Trophoblastic Tissue Reimplantation below the Spleen Following Laparoscopic Bilateral Salpingectomy for Ectopic Tubal Pregnancy: A Case Report.

BACKGROUND: Trophoblastic tissue reimplantation after laparoscopic salpingectomy is a very rare complication. These cases may present a diagnostic challenge and the majority of patients need a surgical treatment. CASE PRESENTATION: A 31-year-old patient came to a tertiary referral center for nausea and pain in the upper left abdominal quadrant. Ultrasound and abdominal CT scan showed a 68 × 60 × 87 mm size heterogenic mass below the spleen with arterial extravasation from the lower spleen pole. Recent history of surgery for ectopic pregnancy and serum hCG testing allowed to diagnose extratubal secondary trophoblastic tissue reimplantation below the spleen. Embolization of the bleeding vessel and successful treatment with methotrexate was achieved. CONCLUSIONS: In cases of a nondisseminated trophoblastic tissue reimplantation, consider embolization and treatment with methotrexate if the patient is hemodynamically stable; thus, secondary surgical treatment is preventable.

Forensic Analysis of Eighteen Tubal Pregnancy-Related Medical Damage.

OBJECTIVES: To analyze the cases of medical damage after misdiagnosis of tubal pregnancy, to explore the causes of medical damage, the causal relationship between medical malpractice and the damage consequences, as well as the causative potency, in order to provide evaluation ideas for forensic identification of such cases. METHODS: Eighteen cases of forensic identification of tubal pregnancy related medical damage were collected and retrospectively analyzed from the aspects of age, maternity history, fertility requirements, risk factors, diagnosis and treatment, medical malpractice, damage consequences, and causative potency. RESULTS: All 18 cases were tubal pregnancy, of which 17 cases had medical malpractice, resulting in 14 cases of affected tubal resection, 2 cases of hemorrhagic shock death, 1 case of intrauterine fetal death and affected tubal resection. The other case had the consequence of affected tubal resection, but there was no malpractice in the treatment. CONCLUSIONS: Correct diagnosis is helpful to make appropriate treatment plan, prevent disease progression and reduce serious adverse consequences and the occurrence of medical disputes. Scientific and reasonable analysis of the causal relationship between medical malpractice and damage consequences and the causative potency is of great significance to the successful settlement of medical disputes.

Clinical analysis of women with ovarian pregnancy: a retrospective case-control study.

BACKGROUND: To address the clinical features and potential risk factors of ovarian pregnancy (OP). METHODS: In this retrospective case-control study performed in West China Second University Hospital from March 17, 2005 to December 8, 2018, 146 OP patients were selected as a case group, 292 patients with tubal pregnancy (TP) and 292 women with intrauterine pregnancy (IUP) were matched as controls at a ratio of 1:2:2. RESULTS: When compared with TP patients, OP patients tend to have worse clinical complications (hemorrhagic shock (7.41% vs 2.89%), rupture of pregnancy sac (54.07% vs 37.78%), hemoperitoneum (363.1 ± 35.46 ml vs 239.3 ± 27.61 ml) and increased need for emergency laparotomy (9.60% vs 3.97%) at an early gestational age. Assisted reproductive technology (ART) (adjusted OR1 2.08, 95%CI 1.04 to 4.18; adjusted OR2 2.59, 95%CI 1.25 to 5.37) and intrauterine contraceptive device (IUD) use (adjusted OR1 2.19, 95%CI 1.10 to 4.36; adjusted OR2 2.77, 95%CI 1.74 to 5.71) may be risk factors for ovarian ectopic pregnancy as compared to the control groups of TP and IUP patients. CONCLUSIONS: OP patients tend to have more severe clinical complications and this study has identified ART and IUD use as potential risk factors for OP. Results of this study may contribute to improve the understanding of OP and promote early surgical intervention.

Extratubal secondary trophoblastic implants (ESTI) following laparoscopic bilateral salpingectomy for ectopic pregnancy: problems that have been neglected for a long time.

