ObjectiveTo analyze the impact of infectious complications and microbiology in the postoperative period after major oncologic neck surgeries.MethodsA retrospective study conducted in an oncology center, including all the consecutive patients who developed infectious complications after major neck cancer surgery, from October 2012 to May 2016 (44 months). Among other data, we collected TNM stage, ASA score, body mass index, comorbidities and habits, pre and postoperative hemoglobin levels, albumin serum levels, pre-surgical treatments, length of inpatient stay, isolated microbiological agents and the recorded complications and mortality rate.ResultsIn the studied period, 761 major neck surgeries were performed. Of these, 96 patients had complications (12.6%). Pharyngocutaneous fistula (PCF) was the most frequent complication (56%) and nosocomial pneumonia was the most common systemic complication (23%). Pseudomonas aeruginosa was the principal microorganism of the 26 species isolated (15%). 12 deaths were registered. Using multiple linear regression we concluded that flap/cutaneous necrosis and PCF were complications with statistical significance that prolonged inpatient stay. The same complications had significant relative risk for more than 30 days of hospitalization.ConclusionThe postoperative period is critical for the successful treatment of head and neck oncology patients. PCF and flap/cutaneous necrosis were the principal complications which worsened the outcomes during this critical period. The early recognition and treatment of these complications is crucial.
