Most problems encountered in the Department of Hepatobiliary Surgery were centered around the bleeding of the liver and uncontrolled blood loss. Hence, the specialties of the department were bleeding control and hepatectomy. These were the skills all the doctors in the department spent their days practicing and studying.
There were many surgical approaches to hepatectomy: the pringle maneuver, using a scalpel, using microwaves, using lasers, the water-jet method...
In reality, surgeons had tried using various instruments a person could find in the operating theater to carry out hepatectomies, such as suction machines, hemostatic forceps, scalpels, and other instruments. It was as if they simply lifted those livers and tried all means and methods to chop parts off them.
You could only imagine how anxious a doctor performing hepatectomy for the first time would feel.
