Cornual wedge resection for interstitial pregnancy and postoperative outcome

Area of Science:

• Reproductive Medicine
• Surgical Obstetrics
• Gynecologic Oncology

Background:

• Interstitial pregnancies were traditionally managed with hysterectomy or cornual resection via laparotomy.
• Laparoscopic cornuotomy is increasingly used for interstitial pregnancies, potentially preserving fertility but risking persistent/recurrent ectopic pregnancy and future uterine rupture.
• Cornual wedge resection is an alternative surgical approach for interstitial pregnancy management.

Purpose of the Study:

• To evaluate fertility outcomes after cornual wedge resection for interstitial pregnancy.
• To assess rates of subsequent uterine rupture and dehiscence following cornual wedge resection.
• To determine the incidence of persistent or recurrent interstitial pregnancy after cornual wedge resection.

Main Methods:

• Retrospective review of 29 cases of cornual wedge resection for interstitial pregnancy.
• Data collected from 1992 to 2013 at a single institution.
• Analysis of patient records for fertility, uterine rupture, and recurrence rates.

Main Results:

• No cases of persistent ectopic pregnancy or recurrent interstitial pregnancy were observed.
• Subsequent uterine rupture or scar dehiscence occurred in 30% of cases (2 out of 29).
• 71.4% of women attempting conception achieved a subsequent pregnancy.

Conclusions:

• Cornual wedge resection for interstitial pregnancy resulted in no recurrences but carried a significant risk of uterine rupture/dehiscence.
• While fertility was preserved for most patients, the risk of uterine complications necessitates careful consideration.
• The choice between cornual resection and cornuotomy for interstitial pregnancy requires individualized assessment.
