Efficacy of diagnostic methods of the hollow organ defect at postoperative peritonitis for cancer patients
Objectives. To compare the efficacy of the main techniques of express-diagnostics of the hollow organ defect in cancer patients when the postoperative peritonitis is suspected. Methods. Comparison of the indexes of diagnostic efficacy of clinical technique, X-ray contrast, colour contrast and X-ray colour contrast investigations to reveal the hollow organ defect in 130 cancer patients with the postoperative peritonitis was performed. The percentage of truly positive results as well as sensitivity, specificity and accuracy of the applied technique were calculated. Results. Sensitivity of X-ray contrast imaging was inferior to clinical examination (p0,05). Specificity of contrast techniques was maximal (100,0%), and the clinical examination didnt exclude cases of hyperdiagnostics (60,0%, p>0,05). Diagnostic precision of all the techniques did not differ (p>0,05) and ranged from 67,4% to 92,3%. Conclusions. Definite character of the separated liquid from drainages had high diagnostic sensitivity. X-ray contrast imaging was a conclusive method of perforation revealing in the absence of the drainage function of the abdominal cavity.
