Cornual patency and integrity following laparoscopic cornuotomy for interstitial pregnancy

Objective: To evaluate cornual patency and integrity following laparoscopic cornuotomy. Study Design: This is a prospective cohort study on seven women who underwent laparoscopic cornuotomy for interstitial pregnancy. The cornual patency and integrity were evaluated using hysterosalpingography (HSG) and magnetic resonance imaging (MRI). On MRI, the entire cornual wall thickness was measured bilaterally at 5-mm intervals. The thickness of the affected and unaffected cornua matched at the corresponding contralateral point in each of the women. Statistically, all possible pairwise 28 comparisons were compared using paired t-tests. Results: Among six eligible women, four women had excellent cornual patency on the affected side. Among seven women (i.e., 28 pairs), no significant difference was observed in cornual thickness compared to the unaffected cornu and no remarkable defects were seen in the endometrial and cornual contour. But there is no statistical significance. Conclusion: Laparoscopic cornuotomy seems to have advantage to preserve the cornu in interstitial pregnancy.
