  • Title: [The effect of pyloric stenosis on the development of stress ulcers in the rat].
    Author: Schramm H, Rupprecht H, Schäfer F.
    Journal: Z Exp Chir; 1977 Apr; 10(2):75-8. PubMed ID: 871054.
    Abstract:
    The authors examined in rats the importance of pyloric stenosis for the development of spontaneous acute ulcers and stress ulcers in the stomach. Spontaneous superficial lesions arise only during the first 20 days. They apparently signify an intensified narrowing by postoperative swelling with mechanical stimulation of gastrin secretion in the antrum. They were not observed during later periods. Chronic ulcers did not develop. Stress ulcers caused by immobilization were more frequently seen in rats with pyloric narrowing than without. Vagotomy protected the rats with pyloric stenosis from stress ulcer, although not as certain as in control animals.
