Objective: To evaluate whether there were differences in the presentation of patients with tubal ectopic pregnancy (EP) during the first year of the COVID-19 pandemic., Methods: We performed a retrospective cohort study of all cases of tubal EP between March 2019 and March 2020 (pre-pandemic) and between March 2020 and March 2021 (pandemic). We compared between these two groups the risk factors, clinical characteristics, laboratory data, sonographic aspects, treatment applied and complications., Results: We had 150 EP diagnoses during the two years studied, of which 135 were tubal EP. Of these, 65 were included in the pre-pandemic and 70 in the pandemic period. The prevalence of lower abdominal pain was significantly higher in the pandemic compared to the pre-pandemic period (91.4% vs. 78.1%, p=0.031). There was no significant difference in shock index, initial beta-hCG level, hemoglobin level at diagnosis, days of menstrual delay, aspect of the adnexal mass, amount of free fluid on ultrasound, and intact or ruptured presentation between the groups. Expectant management was significantly higher during the pandemic period (40.0% vs. 18.5%, p=0.008), surgical management was lower during the pandemic period (47.1% vs. 67.7%, p=0.023), and number of days hospitalized was lower in the pandemic period (1.3 vs. 2.0 days, p=0.003)., Conclusion: We did not observe a significant difference in patient history, laboratory and ultrasound characteristics. Abdominal pain was more common during the pandemic period. Regarding treatment, we observed a significant increase in expectant and a decrease in surgical cases during the pandemic period., Competing Interests: Conflicts to interest: none to declare., (© 2024.

Objective: We aimed to assess the impact of the coronavirus disease 2019 pandemic on the clinical presentation of tubal ectopic pregnancies., Methods: This retrospective cohort study was conducted at a tertiary center and included 76 cases of tubal ectopic pregnancies. The study period was divided into two groups: the pre-coronavirus disease group (January 2018 to February 2020, Group 1; n=47, 61.8%) and the coronavirus disease group (March 2020 to February 2022, Group 2; n=29, 38.2%). Subgroup analysis was also performed for tubal ruptured ectopic pregnancies as Group 1 (n=15, 62.5%) and Group 2 (n=9, 37.5%)., Results: No statistically significant differences were observed between the pre-coronavirus disease and coronavirus disease groups in terms of demographic characteristics. Although the serum beta-human chorionic gonadotropin level was found to be higher in Group 2, the difference was not statistically significant (p=0.7). The groups appeared to be similar in treatment management, duration of hospitalization, and blood transfusion needs (p=0.3, p=0.6, and p=0.5, respectively). Additionally, no significant difference was observed between the groups in the evaluation of ruptured ectopic pregnancies (p=0.5). In the subgroup analysis of tubal ruptured ectopic pregnancies, no significant difference was observed., Conclusion: To the best of our knowledge, there are few studies evaluating the effect of the pandemic on tubal ectopic pregnancies in the literature. Although we did not report statistically significant differences between groups in our study, given the potential prolonged duration of the pandemic, healthcare professionals should actively prompt their patients to seek necessary medical assistance.

Objective: To explore the factors associated with trophoblastic infiltration in ampullary pregnancy from the perspective of clinical and pathologic characteristics., Methods: A single-center, retrospective, clinicopathologic cohort study was conducted in women who were diagnosed with tubal pregnancy and underwent salpingectomy in the International Peace Maternal and Child Health Care Hospital from January 2018 to June 2021., Results: A total of 333 eligible women diagnosed with ampullary pregnancy were included in the analysis. Multivariate logistic analysis showed that preoperative β-human chorionic gonadotropin greater than 3000 IU/L (adjusted odds ratio [aOR] 3.77, 95% confidence interval [CI] 2.02-7.03), and vascular remodeling phenomenon (aOR 4.34, 95% CI 2.41-7.83) were positively correlated with the infiltration of extravillous trophoblasts into serosa, while presence of chronic inflammation of the fallopian tube was a negatively corellated factor (aOR 0.49, 95% CI 0.29-0.85)., Conclusion: The depth of trophoblastic infiltration in tubal pregnancy may be related to the presence of chronic inflammation in the fallopian tube. A tubal pregnancy in a tube with chronic salpingitis is more likely to develop into an abortive ectopic pregnancy; whereas in a fallopian tube without chronic inflammation, the risk of it developing into a ruptured ectopic pregnancy increases. Hence, early identification is needed to properly address this dangerous pregnancy situation., (© 2023 The Authors.

Purpose: To investigate the association between different treatments of tubal ectopic pregnancy (EP) -expectant management, methotrexate (MTX), selected or recommended laparoscopic surgery-and the subsequent reproductive outcomes., Methods: We conducted a retrospective cohort study including 228 EPs. The patients were divided into four treatment groups: 28 (12.3%) with expectant management successfully, 60 (26.3%) with MTX successfully, 140 patients with laparoscopic salpingectomy, of which 47 (20.6%) were assigned to selected surgery group because they opted for surgical treatment versus MTX, 93 (40.8%) were assigned to recommended surgery group as recommended by the attending physician., Results: The recommended surgery group had the lowest rate of intrauterine pregnancy (IUP) (77.42%) and live birth (LB) (72.04%), while the incidence of recurrent EP (REP) (20.43%) was the highest, but the statistical differences were not significant. We did not observe significant differences of the EP-IUP time interval, rates of LB and miscarriage (MIS) between the four groups. Compared to the MTX group, recommended surgery was negatively associated with IUP (adjusted OR, 95%CI: 0.34, 0.11-1.03) and LB (0.35, 0.14-0.92), while it had higher risk for REP (3.48, 1.03-11.74) in the subsequent pregnancy. Further, compared to selective surgery group, recommended surgery was negatively associated with IUP (0.15, 0.03-0.68) and LB (0.23, 0.07-0.74), while it had higher risk for REP (6.83, 1.43-32.67) in the subsequent pregnancy. Expectant treatment was negatively associated with assisted reproductive technology (ART) (0.08, 0.02-0.40) compared with MTX. Of the185 patients who had LBs, all adverse outcomes were not statistically different between the four groups., Conclusion: Patients with recommended laparoscopic salpingectomy had worse reproductive outcomes than the other treatment groups. The disease status of EP may play an important role in the association rather than the surgery alone., (© 2022.

