Heterotopic Pregnancy Research Articles

Increasing trends of laparoscopic procedures in non-obstetric surgery during pregnancy over 17 years at a single center: Retrospective case-control study.

This study aimed to examine the diseases requiring surgery during pregnancy, the changes in surgical methods over time, and the characteristics of surgeries performed in different trimesters. A retrospective study conducted at Bundang CHA Hospital between 2006 and 2023 analyzed surgeries performed during pregnancy and compared laparoscopic and open approaches across the three trimesters of pregnancy. Additionally, general (appendicitis, cholecystitis) and gynecologic (heterotopic pregnancy, adnexal torsion) cases were compared. Among 36 181 delivery patients, 101 (0.28%) underwent surgery. The most common conditions were appendicitis (44.6%), cholecystitis (1.9%), heterotopic pregnancy (23.8%), adnexal torsion (27.7%), and cancer (1.9%). The laparoscopic group had a shorter operative time (41.5 ± 19.3 vs. 57.9 ± 33.9 min, p = 0.009) and hospital stay (4.9 ± 2.7 vs. 9.0 ± 9.8 days, p = 0.016) than open surgery group. Heterotopic pregnancy (47.1%) and adnexal torsion (39.2%) were common in the first trimester, whereas appendicitis peaked in the second (80%) and third trimesters (66.7%). The increasing use of assisted reproductive technology (ART) has led to a rise in gynecological patients requiring surgery in the first trimester, resulting in more laparoscopic surgeries during this period. Interestingly, an increase in laparoscopic surgery was also observed in general surgery during the second and third trimesters. Perioperative tocolysis was more frequent (51.1% vs. 3.8%, p < 0.001) and of longer duration (4.6 ± 8.8 vs. 0.1 ± 0.6 days, p = 0.001) after general surgical procedures. Laparoscopic surgery during pregnancy offers several advantages such as shorter operative time and hospital stay. Since 2011, laparoscopic surgery for the entire gestational period has been on the rise.

Clinical outcomes of patients with heterotopic pregnancy after laparoscopic surgery

ObjectiveThis retrospective study aims to analyze laparoscopic surgical management and clinical consequences of patients with heterotopic pregnancy (HP) who underwent in vitro fertilization and embryo transfer (IVF-ET) and laparoscopic surgical management. Material and methodsWe conducted a retrospective analysis of clinical characteristics and pregnancy results of patients with HP who underwent IVF-ET at the Affiliated Maternity and Child Health Care Hospital of Nantong University between January 2013 and December 2022. Results21 patients were diagnosed with HP, with an average diagnostic period of 49.1 ± 11.1 days. 11 cases (52.4 %) exhibited clinical manifestations such as abdominal pain and vaginal hemorrhage before the surgery, while 10 cases (47.6 %) were asymptomatic prior to diagnosis. All patients underwent laparoscopic surgery, resulting in 8 cases of miscarriage postoperatively (6.15 %), and all 13 neonates showed no anomalies at birth. ConclusionLaparoscopic surgery is a safe and effective treatment, and most patients can achieve satisfactory pregnancy outcomes after surgery.

Diagnosis of 42 Cases of Intrauterine Twin Pregnancy Complicated With Ectopic Pregnancy: A Retrospective Cohort Study.

The coexistence of intrauterine twin pregnancy and ectopic pregnancy (EP), known as heterotopic pregnancy, is a rare but potentially life-threatening condition. In this study, we aimed to investigate the pregnancy outcomes in women with intrauterine twin pregnancies complicated with EP after assisted reproductive technology. This retrospective study analyzed the medical records of 42 women diagnosed with intrauterine twin pregnancies complicated with EP via ultrasound or surgery at our hospital between January 2005 and December 2020. We collected data on patient general characteristics, high-risk factors, clinical symptoms, ultrasound features, treatment methods, and pregnancy outcomes. Among the 42 included women, 47.6% (20/42) had a history of tubal surgery, while 52.4% (22/42) and 47.6% (20/42) received the transfer of 2 and 3 embryos, respectively. In terms of treatment, 21.4% (9/42) women received expectant management, whereas 78.6% (33/42) underwent surgical treatment, with laparoscopic surgery accounting for 71.4% (30/42). Tracking the pregnancy outcomes revealed a live birth rate of 81.0% (34/42) and a full-term birth rate of 50.0% (21/42). The preterm birth rate was 31.0% (13/42), with a breakdown of 1 singleton (7.7%, 1/13) and 12 twin births (92.3%, 12/13) among the total 13 premature deliveries. Among the neonates, 33.3% (14/42) were singletons and 47.6% (20/42) twins. Caesarean section accounted for 31 out of 34 deliveries (91.2%). Though the incidence of EP in twin pregnancies has declined in the last decade, early diagnosis and proper management are still crucial for favorable outcomes in twin pregnancies with EP.

