A 54-year-old woman is scheduled for laparotomy due to a pelvic mass. At the time of exploratory laparotomy, a unilateral ovarian neoplasm is discovered that is accompanied by a large omental metastasis. Frozen section diagnosis confirms metastatic serous cystadenocarcinoma.
Which of the following is the most appropriate intraoperative course of action?a. Excision of the omental metastasis and ovarian cystectomy
The survival of women who have ovarian carcinoma varies inversely with the amount of residual tumor left after the initial surgery. At the time of laparotomy, a maximum effort should be made to determine the sites of tumor spread and to excise all resectable tumor. Although the uterus and ovaries may appear grossly normal, there is a relatively high incidence of occult metastases to these organs; for this reason, they should be removed during the initial surgery. Ovarian cancer metastasizes outside the peritoneum via the pelvic or para-aortic lymphatics, and from there into the thorax and the remainder of the body. Therefore, a complete staging procedure also includes pelvic washings, pelvic and abdominal exploration for metastatic disease, appendectomy, and lymph node sampling.
