ObjectiveTo determine the frequency and risk factors for pulmonary complications in elderly patients undergoing combined thoracolaparoscopic radical esophageal cancer surgery, and to develop a predictive model for pulmonary complications occurrence.Study DesignObservational study. Place and Duration of the Study: Department of Thoracic Surgery, Lujiang County People's Hospital, Anhui Province, China, from January 2017 to August 2022.MethodologyTwo hundred and sixty elderly patients who underwent combined thoracic and laparoscopic radical esophagectomy were included. Univariate and multifactorial analyses were performed to identify risk factors for pulmonary complications, and a predictive model was developed using significant factors.ResultsPulmonary complications occurred in 27.69% of patients. Advanced age, smoking index, diabetes mellitus, tumour location, advanced clinical stage, intraoperative bleeding, duration of operation, and postoperative mechanical ventilation time were significantly associated with pulmonary complications (p<0.05). Multifactorial analysis identified advanced age, diabetes, smoking index, advanced clinical stage, and time of surgery as independent risk factors for pulmonary complications. The prediction model had good predictive efficacy with an area under the ROC curve of 0.857, sensitivity of 83.3%, and specificity of 71.1%.ConclusionCombined thoracolaparoscopic radical esophageal cancer surgery has a high incidence of pulmonary complications in elderly patients. Advanced age, diabetes, smoking index, advanced clinical stage, and time of surgery are independent risk factors for pulmonary complications, and the developed predictive model will be contributing to identify high-risk patients.Key WordsEsophageal cancer, Elderly patients, Pulmonary complications, Risk factors.
