Preoperative evaluation of patients for liver resection. Appropriate CT imaging.

Abstract:

OBJECTIVE:The authors determined which combination of computed tomography scans is most helpful for preoperative assessment of patients with liver tumors. SUMMARY BACKGROUND DATA:Multi-institutional studies have shown that the most important prognostic factors for selection of patients with metastatic colorectal cancer considered for liver resection are: Dukes' stage of primary tumor, the number of hepatic metastases if greater than 3, the presence of extrahepatic cancer, and the ability to resect tumors with an adequate margin (> 1 cm.) Therefore the ability to predict the presence of extrahepatic disease and the number and location of hepatic tumors are important in these patients. METHODS:One hundred and nine consecutive patients with evidence of hepatic tumors were evaluated by computed tomography with arterial portography (CTAP) and abdominal computed tomography after a 4-hour delay (CT-D). Results of these studies and conventional computed tomography (CT-C) were compared with findings at operation. RESULTS:CTAP proved to be the most sensitive test for assessing distribution of intrahepatic disease. CT-D was no more sensitive than CT-C for the detection of hepatic or extrahepatic disease. CONCLUSIONS:CT-C in concert with CTAP provides the most reasonable CT evaluation of patients considered for operation for the treatment of hepatic tumors.
