Barrett食管(Barrett’s esophagus,BE)是指食管下段的复层磷状上皮被有肠化的单层柱状上皮所替代的一种病理现象,又名柱状上皮细胞食管。Barrett食管是一种癌前病变状态,其发生食管癌的危险性较一般人群高30~50倍,发生率为每年1/150[1]。此类患者一般需终身内镜监测以早期检出
Barrett’s esophagus (BE) is a pathological phenomenon in which the lamina propria of the lower esophagus is replaced by an intestinal metaplastic columnar epithelium, also known as the columnar epithelial cell esophagus. Barrett’s esophagus is a precancerous condition with a 30- to 50-fold higher risk of esophageal cancer than the general population, with an incidence of 1/150 per year [1]. Such patients generally require lifelong endoscopy to detect early detection
