Chronic interstitial ectopic pregnancy presenting with a negative urine pregnancy test.

The ampulla portion of the fallopian tube is the most common site of ectopic pregnancy (70%), with approximately 2% of pregnancies implanted in the interstitial portion. In general, an interstitial ectopic pregnancy (IEP) is difficult to diagnose and is associated with a high rate of complications-most patients with an IEP present with severe abdominal pain and haemorrhagic shock due to an ectopic rupture. Chronic tubal pregnancy (CTP) is an uncommon condition with an incidence of 20%. The CTP has a longer clinical course and a negative or low level of serum beta-human chorionic gonadotropin due to perished chorionic villi. This study presents a case of a woman who was diagnosed with a chronic IEP (CIEP) which was successfully treated by surgery. This case also acts as a cautionary reminder of considering a CIEP in women of reproductive age presenting with amenorrhea, vaginal bleeding and a negative pregnancy test.

Laparoscopic resection of a salpingectomy stump remnant during early pregnancy: the diagnostic challenge posed in diagnosing a heterotopic stump pregnancy.

In this report, we present a case of a woman admitted in her first trimester of pregnancy with significant intraperitoneal haemorrhage from a left tubal stump remnant occurring concurrent to a viable intrauterine pregnancy. The patient was resuscitated and treated successfully with laparoscopic removal of her stump remnant to achieve haemostasis. However, despite extensive investigation, the pathology of her haemorrhagic stump remained inconclusive. Stump ectopic pregnancy is an established phenomenon, although it presents a diagnostic challenge when occurring as a heterotopic pregnancy. Further, persisting trophoblastic tissue is a rare but established feature of incomplete removal of ectopic pregnancy post salpingectomy. Here, we discuss challenges of diagnosis in such cases and present a case report of a presumed stump remnant heterotopic pregnancy from spontaneous conception.

Successful management of an advanced interstitial ectopic pregnancy in a resource-limited setting: a case report.

BACKGROUND: Interstitial ectopic pregnancy is an ectopic gestation developing in the uterine part of the fallopian tube. The condition is rare and presents challenges for clinical as well as radiological diagnosis. This case report presents a rare case of interstitial ectopic pregnancy diagnosed intraoperatively. CASE PRESENTATION: A 36-year-old Black woman, referred from a peripheral health facility, presented at the emergency department with severe abdominal pains, vaginal spotting, nausea, and vomiting, with a 2-month history of irregular menstrual flow. Clinical and laboratory findings were suggestive of an acute abdomen likely due to a ruptured ectopic pregnancy (ultrasound was not available). An emergency exploratory laparotomy was done, which revealed a right adnexal ruptured interstitial pregnancy of a lifeless female fetus weighing 500 g (estimated mean gestational age of 22-23 weeks). The left fallopian tube looked normal. The site of rupture was repaired, followed by cleaning and closure of the abdomen. The post-operative period was uneventful, and the patient was discharged on postoperative day 7. CONCLUSION: Interstitial pregnancies are uncommon and rarely attain advanced gestational ages, as in this case, compared with other tubal ectopic pregnancies. However, women presenting with signs of hypovolemic shock and acute abdomen, with a positive pregnancy test, warrant a high index of suspicion.

Unusual presentation of late-stage ectopic tubal pregnancy (19 weeks' gestation): Case report and literature review.

Ectopic pregnancy is a medical condition in which a fertilized egg takes an unexpected detour away from the uterine cavity and the fallopian tube becomes a popular host, with the ampulla being the prime location. However, it can occur in other areas such as cervix, ovaries, or abdomen. The most common risk factors are pelvic inflammatory disease, previous pelvic or abdominal surgery, abnormal anatomy of genital organs, endometriosis, previous ectopic pregnancies, assisted reproductive technologies, endocrine disorders, and even the subtle influence of low-dose progestins from contraceptives. We will present a rare case of unrecognized late-stage tubal ectopic pregnancy. The following case report is of a 25-year-old Caucasian female patient (G2, P0) who presented to the emergency department with a 24-hour abdominal pain syndrome. The patient did not have a gynecological examination for this reason. During the examination, taking into account the clinical and ultrasound findings, a suspicion of pregnancy in a bicornuate uterus was raised, and an MRI of the pelvis was performed. MRI showed ectopic pregnancy in the left fallopian tube with a properly developed fetus that corresponded to a gestation of 19 weeks. An emergency laparotomy was performed and the left fallopian tube with the fetus was removed. The early and late course of recovery went smoothly. The patient was discharged after adequate clinical development.

