Thoracoscopy, or
Video Assisted Thoracic Surgery (VATS), is a minimally invasive (keyhole) surgical
procedure. It allows the surgeon to directly examine the chest cavity without
a big incision. Three or four small incisions will be made on your chest, under
your arm or on your back. These incisions are made to allow the surgeon to use
the special instruments (video camera and stapler) needed for this operation.
A very small video camera is used to project pictures of the chest cavity onto
a screen during the procedure. Although it is an alternative to an open chest
operation, it is still considered major surgery.
Mediastinal tumors are masses
of abnormal tissue in the midportion of the chest. The area around the heart,
esophagus, and trachea may be involved and require chest operations to treat the
tumor by removal
Three main types of surgery are used in lung cancer treatment.
The choice depends on the size and location of the tumor, the extent of the cancer,
the general health of the patient, and other factors. An operation to remove only
a small part of the lung is called a segmental or wedge resection. When the surgeon
removes an entire lobe of the lung, the procedure is a lobectomy. Pneumonectomy
is the removal of an entire lung.
