Other
Other related information The objective variable was the occurrence of postoperative pneumonia. Pneumonia was diagnosed via the presence of fever, elevated white blood cell counts, and pulmonary infiltrates requiring antibiotic therapy. we defined the predictor variables as: 1) patient factors: age, sex, body mass index, smoking habit, drinking habit, diabetes, hypertension, preoperative serum creatinine, preoperative serum albumin, and forced expiratory volume 1%; 2) tumor factors: site and stage; 3) treatment factors: thoracotomy, operation time, blood loss, neoadjuvant chemotherapy, and postoperative dysphagia; and 4) oral care intervention. Patients who had not smoked for >1 year were classified as not having a smoking habit. The tumor sites were divided into the upper, middle, and lower esophagus. Tumor staging was classified according to the Japan Esophageal Society's criteria. Postoperative dysphagia was defined as choking when the patient started a paste diet after surgery, exhibited aspiration during swallowing (via videofluoroscopic examination), or continued tube feeding at the time of discharge.