A Rare Case of Ruptured Heterotopic Pregnancy after Natural Conception Demanding Immediate Attention

Objective. We present the case of a ruptured heterotopic pregnancy after natural conception and its management during hospi- talization. Case Report. The patient presented to the emergency department of our hospital with symptoms of lower abdominal pain and vaginal blood loss. She reported a confirmed intrauterine pregnancy at 8 weeks’ gestation following natural concep- tion. The patient was admitted to the hospital with the diagnosis of a ruptured ovarian cyst. Due to hemodynamic instability, an urgent exploratory laparotomy was performed. The histological review showed an ectopic fallopian pregnancy, confirming the final diagnosis of an heterotopic pregnancy. Conclusion. Heterotopic pregnancy is a very rare condition, even more so if it happens spontaneously. As a result, it has been insufficiently studied in relation to proper management and timely diagnosis.

Clinical characteristics analysis of heterotopic cervical pregnancy

Objective: To investigate the clinical characteristics of heterotopic cervical pregnancy (HCP). Methods: A retrospective analysis was conducted based on the general clinical data, assisted reproductive technology (ART) data, diagnosis and treatment data, and pregnancy outcomes of 17 patients diagnosed with HCP who received ART at the Reproductive Medicine Center of Peking University Third Hospital from January 2011 to April 2022. Results: The age of 17 HCP patients was (34.2±1.5) years, all of whom occurred after the application of ART; Among them, 11 cases had a history of uterine cavity operation. All 17 patients had vaginal bleeding, with only 1 case accompanied by abdominal pain. The gestational age at the diagnosis of HCP was [6+2 (5+2-6+4)] weeks. Two patients underwent conservative observation and were closely followed up. Both of them had intrauterine pregnancy until full-term and underwent cesarean section; One patient underwent ultrasound-guided cervical pregnancy reduction surgery, resulting in miscarriage due to premature rupture of membranes at 18+1 weeks of intrauterine pregnancy; One patient underwent ultrasound-guided cervical pregnancy reduction surgery, followed by uterine artery embolization, hysteroscopy, removal of cervical pregnancy lesions, and curettage due to excessive bleeding; One patient underwent uterine artery embolization, hysteroscopy, cervical pregnancy lesion clearance, and curettage due to excessive vaginal bleeding; One patient underwent hysteroscopy examination, cervical pregnancy lesion removal surgery, and uterine curettage due to embryo arrest during intrauterine pregnancy; 11 cases underwent ultrasound-guided cervical pregnancy lesion clearance surgery, all of which resulted in live births. Among the 13 delivery patients, 4 cases were premature and 9 cases were full-term; 5 cases of vaginal delivery and 8 cases of cesarean section. Conclusions: The most common clinical manifestation of HCP is vaginal bleeding. Ultrasound guided cervical pregnancy lesion clearance surgery is safe and feasible, and with good pregnancy outcomes.

Diagnosis and management of heterotopic intramural pregnancy after in vitro fertilization: an eight-case series.

To analyze the ultrasound characteristics, clinical management, and pregnancy outcomes of heterotopic intramural pregnancies (HIMPs) after embryo transfer. This was a retrospective observational study of women who were diagnosed with HIMPs. The ultrasound characteristics, clinical treatment, and pregnancy outcomes of patients with HIMPs were evaluated. Eight women with HIMPs were included. Among them, 6 patients were diagnosed by transvaginal sonography, and 2 patients were misdiagnosed with heterotopic interstitial pregnancy. The diagnostic accuracy was 75% (6/8). Five patients with HIMPs were diagnosed at the time of the initial scan (5+6-6+3 weeks). An intramural gestational sac was observed in all 6 patients, and an embryo with cardiac activity was detected in one patient on the follow-up scans. Intrauterine pregnancies (IUPs) were revealed in all 6 patients, and embryo(s) with cardiac activity were observed in 5 patients at the time of the initial diagnosis or later. The patients receiving expectant treatment all presented with bagel signs, while patients with embryos with cardiac activity all underwent surgery. Among the 6 diagnosed women, 1 patient was initially treated medically, 4 were treated expectantly, and 1 was treated surgically. Among the 6 diagnosed patients, the IUPs of 5 patients resulted in live infants. Single ET should be recommended to decrease the possibility of HIMP. An accurate diagnosis of HIMP was reached in most cases by detailed ultrasound early in the first trimester. Most IUPs of HIMPs seem to have good outcomes with timely and proper management. Expectant management might be a possible choice for nonviable intramural pregnancies.

