摘要
目的探索胃壁内迷走神经和血管的分支分布。方法改良的Sihler’s染色法。结果迷走神经前、后干在贲门附近分别发出2条和3条初级神经支,其中胃前支与胃后支主要集中在贲门至角切迹之间发出次级支,在胃壁呈扇形分布。胃后壁胃体部的分支及分支间吻合比胃前壁密集。胃前、后支在贲门附近的小弯侧有交通支,在大弯侧有广泛吻合。各动脉血管支从胃壁进入肌层深面,分支分布类似地图上的交通路线。胃前壁上血管分支相对后壁少,粗大,形成了胃体近端和幽门部两个密集分布区;胃后壁在胃底部和胃体中部分布密集。胃壁内血管有干吻合和细支吻合。胃小弯与幽门口区属于相对乏血管区。结论为适应胃运动、调节胃酸分泌等功能需要,胃的神经血管分布不均匀,存在密集分布区与稀疏区。
Objective To investigate branches and distribution of vagus nerves and arteries in human stomach wall. Methods Modified sihler＇s neural staining. Results The anterior and posterior vagal trunk was divided into 2 and 3 primary branches at cardiac neighborhood respectively. Among them, the anterior and posterior gastric branches given off second branches between cardia and angular incisure mainly, their distribution was sectorial in stomach wall. Branches and anastomoses in body of stomach, anterior stomach wall much dense than posterior. There were communicating branches at cardiac neighborhood of lesser curvature between anterior and posterior gastric branches. There were many anastomoses at greater curvature. Artery branches entered into profundal tier of stomach wall muscle, their branches and distribution resembled traffic way on map. Artery branches in anterior stomach wall lesser and crassituded than posterior, there were 2 dense areas in proximal stomach body and pyloric part respectively. There were 2 dense areas in fundus and middle body. Artery branches in stomach wall had trunk and thin anastomoses. Lesser curvature of stomach and pylorus was relative lack vessel. Conclusion For accommodating locomotion and regulating the secretion of gastric acid, the distribution of nerves and arteries in stomach wall were asymmetry, existed as dense and sparse area.