Background: Extratubal secondary trophoblastic implants following laparoscopic salpingectomy is an extremely rare form of persistent ectopic pregnancy. These cases usually result in a small amount of vaginal bleeding and sudden lower abdominal pain thereby presenting with hemoperitoneum in emergencies. Owing to the urgency of hemoperitoneum and the uncertainty of the location of persistent ectopic pregnancy after laparoscopic salpingectomy, the risk of reoperation is increased. It is necessary to prevent in first surgery and diagnose these cases in the early following up phase.Methods: We report a case of 26-year-old woman, gravida 3, para 0, presenting a little vaginal bleeding and slight lower abdominal pain after laparoscopic bilateral salpingectomy for more than 1 month. The patient's serum ß-HCG was still high (3981 mIU/ml), and no abnormalities were found through auxiliary examination (ultrasound, abdominal CT, and pelvic MRI).Results: Finally, emergency laparoscopy revealed many blue purple nodules on the surface of ovaries, small intestine, omentum, and periumbilical peritoneum, with a diameter of 3-20 mm. The lesions were completely removed as far as possible. Pathology showed trophoblastic proliferation and ß-HCG soon decreased to negative after this operation.Conclusion: Therefore, it is important to follow up serum ß-HCG even after salpingectomy and avoid iatrogenic dissemination of trophoblast tissue through careful operation.

Heterotopic pregnancy after bilateral salpingectomy, IVF and multiple embryos transfer. A case report and systematic review of the literature.

Heterotopic pregnancy after bilateral salpingectomy is an extremely rare complication of in vitro fertilisation/embryo transfer cycles. We report a case of a ruptured abdominal pregnancy on the omentum which was the stimulus to conduct the first systematic review on this complication according to 'PRISMA' guidelines (PROSPERO R.No CRD42020134104). PubMed, EMBASE and OpenAIRE databases were systematically reviewed for studies reporting (a) cases or case series of, (b) heterotopic pregnancies after, (c) prior bilateral salpingectomy, and (d) embryo transfer cycles. Twenty-two articles met the selection criteria including, with our case, 28 cases. Based on the results, clinical manifestations and laboratory findings can be unspecific or misleading. Transvaginal ultrasound is the main diagnostic tool as the ectopic foetus is more frequently located in the intramural part of the fallopian tubes, the tubal stump or the ovaries. Laparotomy or laparoscopy are the main treatment options with adequate perinatal outcome.

A woman with disseminated tuberculosis experienced preterm delivery, fallopian tube pregnancy, and delivered successfully following in vitro fertilization: a case report.

BACKGROUND: Disseminated tuberculosis (TB) is a fatal disease resulting from hematogenous dissemination of Mycobacterium tuberculosis. Spontaneous pregnancy rate of women with TB is low; furthermore, live birth, spontaneous abortion or ectopic pregnancy may be the outcomes even if pregnancy occurs. CASE PRESENTATION: We report a case of a woman with disseminated TB who had a series of complications including preterm delivery with congenital TB and infant death of pulmonary TB, fallopian tube pregnancy. She was treated by in vitro fertilization-embryo transfer (IVF-ET), and gave birth to a healthy baby. CONCLUSION: Disseminated TB has a significant impact on female fertility. We should take more active efforts to diagnose and treat this disease in a timely fashion. Moreover, IVF treatment is a feasible approach for an infertile woman after TB.

B cell activation factor (BAFF) induces inflammation in the human fallopian tube leading to tubal pregnancy.

BACKGROUND: Tubal pregnancy is recognized as one of the most common ectopic pregnancy types. Salpingitis may result in tubal pregnancy by causing fallopian tube occlusion and hydrosalpinx. B cell activation factor (BAFF) is a proinflammatory cytokine that helps regulate both innate and adaptive immune responses. Our previous study firstly showed that BAFF immunostaining appeared on the cellular membrane and in the cytoplasm of tubal epithelial cells, and both BAFF protein and mRNA in human inflamed fallopian tubes had higher expression levels than those in normal fallopian tubes. This study aimed to elucidate the association between the expression of BAFF gene and the inflammation in the human fallopian tube leading to tubal pregnancy. METHODS: We examined 70 patients undergoing salpingectomy for salpingitis (n = 35) and tubal pregnancy (n = 35). Twenty patients with benign uterine diseases undergoing complete hysterectomy and salpingectomy were recruited into control group. BAFF mRNA and protein in tissue samples were detected by qPCR and Western blotting methods. Furthermore, serum levels of BAFF, tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 were measured using ELISA kits. RESULTS: We found statistically significantly elevated expressions of BAFF mRNA or protein in whole tissue samples, and serum levels of BAFF, TNF-α and IL-6 in whole blood samples from patients with salpingitis and tubal pregnancy, in comparison to the control group. CONCLUSION: Based on the results, high expression of BAFF gene might induce inflammation in the human fallopian tube, suggesting its possible role in the tubal pregnancy process.

Networks of E-cadherin, ß1 integrin, and focal adhesion kinase in the pathogenesis of tubal pregnancy.

