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.
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.
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.
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.
