A case report of heterochronic presentation of a bilateral tubal pregnancy

Key Clinical Message

This paper highlights that diagnosis and treatment of one ectopic pregnancy does not rule out the happening of a second ectopic pregnancy in the same patient concurrently, especially if the patient has rising β-hCG and persistent symptoms.

Abstract

Bilateral tubal pregnancy (BTP) is the most uncommon form of tubal ectopic pregnancy. Complications can lead to maternal morbidity and mortality. We reported a case of left tubal pregnancy and the patient underwent laparoscopic salpingostomy. During the follow-up, the contralateral ectopic pregnancy was discovered and treated with MTX.

Ectopic pregnancy risk factors in infertile patients: a 10-year single center experience

The present retrospective study included both intrauterine insemination and in vitro assisted reproductive technologies (ART) procedures performed from January 2009 to December 2018 at a tertiary-care Fertility Centre. The purpose was to assess the incidence of ectopic pregnancy (EP) in infertile population who undergoes ART and to identify any risk factor impacting the occurrence of EP after ART. Among 27,376 cycles, 7352 pregnancies were achieved, of which 132 were EPs, the 1.80% (95% CI 1.5-2.1) of all pregnancies. In fresh embryo transfer cycles, a history of prior pelvic adhesions showed the greatest impact on the incidence of EP (aOR 2.49 95% CI 1.53-4.07 p < 0.001). Other factors associated with EP incidence were also identified, such as female age, basal FSH, the transfer of blastocyst embryos and difficulties during the embryo transfer procedure. In frozen embryo transfer cycles, the only factor influencing the incidence of EP was anti Müllerian hormone (AMH) serum concentration (aOR 0.81 95% CI 0.65-1.00, p = 0.048). To conclude, the incidence of EP observed was comparable to that reported after natural conception. On the other hand, pre-existing risk factors, traditionally more common in infertile population, appeared to influence the incidence of EP and should thus be modified if possible.

Comparisons of Fertility Outcomes Following a Salpingectomy and a Salpingotomy with or Without Suturing for a Tubal Ectopic Pregnancy

Objective

This study aimed to compare fertility outcomes in patients who underwent different laparoscopic surgeries and to determine the most beneficial surgical treatment for tubal ectopic pregnancy (EP) patients who wished to become pregnant in the future.

Methods

In this retrospective study, patients aged 18–36 years, who had been diagnosed with a tubal EP in our hospital, were enrolled. Based on the treatment methods, the patients were divided into three groups, ie a salpingectomy group, a salpingotomy with suturing group and a salpingotomy without suturing group. The follow-up time for the enrolled patients was more than three years. Serum beta (β)-human chorionic gonadotropin (β-HCG) levels were monitored after surgery. The intrauterine pregnancy (IUP) rate at 12, 24 and 36 months postoperatively, and recurrent EP rate were compared.

Results

The median time for β-HCG level returning to normal in the salpingectomy group was much shorter than in the salpingotomy with suturing or salpingotomy without suturing groups (P < 0.001). The 12, 24 and 36-month IUP rates among the three groups were not significantly different. A recurrent EP was found in only one patient in the salpingotomy with suturing group and two patients in the salpingotomy without suturing group.

Conclusion

In this study, we found that salpingectomy and salpingotomy with or without suturing methods reflected no significant differences in fertility outcomes for tubal EP patients.
