(a) One transumbilical access port is created for videolaparoscopy and working trocars are inserted into four other ports. A Nathanson hook liver retractor is placed in the subxiphoid location (arrow). (b) Intraoperative photograph of Case 3 showing that the stomach and lateral segment of the liver are retracted by the retractor. The cystic tumor (arrowhead) is exposed optimally even if the omental branches of the left gastroepiploic vessels remain (arrow). (c) Schema of laparoscopic SPDP-VRes. The pancreas is divided at the dissection line (dotted line). The splenic vein is divided at the proximal side of tumor and the pancreatic tail (solid line), preserving the confluence of the SGV, the LGEV and the LOB. The three drainage routes from the spleen are indicated by the blue dotted arrows: the arcade of the GEV; the arcade of the omental vein and the SGV to the LGV via the stomach wall. PV: portal vein, SMV: superior mesenteric vein, SpV: splenic vein, SpA: splenic artery, T: tumor.
