Patients on systemic steroid therapy are at increased risk of diffuse
peritonitis, specially from gastrointestinal perforation. We performed
a retrospective study of 37 patients on systemic steroid therapy who
underwent surgery for diffuse peritonitis, Clinical presentation of pe
ritonitis was usually aspecific, making the diagnosis difficult. The m
edian interval between onset of symptoms and surgery was 3.3 days, red
uced to 2.0 days between hospitalization and surgery, The mortality ra
te was 46% (17 of 37 patients). We emphasize aggressive diagnostic eff
orts and early abdominal exploration in front of any persisting abdomi
nal pain in patients on systemic steroid therapy.
