In order to gain greater insight into the diagnosis and management of ectopic pregnancies, a study of 153 cases seen and treated from 1960 to 1974 was undertaken. The ratio of ectopic pregnancy to deliveries was 1:146, the greatest incidence occurring in multiparous patients 26–30 years of age. The various types of ectopic pregnancies found among these women were: tubal, 136 (90.6%); cornual, 4 (2.7%); ovarian, 4 (2.7%); abdominal, 4 (2.7%); combined, 1 (0.7%); and unspecified, 1 (0.7%). Pain, amenorrhea and vaginal bleeding were the most common presenting signs and symptoms. Abdominal pain and tenderness, together with severe pain on pelvic examination and an adnexal mass or fullness, were the most significant physical findings. Culdocentesis was the most reliable technique for establishing the diagnosis of ectopic pregnancy, and total salpingectomy was the treatment of choice. The ectopic gestation was ruptured in 131 patients (87.3%) at the time of surgery. There were no maternal deaths.
