摘要
目的：探讨分析胰头导管腺癌病灶大小及分化程度与64-MDCT曲面重建下测得主胰管及胆总管直径的相关性。方法：回顾性分析2013年9月23日—2015年6月17日经病理学证实的胰头导管腺癌45例患者的MDCT影像学资料，对胰头导管腺癌病灶最长径与主胰管直径及胆总管直径进行统计学分析。结果：高分化导管腺癌7例，中分化导管腺癌21例，低分化导管腺癌17例；胰头癌的平均大小（2.33±0.86） cm，与胆总管十二指肠后段、上段直径皆无相关性，与梗阻上游胆总管平均直径存在正相关性。胰头癌的大小与胰腺颈、体及尾部主胰管直径皆无相关性，但与主胰管平均直径存在负相关，且与梗阻上游胰管平均直径存在正相关性。低分化与中分化导管腺癌上游主胰管平均直径间差异有统计学意义，高分化、中分化及低分化导管腺癌间上游胆管直径间差异无统计学意义。结论：主胰管直径一定程度上和胰头癌的分化程度有关。
Abstract
Objective: To investigate the relationship between the size of the lesion, differentiation grade and the diameter of the pancreatic duct and common bile duct by using imaging surface reconstruction in 64-MDCT. Methods: Forty-five patients MDCT imaging with pancreatic ductal adenocarcinoma(confirmed by pathology) were retrospective analyzed from September 23, 2013 to June 17, 2015. The diameter of the main pancreatic duct, the longest diameter of the main pancreatic duct and the diameter of the common bile duct were statistically analyzed. Results: High(7 cases), medium(21) and low(17) differentiated ductal adenocarcinoma were confirmed in this group; and average size of pancreatic head carcinoma was (2.33±0.86) cm. There was no correlation between differentiated grade and its average diameter of common bile duct at upper and posterior duodenal level. There was positive correlation between differentiated grade and average diameter of common bile duct obstruction upstream. There was no correlation among the size of pancreatic head carcinoma with diameter of the neck, body and tail of the main pancreatic duct, and negative correlation between the pancreatic head carcinoma and average diameter of the main pancreatic duct and positive correlation with average diameter of the pancreatic duct obstruction at upstream level. Between poorly and moderately differentiated pancreatic ductal adenocarcinoma, average diameter of the upper main pancreatic duct was statistically significant difference. Upstream bile duct diameter was no statistically significant difference among poorly, moderately and highly differentiation of ductal adenocarcinoma. Conclusion: Differentiation garde of pancreatic head carcinoma was certainly correlated with the average diameter of the main pancreatic duct.
