title: The aetiology of gastric stump carcinoma in the rat.
abstract: This study investigated the aetiology of gastric stump carcinoma in the rat. These carcinomas were induced by duodenogastric reflux without the need to administer carcinogens. Carcinoma was only detected when pancreatic exocrine secretions were present in the reflux. Malignant change was associated with dysplasia but not intestinal metaplasia or adenocystic proliferation of glands. The extent of resection increased tumour yield, but a truncal vagotomy did not. No difference was detected in intragastric pH, bacterial flora, or bile acid concentration between animals with and without carcinoma.
