Abstract

Purpose: During the last decade, electromechanical power morcellation (EMM) was more frequently used but it may be associated with the dissemination of occult malignancies. The aim of the present study was to determine the frequency of unexpected uterine malignancies after EMM. Methods: This retrospective study consisted of patients who were treated at three departments of Gynecology in Germany from 2008 to 2017. We identified women who underwent an operation with the use of EMM. Clinical records, risk factors, and the outcomes of the patients were reviewed. Results: We performed an analysis of 1683 patients who had undergone laparoscopic supracervical hysterectomy (LASH), total hysterectomy, or myomectomy (LM) (48.6%, 8.4%, and 43.0%, respectively). Unexpected malignancies were detected in 4 of 1683 patients (0.24%). In all cases, the malignancy proved to be a sarcoma and was detected after LASH. All patients with occult sarcomas were older than 45 years and the most common (75%) risk factor was the appearance of a solitary tumor. The patients underwent secondary laparotomy for complete oncological staging, and no histological dissemination of the sarcoma was registered. Two patients had a recurrence. At the final follow-up investigation all four patients were in good general health. Conclusion: Occult malignancies are liable to spread after EMM, although the overall risk of being diagnosed with an occult malignancy and the risk of dissemination appear to be low. Once the preoperative diagnostic investigation has yielded no suspicious findings, laparoscopic morcellation may be considered a safe method, especially LM in patients of reproductive age.
