Abstract
Objectives: Left
upper mediastinal node dissection (LUMND) under video-assisted thoracoscopic
surgery (VATS) may be more difficult than thoracotomy. The aim of this study is to assess quality of left
upper mediastinal node dissection, especially left lower paratracheal node (4L)
dissection.
Patients and Methods: 60
patients with lung cancer located in left upper lobe were operated between
January 2013 and December 2016 in our institute. Of those, 33 VATS lobectomy
and 27 open lobectomy were compared in terms of dissected node number. Intentional
LUMND in VATS is defined as MND including left lower paratracheal node (4L)
dissection with curative intent and non-intentional LUMND is sampling of 4L.
Our procedures of LUMND is that left recurrent ralyngeal nerve is isolated from Botallo ligamentum and completely isolated as
far as possible by endoscissors. 4L are dissected from trachea and left main
bronchus both distal and proximal direction. Dissected lymph node number was
compared between intentional and non-intentional LUMND.
Conclusions: Our
study demonstrated that intentional LUMND was not inferior to open procedure in
terms of dissected lymph node number. VATS LUMND may be promising oncological
outcomes under node dissection with curative intent.
