RESUMEN

BACKGROUND: Ectopic pregnancy associated with appendicitis is rare, with very few cases reported in the literature. It is unclear if appendicitis is coincidentally associated with ectopic pregnancy or a possible risk factor for the development of ectopic pregnancy. Ruptured ectopic pregnancy has also been postulated as a possible risk factor leading to appendicitis because of the probable inflammatory reaction involving the adjacent appendix. METHODS: We present a 34-year-old female who presented with right lower abdominal pain and bleeding per vaginam, three weeks after in-vitro fertilization and embryo transfer. RESULTS: A diagnosis of ectopic pregnancy was made following a positive ß-HCG and empty uterine cavity on pelvic ultrasound scan. Intraoperatively, the appendix was noted to be inflammed and it was removed and confirmed on histology examination as acute appendicitis. CONCLUSION: Ruptured ectopic pregnancy associated with acute appendicitis is rare, with few cases reported in the literature. We recommend an examination for other possible differentials of ruptured ectopic pregnancy like appendicitis during surgery for ectopic pregnancy on the right side.

CONTEXTE: L'association de la grossesse extra-utérine avec l'appendicite est rare, avec très peu de cas rapportés dans la littérature. Il n'est pas clair si l'appendicite est associée de manière fortuite à la grossesse extra-utérine ou si elle constitue un facteur de risque possible pour le développement de celle-ci. On a également postulé que la grossesse extra-utérine rompue pourrait être un facteur de risque conduisant à l'appendicite en raison de la probable réaction inflammatoire impliquant l'appendice adjacent. MÉTHODES: Nous présentons le cas d'une femme de 34 ans qui s'est présentée avec une douleur abdominale basse à droite et des saignements vaginaux, trois semaines après une fécondation in vitro et un transfert d'embryon. RÉSULTATS: Un diagnostic de grossesse extra-utérine a été posé suite à un test de ß-HCG positif et une cavité utérine vide à l'échographie pelvienne. En peropératoire, l'appendice a été noté comme étant inflammé et a été retiré. L'examen histologique a confirmé une appendicite aiguë. CONCLUSION: La grossesse extra-utérine rompue associée à une appendicite aiguë est rare, avec quelques cas rapportés dans la littérature. Nous recommandons un examen pour d'autres diagnostics différentiels possibles de la grossesse extra-utérine rompue, comme l'appendicite, lors de la chirurgie pour grossesse extra-utérine du côté droit. MOTS CLÉS: Grossesse extra-utérine hémorragique, Appendicite, Fécondation in vitro, Laparotomie.

RESUMEN

The rate of cesarean section (CS) for delivery has increased internationally, reaching 50% in some countries. Abnormal implantation of a new pregnancy at the site of the prior hysterotomy is an important complication because of the risks of hemorrhage, uterine rupture, and progression to placenta accreta spectrum (PAS), a condition with high morbidity with potential for catastrophic obstetric hemorrhage, maternal and fetal mortality, and loss of fertility. Cesarean scar ectopic pregnancy (CSEP) is the recommended term to describe these pregnancies, which are recognized on the basis of the sac implantation site, growth pattern, and associated abnormal perfusion. The true incidence of CSEP is unknown because the condition is likely underdiagnosed and underreported. The 2022 Society for Maternal-Fetal Medicine consult series notes that severe maternal morbidity and mortality are linked to difficulty in making the diagnosis of CSEP. The authors review the signs of CSEP at imaging, some pitfalls that may lead to delayed or missed diagnosis, and the consequences thereof. CSEPs must be differentiated from low implantation of a normal pregnancy, cervical ectopic pregnancy, and evolving pregnancy loss. Early recognition allows prompt and safe treatment that is usually surgical. Early treatment results in decreased health care costs, a shorter hospital stay, preservation of fertility, and prevention of iatrogenic preterm delivery, which is typical in cases that progress to PAS. Hysterectomy has serious negative psychologic consequences for patients of childbearing age; early diagnosis and prompt treatment of CSEP can prevent this often-ignored complication. ©RSNA, 2024 Supplemental material is available for this article.

