METHODS： A retrospective analysis of data was per- formed on consecutive patients who underwent perito- neoscopic and abdominal computed tomography （CT） evaluations. Among 75 patients at the Seoul National University Hospital from January 2000 to June 2010 who underwent both tests, 27 patients （36.0%） and 25 patients （33.3%） were diagnosed with TBP and PC, re- spectively. Diagnosis was confirmed by peritoneoscopic biopsy. RESULTS： Serum c-reactive protein （7.88：1：6.62 mg/ dL vs 3.12 ＋ 2.69 mg/dL, P = 0.01）, ascites adenos- ine deaminase （66.76：1：32.09 IU/L vs 13.89 ：l： 8.95 IU/L, P 〈 0.01）, ascites lymphocyte proportion （67.77 ：1： 23.41% vs 48.36 ＋ 18.78%, P 〈 0.01）, and serum- ascites albumin gradient （0.72 ＋ 0.49 g/dL vs 1.05 ＋ 0.50 g/dL, P = 0.03） were significantly different be- tween the two groups. Among tumor markers, serum and ascites carcinoembryonic antigen, serum carbohy- drate antigen 19-9 showed significant difference be- tween two groups. Abdominal CT examinations showed that smooth involvement of the parietal peritoneum was more common in the TBP group （77.8% vs 40.7%） whereas nodular involvement was more common in the PC group （14.8% vs 40.7%, P = 0.04）. From receiver operating characteristic （ROC） curves ascites adeno- sines deaminase （ADA） showed better discriminative capability than tumor markers. An ADA cut-off level of 21 IU/L was found to yield the best results of differ- ential diagnosis; sensitivity, specificity, positive predic- tive value, and negative predictive value were 92.0%, 85.0%, 88.5% and 89.5%, respectively. CONCLUSION： Besides clinical and radiologic findings, ascitic fluid ADA measurement is helpful in the differen- tial diagnosis of TBP and PC.展开更多

It is also a disease that prevents escaping poverty. There is a case report of disseminated tuberculosis with peritoneal involvement and peritoneal responsible for the clinical manifestations that may delay diagnosis. This location deserves mention as a share of expansion of tuberculosis in the presence of abdominal pain and bread signs of lung disease at a lower cost balance.展开更多
