“…Thirty patients from 6 studies [12,21,22,24,29,33] have been treated with the use of VATS, although the actual number may be less than 30 due to overlapping of a few patients between references [12] and [33]. The mean postinjury day of operation varied among the studies: 4 [22], 10.3 [33], and 23.7 days [29].
