2:2 | Patient population
We identified all pregnant women who underwent appendectomy at South
Stockholm General Hospital between December 2015 and February 2021. As a
reference group to be able to compare pregnancy outcome, we identified
women giving birth without appendectomy giving birth during the same
time-period. Appendicitis rates were determined based on all pregnant
and non-pregnant women with appendectomy in the Stockholm region. For
comparisons of times and complication rates, we also identified a
control group of non-pregnant fertile women, aged 18 – 45 years
undergoing appendectomy.
