Laparoscopic versus Open Liver Resection: Differences in Intraoperative and Early Postoperative Outcome among Cirrhotic Patients with Hepatocellular Carcinoma—A Retrospective Observational Study

Table 3

Intraoperative respiratory and metabolic parameters, transfusions, and operative time divided in two groups according to type of surgical approach; RBC: red blood cells; FFP: fresh frozen plasma; PT RBC/FFP: patients transfused with units of RBC/FFP.
