The purpose of this study was to evaluate whether endometrial thickness measurements can be used to differentiate between patients with ectopic pregnancy and spontaneous abortion. Of 676 patients with clinical suspicion of ectopic pregnancy, no intrauterine pregnancy was seen in 128. Of these, 42 (33%) had ectopic pregnancy, 52 (40%) had spontaneous abortion, and 34 (27%) had intrauterine pregnancy. No significant difference was found in endometrial thickness between women with ectopic pregnancy (mean, 9.0 mm; range, 2 to 20 mm) and those with spontaneous abortion (mean, 8.4 mm; range, 2 to 18 mm). A thin endometrium seen on transvaginal sonography cannot be used to exclude the diagnosis of ectopic pregnancy.
