骨盆影像学测量在腹腔镜低位直肠癌术前评估中的应用进展

The application of pelvic imaging measurements in the preoperative evaluation of laparoscopic low colorectal cancer was reviewed

目前全球结直肠癌的发病率正在上升,而我国直肠癌患者中70%以上位于直肠中下段。由于骨盆解剖结构的限制性,低位直肠癌的手术难度大。随着外科手术的不断多样化,微创化,手术的安全性问题不断得到关注,而术前骨盆测量的重要性愈显突出。现本文就近年来骨盆测量的各个径线的意义及其对腹腔镜低位直肠癌的手术难易程度、环切缘、手术标本的完整程度及对低位直肠癌保肛手术的影响作一系统综述。

Nowadays,the global incidence of colorectal cancer remained on the rise, and more than 70%of colorectal cancer incidence in our Country（in China）is the low rectal cancer.Because of the restriction in pelvic anatomical structures,the low rectal surgery procedure has a great level of difficult.In line with constant progress on variety of surgery and minimally invasive techniques,issue of procedural safety has become the main focus,and pre-operative pelvic measurement（pelvimetry） has dearly become much more important.This article focus on indications of pelvic plane＇s lines and angle measurement in relation to level of difficulties in laparoscopic low rectal resection surgery procedure,the circumferential margin,the integrity of the post-operative specimen and rate of spinchter-saving low rectal resection.