Abstract: Ectopic pregnancy is the most common cause of maternal mortality in the first trimester of pregnancy. The aim of this study was to find risk factors and clinical characteristics associated with ruptured ectopic pregnancies at a medical center in eastern Taiwan in a 19-year period. This was a retrospective observational study that included patients diagnosed with ectopic pregnancy between August 1999 and December 2018. Data about the demographic variables, initial presentation, pre-treatment beta-human chorionic gonadotropin levels, treatment routes (laparoscopy or laparotomy), surgical methods (salpingostomy or salpingectomy), operation time, blood loss amount, the status of ectopic pregnancy (ruptured or unruptured), the requirement for transfusion, and duration of hospital stay were collected. The categorical and continuous variables were analyzed using the correlation coefficients. This study included 225 women who were diagnosed as having an ectopic pregnancy. There were 49 and 176 women with unruptured and ruptured ectopic pregnancies, respectively. The beta-human chorionic gonadotropin levels, history of previous ectopic pregnancy, pelvic inflammatory disease, tubal surgery, abdominal history, and vaginal bleeding were not significantly different between the 2 groups. The ratio of women with abdominal pain was significantly higher in the ruptured ectopic pregnancy group than in the unruptured group (89.1% vs. 63.8%, respectively, P < .001). Preoperative hemoglobin was lower in the ruptured group compared with the unruptured group (P < .001). Blood loss, postoperative hemoglobin, and blood transfusion were significantly higher in the ruptured group than in the unruptured group (P = .000 and P = .001 for blood loss and blood transfusion, respectively). Multiple logistic regression analysis revealed that abdominal pain and blood loss were associated with ruptured tubal pregnancies (adjusted odds ratio [95% confidence intervals]: 3.42 {1.40, 8.40}; 1.01 {1.005, 1.014}, respectively). In conclusion, early pregnancy with abdominal pain, more parity, and lower preoperative hemoglobin should be aware of the possibility of ruptured ectopic pregnancy. More blood loss, transfusion and lower postoperative hemoglobin were also noted with ruptured ectopic pregnancy., Competing Interests: The authors have no conflicts of interests to disclose., (Copyright © 2022 the Author(s).

Purpose: The aim of this study was to investigate characteristics associated with ectopic pregnancy (EP) that could be utilized for predicting morbidity or mortality., Methods: This was a retrospective analysis of pregnancy-related records from a tertiary center over a period of ten years. Data on age, gravidity, parity, EP risk, amenorrhea duration, abdominal pain presence and location, β-human chorionic gonadotropin (β-HCG) level, ultrasound findings, therapeutic intervention, exact EP implantation site and length of hospital stay (LOS) were obtained from the database. The LOS was used as a proxy for morbidity and was tested for an association with all variables. All statistical analyses were conducted with Stata® (ver. 16.1, Texas, USA)., Results: The incidence of EP in a cohort of 30,247 pregnancies over a ten-year period was 1.05%. Patients presented with lower abdominal pain in 87.9% of cases, and the likelihood of experiencing pain was tenfold higher if fluid was detectable in the pouch of Douglas. Only 5.1% of patients had a detectable embryonic heartbeat, and 18.15% had one or more risk factors for EP. While most EPs were tubal, 2% were ovarian. The LOS was 1.9 days, and laparoscopic intervention was the main management procedure. The cohort included one genetically proven dizygotic heterotopic pregnancy (incidence, 3.3 × 10 - 5 ) that was diagnosed in the 7th gestational week. The only association found was between the β-HCG level and LOS, with a linear regression β coefficient of 0.01 and a P-value of 0.04., Conclusion: EP is a relatively common condition affecting approximately 1% of all pregnancies. β-HCG correlates with EP-related morbidity, but the overall morbidity rate of EP is low regardless of the implantation site. Laparoscopic surgery is an effective therapeutic procedure that is safe for managing EP, even in cases of heterotopic pregnancy.

Objective: During the 2020 COVID-19 pandemic there was a decrease in emergency room arrivals. There is limited evidence about the effect of this change in behavior on women's health. We aimed to evaluate the impact of the COVID-19 pandemic on the diagnosis, treatment and complications of women presenting with a tubal Ectopic Pregnancy (EP)., Study Design: This is a single centre retrospective cohort study. We compared the clinical presentation, treatment modalities and complications of all women presenting in our institution with a tubal EP during the COVID-19 pandemic between 15 March and 15 June 2020, with women who were treated in our institution with the same diagnosis in the corresponding period for the years 2018-2019., Results: The study group included 19 cases of EP (N = 19) that were treated between the 15 March 2020 and 15 June 2020. The control group included 30 cases of EP (N = 30) that were admitted to in the corresponding period during 2018 and 2019. Maternal age, parity, gravity and mode of conception (natural vs. assisted) were similar between the two groups. There was no difference in the mean gestational age (GA) according to the last menstrual period. In the study group more women presented with sonographic evaluation of high fluid volume in the abdomen than in the control group (53 % vs 17 %, P value 0.01). This finding is correlated with a more advanced disease status. In the study group there was a highly statistically significant 3-fold increase in rupture among cases (P < 0.005) and a 4-fold larger volume of blood in the entrance to the abdomen (P < 0.002). We found that there were no cases of ruptured EP in the group of women who were pregnant after assisted reproduction., Conclusion: We found a higher rate of ruptured ectopic pregnancies in our institution during the COVID-19 pandemic. Health care providers should be alerted to this collateral damage in the non-infected population during the COVID-19 pandemic., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 Elsevier B.V.

The aim of this study was to compare the success rate of methotrexate (MTX) treatment in patients with recurrent ectopic pregnancy (REP) and primary EP (PEP). A retrospective cohort study. The study cohort comprised all patients diagnosed with an EP and treated by intention with single-dose regimen of intramuscular MTX in a tertiary medical centre during 2010-2018. Cases (REP) and controls (PEP) were compared.262 patients had PEP and 32 had a REP. Women with REP had significantly higher gravidity order and higher incidence of previous abortions (5 vs. 3, median, p  < .001, 59.3% vs. 32.8%, p  < .001, respectively). Women with REP had a higher proportion of a history of previous surgery in general, and specifically pelvic surgery (46.8% vs. 20.6%, p  < .001, 24.4% vs. 7.2%, p  < .001, respectively). Treatment success was lower in the REP group (40.6% vs. 66.4%, p  = .006, Odds ratio 0.34, 95% confidence interval 0.16, 0.73). In a logistic regression analysis, the only factor found to be independently associated with treatment failure was REP (adjusted odds ratio 0.30, 95% confidence interval 0.12, 0.77, p  = .01). Our study suggests that medical treatment success with a single-dose regimen of MTX is lower than expected among REP cases, suggesting that different treatment approach should be considered in this setting.Impact statement What is already known on this subject ? There is paucity of data regarding success rate of methotrexate treatment for a recurrent ectopic pregnancy (REP). What do the results of this study add? Medical treatment success with a single-dose regimen of MTX in patients with a REP is lower than expected What are the implications of these findings for future clinical practice and/or further research? As medical treatment success with a single-dose regimen of MTX for women with a REP is lower than expected, different treatment approach should be considered. Further and prospective studies with a larger sample size are needed to confirm our findings.

