现提倡对Barrett食管患者定期作内镜和活检监测以早期发现癌变。本文研究的目的之一是确定内镜和活检监测对发现Barrett食管发生早期腺癌的有效性;其二是对内镜下未见肿块的因高度发育不良(HGD)或早期腺癌而切除的食管作详细病理学研究。研究分2组:第1组为行胃十二指肠内镜检查的相继病例,内镜示Barrett食管,无明显癌肿,活检为HGD;第2组为内镜见Barrett食管,无明显癌肿,而活检显示早期癌变。标准内镜监测计划为对Barrett食管
Endoscopic and biopsy surveillance of patients with Barrett’s esophagus is now being advocated for the early detection of canceration. One of the purposes of this study was to determine the effectiveness of endoscopic and biopsy monitoring in the detection of early adenocarcinoma of the Barrett’s esophagus; the second is to remove high-grade dysplasia (HGD) or early adenocarcinoma from endometrial tumors without lumps. The esophagus was studied for detailed pathology. The study was divided into two groups: the first group consisted of successive cases of gastroduodenal endoscopy. The endoscopic Barrett’s esophagus showed no cancer and the biopsy was HGD. The second group was Barrett’s esophagus with no obvious cancer. Swelling, while biopsy shows early canceration.
