Comparison of Laparoscopic Cornual Resection and Cornuotomy for Interstitial Pregnancy

Study Objective: To compare the clinical efficacy and safety of laparoscopic cornuotomy and cornual resection in the treatment of interstitial pregnancy. Design: Retrospective chart review between 2006 and 2014 (Canadian Task Force classification 11-2). Setting: Two academic tertiary care hospitals. Patients: Seventy-five patients with interstitial pregnancy treated by laparoscopy. Measurement and Main Results: In the 75 patients, 53 who underwent cornual resection and 22 who underwent cornuotomy, we evaluated operating time, changes in hemoglobin levels after surgery, the rate of major complications, and the incidence of persistent interstitial pregnancy. The mean operating time was significantly shorter for cornuotomy than for cornual resection (59.36 +/- 19.32 minutes vs. 77.11 +/- 23.97 minutes, respectively). Changes in hemoglobin level after the operation, rates of major complications, and the incidence of persistent interstitial pregnancy were not significantly different in the 2 surgery groups. Conclusion: Laparoscopic cornuotomy yielded clinical results comparable to those of cornual resection. Laparoscopic cornuotomy may reduce the time of operation, and had the same incidence of persistent interstitial pregnancy as cornual resection. (C) 2016 AAGL. All rights reserved.
