    Description / Table of Contents: Résumé Pour étudier les causes d'insuffisance hépatocellulaire postopératoire chez le cirrhotique ayant eu une résection hépatique pour carcinome hépatocellulaire, nous avons analysé les données chez 126 patients cirrhotiques opérés entre 1977 et 1987. On a revu les dossiers de 102 patients ayant eu une évolution postopératoire satisfaisante (groupe de survie) et de 24 patients qui ont développé une insuffisance hépatique et qui en sont morts (groupe d'insuffisance hépatocellulaire). On n'a pas pu mettre en évidence de différence de fonction hépatique préopératoire entre les 2 groupes. Du point de vue histologique, l'inflammation était modérée ou sévère chez 20 (83%) des 24 patients du 2e groupe. On a pratiqué des résections majeures (hépatectomies et hépatectomies élargies) plus nombreuses dans ce groupe. La perte sanguine périopératoire moyenne était de 1,945 et 4,322 g, respectivement, dans le groupe de survie et dans celui d'insuffisance hépatocellulaire. Cette différence est statistiquement significative (p 〈 0.01). On a observé des complications majeures chez 22 (22%) des 102 patients dans le groupe des survivants. On a observé des complications majeures suivies d'insuffisance hépatique chez 21 (88%) des 24 patients dans le deuxième groupe, cette différence étant hautement significative (p 〈 0.001). A la lumière de ces faits, nous proposons: (a) de faire une biopsie hépatique avant toute résection, (b) de limiter les pertes sanguines à 2000 g, et (c) d'administrer en période postopératoire les soins intensifs nécessaires pour éviter les complications susceptibles de provoquer l'insuffisance hépatique.
    Abstract: Resumen Con el propósito de elucidar la causa de la falla hepática postoperatoria en los pacientes cirróticos sometidos a resección por carcinoma hepatocelular, hemos analizado la información clínica correspondiente a 126 cirróticos tratados quirúrgicamente entre 1977 y 1987. Se revisaron las historias clínicas de 102 pacientes que tuvieron una buena evolución postoperatoria (grupo de sobrevivientes) y de 24 que desarrollaron falla hepática y murieron (grupo de falla hepática). No se encontró diferencia aparente en cuanto al estado preoperatorio de la función hepática entre los 2 grupos. Desde el punto de vista histológico, se halló actividad inflamatoria de grado moderado a severo en el hígado de 20 (83%) de los 24 pacientes del grupo de falla hepática. Las resecciones mayores (lobectomía y lobectomía ampliada) fueron más frecuentes en el grupo de falla hepática. El promedio de pérdida perioperatoria de sangre fue de 1,945 g y 4,322 g en los grupos de sobrevivientes y de falla hepática, respectivamente, lo cual représenta una diferencia significativa (p 〈 0.01). Complicaciones postoperatorias mayores se presentaron en 22 (22%) de los 102 pacientes del grupo de sobrevivientes, en tanto que las complicaciones mayores seguidas de falla hepática ocurrieron en 21 (88%) de los 24 pacientes del grupo de falla hepática, diferencia que es significativa (p 〈 0.001). Con base en estos datos hacemos las siguientes recomendaciones: (a) se debe realizar un examen histológico antes de emprender la resección, (b) la pérdida perioperatoria de sangre debe limitarse a menos de 2,000 g, (c) el cuidado intensivo postoperatorio es necesario para prévenir complicaciones que puedan dar lugar a falla hepática.
    Notes: Abstract To study the causes of postoperative hepatic failure in cirrhotic patients undergoing resection for hepatocellular carcinoma, we evaluated data on 126 cirrhotic patients surgically treated from 1977 to 1987. The records of 102 patients with a good postoperative course (survival group) and 24 patients who developed hepatic failure and died (hepatic failure group) were reviewed. No difference in preoperative liver function was apparent between the 2 groups. Histologically, moderate to severe inflammatory activity in the liver was present in 20 (83%) of 24 patients in the hepatic failure group. Major hepatic resections (lobectomy and extended lobectomy) were more frequent in the hepatic failure group. Mean perioperative blood loss was 1,945 g and 4,322 g in the survival and hepatic failure groups, respectively, with a significant difference (p 〈 0.01). Major postoperative complications occurred in 22 (22%) of 102 patients in the survival group and major complications followed by hepatic failure occurred in 21 (88%) of 24 patients in the hepatic failure group, with a significant difference (p 〈 0.001). In light of these data, we propose that: (a) histological examination should be done before the resection, (b) perioperative blood loss should be less than 2,000 g, and (c) intensive care is needed postoperatively to prevent complications which might lead to hepatic failure.

