Proctitis in patients with monkeypox infection: a single-center analysis of 42 consecutive cases from a multidisciplinary observational study on monkeypox proctitis

BACKGROUND: The current monkeypox (MP) virus outbreak was declared an international emergency in July 2022. The aim of this report is to describe our initial experience with patients with MP, focusing on proctitis. METHODS: We conducted an observational study between 20 May and 31 July 2022, on patients with MP at a reference tertiary center in Madrid, Spain. A descriptive analysis on MP was performed, focusing on its characteristics, symptoms, diagnosis, and outcomes. RESULTS: A total of 143 positive MP cases were diagnosed in our center; 42 of them [all male, median age 39 years (range: 22–57 years)] had proctitis (29.37%), and 3 patients (2.09%/MP total cases and 7.14%/MP proctitis) required surgical drainage of a perianal abscess. CONCLUSIONS: General and digestive surgeons must be aware of the presence of proctological impairment and complications due to MP virus.
