Conservative surgical management of interstitial pregnancy.

Conservative management of ampullary and isthmic tubal pregnancies has been increasingly advocated to preserve the affected tubes and results in excellent outcome. A similar approach to interstitial pregnancies is more difficult because of the vascularity of the cornual area. We report here a novel surgical approach to this problem in two patients. Both patients had an unremarkable postoperative course. Hysterosalpingograms performed 5 and 6 months postoperatively demonstrated bilateral tubal patency. It is suggested that conservative surgical management may replace either cornual resection or hysterectomy in selected patients with unruptured interstitial pregnancies.