Methotrexate treatment for peritoneal trophoblastic implants after laparoscopic salpingectomy and secondary laparoscopic excision of ectopic pregnancy.

Ectopic pregnancy is a one of the primary causes of maternal mortality in first trimester. The most common site of ectopic pregnancy is the fallopian tube. Surgical management of tubal ectopic pregnancy includes salpingotomy or salpingectomy. Persistent ectopic pregnancy can happen after salpingotomy due to incomplete removal of ectopic tissue. However, it is very rare after salpingectomy. In our case, the patient had right-sided salpingectomy and histology confirmed right-sided tubal ectopic pregnancy. She presented 19 days' later with abdominal pain, haemoperitoneum and persistent high beta-HCG (B-HCG). A second laparoscopy was done and tissue implants were removed from the surface of the right ovary and the omentum, which were confirmed to be products of conception on histology. The pain settled postoperative. However, B-HCG remained high postoperative. Subsequently, methotrexate treatment was given leading to full resolution of the pregnancy with one dose.

Evaluation of Clinical Efficacy of Contrast-Enhanced Ultrasound in the Diagnosis of Ectopic Tubal Pregnancy.

Objective: To explore whether contrast-enhanced ultrasound (CEUS) can improve tubal ectopic pregnancy detection rate, tubal dilation, tubal hematoma, and gestational sac. Methods: This retrospective study included 34 patients with suspected ectopic pregnancy who underwent contrast-enhanced ultrasound at Dongzhimen Hospital of Beijing University of Chinese Medicine between March 2021 and September 2016. Of these, 27 patients were confirmed to have tubal pregnancy by laparoscopic surgery and histopathology. Four ultrasound physicians (2 experts and 2 non-experts) conducted a retrospective analysis of conventional color Doppler ultrasound and the combination of conventional color Doppler ultrasound with contrast-enhanced ultrasound (color Doppler ultrasound + CEUS). They analyzed the differences in confidence levels and reproducibility in identifying tubal dilation, tubal hematoma, and gestational sac implantation sites. Additionally, the characteristic features of ectopic pregnancy on contrast-enhanced ultrasound were summarized, including gestational sac morphology, triple ring sign, enhancement patterns (branching or punctate), tubal dilation (with or without hematoma), contrast enhancement of tubal walls, and presence of free fluid. Results: In the expert group, the correct identification rate of the gestational sac implantation site on ultrasound images increased from 13/34 (38.2%) with conventional color Doppler ultrasound to 20/34 (58.8%) with color Doppler ultrasound + CEUS, the differences were statistically significant (38.2% vs. 58.8%, P = .039). The correct identification rate of tubal dilation increased from 6/34 (17.7%) to 25/34 (73.5%) (P = .001), and the correct identification rate of tubal hematoma increased from 3/34 (8.8%) to 17/34 (50.0%) with color Doppler ultrasound + CEUS (P < .001). In the non-expert group, the correct identification rate of the gestational sac implantation site increased from 8/24 (23.5%) with conventional ultrasound to 19/34 (55.9%) with ultrasound + CEUS (P = .003). The correct identification rate of tubal dilation increased from 6/34 (17.7%) to 23/34 (67.7%) (P < .001), and the correct identification rate of tubal hematoma increased from 3/34 (8.82%) to 12/34 (35.3%) with color Doppler ultrasound + CEUS (P = .012). Conclusion: The analysis of contrast-enhanced ultrasound images provides characteristic features and diagnostic points for tubal ectopic pregnancy, including gestational sac, thick ring sign, tubal dilation, and tubal dilation with hematoma. This approach improves the accuracy of partial pregnancy of unknown location (PUL) diagnosis and reduces the technical dependence on ultrasound personnel.

Expectant management of tubal pregnancies with human chorionic gonadotropin up to 2000 mIU/mL.

