Abstract Background: To investigate the clinical value of CT-guided percutaneous fine-needle aspiration biopsy for peritoneal lesions of unknown nature. Methods: A retrospective analysis was conducted of 84 patients with peritoneal thickening for unknown reasons. There were 26 males and 58 females who underwent CT-guided percutaneous fine-needle aspiration biopsy for peritoneal lesions. Result: Among these 84 patients, no definite pathologic diagnosis was made in 3 patients, who were lost to the follow-up. The accuracy rate of CT-guided percutaneous fine-needle aspiration biopsy was 95.1% (77/81). Sixty lesions were pathologically-diagnosed with malignancies (74.1%), including 55 with peritoneal metastases, 4 with malignant mesotheliomas, and 1 with a lymphoma. Twenty-four patients (33.8%) were diagnosed as benign lesions, including 11 with tuberculosis and 13 with inflammatory lesions. The complications of CT-guided percutaneous fine-needle aspiration biopsy included bleeding in 1 patient and ascites leakage in 2 patients. Conclusion: CT-guided percutaneous fine-needle aspiration biopsy is a safe and effective method for diagnosing peritoneal lesions. Keywords: Peritoneal, Computed tomography
Background Peritoneal lesions have a variety of causes and the radiologic manifestations are complex and diverse. Routine clinical examination and radiologic examinations are of limited value for identifying the etiology and for differential diagnosis of malignant and benign lesions. Ultrasound-guided percutaneous fine-needle aspiration biopsy and laparoscopy is the conventional method to acquire peritoneal specimens for histopathologic evaluation;
however, this procedure is more suitable for sampling of superficial peritoneal lesions and laparoscopy entails a high risk and cost. CT-guided percutaneous fine-needle aspiration biopsy has proven to be a mature and widely used technology [1], especially for lesions in the liver and pancreas. To date, few reports address CT-guided percutaneous fine-needle aspiration biopsy of the peritoneum. We conducted a retrospective analysis of 84 patients who underwent this procedure at our hospital in the past 4 years. The purpose of the study was to discuss the diagnostic value of this method for peritoneal lesions.
