Successful laparoscopic management of uterine serosal pregnancy

Management of a uterine serosal heterotopic pregnancy after in vitro fertilization in a woman with bilateral salpingectomy: A case report and literature review

RATIONALE

Heterotopic pregnancy (HP) is defined as the simultaneous presence of intrauterine pregnancy and ectopic pregnancy (EP). HP after bilateral salpingectomy is extremely rare and may lead to serious complications if it is misdiagnosed and untreated timely. Here, we presented the first reported case of uterine serosal HP in a woman after assisted reproductive technology with bilateral salpingectomy because of bilateral tubal ectopic pregnancy.

PATIENT CONCERNS

A 27-years-old pregnant woman after in vitro fertilization with bilateral salpingectomy complained of a sudden onset of unprovoked abdominal pain, which was persistent and dull. She denied vaginal bleeding.

DIAGNOSES

Serum beta-human chorionic gonadotropin levels are difficult to predict HP. Transvaginal ultrasonography demonstrated 1 gestational sac in the uterine cavity and 1 thick-walled cystic mass over the upper of the uterus, with a large amount of fluid in the Pouch of Douglas. Emergency laparotomy revealed a uterine serosal pregnancy combined with intrauterine pregnancy.

INTERVENTIONS

This patient was successfully managed via emergency laparotomy to remove residual tissue and repair the rupture of the uterine serosal pregnancy.

OUTCOMES

At postoperative 4 days, repeat transvaginal ultrosonography presented 1 intrauterine gestational sac with a visible fetal bud and cardiac tube pulsation. Now the patient recover well and is in an ongoing pregnancy.

LESSONS

It is noteworthy that HP/ectopic pregnancy is still not prevented after bilateral salpingectomy. In cases of multiple embryo transfer, even if intrauterine pregnancy has been established, it is important to rule out HP/ectopic pregnancy in time. Early diagnosis and early management can significantly improve clinical outcomes.

Abdominal pregnancy implanted on surface of pedunculated subserosal uterine leiomyoma: A case report

•

No case of abdominal pregnancy implanted on the surface of a subserosal uterine leiomyoma has previously been reported.

•

We herein report the case of abdominal pregnancy implanted on the surface of a pedunculated subserosal uterine leiomyoma.

•

The uterine leiomyoma with gestational tissue was resected laparoscopically and the postoperative course was uneventful.

Abdominal pregnancy is a rare form of ectopic pregnancy. Various sites of implantation in abdominal pregnancy have been reported. Uterine serosa is an extremely rare implantation site, with only a few cases reported to date. No case of abdominal pregnancy implanted on the surface of a subserosal uterine leiomyoma has been reported. We herein report the case of a 40-year-old primigravida woman who was diagnosed with abdominal pregnancy implanted on the surface of a pedunculated subserosal uterine leiomyoma. The uterine leiomyoma with gestational tissue was resected laparoscopically and the postoperative course was uneventful. It is necessary to remember the possibility of unexpected implantation sites and that laparoscopic surgery may be more difficult in such cases than that for fallopian tube pregnancy.
