Precision liver surgery: 【ICG Fluorescence Imaging-guided Minimally Invasive Surgery for Liver Cancer】
With the vast advances of science and technology, minimally invasive surgery featuring minor wounds and less blood loss has gradually replaced open liver surgery in many cases. In order to locate positions of liver tumors more accurately, we also introduced ICG Fluorescence Imaging system that helps surgeons perform liver resections precisely and completely. In our hospital, there are three ways of using ICG Fluorescence Imaging depending on different positions of tumors. First, when a tumor is on liver surface, a surgeon will use endoscopic ICG system to identify and remove a tumor directly since tumors naturally absorb more ICG than other tissues. Second, for minor but deep-seated tumors, liver resection is performed after segmental hepatic artery or portal vein is given the ICG injection. Third, if a liver tumor is larger and has occupied two segments, surgeons could cut off its dominant vessels, inject ICG into hand veins, and resect the part without fluorescence imaging. The following is the one of the most common cases using the first way we mentioned above.
A 47-year-old male with Hepatitis B has been under treatment and followed for six years and has become HBsAg negative afterward. However, he was diagnosed as hepatic cancer with a 1.3 cm tumor after an ultrasound scan last September. We decided to have the patient undergo minimally invasive surgery using ICG fluorescence imaging system, which assisted us to see the position of the tumor clearly and perform liver resection precisely. The blood loss of the operation was merely 10 cc, and the tumor was entirely removed. Most of all, the patient could have meals normally and move about with ease on the very first day after surgery.
