Role of Ultrasonography in the Diagnosis of Acute Appendicitis

Introduction: Acute appendicitis is still prevalent as a major surgical emergency. Due to the fast progress of the ailment, surgery is often the most sensible approach to manage it. But any surgery comes with its fair share of risk. If the diagnosis of the disease can be made more accurate prior to surgery, the error rate of negative appendectomy can be greatly reduced. Aim of the study: The aim of the study was to evaluate the role of ultrasonography in the diagnosing acute appendicitis. Methods: This prospective cross-sectional study was conducted at the Institute of Nuclear Medicine & Allied Sciences (INMAS), Rangpur with Department of Surgery & Department of Pathology of Rangpur Medical College Hospital, Rangpur, Bangladesh. The study duration was 02 years, from 01January 2022 to 31 December 2023. A total of 100 cases were selected from those patients were come for ultrasound examination, send from the hospital with pain in the right lower quadrant of the abdomen for the purpose of this study. Result: Among the 100 participants of the study, histopathological diagnosis showed that 86% were acute appendicitis cases and 14% had normal appendicitis. Gender or age had no significant association with histopathological diagnosis, but male prevalence was observed in the study, with a high prevalence of young adults. The original site of pain was periumbilical pain shifted to the right iliac fossa for half the participants. Pain duration was between 18-24 hours for 36% of the cases. All participants presented with pain, fever, anorexia, and nausea had a high prevalence among participants. The sensitivity and specificity of high-resolution ultra-sonogram were 84.9% and 85.7% respectively. Conclusion: Appendicitis is a disease of the young, and can occur in participants of both genders. Histopathological diagnosis has no significant association with patient age or gender. Ultra-sonogram has high sensitivity and specificity ratio in diagnosing acute appendicitis and also h
