胰腺炎的超声表现:中日两组病例的比较

目的比较中国和日本两组胰腺炎病例的超声表现.方法分析我院慢性胰腺炎59例、急性胰腺炎84例(A组)和日本杏林大学的慢性胰腺炎128例、急性胰腺炎95例(B组)的超声表现.结果①慢性胰腺炎:A组胰管扩张、胰腺钙化的检出率明显低于B组,分别为23.7% vs 53.0%,13.6% vs 27.3% (均P<0.01).A、B两组胰腺结石合并率分别为18.6%和54.7% (P<0.01), 胆结石合并率分别为52.5%和7.0% (P<0.01).②急性胰腺炎:A、B两组超声表现差别不明显.胰腺结石合并率分别为0.0%和8.4%(P<0.01),胆结石合并率分别为42.9%和7.4% (P<0.01).结论日本组慢性胰腺炎超声主要特点为胰管扩张和胰腺钙化.中日两组急、慢性胰腺炎则分别以胆结石或胰腺结石合并率高为特征.

Sonographic features of pancreatitis: comparison between two groups from Chinese and Japanese

Objective To compare the sonographic characteristics of pancreatitis between two groups of Chinese and Japanese. Methods Sonographic examination was performed in 59 cases of chronic pancreatitis and 84 cases of acute pancreatitis in Sun Yat-sen university (Group A),128 cases of chronic pancreatitis and 95 cases of acute pancreatitis in Japanese Kyorin university (Group B). The sonographic features of the two groups were analyzed. Results For chronic pancreatitis,the detection rates of pancreatic duct dilation and pancreatic calcification in Group A were significantly lower than those in Group B,being 23.7% vs 53.0%,13.6% vs 27.3%,respectively (both P <0.01). The concurrent rates of pancreatic stone and gallstone were significantly different between Group A and Group B,being 18.6% vs 54.7%,52.5% vs 7.0%,respectively (both P <0.01). For acute pancreatitis,there was no significant difference with regard to the sonographic features between two groups ( P >0.05),whereas the concurrent rates of pancreatic stone and gallstone were significantly different between group A and group B,being 0.0% vs 8.4%,42.9% vs 7.4%,respectively (both P <0.01). Conclusion The major sonographic features of chronic pancreatitis from Group B were pancreatic duct dilation and pancreatic calcification. The cases of pancreatitis from China and Japan were characterized as high concurrent rate of gallstone and pancreatic stone,respectively.
