Возможности ультразвукового исследования в диагностике деструктивных форм острого аппендицита

Abstract

The number of patients with acute appendicitis does not tend to decrease, which requires an improvementin the diagnosis of acute appendicitis. The incidence of unreasonable appendectomies reaches 35–40%,there remains a high percentage (32.3–50%) of postoperative complications (abscesses, infiltrates,peritonitis, etc.). In the diagnosis of acute appendicitis, laparoscopy is widely used, the diagnostic value ofwhich reaches 77.7–98.6%. But it has a number of known contraindications. On the contrary, ultrasound isnot only a non-invasive method, but also allows you to visualize acute appendicitis in its atypical locations,the degree of destruction of its wall and determine the exact localization in the abdominal cavity. Oneof the advantages of ultrasound is that it is a safe, non-invasive diagnostic method, it allows performingmultiple studies with the possibility of dynamic research without any burden on the patient and has nocontraindications. In the early stages of inflammation of the wall of the appendix, there is a low reliabilityof ultrasound (50–63.3%), with destructive forms it reaches 92–96%.