Objective: To evaluate if a decreasing human chorionic gonadotropin (hCG) between day (D) 1 and D7 is an equal or better predictor of tubal ectopic pregnancy (EP) resolution following methotrexate (MTX) treatment than the current standard of care., Study Design: This was a retrospective cohort prognostic accuracy study of women with a transvaginal ultrasound (TVS)-confirmed tubal EP (November 2006-December 2015). After single-dose MTX treatment, D4/7 hCG ratios were compared with that of D1/D7 in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) to predict EP resolution., Results: Tubal EP was diagnosed in 301/7350 (4.1%) women who underwent TVS for early pregnancy-related complaints. The patients were managed accordingly: expectant, 84/301 (27.9%); MTX, 65/301 (21.6%); surgery, 152/301 (50.5%). A D1/D7 hCG ratio ≤0.85 predicted successful resolution of tubal EPs (P < 0.001) treated with MTX with sensitivity 0.84 [95% confidence interval (CI), 0.69-0.94]), specificity 0.71 [95%CI, 0.48-0.89], PPV 0.84 [95%CI, 0.69-0.94], NPV 0.84 [95%CI, 0.69-0.94], which is comparable to the prognostic performance of the D4/7 protocol., Conclusion: In patients with tubal EP carefully selected for and treated with MTX, it may be reasonable to eliminate the D4 hCG in the follow-up algorithm., (Copyright © 2020 Elsevier B.V.

Endoscopic surgery of ectopic pregnancy is actually the gold standard for the management of fallopian tubal diseases. A survey was conducted to evaluate fertility in patients who underwent endoscopic management for ectopic pregnancy. A retrospective study was conducted at the department of general and endoscopic surgery of the Point "G" teaching hospital, in Bamako, Mali, from January 1st 2007 to December 31, 2016. Forty-eight (48) patients who underwent endoscopic management of tubal ectopic pregnancy and who have been followed up for fertility were included in this study. Statistical tests used were X2 or Fisher test and their confident interval, p <1 % has been considered as statistically significant. The therapeutic score of Pouly was less than 4 in 25.0% (n = 12). The return to fertility was observed among 48.0% of patients (n = 23). The chance of conception was less than 80.0% after the fourth postoperative year (p=0.001). The outcome of pregnancies has been seventeen full-term pregnancies, three ectopic pregnancies and three miscarriages. The occurrence of pregnancy after endoscopic management indicated for ectopic pregnancy is possible. However, many factors can influence the future conception.

Study Objective: Tubal stump pregnancy is a rare variant of ectopic pregnancy. The aim of this study was to evaluate laparoscopic surgery for tubal stump pregnancy and to investigate postoperative pregnancy outcomes., Design: Retrospective study., Setting: University-affiliated hospital., Patients: Patients (n = 42) diagnosed with tubal stump pregnancy., Interventions: Data were extracted from the electronic medical records system of the hospital., Measurements and Main Results: Patients diagnosed with tubal stump pregnancy between June 2010 and July 2018 were included. Data included demographic characteristics, gravidity and parity, history of pelvic surgery, clinical features, and treatment. All procedures were laparoscopic. Postoperative pregnancy outcomes were identified from electronic medical records or by telephone. Patients' mean age was 30 (range, 21-39) years. Twelve of 42 tubal stump pregnancies (28.6%) had ruptured ectopic pregnancy at the time of operation. The remaining 30 cases had intact stump pregnancy during surgery. Patients were followed for a mean of 31 (range, 10-60) months. Follow-up data were available for 33 of 39 patients (3 with heterotopic tubal stump pregnancy were not included in follow-up data because all resulted in a live births and had no desire for future pregnancy). Eighteen of 28 patients (64.3%) who attempted conception had intrauterine pregnancies (IUPs) during the follow-up period; of these 18 IUPs, 14 (77.8%) resulted in live births. There was 1 case of uterine rupture in a singleton pregnancy at 20 +5 weeks that resulted in fetal death. Three of 18 IUPs (16.7%) ended in the first trimester with spontaneous abortions., Conclusion: Laparoscopic surgery is a feasible option for tubal stump pregnancy and is associated with favorable pregnancy outcomes., (Copyright © 2019 AAGL.

Chlamydia trachomatis (CT) infection is an important factor for tubal pregnancy. However, whether Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) infections are also involved in tubal pregnancy remains unknown. This study is aimed to detect CT, UU, and MH in cervical secretions from patients with tubal pregnancy and control women in early pregnancy, to explore their prevalence rates and drug susceptibilities. Analysis was performed on patients with tubal pregnancy and those requiring termination of early pregnancy at <12 weeks from July 2013 to March 2014. Cervical secretions were tested for UU/MH with a UU/MH isolation and culture kit and for CT antigen by an immunochromatographic assay. Mycoplasma samples were tested for resistance to 12 antibiotics. There were no cases of CT infection detected. Mycoplasma infection rates (single or mixed) were similar in the tubal pregnancy and control groups, but the total rate of infection was higher for tubal pregnancy. All MH samples were sensitive to tetracyclines as well as josamycin and azithromycin. Josamycin and clarithromycin were effective against all UU cultures. Over 50% of the samples tested were resistant to ciprofloxacin.

Study Objective: To identify factors predictive of persistent ectopic pregnancy (PEP) in women who have undergone laparoscopic salpingostomy or salpingotomy for tubal pregnancy., Design: Retrospective cohort study (Canadian Task Force classification II-2)., Setting: Tertiary referral center., Patients: Ninety-nine women who underwent laparoscopic tubal preservation surgery for ectopic pregnancy., Interventions: Seventy women underwent laparoscopic salpingostomy, and the remaining 29 women underwent laparoscopic salpingotomy., Measurements and Main Results: Factors predicting PEP were evaluated. The change in serum beta human chorionic gonadotropin (β-hCG) levels from baseline observed between postoperative days 5 and 10 (ChCGD5-10) was a predictor of PEP (odds ratio [OR], 0.80; p = .01). Based on receiver operating characteristic (ROC) curve analysis, a cutoff value of 93.1% was determined, with an area under the ROC curve of 0.95 (sensitivity, 85.7%; specificity, 100%). Nonetheless, when considering perioperative variables only, body mass index (BMI) was identified as a predictor of PEP (OR, 0.71; p = .03). Based on the ROC analysis, a BMI cutoff value of ≤22 kg/m 2 was determined, with an ROC area of 0.73 (sensitivity, 43.2%; specificity, 100%). In addition, a higher baseline β-hCG level (hazard ratio [HR], 1.0002; p = .009) and left tubal pregnancy (HR, 6.46; p = .03) were predictive of recurrent ectopic pregnancy. There were no differences in the perioperative outcomes, PEP rates, or subsequent intrauterine pregnancy rates between the salpingostomy and salpingotomy groups. In addition, surgical method was not a predictor of recurrent ectopic pregnancy., Conclusions: ChCGD5-10 was identified as a predictor for PEP, suggesting that it might be more clinically useful for the follow-up of PEP. When considering perioperative variables only, BMI was a predictor for PEP. In addition, there was no significant difference in clinical outcomes between the salpingostomy and salpingotomy groups., (Copyright © 2018 AAGL. Published by Elsevier Inc. All rights reserved.)

