Seasonal variation of acute appendicitis: a 56-year study.
Over a period of 56 years, 12,686 appendectomies were done for acute appendicitis at the Jersey City Medical Center in Jersey City, New Jersey. We tabulated each appendectomy by the month and season of its occurrence. The spring and summer months had the highest incidence and the fall and winter the lowest. Using analysis of variance, however, we found no statistically significant variation in incidence.
