This is well reflected in the present study by a ancreatic resections are well known to be procedures carrying a rather high overall mortality, and also failure to rescue in 398 P considerable risk of adverse outcomes including death. Twenty- hospitals of the lowest-volume quintile performing on average 5 major seven years ago, Michael Trede was the first to publish a series from pancreatic resections per year. A minimal caseload of 10 cases per year Mannheim of well above 100 consecutive pancreatoduodenectomies for pancreatic surgery was introduced in Germany in 2004. Since then, without any perioperative mortality. Together with several other it has been ignored by many providers, and not enforced by payers or reports from specialized centers, this led to claims often heard during regulators. The present results suggest that centralization and a the 90s that pancreatic resections should be restricted to centers with markedly higher minimal caseload may save many lives in Germany documented mortality rates below 5%. Obviously, this induced a like it already did in the Netherlands and some other countries. The remarkable publication bias in the way that almost no single-center authors estimate very conservatively that 94 deaths may be avoided series was published in the subsequent years with mortality rates annually in Germany. In a more optimistic scenario of centralization, above that threshold.

Despite the undisputable fact that surgeonvolume, and also hospital volume, are just crude indicators of experience rather than abilities, its major advantage is that it is so easily measurable, and REFERENCES that it is prone to regulatory interventions.
