Background: Anorectal complications are common in patients with haematological malignancies. Objectives: The objectives are to characterize anorectal complications in these patients, identify risk factors and shed light on treatment, morbidity and mortality rates. Patients and methods: A retrospective, observational study that included 83 inpatients with haematological malignancies and proctological symptoms from January 2010 to September 2015 was conducted. Clinical outcomes were obtained through a detailed review of medical records. Results: The median age was 56 years, and 52 (62.7%) patients were men. Fifty-six (67.5%) patients had nonseptic anorectal complications and 27 (32.5%) patients had septic anorectal complications. Risks factors: Patients with septic anorectal complications were more commonly male, older, and had lower absolute neutrophil counts, but the differences were not statistically significant (P=0.79, 0.67 and 0.89, respectively). In positive blood cultures [23/70 (32.9%)], Enterococcus faecium, Klebsiella pneumonia, and Escherichia coli were the most common isolated agents. Treatment: In nonseptic anorectal complications, conservative treatments/minor proctological procedures were adopted, and patients with septic anorectal complications were treated with antibiotics±major proctological procedures and/or surgical drainage/debridement. Results of treatment: Forty-eight (85.7%) patients in the nonseptic complications group improved compared with 23 (85.2%) patients in the septic complications group. The overall mortality rate was 2.4% (n=2), with one (1.2%) death related to perianal sepsis. Conclusion: Enterococcus spp. were more commonly identified in this study and can be increasing in this specific population. In contrast to other reports, we did not identify an association between septic anorectal complications and possible risk factors such as male sex, younger age or a low absolute neutrophil count. Most patients had nonseptic anorectal complications. A major proctological procedure/surgical debridement should always be applied in septic complications, which have better prognoses now than in the past.
