Post-bulvar duodenal ulcer is a relatively rare disease, of which incidence is less than 5% among the whole gastrointestinal ulcers. We reported four cases of post-bulvar acute ulcers, followed after cardiovascular surgery.
In all case ulcers were observed as multiple, longitudinal, symmetric and band-shape, unlike peptic ulcers. Every patient had no characteristic basal disease and got recovered after oral administration of proton pump inhibitor (PPI) . Insufficient blood supply from pancreatico-duodenal artery, the initial feeder of this legion, might cause ischemic disorders by cardiovascular surgical procedures.
