Excision of tissue during a hepatectomy (surgical resection of the liver). In this case, a secondary hepatic deposit from a previously removed colonic cancer is being excised. Hepatectomy is used to remove benign or malignant neoplasm (abnormal tissue growth) in the liver, malignant neoplasms commonly being metastases of colorectal cancers. The surgeon is using a cavitron ultrasonic surgical aspirator, an instrument that reduces blood loss.
