【摘要】：目的:利用磁共振胰胆管造影(M RCP)及常规M R I序列,探讨胆囊管变异与胆囊结石发生的相关性。方法:回顾性分析符合纳入标准的382例患者的MRI及临床资料,比较常见变异胆囊管与正常胆囊管患者胆囊结石患病率差异。胆囊管变异由两位影像医师根据MRI常规及2D-MRCP序列独立盲法诊断,胆囊结石经手术或MRI和B超检查共同证实。结果:正常胆囊管154例,胆囊管变异228例(变异率59.7%),其中胆囊管高位汇合20例,汇合于肝总管前或后壁130例,中间汇合24例,低位汇合16例,平行胆囊管20例,胆囊管低位汇合伴胆囊管平行走行11例,短胆囊管7例。变异胆囊管中,胆囊管低位汇合和胆囊管低位汇合伴胆囊管平行走行患者结石患病率(分别为68.8%、63.4%)较正常胆囊管患者差异有统计学意义(P=0.000、0.003),胆囊管高位汇合、汇合于肝总管前或后壁、中间汇合、平行汇合、短胆囊管患者胆囊结石患病率(分别为20.0%、26.9%、25.0%、40.0%、0)较正常胆囊管患者差异不具有统计学意义(P0.05)。结论:胆囊管变异率较高,变异胆囊管中,胆囊管低位汇合、胆囊管低位汇合伴胆囊管平行走行是促进胆囊结石形成的危险因素。
[Abstract]:Objective: to study the correlation between cholecystolithiasis and cystic duct variation by Mr cholangiopancreatography (MRCP) and routine MRI sequence.Methods: the MRI and clinical data of 382 patients in accordance with the inclusion criteria were analyzed retrospectively and the difference in the prevalence of gallstone in the patients with common variant cystic duct and normal cystic duct was compared.Cholecystolithiasis was diagnosed by two imaging physicians according to MRI routine and 2D-MRCP sequence. Cholecystolithiasis was confirmed by operation or MRI and B ultrasound.Results: 154 cases of normal gallbladder duct, 228 cases of cystic duct variation (59.7%), 20 cases of high confluence of gallbladder duct, 130 cases of confluence in front or posterior wall of common hepatic duct, 24 cases of intermediate confluence, 16 cases of low confluence, 20 cases of parallel cholecystic duct.There were 11 cases of low confluence of gallbladder duct with horizontal walking of gallbladder duct and 7 cases of short gallbladder duct.In the variant gallbladder duct, the incidence of calculi in patients with low confluence of gallbladder duct and low confluence of cholecyst duct with horizontal walking of gallbladder duct (68.8% 63.4%, respectively) was significantly higher than that of normal patients with cholecystic duct (P < 0.0000. 003), and the rate of cholecystic duct confluence was higher than that of normal cholecystic duct.The incidence of gallstone in the patients with short gallbladder duct (20.0 / 26.9 / 25.0) was not significantly higher than that in the patients with normal cystic duct (P < 0.05). The incidence of gallstone in patients with short gallbladder duct (20.0 / 26.9 / 25.0) was not significantly higher than that in patients with normal cholecystic duct (P < 0.05).Conclusion: the mutation rate of the cystic duct is high. In the variant cystic duct, the low confluence of the cystic duct and the low confluence of the cholecyst duct with the walking of the gallbladder duct are the risk factors to promote the formation of cholecystolithiasis.
