title: Acquired double pylorus.
abstract: We have reported two cases of double pylorus or duplicated pyloric channel as an unusual complication of peptic ulcer disease. It is usually noted as an incidental finding on x-ray films or at endoscopy. Double pylorus seems to be an acquired lesion arising from gastric ulceration and does not necessarily require surgical correction.