Clinical case of heterotopic pregnancy after in vitro fertilization

Ectopic pregnancy occupies a significant place in the structure of causes of maternal mortality. Timely diagnosis is even more complicated when there is a combination of both uterine and ectopic localization of the ovum. The article describes the clinical observation of heterotopic pregnancy, features of the clinical picture, diagnostic search and treatment strategy. The possibility of preservation of intrauterine pregnancy after surgical removal of a pathologically located second fertilized ovum has been shown. The patient was admitted to the gynecological department with complaints of bleeding from the genital tract against the background of delayed menstruation. An ultrasound examination revealed the presence of dichorionic diamniotic twins, with one fertilized egg localized in the interstitial part of the fallopian tube stump. Surgical removal of the stump with the fertilized egg was performed. The intrauterine pregnancy was preserved. Thus, with timely diagnosis of heterotopic pregnancy and adequate tactics, it is possible to maintain intrauterine pregnancy.

A Rare Phenomenon Spontaneous Heterotropic Pregnancy: Case Report

Abstract Introduction: Heterotopic pregnancy is a rare condition accompanied by intrauterine and ectopic pregnancy. Case: Intrauterine pregnancy and a suspicious ectopic focus were observed in a thirty-seven-year-old patient with no risk factors who presented with menstrual delay. The ectopic pregnancy was successfully removed by surgery to preserve the uterine pregnancy. Discussion: This case report discusses the importance of early diagnosis and management of heterotopic pregnancy to avoid both fetal and maternal morbidity and mortality. Conclusion: It is important to evaluate the adnexia along with the uterus in determining pregnancy in patients presenting with menstrual delay. Additionally, laparoscopy is a reliable option in the treatment of heterotropic pregnancy.

Fortified Pregnancy: A Case Report of Heterotopic Gestation with A Successful Obstetrical Outcome

Heterotopic pregnancy is a rare condition when at least two pregnancies are present simultaneously at different implantation sites. Such cases may lead to devastating outcomes if nor properly handled. The index patient is a 38 year old Gravida 6 Para 4 (4014), who presented with severe hypogastric pain, pallor, amenorrhea with positive pregnancy test and a transvaginal ultrasound showing a strong consideration of heterotopic gestation. Emergency exploratory laparotomy for ruptured tubal pregnancy, Left salpingectomy, and evacuation of hemoperitoneum was done, with a bulbously enlarged left fallopian tube with a 2-cm point of rupture seen intraoperatively

Heterotopic pregnancy: a case report of intrauterine hydatidiform mole with tubal pregnancy.

We herein report a rare case of simultaneous intrauterine molar pregnancy and tubal pregnancy. A woman of childbearing age who had never been pregnant underwent an ultrasound examination 70 days after the onset of menopause. She had a history of ovulation induction. The ultrasound findings suggested a partial hydatidiform mole. She was then pathologically confirmed to have a complete hydatidiform mole after uterine suction dilation and curettage. On postoperative day 4, an ultrasound examination before discharge showed an inhomogeneous mass in the left adnexal region with mild lower abdominal pain. On postoperative day 17, the blood human chorionic gonadotropin level did not drop as expected, and a follow-up examination still indicated a mass in the left adnexal region. We were unable to rule out an ectopic hydatidiform mole. Hysteroscopy with laparoscopic exploration of the left adnexal mass and salpingotomy suggested a diagnosis of intrauterine hydatidiform mole combined with left tubal pregnancy.

A Systematic Review about Cervical Pregnancy and our Experience.

