Application Of Preoperative Identification Of Henle Trunk By Three-dimensional Multidetector Computed Tomography In Laparoscopic Right Hemicolectomy

ObjectiveThe aim of this study is to describe the anatomical variations of the Henle trunk detected by three-dimensional multidetector computed tomography and to explore the applications in laparoscopic right hemicolectomy.MethodsEighteen patients who underwent laparoscopic right hemicolectomy were retrospectively reviewed,whose Henle trunk was detected by three-dimensional multidetector computed tomography.ResultsThe Henle trunk was identified in all the patients by three-dimensional multidetector computed tomography.The Henle trunk described by three-dimensional multidetector computed tomography was classified into three types,Type-0(no colic drainage vein)?Type-I(one colic drainage vein)and Type-II(two colic drainage veins),based on the number of drained colic veins(superior right colic vein,right colic vein and middle colic vein).The frequencies of Type-0?Type-I and Type-II were 5.4%(n=2)?70.3%(n=26)and 24.3%(n=9),respectively.ConclusionsThree-dimensional multidetector computed tomography can clearly identify the anatomical variations of the Henle trunk,which can provide guidance to laparoscopic right hemicolectomy.
