pubmed-article:8314132pubmed:abstractTextForty-five ovarian cancer patients were submitted to abdominopelvic computed tomography after intraperitoneal administration of soluble contrast in large fluid volumes (3 liters of normal saline) (IPC-CT), for a total of 66 exams. In all cases standard abdominopelvic CT scanning had previously missed the presence of disease. Peritoneal access was achieved by a temporary Teflon catheter inserted blindly. No major complications related to peritoneal access or fluid administration occurred. Laparotomy was performed in all cases to evaluate accuracy of this new diagnostic procedure. Overall, 32/66 exams showed no abnormal findings. In 9/32 cases persistence of disease was demonstrated by laparotomy. The remaining 34 exams were suggestive of persistence of tumor. In 19 cases CT scan showed nodular images or peritoneal thickness. Persistence of disease was confirmed by laparotomy in all instances. In 15 cases only an abnormal diffusion of soluble contrast into peritoneum (suprahepatic, anterior, or parietocolic region) was demonstrated. In 11/15 persistence of tumor was found at laparotomy. To summarize, IPC-CT revealed persistence of tumor in 30/39 cases (77% sensitivity). Positive results were predictive of persistence of disease in 30/34 cases (88% specificity). This new procedure was able to detect persistence of disease in most of our patients showing negative standard CT (30/39 vs 0/39; P < 10E-8) and its diagnostic accuracy was even better than standard CT+serum tumor markers (30/39 vs 16/39; P < 0.001). In conclusion, IPC-CT could be very effective in monitoring response to treatment and could markedly reduce the number of ovarian cancer patients requiring second-look laparotomy.lld:pubmed