E-cadherin, ß1 integrin, and focal adhesion kinase (FAK) are reported to involved in eutopic implantation by mediating cell adhesion. However, less is documented about their roles in ectopic implantation. This study was undertaken to evaluate the roles and networks of E-cadherin, ß1 integrin, and FAK in tubal pregnancy. A total of 31 Fallopian tube specimens were obtained from tubal pregnant women. Immunohistochemistry and western blot were used to analyze the distributions and levels of E-cadherin, ß1 integrin and phosphorylated-FAK (Pho-FAK) in the Fallopian tube epithelium. Normal Fallopian tube samples derived from non-pregnant women with benign genital diseases were used for comparison. E-cadherin presented in the cytomembrane of tubal epithelial cells and ß1 integrin mainly expressed in the cytoplasm. A lowest-level of E-cadherin was detected in the implantation site (0.63 ± 0.29) when compared with the non-implantation site (0.95 ± 0.37) and the controls (0.89 ± 0.33) (P < 0.05). ß1 integrin, as well as Pho-FAK in the implantation site (0.81 ± 0.35; 0.72 ± 0.24), showed a higher-level than that in the non-implantation site (0.59 ± 0.26; 0.48 ± 0.27) or the control group (0.38 ± 0.19; 0.36 ± 0.25) (p < .05). The decreased E-cadherin and increased ß1 integrin are implicated in tubal pregnancy. The involvement of ß1 integrin maybe depends on ß1 integrin/FAK signaling.

Extrauterine Choriocarcinoma in the Fallopian Tube Following Infertility Treatment: Implications for the Management of Early-Detected Ectopic Pregnancies.

Extrauterine choriocarcinoma in the fallopian tube is very rare and is often diagnosed and treated as an ectopic tubal pregnancy. A 34-year-old woman who initially became pregnant after infertility treatment using ovulation induction with clomiphene citrate and intrauterine insemination was later diagnosed with an extrauterine choriocarcinoma in the left fallopian tube. Because of suspected left ectopic tubal pregnancy based on ultrasonography findings and a high level of ß-human chorionic gonadotropin (ß-hCG; 7054.3 mIU/mL), the patient underwent diagnostic laparoscopy at a gestational age of 6 weeks. Left salpingectomy was performed based on the operative diagnosis of an ectopic tubal pregnancy. No signs of tubal rupture or leakage of contents from the fallopian tube were observed during the operation. Her serum ß-hCG dropped to 10.3 mIU/mL at 15 days postoperatively. Histopathology demonstrated an extrauterine choriocarcinoma in the removed fallopian tube, and the patient was referred to a regional oncologic hospital to receive additional adjuvant chemotherapy. This case indicates that conservative treatment for ectopic pregnancy should be chosen carefully, and that histopathology diagnosis and appropriate ß-hCG monitoring following treatment are important not only to diagnose persistent ectopic pregnancy, but also to rule out the possibility of a tubal choriocarcinoma.

Delayed Detection of Spontaneous Bilateral Tubal Ectopic Pregnancies After Methotrexate Treatment.

BACKGROUND: Bilateral tubal ectopic pregnancies are a rare subset of ectopic pregnancy that can pose a diagnostic dilemma for clinicians. There is no distinct clinical presentation for bilateral tubal ectopic pregnancies, although they are typically associated with assistive reproductive techniques. In addition, there is no single diagnostic feature to help clinicians delineate bilateral tubal ectopic pregnancies from other types of ectopic pregnancy prior to passing the discriminatory zone (such as heterotopic pregnancy or twin ectopic [two gestational sacs in one tube]). Diagnosis is typically made via direct visualization intraoperatively and therefore treatment is usually surgical. CASE REPORT: We present a case of spontaneous bilateral tubal ectopic pregnancies diagnosed 7 days apart via transvaginal ultrasound. The patient presented to the emergency department with pelvic pain on the contralateral side of her previously diagnosed ectopic pregnancy and vaginal spotting. Bilateral adnexal masses were visualized on ultrasound and her serum beta-human chorionic gonadotropin level had a 5.9% decline from day 4 to day 7 after methotrexate administration 7 days prior; gynecology was consulted. The patient was successfully treated with an additional dose of intramuscular methotrexate without any complications. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The implications of this case suggest that diagnosis of bilateral tubal ectopic pregnancies requires clinicians to have a high level of suspicion in any pregnant female with a suspected or known ectopic pregnancy who presents with pelvic pain regardless of prior diagnosis or treatment.

[SUCCESSFUL LAPAROSCOPIC TREATMENT OF HETEROTOPIC PREGNANCY AFTER ICSI / FREEZE EMBRYO TRANSFER - A CASE REPORT.]

