Background: To explore the clinical profiles and outcomes of patients with acute respiratory failure (ARF) after esophagectomy.
Methods: We retrospectively analyzed cases of patients who had been diagnosed with ARF after esophagectomy and compared survivors with non-survivors to explore the risks that may affect their outcomes.
Results: In total, 62 patients were admitted to the intensive care unit (ICU) with ARF after esophagectomy between January 1, 2010, and December 31, 2017. Of these patients, 69.4% needed mechanical ventilation, with an average time on the ventilator of 304 hours (304.33±374.37 hours). The average length of stay in the ICU and in the hospital were 14 days (14.48±17.64 days) and 50 days (50.15±37.28 days), respectively. Mortality in the ICU and 90 days after the operation was 6.5% and 16.1%, respectively. Compared with the survivors, the 90-day post-operative non-survivors had a poorer N stage in the TNM classification system. The causes of ARF included anastomotic leakage, pneumonia, vocal cord paralysis, sputum plugging, pulmonary embolism (PE), and acute respiratory distress syndrome (ARDS). ARF induced by different factors occurred at different times and had different outcomes. The three most common reasons for mortality in the ICU were ARDS (33.33%), anastomotic leakage (11.76%), and pneumonia (10%). The three most common reasons for mortality in the 90-day post-operative period were pneumonia (40%), anastomotic leakage (23.53%), and ARDS and acute exacerbations of chronic obstructive pulmonary disease (AECOPD) (33.33%).
Conclusions: Anastomotic leakage, pneumonia, ARDS, and AECOPD were the main causes of death in ARF patients after esophagectomy. We found that the N stage in the TNM classification system may affect 90-day post-operative mortality in these patients.
