The intragastric distribution of a radionuclide labelled liquid meal was studied in 62 patients with duodenal ulceration by means of a gamma camera imaging system. A total of 85 gastric emptying studies (23 preoperative and 62 postvagotomy tests) revealed three distinct patterns of distribution. The activity distribution in the stomach after vagotomy showed a slower rate of return and a decreased accumulation of the meal in the proximal part of the stomach compared with the pattern in the intact stomach. The return of the liquid meal to the proximal stomach was considered to be a physiological process controlled by vagal reflexes and changed by a vagotomy. These observations made during emptying of a liquid meal seem to give rise to a better differentiation of the motor patterns after various types of gastric operations. With a quantification of the intragastric patterns of distribution it may be possible in a prospective study to give a more graded evaluation of changes induced by vagotomy than is possible with the traditional characterisation of gastric emptying.
通过γ相机成像系统，对62例十二指肠溃疡患者放射性核素标记液餐在胃内的分布情况进行了研究。总共进行了85次胃排空研究（23次术前和62次迷走神经切断术后测试），揭示了三种不同的分布模式。与完整胃的模式相比，迷走神经切断术后胃内的活性分布显示返回速率较慢，且胃近端餐食的积聚减少。液餐返回胃近端被认为是一个受迷走神经反射控制且因迷走神经切断术而改变的生理过程。在液餐排空过程中所做的这些观察，似乎能更好地区分各种类型胃部手术后的运动模式。通过对胃内分布模式进行量化，在前瞻性研究中，可能比传统的胃排空特征描述更能对迷走神经切断术引起的变化进行更分级的评估。