RESUMEN

OBJECTIVE: Existing evidence of the relationship between induced abortion and ectopic pregnancy has not been assessed rigorously. This systematic review provides a comprehensive evaluation to examine whether induced abortion (IA) can increase the rate of ectopic pregnancy (EP). METHODS: We searched PubMed, EMBASE, Web of Science, Cochrane, CNKI, WanFang, and Sinomed databases since their inception until February 2023. Eligibility criteria included case-control studies and cohort studies that analyzed induced abortion associated with ectopic pregnancy. Data analyses were conducted by using R-studio Version 1.1.383 software. RESULTS: A total of 33 case-control studies and 7 cohort studies involving 132,926 participants were included. In case-control studies, there was a significant association between induced abortion and ectopic pregnancy by using single-factor analysis data (OR = 2.32, 95% CI = 1.81-2.98). Subgroup analysis by region suggested no statistical significance in the Americas (OR = 1.15, 95% CI = 0.92-1.43) and Eastern Mediterranean (OR = 3.64, 95% CI = 0.88-15.18). The relationship was significant by using multiple regression analysis data (OR = 1.97, 95% CI = 1.38-2.80). In cohort studies, statistical significance was found (OR = 1.42, 95% CI = 1.001-2.018) after omitting one study in sensitivity analysis. The combined results of the two types of studies suggested that induced abortion would increase the risk of ectopic pregnancy to some degree, but the conclusion needs to be considered with caution. CONCLUSION: This study indicated that IA could increase the risk of EP to some degree and the times of IA had a negative impact on the risk. Safe abortion and avoiding repeat abortion due to unintended pregnancy could protect women's fertility.

RESUMEN

BACKGROUND: To investigate factors associated with different reproductive outcomes in patients with Caesarean scar pregnancies (CSPs). METHODS: Between May 2017 and July 2022, 549 patients underwent ultrasound-guided uterine aspiration and laparoscopic scar repair at the Gynaecology Department of Hubei Maternal and Child Health Hospital. Ultrasound-guided uterine aspiration was performed in patients with type I and II CSPs, and laparoscopic scar repair was performed in patients with type III CSP. The reproductive outcomes of 100 patients with fertility needs were followed up and compared between the groups. RESULTS: Of 100 patients, 43% had live births (43/100), 19% had abortions (19/100), 38% had secondary infertility (38/100), 15% had recurrent CSPs (RCSPs) (15/100). The reproductive outcomes of patients with CSPs after surgical treatment were not correlated with age, body mass index, time of gestation, yields, abortions, Caesarean sections, length of hospital stay, weeks of menopause during treatment, maximum diameter of the gestational sac, thickness of the remaining muscle layer of the uterine scar, type of CSP, surgical method, uterine artery embolisation during treatment, major bleeding, or presence of uterine adhesions after surgery. Abortion after treatment was the only risk factor affecting RCSPs (odds ratio 11.25, 95% confidence interval, 3.302-38.325; P < 0.01) and it had a certain predictive value for RCSP occurrence (area under the curve, 0.741). CONCLUSIONS: The recurrence probability of CSPs was low, and women with childbearing intentions after CSPs should be encouraged to become pregnant again. Abortion after CSP is a risk factor for RCSP. No significant difference in reproductive outcomes was observed between the patients who underwent ultrasound-guided uterine aspiration and those who underwent laparoscopic scar repair for CSP.