Cervical ectopic pregnancy is a relatively rare type of ectopic pregnancy and has no standardized guidelines for management. This systematic review is based on the collection of case reports, published in PubMed/MEDLINE about the resolution of ectopic cervical pregnancies over the last decade and the presentation of a case managed in our healthcare unit. Studies involving cervical pregnancy in the first trimester with the presence of a viable embryo and β-hCG in the serum below 100.000 mIU/mL were included, while heterotopic pregnancies were excluded. Nineteen articles reporting twenty-three case reports are demonstrated explicitly emphasizing on the management techniques. There is no established approach for the management of this type of ectopic pregnancy. It is important to consider the conservative approaches as first-line treatment in all cases of cervical pregnancy preserving fertility. Minimally invasive methods are also described and preferred as second-line treatment, as reported in our literature review.

Heterotopic pregnancy and the influence of letrozole

Introduction: Heterotopic pregnancy has become increasingly common following increased use of assisted reproductive techniques. We will examine one uncommon instance of a heterotopic pregnancy occurring in the setting of a young woman undergoing letrozole therapy for primary infertility, making it an uncommonly seen case. Case Report: We report a young otherwise healthy female G1P0 at approximately 6 weeks gestation, who was referred from her primary care office to the Emergency Department with progressive abdominal pain that started 12 hours prior and had started to exhibit signs of hemodynamic instability. History was significant for difficulty with conception requiring letrozole treatment. Emergency laparoscopy was performed and confirmed additional ectopic pregnancy in the right fallopian tube with blood originating from the fimbriated end. Evacuation of hemoperitoneum and removal of ectopic pregnancy was completed without complication. She was discharged from the hospital in stable condition. Conclusion: In any woman of reproductive age presenting with lower abdominal pain or abnormal bleeding, there should be a strong suspicion for a pregnancy until confirmed otherwise. These patients may benefit from prompt imaging with pelvic ultrasound to assist in earlier detection of ectopic embryo implantation and, subsequently, earlier intervention. Salpingectomy, ideally via laparoscopic approach, remains the gold standard for diagnosis and treatment of patients with a ruptured ectopic pregnancy in the setting of a heterotopic pregnancy, although surgical intervention is associated with poorer outcomes for the intrauterine pregnancy.

A heterotopic pregnancy at 12 weeks’ pregnancy

Heterotopic pregnancy (HP) represents a rare and complex condition where simultaneous pregnancies occur at different implantation sites, with only one located within the uterine cavity. Typically diagnosed in the first trimester, HP presents diagnostic challenges due to its rarity and varying clinical presentations. Here, we present a unique case of HP diagnosed at Bengkalis Hospital involving a 42-year-old multipara at 12 weeks of gestation. The patient's presentation included regular uterine contractions and upper abdominal pain, with a positive Plano test upon admission. Despite experiencing vaginal bleeding two days prior and an initial refusal of care, further examination revealed a 2.13 cm gestational sac in the intrauterine cavity, consistent with the gestational age. Additionally, free intra-abdominal fluid was observed in the Douglas cavity. Haematological examination indicated a low haemoglobin level of 7.2 g/dl and elevated leukocytes at 16,000. An emergency laparotomy revealed a ruptured right ovarian tube containing a gestational sac, which was managed with hemostasis and a subsequent salpingectomy. The left ovarian tube underwent a tubectomy as a preventive measure. The patient received multiple blood transfusions, leading to an improvement in haemoglobin levels to 10.2 g/dl postoperatively. Following a two-day hospitalisation, the patient was discharged in good general condition. HP cases often necessitate laparotomies for tubal pregnancies, and ultrasound plays a crucial role in diagnosis, especially given its prevalence of 1 in 7000 due to assisted reproduction. Treatment typically involves laparoscopic or laparotomic intervention, highlighting the multidisciplinary approach required for managing this rare condition.

Surgical management of cornual heterotopic using intraoperative sonography depth resection guidance: case report

Heterotopic pregnancy is an uncommon phenomenon in which an ectopic and intrauterine pregnancy coexist. This condition can be life-threatening and poses a significant therapeutic challenge. Here we describe management of a heterotopic pregnancy with the ectopic pregnancy located in the right cornua. Resection of the ectopic pregnancy was performed via open laparotomy with intraoperative sonography. A sonography guided approach may optimize resection depth while secondarily allowing monitoring of the intrauterine pregnancy and prevention of disruption in cases in which the gestational sacs are in close proximity. After resection, the course of the pregnancy was uncomplicated, and a healthy baby was delivered via planned cesarean delivery at 36 weeks. While the optimal management of heterotopic pregnancies is often individualized, prompt diagnosis and treatment can result in favorable outcomes. The use of ultrasound intraoperatively allows for more precise resection depth, and which may lead to improved outcomes including increased intrauterine fetal survival rates and decreased myometrial scarring.

