The ligament of Treitz suspends the distal duodenum but it has not been identified on abdominal CT scans. Duodenal displacement by an extrinsic mass is not an uncommon finding and is not prevented by the ligament of Treitz. The purpose of this study was to evaluate the size and strength of the ligament of Treitz in autopsy cases and then its visibility on abdominal CT scans. The ligament of Treitz was examined in 18 autopsy cases. The ligament was studied in situ and dissected for macro and micro examination. Size, shape and strength of the ligament were studied. Following the autopsy examination, upper abdominal CT scans were reviewed to identify the ligament. The Ligament of Treitz is a thin membranous and weak structure varying in size and shape. It would not be recognized on a CT image. It would not prevent displacement of the duodenum by an extrinsic mass. Illustrations of the ligament of Treitz in anatomic textbooks often represent an inaccurate picture of the true size and relationship of the ligament to adjacent structures.
Treitz韧带悬吊十二指肠远端，但在腹部CT扫描中未发现其显影。十二指肠被外在肿物推移并非罕见表现，且Treitz韧带并不能阻止这种情况发生。本研究旨在评估尸检病例中Treitz韧带的大小和强度，以及其在腹部CT扫描中的显影情况。对18例尸检病例的Treitz韧带进行了检查。在原位对韧带进行研究，并解剖以进行宏观和微观检查。研究了韧带的大小、形状和强度。尸检检查后，回顾上腹部CT扫描以识别韧带。Treitz韧带是一种薄的膜状且薄弱的结构，大小和形状各异。在CT图像上无法识别。它不能阻止十二指肠被外在肿物推移。解剖学教科书中Treitz韧带的图示往往不能准确呈现该韧带的真实大小及其与相邻结构的关系。
