INTRODUCTION
The gastroesophageal junction is a complex anatomic area. Precise endoscopic assessment of the gastroesophageal junction is of utter importance, especially regarding Barrett's esophagus and neoplasms of the gastroesophageal junction. There has been a lack of a validated definition of the endoscopic gastroesophageal junction.
METHODS
Seven patients scheduled for resection of the gastroesophageal junction were included. Before surgery, gastroscopy was performed and the gastroesophageal junction was assessed. If there was disparity between the endoscopic gastroesophageal junction and the Z-line, the gastroesophageal junction was marked with India ink tattooing. Postoperatively the resection specimens were evaluated and the anatomical gastroesophageal junction was compared with the endoscopic.
RESULTS
In all seven patients the measured difference between the gastroesophageal junction and the endoscopic junction was <5 mm.
CONCLUSIONS
The upper margin of the longitudinal folds of the stomach can be used as an appropriate endoscopic definition of the gastroesophageal junction.
引言
胃食管交界是一个复杂的解剖区域。对胃食管交界进行精确的内镜评估至关重要，尤其是对于巴雷特食管和胃食管交界肿瘤。目前缺乏经过验证的内镜下胃食管交界的定义。
方法
纳入7例计划行胃食管交界切除术的患者。术前进行胃镜检查并评估胃食管交界。如果内镜下胃食管交界与Z线存在差异，则用印度墨水标记胃食管交界。术后评估切除标本，并将解剖学上的胃食管交界与内镜下的进行比较。
结果
所有7例患者中，胃食管交界与内镜下交界的测量差异均<5mm。
结论
胃纵向皱襞的上缘可作为胃食管交界合适的内镜定义。
