    Description / Table of Contents: Zusammenfassung Radiushalsfrakturen sind typische Verletzungen des Kindesalters. Bei geringer Dislokation des Radiusköpfchens ist die konservative Behandlung ausreichend. Bei Abkippwinkeln caber 30° wird die operative Aufrichtung empfohlen and Unterfütterung mit einem Spongiosakeil zur Fixation. Anschließend für 6 Wochen Oberarmgipsverband. In allen Fällen kam es zur vollen Funktionsrückkehr des Ellenbogengelenkes.
    Notes: Summary Fractures of the neck of the radius are typical childhood injuries. Minimal displacement requires only conservative treatment. In cases with more severe dislocation of the head of the radius (more than 30°) operative reduction followed by fixation with a wedge of spongiosa is recommended. Full function of the elbow joint is recovered.

    Description / Table of Contents: Zusammenfassung Bei insgesamt 23 Patienten wurde eine perkutane transhepatische Cholangiodrainage (PTCD) durchgeführt. In 19 Fällen präoperativ bei malignem Verschlußikterus mit Bilirubinwerten über 150 mg/1. Nach 12tägigem Gallefluß von 50 bis 2200 ml/d waren die Bilirubinspiegel deutlich abgesunken und der Allgemeinzustand der Patienten war wesentlich gebessert. Durch die PTCD präoperativ konnte die Letalität palliativ operierter Patienten mit Pankreascarcinom von 23% auf null im Jahre 1978 (n = 13) gesenkt werden. Leicht zu beherrschende Komplikationen traten 5mal auf.
    Notes: Summary Percutaneous transhepatic intubation and drainage of the biliary system was performed in 23 patients. In 19 cases preoperatively because of malignant obstructive jaundice. Within 12 days the bilirubin serum level fell to normal values and patients' general condition showed marked improvement. By preoperative PTCD the mortality of palliative procedures in pancreatic carcinoma decreased from 23% to zero. Complications occurred in five cases and were easy to manage.

    Description / Table of Contents: Résumé De 1964 à 1982, 782 malades ont été traités pour cancer du pancréas. Chez 174 d'entre eux il fut possible de pratiquer une duodénopancréatectomie (22%). Jusqu'à 1977 l'exérèse consista en une opération de Whipple. Elle fut remplacée de 1978 à 1982 par la duodénopancréatectomie totale. La comparaison des résultats obtenus par les deux méthodes permet d'affirmer que la seconde ne présente pas d'avantages substantiels par rapport à la première. La mortalité opératoire n'a pas diminué, la survie n'a pas augmentée alors que l'élévation du taux des résections (supérieur à 26%) pour des tumeurs plus avancées s'est accompagnée d'un risque chirurgical plus important. En ce qui concerne les malades atteints de cancers avancés il a été constaté qu'au cours des cinq dernières années le taux d'inopérabilité s'est élevé de 8 à 23% pendant que le taux de la laparotomie exploratrice s'est réduit de 28 à 5%. Depuis l'introduction du drainage biliaire transpariétal préopératoire le taux de mortalité des méthodes palliatives est tombé à 12%. L'anastomose biliodigestive de choix est l'hépaticojéjunostomie.
    Abstract: Resumen En la República Federal de Alemania la frecuencia de carcinoma del páncreas ha venido en ascenso; en los últimos 20 años ha llegado a más del doble, con alrededor de 7,000 nuevos casos adicionales por año. Un total de 782 pacientes con carcinoma de páncreas fueron tratados por nosotros entre 1964 y 1982; en 174 casos fué posible hacer la resección pancreaticoduodenal (22%). Hasta 1977 preferimos el procedimiento de Whipple, en tanto que la pancreatectomía total fué el procedimiento de escogencia entre 1978 y 1982. Al comparar los resultados de ambos métodos no hallamos ventaja alguna por parte de la pancreatectomía total. La mortalidad operatoria no disminuyó, el período de supervivencia no se prolongó y las mayores tasas de resectabilidad (hasta 26%) para estados tumorales más avanzados se acompañaron de un mayor riesgo quirúrgico. Respecto a los pacientes con cáncer inoperable del páncreas, hemos observado que en los últimos cinco años la tasa de pacientes que no son sometidos a cirugía ha ascendido de 8% a 25%, mientras la tasa de laparotomías exploratorias pudo ser reducida de 28% a 5%. Con el advenimiento del drenaje biliar percutáneo transhepático preoperatorio se ha reducido la mortalidad de nuestros procedimientos quirúrgicos paliativos de 23% a 12%. La anastomosis biliodigestiva de escogencia es le hepaticoyeyunostomía termino-lateral por la técnica de Roux-en-Y. Se realiza gastroenterostomía sólo si hay indicación clínica de alteraciones en el vaciamiento del estómago.
    Notes: Abstract From 1964 to 1982, there were 782 patients treated for carcinoma of the pancreas. In 174 patients pancreaticoduodenal resection was possible (22%). Until 1977 we performed Whipple procedures, while from 1978 to 1982 total pancreatectomy was preferred. Comparing the results of both methods, we did not find any advantages of total pancreatectomy. Operative mortality did not decrease, survival time did not extend, and the higher resection rates (up to 26%) for more advanced tumor stages were accompanied by greater morbidity. With respect to the patients with inoperable cancer of the pancreas, we found over the last 5 years that the rate of those not undergoing surgery has climbed from 8% to 25%, while the rate of exploratory laparotomies was reduced from 28% to 5%. With the advent of preoperative percutaneous transhepatic cholangio-drainage (PTCD), the mortality rate of our palliative procedures dropped to 12%. Biliodigestive anastomosis of choice is the hepaticojejunostomy.

