Laparoscopic surgery of postero-lateral segments: a comparison between transthoracic and abdominal approach.

Lesions located in the postero-lateral part of the liver (segments 6 and 7) have been considered as poor candidates for a laparoscopic liver resection due to the limited visualization and difficulty in bleeding control. Although no comparison has been done between transthoracic and abdominal resection of tumors located in the postero-lateral segments, we propose a description of these different strategies, specifying the benefits as well as the disadvantages of the various approaches.
