    Notes: Abstract Radiation exposure was studied in 327 patients undergoing endoscopic retrograde cholangiopancreatography, or endoscopic papillotomy taking into account fluoroscopy time and incident area exposure. The mean fluoroscopy time was 238±152 seconds and the incident area exposure 3,730±2,790 R×cm2. These results were compared with standard exposures in upper GI series and colon examinations as found in the literature.

    Description / Table of Contents: ZusammenfaBung Als Erweiterung der diagnostischen Cholangiographie hat sich die endoskopische Papillotomie entwickelt, die wir bei 516 (94,7%) von 545 Patienten erfolgreich durchführen konnten. Die Hauptindikationen waren die Choledocholithiasis (405 Fälle) und die organische Papillenstenose (97). 376 (93 %) von 405 Patienten mit Choledocholithiasis wurden nach dem endoskopischen Eingriff steinfrei. Es traten insgesamt 38 Komplikationen auf, die bei 11 (2%) Patienten eine Notfalloperation erforderlich machten, 5 Patienten verstarben (Letalität 1 %). Die schwerwiegendste Komplikation war die Cholangitis. Es zeigt sich, daB die endoskopische Papillotomie den chirurgischen Zweitangriff z. T. ersetzen kann.
    Notes: Summary Endoscopic papillotomy is a further development of endoscopic cholangiography. This therapeutic procedure was succesful in 516 (94.7%) of 545 cases. Choledocholithiasis (405 cases) and papillary stenosis (97) were the main indications for the procedure. Of 405 patients with choledocholithiasis, 376 (93%) are now free of stones. There were 38 (7.4%) complications and 5 (1%) of these had a lethal outcome with (11) (2%) requiring emergency laparotomy. Cholangitis was the most serious complication. It is becoming increasingly evident that the endoscopic papillotomy is replacing reoperation in many cases of choledocholithiasis.

    The ultrastructure of primary hepatocellular cancer in man (1971)

    Notes: Summary The authors carried out an electronmicroscopical study of material obtained by needle biopsy from 12 human hepatocellular carcinomas. Pleomorphism of the cell nuclei and the occurrence in great numbers of cytoplasmic infoldings into the nuclei were striking features. The nucleoli were enlarged and nucleoli of a peculiar target-like form were observed. The endoplasmic reticulum had a vesicularized, fragmented appearance and the membranes were degranulated. The frequent occurrence of fingerprint-like formations of endoplasmic reticulum were also observed. The cristae of the mitochondria were diminished and other degenerative changes were also regularly present. In one case peculiar electron-dense inclusions were seen in the mitochondria. The amount of glycogen granules in the tumour cells seemed to be considerably diminished. No significantly great changes were seen in the Golgi complex. Bile canaliculi as well as desmosomes were regularly found: usually as many as five or six participated in the formation of the canaliculi. Changes were seen also in the microvilli of the biliary and vascular poles. The relation of the tumour cells to the sinusoids proved in many respects to be similar to that in normal liver. It was a frequent finding, however, that the tumour cells formed plates consisting of several cell rows; furthermore, that a basement membrane had developed around the sinusoids, which thus became capillarized, while the sinusoid endothelium became multilayered and the Disse space filled by a fibrin-like substance. The authors compare the alterations observed in human hepatocellular carcinomas with the ultrastructural alterations found in other pathological conditions of the liver and in experimental liver tumours. Based on this comparison they offer conclusions concerning the functional cytopathological significance of the various alterations on the one hand, and the possible pathogenesis of hepatic tumours on the other.

    Description / Table of Contents: Zusammenfassung Zehn Patienten wurden je 2 g Cefotaxim i. v. injiziert. In der Galleflüssigkeit wurden die antibakterielle Aktivität mittels Agardiffusionstest und die Konzentrationen von Cefotaxim und Desacetyl-Cefotaxim mit Hochdruckflüssigkeitschromatographie bestimmt, Die gefundenen Werte erlauben den Einsatz von Cefotaxim bei infektiösen Gallenwegserkrankungen.
    Notes: Summary Ten patients were injected with 2 g cefotaxime i. v. The antibacterial activity in the bile was measured by the agar diffusion test and the concentrations of cefotaxime and desacetyl cefotaxime were determined by high performance liquid chromatography. The values found allow the use of cefotaxime in infectious biliary diseases.
