“…Bleeding can obscure views, making surgery difficult, and the loss of manual compression can make surgery harder to control, occasionally necessitating conversion to open procedure [9]. In addition, major bleeding from hepatic veins can be associated with gas embolism, especially in a high intraabdominal pressure setting [10][11][12], and any blood loss necessitating transfusion increases the risk of postoperative morbidity, mortality [13][14][15], and tumor recurrence [16,17]. Therefore, familiarity with the various hemostatic methods, techniques, and tools is an essential requirement for all laparoscopic surgeons, and their continuing development is important for the safe expansion of this surgical approach.…”
