99m Tc-mebrofenin hepatobiliary scintigraphy with SPECT/CT (HBS-M) has become an important quantitative method to evaluate global liver function and future liver remnant (FLR) function in patients who are candidates for resective liver surgery. The purpose of this work was to describe the method in the prediction of post-surgical liver failure. The overall liver function and that of the FLR are obtained by analysis of the initial dynamic phase of the scan. Liver volume to be preserved is expressed as a percentage of the total liver volume measured in both CT sections...

BACKGROUND: Resection of liver-isolated metastases of colorectal cancer (CRC) offers the greatest likelihood of cure. Nevertheless, recurrence rates after this procedure are high, and chemotherapy is a reasonable choice with inconclusive evidence. We aimed to determine if there is a survival difference between patients receiving systemic therapy with surgery versus surgery alone for resection of liver metastases. METHODS: From a source population of 170 patients treated in our National Centre (Centro Nacional de Cirugía Hepatobiliar, San José, Costa Rica), with liver metastases from various primary sites, we selected 51 patients with CRC who underwent hepatic resection with curative intent...

The diagnostic values of CA 19-9 and CEA were evaluated in 187 cases (including 31 gastric, 41 colorectal, 12 pancreatic, 7 hepatobiliar and 5 hepatocellular carcinomas). These tumor markers were compared to the other laboratory parameters [hemoglobin, erythrocyte sedimentation rate, serum bilirubin, ASAT (aspartate amino transferase), ALAT (alanine amino transferase) GGT (gamma glutamil transpeptidase), ALP (alkaline phosphatase)]. The specificity of CA 19-9 was 89.5%, while the sensitivity of this tumor markers was 91...
