Abstract
Ante- or neonatal ovarian cysts can be often diagnosed by routine ultrasonography. Small simple ovarian cysts, which can be followed with serial ultrasonography, usually resolve spontaneously. Large simple cysts and complicated cysts should undergo surgical treatment to reduce the potential for serious complications. Seventeen ovarian cysts were experienced between 1983 and 1997. Sixteen cases underwent surgical treatment at less than 1 month of age according to our protocols. In this report, we reviewed these cases for clinical presentation, ultrasound data, management, intraoperative findings, complications, and outcome. At operation, nine of them showed torsion, and seven of them showed necrotic changes. Only five of them was considered to fall into torsion by preoperative ultrasonography. In five cases whose blood flow could not improve after reduction of torsion, salpingo-oophorectomy was performed. We consider that small simple ovarian cysts under 4 cm in diameter can be observed carefully with serial ultrasonography. But, not only complicated ovarian cysts and simple cysts over 5 cm in diameter, but smaller cysts showing no decrease in size should be considered for surgical indication to rescue the ovarian tissue.Keywords
