[Rare causes of pyloric stenosis]

In the introduction the author deals with the genesis, symptoms and treatment of pylorostenosis. He presents then several interesting cases from his 30 years' surgical material which had an uncommon pathogenesis. The latter was congenital, several times inflammatory, traumatic, lithogenic and tumorous. Consistent with data in the literature, he recommends early surgical treatment of benign gastric lesions as well as optimal prevention of severe complications.