RESUMEN

Smoking during pregnancy is associated with negative reproductive outcome. Less is known about the impact of smoking or previous smoking in women with recurrent pregnancy loss (RPL) which this study aimed to investigate. We included all women <42 years (n=2829) referred to a RPL unit at Copenhagen University Hospital between January 2000 and December 2021 in the cohort with follow-up until June 2022. Patients were categorized as 'smokers at time of referral', 'never-smokers' or 'former smokers'. The main outcomes were pregnancy history prior to referral, prospective pregnancy rate, live birth rate, rates of ectopic pregnancy, and stillbirth. At referral, smokers (n=373) were on average 2.0 years younger (P<0.001) and had experienced significantly more pregnancy losses (P<0.001), and stillbirths (P=0.01) compared to never-smokers (n=2100). Former smokers had a higher risk of stillbirth prior to referral compared to never-smokers but no differences in pregnancy rate or other outcomes. Prospective pregnancy rates were lower for smokers compared with never-smokers (71.8% vs. 77.5%, P=0.02). Live birth rate was 58.0% for the 243 women who smoked at referral compared to 61.4% for the 1488 never-smokers (P=0.32). Stillbirth and ectopic pregnancies were significantly more common for smokers (2.8% vs. 0.4%, P=0.01; 6.0% vs. 2.0%, P<0.008). Women with RPL who smoked at referral were referred younger with a higher number of previous pregnancy losses and stillbirths compared with never-smokers. Fewer smokers achieved a pregnancy after referral but those who did had a similar live birth rate compared to never-smokers, although stillbirths and ectopic pregnancies were more common.

RESUMEN

OBJECTIVE: To present the laparoscopic management of heterotopic cesarean scar pregnancy and discuss other treatment options. DESIGN: Surgical video article. The Institutional Ethics Committee approved the video reproduction. SETTING: Tertiary referral to a university hospital. PATIENT: A 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 (IU) location, and the other was in a previous cesarean section scar. INTERVENTIONS: Scar pregnancy was excised laparoscopically, preserving IU 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-Loc sutures. MAIN OUTCOME MEASURES: Ongoing IU pregnancy after laparoscopic removal of cesarean scar pregnancy and term delivery. RESULTS: The procedure was completed in 67 minutes. Total blood loss was <100 cc. The 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 the cesarean section, a rupture was observed at the previous incision site, which was fortunately incomplete. A healthy male infant (weight, 3,210 g; Apgar score, 9/10) was delivered. CONCLUSIONS: The 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 a cesarean section in approximately half of 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 IU pregnancy.

RESUMEN

OBJECTIVE: 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. DESIGN: Video article. SETTING: University-affiliated hospital. PATIENT: 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 myometrium measuring 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. INTERVENTION(S): 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. MAIN OUTCOME MEASURE(S): The heterotopic cesarean scar pregnancy was completely resected using hysteroscopy, and the gestational sac in the uterine cavity was successfully preserved. RESULT(S): 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. CONCLUSION(S): 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.

RESUMEN

OBJECTIVE: To describe an effective two-step surgical approach for the management of cesarean scar ectopic pregnancies (CSEPs). CSEPs occur at an estimated frequency of 1 in 1,800 pregnancies, constituting approximately 6% of ectopic pregnancies in women with a history of prior cesarean delivery [1, 2]. Despite numerous recommended therapeutic approaches, the most effective treatment strategy remains uncertain [3]. DESIGN: We present an innovative double-step technique for the management of a patient with a CSEP involving hysteroscopic subchorionic injection of methotrexate (MTX), followed by laparoscopic resection of the residual gestational sac and simultaneous repair of the uterine defect. SETTING: Academic tertiary hospital. PATIENT: A 34-year-old G2P1001 with a history of prior cesarean section presented at 10 weeks of gestation. Ultrasound revealed a gestational sac within the niche of the previous cesarean scar, confirming the diagnosis of a CSEP. The patient included in this video gave consent for publication of the video and posting of the video online, including on social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, and Scopus, among others), and other applicable sites. INTERVENTION: The initial treatment involved hysteroscopic administration of MTX within the placental intervillous spaces, ensuring precise medication delivery. The administered dose of MTX was 1 mg/kg. Following the normalization of beta-human chorionic gonadotrophin (ß-hCG) levels, laparoscopic resection of the remaining gestational sac and reconstruction of the uterine wall defect were performed. MAIN OUTCOME MEASURES: We have implemented a management strategy focusing on ectopic pregnancy removal and addressing defect revision. The hysteroscopic approach allows for a clear assessment of the ectopic pregnancy and facilitates precise MTX administration, enhancing its effectiveness by increasing drug concentration within the placental intervillous space. Delaying surgical repair until after the ß-hCG levels have decreased reduces the risk of excessive bleeding during the procedure, as lower ß-hCG levels are associated with reduced vascularity at the ectopic site. Subsequent laparoscopic resection allows for complete removal of the remaining products of conception and repair of the defect, preserving the uterus and restoring normal anatomy. Compared to other surgical approaches, our two-step approach enables a more precise evaluation of placental implantation, making it a highly effective surgical method. RESULTS: We successfully managed a CSEP using a double-step technique. This involved hysteroscopic injection of subchorionic MTX, followed by laparoscopic resection of the residual gestational sac. Concurrently, we repaired the uterine defect. Both procedures were performed in an outpatient setting without complications detected during or after treatment. At the follow-up visit, the patient reported good health, and subsequent ultrasound confirmed an empty isthmocele. CONCLUSION: This sequential hysteroscopic and laparoscopic approach represents a definitive and effective minimally invasive surgical option for the treatment of CSEP.

