Clinical value of CT-guided percutaneous biopsy of peritoneum in diagnosis of patients with unknown ascites / 局解手术学杂志

ABSTRACT

Objective To investigate the diagnostic value of CT-guided percutaneous biopsy of peritoneum for unknown ascites.Methods The clinical data of 106 cases of unknown peritoneum in our hospital were collected retrospectively over the past five years (May 23,2011 to August 2,2016).The sensitivity and specificity of the percutaneous biopsy of peritoneum in diagnosis of the patients with unknown etiological ascites were evaluated.Complications were collected to evaluate the safety.Results The 106 patients with unknown ascites were performed with CT-guided percutaneous biopsy of peritoneum.The diagnoses of 91 patients were confirmed pathologically,accounted for 85.85％ of the total.Among the 91 patients,there were 60 cases (56.60％) of malignant and 31 cases (29.25％) of benign.The other 15 patients had no clinical diagnosis,which accounted for 14.15％ of the total.The diagnostic sensitivity and specificity was 88.35％ and 100％ respectively,which were significantly superior to cytological examination,biochemical markers and other routine analysis.No severe complications were observed in all patients.Conclusion CT-guided percutaneous biopsy of peritoneum for unknown ascites plays an important instructive role in diagnosis with high accuracy,and it is a safe and effective method.
