ABSTRACT
OBJECTIVE: We investigated the clinical value of using preoperative differential white blood cell (WBC) count to predict the potential for malignancy of adnexal masses in laparoscopic surgery. METHODS: The electronic medical records of 1325 patients who underwent laparoscopic surgery for adnexal masses between July 2005 and December 2008 were analyzed retrospectively. RESULTS: Of 1325 patients, 30 (2.3%) had adnexal masses with malignant potential. Analysis of differential WBC count, neutrophil to lymphocyte ratio (NLR), neutrophil to monocyte ratio (NMR), serum CA 125, mass size showed that only cyst size was significantly different between patients with potentially malignant adnexal masses, those with benign disease (averages of 9.45 cm vs. 6.23 cm, p=0.001). Further analysis was performed using a combination of various markers and multiplication of cyst size and NMR yielded the highest area under the curve, at 0.711(95% confidential interval 0.619~0.806, p<0.001), with a sensitivity and specificity of 86.7% and 48.3% respectively, at a cut off value of 67.23. These values were also significantly different between patients with potentially malignant adnexal masses, and dermoid cyst or endometrioma (p=0.038 and 0.002 respectively, by analysis of variance, post hoc test). CONCLUSION: Preoperative measurement of NMR in conjunction with cyst size may be used as a simple, non invasive marker for predicting the malignant potential of adnexal masses before laparoscopic surgery.

OBJECTIVE: This study was designed to analyze outcome of removal of non-palpable Implanon(TM) by ultrasound guidance. METHODS: This is retrospective study of patients who were referred from local clinic where removal of non-palpable Implanon(TM) had been failed. The cases were 32 patients who visited to Yonsei University Gangnam Severance Hospital between March 2004 through March 2009. RESULTS: Implanons(TM) were localized on ultrasound in all 32 cases. 18 cases were located in subcutaneous layer, 10 cased were located in fascial layer, 4 cases were located in muscle layer. All cases were successfully removed. The average length of time required for removal was 19.3 minutes. There was no complication except one patient, who had mild median nerve injury. CONCLUSION: Ultrasound guidance removal was safe and effective procedure to remove non palpable Implanon(TM).
