Diagnostic Yield and Safety of Ultrasound Guided Percutaneous Omental biopsy. A Single Centre Experience.
Main Article Content
Abstract
Objectives: This study aims to evaluate the diagnostic yield of ultrasound-guided omental biopsy and its complications.
Methodology: This cross-sectional descriptive study was conducted in the Interventional Radiology Department of Rehman Medical Institute, Peshawar, Kpk. Data from February 2019 to December 2022 was retrospectively analyzed and interpreted in terms of diagnostic and inconclusive results, re-biopsies, and associated complications.
Results: A total of 29 ultrasound-guided omental cake and nodule biopsies were performed, and the diagnostic yield was 93%, with only 3% requiring a re-biopsy. The biopsies comprised metastatic ovarian carcinoma (25.9%), malignant mesothelioma (11.1%), tuberculosis (11.1%), metastatic carcinoma of an unknown primary (40.7%), Burkitt lymphoma (3.7%) and tuberculous and mesothelial features (3.7%). Ascites was present in 28 patients, with no major complications observed. Minor bleeding occurred in 25 cases, but all patients remained hemodynamically stable.
Conclusion: Ultrasound guided percutaneous omental biopsy is a safe and effective procedure for diagnosing both neoplastic and non-neoplastic pathologies involving the omentum.
