Computed tomography prior to surgery for ovarian carcinoma.

The value of investigation of patients with ovarian carcinoma by preoperative computed tomography scan was evaluated in all the patients operated on during the last 2 years; 22 patients were included in this study and evaluated. In 11 patients the scan was performed prior to the primary surgery and in the other 11 patients before second look following chemotherapy. CT scan was found to be highly sensitive in detecting ascites, pelvic wall extension and spread or involvement of the uterus. Peritoneal and omental spread was detected in only half of the patients before primary surgery. Prior to second look operation CT scan was effective in excluding liver metastasis, ascites, paraaortic lymph node enlargement, pelvic wall extension and pelvic residual tumour. Generally, CT scan failed to detect peritoneal and omental spread. It is an important tool for preoperative evaluation of the extension of the disease and planning of surgery, but still, the final staging deserves explorative laparotomy.
