Abstract
OBJECTIVE
Since its first report, video-assisted thoracic surgery (VATS) lung lobectomy was carried out with the use of conventional surgical instruments, used in laparoscopy and open thoracotomy. These instruments are expensive, not standardized and there are a variety of models and manufacturers. The aim of this study was to determine the impact of the use of these instruments on the experimental pulmonary lobectomy.
METHODS
We used a modified surgical simulator that uses a porcine heart-lung block filled with tomato sauce, and tested specific (Group 1) and regular (Group 2) instruments. Each group includes 15 experiments.
RESULTS
The median total time, excluding the time spent to correct the lesions, was 45.08 and 45.81 minutes, respectively in Group 1 and Group 2. There was no statistical difference between the total times (p=0.58). The only statistically different was seen for partial times regarding the elapsed time to cut and suture of lung fissures (p=0.03 and 0.04, respectively). There were more direct lesions and indirect leaks in Group 2, but without statistical significance (p=1.000 and p=0.203, respectively). The mean time spent for the diagnosis and correction of these events was 1.77 minutes with a standard deviation of 1.18 for Group 1 and 2.72 ± 1.11 minutes for Group 2 (p=0.044).
CONCLUSION
The use of minimally invasive instruments is not associated with time improvement spent with experimental video-assisted lung lobectomy and does not lead to a faster or safer surgery. The use of VATS instruments makes correction of adverse events faster when they occur.
