OIPD is a rare condition. In 1987, Levine et al detected this abnormality in 21 (0.15%) of 14 350 patients undergoing radiological examination of the oesophagus.1

Some authors postulate that the ductal dilatation results from duct obstruction by thick mucus, inflammatory material or desquamated epithelium.2 Others presume an extrinsic compression of the ducts by periductal inflammation and fibrosis that result from chronic oesophagitis. From 80% to 90% of the patients with OIPD had endoscopic and/or histological evidence of oesophageal inflammation.3 It is also not clear whether Candida is the cause of the chronic inflammation or represents just a secondary colonisation in areas of stasis.
