INTRODUCTION: The efficacy of surgical intervention for perianal infection in patients with hematologic malignancy is not well-established. OBJECTIVE: This article presents a case series of perianal infection progressing to Fournier's gangrene (FG) in patients with hematologic malignancy to guide physicians, because to the author's knowledge, there were no randomized or prospective studies presenting the management strategies reported herein. It was hypothesized that surgery might reduce mortality and morbidity in patients with inflammation spreading beyond the perianal region, in patients with abscess formation, and in those who show no improvement with medical therapy. MATERIALS AND METHODS: The data of 4 adults with hematologic malignancy who developed perianal infection progressing to FG between January 2010 and December 2018 were reviewed retrospectively. Patients younger than 18 years and patients without hematologic malignancies or FG were excluded. The primary outcome was mortality. The secondary outcome was irreversible organ damage. RESULTS: Four male patients with a mean age of 36.75 years ± 13.1 standard deviation (range, 23-52 years) reported fever and dull anal pain during treatment for hematologic malignancy. A broad-spectrum antibiotic regimen was administered as initial empiric therapy at onset of fever and was de-escalated based on the culture results and clinical response. However, FG arose in all cases approximately 8.75 days ± 6.94 (range, 3-17 days) after onset of anal pain. All patients underwent surgical debridement, and diverting ostomy was performed in 3 cases. One patient died of overwhelming sepsis (25%), and 1 patient required orchiectomy (25%). CONCLUSIONS: Clinical suspicion of FG may be effective in reducing mortality in patients with hematologic malignancy, especially in cases with fever accompanied by anal pain. Surgical intervention may improve the prognosis for patients with inflammation spreading beyond the perianal region, patients with abscess formation, those who show no improvement in medical therapy, and those who develop FG. Diverting ostomy may improve survival in patients with FG. |