The coexistence of extrauterine and intrauterine or haeterotopic pregnancy (HP) is a rare condition with reported incidence of 1 in 8000 to 1 in 30 000 pregnancies in natural conceived pregnancies, but with the widespread application of assisted reproductive technologies (ART) the incidence of HP in women with ART has risen to about 0.09% to 1.00%. We have reported a case of a 36 old woman, pregnant in 9 gestation week, gravidity 2, 0 para, who have achieved a pregnancy after in-vitro fertilization - embryo-transfer of two freeze embryos, developed after an ICSI procedure with donor eggs. The patient attended our clinic because of acute abdominal pain. She was evaluated by trans-vaginal sonography and coexistence of ectopic tubal and intrauterine pregnancy has been confirmed. Emergency laparoscopy was carried out. Left tubal ectopic pregnancy and hemoperitoneum (1200 ml) were diagnosed. Left salpingectomy was performed. At present, the patient is at 24 gestation week and the pregnancy is developing in a proper manner. We report such a case due to the increase of the awareness to the condition and the possibility of a successful treatment by a laparoscopic surgery. Intrauterine pregnancy does not exclude extrauterine pregnancy especially in cases after in-vitro fertilization.

Reduced prevalence of chronic tubal inflammation in tubal pregnancies after levonorgestrel emergency contraception failure.

PURPOSE: The aim of this study was to compare chronic fallopian tubal inflammatory disease and fibrosis between patients with general tubal pregnancy (TP) and TP with levonorgestrel (LNG) emergency contraception (EC) failure. METHODS: We retrospectively studied patients with general TP (n = 79) and TP following LNG-EC failure (n = 81) within the same conception cycle. Information on the gynecological features of each subject was collected. Pelvic inflammatory disease and associated sequelae were assessed by the serum Chlamydia trachomatis (CT) IgG test, laparoscopic evaluation of tubal damage, and histopathological observation of tube tissues. Chi-square and Student's t-tests were employed to determine the difference between the two groups. RESULTS: Compared with general TP, cases of TP following LNG-EC failure subjects were less likely to have a history of previous ectopic pregnancy (5.06% vs. 18.52%, p = 0.009) and adnexal surgery (6.33% vs. 22.22%, p = 0.010). Patients with TP following LNG-EC failure were less likely to have pelvic inflammatory disease and associated sequelae than those with general TP, as revealed by positive reaction to anti-CT IgG (18.18% vs. 35.94%, p = 0.031), assessment of tubal damage (grade I: 5.06% vs. 17.28%; grade II: 2.53% vs. 11.11%; grade III: 1.27% vs. 6.17%; p = 0.001), infiltration of chronic inflammatory cells (10.91% vs. 62.50%, p < 0.001), and positive Masson's staining (7.69% vs. 39.58%; p < 0.001). CONCLUSIONS: Compared with cases of general TP, cases of TP following LNG-EC failure exhibited reduced rates of CT infection, fallopian tubal inflammation, and/or fibrosis.

Unusual ectopic pregnancies: a retrospective analysis of 65 cases.

AIM: The aim of this study was to retrospectively investigate unusual ectopic pregnancies (EP) and compare them with fallopian ones. MATERIAL AND METHODS: A total of 1000 cases of ectopic pregnancies were analyzed, including 65 unusual cases. We discussed distribution, incidence, risk factors, examinations, treatments and prognoses. RESULTS: Ovarian pregnancy was associated with placement of intrauterine device and pelvic inflammatory diseases. Extratubal EP have a high rate of misdiagnosis and presented more serious manifestations. Some unusual EP could be diagnosed by ultrasonography. Ovarian pregnancy was usually manifested as positive culdocentesis. Most of the unusual EP underwent surgery, except some early cervical and corneal pregnancies. CONCLUSION: Although extratubal pregnancies are difficult to diagnose, some histories and auxiliary examinations could make diagnosis easier for clinical physicians. Surgery is still the most effective approach for treatment of unusual EP, while conservative treatment of mifepristone combined with methotrexate or curettage could be used for early diagnosis and treatment of cervical pregnancy.

Live unilateral twin ectopic pregnancy in a fallopian tube remnant after previous ipsilateral salpingectomy.

Ectopic pregnancy remains an important cause of morbidity and mortality in women of childbearing age. We report a case of a unilateral twin ectopic pregnancy in a fallopian tube remnant after previous ipsilateral salpingectomy. The pregnancy was conceived spontaneously and included two live gestations. Although the presentation of this ectopic pregnancy was unique, the patient's risk factors were not. As an example of the type of patient who would benefit from ultrasound screening for ectopic pregnancy, our patient renews the debate around this controversial issue.