    Notes: Abstract The indications for liver resection performed in 18 patients with cavernous hemangioma of the liver at the Second Department of Surgery, Kyushu University Hospital, from 1985 to 1993, were reevaluated. The mean age of the patients was 49.7 years. Two patients had abdominal pain and 3 had gastric symptoms. Hepatocellular carcinoma could not be ruled out in 4 patients. None of the other patients had any clinical manifestations other than detection of the tumor. The average size of the tumors was 7.8cm (range 1–21 cm). In all, five partial resections, three subsegmentectomies, seven segmentectomies, and three bisegmentectomies of the liver were performed. No severe complications were encountered postoperatively, and no recurrences were found after the operation. A review of the literature revealed that spontaneous rupture of such tumors is infrequent. It therefore seems that there was no indications for surgery in our patients, except for the 4 in whom hepatocellular carcinoma could not be ruled out. Although elective liver resection for cavernous hemangioma is safe, the indications for surgery should be more narrowly defined in the future.

    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.

    Notes: Abstract We report eight cirrhotic patients with liver cancer of less than 2 cm in diameter, and who were successfully treated by surgery. The sensitivities of diagnostic procedures for small lesions showed that alpha-fetoprotein (AFP) was 75 per cent, radionuclide scanning 25 per cent, CT 33 per cent, ultrasonography 40 per cent and angiography 88 per cent. Serial measurement of AFP appears to be the most helpful for detection of hepatocellular carcinoma at the early stage, particularly in cirrhotic patients. Although hepatic imagings are of limited value for small hepatic tumors, those tools are often useful as a back-up for the routine tests but not for initial procedures. It should also be kept in mind that hepatic arteriography performed in the high risk group often leads to detection of small cancers. In cirrhotic patients with small hepatocellular carcinoma, surgical resection should be done, providing the clinical status and hepatocellular reserve are adequate.

    Notes: Abstract We designed a transparent box to reconstruct cross sectional computed tomography (CT) imagings of the liver into a three dimensional form. The objective was to clearly visualize the area of lesion and to facilitate clinical teaching. This box (31.5×22.0×18.5 cm) is made of acrylic board containing 16 demountable panels layered horizontally at 10-mm intervals. The transparency of the CT film is projected onto these panels at each height of the liver, and findings including location of the tumor, main vessels and adjacent organs are outlined with an erasable marker. After completion of each tracing, the panels are replaced in the box and the total layer forms a completed picture of the CT findings. Since 1981, we have used this tool to assess resectability and/or to select adequate procedures for treating 54 patients with liver tumor. The solid picture gives an definite location of the tumor and its extension. In the clinical work-up, indication for surgery and a procedure of choice can be discussed by the team, using this visual aid.

