    Description / Table of Contents: Zusammenfassung Bei sechs Patienten mit adrenalem Phäochromocytom erfolgte die Lokalisationsdiagnostik durch Ultraschalluntersuchung, Phlebographie der Nebennieren und selektiver Katecholaminbestimmung im Blut der Vena cava sowie der Nebennierenvenen. Durch die selektive Katecholaminbestimmung konnten alle Phäochromocytome lokalisiert werden, durch die Ultraschalluntersuchung fünf, durch die Phlebographie vier. Ein Phäochromocytom von 1,5 g Gewicht, das nur durch die selektive Katecholaminbe-stimmung, nicht aber durch Ultraschall oder Phlebographie lokalisiert wurde, konnte computertomographisch dargestellt werden. Um Fehldiagnosen bei der selektiven Katecholaminbestimmung zu vermeiden, darf vor der Blutentnahme aus den Nebennierenvenen kein Röntgenkontrastmittel injiziert werden, da dies zu einer erheblichen Adrenalin- oder Noradrenalinfreisetzung aus dem Nebennierenmark führen kann.
    Notes: Summary In six patients with adrenal pheochromocytoma the tumors were localized by ultrasonography, phlebography of the adrenal glands and by estimation of plasma catecholamines selectively obtained from the vena cava and the adrenal gland veins. All tumors were localized by selective catecholamine estimation, five by ultrasonography, and four by phlebography. The smallest pheochromocytoma of 1.5 g weight was only localized by selective catecholamine estimation but not by ultrasonography or phlebography. This tumor, however, had been visualized by computed tomography. To avoid diagnostic errors by selective catecholamine estimation, it is important to withdraw blood from the adrenal gland veins prior to the injection of any radiographic contrast media, since this may result in an extremely enhanced secretion of catecholamines from the adrenal medulla.

    Description / Table of Contents: Résumé L'échographie opératoire a été pratiquée chez 21 malades porteurs au total de 22 tumeurs endocrines du pancréas: 17 accusaient un hyperinsulinisme organique, 4 un Zollinger-Ellison, 1 un insulinome associé à un PPome. Quinze des insulinomes se manifestaient par une lésion visible et palpable. Chez 2 malades la lésion ne fut pas découverte lors de l'intervention initiale et c'est seulement à la seconde opération que la tumeur fut détectée grâce à l'échographie chez l'un des deux, l'autre devent être opéré ultérieurement. Le PPome ignoré fut identifié par l'exploration. Chez 4 malades présentant un syndrome de Zollinger-Ellison, un gastrinome fut localisé dans le pancréas et 2 dans la paroi duodénale par la palpation. Chez un patient le gastrinome ne fut découvert ni par l'exploration chirurgicale ni par la sonographie. Dans l'un des cas identifiés, la tumeur fut décelée par l'échographie. Chez un malade la tumeur était trop petite pour être accessible à l'exploration échographique. Deux des cas présentaient des métastases hépatiques qui ne pouvaient être découvertes que par l'échographie hépatique. Il résulte de cette expérience que l'échographie opératoire doit être une exploration systématique lors des interventions pour apudomes.
    Abstract: Resumen Se practicó ultrasonografía operatoria (USIO) en 21 pacientes con 22 tumores endocrinos del páncreas. Diecisiete pacientes exhibían hiperinsulinismo orgánico; 4 presentaban sindrome de Zollinger-Ellison. Un paciente con insulinoma tenía un PPoma como segundo tumor. Quince de los insulinomas investigados por USIO eran visibles y palpables. En 2 pacientes no se halló tumor durante la operación inicial. En la reoperación se detectó un tumor por USIO solamente; está planeada la reoperación en el otro paciente. El PPoma fue un hallazgo incidental durante la USIO. En los pacientes con el síndrome de Zollinger-Ellison, un gastrinoma fue localizado en el páncreas y 2 en la pared duodenal mediante palpación. En un paciente no se encontró gastrinoma, ni por exploración quirúrgica ni por USIO. En uno de los casos positivos el tumor fue demostrable por USIO; en el otro paciente era demasiado pequeno para ser delineado. Dos de los casos tenían metastasis hepáticas que pudieron ser demostradas por USIO solamente. De nuestra experiencia podemos concluír que la USIO debe ser realizada rutinariamente en el curso de operaciones para APUDomas pancreáticos.
    Notes: Abstract Intraoperative ultrasound (IOUS) was performed in 21 patients with 22 endocrine tumors of the pancreas. Seventeen patients suffered from an organic hyperinsulinism, 4 had Zollinger-EUison syndrome. One patient with an insulinoma had a pancreatic-polypeptide-producing adenoma (PPoma) as a second tumor. Fifteen of the insulinomas investigated by IOUS were visible and palpable. In 2 patients no tumor was found during initial operation. At reoperation 1 tumor was detected by IOUS only, the reoperation in the other patient is planned. The PPoma was an incidental finding during IOUS. In 4 patients with Zollinger-Ellison Syndrome, 1 gastrinoma was localized in the pancreas and 2 in the duodenal wall by palpation. In 1 patient we found no gastrinoma by either surgical exploration or by IOUS. In 1 of the positive cases the tumor was demonstrable by IOUS. In the other patient it was too small for imaging. Two of these patients had liver metastases, which could be demonstrated by IOUS only. We conclude that IOUS should be performed routinely in operations for pancreatic APUDomas.

    Description / Table of Contents: ZusammenfaBung In den letzten Jahren nehmen die Vagotomieverfahren einen immer gröBeren Raum in der Ulcuschirurgie ein. Eine Umfrage unter deutschen Chirurgen zeigte jedoch, daB die Mehrzahl immer noch der 2/3-Resektion vertraut. Aufgrund der ErgebniBe prospektiver Studien muB die Resektion als Therapie des unkomplizierten Ulcus duodeni abgelehnt werden. Sie ist jedoch weiterhin indiziert bei Ulcuskomplikationen, vor allem bei der Blutung, der Penetration callöser Geschwüre und bei Rezidiven nach Vagotomie, sowie beim Ulcus ventriculi Typ I.
    Notes: Summary In recent years vagotomy has become more and more prefered in ulcer surgery. Based on the results of prospective trials, gastric resection should be abandoned as treatment of uncomplicated duodenal ulcer. Resections are still indicated for most ulcer complications, such as bleeding, penetration of chronic ulcer, and in recurrent ulcers after vagotomy. The same is true for gastric ulcer type I. Questionnaires indicate, however, that German surgeons still favor the two-thirds resection.

    Description / Table of Contents: Zusammenfassung Das Versagen der konservativen Therapie bei den schweren Verlaufsformen der akuten Pankreatitis, denen eine hämorrhagisch-nekrotisie-rende Entzündung zugrundeliegt, ist einer der Gründe für ihre operative Behandlung mit dem Ziel, die Nekrosen zu entfernen. Bei den partiellen Nekrosen ging die Letalität unter operativer Therapie erheblich zurück, bei den subtotalen und totalen Nekrosen sind erst Einzelerfolge zu verzeichnen. Hier gilt die Forderung nach früherer Erkennung und ℛorzeitiger Operation”, d. h. vor Auftreten lebensbedrohlicher Komplikationen.
    Notes: Summary The failure of conservative treatment in severe acute hemorrhagicnecrotizing pancreatitis is one main reason for operative treatment of the diseases by removal of the necrotic masses. In cases of partial necrosis of the pancreas, mortality was significantly reduced by operative treatment; in subtotal and total necrosis only a few patients survived. Early diagnosis and early operation should be done before life-threatening complications occur.
