Isotopic composition of cattle pancreatic stones: biological and geochemical implications.
1977
Latitudinal variations of the O18/O16-ratios of carbonate and phosphate of cattle pancreatic stones parallel a similar pattern of oxygen isotope values in rain water. C13/C12-ratios were virtually identical for the 7 cases studied. Isotopic measurements of mammalian hard tissues may be used for studying short-term climatic variations through Quaternary.
Inkarzeration eines Pankreassteinfragmentes im distalen Pankreasgang nach Therapie durch extrakorporale Stoßwellenlithotripsie (ESWL)
2001
A partial or total absence of stones in pancreaticolithiasis therapy can be reached by using ESWL. We report on a patient who happened to get an incarceration of a fragment in the distal pancreatic duct after having been treated by ESWL without a previous sphincterotomy to the ductus Wirsungianus. This emphasizes the recommendation to carry out a papillotomy of the pancreatic main duct before applying ESWL to pancreatic stones.
Laser fragmentation of pancreatic duct stones using a rhodamine laser with an automatic stone-tissue detection system. Basic in-vitro studies
1997
OBJECTIVES The aim of our study was to examine the suitability of a rhodamine 6G laser with an integrated stone-tissue detection system (STDS) for fragmenting pancreatic stones. METHODS A total of 64 pancreatic duct stones were measured for weight, diameter, main chemical components and in some cases for their computerized tomography density. Recognition of all stones was checked with the standard STDS or a prototype version. Number of fragmentation pulses, total fragmentation energies and correlation with the individual stone parameters were determined. The quality of the tissue-detection mode was evaluated in postmortem pancreata. RESULTS The standard STDS detected only 45% of the pancrea…
