[On the nature of secondary ulcers of the stomach].

The authors have studied two main groups of causes of the arising of secondary ulcers of the stomach: ulcerous aetiology due to stenosing duodenal ulcers (238 patients--81.1%) and non-ulcerous aetiology (53 patients--18.2%). It was found that both variants of secondary ulcers were characterized by a considerable part of so called "difficult" ulcers of the stomach and high bias towards bleedings. Operation of choice for secondary ulcers of the stomach must be resection of the stomach preferably by the Billroth-I method or application of termino-lateral anastomosis.
