    Description / Table of Contents: Résumé Vingt-deux patients cirrhotiques ayant un carcinome hépatocellulaire associé à des varices esophagiennes ont eu une résection hépatique aggressive associée à une dévascularisation et/ou à une sclérothérapie endoscopique périopératoire (groupe A). Les résultats ont été comparés à ceux de 37 patients cirrhotiques sans varices oesophagiennes qui ont eu une résection hépatique pour un carcinome 〈 2 cm pendant la même période (groupe B). Ont été étudiés les données cliniques, paracliniques préopératoires, l'aspect anatomopathologique, la survie globale et la survie sans maladie. La durée de l'opération, la quantité de sang perdu et le poids du foie réséqué ne différaient pas, alors que la taille de la tumeur dans le groupe A (2.7±1.6 cm, moyenne±ET) était significativement plus importante que dans le groupe B (1.5±0.3 cm). La fonction hépatique préopératoire était plus perturbée dans le groupe A par rapport au groupe B exception faite pour le temps de prothrombine. En dépit de ces inconvénients, les taux de survie sans maladie à 1, 3 et 5 ans des groupes A étaient respectivement de 72% et 94%, 48% et 54%, et 38% et 45% par rapport au groupe B, repsectivement. Les taux de survie globale étaient respectivement de 91% et 97%, 79% et 79% et 54% et 67%, sans différence significative, dans les groups A et B. Aucun malade dans le groupe A n'a saigné après traitement. Sur ces données, la résection hépatique aggressive associée à une dévasculatisation simultanée ou une sclérothérapie endoscopique périopératoire est le traitement de choix pour un carcinome hépatocellulaire associé à des varices oesophagiennes.
    Abstract: Resumen Veintidós pacientes con carcinoma hepatocelular (CHC) y várices esofágicas concomitantes fueron sometidos a resección hepática acompañada de devascularización y/o escleroterapia endoscópica perioperatoria (grupo A). Con el propósito de evaluar esta modalidad de tratamiento, se estudiaron también 37 pacientes cirróticos sin varices esofágicas que fueron sometidos a resección hepática por CHC pequeño, de 2 cm o menos, en la misma época (grupo B), comparando datos preoperatorios, hallazgos anatomopatológicos, tasas de evolución libre de enfermedad y tasas de sobrevida. El tiempo operatorio, la magnitud de la pérdida de sangre y el peso del hígado resecado no mostraron diferencias entre los dos grupos; sin embargo, el tamaño del tumor en el grupo A (2.7±1.6 cm) fue significativamente mayor que en el grupo B (1.5±0.3 cm). La alteración de la función hepática en el grupo A apareció más pronunciada que en el grupo B, excepto por el tiempo de protrombina. A pesar de estas ventajas, las tasas de evolución a uno, tres y cinco años en los dos grupos fueron 91% vs 97%, 79% vs 79% y 54% vs 67% (grupo A vs grupo B) respectivamente, cifras que no representan diferencia significativa. Además, no se encontró sangrado varicoso en el grupo A después del tratamiento. Con base en taies hallazgos, se plantea que el tratamiento de elección en los pacientes con CHC y várices esofágicas concomitantes es la resección agresiva combinada con devascularización simultánea y/o escleroterapia endoscópica perioperatoria.
    Notes: Abstract Twenty-two cirrhotic patients with hepatocellular carcinoma (HCC) and concomitant esophageal varices underwent aggressive hepatic resection accompanied by simultaneous devascularization, perioperative endoscopic injection sclerotherapy, or both (group A). To evaluate this treatment, 37 cirrhotic patients without esophageal varices who underwent hepatic resection for small HCC (2 cm or less) during the same period (group B) were studied to compare clinical data, preoperative laboratory data, pathologic findings, disease-free rates, and survival rates. The operative time, blood loss, and resected liver weight did not differ between the two groups; however, the tumor size of group A (2.7±1.6 cm, mean±SD) was significantly larger than that of group B (1.5±0.3 cm). The preoperative liver function of group A was also more severe than that of group B except for prothrombin time. Despite these disadvantages, the 1-, 3-, and 5-year disease-free rates of the two groups were 72% versus 94%, 48% versus 54%, and 38% versus 45%, respectively, and the 1-, 3-, and 5-year survival rates were 91% versus 97%, 79% versus 79%, and 54% versus 67% (group A versus group B), respectively, which showed no significant differences. Furthermore, there was no variceal bleeding in group A after treatment. Based on the above findings, for treatment of HCC and concomitant esophageal varices, aggressive hepatic resection accompanied by simultaneous devascularization, perioperative endoscopic injection sclerotherapy, or both is the preferred form of treatment.

