Abstract:

Objective To investigate the incidence,characteristics,histopathologic category and treatment of parovarian cyst.Methods Retrospective analyses of 191 cases who treated with laparoscopic operation for parovarian cyst were analysed retrospectively.Results 1) The incidence of parovarian cyst was 20.9% in all adnexal cysts.175 cases(91.62%) were pure cysts;15 cases(7.85%) were common epithelial ovarian tumors(13 cases were serous cystadenoma;1 case was focal or junctional serous papillary cystadenoma;1 case was cystadenoma genesis from mesonephric duct which was moderate-severe atypical hyperplasia);1 case(0.53%) was high-differentiated papillary mesothelioma.2) 6 cases had the complication of ovarian torsion,4 in right side and 2 in left side.The diameter of torsional cyst ranged from 6¹2.67 cm,the average diameter was((8.66±)2.73)cm.The angle of torsion was 360°～720°.3) The most of cases were in reproductive age and have no obvious clinical manifestation.The levels of CA₁₂₅ in most of cases were normal.Conclusion Parovarian cyst was not an absolute nonmalignant disease and can be developed into malignant disease.The most of malignant parovarian cyst are serosity,which belong to low potential malignancy.The low malignant potential lesions should be treated as ovarian counterparts by laparotomy operation.
