Diversify minimally invasive ablation treatment to improve the efficacy of minimally invasive surgery for liver cancer: Asia? The center that has completed the most argon helium knife cryoablation treatment for liver tumors, carries out argon helium knife cryoablation treatment with the combination of ultrasound, CT, MRI and other guidance modalities, in addition to local ablation treatment methods that combine radiofrequency, microwave, anhydrous alcohol injection and other ablation modalities, which not only maximizes the solution to problems such as post-operative bleeding after local ablation, thus increasing the influence of the center in the field of minimally invasive ablation and The efficacy of ablation treatment is improved to meet the needs of more patients. New local minimally invasive ablation treatment technologies, such as NanoKnife, have been approved by the Chinese FDA in the first half of 2015, and related clinical procedures have been carried out in several hospitals in China. The treatment uses modern imaging to guide the high-frequency nanoknife into the tumor lesion, releasing nanoparticles to kill tumor cells with minimal damage to surrounding blood vessels, bile ducts and other normal tissues, and is suitable for tumor tissues in the hilar region and near the bile ducts. The center intends to conduct technical collaboration with NanoKnife to explore the experience of NanoKnife treatment for patients with refractory liver cancer. Standardize the preoperative, intraoperative and postoperative management system of minimally invasive ablation treatment to enhance the treatment effect and reduce complications: Preoperative discussion of minimally invasive ablation (including the surgical approach, the scope of ablation of the target lesion, the puncture path, the scope of destruction of the target lesion and the expected target to be achieved) to ensure that the preoperative surgeon has good communication and exchange with the patient and family members; to the surgeon, the bedside doctor and the doctor on duty for minimally invasive treatment The standardized management of the postoperative system ensures the provision of quality services to patients and greatly reduces the occurrence of ablation complications.