OBJECTIVE: To describe outcomes of expectant management (EM) versus methotrexate (MTX) treatment in tubal pregnancies with pretreatment human chorionic gonadotropin (hCG) less than 2000 mIU/mL. METHODS: This retrospective cohort from two tertiary hospitals included women with confirmed tubal pregnancies and pretreatment hCG <2000 mIU/mL. Exclusion criteria were unrecorded pregnancy site, unconfirmed diagnosis, and surgical treatment upon diagnosis. The primary outcome was eventual rate of surgical treatment. RESULTS: Between December 2009 and June 2021, 545 of 2114 (25.8%) women diagnosed with a tubal pregnancy met our inclusion criteria. We compared women who underwent EM (N = 201) with women who received MTX (N = 344). All women in the EM group had a declining trend of hCG. The MTX group had higher pretreatment hCG and higher rates of yolk sac or embryo presence on ultrasound. Eventual surgical treatment rate was higher in the MTX group compared with the EM group (39 [11.3%] vs. 9 [4.5%], P = 0.006), with no difference in the treatment failure rate or tubal rupture rate. In a subgroup analysis of women with pretreatment hCG between 1000 and 2000 mIU/mL, eventual surgical treatment, treatment failure, and tubal rupture rates did not differ between groups. Logistic regression analysis revealed that eventual surgical treatment was independently associated with hCG levels less than 1000 mIU/mL (adjusted odds ratio [aOR] 0.28, 95% confidence interval [CI] 0.14-0.56) and endometriosis (aOR 9.20, 95% CI 3.55-23.81). CONCLUSION: Expectant management of tubal pregnancies with pretreatment hCG levels less than 2000 mIU/mL and even between 1000 and 2000 mIU/mL and with a declining trend of hCG demonstrated lower or comparable rates of eventual surgical treatment, when compared with MTX treatment.

Hospital Volume and Quality of Care for Emergency Gynecologic Care.

OBJECTIVE: To evaluate the association between hospital volume and the quality of gynecologic emergency care for tubal ectopic pregnancies, ovarian torsion, and pelvic inflammatory disease (PID). METHODS: In this cross-sectional analysis, we analyzed patients who presented for emergency care for tubal ectopic pregnancies, ovarian torsion, and PID using the Premier Healthcare Database from 2006 to 2020. We measured the following outcomes: methotrexate use for ectopic pregnancy, ovarian cystectomy for torsion, and guideline-based antibiotic use for PID. For each condition, we measured outlier hospitals that performed the above interventions at below the 10th percentile. Multivariable logistic regression models were used to analyze associations between outlier care and hospital factors such as annualized mean case volume, urban or rural location, teaching status, bed capacity, and geographic region, as well as hospital-level patient population factors, including age, insurance status, and race. RESULTS: A total of 602 hospitals treated patients with tubal ectopic pregnancies, of which 21.9% were outliers, with no cases managed with methotrexate. Of 512 hospitals treating patients with ovarian torsion, 17.4% were outliers, with no cases managed with cystectomy. Of 929 hospitals that treated patients with PID, 9.9% were deemed outliers with low rates of guideline-adherent antibiotic administration. Low-volume hospitals were more likely to be outliers with low rates of use of methotrexate for ectopic pregnancy (6.7% of high-volume hospitals vs 49.7% of low-volume hospitals were outliers; adjusted odds ratio [aOR] 0.13, 95% CI, 0.05-0.31 for high-volume hospitals) and cystectomy for torsion (34.9% of low-volume vs 2.4% of high-volume hospitals were outliers; aOR 0.05, 95% CI, 0.01-0.18 for high-volume hospitals). There was no association between hospital volume and lower rates of guideline-based antibiotic use for PID. CONCLUSION: Higher hospital volume is associated with use of conservative, fertility-preserving treatment of emergency gynecologic conditions, including ectopic pregnancy and ovarian torsion.

[High expression of long noncoding RNA UCA1 promotes invasion, migration and epithelial-mesenchymal transition of trophoblasts in vitro].

OBJECTIVE: To investigate the role of urothelial carcinoma antigen 1 (UCA1) in regulation of invasion, migration and epithelial-mesenchymal transition (EMT) of trophoblast HTR-8/SVneo cells and its association with tubal pregnancy. METHODS: Cultured HTR- 8/SVneo cells stimulated with interleukin-6 (IL-6) were examined for changes in UCA1 expression and cell migration ability using qRT-PCR and scratch assay, respectively. A HTR-8/SVneo cell model with UCA1 silencing was constructed by transient transfection, and the migration and invasion abilities of the cells were assessed using Scratch assay and Transwell assay; qRT-PCR and Western blotting were performed to detect the mRNA and protein expression levels of EMT markers. RESULTS: HTR-8/SVneo cells stimulated with IL-6 exhibited significantly increased migration ability and up-regulated expression of UCA1 (P < 0.01). UCA1 silencing obviously suppressed migration and invasion abilities of HTR-8/SVneo cells (P < 0.01), significantly up-regulated the mRNA and protein expressions of EMT epithelial marker E-cadherin (P < 0.01), and down-regulated the expressions of the mesenchymal markers integrin ß3, vimentin and N-cadherin (P < 0.05). CONCLUSION: UCA1 may be a key gene that promotes the occurrence of tubal pregnancy and thus provides a new therapeutic target for tubal pregnancy.

