Objective To investigate the clinical value of transvaginal enucleation of benign ovarian cysts.Methods Transvaginal enucleation of benign ovarian cysts was carried out in 195 patients with surgical indications between January 2000 and June 2004.Relative surgical parameters were observed and recorded.Results Transvaginal operations were successfully completed in 190 patients,while conversions to open surgery were required in 5 because of massive pelvic adhesion.The operating time was 45~83 min(mean,50 min),the intraoperative blood loss was 30~90 ml(mean,45 ml),the time to first passing flatus was 4~24 hours(mean,8.5 hours),and the rate of postoperative pyrexia,18.4%(35/190).Follow-up for 2 weeks showed that patients resumed daily activities and regular works in a percentage of 72.1%(132/183) and 48.1%(88/183),respectively.Conclusions Transvaginal enucleation of benign ovarian cysts has been shown to be a safe and mini-invasive procedure that improves the(patient's) quality of life.

Objective To study the quantitative cytomorphologic parameters in early diagnosis and follow-up of lung cancer.Method With HE staining and image analysis,quantitative analysis of cytomorphology was made on paraffin sections of 86 specimens of bronchial mucosa,sampled by bronchoscopic biopsy,which would reflect a series of events from squamous metaplastic bronchial epithelium to invasive bronchogenic carcinoma.Result 8 nuclear parameters (area,deviation of area,perimeter,deviation of perimeter,shape factor,deviation of shape factor,volume density nucleus,nucleus/plasma ratio)and 2 cellular nodes(perimeter,deviation of perimeter)increased or decreased parallelly with advancing nuclear atypia.Conclusion The two stages of the moderate and severe atypical metaplasia of bronchial epithelium are the critical ones changing from benign to malignant.The quantitative analysis of cytomorphology is useful for discovering and following up the precancerous lesions of bronchogenic squamous cell carcinoma.