RESUMEN

RATIONALE: The overall pregnancy rate in individuals with an intrauterine device (IUD) for contraception is <1%. If pregnancy occurs while an IUD is in place, there is a higher risk of an ectopic pregnancy. We report the case of a woman with an IUD who was 7 weeks pregnant and experienced a spontaneous abortion 1 week later. PATIENT CONCERN: A 32-year-old woman presented to our outpatient department with intermittent vaginal staining for several days. DIAGNOSES: She was 7 weeks pregnant and had an IUD in place for over 4 years. A vaginal examination revealed no vaginal bleeding and no blood clots; however, a parous cervix was observed. The IUD string was not visible. Transvaginal ultrasonography revealed a gestational sac in the uterine cavity, with a fetal pole and a crown-rump length of 11.4 mm. The fetal heart rate was 159 beats/min. The IUD was located in the retroplacental region. The bilateral adnexa appeared normal (right ovary, 2.9 cm; left ovary, 2.5 cm). The patient was diagnosed with an intrauterine pregnancy with an IUD in place and threatened abortion. INTERVENTIONS: Attempts to remove the IUD were abandoned due to its location, and conservative treatment was initiated with Utrogestan (100 mg) administered 3 times a day for 1 week. Bed rest was advised. OUTCOMES: Unfortunately, she experienced a complete abortion 1 week later. LESSONS: The novelty of this case report lies in the rare occurrence of an intrauterine pregnancy with a long-term IUD in place, the challenges posed by the IUD's specific location, and the complex management of threatened abortion in this context. Our case highlights the diagnostic management approach for intrauterine pregnancy with an IUD in place. Furthermore, it explores the impact of IUD location on pregnancy prognosis.

RESUMEN

OBJECTIVE: We investigated the efficacy of a combination of laparoscopy and bilateral uterine artery occlusion (BUAO) for the treatment of type II cesarean scar pregnancy (CSP). METHODS: Patients with type II CSP underwent laparoscopy + bilateral uterine artery embolization (control group) or laparoscopy + BUAO (study group). Data regarding the duration of surgery, intraoperative hemorrhage, postoperative complications, the duration of the hospital stay, and the costs of hospitalization were retrospectively collected. One year later, the time to the return of the ß-human chorionic gonadotropin (ß-hCG) concentration to normal and to the return of menstruation were compared. RESULTS: The duration of surgery, time to the return of menstruation, and incidence of postoperative complications in the study group were significantly less than in the control group, but there was no significant difference in the time for ß-hCG to return to normal or the volume of intraoperative hemorrhage. The duration of hospitalization and costs for the control group were higher than those for the study group. CONCLUSION: Laparoscopy in combination with BUAO is associated with minimal trauma, rapid recovery, a short duration of surgery, low cost of hospitalization, and a low postoperative complication rate. Thus, it represents a useful new surgical treatment for type II CSP.

