Laparoscopic cornuotomy using a temporary tourniquet suture and diluted vasopressin injection in interstitial pregnancy

Objective: To evaluate the efficiency of laparoscopic cornuotomy. Design: Retrospective case review. Setting: An urban medical center. Patient(s): Eight patients with interstitial pregnancy who have undergone laparoscopic cornuotomy. Intervention(s): Laparoscopic cornuotomy was performed using a temporary tourniquet suture and the injection of diluted vasopressin around the cornual mass. The tourniquet suture was removed completely after repairing the cornu. Main Outcome Measure(s): Operating time, hemorrhage, beta-hCG levels. Result(s): The estimated blood loss was 50 +/- 22 mL (mean +/- SD), and the operating time was 58 +/- 46 minutes. The serum beta-hCG level returned to within the normal range approximately 4 weeks postoperatively in all patients. There were no major postoperative complications, such as hemorrhage, and no postoperative adjuvant therapy was required. Conclusion(s): Laparoscopic cornuotomy is a safe and effective method in interstitial pregnancy, and we believe that,it has the advantage of preserving reproductive capacity over cornual resection.
