RELACIÓN ENTRE LA ECOGRAFÍA Y ANATOMOPATOLOGÌA EN LA APENDICITIS AGUDA EN EL HOSPITAL LUIS VERNAZA 2014- 2016

Abstract

Introduction: Acute appendicitis is a very common pathology in emergency services worldwide, which requires quick and accurate decision making to avoid complications. Abdominal ultrasound has become a very useful tool in the management of patients with abdominal pain. Ultrasound can establish the diagnosis of acute appendicitis, but above all, show complications and eliminate differential diagnoses. Objectives: To establish the correlation of ultrasound and pathology in the diagnosis of acute appendicitis. Histopathologically, the cases of acute appendicitis are present. To determine the value of ultrasound as the method of acute appendicitis. Correlate the ultrasound findings with the histopathological diagnosis in acute appendicitis. Methods and materials: The present study was a retrospective, nonexperimental descriptive study performed in the patients of the Hospital de Lucha with the diagnosis of acute appendicitis in the emergency department. Data tabulation and analysis are performed using the statistical program Microsoft Office Excel 2010 program. Results: Ultrasound showed a sensitivity of 68.8%, specificity of 40%, predictive value of 91.1%, negative predictive value of 12.5%, false positives Of 6%, false negatives of 28%, a value p: 0.5, and a chi-square value of 0.32. : Of the 100 patients that participated in the study, 43 (43%) presented Fibrinopurulent phase, 26 (26%) Necrotica, 15 (15%) Catarral and 6 (6%) Perforated and 10 (10%) without alterations. Conclusions: Ultrasonography is a rapid and inexpensive method in the diagnosis of acute appendicitis presents a high sensitivity but low specificity and should be interpreted with great caution in patients with classic symptomatology
