The abdominal cavity is carefully inspected for evidence of pinpoint or large metastases in the pouch of Douglas, colon, mesentery, small bowel, omentum, or peritoneum. Any suspicious areas are excised for frozen section examination. The liver surface is inspected for evidence of metastases, followed by bimanual palpation to verify the diagnostic procedures suggesting metastasis in the left lobe of the liver. Metastases deep within the left lobe rather than superficially are best evaluated with a hand-held ultrasound probe. Metastases readily seen on the surface of the left lobe can be locally excised with a 1-cm margin. Metastases near the inferior liver margin can be removed by wedge incision.
