Oddi括约肌和肝门的体表投影探讨

STUDY ON SURFACE PROJECTION OF ODDL'S SPHINCTER AND HEPATIC HILUS

对41例胆道术后T管造影片分析,发现Oddi括约肌在体表的相对投影点有其规律性,即:70.73%的括约肌投影点在平片上平第2～3腰椎间盘,距正中线右侧4.18cm左右处。我们认为认识此点有助于寻找肝门胆管穿刺点,进而提高经皮肝穿胆道造影术、逆行十二指肠胰胆管造影术等检查的成功率,具有一定的临术意义。

Forty-one cases of T-tube cholangiography after bile duct surgery were analyzed. It is found that there exists a certain regularity regarding the surface projection of Oddi's sphincters, i. e. 70.73% of the projection points are at the level of L2-L3 intervertebral disk, about 4.18cm right to the median line(see the illustration). We believe that this discovery is useful in finding the puncture point for bile duct at hepatic hilus, which, thereby, is of certain clinical value in raising the chance of successful examinations such as PTC and ERCP.
