Evaluating the 1-Minute Sit-to-Stand Test for Predicting Postoperative Complications after Video-Assisted Thoracic Surgery Lung Lobectomy.

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.
