逆行高选迷走神经切断的研究

Experimental study of retrograde selec-tive vagotomy

高选择性迷走神经切断术（ＨＳＶ）后溃疡复发率高的原因：①迷走神经的解剖变异；②手术操作困难。均可导致胃底、体神经的分支切断不完全。针对该原因我们设计一改进ＨＳＶ，１９９０年９月起实验研究，采用ＨＲＰ神经逆行追踪等方法证明设计手术切断胃底、体迷走神经支配完全，胃窦“鸦爪”支迷走神经保留完好。

The reasons for high relapse rate of ulcerare 1.the anatomic variation of vagus nerve;2.incomplete cutting of vagus nerve due to thedifficulty of operation. We designed a modifiedhigh selective vagotomy from and fromSeptember, 1990 conducted the experimentalstudy on 22 dogs. The HRP nervous retro-grade tracing on the postoperative dogsshowed complete cutting of nerve branches tothe fundus and the body and good conserva-tion of function of the antral claws nerves.