Study Objective: To investigate whether there are left-right asymmetries, factors affecting lateral dominance, and clinical feature differences in the left and right sides of tubal pregnancy (TP)., Design: Retrospective study (Canadian Task Force classification II-2)., Setting: International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiao Tong University., Patients: Patients (n = 6186) with TP treated surgically., Interventions: We used data from the digital medical records system of the hospital. Women diagnosed with ectopic pregnancy(EP) between January 2005 and December 2016 in the inpatient department of gynecology were included. All data from the medical files were obtained retrospectively, including demographic characteristics; reproductive, gynecologic, and surgical history; clinical features; and treatment. Patients who were previously treated by salpingectomy or nonsurgical management and those with unknown-site EP or non-TPs were excluded., Measurements and Main Results: The overall frequency of right-sided TP was 54.48% (3370/6186), which is significantly higher than 50% (p < .001, binominal test). The proportion of right-sided TPs decreased with age (p for trend = .007) and from the proximal (interstitial) end to the distal (fimbrial) end of the tube (p for trend = .017). Of the TP patients with a corpus luteum, we found the corpus luteum was more frequently located in the right ovary (p < .001) and in the contralateral ovary to the TP side in 41.38% of cases. However, tubal rupture was more frequent in left TP than the in right TP (p = .005)., Conclusion: The left-right asymmetries of TP include right-side dominance and the clinical feature differences between the 2sides of TP., (Copyright © 2018.

Background: An ectopic pregnancy after hysterectomy is a rare but potentially life-threatening event. Women with this condition might not be appropriately investigated, resulting in delays in diagnosis and treatment., Objectives: To characterize cases of ectopic pregnancy occurring after hysterectomy., Search Strategy: PubMed, Embase, Scopus, and Web of Science were searched using the terms "pregnancy, abdominal" or "pregnancy, tubal" or "pregnancy, ectopic" and "hysterectomy" or "post-hysterectomy" or "post hysterectomy.", Selection Criteria: Case reports or case series published in English up to October 10, 2016, were included. Patients were included if the diagnosis was confirmed by definitive tests such as serum or urine β-human chorionic gonadotropin (β-hCG) testing, ultrasonography evidence of pregnancy, or histology., Data Collection and Analysis: Patient characteristics were extracted via a standard spreadsheet., Main Results: A total of 57 patients were included in the analysis. Abdominal pain was the predominant symptom. Implantation in a remaining fallopian tube was common. Most patients were managed surgically., Conclusions: A high index of suspicion and a low threshold for performing a β-hCG pregnancy test is recommended in all women presenting with clinical symptoms of ectopic pregnancy, regardless of the hysterectomy status. This could lead to earlier diagnosis and fewer complications., (© 2017 International Federation of Gynecology and Obstetrics.)

Aim: To describe the frequency and temporal trends of inpatient hospitalization for tubal ectopic pregnancy as well as patients' characteristics, determinants and the current national trends in surgical management of ectopic pregnancy., Methods: We conducted a retrospective, cross-sectional analysis of patients who were treated for tubal ectopic pregnancy in an inpatient hospital setting in the United States from 1998 to 2011 using data from the Nationwide Inpatient Sample databases. National frequency and significant changes in the rate of surgical management of tubal ectopic pregnancy in the inpatient setting are described., Results: The study included 334 639 tubal ectopic pregnancies for women aged 18-50 in the United States from 1998 to 2011. The rate of tubal ectopic pregnancy (per 10 000 maternal admissions) decreased from 77.2 in 1998 to 40.5 in 2011. The proportion of tubal ectopic pregnancies for which salpingostomy was performed decreased from 17.0% in 1998 to 7.0% in 2011, while the rate of salpingectomy increased from 69.3% in 1998 to 80.9% in 2011. The temporal change in surgical choice was not different in states with comprehensive in vitro fertilization insurance mandates., Conclusion: The rate of tubal ectopic pregnancy managed in the inpatient setting in the United States decreased 5% annually between 1998 and 2011. The rate of salpingectomies performed annually increased whereas that of salpingostomy decreased over time. The surgical approach selected for the management of tubal ectopic pregnancies was not influenced by a state's in vitro fertilization mandate status., (© 2018 Japan Society of Obstetrics and Gynecology.)

Background: There are several accepted approaches to management of ectopic pregnancy, both surgical and non-surgical. When a surgical approach is used, there appears to be an equipoise between tubal preservation and removal. We sought to determine the patterns of surgical management of ectopic pregnancy in Australia since the year 2000., Materials and Methods: Data regarding hospital admissions for ectopic pregnancy were extracted from the Australian Institute of Health and Welfare national procedural dataset for the years 2000-2013. Surgical procedures were classified as open or laparoscopic, and involving salpingotomy or salpingectomy (tubal removal). The results were stratified into age bands., Results: Over the study period hospital admission rates for ectopic pregnancy rose in women under the age of 30, without an increase in surgical procedures, while the rate of surgical procedures fell in women in older age groups. Rates of management of ectopic pregnancy via laparotomy fell in all age groups, as did rates of tubal preservation., Conclusion: Since the year 2000 there have been changes in the management of ectopic pregnancy, with significant reductions in open surgery and tubal preservation., (© 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

Ectopic pregnancy is defined as a pregnancy that occurs outside of the uterine cavity. The most common site of ectopic pregnancy is the fallopian tube. Most cases of tubal ectopic pregnancy that are detected early can be treated successfully either with minimally invasive surgery or with medical management using methotrexate. However, tubal ectopic pregnancy in an unstable patient is a medical emergency that requires prompt surgical intervention. The purpose of this document is to review information on the current understanding of tubal ectopic pregnancy and to provide guidelines for timely diagnosis and management that are consistent with the best available scientific evidence.

Background: Ectopic pregnancy (EP) is a major problem in obstetrics as there is evidence of increasing incidence throughout the world. It is an important cause of maternal morbidity and mortality. In Pakistan, the care seeking behaviour among female is limited that makes female vulnerable to die due to complication of ectopic pregnancy. The aim of this study is to determine the frequency of tubal rupture in ectopic pregnancy in Pakistani patients., Methods: In this crosssectional study data pertaining to age, gestational age, parity and duration of presenting symptoms were collected and analysed., Results: 80 patients were diagnosed to have ectopic pregnancy. The frequency of tubal rupture was 91.25%. It is encountered significantly more often in women with age of 26 years. More tubal rupture is found in patient with low parity, in which the frequency of tubal rupture is up to 100% and decrease up to 78.6% with increasing parity up to four. Furthermore, it is noted that increase in gestational age from 8 weeks to 10 weeks caused an increase in frequency of tubal rupture from 80 to 100% respectively. It is also noted that earlier the patient presents the lesser is the frequency of tubal rupture, as compared to late presentation beyond 3-4 days which make frequency up to 95%., Conclusions: Tubal rupture is still common cause of maternal morbidity and mortality, and is still a major challenge in gynaecological practice. Creating awareness amongst midwives and GPs regarding early diagnosis can contribute to decrease the mortality, morbidity and fertility loss related to EP.