    Notes: Abstract To determine the characteristic radiologic findings of inflammatory pseudotumor of the liver, various imagings of ten patients (11 lesions) with proven diagnoses of inflammatory pseudotumor were reviewed. Radiologic examinations, i.e., computed tomography (CT; 11 lesions), ultrasonography (11 lesions), magnetic resonance imaging (MRI; 6 lesions), angiography (10 lesions), CT during arterio-portography (CTAP; 3 lesions), and gallium-67 scans (9 lesions) were analyzed for their utility in diagnosis. No inflammatory pseudotumor showed a fibrous capsule around the lesion. Ten of the 11 lesions were poorly demarcated on most of the imagings, and all 11 lesions showed delayed and/or prolonged enhancement on CT or MRI. Arterio-portal shunting was observed in 4 lesions after contrast material administration on CT or angiography. Central lesions with suspiciously high fibrotic tissue content were demonstrated in 5 lesions on CT or MRI. Major vessels coursing in the lesions were demonstrated in 4 lesions by CT, MRI, and CTAP. Inflammatory pseudotumor of the liver should be included in the differential diagnosis in patients with hepatic masses, even if the patients are asymptomatic. If radiologic examinations suggest inflammatory pseudotumor, percutaneous biopsies should be performed so that unnecessary surgery can be avoided.

    Notes: Abstract We investigated the synergistic anti-tumor effects of K-18 (conjugate of human γ-globulin and melphalan) and concomitantly administered hyperthermia on Lewis lung carcinoma in mice. The antitumor effect of a subeffective dose of K-18 or an equivalent dose of melphalan alone was enhanced by local hyperthermia. K-18 administration demonstrated a greater potentiation for inhibition of tumor growth than that of melphalan alone. Local hyperthermia plus K-18 reduced the dose of melphalan required for tumor growth inhibition by melphalan alone. The combined application of K-18 and hyperthermia for treating cancer warrants further study.

    Notes: Abstract Porcine hepatocytes are used in the hybrid artificial liver support system that we are developing because of their high level of liver functions in vitro and because human hepatocytes can not be used in Japan for ethical reasons. Spherical multicellular aggregates or spheroids have been found to be effective in vitro for long-term maintenance of liver functions. Therefore, we formed spherical multicellular aggregates (spheroids) of primary porcine hepatocytes using a polyurethane foam (PUF) as a culture substratum and analyzed their drug metabolic functions in vitro. Primary porcine hepatocytes inoculated into the pores of a flat PUF plate (25 × 25 × 1 mm), spontaneously formed spheroids within the range of 100 to 150 μm in diameter 24 to 36 h after inoculation. The formed spheroids were attached to the bottom surface of the PUF pores, and their morphology and viability were maintained for more than 12 days. The P-450 activity in the spheroids of porcine hepatocytes was demonstrated by detecting production of monoethylglycinexylidide from lidocaine. In addition, the conjugation enzyme activity was demonstrated by detecting glucuronidation and sulfation of acetaminophen. These activities were maintained for 12 days at a level twice as high as in the monolayer culture. This result shows that the porcine hepatocyte spheroids formed by using PUF can maintain the drug metabolic functions important in a hybrid artificial liver device. Consequently, culturing porcine hepatocyte spheroids using PUF seems to be promising for development of a hybrid artificial liver.

    Notes: Abstract Rapid formation of spherical multicellular aggregates (spheroids) of hepatocytes and expression of liver-specific functions are important in developing a hybrid artificial liver. The relation between these points and the surface characteristics of the culture substratum are investigated in this article. Polyurethane foam (PUF) was used as a culture substratum for hepatocytes. Rat, dog, and porcine primary hepatocytes spontaneously formed a spheroid within 1.5 days in the pores of a hydrophilic PUF with a contact angle of 53.4±2.7°. Rat and dog primary hepatocytes formed a spheroid within 3 and 7 days of culture, respectively, in hydrophobic PUF with a contact angle of about 100°. The rates of albumin secretion and ammonia metabolism at 5 days of culture of porcine hepatocytes were 31 μg of albumin/106 nuclei/day and 0.018 μmol of NH3/106 nuclei/h, respectively, about 2 times higher than the values with hydrophobic PUF. It is very important to control the hydrophilicity of the PUF surface to develop an effective artificial liver module.
