Ultrasound Guided Biopsy (Targeted biopsy): A Useful Method of Extraction of Sample Tissues to Examine the Diagnostic Accuracy of Malignant and Benign Lesions

Abstract

Background: Biopsies the extraction of sample tissues for examination to determine the presence or extent of a disease. Tissue is sent to laboratory for examination by a pathologist. Laboratory reports based on biopsy is the most reliable investigation for clinicians. However extraction without any guidance is not accurate as compared to under US guidance. This procedure is performed by an interventional radiologist. Ultrasound guidance is currently considered the most cost-effective and safe way to perform biopsies. Aim: To evaluate diagnostic accuracy of ultrasound guided biopsy, confirmed on 78 cases from different organs Methods: This descriptive study comprised 78 patients referred for biopsy to the Radiology Department Kuwait Teaching Hospital, Peshawar Medical College from April 2017 to September 2017. The cases were sent from almost all the teaching hospitals of Peshawar, Hayatabad Medical Compelx, Lady Reading Hospital, Kuwait Teaching Hospital and Mardan Medical Complex Mardan. Patients were selected for biopsy from different specialties including general surgery, general medicine gastroenterology, gynecology, ENT and pediatric. Biopsy was indicated after evaluation of the pts with different modalities like CT, MRI, USG and some clinically suspected. Results: Patients were between 14 to 85 years of age. Most of the patients were of liver diseases having ages of 30-61 years. This study proves that the accuracy of biopsy from the lesion was 100%. Out of these 78 cases liver 52.56%, lymph node 17.95%, gall bladder 7.70%, pleura 5.13%, lungs 3.85%, kidneys 3.85%, adnexa 2.56%, uterus 1.28%, pancreas 1.28%, spleen 1.28%, adrenal 1.28%, and breast 1.28%. The laboratory findings of these 78 biopsies confirmed that primary tumor were 52(66.66%), metastasis 15(19.23%), acute or chronic 6 cases (7.70%) and 5(6.41%) were miscellaneous. Conclusion: Almost all the fields have the confidence of referring cases for USG guided biopsy and the accuracy of biopsy from the lesion was 100%.