[Interstitial ectopic pregnancy: report of an unusual location]. / Embarazo ectópico cornual: reporte de una localización inusual.

Ectopic pregnancy occurs when a developing blastocyst implants at any site other than the uterine cavity. Ectopic pregnancy is most commonly found in the fallopian tube but may also occur in the cornua of the uterus (also found as interstitial in the literature), cervix, ovary, or abdominal cavity or in a cesarean scar. An estimated 2% of pregnancies are ectopic, of which an interstitial pregnancy represents an extremely rare variant of ectopic pregnancy (EP), accounting for 2% to 4 % of all cases. The aim of this report is to describe the case of a patient with suspected ectopic pregnancy of uncertain location in which an exploratory laparoscopy was performed due to the onset of symptoms, discovering a cornual ectopic pregnancy in site of a past salpingectomy because of a tubal ectopic pregnancy. A cornuotomy by laparoscopy was performed to resect the cornual ectopic pregnancy. The patient had an uneventful postoperative course, with negativization of human chorionic gonadotropin levels. This type of location is rare and is associated with high rates of maternal morbidity and mortality. It represents a diagnostic and therapeutic challenge for the gynecologist who faces it.

Se define a un embarazo ectópico cuando el blastocisto en desarrollo se implanta fuera de la cavidad uterina. La localización más frecuente es en la trompa, pero también puede ocurrir en el ovario, cérvix, cicatriz de cesárea, cuerno uterino (también mencionado como intersticial en la literatura) o abdominal. Se estima que la incidencia de embarazo ectópico es aproximadamente el 2% de todos los embarazos, siendo la localización cornual solo el 2-4% de esos casos. El objetivo de este reporte es describir el caso de una paciente con sospecha de embarazo ectópico de localización incierta a quien se le realizó una laparoscopia exploradora por inicio de síntomas, evidenciando un embarazo ectópico cornual en el lecho de una salpingectomía, producto de un embarazo ectópico tubario previo. Se realizó la cornuotomía con resección del mismo por laparoscopia y su evolución fue favorable con negativización de la subunidad beta. Este tipo de localización es rara y se asocia con grandes tasas de morbimortalidad materna. Representa un desafío diagnóstico y terapéutico para el ginecólogo que lo enfrenta.

[Management of tubal ectopic pregnancies with methotrexate : is it an effective treatment ?] / La prise en charge des grossesses extra-utérines tubaires par méthotrexate : un traitement efficace ?

Ectopic pregnancy is a gynecological emergency. The hCG level, the clinical presentation and the ultrasound remain the key steps for the diagnosis. The criteria tend to be more and more codified to decide on the optimal treatment, however, there is no consensus. The aim of this study was to evaluate the impact of applying a mathematical formula to predict the failure rate of metho-trexate for tubal ectopic pregnancy. A retrospective, monocentric study was conducted on a cohort of 193 patients for whom the formula could be calculated. Regarding our professional practice, the success rate of first-line metho-trexate is 93 %. It would increase to 96 % if the formula had been applied. The use of the formula would also reduce the rate of first-line surgery by 12 %.

La grossesse extra-utérine est une urgence gynécologique. Le taux d'hCG, la clinique et l'échographie restent les examens clé pour le diagnostic. Les critères tendent à être de plus en plus codifiés pour décider du traitement optimal. Cependant, il n'existe aucun consensus. Le but de cette étude était d'évaluer l'impact de l'application d'une formule mathématique permettant de prédire le taux d'échec du méthotrexate pour une grossesse extra-utérine tubaire. Une étude rétrospective et monocentrique a été menée sur une cohorte de 193 patientes pour lesquelles la formule a pu être calculée. Concernant notre pratique professionnelle, le taux de réussite du méthotrexate en 1ère intention est de 93 %. Il passerait à 96 % si la formule avait été appliquée. L'emploi de la formule permettrait également de diminuer de 12 % le taux de chirurgie réalisée en première intention.

