Aim: The aim of this study was to compare the efficacy of modified electric vacuum aspiration (mEVA) and sharp curettage (SC) for treatment of incomplete abortion. Material and Methods: A randomized controlled trial was conducted between 1 March 2005 and 15 December 2009. Ninety-four women with incomplete abortion were randomly allocated into two groups, group A (n = 47) underwent mEVA and group B (n = 47) underwent SC. The procedures were performed using the paracervical block with 20 mL of lidocaine. Successful management and complication were assessed. Successful management was defined as complete uterine evacuation with no need for the second surgical procedure. Results: There were differences in women characteristics between groups. The successful rate of management was 100% for both groups. However, the operative time and estimated blood loss were less in the mEVA group than in the SC group. Severe pain was significantly less prevalent in group A than group B. Suspected endometritis was found in two (4.3%) patients in each group. Conclusions: The efficacy of mEVA was the same as that of SC in successful management of incomplete abortion, but pain was experienced more often in the SC group. © 2012 2012 Japan Society of Obstetrics and Gynecology.
