Abdominal pregnancy: a case report and review of 17 cases

Ectopic pregnancy located at pelvic wall and liver: Two uncommon case reports from Vietnam and mini-review literature

INTRODUCTION AND IMPORTANCE

Abdominal ectopic pregnancy (AEP) located at hepatic region and pelvic-wall ectopic pregnancy (EP) are rare entities, that provoking a potentially life-threatening condition. Due to insufficient data, a proper management of non-specific types remains a challenge for all gynecologists worldwide.

CASE PRESENTATION

Two child-bearing age women were hospitalized due to delayed menstruation and a urine pregnancy test was positive without a determination of intrauterine pregnancy. The first EP case was located at the pelvic wall which identified incidentally during laparoscopy for a presumed tubal ectopic pregnancy on ultrasonography throughout. The second EP case was found at the hepatic region due to intermittent pain rising from the right upper quadrant region and serial ultrasonic findings. In our management, both cases were successfully assessed by laparoscopy and laparotomy without requiring further intervention, respectively.

CLINICAL DISCUSSION

An accurate diagnosis of EP location at liver and pelvic wall is totally difficult since its uncommon location. An initial assessment should be based on clinical symptoms and the treatment remains controversial. The surgical management including laparotomy and laparoscopy depends on clinical evaluation, experience of surgeon, and interdisciplinary team. Thus, these abnormal sites of ectopic pregnancy ought to take into consideration for all gynecologists in an emergency condition with a major hemorrhage.

CONCLUSIONS

In reproductive age women, primary EP at liver and pelvic wall should be considered with high index of suspicion if intrauterine pregnancy is totally excluded. Timely diagnosis, rational management by surgical excision, and a multidisciplinary team can reduce substantially adverse outcomes.

Challenges and perspectives of abdominal pregnancy in a resource-limited setting: A case series

INTRODUCTION AND IMPORTANCE

Abdominal pregnancies, although rare, present unique challenges in both diagnosis and management. This case series reports on four cases of abdominal pregnancies diagnosed in a remote and underserved region of the Democratic Republic of Congo, highlighting the difficulties encountered in an under-equipped environment.

CASE PRESENTATION

The cases were documented in a remote village of DRC, which lacks specialized medical personnel and relies heavily on traditional healers. We report here 4 cases of abdominal pregnancies, their clinical presentations, diagnostic modalities, and surgical approaches. The cases varied in terms of clinical symptoms, gestational age, and placental implantation sites. Delayed diagnosis and presentation were common, resulting in significant hemoperitoneum and adverse fetal outcomes. All cases required laparotomy for both diagnosis and intervention.

CLINICAL DISCUSSION

Abdominal pregnancies can go undetected until advanced gestational age, with common physical findings including abdominal tenderness, abnormal fetal lie, fetal body parts readily palpable, and a displaced cervix. Laboratory tests may raise suspicion, but treatment options depend on intraoperative findings and gestational age. Advanced abdominal pregnancies are associated with high mortality rates for both the mother and the fetus. Laparotomy is typically required for diagnosis and intervention, with variations in placental implantation sites. Management of the placenta remains a debated topic, with partial or complete removal both viable options.

CONCLUSION

Abdominal pregnancies pose significant challenges in resource-poor settings, where limited healthcare resources and a shortage of specialized medical personnel can impede early diagnosis and appropriate management. Enhancing prenatal care, improving diagnostic capabilities, and increasing awareness among healthcare providers and communities are essential for optimizing outcomes in these complex obstetric cases.

Chronicles of an uncommon term abdominal pregnancy with successful outcome: a case report

BACKGROUND

Intra-abdominal pregnancies, while rare, present with unique diagnostic and management challenges. We present a case of a 25-year-old para 2 + 1, black African woman, who was referred from a peripheral Health Centre level IV in the Northern part of Uganda to a Regional Referral Hospital due to an abnormal presentation with easily palpable fetal parts. This case emphasizes the significance of prompt diagnosis, interdisciplinary collaboration, surgical planning, and managing the placenta in advanced intra-abdominal pregnancies.