Rupture of a gravid uterus is an obstetric emergency. Risks factors include a scarred uterus but also spontaneous rupture of an un- scarred uterus during pregnancy is possible. The authors present two cases of a spontaneous complete uterine rupture during pregnancy. The first case had only a past history of dilatation and curettage for abortion; the second case had a past history of dilatation and curettage for abortion and a monolateral laparoscopic salpingectomy for ectopic pregnancy. They presented with abdominal pain and after ultrasound scan, uterine ruptures were diagnosed. These cases show that there should be a high index of suspicious of uterine rupture in a gravid woman with a history of curettage for the possible presence of misunderstood uterine scar and in women with a past history of salpingectomy with or without corneal resection. Appropriate counseling and close follow-up might help to avoid such obstetrical catastrophes. To provide more insight into the possible risk factors for prelabor uterine rupture in pregnancy, a literature review was performed.

The present authors analyzed patients' backgrounds and pre-surgical findings to clarify the risk factors of rupture of fallopian tubal pregnancy. The surgical findings 113 cases were clearly diagnosed as fallopian tubal pregnancy with or without rupture. Twenty-six cases of fallopian tubal pregnancy were ruptured and 87 cases were not ruptured at the time of operation. The risk factors of fallopian tubal rupture were assessed by Chi-square for independence test and multiple regression analysis. Obesity (BMI over 26), prior birth history, social welfare entitlement, ultrasonography findings of fetal heart movement, and pre-surgical serum beta-hCG level more than 3,000 mIU/ml patient were significantly higher risk in fallopian tubal rupture. Fertility treatment patient were at significantly lower risk for fallopian tubal rupture. Higher beta-hCG levels, especially >3,000 mIU/ml is associated with increased risk of fallopian tubal rupture in ectopic pregnancy.

In this paper we summarize our experience in diagnosis and treatment of 402 retrospectively collected tubal EP and review the most recent topics from the literature. Systemic Methotrexate (MTX) was effective in 56 out of 65 patients (failure rate 13.8%), in whom hCG level was significantly lower when compared to the failure group (p&lt;0,05); we performed 299 salpingectomies, 297 of whom through laparoscopic approach. MTX single-dose is safe and effective in eligible patients; surgery represents the treatment of most of the EPs, mainly through laparoscopic approach.

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., (Copyright © 2015 John Wiley & Sons, Ltd.)

Aim: Ectopic pregnancies account for 10-15% of all maternal deaths. Rupture of an ectopic pregnancy is an urgent medical situation, therefore prediction of any tubal rupture before its occurrence is extremely important. The aim of this study was to evaluate the tubal rupture rate in different treatment modalities in EP cases and to find a hCG level on admission and/or size of ectopic mass predictive for tubal rupture., Methods: Demographic data and medical data were extracted from patient charts for 211 cases who had diagnosis of tubal ectopic pregnancy. Women with tubal rupture were compared to those without rupture., Results: Expectant management, single dose methotrexate and primary surgical treatment were applied to 83 cases (39%), 93 cases (44%) and 35 cases (17%), respectively. The tubal rupture occurred in 14.7% of the study population. If the EP mass diameter is <2 cm, no tubal rupture was found. hCG values at admission were found to be predictive for rupture. On admission, hCG level of 1855 IU/L had 93.5%, sensitivity and 29% positive predictive value for tubal rupture., Conclusion: In tubal ectopic pregnancy cases, hCG level on admission and size of ectopic pregnancy mass can predict tubal rupture.

Objective: To identify risk factors for ovarian pregnancy (OP) and compare clinical features between OP and tubal pregnancy (TP) patients., Design: Case-control study., Setting: University hospital., Participants: A case-control study was conducted from January 2005 to May 2014. Women diagnosed with OP were recruited as the case group (n=71), 145 women with TP and 146 with intrauterine pregnancy (IUP) were matched as controls at a ratio of 1:2:2. Women who refused interviews or provided incomplete information were excluded., Results: OP risk was lower than TP risk in women with serological evidence of Chlamydia trachomatis infection (adjusted OR1 0.17, 95% CI 0.06 to 0.52), previous adnexal surgery (adjusted OR1 0.25, 95% CI 0.07 to 0.95), and current levonorgestrel emergency contraceptive use (adjusted OR1 0.24, 95% CI 0.07 to 0.78). In vitro fertilisation-embryo transfer (IVF-ET) carried a higher risk of OP (adjusted OR1 12.18, 95% CI 2.23 to 66.58) than natural conception. When Controlled by IUP women, current users of intrauterine devices (IUDs) carried a higher risk of OP than non-users of any contraceptives (adjusted OR2 9.60, 95% CI 1.76 to 42.20). β-Human chorionic gonadotropin (hCG) levels on the day of surgery were higher in OP patients than in TP patients (p<0.01). Women with OP were less likely to initially present with vaginal bleeding than those with TP (p=0.02). Moreover, shock (p=0.02), rupture (p<0.01), haemoperitoneum (p<0.01) and emergency laparotomy (p<0.01) were more common in the OP group than in the TP group., Conclusions: IVF-ET and IUD use may be risk factors for OP, and OP patients tend to have high β-hCG levels and a poor clinical outcome (shock, rupture, haemoperitoneum and need for emergency laparotomy). Our findings may contribute to the prevention and early diagnosis of OP., (Published by the BMJ Publishing Group Limited.

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., (© 2013 The Authors.

Objective: To validate the efficacy and safety of our clinical protocol for expectant management of selected women diagnosed with tubal ectopic pregnancy., Methods: This was a prospective observational study carried out in the early pregnancy unit of a London inner-city university teaching hospital from 1(st) January 2008 to 31(st) May 2011. All women presenting with suspected early pregnancy complications were assessed clinically and by transvaginal ultrasound. Those with a conclusive ultrasound diagnosis of tubal ectopic pregnancy were selected for either surgical or expectant management. Selection criteria for expectant management were clinical stability with no or minimal abdominal pain, no evidence of significant hemoperitoneum on ultrasound scan, ectopic pregnancy measuring < 30 mm in mean diameter with no evidence of embryonic cardiac activity, serum β-human chorionic gonadotropin (β-hCG) < 1500 IU/L and the woman's consent. All women selected for expectant management were followed up as outpatients until the ectopic pregnancy regressed spontaneously (resolution of clinical symptoms, serum β-hCG < 20 IU/L/negative urine pregnancy test) or surgical intervention was required. We recorded the rate of interventions, complications and length of follow-up., Results: During the study period 339/11 520 (2.9% (95% CI, 2.59-3.21%)) women were diagnosed with tubal ectopic pregnancy. Six women opted to participate in an ongoing randomized controlled trial and were excluded from further analysis. One hundred and sixty-five (49.5% (95% CI, 44.2-55.0%)) of the 333 remaining women met the criteria for expectant management; 146/333 (43.8% (95% CI, 38.5-49.1%)) of them opted for expectant management and 104/333 (31.2% (95% CI, 26.2-36.2%)) of all tubal ectopics resolved without requiring any intervention. All women with failed expectant management were treated by laparoscopic salpingectomy/salpingotomy and none of them required a blood transfusion., Conclusion: Our clinical protocol for expectant management of tubal ectopic pregnancies eliminates the need for medical or surgical treatment in more than a third of women diagnosed with tubal ectopic pregnancy with a minimum risk of adverse outcome., (Copyright © 2013 ISUOG.

