术中超声在畸胎瘤手术时对侧卵巢探查中的价值探讨

目的探讨术中超声在单侧卵巢畸胎瘤手术中评价对侧卵巢的价值。方法对41例（平均年龄30岁）术前经影像学检查提示一例卵巢畸胎瘤的患者，术中行对侧卵巢超声检查，超声医师与手术医师共同对图像进行观察和分析。结果生育期正常卵巢内见卵泡，卵泡间组织呈均匀中高回声：血体形成时无回声内见点状回声，黄体形成时呈中高回声、低回声或呈网隔状结构出现高回声团高度怀疑小型畸胎瘤。本组资料38例患者对侧卵巢未显示明显畸胎瘤声像图改变，其中2例经术中剖视证实，36例未行术中剖视，2例显示液性为主混合回声区者剖视证实为黄体。结论术中超声探头频率高，探测卵巢不受位置及周围脏器的影响，可弥补术前超声的不足，进一步确定有无小病灶，从而指导手术进行剖视，减少不必要的手术创伤。

Application of intraoperative ultrasonography in the evaluation of contralateral ovary in unilateral ovarian cystic teratoma surgery

Objective To investigation the value of intraoperative ultrasonography in the evaluation of contralateral ovary in unilateral ovarian cystic teratoma surgery. Method Fourty-one patients （mean age 30 years old） with diagnosed unilateral ovarian teratoma by preoperative sonography examination, received intraoperative ultrasonography of contralateral ovarian. The images were observed and assessed by both ultrasonographic doctors and surgeons. Result Follicles could be seen in normal ovaries in reproductive age. Tissues among follicles showed uniformly moderate to high echogenicity when corpus hemorrhagicum fomled. It was echoless or spotty. It showed moderate to high or low echogenicity with septa when corpus luteum formed. It was highly suspected small teratoma when hyperechogenic mass was detected. This group＇ s data showed that there is no obvious ovarian teratoma in contralateral ovarian on intraoperative ultrasonography. Two cases were confirmed by cutting open during surgery. Two cases showed mainly fluid-oriented area with mixed echogenicity were confirmed as corpus luteum By operation. Conclusion lntraoperative ultrasonography with high-frequency transducer detects overies not being influenced by its location and surrounding organs. Therefore, intraoperative ultrasonography can overcome deficiencies of preoperative ultrasonography and further detect small lesions to avoid other operative injury.
