Abstract

Unlabelled: In unanesthetized dogs, the mechanical activity of the antrum and pylorus was studied by means of strain gauge force transducers during fasting condition, after feeding, and following application of metoclopramide (Paspertin), before and after SPV without pyloroplasty, and after SPV with pyloroplasty respectively.

Results: 1) The mechanical activity during fasting condition differs from that after feeding. 2) During fasting, the contractile force is decreased for about 15%-20% after SPV without pyloroplasty and for about 50% after SPV with pyloroplasty. The frequency remains unchanged. 3) After feeding, the contractile force is decreased by about 50%, the frequency shows an increase of 100%. The same results can be obtained after SPV with or without pyloroplasty. 4) After metoclopramide the contractile force is increased up to 30%, during fasting, after feeding, and also before and after SPV. The frequency, however, shows no significant change. 5) The postoperative findings remained unchanged throughout the entire observation period (up to the 20th postoperative month).

[犬SPV和幽门成形术后胃运动的研究[作者简介]。

未标记:在未麻醉的犬中，分别在禁食状态、进食后、应用甲氧氯普胺(Paspertin)后、未幽门成形术的SPV前后和SPV合并幽门成形术后，通过应变式力传感器研究了胃窦和幽门的机械活动。结果:1)空腹与进食后的机械活性存在差异。2)空腹时，未进行幽门成形术的SPV术后收缩力下降约15%-20%，幽门成形术后SPV术后收缩力下降约50%。频率保持不变。3)进料后，收缩力下降约50%，频率增加100%。SPV合并幽门成形术或不合并幽门成形术均可获得相同的结果。4)甲氧氯普胺后，在禁食期间、进食后以及SPV前后，收缩力均增加30%。然而，频率没有明显变化。5)在整个观察期(直至术后第20个月)，术后结果保持不变。
