    Notes: 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.

    Initiation of a fibrinolytic system in hepatic resection: The roles of tissue-type plasminogen activator and plasminogen activator inhibitor-1 (1994)

    Notes: Abstract The factors related to the initiation of fibrinolysis, especially with regard to the tissue-type plasminogen activator (tPA) and the plasminogen activator inhibitor-1 (PAI-1), were investigated in 15 patients who underwent hepatic resection, and the findings were compared between those with normal livers and those with diseased livers. It was found that tPA increased before hepatic division, whereas PAI-1 increased after hepatic division and reached a peak immediately following the operation. Plasminogen decreased during hepatectomy, reaching its lowest point on postoperative day 1, and increasing later. Decreased levels of both plasminogen and the α2-plasmin inhibitor were considered to be partly due to plasmin formation in the blood. Patients with a diseased liver tended to have higher intraoperative values of euglobulin lysis activity and higher postoperative values of plasminogen activator, but significantly lower postoperative values of α2-plasmin inhibitor than those with a normal liver. The results of this study suggest that activation of the fibrinolytic system occurs both during hepatectomy and in the early postoperative period, and that patients with a diseased liver are prone to develop hyperfibrinolysis during hepatectomy. Moreover, the increased levels of both tPA and PAI-1 can serve as one of the most sensitive markers for the vital reaction against surgical stress.

    Notes: Abstract We report herein the case of a 59-year-old man found to have adenosquamous carcinoma of the remnant stomach which demonstrated rapid progression. The patient was admitted to our hospital to undergo surgery for a papillary tumor of the remnant stomach. Total resection of the remnant stomach with lymph node dissection was performed, and pathological examination confirmed a diagnosis of adenosquamous carcinoma with invasion into the muscularis propria and lymph node metastasis around the perigastric areas. Multiple liver metastases were found 6 months after the operation, for which a right hepatectomy was performed with curative intent; however, he died 2 months later due to lymphangitis carcinomatosa of the lung.

    Notes: 1 (PGE1) on protecting against hepatic endothelial cell damage and increasing graft viability after cold preservation and reperfusion, using an isolated perfused rat liver (IPRL) model. The grafts were divided into three groups, according to the cold preservation time and PGE1 administration, namely: 4 h preservation (group 1, n = 9), 6 h preservation (group 2, n = 9), and 6 h preservation followed by PGE1 infusion (group 3, n = 9). After cold storage, the grafts were put on the recirculating IPRL system, then reperfused for 120 min at 37°C with oxygenated Krebs-Henseleit buffer containing hyaluronic acid (HA). To examine the function of the sinusoidal endothelial cells and hepatocytes, serial measurements of HA, tumor necrosis factor-α (TNFα), thromboxane B2 (TXB2), acid phosphatase, and conventional parameters in the perfusate were made. After perfusion, the trypan blue exclusion test was performed to assess the presence of any microscopic sinusoidal lining cell damage. In group 3, the bile output and HA clearance were significantly greater, while glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, TNFα, TXB2, and acid phosphatase in the perfusate were significantly lower than in group 2. Histologically, less endothelial cell damage and hepatocyte damage than in group 2 was also confirmed. These results therefore suggest that the improvement of hepatic graft viability by PGE1 administration is mainly due to sinusoidal endothelial cell protection.

    Notes: Abstract To evaluate the benefits of performing laparoscopic cholecystectomy (LC) in patients with cirrhosis, data on 13 patients with liver cirrhosis who underwent cholecystectomy for gallstones between 1989 and 1995 were retrospectively collected from charts filed at Fukuoka City Hospital. These 13 patients were classified into two groups; one, comprised of 7 who underwent LC, and anothe, comprised of 6 who underwent open cholecystectomy (OC). No statistical differences were observed in the duration of surgery or the intraoperative blood loss between the two groups; however, the C-reactive protein (CRP) level in the serum was significantly higher in the OC group than in the LC group. LC was followed by a significantly earlier resumption of a normal diet (P〈0.05) and a shorter hospital stay (P〈0.05) in comparison to OC. All of the patients who underwent OC had an uneventful clinical course; however, one of the patients who underwent LC suffered from intractable ascites postoperatively. The difference in the cost of hospitalization between the two groups was not statistically significant. These findings suggest that the therapeutic significance of performing LC in patients with cirrhosis should be assessdd after carefully evaluating all factors including mortality, morbidity, and cost-effectiveness. Thus, further controlled trials are necessary.

    Notes: Abstract We have developed a visual field quantification system that can accurately quantify the measurement results by the Goldmann Perimeter (GP). This system calculates the plural indexes introduced in published papers. In recent years, several isopter quantification methods have been proposed. In these methods, the isopters are digitized and the data are input into a computer, after which a computer program evaluates the changes in the isopters quantitatively. However, each program is only able to evaluate private indexes. We have developed a system that quantifies data using multiple methods. This system used five methods that have been introduced in published papers. With this system, a physician can analyze GP data with multiple methods and can diagnose diseases accurately. We have already input about 2500 GP recording papers into the computer by this system. We then calculated the plural indexes, and visualized the temporal changes in the perimetry.

    Notes: Abstract In literature database searching, we show that it is necessary to use plural databases for a more improved search. We also compare the results of a single database search with that of multiple database search in the domain of Japanese life sciences. We searched the MEDLINE and EMBASE using the same search terms. There were some differences in the results, owing to differences in the journals and recording methods. We herein show some of the differences in the journals contained in both databases. Furthermore, we show the differences in the number of papers derived from the same journal. Next, as an example of a practical search, we selected some universities in Japan, searched both databases regarding papers published from these universities and then merged the results by hand. According to our results, only 63% of all papers were common to both databases.

    Notes: Abstract A simple outpatient follow-up system was developed with a laptop personal computer to assist management of patients with hepatocellular carcinoma after hepatic resections. Since it is based on a non-relational database program and the graphical user interface of Macintosh operating system, those who are not a specialist of the computer operation can use it. It is helpful to promptly recognize current status and problems of the patients, to diagnose recurrences of the disease and to prevent lost from follow-up cases. A portability of the computer also facilitates utilization of these data everywhere, such as in clinical conferences and laboratories.
