Abstract:
The seasonal periodicity of perforated peptic ulcer of the stomach was analysed among 296 patients operated at seven departments of gastrointestinal surgery in Denmark between 1975 and 1984. Admissions were significantly higher in August and September with a tendency, although not significant, in March also. This pattern was unaffected by age and sex.
