Abstract

Purpose: The aim of this study was to compare helical CTAP and helical CT-scan in the preoperative assessment of liver metastases.

Methods: A prospective unicentric study in 12 patients was performed with helical CTAP and helical CT-scan. All patients underwent partial hepatectomy with intraoperative palpation and sonography within 19 days (mean: 9 days).

Results: Examination of resected liver specimens found 38 metastases, from colorectal cancer in 36 cases. The sensitivity was 92.1% for helical CTAP and 79% for helical CT-scan. This sensitivity was 85% for helical CTAP and 60% for helical CT-scan for nodules 1 cm or less in diameter (P = 0.08).

Conclusion: In the preoperative screening of liver metastases, helical CT-scan should be performed as the first choice examination. When hepatic lesions seem to be curable by resection based on helical dynamic CT-scan results, helical CTAP should be performed to increase the sensitivity of detection of lesions 1 cm or less in diameter.
