腹腔鏡手術により卵巣温存できた胎児共存部分胞状奇胎娩出後の黄体化過剰反応（Hyperreactio Luteinalis）の１症例

抄録

　Hyperreactio luteinalis (HL) characterized by multicystic bilateral ovarian enlargement, increased serum β-human-derived chorionic gonadotrophic hormone levels, and spontaneous regression after delivery is a rare benign condition that complicates pregnancy.

　We present a case of conservative laparoscopic surgery performed for management of HL after miscarriage of a partial hydatidiform mole coexistent with a fetus.

　A 30-year-old woman presented after miscarriage of a partial hydatidiform mole coexistent with a fetus and was diagnosed with HL. She received conservative treatment, per our hospital policy; however, owing to persistent pain, we performed laparoscopy, which revealed torsion of the right adnexa around the ovarian ligament. We released the torsion and punctured the multicystic bilaterally enlarged ovaries.

　Effective obstetric training is important for accurate and early diagnosis to enable prompt management of associated complications and may prevent unnecessary oophorectomies. Laparoscopic surgery is useful for prompt management of symptoms and preservation of ovarian function.
