Abstract

Objective: To evaluate the imaging characteristics, histopathological outcomes, and safety of percutaneous ultrasound-guided pancreatic biopsy. Materials and Methods: This prospective descriptive study was conducted on 33 patients with pancreatic lesions who underwent ultrasound-guided percutaneous biopsy at a central hospital from January 2023 to June 2024. Clinical, imaging, histological data, and procedure-related complications were collected and analyzed. Results: The majority of patients were male (60.6%) with a mean age of 63.6 ± 11.2 years. Most pancreatic lesions were located in the head of the pancreas (51.5%), appeared hypoechoic (81.8%), and had irregular margins (75.8%). Adenocarcinoma accounted for 72.7% of histological diagnoses. The sensitivity, specificity, and overall diagnostic accuracy of the procedure were 92.3%, 100%, and 93.9%, respectively. Minor complications occurred in 6.1% of cases and required no specific treatment. Conclusion: Percutaneous ultrasound-guided pancreatic biopsy is a feasible and accurate method with an acceptable safety profile. It can be considered a practical alternative for tissue diagnosis in pancreatic lesions, especially in settings where endoscopic ultrasound is not readily available.
