in clinical presentations of FG to a referral hospital in a tropical African country. Methods The medical records of patients who presented with FG from February 2012 to December 2019 were reviewed. Of interest were age of patient, vital signs at presentation, site of gangrene, duration of hospital admission, and management interventions deployed. Analysis was with SPSS® version 21. Results Twenty-three of 28 medical records could be analyzed. Median Fournier’s Gangrene Severity Index (FGSI) was 5 (IQR:3–10), the median Uludag-FGSI (UFGSI) was 7 (IQR:4–14). In 82.6%, the scrotum was the site of onset; in 8.7%, the lesion had spread beyond the pelvis. Diabetes mellitus (30.4%), HIV infection (13.0%) and nephropathy (17.4%) were identified co-morbidities. There were 2.4 ± 1.0 debridement sessions and 1.5 ± 1.3 transfused units of blood per patient. In 60.9%, the wound edges were undermined and apposed; in 17.4%, split skin grafting or fascio-cutaneous flap cover was deployed. In 17.4%, satisfactory wound closure needed more than 1 theater session. Mean duration of hospital admission was 51.4 ± 19.4 days. No mortality was recorded. Majority (91.2%) presented in hot, dry months of October through March with peak in December. No case presented in the wet months of May through September. Conclusion Meager resources notwithstanding, FG management outcomes are generally satisfactory. Furthermore, FG is observed to present mostly in the hot, dry months of the year in the 8 years under review.
