As a new screening procedure, intraoperative ultrasonography using high-resolution real-time instruments was used routinely in 84 colorectal cancer operations to scan the entire liver for liver metastases. In 10 operations (11.9%), intraoperative ultrasonography identified 14 previously unrecognized metastatic tumors, all of which were less than 2 cm in size and were nonpalpable. The sensitivity of this technique in detecting metastatic liver lesions (97.8%) was significantly superior (p less… CONTINUE READING
