Ovarian remnant syndrome (ORS), a rare condition in which remnant ovarian tissue presents as a pelvic mass and/or pain after previous oophorectomy, poses a diagnostic and treatment challenge. This study reviews the recent studies in the past 5 years on the subject.
Incomplete removal of ovarian tissue at the time of initial oophorectomy from inability to obtain adequate surgical margins or inappropriate extraction from the pelvic cavity during laparoscopy can cause ORS. Excision of ovarian remnant tissue is increasingly approached minimally invasively. Cases of malignant involvement of the remnant ovary have been reported. Endometriosis, recently suggested to increase the risk for ovarian cancer, predisposes to ORS and is associated with 50% of patients with ovarian carcinoma in ORS patients.
Surgical excision remains the treatment of choice in ORS as malignancy can be associated with the remnant tissue. In cases of endometriosis, complete excision of endometriosis and ovarian tissue at the time of initial surgery prevents recurrence of endometriosis, subsequent development of ORS and possible ovarian malignant transformation.
卵巢残馀症候群（ORS）是一种罕见病症，指先前卵巢切除术后残留卵巢组织在盆腔形成肿块和/或疼痛。本研究对过去 5 年来该主题的最新研究进行综述。
初次卵巢切除术中由于无法获得足够的手术切缘或腹腔镜下从盆腔取出不当，导致卵巢组织残留不全，可引起 ORS。切除卵巢残馀组织的方法越来越微创。有报道称残余卵巢有恶性浸润。内异症最近被认为增加卵巢癌的风险，易导致 ORS，并与 ORS 患者中 50%的卵巢癌患者相关。
由于残余组织可能与恶性肿瘤相关，因此手术切除仍然是 ORS 的治疗选择。对于内异症患者，初次手术时彻底切除内异症和卵巢组织可预防内异症复发、随后发生 ORS 和可能的卵巢恶性转化。
