Changes in gastric myoelectrical activity following highly selective vagotomy were studied in 12 patients by means of electrogastrography (EGG) using cutaneous electrodes. Measurements were made before, 10 days after, and six months after operation. Eight patients undergoing cholecystectomy served as controls. Preoperatively all controls and patients had normal recordings. In the cholecystectomized patients no significant changes were found postoperatively. Ten days after highly selective vagotomy the normal initial postprandial dip in gastric ECA frequency and the subsequent increase in frequency and power were not seen. Tachygastrias were observed in three patients. Six months after operation the normal frequency and power responses to a test meal had returned, but both the fasting and postprandial ECA frequencies were raised significantly. It is concluded that highly selective vagotomy is associated with abnormalities in myoelectrical activity, in particular in the postprandial state, most of which are reversible with time.
通过使用皮肤电极的胃电图（EGG）对12例患者进行了高选择性迷走神经切断术后胃肌电活动变化的研究。在手术前、术后10天和术后6个月进行测量。8例行胆囊切除术的患者作为对照。术前所有对照和患者的记录均正常。胆囊切除术后患者术后未发现明显变化。高选择性迷走神经切断术后10天，未观察到胃电活动频率正常的餐后初始下降以及随后频率和功率的增加。3例患者出现了心动过速。术后6个月，对试餐的正常频率和功率反应恢复，但空腹和餐后胃电活动频率均显著升高。结论是，高选择性迷走神经切断术与肌电活动异常有关，尤其是在餐后状态，其中大多数随着时间的推移是可逆的。
