    Abstract The Einstein-Maxwell equations are integrated for a tilted Bianchi type VIo space-time with ‘stiff’ matter and an electromagnetic field. The solution represents an anisotropic homogeneous cosmological model which tends to isotropic expansion.

    Notes:
    Abstract We present new exact solutions of the Einstein-Maxwell equations for cosmological models of Bianchi type VIo. The solutions represent anisotropic universes with source-free electro-magnetic fields and perfect fluid matter. The behaviour near to and far from initial singularities is examined.

    Description / Table of Contents:
    Zusammenfassung. Hintergrund: Aktuelle Aspekte der Magencarcinomchirurgie betreffen das Resektionsausmaß am Magen, die Indikation zur multivisceralen Resektion, den Umfang der Lymphknotendissektion und ein optimales präoperatives Tumorstaging. Patienten und Methodik: In einer retrospektiven Analyse wurden epidemiologische, operative, postoperative und histopathologische Daten bei 284 Magencarcinompatienten erfaßt. Ergebnisse: Unsere Ergebnisse favorisieren die subtotale Gastrektomie bei allen T-Stadien im distalen und mittleren Magendrittel unter der Voraussetzung eines oralen Sicherheitsabstands von 5 cm beim intestinalen und von 10 cm beim diffusen Lauren-Typ. Zusätzliche Organresektionen sind nur bei direkter Tumorinvasion und nicht im Rahmen einer D2-Lymphknotendissektion indiziert. Der Umfang der D2-Lymphknotendissektion sollte sich an der Lokalisation des Primärtumors orientieren. Multimodale Therapiekonzepte und die hohe Letalität der explorativen Laparotomie begründen den Einsatz der diagnostischen Laparoskopie bei T3/4-Tumoren und bei Verdacht auf Fernmetastasierung in der bildgebenden Diagnostik. Schlußfolgerung: Trotz standardisierter Magencarcinomchirurgie scheint ein an Lokalisation und Ausdehnung des Tumors orientiertes chirurgisches Konzept gerechtfertigt.
    Notes:
    Summary. Background: Current problems in gastric cancer surgery concern the extent of gastric resection, the need for abdominal evisceration, the degree of lymphadenectomy, and optimal preoperative tumor staging procedure. Patients and methods: In a restrospective analysis, data on epidemiology, extent of surgery, histopathology, postoperative complications, mortality, and survival in 284 gastric cancer patients were evaluated. Results: Our results are in favor of subtotal gastrectomy performed for all T stages located in the distal or middle third, provided that a tumor-free margin of 5 cm in intestinal type and 10 cm in diffuse Lauren's type tumor can be achieved. Additional organ resections are indicated only if direct tumor invasion has occurred, and should not be part of an extended lymphadenectomy procedure. The degree of lymph node removal should be guided by the primary tumor site. Multimodal therapeutic approaches and high postoperative mortality after exploratory laparotomy justify the use of diagnostic laparoscopy in T3/4 tumors and if diagnostic scans suggest possible tumor spread. Conclusion: Even though surgery for gastric cancer is well standardized, a tailored surgical approach to different extent of gastric cancer appears warranted.

    Description / Table of Contents:
    Zusammenfassung. Wir kombinierten ein neu entwickeltes fiberoptisches ambulantes Meßsystem zur Bestimmung von intragastralem Bilirubin (Bilitec 2000®, Synectics Medical Inc., Schweden) mit der gastroduodenalen Langzeitmanometrie bei 10 gesunden Probanden und 10 beschwerdefreien Patienten nach Billroth-I-Resektion (BI-Resektion). Im Vergleich zur Kontrollgruppe war die circadiane Bilirubinexposition und die Anzahl exzessiver Schwankungen der intragastralen Bilirubinkonzentration (mehr als 20 % und länger als 5 min) bei den BI-resezierten Patienten signifikant erhöht (p 〈 0,05). Der interdigestive Motilitätszyklus (IMC) war bei den Patienten durch das gehäufte Auftreten verschiedener Typen abnormal propagierter Phase-III-Aktivitätsfronten gekennzeichnet. 90,1 % aller Bilirubinanstiege gingen in der Patientengruppe zeitlich mit abnormalen propagierten Phase-III-Aktivitätsfronten einher. In Fällen eines erhöhten duodenogastralen Refluxes erscheint die ambulante intragastrale Bilirubinbestimmung in Kombination mit der gastroduodenalen Langzeitmanometrie als praktikable Methode zum circadianen Monitoring von Motilität und Reflux.
    Notes:
    Summary. We combined a newly developed ambulatory fiberoptic system for detecting intragastric bilirubin (Bilitec 2000, Synectics Medical Inc., Sweden) with prolonged measurement of gastroduodenal motility in 10 healthy volunteers and 10 patients following BI resection. Circadian intragastric bilirubin exposure and the total number of tremendous changes of bilirubin absorption (more than 20 %, over a period of at least 5 min) were significantly increased in the BI-resected patients (P 〈 0.05). In patients the interdigestive motility cycle (IMC) was characterized by the appearance of several types of abnormally propagated phase III activity fronts. Of the tremendous increases of bilirubin absorption in the patient group, 90.1 % were associated with abnormally propagated phase III activity fronts. In cases of increased duodenogastric reflux, the combination of ambulatory intragastric bilirubin measurement and long-term manometry seems to be feasible to assess motility and reflux simultaneously.
