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 investigate postoperative pregnancy outcomes. DESIGN A retrospective study. SETTING A 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 years (range, 21-39 years). Twelve of 42 (28.6%) tubal stump pregnancies 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 31 months (range, 10-60 months). Follow-up data were available for 33 of 39 patients (3 cases of heterotopic tubal stump pregnancy were not included in follow up data because all resulted in a live birth and had no desire for future pregnancy). Eighteen of 28 (64.3%) patients who attempted conception had intrauterine pregnancies during the follow-up period; of these 18 intrauterine pregnancies, 14 (77.8%) resulted in a live birth. There was one case of uterine rupture in a singleton pregnancy at 20+5 weeks that resulted in fetal death. Three of 18 (16.7%) intrauterine pregnancies ended in the first trimester with spontaneous abortions. CONCLUSION Laparoscopic surgery is a feasible option for tubal stump pregnancy, associated with favorable pregnancy outcomes.
