Techniques of Liver Resection
Tissue link sealant systems
In this instrument, saline runs to the tip of the electrode to couple RF energy to the liver surface and achieve coagulation
Radiofrequency
In this technique, a Cool-tip RF electrode (Radionics Inc., Burlington, MA, USA) is inserted along the transection plane serially 1–2 cm apart, and RF energy is applied for 1–2 min to create overlapping cylinders of coagulated tissue, followed by transection of the coagulated liver using a simple scalpel. In a preliminary study of 15 cases of mainly segmental or wedge resection reported by Weber et al. , the mean blood loss was only 30±10 ml, and no complications such as bile leakage were observed
