It has been reported that there are four zones of distinct venous patterns around the gastroesophageal junction (GEJ); i.e. truncal, perforating, palisade (PZ) and gastric zones. Using the distal end of PZ as a marker for GEJ, this study was done to assess the length and patterns of PZ in Koreans, and to assess the prevalence of endoscopic Barrett's esophagus (E-BE) and hiatal hernia (E-HH).
847 consecutive patients undergoing diagnostic endoscopy were included. During endoscopy, PZ, squamocolumnar junction (SCJ) and pinchcock action (PCA) were identified. Patterns were classified according to the relationships of the distal end of PZ with SCJ and PCA; A: all three at the same level, B: SCJ proximal to the other two which are at the same level, C: PCA distal to the other two which are at the same level, D: SCJ proximal to the distal end of PZ which is proximal to PCA. Cases with patterns B and D were thought to have E-BE, and those with patterns C and D to have E-HH.
Patterns A, B, C and D were 79.2%, 12.1%, 3.8% and 4.9%, respectively. Length of PZ was 3.0 +/- 0.1 cm. E-BE and E-HH were found in 17.0% and 8.7%, respectively. Both E-BE and E-HH were more frequently found in males and in cases with reflux esophagitis.
E-BE and E-HH are not so infrequent in Koreans as previously thought, if we use the distal end of PZ as an endoscopic marker of GEJ.
据报道，在胃食管交界（GEJ）周围存在四个不同静脉模式的区域，即主干区、穿支区、栅栏状（PZ）区和胃区。本研究以PZ远端作为GEJ的标志物，旨在评估韩国人PZ的长度和模式，并评估内镜下巴雷特食管（E - BE）和食管裂孔疝（E - HH）的患病率。
纳入847例连续接受诊断性内镜检查的患者。在内镜检查过程中，识别PZ、鳞柱状交界（SCJ）和夹闭动作（PCA）。根据PZ远端与SCJ和PCA的关系对模式进行分类：A：三者处于同一水平；B：SCJ位于其他两者同一水平的近端；C：PCA位于其他两者同一水平的远端；D：SCJ位于PZ远端的近端，而PZ远端位于PCA的近端。模式B和D的病例被认为患有E - BE，模式C和D的病例被认为患有E - HH。
模式A、B、C和D分别为79.2%、12.1%、3.8%和4.9%。PZ的长度为3.0±0.1厘米。E - BE和E - HH的患病率分别为17.0%和8.7%。E - BE和E - HH在男性以及反流性食管炎患者中更为常见。
如果我们将PZ远端用作GEJ的内镜标志物，E - BE和E - HH在韩国人中并不像之前认为的那样罕见。