Treatment outcomes of tubal pregnancy with tubal preservation: A meta-analysis.

BACKGROUND: Ectopic pregnancy is a common gynecological emergency that poses a significant risk of maternal mortality during the first trimester. It also increases the incidence of infertility and repeated ectopic pregnancy. The aim of this study was to evaluate whether there is a difference in the degree of tubal patency between salpingostomy and systemic treatment with methotrexate (MTX), as well as the odds of intrauterine pregnancy and repeat ectopic pregnancy, and the degree of tubal patency in salpingectomy with or without tubal suturing. METHODS: We searched PubMed, EMBASE, and the Cochrane Library up to April 2023. Four randomized controlled trials were included in the review. We analyzed the combined data using Review Manager 5.3 software and Stata 12.0 software, utilizing a random effects model. RESULTS: When comparing salpingostomy and systemic treatment with MTX, there was no significant difference in the degree of tubal patency (OR = 1.09, 95% CI (0.54-2.38), P = .83). For salpingostomy with or without tubal suturing, there were no significant differences in the rates of intrauterine pregnancy, repeat ectopic pregnancy, and tubal patency degree [(OR = 1.05, 95% CI (0.41-2.68), P = .92), (OR = 0.68, 95% CI (0.19-2.42), P = .92), (OR = 1.68, 95% CI (0.14-20.33), P = .68)]. CONCLUSION: This meta-analysis demonstrates that systemic treatment with MTX is an effective treatment for patients who wish to preserve their fallopian tubes without undergoing surgery. This form of treatment can help avoid surgical procedures that may damage the fallopian tubes and improve fertility prospects. If choosing surgery, we believe that opting for salpingostomy without tubal suturing could reduce the operation time and minimize damage.

Prognostic factors for spontaneous resolution of an ectopic pregnancy.

OBJECTIVE: To identify factors that can accurately predict the spontaneous resolution of an ectopic pregnancy. STUDY DESIGN: This retrospective cohort analysis was conducted in the Department of Gynecology of a tertiary, university-affiliated medical center. Patients admitted to the center from January 2015 to July 2022 with a tubal ectopic pregnancy who met the criteria for expectant management were included. Beta-human chorionic gonadotropin (ß-hCG) levels were assessed at admission and at subsequent 24-hour intervals. Patients with declining levels were discharged for routine ambulatory ß-hCG follow-up until levels became undetectable. Patients who achieved a successful outcome were designated as the "spontaneous resolution group," while patients who underwent further hospitalization for methotrexate or surgery constituted the" failure group". Demographic, clinical, laboratory, and ultrasound parameters collected at first admission were compared between groups. RESULTS: Among the initial group of 210 eligible patients, 7 were lost to follow-up, 161 achieved spontaneous resolution, and 42 were readmitted for active intervention. Multivariate logistic regression analysis revealed that the last ß-hCG level before discharge (last ß-hCG) and the ratio between ß-hCG at discharge to ß-hCG at admission were the only independent parameters to predict outcomes. Patients with ß-hCG < 650 IU/L at discharge and a decline of 50% or more in ß-hCG level during hospitalization, had a 97% success rate with expectant management. Patients with ß-hCG discharge levels ≥ 1,000 IU/L had a 50% chance of success, regardless of whether their ß-hCG levels had declined. For all other patients, a 76% success rate was found. CONCLUSION: Short-term, serial ß-hCG follow-up at the initial presentation can help predict the spontaneous resolution of an ectopic pregnancy.

Prediction of Rupture by Complete Blood Count in Tubal Ectopic Pregnancies Treated with a Single-Dose Methotrexate Protocol.

