Characteristics of the early gastroesophageal junction cancer under the white-light endoscopy / 实用医学杂志

ABSTRACT

Objective To investigate the characteristics of the early gastroesophageal junction(GEJ)can-cer under the white-light endoscopy.Method We analyzed 70 cases of pathology-proven early GEJ cancer retrospec-tively. We investigated the predilection sites of different Siewert types,the lesion features under the white-light endoscopy,and the associations among the Siewert types,Barrett esophagus and the intestinal metaplasia. Results Siewert Ⅱ was the most of the early GEJ cancer(64%). Barrett esophagus was the most of SiewertⅠ(85%).No statistical significances of the intestinal metaplasia were found among different Siewert types.SiewertⅠlesion was located on the right front wall the most.Of Siewert Ⅱlesion was located on the back wall the most.The main endoscopic type was Type 0~Ⅱ.The most of the early GEJ cancer under the white-light endoscopy has clear demarcation(89%)and irregular surface appearance(81%),and the main color of mucosa lesion was red(76%). Conclusion The early GEJ cancer under the white-light endoscopy shows the subtle characteristic changes.Under-standing and paying attention to the above characteristics will help to improve the diagnosis of the early GEJ cancer.
