Laparoscopic management of rudimentary horn pregnancy. A case report.

BACKGROUND: Rudimentary uterine horn pregnancy is a very rare condition. Removal of a rudimentary horn is required as soon as a pregnancy is confirmed because most pregnancies in a rudimentary uterine horn rupture in the first or second trimester.

CASE: A 22-year-old woman was admitted to our hospital because an ectopic pregnancy was suggested by ultrasonographic examination at another hospital. A rudimentary uterine horn pregnancy was suspected from transvaginal ultrasonography. The patient was treated with laparoscopic surgery at 7 weeks of gestation. The pregnant rudimentary horn was removed laparoscopically by use of an automatic stapling device. The postoperative course was uneventful.

CONCLUSION: This is the first report of laparoscopic resection of a pregnant rudimentary uterine horn. Laparoscopic management of such a pregnancy may reduce operating time and peritoneal damage.
