Laparoscopic Management of 42 Cases of Tubal Stump Pregnancy and Postoperative Reproductive Outcomes.

STUDY

OBJECTIVE

Tubal stump pregnancy is a rare variant of ectopic pregnancy. The aim of this study was to evaluate laparoscopic surgery for tubal stump pregnancy and to investigate postoperative pregnancy outcomes.

DESIGN

Retrospective study.

SETTING

University-affiliated hospital.

PATIENTS: Patients (n = 42) diagnosed with tubal stump pregnancy.

INTERVENTIONS: Data were extracted from the electronic medical records system of the hospital.

MEASUREMENTS AND MAIN

RESULTS

Patients diagnosed with tubal stump pregnancy between June 2010 and July 2018 were included. Data included demographic characteristics, gravidity and parity, history of pelvic surgery, clinical features, and treatment. All procedures were laparoscopic. Postoperative pregnancy outcomes were identified from electronic medical records or by telephone. Patients' mean age was 30 (range, 21-39) years. Twelve of 42 tubal stump pregnancies (28.6%) had ruptured ectopic pregnancy at the time of operation. The remaining 30 cases had intact stump pregnancy during surgery. Patients were followed for a mean of 31 (range, 10-60) months. Follow-up data were available for 33 of 39 patients (3 with heterotopic tubal stump pregnancy were not included in follow-up data because all resulted in a live births and had no desire for future pregnancy). Eighteen of 28 patients (64.3%) who attempted conception had intrauterine pregnancies (IUPs) during the follow-up period; of these 18 IUPs, 14 (77.8%) resulted in live births. There was 1 case of uterine rupture in a singleton pregnancy at 20+5 weeks that resulted in fetal death. Three of 18 IUPs (16.7%) ended in the first trimester with spontaneous abortions.

CONCLUSION

Laparoscopic surgery is a feasible option for tubal stump pregnancy and is associated with favorable pregnancy outcomes.
