Aims: The purpose of this study was to identify the risk factors for major adverse events of VATS (Video-Assisted Thoracic Surgery) lobectomy for primary lung cancer.

Methods: 1806 Patients (1032 males, 57.1%) planned to undergo VATS lobectomy for stage IA-IIIA lung cancer from July 2007 to June 2012. The Thoracic Morbidity and Mortality Classification TM&M system was used to evaluate the presence and severity of complications. Postoperative complications were observed during a 30-day follow up. Univariate and multivariate analysis were used to analyze the independent risk factors for major adverse events.

Results: Successful rate of VATS lobectomy was 97.6% (1763/1806). Major complications occurred in 129 patients (7.3%), with a mortality of 0.3% (5/1763). Pulmonary complications contribute up to 90.7% of the major complications and 80% of mortality. Logistic regression indicated that comorbidities, elder age ≥70y, operative time ≥240min and hybrid VATS were predictors for major adverse events (P<0.05). Hybrid and converted VATS lobectomy result in higher major adverse events compared with complete VATS, 15.1%, 20.9% and 7.4% respectively (P=0.013).

Conclusions: The overall complication rate and mortality of VATS lobectomy are low, while major complications sometimes occur. Pulmonary complications are the most common major complications and cause of mortality. Age ≥70y, comorbidities, operative time ≥240min and Hybrid VATS are predictors of major adverse events.
