The purpose of this study is to compare the accuracy of liver segmentation between positive and negative staining during laparoscopic liver resection in order to achieve precise anatomic resection such as segmentectomy based on preoperative planning. Furthermore, long-term outcomes can be future research of such precise anatomic resection.
Efficacy
To determine the ability of the guidance in anatomic resection, the primary endpoint is the success rate of the ICG staining which consists of a subjective optical scoring based on three components: superficial demarcation in the liver surface, visualization of parenchymal borders, and consistency with the preoperative three-dimensional (3D) simulation. The resection margin and the shape/weight of the specimen in comparison with the pre- and post-operative 3D simulations of the liver will be evaluated as well.

Negative staining group:
At the early phase during the surgery, extrahepatic (extrafascial) Glissonean approach is performed to encircle the target Glissonean pedicle feeding the tumorous area exactly corresponded to the preoperative simulation. Sequentially, the inflow blockage is confirmed by using laparoscopic intraoperative ultrasonography (IOUS) with doppler mode. Since the staining is irreversible after the ICG injection, 0.15ml/kg of ultrasound contrast medium (SONAZOID, Daiichi-Sankyo, Tokyo, Japan) are systematically injected prior to ICG injection. If the target area is correctly in cyanosis, 0.5 mg/body of ICG is intravenously injected for ICG negative staining method. As for near-infrared camera system, 1688 Advanced Imaging Modalities Platform (Stryker Co., MI, USA) was used for all cases.The liver transection is performed using CUSA and other energy devices.
Positive staining group:
The portal branches of tumor-bearing liver segments are targeted and punctured under ultrasound guidance with an 18- or 21- gauge needle introduced through the abdominal wall. The direction of the needle is assisted by the needle hole in a dedicated laparoscopic ultrasound probe (provided by BK Medical, Herlev, Denmark). Subsequently, a small amount of ICG (determined in the pilot study) is injected into the portal branch slowly for avoiding the risk of ICG retrograde flow into neighboring segments. The liver transection will be performed using CUSA and other energy devices.

Male and Female
The inclusion criteria are as follows: male or female patients with primary or metastatic liver tumors, 20 years or older, scheduled for elective LLR, preserved liver function, able to understand the nature of the study, and willing to join and give voluntary written consent. Liver functional reserve will be evaluated by serum biochemical tests (albumin level, total bilirubin level and prothrombin time) and ICG retention rate at 15 minutes (ICG-15R). The severity of liver function is assessed based on Child-Pugh stages and the liver damage classification defined by the Liver Cancer Study Group of Japan.15 Preserved liver function is defined as an ICG-15R less than 15% and a Child-Pugh classification A or B.
The exclusion criteria are as follows: repeat liver resection, tumor in segment 1, severe liver or renal insufficiency, ICG hypersensitivity, pregnant or breastfeeding, or unable to understand the nature of the study or refuse it.
