Abstract

OBJECTIVE
Cornual or interstitial pregnancy rarely occurs. Its incidence is estimated 2-4% of all tubal pregnancy, but it causes serious maternal mortality and morbidity. The authors surveyed 37 cases with cornual pregnancy and propose analysis from the clinical statistical aspect.
METHODS
We studied 37 cases which have occured from May. 1, 1983 to Dec. 31, 1998 at Department of Obstetrics & Gynecology, College of Medicine, Yeungnam University, Daegu.
RESULTS
The incidence of cornual pregnancy was 1 in 35.1 ectopic pregnancies. Shock was more frequent, intra-abdominal hemorrhage below 500ml was 35.1%, above 2,000ml was 24.3%. The most frequent interval between LMP and the onset of symptom was 8-12 weeks in 54.1%. 70.3% of total cases were treated by cornual wedge resection, 24.3% by total abdominal hysterectomy.
CONCLUSION
Early detection of cornual pregnancy is essential in avoiding a fatal outcome. Although most of cornual pregnancies were treated with traditional operative techniques, it is useful to conduct conservative or non-conservative management by laparoscopy and treat medically.
