The Application of Laparoscopic B-Ultrasound Microwave Ablation Technology in Liver Metastasis of Colorectal Cancer

Liver is the most common metastasis target organ in the late stage of colorectal cancer. More than 50% of colorectal cancer patients will have simultaneous or heterochronous liver metastasis. The survival time of patients with colorectal cancer and liver metastasis (CRLM) is short; not all patients can get radical resection of liver metastasis. For this part of patients, microwave ablation technology has been proved to be one of the effective methods for the treatment of liver metastasis. Laparoscopic B-ultrasound ablation also highlights a lot of minimally invasive advantages; this paper reviews the relevant literature of PubMed database, Wanfang database and CNKI database, in order to provide the treatment basis for clinical application of microwave ablation technology under laparoscopic B-ultrasound in the treatment of CRLM. The results showed that the safety and effectiveness of microwave ablation for liver metastases under the location of B-ultrasonic laparoscopy were confirmed, and patients with liver metastases of colorectal cancer who could not be resected could choose this treatment.