Background: Ectopic pregnancy (EP) is an important cause of morbidity and mortality amongst women of reproductive age. Tubal EP is well described in industrialised countries, but less is known about its impact in low-resource countries, in particular in the South Pacific Region., Methods: We undertook a retrospective review of women with tubal EP treated at a provincial referral hospital in coastal Papua New Guinea over a period of 56 months. Demographic and clinical variables were obtained from patients' medical records and analysed. The institutional rate of tubal EP was calculated, and diagnosis and management reviewed. Potential risk factors for tubal EP were identified, and delays contributing to increased morbidity described., Results: A total of 73 women had tubal EP. The institutional rate of tubal EP over the study period was 6.3 per 1,000 deliveries. There were no maternal deaths due to EP. The mean age of women was 31.5+/-5.7 years, 85% were parous, 67% were rural dwellers and 62% had a history of sub-fertility. The most commonly used diagnostic aid was culdocentesis. One third of women had clinical evidence of shock on arrival. All women with tubal EP were managed by open salpingectomy. Tubal rupture was confirmed for 48% of patients and was more common amongst rural dwellers. Forty-three percent of women had macroscopic evidence of pelvic infection. Two-thirds of patients received blood transfusions, and post-operative recovery lasted six days on average. Late presentation, lack of clinical suspicion, and delays with receiving appropriate treatments were observed., Conclusions: Tubal EP is a common gynaecological emergency in a referral hospital in coastal PNG, and causes significant morbidity, in particular amongst women residing in rural areas. Sexually transmitted infections are likely to represent the most important risk factor for tubal EP in PNG. Interventions to reduce the morbidity due to tubal EP include the prevention, detection and treatment of sexually transmitted infections, identification and reduction of barriers to prompt presentation, increasing health workers' awareness of ectopic pregnancy, providing pregnancy test kits to rural health centres, and strengthening hospital blood transfusion services, including facilities for autotransfusion.

Objective: To investigate the level of expression of the cytokines interleukin (IL) -8 and IL-6 and their receptors in fallopian tubes with tubal ectopic gestation., Design: Immunohistochemistry (IHC) was used to study the expression of IL-8, CXCR1, CXCR2, IL-6, and IL-6 receptor alpha in fallopian tubes with tubal ectopic gestation in comparison with normal fallopian tubes., Setting: Hospital., Patient(s): We studied fallopian tubes from 50 patients with tubal ectopic gestation and normal fallopian tubes from 25 patients who had hysterectomy and bilateral salpingo-oopherectomy for uterine or ovarian lesions., Intervention(s): The expression of the chemokines/cytokines and their receptors was evaluated by IHC., Main Outcome Measure(s): Level of expression and tissue distribution of the different antigens., Result(s): IHC results showed that the expression levels of IL-6 and IL-8, as well as CXCR1, were significantly up-regulated, particularly near the implantation site in fallopian tubes with tubal gestation, while the expression levels of CXCR2 and IL-6Rα were not changed in comparison with normal fallopian tubes., Conclusion(s): The results suggest a role for IL-6, IL-8, and CXCR1 in the pathophysiology of tubal ectopic gestation., (Copyright © 2012 American Society for Reproductive Medicine.

Objective: To investigate long-term postoperative outcomes of conservative and radical surgery in ectopic tubal pregnancies, and evaluate the results of these techniques., Methods: A total of 145 patients that operated for tubal pregnancy between January 2006 and January 2009 were reviewed. Data on patient age, reproductive and surgical history history of ectopic pregnancies, serum hCG levels at the time of diagnosis and intraoperative observation were retrospectively obtained from hospital records. Telephone interviews were used to obtain information about exact postoperative time interval in which the patients were trying to get pregnant, and the time when they spontaneously became pregnant., Results: There was no significant difference in cumulative spontaneous intrauterine pregnancy rate for a 2-year of conception period subsequent to conservative (64.3%) and radical (58.3%) surgery (p = 0.636). During the same time interval, the rates of development of ectopic pregnancy for the conservative and radical surgery groups were 17.9% and 4.2%, respectively (p = 0.093). The patients who developed ectopic pregnancy after conservative surgery had significantly higher levels of serum hCG levels (7413 +/- 3155 IU/L) compared with those of patients who not-developed ectopic pregnancy (3436 +/- 2668 IU/L) (p = 0.007)., Conclusion: In late-diagnosed cases with higher serum hCG levels, conservative treatment should not be the first choice. Indeed, our results suggested that the cumulative pregnancy rates are not significantly higher and the risk of ectopic pregnancy recurrence may be increased with conservative surgery in late tubal pregnancies.

Objective: To study the association between patient-related risk factors and severe maternal morbidity in women with tubal ectopic pregnancy (EP). Furthermore, to identify substandard care factors in clinical care management of EP., Design: Case-control study., Setting: Not applicable., Patient(s): Case subjects were from the LEMMoN study, a prospective nationwide cohort study. Control subjects were from the ESEP study, an international multicenter randomized controlled trial., Intervention(s): Case subjects were women with tubal EP complicated by severe intra-abdominal hemorrhage necessitating blood transfusion of ≥4 units of packed red blood cells peri- or postoperatively. Control subjects were women with tubal EP who were hemodynamically stable and surgically treated., Main Outcome Measure(s): Patient-related risk factors as: maternal age, gestational age, previous EP, Chlamydia infection, pelvic inflammatory disease, assisted reproductive techniques, and serum hCG level. Substandard care categories classified as unawareness of the clinician, misdiagnosis, and nonadherence to the guideline on EP., Result(s): Twenty-nine case subjects and 99 control subjects were included. The mean serum hCG level was significantly higher in case subjects compared with control subjects, but we found no reliable cutoff level of serum hCG to rule out maternal morbidity. Other risk factors did not differ significantly. Substandard care was scored more often in case subjects (43%) than in control subjects (14%), mainly concerning misdiagnosis., Conclusion(s): No patient-related risk factors for severe intra-abdominal hemorrhage in women with tubal EP were identified. Our findings underpin the importance of awareness of EP among young fertile women and care providers and clinical care management according to the guidelines to prevent severe maternal morbidity., (Copyright © 2012 American Society for Reproductive Medicine.

