Surgical intervention after induction chemoradiation is designed as curative treatment for resectable stage III/N2 non-small cell lung cancer. However, there is no definitive evidence to support this approach, possibly because successful treatment requires certain "arts", such as proper patient selection, an appropriate induction regimen, and choice of the best surgical procedure. We review the previous reports and discuss our own experience to explore the appropriate strategy for patients with resectable stage III/N2 disease, and to identify the factors associated with successful surgical intervention...

REVIEW
Zenichi Morise
Laparoscopic liver resection (LLR) was introduced in the early 1990s, initially for partial resection of the anterolateral segments, from where it has expanded in a stepwise fashion. Movement restriction makes bleeding control demanding. Managing pneumoperitoneum pressure with inflow control can inhibit venous bleeding and create a dry surgical field for easier hemostasis. Since the lack of overview leads to disorientation, simulation and navigation with imaging studies have become important. Improved direct access to the liver inside the rib cage can be obtained in LLR, reducing destruction of the associated structures and decreasing the risk of refractory ascites and liver failure, especially in patients with a cirrhotic liver...
