Objective: We wanted to assess the diagnostic value of computed tomographic colonography (CTC) in recognizing bowel endometriosis in comparison with serum Ca125, transvaginal sonography (TVS), and presence of intestinal symptoms. Methods: We included in this study 92 women undergoing surgery for symptomatic DiE. Preoperative evaluation included clinical history, Ca125 serum value, and TVS. CTC was performed in 37/92 patients (40.2%), and the results were compared to the other preoperative tools and to surgical exploration, considered the clinical reference standard. Results: Surgery confirmed bowel endometriosis in 49/92 subjects (53.3%). Presence of intestinal symptoms, serum Ca125 values, and TVS were significantly correlated to intestinal involvement, but CTC had the highest accuracy in detecting bowel endometriosis with a sensitivity of 68%, a specificity of 67%, a PPVof 81%, and a NPVof 50%(P = 0.04). Conclusions: CTC proved to be an accurate and low invasive imaging technique to detect DiE of the bowel and compared favorably with clinical evaluation, serum Ca125 determination, and TVS.

Abstract

Objective: We wanted to assess the diagnostic value of computed tomographic colonography (CTC) in recognizing bowel endometriosis in comparison with serum Ca125, transvaginal sonography (TVS), and presence of intestinal symptoms. Methods: We included in this study 92 women undergoing surgery for symptomatic DiE. Preoperative evaluation included clinical history, Ca125 serum value, and TVS. CTC was performed in 37/92 patients (40.2%), and the results were compared to the other preoperative tools and to surgical exploration, considered the clinical reference standard. Results: Surgery confirmed bowel endometriosis in 49/92 subjects (53.3%). Presence of intestinal symptoms, serum Ca125 values, and TVS were significantly correlated to intestinal involvement, but CTC had the highest accuracy in detecting bowel endometriosis with a sensitivity of 68%, a specificity of 67%, a PPVof 81%, and a NPVof 50%(P = 0.04). Conclusions: CTC proved to be an accurate and low invasive imaging technique to detect DiE of the bowel and compared favorably with clinical evaluation, serum Ca125 determination, and TVS.
