title: [Results of the video-assisted thoracic surgery lobectomy at our department in the last five-year periode].
abstract: OBJECTIVE
  Herein we present the results of lobectomies performed with minimally invasive approach (video-assisted thoracic surgery - VATS) at our department during a period of five years.
  
  
  METHODS
  Between 1 January 2011 and 31 December 2015, 197 lobectomies (malignant lesions: 176 cases, benign lesions: 21 cases) were performed by three thoracic surgeons and one resident. Demographical data are as follows: 119 female/78 male, mean age: 62.4 years (range: 41-82 years). In 2011 three VATS lobectomies were performed, equaling 2.2 % of all lobectomies in that year. During the upcomig years the number of VATS lobectomies were as follows: 2012: 7 (7.3%), 2013: 13 (12%), 2014: 59 (34.5%) and 2015: 119 (68.5%). In 153 cases multiportal (78%) and in 44 cases uniportal (22%) anterior approach was performed. The resected lobes showed the following distribution: right upper: 85, mid lobe: 5, right lower: 28, left upper: 44, left lower: 34, upper bilobectomy: 1. In two cases sleeve lobectomy was performed. In 8 cases (4%) conversion to thoracotomy was needed and among the 46 uniportal procedures, 5 cases needed to be expanded into biportal approach (11%).
  
  
  RESULTS
  During the study period, no intraoperative, or perioperative mortality occured. Mean operative time was 123 minutes (range: 60-135 minutes) and mean time of chest drainage was 4.3 days (range: 1-27 days). Air leakage lasting more than 7 days was present in 11.7%. Reoperation was needed in 4 cases (2%), in two cases due to bleeding, and in two cases because of expansive difficulties due to extended subcutaneous emphysema. Among the 176 VATS lobectomies performed due to malignant lesions, 169 lung cancers and 7 metastases were removed. The distribution according to the stage and histology of lung cancers was as follows: IA: 100 cases, IB: 28 cases, IIA: 17 cases, IIB: 3 cases, IIIA: 16 cases, IIIB: 1 case, and IV: 4 cases; adenocarcinoma: 128 cases, squamous cell carcinoma: 26 cases, large cell carcinoma: 3 cases, small cell lung cancer: 1 case, typical carcinoid: 10 cases, and atypical carcinoid: 1 case.
  
  
  CONCLUSIONS
  Over the years VATS lobectomy became a rutin procedure at our institution. Nowadays more than two-thirds of lobectomies are performed with minimally invasive technique. Taking the learning curve of the four thoracic surgeons into consideration, our results correlate with international data.