RESUMEN

In this retrospective study conducted at Sichuan Jinxin Xinan Women and Children's Hospital spanning January 2015 to December 2021, our objective was to investigate the impact of embryo cryopreservation duration on outcomes in frozen embryo transfer. Participants, totaling 47,006 cycles, were classified into 3 groups based on cryopreservation duration: ≤1 year (Group 1), 1 to 6 years (Group 2), and ≥6 years (Group 3). Employing various statistical analyses, including 1-way ANOVA, Kruskal-Wallis test, chi-square test, and a generalized estimating equation model, we rigorously adjusted for confounding factors. Primary outcomes encompassed clinical pregnancy rate and Live Birth Rate (LBR), while secondary outcomes included biochemical pregnancy rate, multiple pregnancy rate, ectopic pregnancy rate, early and late miscarriage rates, preterm birth rate, neonatal birth weight, weeks at birth, and newborn sex. Patient distribution across cryopreservation duration groups was as follows: Group 1 (40,461 cycles), Group 2 (6337 cycles), and Group 3 (208 cycles). Postcontrolling for confounding factors, Group 1 exhibited a decreased likelihood of achieving biochemical pregnancy rate, clinical pregnancy rate, and LBR (OR < 1, aOR < 1, P < .05). Furthermore, an elevated incidence of ectopic pregnancy was observed (OR > 1, aOR > 1), notably significant after 6 years of freezing time [aOR = 4.141, 95% confidence intervals (1.013-16.921), P = .05]. Cryopreservation exceeding 1 year was associated with an increased risk of early miscarriage and preterm birth (OR > 1, aOR > 1). No statistically significant differences were observed in birth weight or sex between groups. However, male infant birth rates were consistently higher than those of female infants across all groups. In conclusion, favorable pregnancy outcomes align with embryo cryopreservation durations within 1 year, while freezing for more than 1 year may diminish clinical pregnancy and LBRs, concurrently elevating the risk of ectopic pregnancy and preterm birth.

RESUMEN

Background and Objectives: Cesarean scar pregnancy (CSP) represents a type of ectopic pregnancy in which the embryo implants inside the scar of a previous cesarean section. This condition can lead to maternal morbidity and mortality. The best therapeutic approach in terms of clinical effectiveness and patient safety for CSP has not been described yet, although different therapeutic strategies are currently available. The purpose of the present study was to analyze the success rate of two different treatments in a single institution. Materials and Methods: A retrospective study was performed among patients diagnosed with CSP at the Gynecology and Obstetrics Department of the "Cannizzaro" Hospital in Catania (University of Enna-Italy) from January 2016 to December 2022. The diagnosis was made by 2D/3D transvaginal ultrasound, following Timor-Tritsch criteria. Two treatment strategies were performed: local and systemic methotrexate (MTX) injection and uterine artery embolization (UAE) with subsequent dilatation and curettage (D&C). All treated women underwent subsequent clinical and sonographic follow-up. Complete recovery was defined as the reduction of ß-HCG values until it was undetectable and the disappearance of the mass in the uterine scar on ultrasound. Results: Nineteen patients were included; nine were in the MTX group and ten were in the UAE + D&C group. No significant differences were found between the two groups in terms of clinical parameters. Treatment was successful in 4 of 10 (44%) patients in the MTX group and 10 of 10 (100%) in the UAE + D&C group (p = 0.01); the length of hospital stay was significantly shorter in the latter group (p < 0.0001). Conclusions: In our experience, administration of MTX is not recommended as the primary treatment or pre-treatment. Dilatation and curettage after uterine artery embolization are better than methotrexate injection for the treatment of cesarean scar pregnancy in a single-institution series in terms of complete recovery and length of hospital stay.

