Ectopic pregnancy--a new surgical epidemic.

Between March 1972 and September 1981, 154 patients with the diagnosis of ectopic pregnancy were treated at the University of Arizona. A retrospective review of these cases was performed to determine etiologic and demographic factors. Fertility follow-up was obtained in 58 women. Findings are discussed along with the presentation of various thoughts in an attempt to explain this proliferation of a surgical disease.
