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 +/- 16 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.
