These proceedings of an international meeting held as recently as December 1996 cover diagnostic procedures in pancreatic disease, together with the progress made over the last 10 years in treating acute and chronic pancreatitis as well as pancreatic cancer. The meeting also covered standards in medical and surgical treatment.

"International Practices in Pancreatic Surgery" describes in great detail general and specific technical aspects of the standard resection procedures of the pancreas. Each surgical step during the pancreatic operation is precisely outlined and accompanied by drawings and photographs. The main chapters on pancreatic carcinoma, chronic and acute pancreatitis are written by the editors. An international faculty complements the texts by describing their own personal techniques. This concept offers the greatest possible overview of the techniques used by experienced surgeons.

Ausgehend von einer interdisziplin{r und international abgestimmten neuartigen Begriffsbestimmung der Antiseptik aus klinischer Sicht werden dieIndikationen f}r die Antiseptik in den verschiedenen Disziplinen erstmalig in monographischer Form mit Empfehlungen zur Wirkstoffauswahl behandelt.Die hygienisch und klinisch begr}ndeten Anwendungsempfehlungen zur prophylaktischen und therapeutischen Antiseptik bestimmen den Nutzen f}r den Leser ebenso wie die Darstellung der wissenschaftlichen Grundlagen f}r die klinische Antiseptik. Der didaktische Ansatz ist dadurch gekennzeichnet, da~ die k}nftigen Arbeitsschwerpunkte f}r die verschiedenen klinischen Disziplinen sowie f}r die Fachgebiete der theoretischen Medizin, insbesondere der Hygiene, der medizinischen Mikrobiologie und der klinischen Pharmakologie sowie f}r mit der Entwicklung und Pr}fung von Pharmaka besch{ftigten Institutionenbzw. der Industrie herausgestellt werden.