Altered innervation of the fallopian tube in ectopic pregnancy.

Three cases of ectopic pregnancy demonstrate different patterns of abnormal innervation in the fallopian tube. In the isthmus of the fallopian tube, we observed either (1) loss of nerves in one or more muscle layers of the fallopian tube or (2) large numbers of abnormal nerve profiles in one or more layers of muscle of the fallopian tube. Each woman had a prior history of one or more surgical terminations of pregnancy at indeterminate gestational ages. A proportion of uterine and tubal nerves pass through the uterosacral ligaments to reach the endometrial-myometrial nerve plexus and terminate as the innervation to the ipsilateral fallopian tube. We propose that injuries to the uterosacral ligaments by excessive traction to the cervix, or over-vigorous curettage to the endometrial-myometrial nerve plexus may account for these neuro-immunohistochemical findings. There were no signs of chronic infection or inflammation in the fallopian tube in any of these cases.

Bilateral ampulary pregnancy after clomifen citrate and intrauterine insemination--a unique case report.

We report a case with bilateral tubal ampullary pregnancy after Clomifen Citrate medication. The first conception in the right tube was after intrauterine insemination or intercourse performed before insemination, while the second one was achieved 10 d after insemination, during the intercourse, in the left tube. This life-threatening and routinely unexpected finding must always have in mind all doctors dealing with patients in emergency care, especially those receiving fertility enhancing drugs. According to the literature data available, this is the first and unique such case in the literature.

[A case of bilateral tubal pregnancy after IVF - ET].

The authors describe a rare case of bilateral tubal pregnancy after IVF. The patient is with secondary infertility. The preceding diagnostic laparoscopy excluded the presence of tubal factor. The results of the spermogram show average to severe form of Oligoasthenozoospermia. Short protocol with GnRH-antagonist was performed and two embryos were transferred on the third day. On the 36th day after the embryo transfer the patient was hospitalized with abdominal pain in the right hypogastric region, clinical and ultrasound indications for hemoperitoneum. Urgent laparotomy was performed followed by salpingectomy dextra due to hemoperitoneum caused by tubal abortion. The examination of the left adnexa reveals uruptured tubal pregnancy in the isthmic part of the tube and the decision for salpingectomy sinistra was taken. Histological examinations confirmed the diagnosis of ectopic pregnancy in both tubes. The frequency of some rare forms and localizations of ectopic as well as heterotopic pregnancies increase after ART.

Mechanism of Human Tubal Ectopic Pregnancy Caused by Cigarette Smoking.

In the past few decades, the smoking rate of women of childbearing age has increased. Epidemiological data has repeatedly shown that smoking women have an increased risk of various reproductive diseases, including ectopic pregnancy (EP), decreased fertility, adverse pregnancy outcomes, and failure of assisted reproduction. The oviduct was the target of cigarette smoke in many in vivo and in vitro studies. The fallopian tube is a well-designed organ. Its function is to collect and transport the ova to the fertilized site and provide a suitable environment for fertilization and early embryonic development. Lastly, the fallopian tube transports the pre-implantation embryo to the uterus. Various biological processes can be studied in the fallopian tubes, making it an excellent model for toxicology. This paper reviews the roles of the fallopian tube in gametes and embryo transportation, and the possible mechanism tobacco smoke contributes to tubal EP. A possible signal pathway might be a model to develop intervention of EP for pregnant women exposed to smoking.

Quadruplet Heterotopic Pregnancy Following In Vitro Fertilization and Embryo Transfer with Laparotomic Removal of Ruptured Twin Tubal Ectopic Pregnancy: A Case Report.

Heterotopic pregnancy (HP) is a rare occurrence in natural pregnancies. However, it can be a life-threatening condition and should be taken into account in all assisted reproductive treatments. Diagnosis and treatment of ectopic pregnancy are challenging issues in patients with HP. Here, we report a rare case of quadruplet HP following an in vitro fertilization-embryo transfer with a viable twin intrauterine pregnancy and ruptured live twin left tubal ectopic pregnancy. A 35-year-old woman (gravida 5, para 1, ectopic pregnancies 2, and abortion 1) was presented to the Emergency Department of Arash Women's Hospital (Tehran, Iran) in March 2021 with abdominal pain. The patient was at six weeks and five days of pregnancy following in vitro fertilization-embryo transfer. Transvaginal sonography (TVS) revealed a live twin intrauterine pregnancy with a ruptured live twin left tubal ectopic pregnancy. The latter was removed via laparotomy to preserve the intrauterine pregnancy. The patient subsequently delivered a female infant at 38 weeks of pregnancy.
