NEWER SURGICAL STAGING TECHNIQUES

Newer surgical staging techniques
videomediastinoscopy the ancient mediastinoscope
consists in principle of a tube with a lightweight. this has been modified
to embrace an optical system that provides a far more
detailed read and permits a far more in depth operation of
nodes and different structures. qualitatively, videomediastinoscopy
allows actual operation of nodal stations and removal of
entire nodes. in a veryddition, the fascial plane separating the anterior
pretracheal house and therefore the subcarinal house may be opened.
operation directly adjacent to the carina and bronchi allows
the subcarinal nodes to be mobilized, providing access to the
posterior subcarinal nodes that are thought to be relatively inaccessible
via ancient mediastinoscopy. information from many series
confirms an advantage over ancient mediastinoscopy for staging
of the mediastinum : the average reported sensitivity is 90%,
fn rate 7% ( compared with approximately 80% and 13% for
ancient mediastinoscopy ).