    Description / Table of Contents: Zusammenfassung Wir haben die Beeinflussung der Stromstärke und der 1-Sekundenkapazität beim Atemstoß 1. durch verschiedene Inspirationsvolumina und 2. wechselnde Forcierung untersucht. Wir fanden: 1. daß das FEV1.0 bei ausreichender Forcierung dem vorherigen Inspirationsvolumen direkt proportional ist. Der Quotient aus FEV1.0 und Inspirationsvolumen ist damit über den größten Teil der Vitalkapazität konstant und mit der relativen Sekundenkapazität identisch. 2. Dieser Quotient erweist sich als weitgehend unabhängig von der exspiratorischen Anstrengung, sofern ein relativ geringer alveolärer Schwellendruck überschritten bleibt. 3. Es ist möglich, diese beiden Ergebnisse durch eine mathematische Formulierung zu erklären, die aus dem Strömungsablauf der forcierten Exspiration abgeleitet werden kann.
    Notes: Abstract We examined the influence of different inspiratory volumes and various expiratory efforts on expiratory flow and 1-second capacity. 1. FEV1.0 is proportional to existing inspiratory volume with sufficiently forced expiration. The quotient of FEV1.0 and inspired volume is the same as the 1-second capacity (as % of VC) for most of the vital capacity. 2. The quotient is independent of expiratory effort as long as there is a relatively small excess of alveolar gradient pressure. 3. It is possible to explain these two results by a mathematical formula deduced from the flow of forced expiration.

    Notes: Summary In 21 patients who had undergone total pancreatectomy for pancreatic head carcinoma, the uninvolved pancreas was examined with regard to the type, incidence and regional distribution of duct epithelial proliferation. The results were compared with those in 37 operative specimens from patients with chronic pancreatitis, in 46 normal pancreases from autopsies and with findings in experimental pancreatic carcinogenesis. While the incidence of squamous metaplasia and non-papillary epithelial hypertrophy varied little in the different groups, papillary epithelial hyperplasia was found three times more often in cases of carcinoma, with associated mild duct obstruction. Atypical epithelial proliferation was only detected in the vicinity of carcinomas. Unequivocal transition from papillary hyperplasia to atypical proliferation was not observed. In hamsters treated with dihydroxy-di-n-propylnitrosamine (DHPN) for induction of pancreatic duct carcinomas, the early duct lesions closely resembled atypical epithelial proliferation of human pancreas. It is concluded that (1) papillary epithelial hyperplasia is probably only indicative of early duct obstruction and/or a general neoplastic stimulus, (2) intraductal epithelial proliferation with atypia is a true precursor of duct carcinoma, and (3) chronic pancreatitis lacks atypical duct lesions.

