[Chronic pancreatitis--surgical therapy by drainage procedures]

The development of drainage techniques in surgery of chronic pancreatitis are reported, those from short to the now used long-distance anastomoses. To remove incarcerated stones of the prepapillary region the author proposes to perform additional transduodenal papilla-sphincterotomy into the duct of wirsung. Good late results of 76 in this manner operated patients up to 8 years later are reported as evaluated together with R. Pichlmayr/H. Bunzendahl, Hannover. This non-resecting procedure seems to have a lower mortality rate than duodenopancreatectomy because of Zero-mortality in the last 45 operated cases.
