腹腔镜胃癌根治术相比传统开腹手术仍具有其一定的自身劣势,如丧失手的触觉。弥补这一劣势要求术者对腹部解剖更加熟悉,然而胃周结构相对复杂,尤其是血管解剖变异较大给术者加大手术难度。我们首次应用双源CT(dualsourceCT,DSCT)对腹腔镜胃癌手术术前血管评估,发现对于手术规划具有很大价值。报告如下。 Laparoscopic radical gastrectomy still has its own disadvantages compared to traditional laparotomy, such as the loss of touch. To make up for this disadvantage requires that surgeons be more familiar with abdominal anatomy, however, the structure of the stomach circumference is relatively complex, especially the larger anatomical variations of blood vessels to increase the difficulty of surgery. For the first time, we applied dual-source CT (DSCT) to evaluate the preoperative blood vessels of laparoscopic gastric cancer surgery and found that it is of great value for surgical planning. The report is as follows.
