OBJECTIVES: Hysteroscopic morcellation (HM) is a technique for removing endometrial polyps using the rotational mechanical energy of the morcellator. The objective of this review is to pool the result of HM for removal of endometrial polyps in terms of the safety and effectiveness. METHODS: Two reviewers independently selected the articles using 8 Korean databases, MEDLINE, EMBASE, and Cochrane Library and collected data regarding the safety outcomes based on complication rate and fluid deficit, and for the effectiveness outcomes based on success rate, surgical usability (operating time, resection time, installation time, and the number of insertions of instrument), and pain. RESULTS: Out of 270 articles searched, a total of 9 articles including 5 comparative studies compared HM with hysteroscopic resection (HR) and 4 single arm studies were finally included in this review. The results of our meta-analysis indicated that complication rate was not significantly different in between the 2 groups (RR=0.67, 95% CI: 0.43~1.03, p=0.07, I=0.0%), whereas success rate was significantly higher in the HM group than in the HR group (RR=1.13, 95% CI: 1.02~1.26, p=0.02, I=60.0%). Fluid deficit was significanty less in HM group than in the HR group in 1 comparative study while the other study presented no significant difference in between two groups. Four comparative studies reported significantly better surgical usability and pain in the HM group compared to the HR group, or similar results in between the 2 groups without significant difference. CONCLUSIONS: On the basis of current data, HM is a safe and effective technique for removing endometrial polyps compared with HR since there was no significant difference in complications and fluid deficit between the two groups and besides better results on success rate, surgical usability, and pain in the HM group than in the HR group.
