Song, Kim, Jeong, Heo, Shin, Kang, and Heo: Double Pylorus After a Peptic Ulcer in the Gastric Antrum: A Case Report

Abstract

Double pylorus is an accessory channel between the gastric antrum and duodenal bulb with a normal pyloric canal. It is understood that the etiology of double pylorus is a congenital anomaly or an acquired complication after the occurrence of peptic ulcer disease. We report the CT findings with CT gastrography of double pylorus as a complication after a previous peptic ulcer in the gastric antrum.

Fig. 1. Double pylorus as a complication after previous peptic ulcer in the gastric antrum in a 54-year-old man.

A. Endoscopic image shows the peptic ulcer (white arrowhead) in the lesser curvature of gastric antrum and the pyloric canal (arrow).
B. 2D axial CT image shows a normal pylorus (arrow) and abnormal channel (arrowhead) between gastric antrum and duodenal bulb.
C. CT gastrogram shows double orifices of a normal pylorus (arrow) and abnormal channel (arrowhead) in the gastric antrum.
D. After 4 months, follow up endoscopic image shows the upper abnormal channel (black arrowhead) between the gastric antrum and duodenal bulb at the same site of a peptic ulcer on previous endoscopic image, and the lower true pyloric canal (arrow).
E. Image of upper gastrointestinal series (after 2 months) shows the upper abnormal channel (arrowhead) in the lesser curvature between gastric antrum and duodenal bulb and the lower true pyloric canal (arrow).
