目前已公认近端胃迷走神经切断术(又名胃壁细胞迷走神经切断术或高选择性迷走神经切断术)治疗十二指肠溃疡有效.但是手术必须完全切断胃酸分泌区的神经,而保留运动区的神经,才能减少胃酸的过度分泌又不影响胃的排空.因此明确胃窦和胃体之间的分界线就很重要.目前一般可用三种方法来定位:第一种方法是测定胃体粘膜与胃窦粘膜pH值的差别,以确定二者的分界线.第二种方法是根据解剖标志在术中辨认出拉氏神经鸦爪支的近端界限,切断近
It is currently accepted that proximal gastric vagotomy (also known as gastric parvulus vagotomy or highly selective vagotomy) is effective for the treatment of duodenal ulcers, but surgery must completely cut off the nerves in the gastric acid secretion zone while retaining the nerves in the motor area. In order to reduce excessive gastric acid secretion without affecting the emptying of the stomach, it is important to clarify the dividing line between the antrum and the stomach body. Currently, there are generally three methods to locate: The first method is to measure the gastric mucosa and The difference in the pH of gastric antrum mucosa to determine the boundary between the two. The second method is based on anatomical landmarks in the operation to identify the proximal boundary of the Raven Chuck’s claw branch, cut off near
