MSCT对胆囊结石并十二指肠瘘的诊断价值

目的：探讨MSCT对胆囊结石并十二指肠瘘的诊断价值。方法：回顾性分析6例经手术证实的胆囊结石并十二指肠瘘的CT表现。结果：6例患者中,胆囊萎缩4例,胆囊体积增大2例;胆囊内结石4例,胆囊无结石2例;胆囊壁钙化2例,胆囊内积气2例,胆管积气1例;6例胆囊周围结构显示均欠清晰,4例软组织块影包绕胆囊及十二指肠,3例结石性肠梗阻,结石位于回肠末端。结论：MSCT具有较高的密度分辨力及空间分辨力,结合多平面重组及临床资料,可对胆囊结石并十二指肠瘘的诊断提供重要信息。

Value of multi-slice CT in the diagnosis of cholecystolithiasis complicating with cholecystoduodenal fistula

Objection：To evaluate multi-slice CT（MSCT） in the diagnosis of cholecystolithiasis complicating with cholecystoduodenal fistula.Methods：MSCT findings of 6 patients with surgery proved cholecystolithiasis complicating with cholecystoduodenal fistula were studied retrospectively.Results：Of the 6 patients,there were atrophy of gallbladder（4 patients）,enlargement of the volume of gallbladder（2 patients）,stone in the gallblader（4 patients）,no stome in the gallbladder（2 patients）,gallbladder wall calcification（2 patients）,air within gallbladder（2 patients）,air within bile duct（1 patient）,blurring of pericholecystic structures（6 patients）,encasement of gall bladder and duodenum by soft tissue mass-like shadow（4 patients）,intestinal obstruction due to gallstone with the stone located at terminal ileum（3 patients）.Conclusion：MSCT has high spatial resolution and contrast resolution.When multi-planar reformation（MPR） technique is used and correlated with clinical materials,it plays an important role in the diagnosis of cholecystolithiasis complicating with cholecystoduodenal fistula.
