In the primary treatment of colorectal cancer, staging laparoscopy is seldom used since surgical resection and palliation are typically indicated to prevent bleeding, obstruction, and perforation even in patients with advanced disease. However, patients who have liver metastases from a primary colorectal cancer may be candidates for curative resection when there is no other extrahepatic disease, and when all of the disease in the liver is resectable. Thus, staging laparoscopy for these patients can provide more accurate identification of all hepatic lesions, including size,
number, and location, than non-invasive imaging. Staging laparoscopy may also be indicated in potentially convertible liver metastasis after few cycles of chemotherapy
