Abstract
This study aimed to use a new special inventory for lung surgery patients to evaluate postoperative symptoms and functional status and to identify factors that may affect these after uniportal video-assisted thoracoscopic surgery (VATS). In this single-center longitudinal cohort observational study, we used a new scale, the perioperative symptom assessment for lung surgery (PSA-Lung), to evaluate the recovery from symptoms and the functional status of patients undergoing uniportal VATS. We divided patients into two groups, according to patients' symptom scores, and compared the clinical characteristics between the two groups under each item. Then, we conducted a qualitative interview regarding coughing in postoperative week 4. Exactly 104 patients were enrolled in this study. The two highest-scoring patient-reported outcome (PRO) items were "shortness of breath" and "coughing" in the fourth week after surgery. Thirty-one patients reported that "coughing" severely influenced their lives in postoperative week 4. Using the PSA-Lung inventory, we found that "shortness of breath" was the worst symptom in postoperative week 4. Although "coughing" was not the most important symptom in the early postoperative period, it affected some patients' lives in postoperative week 4. Therefore, further research is required to determine the optimal cut-off point for coughing.
