Successful laparotomy tumor resection and levonorgestrel-releasing intrauterine system for atypical polypoid...

Hysteroscopic transcervical resection (TCR) is often performed as fertility sparing treatment for atypical polypoid adenomyoma (APA) patients. However, TCR has the risk of uterine wall perforation, especially when the tumor extends deeply into the uterine muscle layer. We report an APA patient in whom it was impossible to completely resect the tumor by TCR, but laparotomy tumor resection followed by levonorgestrel-releasing intrauterine system (LNG-IUS) was successful. The patient was a 35-year-old nulligravida woman. We performed laparotomy tumor resection and inserted the LNG-IUS into uterine cavity just after surgery. Microscopic residual tumor was suspected based on histopathological findings. However, the patient has not relapsed for 26 months, even though the LNG-IUS was removed after 6 months. Laparotomy tumor resection may be one fertility sparing treatment option for APA patients. Furthermore, it may be effective to use the LNG-IUS after surgery for two purposes that are adhesion prevention and tumor disappearance.
