Abstract

Objective: Knowledge of the anatomy of the stomach and its surrounding structures is essential for lymph node dissection. This is the first gross anatomical investigation of anastomosis variations in the gastroepiploic arteries (GEA). The aim of this study is to examine the anastomosis pattern of the right and left GEA (RGEA and LGEA, respectively).

Methods: Seventeen cadavers were dissected, and the anastomotic patterns of RGEA and LGEA were observed macroscopically.

Results: The anastomotic patterns were classified into two groups. Type 1 had direct anastomosis (n = 16; 94.1%), whereas Type 2 had no anastomosis (n = 1; 5.9%). Formation of an arterial arch along the greater curvature was observed in twelve cases (70.6%), whereas four cases (23.5%) exhibited mesh-like anastomosis or narrow anastomotic branches.

Conclusions: Direct anastomoses were observed in almost all the cases. These results are significant, and may be useful in the classification of lymph nodes or speculation of cancer metastases.

胃网膜动脉的解剖与外科评价。

目的:了解胃及其周围结构的解剖学知识对淋巴结清扫至关重要。这是胃大网膜动脉(GEA)吻合变异的首次大体解剖学研究。本研究的目的是检查右、左GEA(分别为RGEA和LGEA)的吻合模式。方法:解剖17具尸体，观察RGEA和LGEA的吻合形态。结果:吻合方式分为两组。1型直接吻合(n = 16;94.1%)， 2型无吻合(n = 1;5.9%)。12例(70.6%)出现动脉弓沿大曲度形成，4例(23.5%)出现网状吻合或吻合支狭窄。结论:几乎所有病例均采用直接吻合。这些结果是有意义的，并且可能对淋巴结的分类或癌症转移的推测有用。
