[A clinical study 39 cases of ovarian pregnancy].

Thirty-nine cases of ovarian pregnancy in our hospital from 1982 to 1992 were analyzed, and compared with the tubal pregnancies admitted during the same period. It showed that the incidence of ovarian pregnancy was 2.6% of all ectopic pregnancies with a trend to increase yearly. The clinical features of ovarian pregnancy revealed that abdominal pain was the major symptom, and history of amenorrhea was obscure. The clinical diagnosis of ovarian pregnancy was more difficult than that of tubal pregnancy. The typical histologic characteristics showed the embryo and chorionic villi surrounded by ovarian tissue or the presence of decidual changes. Ovarian pregnancy was closely related with poor uterine environment, pelvic inflammatory disease and/or endometriosis. The preferred therapeutic procedure was partial ovariectomy or wedge resection, preserving the normal ovarian tissue and tube as much as possible.
