Per operative and histopathological diagnosis in abdominal conditions
Journal Title: Medpulse International Journal of Surgery - Year 2017, Vol 4, Issue 3
Abstract
Background: Ultrasound has got a sensitivity of 80 to 85 % for diagnosing pyogenic liver Abscess. The following features lead to the diagnosis- Double target sign-seen as wall enhancement with surrounding Hypo dense zone due to edema.30% cases contain gas within the lesion Shows as a solid spherical lesion with an ill-defined margin and low reflectivity Methodology: After the initial evaluation at the emergency department for acute cases and in the wards for stable patients with chronic abdominal conditions, clinical diagnosis was done by various clinical methods. The clinically diagnosed acute and chronic abdominal cases were subjected to ultrasound examination. Informed consent was taken prior to the examination. Results: the Sensitivity i.e. the ability to correctly diagnose is 84.1%, the Positive Predictive value i.e. the ability of ultrasound in diagnosing Acute Abdomen is right 92.5% of the time. Whereas the Specificity i.e. the ability of ultrasound to rule out the diagnosis of acute abdomen is only 50%, and the Negative Predictive value i.e. the ability of USG in ruling out Acute Abdomen in only 30% of the cases. Conclusion: From our study it could be concluded that, in acute abdominal conditions, ultrasound is a more sensitive investigation and is non invasive.
