BACKGROUND
The gastrocolic trunk of Henle has not been described in detail in context with right hemicolectomy. The aim of this study was to define the caliber, length and three-dimensional position of the gastrocolic trunk of Henle (GTH).
METHODS
We studied 10 fresh (<24 h) cadavers. A corrosion cast method was employed. Cold polymerized methylacrylate was injected into the superior mesenteric vein (SMV) and artery. GTH diameter, length and point of confluence with the SMV were assessed.
RESULTS
The GTH was present in all specimens originating from the confluence of the right gastroepiploic and superior-anterior pancreaticoduodenal veins. The GTH joined the SMV at an average distance of 2.2 cm (range, 1.6-3.2 cm) from the inferior pancreatic border and it coursed towards the right side in a ventral-cranial direction. The mean caliber and length of the GTH were 5.2 mm (range, 4.8-5.8 mm) and 16.1 mm (range, 10.1-20.7 mm), respectively.
CONCLUSIONS
The GTH is a short, medium-sized vessel of potential clinical significance with a consistent ventral-cranial direction.
背景
在右半结肠切除术的背景下，尚未对亨勒胃结肠干进行详细描述。本研究的目的是确定亨勒胃结肠干（GTH）的管径、长度和三维位置。
方法
我们研究了10具新鲜（<24小时）尸体。采用铸型腐蚀法。将冷聚合的甲基丙烯酸甲酯注入肠系膜上静脉（SMV）和动脉。评估GTH的直径、长度以及与SMV的汇合点。
结果
所有标本中均存在GTH，其起源于胃网膜右静脉和胰十二指肠上前静脉的汇合处。GTH在距胰腺下缘平均2.2厘米（范围1.6 - 3.2厘米）处汇入SMV，并沿腹侧头侧方向向右走行。GTH的平均管径和长度分别为5.2毫米（范围4.8 - 5.8毫米）和16.1毫米（范围10.1 - 20.7毫米）。
结论
GTH是一条短的、中等大小的血管，具有潜在临床意义，走行方向始终为腹侧头侧。
