    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 This report describes our data regarding repeated injection sclerotherapy using a newly designed over-tube. We treated 17 consecutive patients with esophageal varices, (3 acute, 6 elective and 8 prophylactic). An intravariceal injection of 5 per cent ethanolamine oleate was administered, using a newly designed transparent over-tube containing a second lumen for a flexible injection needle. This over-tube provides an easier, safer, shorter-in-time method of sclerosing esophageal varices. One of the 17 patients died as a result of liver failure associated with advanced cirrhosis and a concomitant hepatoma. Eradication of esophageal varices was attained in the remaining 16 patients, after an average of 5.0 injections over an average period of 5.8 weeks (range: 3–7 injections during 3–11 weeks). No complications, such as esophageal perforation or aspiration pneumonia were encountered. Recurrent variceal bleeding has not occurred during the 9 months follow-up.

    Notes: Abstract Accessory spleens of 1.5 cm in size were preoperatively identified by the combined use of computerized tomography and splenic scintigraphy in two patients with hematologic diseases. After the accessory spleen had been removed from the first patient, who had persistent hereditary spherocytosis and had undergone a splenectomy 15 months before, a postoperative decrease in hyperbilirubinemia was noted. In the other patient who had idiopathic thrombocytopenic purpura, a successful accessory splenectomy was done at the same time as her splenectomy, and was followed by 6 months' complete remission. These events indicate that preoperative investigations using computerized tomography and scintigraphy are indispensable for ruling out an accessory spleen in those patients for whom splenectomy needs to be done in order to alleviate hematologic disorders.

    Description / Table of Contents: Résumé Une série de 231 malades porteurs de varices oesophagiennes secondaires à une hypertension portale par bloc intrahépatique qui furent traités par une anastomose entre la veine gastrique gauche et la veine cave est présentée par l'auteur. Furent à déplorer cinq morts postopératoires (2.2%). Quatre-vingts décès (34,68%) survinrent secondairement. Les 146 survivants ont été suivis pendant une période moyenne de 66 mois. L'hémorragie récidiva chez 17 d'entre eux (7,4%). Le taux de survie à 5 ans s'est élevé à 69,8% au total et à 62% chez le cirrhotique. Le syndrôme d'Eck ne fut jamais observé et le flux portai fut conservé chez 43 opérés qui ont été étudiés par angiographie et sonographie. L'anastomose entre la veine gastrique gauche et la veine cave est une opération sûre et efficace qui perturbe peu l'hémodynamique portale pendant un long espace de temps après l'intervention.
    Abstract: Resumen En 1967 diseñamos una derivación selectiva, el “shunt” vena gástrica izquierda-cava (SVGIC) con el propósito de lograr una descompresión selectiva de las várices esofágicas por vía de la vena gástrica izquierda. Se presentan los datos de 231 pacientes con várices esofágicas e hipertensión portal secundaria a bloqueo intrahepático sometidos a este procedimiento. Se presentaron 5 muertes operatorias (2.2%) y 80 muertes tardías (34.6%), lo cual resultó en 146 sobrevivientes en un seguimiento promedio de 66 meses. Hemorragia varicosa postoperatoria ocurrió en 17 (7.4%). La tasa de supervivencia a cinco años fué de 69.8% para la totalidad del grupo, y de 62.0% para los cirróticos. El sindrome de Eck no fue observado, y el flujo portai prógrado apareció conservado en todos los 43 pacientes que fueron examinados por angiografía o por ultrasonido. El SVGIC es una forma efectiva y segura de tratamiento quirúrgico. El procedimiento logra la descompresión des las varices esofágicas y previene la hemorragia recurrente postoperatoria; funciona en forma altamente selectiva por un largo período de tiempo y resulta en una menor interferencia con la perfusión portal del hígado.
    Notes: Abstract Data on 231 patients with esophageal varices and portal hypertension secondary to intrahepatic block who underwent a left gastric venous caval shunt are presented herein. Operative death occurred in 5 (2.2%) and late death in 80 (34.6%), resulting in 146 survivors at a mean follow-up period of 66 months. Postoperative variceal bleeding occurred in 17 (7.4%). Five-year survival rate was 69.8% overall, and 62.0% in patients with cirrhosis. Eck's syndrome occurred in none, and a prograde portal flow was preserved in all 43 patients who were examined angiographically or ultrasonically. Left gastric venous caval shunt is a safe and effective surgical treatment which provides less insult to portal hemodynamics for a long postoperative period of time.