    Notes: Summary The clinico-pathological features of five cases with a distinctive pancreatic tumour are presented. The tumours, which occurred only in young women and an adolescent girl, were of large size (2.5–10 cm), had an uncharacteristic symptomatology and showed fibrous encapsulation with no evidence of metastases. The histological features include (1) solid areas with a monomorphic cell pattern and intracellular PAS positive globules, and (2) large foci of degeneration with cystic necroses, haemorrhages and cholesterol granulomas. Some tumour cells were positive for α1-antitrypsin. The ultrastructural demonstration of zymogen-like granules suggests an acinar origin for the tumours. We therefore propose the term solid and cystic acinar cell tumour. This tumour resembles the so called pancreatoblastomas in small children in some respects. It must be clearly distinguished, on the other hand, from acinar cell carcinoma with its acinic structures and poor prognosis. This lesion is not included in the WHO classification of pancreatic neoplasms.

    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.

    Notes: Abstract A total of 42 islet-cell tumors were examined between 1972 and 1984. Problems of localization were only encountered in 31 tumors less than 2 cm in diameter. Of 31 small tumors, 27 were correctly localized using a combined diagnostic approach: ultrasound was successful in 12/20 tumors, CT in 9/21, angiography in 20/31, intraarterial digital subtraction angiography in 1/2, and pancreatic venous sampling in 13/16. The smallest tumor found by ultrasound and CT was 7 mm in diameter. Intraoperative ultrasound demonstrated all 9 insulinomas examined. Currently, the most useful techniques for localizing small islet-cell tumors are ultrasound, CT, and angiography. CT is particularly useful for tumor staging. Improvement of non-invasive diagnostic techniques will obviate the need for transhepatic blood sampling.

    Notes: Summary Laparoscopic cholecystectomy and appendectomy are widely accepted in clinical practice. In the initial stage, when the method is introduced, there are a number of mistakes, risks, and complications possible. The surgeons, the staff, the instruments, the anesthetist, and, last but not least, the patient, are among the possible contributing causes. We try to analyze the reasons and conditions leading to possible complications. Complications we have experinced are reported. In our conclusions we try to show how it is possible to avoid severe problems.

    Description / Table of Contents: Zusammenfassung Nach Erfahrungen bei 190 Patienten mit stumpfem Bauchtrauma und peritonealer Lavage wurde retrospektiv überprüft, welche Verbesserungen these diagnostische Methode bringt. Verglichen wurden die Ergebnisse bei 82 Patienten mit stumpfem Bauchtrauma ohne Lavage mit den Ergebnissen bei 137 Patienten, bei denen eine diagnostische Bauchspülung erfolgte. Das Intervall bis zur Laparotomie wurde nach Einführung der Lavage wesentlich kürzer. Die Mortalität infolge der Bauchverletzung sank von 8,5 % auf 2,9 %. Die Zahl der „unnotigen” Laparotomien ging von 10 % auf 1,3 % zurück.
    Notes: Summary To study the value of diagnostic peritoneal lavage for the prognosis of patients with blunt abdominal trauma, we compared the results in 82 patients without lavage in the diagnostic procedure with the results in 137 patients with blunt abdominal trauma and peritoneal lavage. Peritoneal lavage led to a remarkable decrease of the interval until laparotomy. The mortality because of abdominal trauma fell from 8.5 % to 2.9 % and the rate of "not requiring" laparotomy from 10 % to 1.3 %. Peritoneal lavage is an aid in improving the prognosis of blunt abdominal trauma.
