Correct Answer: Perform a right hemicolectomy and a wedge resection of metastasis
Description: Because approximately 5% of colorectal cancers are associated with resectable hepatic metastases, appropriate preoperative- discussion should include obtaining permission for removal of synchronous peripheral hepatic lesions if they are found. If gross tumor is removed, a 25% cure rate can be anticipated. Adequate local resection, either by wedge or by limited partial hepatectomy, may be carried out whenever no extrahepatic disease is found and the hepatic lesion is technically removable. Any option that leaves the potentially obstructing primary cancer unremoved would be unacceptable.