OBJECTIVE: The availability of reliable and inexpensive markers that can be used to determine the risk of rupture during methotrexate (MTX) treatment in ectopic pregnancies (EPs) is considerable. The aim of the present study is to investigate the role of systemic inflammatory markers such as leukocytes (or white blood cells, WBCs), the neutrophil-to-lymphocyte ratio (NLR), and platelet distribution width (PDW), which are among the parameters of the complete blood count (CBC), in the prediction of rupture of EPs under MTX treatment. MATERIALS AND METHODS: A total of 161 patients with tubal EP who underwent a single-dose methotrexate (MTX) protocol were retrospectively analyzed, and the control group (n = 83) included patients cured by MTX, while the ruptured group (n = 78) included patients who were operated on for tubal rupture during the MTX treatment. The features of EP, beta-human chorionic gonadotropin (ß-hCG) levels, sonographic findings, and CBC-derived markers such as WBC, NLR, and PDW, were investigated by comparing both groups. RESULTS: The NLR was found to be higher in the ruptured group, of 2.92 ± 0.86%, and significantly lower in the control group, of 2.09 ± 0.6%. Similarly, the PDW was higher (51 ± 9%) in the ruptured group, and it was significantly lower a (47 ± 13%) in the control group (p < 0.05). Other CBC parameters were similar in both groups (p > 0.05). CONCLUSION: Systemic inflammation markers derived from CBC can be easily applied to predict the risk of tubal rupture in Eps, since the CBC is an inexpensive and easy-to-apply test, which is first requested from each patient during hospitalization.

OBJETIVO: A disponibilidade de marcadores confiáveis e baratos que podem ser usados para determinar o risco de ruptura durante o tratamento com metotrexato (MTX) em gestações ectópicas (GEs) é considerável. O objetivo do presente estudo é investigar o papel de marcadores inflamatórios sistêmicos, como leucócitos (ou glóbulos brancos, glóbulos brancos), a relação neutrófilo-linfócito (NLR) e largura de distribuição de plaquetas (PDW), que estão entre os parâmetros do hemograma completo (hemograma), na predição de ruptura de PEs sob tratamento com MTX. MATERIAIS E MéTODOS: Foram analisados retrospectivamente 161 pacientes com EP tubária submetidas a protocolo de dose única de metotrexato (MTX), sendo que o grupo controle (n = 83) incluiu pacientes curadas com MTX, enquanto o grupo roto (n = 78) incluíram pacientes operadas por ruptura tubária durante o tratamento com MTX. As características de EP, beta-gonadotrofina coriônica humana (ß-hCG), achados ultrassonográficos e marcadores derivados de CBC, como WBC, NLR e PDW, foram investigados comparando os dois grupos. RESULTADOS: A RNL foi maior no grupo roto, de 2,92 ± 0,86%, e significativamente menor no grupo controle, de 2,09 ± 0,6%. Da mesma forma, o PDW foi maior (51 ± 9%) no grupo roto, e foi significativamente menor a (47 ± 13%) no grupo controle (p < 0,05). Outros parâmetros do hemograma foram semelhantes em ambos os grupos (p > 0,05). CONCLUSãO: Marcadores inflamatórios sistêmicos derivados do hemograma podem ser facilmente aplicados para predizer o risco de ruptura tubária na Eps, uma vez que o hemograma é um exame de baixo custo e fácil aplicação, solicitado primeiramente a cada paciente durante a internação.

Large unruptured tubal pregnancy mimicking abdominal pregnancy.

Ectopic pregnancy accounts for 1-2% of all pregnancies. Ultrasound is the primary diagnostic tool to locate pregnancy outside the uterus and identify complications such as haemoperitoneum. In inconclusive cases, MRI is an adjunctive imaging modality offering more precise tissue differentiation and helpful to location identification. Presented is an unusual case of tubal pregnancy. The patient in her 30s, who was 14 weeks into her first pregnancy, had a suspected abdominal pregnancy. Both transabdominal ultrasound and an MRI indicated an ectopic pregnancy, likely originating from the right fallopian tube. A successful laparotomy and right salpingectomy were performed without complications. Rarely, as in this case, large unruptured and advanced tubal pregnancies can mimic an abdominal pregnancy, underscoring the importance of disease recognition and familiarity with uncommon image findings. An accurate diagnosis of pregnancy location is crucial for effective case management.

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.

Bilateral tubal pregnancy in a woman without risk factors.

In this case report, a woman with no risk factors was admitted with bilateral tubal ectopic pregnancy. Bilateral ectopic pregnancy is a rare clinical condition with clinical findings which in their symptoms do not differ from those of unilateral ectopic pregnancy. The condition can therefore easily be missed. The risk of rupture and haemorrhagic shock might be increased because of the increased danger of both tubes presenting with complications. Thus, it is important to examine both adnexa by transvaginal ultrasound. Even if unilateral ectopic pregnancy is considered before operation, the inspection of the abdomen, especially of the other fallopian tube, must always be done during surgery.