CASE PRESENTATION

A 25 year African black female, para 2 + 1 upon arrival at Regional Referral Hospital, a University Teaching Hospital during a weekend, an ultrasound was sourced from a nearby private clinic revealing an extra-uterine intra-abdominal pregnancy at 38 weeks of gestation and she was promptly sent back to the University Teaching Hospital. Following this diagnosis, the patient, who hailed from a remote village over 30 km away, returned to her family for discussions. After three days, she was readmitted. Emergency laparotomy unveiled an omental gestation sac with extensive placental attachment. A live female infant was delivered successfully, placenta was left in situ. The postoperative course was uneventful, with initial concerns about inadequate breast milk flow which resolved after placental removal during the second exploratory laparotomy.

CONCLUSION

This case highlights the uncommon occurrence of an advanced intra-abdominal pregnancies and emphasizes the importance of multi-disciplinary teamwork and placental management. The favorable outcome in the management was based on thorough assessment of the placental location, attachments and blood supply during surgery. It demonstrates the possibility of reduced risk of massive bleeding if there is a delayed removal of placenta with favorable attachment. This is particularly important for milk letdown as well as reducing the needs of blood transfusion in resource limited settings.

Abdominal ectopic pregnancy

An ectopic pregnancy (EP) accounts for 1-2% of all pregnancies, of which 90% implant in the fallopian tube. An abdominal ectopic pregnancy (AEP) is defined as an ectopic pregnancy occurring when the gestational sac is implanted in the peritoneal cavity outside the uterine cavity or the fallopian tube. Implantation sites may include the omentum, peritoneum of the pelvic and abdominal cavity, the uterine surface and abdominal organs such as the spleen, intestine, liver and blood vessels. Primary abdominal pregnancy results from fertilisation of the ovum in the abdominal cavity and secondary occurs from an aborted or ruptured tubal pregnancy. It represents a very rare form of an EP, occurring in <1% of cases. At early gestations, it can be challenging to render the diagnosis, and it can be misdiagnosed as a tubal ectopic pregnancy. An AEP diagnosed >20 weeks' gestation, caused by the implantation of an abnormal placenta, is an important cause of maternal-fetal mortality due to the high risk of a major obstetric haemorrhage and coagulopathy following partial or total placental separation. Management options include surgical therapy (laparoscopy±laparotomy), medical therapy with intramuscular or intralesional methotrexate and/or intracardiac potassium chloride or a combination of medical and surgical management. The authors present the case of a multiparous woman in her early 30s presenting with heavy vaginal bleeding and abdominal pain at 8 weeks' gestation. Her beta-human chorionic gonadotropin (bHCG) was 5760 IU/L (range: 0-5), consistent with a viable pregnancy. Her transvaginal ultrasound scan suggested an ectopic pregnancy. Laparoscopy confirmed an AEP involving the pelvic lateral sidewall. Her postoperative 48-hour bHCG was 374 IU/L. Due to the rarity of this presentation, a high index of clinical suspicion correlated with the woman's symptoms; bHCG and ultrasound scan is required to establish the diagnosis to prevent morbidity and mortality.

Abdominal pregnancy with a live newborn in a low-resource setting: A case report

Abdominal pregnancy is defined as pregnancy anywhere within the peritoneal cavity, exclusive of tubal, ovarian, or broad ligament locations. It is a rare form of ectopic pregnancy with high morbidity and mortality for both the mother and the fetus. Diagnosis can be frequently missed in low-resource settings because of poor antenatal healthcare provision, low socioeconomic patient status as well as lack of adequate medical resources. Clinical diagnosis can be difficult and ultrasound scan is helpful during the early stages of gestation but can be disappointing thereafter. A case of abdominal pregnancy in a 25-year-old woman, who presented at 26 weeks of gestation with severe abdominal pain not relieved by any medication, is reported. An emergency laparotomy was undertaken as her vital signs deteriorated. An abdominal pregnancy was found and a live neonate delivered. Ministries of health in developing countries should ensure routine access to ultrasound in early pregnancy. Obstetricians should bear in mind that abdominal pregnancy can present late in gestation.
