Welcome
to this series of CTSNet videos on Thoracic Surgical Oncology - Technical
Approaches, by Professor Tristan D. Yan.
An electroevaporative surgical technique is demonstrated in this video. This is
a unique surgical approach that can be used in all major thoracic surgical
oncology cases. Generous warm saline solution is injected under gentle pressure
between the tumor and the normal tissues with a bulb-syringe. The saline
solution has a tendency to be absorbed by adhesions, creating a small amount of
separation along the dissection planes. The special tool used to dissect tumor
from the surrounding tissues is a 3mm ball-tip electrosurgical hand-piece,
which is used at a high voltage. This creates an electrical arc on the blunt
ball-tip that contours the dissection plane rather than cutting through the
structures beneath. The 3mm ball-tip electrode can be used for dissecting along
the extra-pleural surfaces and on the mediastinal structures. The main
advantages of the electroevaporative technique include blood-less operative
field, minimal risk of vascular injury and precise tumor dissection.
Also presented in this video is the "Coliseum" approach for giant
thoracic tumors. Usually, these tumors firmly occupy the entire ipsilateral
thoracic cavity (ie. “Frozen Thorax”), splay the ribs, compress the
hemi-diaphragm, and grossly displace the mediastinal structures to the
contralateral side. This mass effect is usually profound and causes impedance
of venous return, and reduction in cardiac output. A systematic
surgical-oncological approach is required in order to achieve complete
cytoreduction
