BackgroundThere appears to be a rise in the rate of emergency peripartum hysterectomy (EPH) in the developed world.Aims  To determine the incidence, indications, risk factors, complications and management of EPH in our tertiary level teaching hospital, the Royal Hospital for Women (RHW) in Sydney, over the last decade.MethodsA retrospective analysis was conducted of all cases of EPH performed at the RHW between the years 1999-2008 inclusive. EPH was defined as one performed after 20 weeks gestation for uncontrollable uterine bleeding not responsive to conservative measures occurring at any time after delivery but within the first 6 weeks post-partum. Cases were ascertained via our hospital obstetric database.ResultsThere were 33 EPH among 38,998 births, a rate of 0.85 per 1000 births. Indications for EPH were morbid adherence of the placenta (54.8%), placenta praevia (19.4%), uterine atony (12.9%) and uterine rupture or cervical laceration (9.7%). A significant association between previous caesarean section (CS) and abnormal placentation was confirmed (P=0.011), especially for morbid adherence of the placenta (P=0.004). There was one maternal death. Maternal morbidity was significant, with disseminated intravascular coagulation and urinary tract injury among the most common complications. All women required blood transfusions, and over a quarter were admitted to the intensive care unit.ConclusionsIn our series, abnormal placentation causing severe haemorrhage was the commonest indication for EPH. Previous CS is a risk factor for abnormal placentation and particularly for morbid adherence of the placenta. The morbidity associated with EPH is considerable.© 2011 The Authors.
