ABSTRACT

Double pylorus is a rare abnormality and it occurs most commonly secondary to chronic peptic ulcer disease. Smith and Tuttle described in 1969 for the first time a double pylorus. The pathogenesis is still discussed the anomaly may be congenital or acquired. The entity of double pyloric channels may be congenital but the majority are acquired lesions representing fistulae secondary to peptic ulcer disease in the pyloroduodenal region. Radiologic appearances may be confused with an antral carcinoma, an ulcerating carcinoma, Crohn’s disease, or lymphoma. It is usually treated conservatively with anti-ulcer therapy. However, refractory cases may require surgery. A case of acquired double pyloric channel in a 78-year-old man is reported, with a review of the available literature on the topic.