Objective: To study pregnancy characteristics in women with pheochromocytoma and to improve awareness of this comorbidity among obstetricians and gynecologists., Methods: The diagnosis and treatment of a case of ectopic pregnancy with pheochromocytoma is described., Results: The patient was diagnosed with a ruptured left Fallopian tube isthmus due to pregnancy, with comorbid left adrenal pheochromocytoma., Conclusion: Ectopic pregnancy with heavy bleeding and elevated blood pressure is indicative of pheochromocytoma. Measurement of the levels of urinary vanillylmandelic acid and urinary and serum catecholamines, as well as ultrasonography, can help diagnose this comorbidity.

Objective: To present four cases of twin tubal pregnancies and discuss possible etiologies. Twin tubal pregnancies are a rare event, with incidence rates estimated as 1 out of 725-1,580 of tubal pregnancies., Design: Case series., Setting: Department of obstetrics and gynecology at a tertiary health care facility., Patient(s): All women with twin tubal pregnancy diagnosed and treated in the department during the years 2007-2009, according to electronic files and histologic reports., Intervention(s): None., Main Outcome Measure(s): Artificial reproductive technique preceding twin tubal pregnancies, Result(s): We diagnosed four twin pregnancies of 163 tubal pregnancies, an incidence of 2.4%. Of the four cases, two conceived after gonadotropin stimulation and intrauterine insemination. The third conceived following in vitro fertilization and intracytoplasmic sperm injection. The fourth was a spontaneous conception diagnosed as monochorial monoamniotic twin tubal pregnancy., Conclusion(s): Twin tubal pregnancies may not be as rare as previously thought. Three of the four cases identified during a 2-year period followed artificial reproductive technique. We hope that this report will promote the study of the epidemiology of this event, improve diagnosis, and encourage the development of treatment modalities., (Copyright © 2010.

BACKGROUND An ectopic pregnancy is a pregnancy which occurs outside of the uterine cavity, and over 98% implant in the Fallopian tube. Tubal ectopic pregnancy remains the most common cause of maternal mortality in the first trimester of pregnancy. The epidemiological risk factors for tubal ectopic pregnancy are well established and include: tubal damage as a result of surgery or infection (particularly Chlamydia trachomatis), smoking and in vitro fertilization. This review appraises the data to date researching the aetiology of tubal ectopic pregnancy. METHODS Scientific literature was searched for studies investigating the underlying aetiology of tubal ectopic pregnancy. RESULTS Existing data addressing the underlying cause of tubal ectopic pregnancy are mostly descriptive. There are currently few good animal models of tubal ectopic pregnancy. There are limited data explaining the link between risk factors and tubal implantation. CONCLUSIONS Current evidence supports the hypothesis that tubal ectopic pregnancy is caused by a combination of retention of the embryo within the Fallopian tube due to impaired embryo-tubal transport and alterations in the tubal environment allowing early implantation to occur. Future studies are needed that address the functional consequences of infection and smoking on Fallopian tube physiology. A greater understanding of the aetiology of tubal ectopic pregnancy is critical for the development of improved preventative measures, the advancement of diagnostic screening methods and the development of novel treatments.

The incidence of interstitial pregnancy is rising. Traditional treatment with laparotomy, hysterectomy, or cornual wedge resection is associated with high morbidity and detrimental effects on future fertility. A diverse array of alternate treatments has been introduced over the last 3 decades, with the common goal of achieving a minimally invasive, standardized management strategy. This has been facilitated by impressive strides towards prompt diagnosis, both radiologically and chemically. In this review, we explore the current state of the art diagnostic criteria and the clinically significant diverse therapeutic options with supporting literature. Finally, we propose a structured, best-practice management plan for the once-lethal interstitial pregnancy, based on the current literature., (2010 Mosby, Inc.)

Objective: To evaluate and compare the current approach to the management of ectopic pregnancy between the main two civil hospitals in the north of Jordan., Design: A retrospective study., Material and Methods: A retrospective review was made of the records of all patients with confirmed ectopic pregnancy admitted to Princess Badea Teaching Hospital (PBTH), and King Abdullah University Hospital (KAUH) between January 1, 2005 and December 31, 2005. The total number of deliveries for the same period was obtained from the labor ward records of hospitals. Information regarding demographic data, presenting symptoms, methods of diagnosis and treatment were extracted from individual patient records., Results: There were 50 cases of confirmed ectopic pregnancy in PBTH compared with 20 cases in KAUH. The total number of deliveries at PBTH was 9,000 (1 ectopic/180 deliveries) while at KAUH, the number of deliveries was 3,000 so the ratio was 1: 150. The majority of patients (82%) had ruptured ectopic pregnancy at presentation. All cases at PBTH were managed by laparotomy. Of the 20 cases at KAUH, five cases were managed laparoscopically and three received medical treatment for their ectopics. There was no maternal mortality from ectopic pregnancy or its management at either hospital., Conclusion: The management of ectopic pregnancy in our community is still suboptimal. We recommend the development of clinical protocols for early diagnosis and referral, training in transvaginal scanning and an increase in the use of laparoscopy for the management of ectopic pregnancy.

Objectives: Methotrexate (MTX) has been a prevalent drug in conservative treatment of unruptured tubal pregnancy for many years. However, few researchers have performed morphological and protein analysis simultaneously to evaluate the specific toxic effects of MTX on the fallopian tubes. The aim of this study was to investigate acute and long-term toxic effects of increasing doses of MTX on the fallopian tubes and a possible dose-effect relationship. We also discuss the potential implications for subsequent pregnancies., Study Design: At the 10th day and the 2nd and 3rd months after MTX treatment, a total of 108 females SD rats in estrus stage (27 rats in each group) were collected according to the dose of MTX i.p.: 1, 2, 5mg/kg body weight in groups I, II and III respectively and physiological saline i.p. in group IV for control. Nine rats in each group were killed at each time point and tissues close to the ampulla of the fallopian tubes were dissected for HE staining and routine histological observation. Estrogen receptor (ER) and progesterone receptor (PR) expression was detected by immunohistochemistry and Western blot., Results: Morphological observation showed acute endosalpingitis in group I, becoming more intense with increasing doses of MTX in groups II and III in a reversible mode. Expression of ER in the endosalpinx significantly decreased in parallel with increasing doses of MTX in a dose-effect manner, which was reversible in groups I and II and irreversible in group III. Furthermore, ER and PR could recover close to normal levels in groups I and II after the 3rd month, while they could not restore to normal in group III., Conclusions: These results provide the first evidence that MTX (>or=5mg/kg) can induce long-term, irreversible damage to steroid hormone receptors in the fallopian tubes in a dose-dependent manner. We tentatively suggest that MTX should be used in a relatively small and safe range of dosage in order to avoid impairment and potential risk of subsequent tubal pregnancy or infertility.

