食管黏膜下血肿的CT检查特征

Features of computed tomography examination of esophageal submucosal hematoma

食管黏膜下血肿临床上较少见,缺乏典型临床表现,行胃镜检查可能二次损伤食管黏膜导致患者大出血,CT检查具有检查速度快、成像迅速及无创伤等特点,有助于该病的诊断与鉴别诊断.本研究回顾性分析2005年7月至2014年2月浙江省乐清市人民医院、温州医科大学附属第一医院、郑州大学医学院附属第一医院和浙江省温州市第三人民医院共收治的9例食管黏膜下血肿患者的临床资料.食管黏膜下血肿范围≥2段食管,食管黏膜撕裂口起止均位于食管生理性狭窄处,食管增粗、管腔狭窄,食管壁呈环形或偏心性增厚,食管腔呈新月形、斑点样或裂隙样气腔影,血肿的密度随出血时间延长逐渐由高降低是食管黏膜下血肿CT检查的影像学特征,对该病的及时诊断具有重要价值.

Esophageal submucosal hematoma is rarely seen in clinical practice and its clinical presentations are untypical.Gastroscopy might injure the esophageal mucosa and cause bleeding.Computed tomography had the advantages of quick examination and formation of imaging,as well as non-invasiveness,which is helpful for the diagnosis and differential diagnosis of the esophageal submucosal hematoma.The clinical data of 9 patients with esophageal submucosal hematoma who were admitted to the Yueqing People＆#39;s Hospital,the First Affiliated Hospital of Wenzhou Medical University,the First Affiliated Hospital of the Zhengzhou University and the Third People＆#39;s Hospital of Wenzhou from July 2005 to February 2014 were retrospectively analyzed.The features of computed tomography examination of esophageal submocosal hematoma include the range of the esophageal submucosal hematoma exceeds 2 parts of the esophagus,the rip of the esophageal mucosa begins and ends at the physiological narrowing of the esophagus,thickening of the esophageal wall,stricture of the esophagus,annular thickening and eccentric thickening of the esophageal wall,crescent,spot or gas shadows of the esophageal cavity,the density of the hematoma decreases as the time passed by.These features of computed tomography are of great importance for the diagnosis of esophageal submucosal hematoma.
