CT影像技术在腹内疝诊断中的应用

Application of CT imaging in diagnosis of internal hernia

腹内疝是一种脏器或组织通过间隙疝出的疾病,临床上缺乏特异性症状,预后较差.腹内疝按照解剖学分类,可以分为十二指肠旁疝、网膜孔疝、经肠系膜疝、肠系膜裂孔疝等.目前各种影像手段中,多层螺旋CT对于腹内疝的术前诊断有较高的价值.本文综述几种腹内疝在的多层螺旋CT扫描的影像特征,腹内疝的一般性诊断思路,以利于对腹内疝进行术前诊断.

Internal hernia is the protrusions of the viscera through the peritoneum or mesentery in the abdominal cavity.It lacks specific clinical symptoms and has a poor prognosis.According to the anatomical classification,the intra-abdominal hernia can be divided into Duodenal paralysis,Winslow hernia,mesenteric hernia and mesenteric hiatal hernia.Among various imaging methods,multi-slice spiral CT has a higher value for preoperative diagnosis of internal hernia.This article will focus on the imaging features of several intra-abdominal hernias under multi-slice spiral CT,and summarize the general diagnostic strategies of internal hernia.
