Recurrent Uterine Rupture After Laparoscopic Surgery for Interstitial Ectopic Pregnancy

Novel laparoscopic cornual resection of interstitial pregnancy using the Endo GIA™ Universal Stapler (Medtronic): A series of 12 cases

BACKGROUND

The maternal mortality of interstitial pregnancy is five times greater than that of other ectopic gestations due to potential haemorrhage. Minimal access surgical techniques usually comprise cornual resection and cornuostomy, requiring laparoscopic suturing skills.

AIM

To describe a case series using a laparoscopic automatic stapling device with reloadable cartridges to resect the cornu, enabling surgeons less familiar with intracorporeal suturing to avoid laparotomy when managing interstitial pregnancy.

MATERIALS AND METHODS

Twelve cases of laparoscopic cornual resections for interstitial pregnancies with the Endo GIA™ Universal Stapler (Medtronic) were collected prospectively over eight years. Outcome measures include human chorionic gonadotropin beta subunit (hβCG) levels, successful laparoscopic completion, estimated blood loss, intra-and post-operative complications and length of stay.

RESULTS

Median age and gestation at surgery were 31 years (range: 20-44) and eight weeks (range: 5-12), respectively. All involved live interstitial gestations, and 4/12 cases had significant haemoperitoneum at laparoscopy. The median blood loss was 300 mL (range 100-3500), and five women had blood loss >500 mL. The median serum hβCG level was 6429 IU/L (range: 1800-58690), and the median ectopic size was 4 cm (range 2-6). All cases were completed laparoscopically with no intra- or post-operative complications, although two women required blood transfusions. Median length of stay was 40 h. Further pregnancies could only be followed in 2/12 cases due to the migratory nature of our local population.

CONCLUSION

We describe a case series of 12 laparoscopic cornual resections for interstitial pregnancies using Endo GIA™ Universal Stapler, which simultaneously staples and transects the tissues, thus minimising the need for laparoscopic intracorporeal suturing.

Spontaneous rupture of the pregnant uterus following salpingectomy: a literature review

BACKGROUND

Spontaneous rupture of the uterus is a life-threatening obstetric complication in rare cases associated with previously performed salpingectomy.

AIM

This paper presents an analysis of uterine rupture cases during pregnancy in patients after surgical removal of the fallopian tubes.

METHODS

The English and Polish language literature was reviewed for studies published between January 1, 1980 and September 30, 2014 to identify articles that described rupture of the uterus in women with a previous history of salpingectomy.

RESULTS

Thirteen case reports and case series studies in 18 women were identified. 33% of cases of uterine rupture following salpingectomy occurred during intrauterine pregnancy, whereas the rest was associated with interstitial ectopic pregnancy. Laparoscopic salpingectomy more often resulted in rupture of the uterus during non-ectopic pregnancy as compared to laparotomy (4 vs. 2 cases, respectively). When interstitial pregnancies were excluded, uterine rupture was a cause of fetal death in 67% of reported gestations. There were no cases of maternal mortality. Conservative treatment was the preferred management option, and total hysterectomy was performed in only 2 patients.

CONCLUSION

Particular attention should be paid to patients with a previous history of salpingectomy due to the risk of uterine rupture throughout the entire pregnancy.
