Accuracy of the Double Contrast Enema in Evaluation of the Abdominal Diffusion of Ovarian Carcinoma

Abstract

The results of 103 double contrast enemas in 72 patients with ovarian carcinoma (stage III and IV) were compared with laparoscopic and/or laparotomic findings at comparable times. The evaluation of the validity of radiology in detecting the presence of abdominal disease showed an 84 % overall accuracy, 75 % specifity and 86 % sensitivity. The accuracy in detecting signs of adhesion and parietal infiltration of the large bowel was 76.3 %, due to the limited size of most of the lesions. Forty-seven of the 72 patients underwent a double contrast enema and laparoscopy during presurgical staging: accuracy in detecting lesions was the same for both examinations (80.4 %). When double contrast enema and laparoscopy were used together in the evaluation of abdominal extension of the disease, the diagnostic accuracy rose to 93.6 %.