Unlabelled: HEADING AIMS: We evaluated tubal disorders, including peritubal adhesions, as risk factors for repeat ectopic pregnancy (REP) after laparoscopic linear salpingotomy (LS) or salpingectomy for tubal pregnancy., Methods: This was a retrospective clinical study in a university hospital., Results: Of 43 women monitored for at least 6 months after LS, 28 (65%) subsequently conceived. In 24 (86%) of these women the pregnancy was intrauterine, and four (14%) had REP. Of 40 women with a unilateral tube monitored for at least 6 months after salpingectomy, 24 (60%) conceived. In 17 (71%) of these women the pregnancy was intrauterine, and seven (29%) had REP. There was no significant difference between groups in postoperative pregnancy or REP rates. There was no significant difference in the mean adhesion score by revised American Fertility Society stage points (re-AFS) at operation and the site of subsequent pregnancy in either the LS or the salpingectomy group, although the mean re-AFS score was significantly higher in women who had REP (3.1) than in those whose subsequent pregnancy was intrauterine (0.4)., Conclusions: There was no significant difference in postoperative pregnancy or REP rates following previous LS or salpingectomy. The re-AFS score appeared to be an accurate predictor of the prognosis of subsequent pregnancies.

Purpose: To investigate the incidence of Tubal Ectopic Pregnancies (TEP) in IVF-ET patients with respect to the status of the fallopian tubes after a previous TEP., Material and Methods: This retrospective study compares patients undergoing 481 IVF-ET cycles after conservatively or surgically treated TEP(s) with a Control Group (idiopathic or male factor for IVF-ET indication). Medical reports of surgery and/or hysterosalpingograms prior to the IVF cycles classified the status of the fallopian tubes., Results: 12 TEPs (8.95%/Pregnancies (PR)) occurred in the Study Group. In the Control Group one TEP (0.75%/PR; p < 0.001) was found. Smoking increased the probability of TEPs (p = 0.0028) and of pathological pregnancies (abortion, biochemical and ectopic PR; (p = 0.0411)). For statistic evolution logistic regression (PROC GENMOD) and a repeated measure model were applied., Conclusion: Women with a previous TEP should be informed about the significantly increased risk for a further TEP in IVF-ET treatment, especially if they are smoking.

Bilateral simultaneous ectopic pregnancy is a very rare clinical condition. Two different subsets of patients can be distinguished: women presenting with the disease as a result of spontaneous conception and those with the condition after undergoing assisted reproduction procedures. This article reviews and analyzes 42 cases of bilateral ectopic pregnancies reported in the last 10 years, proposes a new classification of the disease, and presents some data that should be useful for the clinician who confronts this difficult entity.

Objectives: To evaluate the determinants of tubal rupture in women who suffered from ectopic pregnancy in relation to their demographic profile and medical history., Study Design: This retrospective observational clinical study was conducted in five general hospitals in Vilnius, Lithuania. The population was composed of 879 women with surgically proven ectopic pregnancy. Tubal rupture was diagnosed at the time of surgery. Univariate and multivariate logistic regression analyses were performed to identify the risk factors for tubal rupture., Results: The occurrence of tubal rupture was 29.5% (259/879). It was encountered significantly more often in women with age of > or =35 years (odds ratio 1.9 [1.3-2.8]). Patients whose EP was located in the isthmus were at higher risk of having tubal rupture (odds ratio 3.2 [2.2-4.5]) while known risk factors for EP were not associated with an elevated risk., Conclusions: Our data suggest that age of > or =35 years and implantation in the straightest segment of the tube could be associated with increased rate of tubal rupture. Of particular interest is the overall tubal rupture prevalence (29.5%) observed since these women were managed in an environment where transvaginal ultrasound equipment and quantitative assessment of beta-human chorionic gonadotrophin were not routinely available.

Our objective was to determine the current incidence, clinical pattern, surgical and medical management, maternal morbidity and mortality from tubal pregnancies in Enugu, Nigeria. The records of all patients treated for tubal pregnancy at the University of Nigeria Teaching Hospital, Enugu from 1 January 1997 to 31 December 2003 were reviewed. The number of tubal ectopic pregnancies was 136, while the total number of hospital deliveries was 6,003 giving a ratio of 1:44. There were four maternal deaths due to tubal pregnancy, out of a total of 126 maternal deaths that occurred during the same period. Ectopic pregnancy was prevalent in young single women with a previous history of induced abortion and resultant pelvic infection. The most common mode of treatment is salpingectomy. Most gynaecologists are not competent in operative laparoscopy and often do not use medical management of ectopic pregnancy. However, late presentation with haemoperitoneum limits the use of conservative treatment. Maternal morbidity and mortality due to tubal pregnancy is rising in Enugu, Nigeria. Preventive efforts should aim at health education and liberal contraceptive utilisation. Provision of more sophisticated equipment and tests in the management of ectopic pregnancies may in the long term be economically viable. Currently, autotransfusion is under utilised.

Objective: To present a case of simultaneous splenic and tubal pregnancy following in vitro fertilization., Design: Case report., Setting: University hospital., Patient(s): A 37-year-old woman who had undergone in vitro fertilization and embryo transfer for unexplained infertility at another clinic., Intervention(s): Laparoscopy and laparotomy., Main Outcome Measure(s): Serum concentration of human chorionic gonadotropin (hCG) after salpingosplenectomy., Result(s): After transfer of three embryos following fertilization by intracytoplasmic sperm injection (ICSI) at another clinic, the patient was referred to our hospital with suspicion of ectopic pregnancy. Because tubal pregnancy was suspected, laparoscopic right salpingectomy was performed. Although villi were detected in the resected fallopian tube, the serum hCG concentration did not decrease after the operation and a new intraabdominal hemorrhage was detected. We then suspected abdominal pregnancy in the epigastric region, and performed magnetic resonance imaging, computed tomography, and ultrasound examinations, which revealed implantation at the inferior pole of the spleen. Splenectomy was performed, with the resulting disappearance of intraabdominal hemorrhage and rapid fall of the serum concentration of hCG., Conclusion(s): Assisted reproduction sometimes results in heterotopic pregnancy, but an abdominal pregnancy involving the upper abdominal organs is considered extremely rare. Particularly, splenic pregnancy is usually overlooked and may only be discovered after a sudden intraabdominal hemorrhage. If hemorrhaging is present in the abdominal cavity but pregnancy is not detected within the pelvis, it is advisable to examine patients using imaging techniques to detect any upper abdominal pregnancies.

Objective: Tubal pregnancy remains an important cause of maternal morbidity and mortality. We sought to quantify the relationship of time between symptom onset and treatment and the risk of tubal rupture., Methods: We reviewed inpatient, clinic, and physician office charts of 221 women with tubal pregnancy. We assessed the conditional risk of rupture with passing time and other factors related to rupture., Results: Time between symptom onset and treatment varied from 3 hours to 66 days with an average of 7 days. There was a 32% rupture rate. The conditional risk of rupture was highest within the first 48 hours of symptom onset (5-7%). The risk dropped, leveled off, and remained fairly steady at approximately 2.5% per 24 hours of untreated symptoms. Classic tubal pregnancy signs, symptoms, and tests were not helpful in predicting rupture., Conclusion: The rate of rupture is highest in women with the shortest times between symptom onset and treatment. With passing time, the risk declines, but remains steady despite women's getting into care., Level of Evidence: II-2
