Computerized planimetry of normal and abnormal postmortem pancreatograms.

The aim of this study was to evaluate postmortem pancreatograms by means of computerized planimetry of the ductal drainage area. This method was applied to a total of 136 pancreatograms from autopsy specimens of the human duodenopancreas, with and without pathological changes. The mean value of the total ductal drainage surface area was 5,054 mm2 for normal specimens and 3,938 mm2 in cases with chronic pancreatitis; this difference was statistically highly significant. The analyses also included measuring the accessory duct drainage area (if an accessory duct was present), and the percentage of its share in the total gland area. This share was significantly larger in cases with chronic pancreatitis (24.4%) in comparison to the normal specimens (16.8%). In conclusion, computerized planimetry of pancreatograms supplies valuable data not only on the pathogenesis of chronic inflammation of the gland, but also on some of the possible predisposing factors for this condition.