RESUMEN

BACKGROUND: Cesarean scar pregnancy (CSP) refers to the phenomenon in which a fertilized egg implants and develops in the scar of the uterus in a woman with a history of cesarean section. OBJECTIVE: The study aimed to explore the differential diagnostic value of two-dimensional ultrasound (2D US) combined with three-dimensional ultrasound (3D US) for CSP. METHODS: Clinical data of 89 patients with CSP admitted to our hospital from January 2022 to January 2023 were retrospectively analyzed. Of them, 65 patients met the inclusion criteria. Patients underwent 2D US, 3D US, and combined 2D and 3D US imaging. Using the clinical pathological diagnosis as the "gold standard", the differential diagnostic value of 2D US, 3D US, and 2D US combined with 3D US for CSP was compared. RESULTS: The detection rate of CSP using a combined 2D US and 3D US was 98.46%, which was higher than 84.62% and 89.23% achieved with 2D US and 3D US alone, respectively (P<0.05). The pathological results showed that among 65 patients, CSP type I accounted for 24.62%, type II accounted for 55.38%, and type III accounted for 20.00%. The coincidence rate of 2D US combined with 3D US was 98.46%, which was higher than that of 2D US (83.08%) and 3D US 89.23%) alone (P<0.05). The accuracy, specificity, and sensitivity of 2D US combined with 3D US in diagnosing CSP were higher compared to the two methods alone (P<0.05). CONCLUSION: The combination of 2D US and 3D US can accurately detect and classify CSP, further improving diagnostic efficiency.

RESUMEN

OBJECTIVES: Cesarean scar pregnancy (CSP) is a rare dangerous condition with still no consensus on standard treatment. Suction curettage has been used as the first-line treatment for CSP with controversial outcomes. This study evaluates efficacy of ultrasound-guided suction curettage (UGSC) followed by cervical-isthmic placement of silicon semirigid three-way foley catheter. MATERIALS AND METHODS: This study included 24 women with CSP. Preoperative ultrasound study was conducted. UGSC followed by placement of catheter was performed in all patients. The success rate and incidence of major complication, surgical time and hospital stay were recorded. RESULTS: The success rate of UGSC followed by placement of foley catheter was 100 %, effectively reduced major complications and none of the patients had a blood loss higher than 900 ml. Median hospital stay was 2 days and median foley stay was 1 day. Surgery had limited last with a median of 17 min. CONCLUSION: UGSC followed by foley placement is a safe effective treatment for CSP with a clinical resolution of 100 %. The catheter is easy to place under ultrasound guidance and prevents bleeding, reducing major procedures to solve the bleeding. Suction curettage in CSP treatment should be performed under ultrasound guidance and followed by cervical-isthmic placement of foley balloon.

RESUMEN

BACKGROUND: Cesarean scar pregnancy (CSP) is a long-term complication of cesarean section characterized by the localization of a subsequent gestational sac within the scar area or niche developed as a result of a previous cesarean section. Its incidence has increased substantially because of the high global cesarean section rate in recent decades. Several surgical and drug treatments exist for this condition; however, there is currently no optimal treatment. This study compared the effectiveness of direct hysteroscopic removal of the gestational tissue and hysteroscopy combined with vacuum suction for the treatment of CSP. METHODS: From 2017 to 2023, 521 patients were diagnosed with CSP at our hospital. Of these patients, 45 underwent hysteroscopy. Among them, 28 underwent direct hysteroscopic removal (hysteroscopic removal group) and 17 underwent hysteroscopy combined with vacuum suction (hysteroscopic suction group). The clinical characteristics and outcomes of the hysteroscopic removal group and hysteroscopic suction group were analyzed. RESULTS: Among the 45 patients, the amount of bleeding and hospitalization cost were significantly higher in the hysteroscopic removal group than in the hysteroscopic suction group (33.8 mL vs. 9.9 mL, P < 0.001; and 8744.0 yuan vs. 5473.8 yuan, P < 0.001; respectively). The operation time and duration of hospitalization were significantly longer in the hysteroscopic removal group than in the hysteroscopic suction group (61.4 min vs. 28.2 min, P < 0.001; and 3.8 days vs. 2.4 days, P = 0.026; respectively). Three patients in the hysteroscopic removal group had uterine perforation and received laparoscopic repair during operation. No complications occurred in the hysteroscopic suction group. One patient in the hysteroscopic removal group received ultrasound-guided suction curettage due to postoperative moderate vaginal bleeding, and one patient in the hysteroscopic suction group received ultrasound-guided suction curettage due to postoperative gestational residue and elevated serum beta-human chorionic gonadotropin levels. Reproductive function was preserved in all patients. CONCLUSIONS: Hysteroscopy is an effective method for treating CSP. Compared with direct hysteroscopic removal, hysteroscopy combined with vacuum suction is more suitable for CSP. However, multicenter prospective studies with large sample sizes are required for verification of these findings.

