Comparison of Incomplete Abortion Treatment between Manual Vacuum Aspiration and Curettage

Miscarriage was estimated 20% of all pregnancy every year, approximately. There are different modalities, medical or surgical, to treat incomplete abortion. One of the procedures is manual vacuum aspiration (MVA). It is a new method in Iran. The aim of this study was to evaluate the efficacy of this method in Iran. This randomized clinical trial was designed to compare MVA against sharp curettage in incomplete abortion treatment. The two universities related medical centers with obstetric department were engaged. The 316 cases were elected by inclusion criteria and then allocated into MVA (156 cases) or curettage (160 cases) treatment group. They were followed up for three weeks and blood pressure, pain with visual analogue scale; patient satisfaction and bleeding were evaluated in every subject by gynecologist. At the end, data were analyzed using by SPSS15 software. Duration of surgery was significantly shorter in MVA than curettage group. Although there were no difference in pain score at admission but patients had less pain during surgery and one hour after surgery in MVA group. Patients in curettage group had more bleeding during surgery. Satisfaction score were significantly more in MVA group at discharge (96.2% against 83.3 %) but this difference was not significant between two groups, 1 and 3 weeks after surgery. Our findings showed that MVA was effective to treat incomplete abortion. It has less complication and bleeding. In addition, satisfaction is high and it consider cost effective.
