Abstract:
The aim of this study was the echo-guided fine-needle aspiration puncture of abdominal lesions to be evaluated. 91 punctures of 85 patients with local lesions were performed. In 6 cases the puncture was repeated because of the lack of material for cytologic study just blood presence in the needle. In 47 cases with carcinoma or metastatic masses the puncture allowed aspiration of malignant cells. In 7 cases the puncture was therapeutic aspiration of pus collection and antibiotical application. The accuracy of this method was 92.9%, sensitivity 87.8% and specificity 96.1%. No significant complication to report occurred.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
