title: [Studies of gastric motility following SPV and pyloroplasty in dogs (author's transl)].
abstract: 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).
