Spontaneous abortion: short-term complications following either conservative or surgical management

Spontaneous abortion is a common gynaecological condition. It is a commonly held belief that medical morbidity associated with this condition is low and that routine treatment should be surgical evacuation of the uterus. This study was performed to study the short-term complications of spontaneous abortion and its management. Transvaginal sonography (TVS) was used to determine whether retained products of conception (POCs) were visible inside the uterus in women presenting with spontaneous abortion. If tissue was present, surgical evacuation of retained products of conception (ERPC) was performed. If the uterus was empty, the patients were managed expectantly. Four hundred and seventy women were treated with ERPC and 297 were managed expectantly. The complication rate was 3.0% in those managed expectantly compared with 5.8% for those treated by ERPC. Subjects with no POCs on TVS can therefore be managed expectantly without increasing the risk of morbidity associated with this condition.
