Laparoscopic liver resection for posterosuperior tumors using caudal approach and postural changes: A new technical approach

Figure 3 Schema of the settings for semi-prone positioning and port placement. A: The patient is placed in the semi-prone position (left-lateral view, right-caudal view). The white circles indicate the locations for the ports; the arrowhead indicates the port in the para-vertebra area; the arrows indicate the port mainly used for laparoscope; B: The arrowhead indicates the port in the para-vertebra area, as seen under the view of laparoscope inside the abdomen. Morrison’s pouch is well-opened in the semi-prone position, with the gravity-assisted movement of the organs, and the port is easily inserted into the area.
