A study of the motor activity of the gastroduodenal (GD) junction has been carried out on 8 subjects by using an original probe provided with a suction cup, that allows not only a duodenogastric (DG) pull-though, but also a prolonged recording of the pyloric, antral and duodenal motor activity, in basal condition and after intraduodenal instillation of HCl 0.1 N and intravenous infusion of cerulein. The position of the probe was controlled with fluoroscopy and transmural potential difference. The DG pull-through did not show a zone of high pressure at the GD junction, but the prolonged study showed, during HC1 and cerulein administrations, a significant increase of the pyloric tonus.
通过使用一种配有吸盘的原创性探头，对8名受试者的胃十二指肠（GD）交界处的运动活性进行了研究。该探头不仅可以进行十二指肠-胃（DG）牵拉检查，还能在基础状态以及十二指肠内滴注0.1N盐酸和静脉输注雨蛙素后，长时间记录幽门、胃窦和十二指肠的运动活性。通过荧光透视和跨壁电位差来控制探头的位置。DG牵拉检查未显示GD交界处存在高压区，但长时间研究表明，在给予盐酸和雨蛙素期间，幽门张力显著增加。
