Laparoscopic treatment of cornual heterotopic pregnancy: A retrospective cohort study.

OBJECTIVE

To report on our experience of laparoscopic cornuostomy or cornual repair for cornual heterotopic pregnancy.

STUDY

DESIGN

A single center, retrospective review of patients who were diagnosed as cornual heterotopic pregnancy, which developed after in vitro fertilization and embryo transfer (IVF/ET) between January 2009 and June 2014. All patients were managed by laparoscopic cornuostomy or cornual repair.

RESULTS

14 patients were enrolled and 4 patients were finally confirmed to have a ruptured cornu. 4/4 presented as acute abdominal pain and 3/4 as metrorrhagia. The blood pressure of all the patients were stable. The earliest ruptured patient of this series happened at 23 days after IVF/ET. The hemoglobin levels of the 4 ruptured patients were significantly lower than the other patients (8.6 ± 1.8 g/dl versus 12.2 ± 1.1 g/dl, p < 0.001). Internal bleeding before operation was significantly higher in the ruptured patients than in the intact patients (1050.0 ± 369.8 ml versus 0.0 ± 0.0 ml, p < 0.001). All 14 patients were managed by laparoscopic cornuostomy or cornual repair. No one was converted to laparotomy. Post-operation pregnancy was uneventful. All neonates were delivered by cesarean section with no evident complications.

CONCLUSION

Laparoscopic cornuostomy or cornual repair appears to be an effective treatment for cornual heterotopic pregnancy, even in ruptured ones. These operations can be safely performed in an institution with well-trained gynecological laparoscopists with experienced support teams.
