Purpose: This study aimed to determine whether the 1-minute sit-to-stand test (1-min STST) can be a predictor of postoperative complications following video-assisted thoracic surgery (VATS) lung lobectomy.
Methods: This retrospective cohort study included 152 patients who underwent VATS lobectomy. Preoperative evaluations included pulmonary function tests, the bendopnea test, and the 1-min STST. The predictive value of these assessments for postoperative complications, graded by the Clavien–Dindo (C–D) classification, was analyzed using logistic regression and receiver-operating characteristic curves.
Results: For predicting C–D grade II or III complications, a 1-min STST repetition count of ≤20 had an area under the curve (AUC) of 0.70, with 90% sensitivity and 46% specificity. For predicting C–D grade III complications, a repetition count of ≤15 showed an AUC of 0.72 (95% confidence interval [CI], 0.39–1.00), with 97% sensitivity and 60% specificity. In multivariate analysis for C–D grade III complications, a lower 1-min STST repetition count was a significant predictor (p <0.01).
Conclusion: The 1-min STST shows potential as a simple tool for preoperative risk stratification in patients undergoing VATS lobectomy.
