RESUMO
Objective To analyze the clinical characteristics and misdiagnosis of pelvic abscesses.Methods Retrospective study of 69 patients operated in our hospital was performed to evaluate the clinical characteristics and misdiagnosis of the pelvic abscesses.Results The clinical characteristics of pelvic abscesses were not specific,and the main symptoms and signs were repeated lower-abdominal pain,fever,chill and pelvic masses.The serum CA125 level elevated(greater than 35U/ml) in 78%.The ultrasonographic findings of pelvic abscesses were not specific.The accurate rate of ultrasonographic diagnosis was 30%.The accurate rate of preoperative diagnosis was 42%.Conclusion The misdiagnosis of pelvic abscesses was high.The clinical parameters combined with serum CA125 and US investigation can improve the accurate diagnosis rate.
RESUMO
Determinations of the serum Ca-125 levels were carried out on 45 samples from healthy women, 22 samples of benign ovarian tumors including tumor-like conditions, 33 samples of ovarian cancer and 14 cases of common epithelial cancer at second-look laparotomy. The Ca-125 levels were measured by enzyme immunoassay using a commercial kit by Fujirebio Inc. Japan. The cut off levels of Ca-125 values were set at > 30 IU/ml, which made the specificity, sensitivity and positive predictive values 80.0, 84.8 and 75.7 percent respectively. The demonstrable ovarian cancer gave positive Ca-125 values among serous cystadenocarcinoma in all case while endometrioid adenocarcinoma and mucinous cystadenocarcinoma were 80.0 and 66.6 percent respectively. Two sex cord tumors and 2 of 3 malignant germ cell tumors had positive Ca-125 values in low levels. Those with small residual cancer at second-look laparotomy, 1-2 cm in diameter, had positive Ca-125 values, and one of 12 patients had false-negative value despite the presence of microresidual cancer. Ovarian endometriosis had positive Ca-125 values about 55.5 percent but in low levels.
