Popis: The seasonal pattern of endoscopically diagnosed duodenal ulcer disease in an endoscopy unit in Suba University Hospital and Ibn Sina Hospital, Sudan, was evaluated retrospectively for the period 1980-1988. We reviewed all the 12443 endoscopy records and found 1348 cases of duodenal ulcers. The incidence of duodenal ulcer was then calculated for each month separately. We found that in Sudan the frequency of duodenal ulcer is significantly higher during winter (January-February), and significantly lower during summer (May-August).