    Notes: Abstract In spite of the improved outcome of orthotopic liver transplantation (OLTx), primary graft nonfunction remains one of the life-threatening problems following OLTx. The purpose of this study was to evaluate plasma lecithin: cholesterol acyltransferase (LCAT) activity in multiple organ donors as a predictor of liver allograft viability prior to OLTx. Thirty-nine donors were studied during a 5-month period between April and August 1988. Allograft hepatectomy was performed using a rapid technique or its minor modification with hilar dissections, and the allografts were stored cold (4°C) in University of Wisconsin (UW) solution. Early post-transplant allograft function was classified as good, fair, or poor, according to the highest SGOT, SGPT, and prothrombin time within 5 days following OLTx. Procurement records were reviewed to identify donor data, which included conventional liver function tests, duration of hospital stay, history of cardiac arrest, and graft ischemic time. Blood samples from the donors were drawn immediately prior to aortic crossclamp, and from these plasma LCAT activity was determined. Plasma LCAT activity of all donors was significantly lower than that of healthy controls (12.4±8.0 vs 39.2±13.3 μg/ml per hour, P〈0.01). LCAT activity (16.4±8.3 μg/ml per hour) in donors of grafts with good function was significantly higher than that in those with fair (8.6±4.5 μg/ml per hour, P〈0.01) or poor (7.3±2.4 μg/ml per hour, P〈0.01) function. Information regarding procurement, which was complete in the records of 31 of 39 donors, was used in a multiple logistic regression analysis that revealed plasma LCAT activity to be the only factor able to discriminate the quality of the hepatic graft from other variables in multiple organ donors. The present study suggests that the determination of plasma LCAT activity in multiple organ donors is extremely useful for the assessment of hepatic allograft viability prior to OLTx.

    Notes: Abstract For the assessment of graft viability, serum hyaluronic acid (HA) levels during porcine orthotopic liver transplantation were measured in two groups: group 1 (viable:n = 5) in which allografts were transplanted following a minimal cold (4°C) preservation, and group 2 (nonviable:n = 4) in which allografts were transplanted after cold static storage (4°C) for 24 h in University of Wisconsin solution. The changes in the HA levels reached a significant difference between the two groups at 30 min after reperfusion (P 〈 0.02). In group 1, all animals survived for over 4 days, while all animals in group 2 died within 24 h. The serum HA also demonstrated a significant correlation with prothrombin time, ß-glucuronidase, and aspartate aminotransferase at 120 min after reperfusion. These results suggest that the measurement of serum HA is a potentially effective index for evaluating hepatic allograft viability.

    Notes: Abstract We describe herein the case of a 57-year-old man with thalassemia who developed acute liver failure after undergoing endoscopic injection sclerotherapy (EIS) to control hemorrhage from a ruptured esophageal varix. The patient, who had been comfirmed as having liver cirrhosis due to chronic hepatitis C with thalassemia in 1989, was admitted to our department to undergo EIS for esophageal varices, at which time his serum total bilirubin level was 5.5 mg/dl. As a small amount of hematemesis occurred just after a percutaneous transhepatic portography was performed, emergency EIS was carried out, following which the serum total bilirubin level markedly increased, mainly with a direct fraction, until it reached 70 mg/dl. The patient eventually died from acute liver failure with extreme hyperbilrubinemia on the 27th day after experiencing hematemesis despite all treatment. This unfortunate case demonstrates that sclerotherapy could be an inappropriate method of treatment for patients with hemolytic disease.

    Notes: Abstract To analyze the relationship between the development of postoperative delirium and a change of the patient's room, 1,006 cases of patients who had undergone surgery with general anesthesia were reviewed. Postoperative delirium developed in 84 (8.3%) cases. On the basis of symptomatic features, postoperative delirium was divided into four types: (1) excitement type, (2) excitement-hallucination type, (3) hallucination type, and (4) disorientation type. Of the 31 excitement-type cases, 21 developed within the 2nd postoperative day (POD) while 27 of 29 hallucination types developed after POD 2. Of 29 hallucination types, 22 developed after a room change while 20 of these 22 cases were transferred to a single room before POD 2. A quiet, dark, and isolated environment in a single room is suggested to contribute to the development of hallucinations. The development of postoperative delirium with hallucinations alone should thus be taken into consideration whenever a room change is decided.
