With the use of electromyography and intraluminal pressure recording of the pylorus, the effect of selective proximal and truncal vagotomy on the gastric motility was investigated in 10 dogs. The results are summarized as follows: 1. Control dogs showed regular discharge intervals with elevation of intrapyloric pressure coinciding with the action potentials. There was seen no occurrence of antiperistalsis. 2. Selective proximal vagotomy resulted in the prolongation of discharge intervals along with slight decrease in the incidence of action potentials. The rate of antiperistalsis was 4.4%. Besides, the rate of pyloric contraction also showed a tendency of slight decrease. 3. Truncal vagotomy lead to the prolongation of discharge intervals and decrease in the incidence of action potentials, though these changes were milder than those after selective proximal vagotomy. The incidence of antiperistalsis was 6.8% which was higher than the one after selective proximal vagotomy. Eelvation of intrapyloric pressure did not necessarily took place coinciding with the action potentials. Intrapyloric pressure as well as the incidence of pyloric contraction showed a marked decrease when compared with those of the control and selective proximal vagotomy dogs. Out of these results, it is concluded that the selective proximal vagotomy is superior to the truncal vagotomy when viewed from the preservation of the gastric motility.
通过使用肌电图和幽门腔内压力记录，对10只狗进行了选择性近端迷走神经切断术和迷走神经干切断术对胃动力影响的研究。结果总结如下：1. 对照犬表现出规律的放电间隔，幽门内压力升高与动作电位同时出现。未观察到逆蠕动的发生。2. 选择性近端迷走神经切断术导致放电间隔延长，动作电位发生率略有下降。逆蠕动发生率为4.4%。此外，幽门收缩率也呈轻微下降趋势。3. 迷走神经干切断术导致放电间隔延长，动作电位发生率降低，尽管这些变化比选择性近端迷走神经切断术后的变化要轻。逆蠕动发生率为6.8%，高于选择性近端迷走神经切断术后的发生率。幽门内压力升高不一定与动作电位同时发生。与对照犬和选择性近端迷走神经切断术犬相比，幽门内压力以及幽门收缩率均显著降低。从这些结果可以得出结论，从保留胃动力的角度来看，选择性近端迷走神经切断术优于迷走神经干切断术。
