Bilateral tubal pregnancy. A report of an unusual case.

BACKGROUND

Bilateral tubal pregnancies are rare and are usually confirmed simultaneously during the same operation. We report a case in which the right salpingectomy was performed seven weeks before the left salpingectomy. When the right salpingectomy was done, the left uterine tube appeared entirely normal.

CASE: A 38-year-old woman underwent laparoscopic surgery for suspected right tubal pregnancy. A right tubal pregnancy was found to have partially aborted into the peritoneal cavity. The left uterine tube was carefully inspected and appeared normal. Histopathology of the right tube showed products of conception and chorionic tissue. Seven weeks after surgery, the woman presented in hemorrhagic shock necessitating emergency laparotomy and left salpingectomy. Histopathology of the left tube confirmed the presence of chronic tissue. The patient did not have coitus between the two salpingectomies.

CONCLUSION

The explanation of the presentation is uncertain. However, this case underscores the importance of careful follow-up of patients after laparoscopic surgery for ectopic pregnancies.
