    Notizen: Abstract Portal pressures were estimated non-invasively in 100 patients who underwent hepatic resection and completely fulfilled the 21 variables evaluated. Ten variables were selected from among all those in the univariate analysis, and a stepwise discriminant analysis revealed four independent significant variables, namely: The indocyanine green dye retention test at 15 min (ICGR15); the prothrombin time index; the platelet count; and the globulin fraction. An equation to estimate the portal pressure was made using the coefficients in the analysis, the reliability of which was confirmed (r=0.70484,P=0.0001). The univariate analysis revealed ten significant variables to discriminate portal hypertension, defined as a portal pressure of over 200 mmH2O. A multiple logistic regression analysis of these variables revealed two independent variables, being ICGR15 and the platelet count. Thus, we consider that our equation for estimating portal pressure is potentially useful, and that the platelet count and ICGR15 are the most significant parameters in discriminating between the presence or absence of portal hypertension. Moreover, a platelet count of less than 120×103/mm3 and an ICGR15 value of more than 15% correlated well with portal hypertension.

    Notizen: Abstract We present herein the case of a sclerosing hemangioma of the liver which was extremely difficult to differentiate from liver metastasis of rectal cancer, in a 67-year-old woman. All the radiological findings were compatible with liver metastasis; however, marginal pooling of the tumor revealed by computed tomographic angiography and magnetic resonance imaging scans was inconsistent with a diagnosis of liver metastasis. At laparotomy, the tumor was macroscopically unusual in that it was yellowish elastic-hard with a very clear margin, and thus, it did not have the appearance of a metastatic tumor. Mile's operation and a partial hepatectomy were performed, followed by an uneventful postoperative course and no signs of recurrence. The carcinoembryonic antigen (CEA) level in the peripheral blood was not elevated at any time. The postoperative pathological diagnosis was a rare hepatic tumor, namely, a "sclerosing hemangioma," based on the findings of cellular fibrous stroma containing vascular channels with flattened endothelial cells. Preoperatively differentiating between sclerosing hemangioma and a metastatic liver tumor from colorectal cancer may be very difficult; however, this case demonstrated some interesting characteristics, namely, the serum CEA level was not elevated, marginal pooling of the tumor was found in the enhanced radiological findings, and the tumor was macroscopically unusual. Therefore, the possibility of sclerosing hemangioma should be borne in mind when considering the differential diagnosis of patients suspected of having colorectal liver metastasis. A preoperative biopsy should be carried out and when a laparotomy is performed under the misdiagnosis of colorectal liver metastasis, it is advisable that either an intraoperative needle biopsy or a frozen histological analysis be undertaken to avoid unnecessary extended hepatic resection of this rare benign hepatic tumor.

    Notizen: Abstract The regenerative capacity of the liver was assessed using a volumetric method on computed tomography in 21 adults: 16 underwent a standard right hepatic lobectomy for hepatocellular carcinoma, there were hepatic metastases in 3 others, and 2 suffered from other diseases. The patients' ages ranged from 33 to 68 years with a mean age of 57.0 years. The regeneration rate was expressed as the rate of the volume increase of the remnant left lobe compared with the preoperative volume of the left lobe. A univariate regression analysis showed that the portal pressure had a highly inverse correlation with the regeneration rate of the liver (r = −0.4753,P = 0.0397), while a multiple regression analysis demonstrated the correlation between the portal pressure, age, and the regeneration rate (multipler = 0.5640). The regeneration rate of the normal liver (97.6 ± 53.5%) was significantly higher than that of the chronic hepatitic (43.0 ± 40.7%), and also tended to be higher than that of the cirrhotic liver (51.5 ± 13.2%). However, there were no differences between chronic hepatitic and cirrhotic livers. The portal pressure before hepatectomy of the normal liver (149 ± 19 mmH2O) was significantly lower than those of chronic hepatitic (188 ± 38 mmH2O) and cirrhotic (245 ±78 mmH2O) livers. We thus conclude that the regenerative capacity of the liver following a right hepatic lobectomy could be estimated on the basis of both portal pressure and age. The regenerative capacity was also influenced by underlying liver diseases.
