AN AUDIT OF THE MANAGEMENT OF ECTOPIC PREGNANCY

Objective-To estimate the local incidence of ectopic pregnancy and to review the management of ectopic pregnancy with reference to those misdiagnosed at presentation. To establish management guidelines to be applied to all possible ectopic pregnancies. Design-A review of all ectopic pregnancies presenting over a 2-year period, and of emergency gynaecological admissions during 4 months. Setting-A teaching hospital Results-The local rate of ectopic pregnancy was similar to that seen in other UK studies. Nineteen (13%) women with ectopic pregnancies were sent home with an incorrect diagnosis. Eight were recalled but eight required emergency admission and one died at home. Undue confidence in ultrasound reports and failure to follow up inconclusive histology results were a feature in cases where patients were not recalled. A set of simple management guidelines has been drawn up. Amongst general gynaecological admissions 1 in 12 of all first trimester complications was an ectopic pregnancy. Amongst apparently true uterine miscarriages 20% of histological examinations were inconclusive and histology and ultrasound examinations failed to confirm a uterine miscarriage in 14% of apparently true missed miscarriages. Conclusions-Ectopic pregnancy is common amongst first trimester complications. Adherence to simple management guidelines would minimize the number of patients requiring emergency admission, though up to 20% of patients with apparently true uterine miscarriages would also require further investigation.
