A Novel Appendicitis TriMOdal Prediction Score (ATMOS) for Acute Appendicitis in Pregnancy: a Retrospective Observational Study

Acute appendicitis (AA) is a disease of younger age, but it occurs in 1 out of 500-2000 pregnancies. The current treatment of choice for AA in pregnancy is surgical. Even with standard clinical examination, serum inflammatory markers, and transabdominal ultrasound, the decision on surgical treatment of acute appendicitis (AA) and the rate of negative appendectomy in pregnancy are still unsatisfactory. There are several scoring systems (Alvarado, Tzanakis) that help making decision on operating more easier, however their specificity is either high with low sensitivity, or the other way around. In addition, all scores are based on adult non-pregnant population. We are making an observational study to develop a scoring system that would include ultrasonic imaging with clinical-biochemical parameters while not compromising sensitivity and specificity.
