Electromyographical studies were made on the gastric motility of dogs following selective vagotomy (SV) and selective proximal vagotomy (SPV) as the subsequent studies on the changes after truncal vagotomy (TV) after which gastric motility is fairly disturbed, and the influence of pyloroplasty additionally performed to SPV. Gastric discharge frequency was suppressed by SV similar to that by TV. Dysrhythmia of motility occurred after gastric vogotomy. Restoration to the normal was the fastest after SPV. Changes in the discharge frequency after SPV did not differ much from those in the normal stomach and other types of vagotomy. With SPV, the decrease in the propagation velocity of basic electrical rhythms (BER) was mild, and a pattern similar to the control was shown compared with TV and SV. The antiperistaltic discharge was observed even with SPV, but the frequency was low compared with TV and SV. The frequency of peristaltic discharge was the highest when pyloroplasty was performed in addition to SPV. The responses to vagostigmine, insulin tetragastrin in SPV were similar to those in the normal stomach. During the gastric emptying time, there was neither difference before and after SPV, nor any significant difference due to the presence or absence of pyloroplasty. The above data show that SPV is advantageous for retaining the function of gastric peristalsis, also for gastric secretion, but the addition of pyloroplasty will not be advantageous for the elimination of gastric content.
对狗进行选择性迷走神经切断术（SV）和选择性近端迷走神经切断术（SPV）后，进行了肌电图研究，后续还研究了全胃迷走神经切断术（TV）后胃动力受到相当大干扰的变化情况，以及额外对SPV施行幽门成形术的影响。SV对胃排空频率的抑制作用与TV相似。胃迷走神经切断术后出现了动力性心律失常。SPV后恢复正常的速度最快。SPV后放电频率的变化与正常胃及其他类型迷走神经切断术的变化差异不大。对于SPV，基本电节律（BER）的传播速度下降轻微，与TV和SV相比，显示出与对照组相似的模式。即使是SPV也观察到了逆蠕动放电，但与TV和SV相比频率较低。当在SPV基础上施行幽门成形术时，蠕动放电频率最高。SPV对迷走神经兴奋药、胰岛素和五肽胃泌素的反应与正常胃相似。在胃排空时间方面，SPV前后没有差异，有无幽门成形术也没有任何显著差异。上述数据表明，SPV有利于保留胃蠕动功能，也有利于胃分泌，但施行幽门成形术对清除胃内容物并无益处。