Combined hysteroscopic Bigatti shaver (IBS) and resectoscope removal of a heterotopic cesarean scar pregnancy in the first trimester

To report a case of heterotopic cesarean scar pregnancy reduction using a combined hysteroscopic integrated Bigatti shaver (IBS) and resectoscope with the preservation of a normal gestational sac in the uterine cavity under simultaneous transabdominal ultrasound guidance. Video article. University-affiliated hospital. A 30-year-old woman, G5P2A2L2, with two previous cesarean deliveries and a history of fertility problems, was admitted with a heterotopic cesarean scar pregnancy at 7+2 gestational weeks. Ultrasound examination showed a dichorionic diamniotic pregnancy. The first gestational sac (1.7 × 1.7 × 0.6 cm) was located in the previous hysterotomy scars, with a thin layer of myometriummeasuring 0.2 cm in thickness and a rich blood supply. The second chorionic sac (2.8 × 2.4 × 1.8 cm) was observed at the uterine fundus. Normal cardiac activity and yolk sacs were observed in both gestational sacs. The couple strongly desired to preserve the intrauterine pregnancy. After Institutional Review Board approval was obtained, a hysteroscopic IBS combined with a bipolar resectoscope was used to remove the heterotopic cesarean scar pregnancy while preserving the intrauterine gestational sac under simultaneous transabdominal ultrasound guidance. The heterotopic cesarean scar pregnancy was completely resected using hysteroscopy, and the gestational sac in the uterine cavity was successfully preserved. Trophoblastic tissue was confirmed using histopathological examination. The patient had an unremarkable postoperative recovery. Subsequent serial ultrasonography confirmed a single ongoing pregnancy with normal growth parameters and a normal placental site. The inability of an IBS to perform coagulation can be offset by its combination with the bipolar resectoscope. Hysteroscopic IBS combined with resectoscope to remove a heterotopic cesarean scar pregnancy offers a short operation time and minimum blood loss. It could be an optimized approach for the management of heterotopic cesarean scar pregnancy in the first trimester when an intrauterine pregnancy needs to be preserved.

Laparoscopic removal of heterotopic cesarean scar pregnancy

ObjectiveTo present the laparoscopic management of heterotopic cesarean scar pregnancy and discuss other treatment options. DesignSurgical video article. The Institutional Ethics Committee approved the video reproduction. SettingTertiary referral university hospital PatientA 29-year-old woman with spontaneous heterotopic cesarean scar pregnancy presented for vaginal spotting. Ultrasound revealed two gestational sacs at 7 weeks and 6 days of gestation with fetal cardiac activity. One sac was in a normal intrauterine location and the other in a previous cesarean section scar. InterventionsScar pregnancy was excised laparoscopically while preserving intrauterine pregnancy. No additional measures were taken to reduce bleeding. The bladder was filled with 150 cc isotonic to determine its boundaries. The peritoneum was dissected away from the cervix. After removing the ectopic pregnancy material, the myometrial defect was excised. The uterine wall was closed in three layers using 2-0 V-LocTM sutures. Main outcome measuresOngoing intrauterine pregnancy after laparoscopic removal of cesarean scar pregnancy and term delivery. ResultsThe procedure was completed in 67 min. Total blood loss was <100 cc. Ongoing pregnancy follow-up was uneventful. Delivery was planned for the 37th-38th weeks. Although instructed to visit immediately after experiencing pain, the patient arrived after the 38th week and reported having pain for 2 days. During cesarean section, a rupture was observed at the previous incision site, which was fortunately incomplete. A healthy male baby (weight, 3210 g; Apgar score, 9/10) was delivered. ConclusionsThe most common approach for heterotopic scar pregnancy is embryo reduction with potassium chloride injection. However, the mass persists in the scar area, resulting in complications associated with excessive bleeding during cesarean section in approximately half cases. Moreover, almost all published cases of embryo reduction resulted in premature births before week 36. Considering the present case, laparoscopic surgery may be appropriate for managing heterotopic cesarean scar pregnancy by preserving intrauterine pregnancy.
