Ovarian remnant syndrome (ORS) is a rare, but well-known gynecological complication, most often induced by difficult bilateral salpingo-oophorectomy (BSO) procedures that leave residual ovarian tissue on the pelvic wall. The most common preexisting conditions for this complication include endometriosis, pelvic inflammatory disease and prior abdominal surgery. The residual ovarian tissue may eventually cause malignant development. A total of 12 cases of malignant and benign tumors (clear cell adenocarcinoma in 1 case, mucinous-type tumors in 2, endometrioid-type tumors in 5, adenocarcinoma in 3 and border serous neoplasia in 1) and 21 benign cysts developing from an ovarian remnant have been described in the literature to date. Endometriosis, known to increase the risk of ovarian cancer, predisposes patients to ORS, with an incidence rate of 30 to 50% in ORS patients with ovarian carcinoma. Although the true incidence of ORS remains unknown, when endometriotic adhesions are diagnosed during BSO, the possibility of ORS and subsequent ovarian malignant transformation may mandate complete surgical resection.
卵巢残留综合征（ORS）是一种罕见但广为人知的妇科并发症，最常由困难的双侧输卵管卵巢切除术（BSO）引起，该手术会在盆腔壁上留下残留的卵巢组织。这种并发症最常见的既往疾病包括子宫内膜异位症、盆腔炎和既往腹部手术史。残留的卵巢组织最终可能导致恶变。迄今为止，文献中已报道了12例恶性和良性肿瘤（1例透明细胞腺癌、2例黏液型肿瘤、5例子宫内膜样型肿瘤、3例腺癌和1例交界性浆液性肿瘤）以及21例由卵巢残留发展而来的良性囊肿。已知子宫内膜异位症会增加卵巢癌风险，使患者易患ORS，在患有卵巢癌的ORS患者中发病率为30%至50%。尽管ORS的真实发病率尚不清楚，但当在BSO过程中诊断出子宫内膜异位粘连时，ORS及随后卵巢恶变的可能性可能要求进行彻底的手术切除。
