A case of double pylorus.

Doubling of the pyloric channel is one of the rare anomalies of the intestinal tract. There have been 23 cases of double pylorus that we have been able to find in the literature. As the etiologic aspects of double pylorus the majorities of the cases were thought to be acquired lesions from ulcer disease except three cases. We present a case of double pylorus which seems to be acquired lesion, with a review of the literature.
