Peritoneal pregnancy with massive hemoperitoneum in early gestation: two case reports

Management of non-tubal ectopic pregnancies analysis of a large tertiary center case series

PURPOSE

Ectopic pregnancies include cesarean scar (CSP), cornual and cervical pregnancies. Various treatment modalities have been- described, but no standardized procedure has been defined so far. The aim of our analysis was to evaluate the diagnostics and treatment at the Department of Obstetrics and Gynecology, LMU University Hospital, Munich.

METHODS

In this retrospective, single-center analysis, 24 patients treated between 2015 and 2020 were analyzed. After verification of the diagnosis by imaging and HCG-analysis, the treatment was individually determined: therapy with methotrexate (MTX) locally with or without simultaneous systemic treatment, surgical treatment via curettage, excision with uterine reconstruction even hemi hysterectomy.

RESULTS

Ten patients presented with CSP, six with cervical and eight with cornual pregnancies. Median age was 34.6 years. CSP was treated with local MTX in six cases; five required additional treatment with systemic MTX or curettage. Primary curettage or surgery was performed in four cases. In cervical pregnancies the primary therapy with local MTX injection and systemic treatment was performed in 50%. One patient was treated with MTX and insertion of a Bakri balloon. Trachelectomy was required in one case. 50% of cornual pregnancies were treated with MTX locally and intramuscularly and 50% received surgery.

CONCLUSION

Treatment strategies were based on the patient's individual risk parameters. The results of this study show, that simultaneous treatment with local and systemic MTX had good outcomes and could avoid surgeries.

Abdominal ectopic pregnancy following a frozen embryo transfer cycle: a case report

Background

Abdominal ectopic pregnancy (AEP) is a rare form of ectopic pregnancy. As the number of in-vitro fertilization (IVF) procedures continues to increase, the incidence of AEP will also rise. However, the rarity and atypical presentation of AEP make early diagnosis challenging.

Case presentation

Herein, we report an AEP following frozen-thawed embryo transfer (FET) in an artificial cycle. The patient was misdiagnosed with implantation failure when the serum human chorionic gonadotropin (hCG) level was detected as 2.59mIU/ml at fourteenth day after embryo transfer. Therefore, she was suggested to stop luteal phase support. However, a ruptured AEP was developed 33 days following embryo transfer, which was diagnosed by laparoscopic surgery.

Conclusions

The case highlighted the delayed serum β-hCG and massive intraperitoneal hemorrhage may be clues to make early diagnosis of AEP. Clinicians must attach great importance to close monitoring and bear in mind the possibility of abdominal pregnancy.

Spontaneously conceived heterotopic pregnancy with abdominal pregnancy implanted on the vesicouterine pouch: A case report and literature review

We report the case of a 36-year-old woman with spontaneously conceived heterotopic pregnancy with abdominal pregnancy. She visited the hospital at 5 weeks and 4 days of gestation and transvaginal ultrasonography revealed a normal intrauterine pregnancy. Two days later, she was urgently transported to the hospital due to extreme abdominal pain. Emergent laparotomy was performed to investigate the cause of massive intraperitoneal bleeding, which was confirmed to have been due to an abdominal pregnancy that implanted on the vesicouterine pouch. The hematic mass, including chorionic villi, was successfully removed from the peritoneum. The subsequent course of the intrauterine pregnancy was uneventful and a healthy baby was born at term. To the best of our knowledge, this is an extremely rare case report of a spontaneously conceived heterotopic abdominal pregnancy, in which the intrauterine pregnancy showed a successful outcome despite the collapse of the abdominal pregnancy at a very early stage.

Rare Ectopic Pregnancies - A Literature Review for the Period 2007 - 2019 on Locations Outside the Uterus and Fallopian Tubes

The majority of ectopic pregnancies (EP) are tubal pregnancies, but other implantation sites outside the uterus and tubes are also found. These rare EP locations present a particular diagnostic and therapeutic challenge. We present an overview of potential very rare locations of ectopic pregnancies, their symptoms, diagnosis and treatment, based on a systematic analysis of case reports. A literature review of the databases PubMed, Livivo and Google Scholar for the period 2007 to 2019 was carried out. A total of 113 publications were included in our review. These studies describe EP implantations in the posterior cul-de-sac, on the uterine serosa and uterine ligaments, in the vicinity of almost all intraperitoneal organs, on the abdominal wall as well as in retroperitoneal sites. The most common presenting symptom was abdominal pain occurring in different locations. The diagnostic procedures included various imaging procedures and/or explorative surgery at different advanced stages of pregnancy. The most common and preferred option was laparotomy for surgical treatment. The placenta was successfully resected in the majority of cases. A rare EP location should be considered when making a differential diagnosis in patients of child-bearing age with abdominal pain.
