Combined use of serial serum human chorionic gonadotropin testing, ultrasound and panoramic diagnostic microhysteroscopy in the early diagnosis of ectopic pregnancy.

It is not always easy to make an early diagnosis of ectopic pregnancy in patients with suspected ectopic pregnancy who in any case appear to be clinically stable, and in whom the serial serum study of human chorionic gonadotropin (hCG) testing and ultrasound (US) showed an abnormal pregnancy without adding any useful information for obtaining a differential diagnosis between ectopic pregnancy and non-viable intrauterine pregnancy (IUP). Typical management of these patients comprises expectant observation or carrying out a diagnostic laparoscopy. The purpose of this study was to examine the value of microhysteroscopy as an adjunctive procedure in the above-mentioned patients; the results of this clinical test show that in these patients, the microhysteroscopy may represent a simple and valid alternative to expectant observation or immediate laparoscopy.