    Notes: Abstract In attempts to produce esophageal varices in dogs, we designed a procedure based on the concept of hyperdynamic flow. The first stage operation involved the achievement of an arteriovenous shunt between the left renal artery and the proximal splenic vein, in concert with the distal splenic venous-left renal venous shunt. About one month after the initial operation, sixteen of the twenty-eight dogs had tolerated the manipulations. Both shunts proved to be functioning well in six of sixteen survivors, in which an ameroid constrictor was placed around the splenic vein just proximal to the confluence of the left gastric vein. Again one month later, in five of these six, esophageal varices were evidenced, both endoscopically and histologically. Arterialization of left gastric vein concomitant with the distal splenorenal shunt, gave rise to a hyperdynamic state in the upper stomach and resulting in reproducible esophageal varices.

    Notes: Abstract We designed a reproducible canine model of esophageal varices, based on the concept of a regional hyperdynamic state in the upper stomach. Arterialization of the left gastric vein concomitant with the distal splenorenal shunt led to a stable hyperdynamic state and reproducible esophageal varices occurred. In the long-term follow-up of these dogs with varices, the erosive gastritis seen in the upper stomach learly resembled clinically observed lesions. Hemodynamic and morphological studies revealed that gastric mucosa of these animals was in an ischemic state, even though there was a remarkable increase in blood flow in the submucosal area. It is suggested that the decrease in mucosal blood flow, as induced by the hyperdynamic state caused erosive gastritis.

    Notes: Abstract The time of appearance of the left gastric vein on serial celiac arteriograms in patients with portal hypertension and esophageal varices was compared with that of the portal vein to assess regional hemodynamics in the left venous portion of the stomach, an area located in close proximity to the varices. In two thirds of all the patients with cirrhosis or non-cirrhotic idiopathic portal hypertension (IPH), the left gastric vein was visualized earlier or simultaneously than or with the portal vein, while in all but one patient with prehepatic portal obstruction, there was a delayed opacification of the left gastric vein. These results suggest the presence of a hyperdynamic circulatory state which promotes venous hypertension in the left gastric venous area of the stomach of a considerable number of patients with cirrhosis or IPH. In such a hemodynamic state, selective decompression of varices can be achieved by a left gastric venous caval shunt.

    Notes: Abstract Thirty patients with esophageal varices, portal venous obstruction and a histologically proven normal liver underwent either one of 2 different types of surgery. Shunt surgery was performed on 20 patients: 9 had a mesocaval shunt, 3, a splenorenal shunt, 4, a left gastric venacaval shunt, and 4, a distal splenorenal shunt. Conversely, direct interruption was performed on the other 10 patients: 6 underwent an esophageal transection, and 4 underwent a resection of the proximal stomach. Re-hemorrhage occurred in 7 of the former 20 patients but not in any of the 10 on whom the direct interruption method was used. In 6 of these 7 patients who experienced rebleeding, subsequent direct interruption surgery led to control of the bleeding. One patient died of a variceal hemorrhage one month postoperatively. The total 10 year cumulative survival rate was 86.3 per cent. In the light of these findings, we believe that methods of direct interruption, such as esophageal transection, may well be the approach of choice for patients with esophageal varices caused by extrahepatic portal venous obstruction.

    Notes: Abstract The validity of an ultrasonic duplex system for assessment of portal blood flow was clinically investigated. The maximum portal blood flow velocity was measured using this system (X) in ten patients with liver disease, and data obtained were compared on patients simultaneously undergoing cineangiographic mapping of Lipiodol droplets released into the portal vein through an indwelling catheter (Y). A linear correlation between X and Y was statistically significant (r=0.970, n=13). The ultrasonic duplex system proved reliable for a quantitative assessment of portal hemodynamics.
