We present a case with nonvisible strings of her levonorgestrel intrauterine system (LNG-IUS) in the cervix. The LNG-IUS was subsequently found in the omentum and retrieved laparoscopically. An algorithm for missing strings of an intrauterine devised is proposed.
我们报告了一例宫颈内左炔诺孕酮宫内节育系统（LNG-IUS）的不可见缝线病例。随后在大网膜中发现了 LNG-IUS，并通过腹腔镜取出。提出了一种用于诊断宫内节育器缝线丢失的算法。
