BACKGROUND: Major hurdles for laparoscopic right hepatectomy (LapRH) include difficulties in (1) mobilization and (2) applying hanging maneuver and (3) lack of experienced assistants. We discuss the protocolization of lapRH, introducing our simplified technique. METHODS: The procedure was disassembled into six steps: (1) curtailed mobilization of the right liver so as to align the resection plane with the laparoscopic camera view, (2) inflow vascular control, (3) setting up the parenchymal resection applying the rubber band retraction method, (4) parenchymal resection approaching the caudate lobe, (5) a lifting-up maneuver using a laparoscopic grasper or retractor instead of the hanging maneuver, and (6) completion of resection dividing the caudate lobe, right hepatic vein, and remaining ligament...

BACKGROUND: To better understand the role of acute normovolemic hemodilution (ANH) in a surgical setting with high risk of bleeding, we analyzed all randomized controlled trials (RCTs) in the setting of cardiac surgery that compared ANH with standard intraoperative care. The aim was to assess the incidence of ANH-related number of allogeneic red blood cell units (RBCu) transfused. Secondary outcomes included the rate of allogeneic blood transfusion and estimated total blood loss. METHODS: Twenty-nine RCTs for a total of 2439 patients (1252 patients in the ANH group and 1187 in the control group) were included in our meta-analysis using PubMed/MEDLINE, Cochrane Controlled Trials Register, and EMBASE...