RESUMEN

OBJECTIVE: To compare the application of sequential embryo transfer, cleavage embryo transfer, and blastocyst transfer combined with intrauterine perfusion in frozen-thawed embryo transfer cycles in patients with recurrent implantation failure to provide a reference for reproductive clinicians. METHODS: The 166 patients who underwent frozen-thawed embryo transfer due to recurrent implantation failure in the reproductive center from January 2021 to March 2022 were retrospectively analyzed. According to the different embryos transferred, they were divided into cleavage embryo transfer groups (72 cases in Group A), blastocyst transfer group (29 cases in Group B), and sequential transfer group (65 cases in Group C). All three groups were treated with intrauterine perfusion 5 days before embryo transfer. The general data and clinical pregnancy outcome indicators, such as embryo implantation rate, clinical pregnancy rate, ongoing pregnancy rate, live birth rate, twin rate, were compared among the three groups. RESULTS: The embryo implantation rate (53.1%), clinical pregnancy rate (76.9%), ongoing pregnancy rate (67.7%) and live birth rate(66.15%) in the sequential transfer group were significantly higher than those in the other two groups (P < 0.05), and the ectopic pregnancy rate was lower in the sequential transfer group. CONCLUSION: Sequential transfer combined with intrauterine perfusion partially improves clinical pregnancy outcomes and reduces the risk of ectopic pregnancy in frozen embryo cycle transfers in patients with recurrent implantation failure, which may be a favourable transfer reference strategy for patients with recurrent implantation failure.

RESUMEN

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.

RESUMEN

PURPOSE: Acknowledging the associated risk factors may have a positive impact on reducing the incidence of ectopic pregnancy (EP). In recent years, body mass index (BMI) has been mentioned in research. However, few studies are available and controversial on the relationship between EP and BMI. METHODS: We retrospectively studied the EP women as a case group and the deliveries as a control group in the central hospital of Wuhan during 2017 ~ 2021. χ2 test of variables associated with ectopic pregnancy was performed to find differences. Univariate and multivariate binary logistic regression analysis was conducted to analyze the association of the variables of age, parity, history of induced abortion, history of ectopic pregnancy, history of spontaneous abortion, history of appendectomy surgery and BMI (< 18.5 kg/m2, 18.5 ~ 24.9 kg/m2, 25 kg/m2 ~ 29.9 kg/m2, ≥ 30 kg /m2) with EP. RESULTS: They were 659 EP and 1460 deliveries. The variables of age, parity, history of induced abortion, history of ectopic pregnancy and BMI were different significantly(P < 0.05). Multivariate analysis showed that the variables of age > 35 years old [(OR (Odds Ratio), 5.415; 95%CI (Confidence Interval), 4.006 ~ 7.320, P < 0.001], history of ectopic pregnancy (OR, 3.944; 95%CI, 2.405 ~ 6.467; P < 0.001), history of induced abortion(OR, 3.365; 95%CI, 2.724 ~ 4.158, P < 0.001) and low BMI (< 18.5 kg/m2) (OR, 1.929; 95%CI, 1.416 ~ 2.628, P < 0.001])increased the risk of EP. CONCLUSION: The history of ectopic pregnancy, history of induced abortion and age > 35 years old were the risk factors with EP. In addition to these traditional factors, we found low BMI (< 18.5 kg/m2) with women may increase the risk to EP.
