【摘要】：目的:采用MRCP技術(shù)研究膽總管轉(zhuǎn)角與膽總管擴(kuò)張程度的相關(guān)性。方法:連續(xù)性搜集符合納入標(biāo)準(zhǔn)的321例患者的MRI和臨床資料,其中膽總管無擴(kuò)張218例,輕度擴(kuò)張55例,中度擴(kuò)張20例,重度擴(kuò)張28例,測(cè)量肝外膽管轉(zhuǎn)角大小。采用單因素方差分析和Dunnett-t比較膽總管無擴(kuò)張與不同程度擴(kuò)張患者間轉(zhuǎn)角差異,采用Spearman秩相關(guān)分析膽總管轉(zhuǎn)角與膽總管擴(kuò)張程度的相關(guān)性。結(jié)果:膽總管無擴(kuò)張、輕、中、重度擴(kuò)張患者平均肝外膽管轉(zhuǎn)角分別為(121.40±17.76)°、(118.66±21.65)°、(117.44±23.51)°、(104.68±24.06)°,膽總管重度擴(kuò)張患者轉(zhuǎn)角小于膽總管無擴(kuò)張患者(P0.05),膽總管轉(zhuǎn)角與膽總管擴(kuò)張程度的相關(guān)性系數(shù)為-0.162(P0.05)。結(jié)論:肝外膽管轉(zhuǎn)角與膽總管擴(kuò)張程度呈負(fù)相關(guān),肝外膽管轉(zhuǎn)角隨著膽管擴(kuò)張加重而減小。
[Abstract]:Objective: to study the correlation between the angle of common bile duct and the degree of common bile duct dilation by MRCP technique. Methods: the MRI and clinical data of 321 patients who met the inclusion criteria were collected continuously. Among them, there were 218 cases of choledochus without dilatation, 55 cases of mild dilatation, 20 cases of moderate dilatation and 28 cases of severe dilatation. The angle of extrahepatic bile duct was measured. Univariate analysis of variance (ANOVA) and Dunnett-t were used to compare the angle of conversion between patients without dilatation of common bile duct and different degrees of dilatation. Spearman rank correlation was used to analyze the correlation between the angle of conversion of common bile duct and the degree of dilatation of common bile duct. Results: the mean angle of extrahepatic bile duct was (121.40 鹵17.76) 擄, (118.66 鹵21.65) 擄, (117.44 鹵23.51) 擄, (104.68 鹵24.06) 擄in the patients with severe dilatation of the common bile duct and the mean angle of extrahepatic bile duct was (121.40 鹵17.76) 擄, (117.44 鹵23.51) 擄, (104.68 鹵24.06) 擄in the patients with severe dilatation of the common bile duct. The correlation coefficient between the angle of the common bile duct and the degree of dilatation of the common bile duct was -0.162 (P0.05). Conclusion: the angle of extrahepatic bile duct conversion is negatively correlated with the degree of common bile duct dilatation, and the angle of extrahepatic bile duct conversion decreases with the aggravation of bile duct dilatation.
