  • Abstract
  • Look Inside

 A case of double pylorus is reported, with illustrations of the radiological, endoscopical, and histological characteristics. As far as can be ascertained, a complete review of the literature (60 cases) is given. Both possible genetic mechanisms of this formation are discussed in detail; primary or congenital, and secondary or acquired by inflammation.

 After analysis of the histology of the pyloric bands of the hitherto related 12 surgical cases, the opinion is expressed that the so-called double pylorus represents an acquired form of peptic deformity. We think trans-sphincter tunnel formation of the prepyloric ulcer makes the pyloric band, containing gastroduodenal mucosa and smooth muscle.
