Predictors of general complications after video-assisted thoracoscopic surgical procedures. 2008
BACKGROUND The video-assisted thoracoscopic approach has become the preferred method for many procedures due to the reduced trauma, complication rate and morbidity. The aim of this study was a risk evaluation of patients undergoing video-assisted thoracoscopic surgery (VATS) procedures. METHODS Between 1991 and 2004, 1,008 patients were included in this single-center retrospective analysis. Risk assessment was performed using univariate and multivariate analysis. RESULTS Multivariate analysis revealed that patient age (p = 0.003), the duration of the VATS procedure (p = 0.008), redo-VATS (p < 0.001) and conversion to open thoracotomy (p < 0.001) correlated significantly with the incidence of complications. Patients with immune deficiency following organ transplantation had the highest complication rate at 31.7%, which was significantly higher than for patients with either benign disease (p = 0.010) or malignant disease (p = 0.019). CONCLUSIONS VATS is a safe procedure, but extra caution is recommended for patients with a higher risk profile (age, redo-VATS, immune deficiency).
