The Effects of Laparoscopic Liver Resection on Cardiopulmonary Performance

This video was part of the Video Loop during the SAGES 2020 Virtual Meeting. Topic: Miscellaneous / Other. The Effects of Laparoscopic Liver Resection on Cardiopulmonary Performance. Morgan Bonds, MD, Russell Kirks, MD, James Helman, MD, Adnan Alseidi, MD. Virginia Mason. Medical Center.

This video examines the effects of laparoscopic liver resection on cardiopulmonary performance. Increased insufflation pressures are used during laparoscopic liver resection to decrease bleeding from hepatic veins. It is anticipated that these increased intra-abdominal pressures would result in decreased preload with compensatory tachycardia. There is also concern that a hole in the hepatic vein may result in carbon dioxide embolus with these elevated pressures. The video demonstrates the effect of different insufflation pressures on transesophageal echocardiogram measurements in real time during liver parenchymal transection.
