- Abstract
- To determine the predictive value of identifying calcified lymph nodes (LNs) for the perioperative outcomes of video-assisted thoracoscopic surgery (VATS).Fifty-six consecutive patients who underwent VATS lobectomy for lung cancer were included. We evaluated the number and location of calcified LNs on computed tomography (CT). We investigated clinical parameters, including percentage forced expiratory volume in 1 s (FEV1%), surgery duration, chest tube indwelling duration, and length of hospital stay. We performed linear regression analysis and multiple comparisons of perioperative outcomes.Mean number of calcified LNs per patient was 0.9 (range, 0-6), mostly located in the hilar-interlobar zone (43.8 %). For surgery duration (mean, 5.0 h), FEV1% and emphysema severity were independent predictors (P = 0.010 and 0.003, respectively). The number of calcified LNs was an independent predictor for chest tube indwelling duration (P = 0.030) and length of hospital stay (P = 0.046). Mean duration of chest tube indwelling and hospital stay was 8.8 days and 12.7 days in no calcified LN group; 9.2 and 13.2 in 1 calcified LN group; 12.8 and 19.7 in a parts per thousand yen2 calcified LNs group, respectively.The presence of calcified LNs on CT can help predict more complicated perioperative course following VATS lobectomy.aEuro cent Preoperative chest CT can help predict perioperative outcome following video-assisted thoracoscopic surgery.aEuro cent Calcified lymph nodes should be assessed on CT to predict perioperative outcome.aEuro cent Multiple calcified LNs are associated with longer chest drainage.aEuro cent Hospital stay appears longer in patients with more calcified lymph nodes.
