Abstract
BackgroundRoutine examinations have a low specificity and a low positive rate for the diagnosis of peritoneal lesions. This study aimed to evaluate the diagnostic value and safety of ultrasound-guided percutaneous peritoneal lesion biopsies in patients with ascites and/or abdominal distension with unclear causes.MethodsA retrospective analysis was performed in 153 consecutive patients with ascites and/or abdominal distension with unclear causes. All of the patients showed abnormalities of the peritoneum or greater omentum after ultrasonography, and underwent ultrasound-guided percutaneous biopsies using a Bard auto-biopsy gun with 18- or 16-gauge biopsy needles.ResultsThe success rate of the procedures was 100% (153/153) and the satisfaction rate of the tissue specimens in the biopsy was 91.5% (140/153). A specific histopathological diagnosis was made in 142 out of 153 patients, with an overall diagnostic accuracy of 92.8%. Among the diagnosed patients, 62 were peritoneal metastatic adenocarcinoma, 49 were peritoneal tuberculosis, 11 were peritoneal malignant mesothelioma, 8 were chronic peritoneal infections, 7 were pseudomyxoma peritonei, and 5 were primary peritoneal lymphoma. Only 11 patients did not get a pathologic diagnosis due to the lack of sufficient tissue specimen. No serious complications occurred.ConclusionsUltrasound-guided percutaneous biopsy could be a simple, safe and accurate diagnostic method in patients with ascites and/or abdominal distension with unclear causes.
Highlights
Routine examinations have a low specificity and a low positive rate for the diagnosis of peritoneal lesions
In northwest China, peritoneal tuberculosis is a common disease, yet it remains a big challenge for doctors to make an accurate diagnosis
The purpose of our study is to evaluate the clinical diagnostic value and safety of ultrasound-guided percutaneous biopsies for peritoneal lesions to further analyze the etiology of these lesions
Summary
Routine examinations have a low specificity and a low positive rate for the diagnosis of peritoneal lesions. This study aimed to evaluate the diagnostic value and safety of ultrasound-guided percutaneous peritoneal lesion biopsies in patients with ascites and/or abdominal distension with unclear causes. An ultrasound-guided percutaneous biopsy is already a common method for the histodiagnosis of abdominal lesions, such as those in the liver, kidney, pancreas and other solid organs [6,7,8], but so far, it is not often used for peritoneal and omental lesions [9,10,11]. The purpose of our study is to evaluate the clinical diagnostic value and safety of ultrasound-guided percutaneous biopsies for peritoneal lesions to further analyze the etiology of these lesions
