Abstract/OtherAbstract:
Aim: to study the possible differences in the final diagnosis of chronic pancreatitis by using standard classification described by Wiersema et al. and the new classification proposed recently by Rosemont.Material and methods: forty-seven patients with the diagnosis of chronic pancreatitis were included in this study. The parenchymal and ductal criteria were studied, the patients were divided in two groups for Wiersema criteria: < 4 criteria, non-diagnostic for chronic pancreatitis and> = 4 criteria, diagnosis of chronic pancreatitis. The same patients were divided in four groups according to Rosemont classification: normal pancreas, indeterminate, suggestive and consistent with chronic pancreatitis. We analyzed these data with Chisquare test reported with 95% confidence intervals (CI).Results: in patients with chronic pancreatitis the most frequent criteria observed were lobularity in 66% of cases and pancreatic duct dilatation and calcifications in 57.4% of cases each. We found a significant statistical association between the results of both classifications (p < 0.05). The highest association is found in patients with more than 4 standard criteria and definitive diagnostic of chronic pancreatitis according to Rosemont classification. In patients who have less than 4 standard criteria the diagnosis is suggestive of chronic pancreatitis by using the Rosemont classification in 27.66% (p < 0.05).Conclusion: these results show that no significant statistical differences are found for patients with > 4 criteria diagnosis by standard criteria. But 27.66% patients with less than 4 standard criteria would be suggestive according to Rosemont classification (p < 0.05). Hence, the new classification would be useful in patients with high suspicion of chronic pancreatitis with < 4 standard criteria but with more significance such as parenchymal lithiasis, lobularity or ductal calcifications.
