OUTLINE: Patients who have undergone routine clinical staging (CT scan, angiogram, etc.) and who have been classified as potentially resectable undergo laparoscopy and laparoscopic ultrasound (L+LUS). At the end of the L+LUS, based on the new findings patients are reclassified as either potentially resectable or potentially unresectable. All patient then undergo definitive staging: those who have metastasis to the liver that can be pathologically confirmed by biopsy at the time of the laparoscopy are classified as unresectable and do not undergo laparotomy; all others undergo laparotomy and then are classified as resectable or unresectable. If 8 or more patients are misclassified at the time of the L+LUS, then this study is terminated.
