Aim and Objectives: To study the diagnostic value of individual ultrasonographic signs in acute appendicitis

Background and Purpose: This study aims to assess the diagnostic value of individual sonographic signs in acute appendicitis, primarily looking at the indirect signs. The secondary objectives are to look at the diagnostic value of direct signs, to provide an ultrasound probability criteria for appendicitis and also to retrospectively look at clinical scoring, Mantrel’s score in those cases where it is available.

Materials and Methods: 1) Analytical study. 2) The study will be conducted for 12 months at the Department of Radio-diagnosis, ASRAM Hospital, Eluru. 3) Phillips affinity 70G Ultrasound machine

Results: Out of 62 cases referred to radiology for emergency Ultrasound Abdomen prior to emergency appendectomy At least one indirect sign was positive in 98.4% (61) of the cases. At least 2 indirect signs were positive in 95.2% of the cases. At least 3 indirect signs were positive in 77.4 % of the cases. Only 1 case had no indirect sign positive. All 8 signs were positive in no cases. At least 1 direct sign was positive in 91.9 % of the cases and at least 2 direct signs were positive in 90.3 % of the cases. At least 3 direct signs were positive in 66.1% of the cases.

Conclusion: This study showed more than 90% of the cases referred to radiology for emergency Ultrasound Abdomen prior to emergency appendectomy had at least 1 Indirect and 1 Direct signs positive on Ultasound abdomen.
