upside down pylorus

ABSTRACT

A 40 year old clerk presented with chronic abdominal pain and dyspepsia ultrasonography showed a thick walled gall bladder with gall stones, barium meal examination showed an upside-down pylorus, a pylorus which is below, to the left, and anterior to the normal position of the pylorus. This was an incidental finding and had no practical significance as the symptoms resulted from chronic calculous cholecystitis. Such a positional anomly of the pylorus is congenital. The literature have also been reviewed
