Increased messenger RNA expression of vascular endothelial growth factor and its receptors in the implantation site of the human oviduct with ectopic gestation.

OBJECTIVE: To compare the mRNA expression of vascular endothelial growth factor (VEGF) and its receptors (KDR and flt-1) in the implantation and nonimplantation sites of the human oviduct with ectopic gestation. DESIGN: Prospective observational study. SETTING: University-based Obstetrics and Gynecology Department. PATIENT(S): Ten women undergoing laparoscopic salpingectomy for tubal pregnancy. INTERVENTION(S): The mucosal layer was isolated from the implantation and nonimplantation sites of the oviduct tissue with ectopic gestation. Semiquantitative reverse transcriptase-polymerase chain reaction was performed. MAIN OUTCOME MEASURE(S): The differences in the mRNA expression of VEGF and its receptors between the implantation and nonimplantation sites of the oviduct tissue. RESULT(S): The mRNA expression of VEGF and its receptors, both KDR and flt-1, was significantly higher in the implantation site of the human oviduct with ectopic gestation compared with the nonimplantation site. CONCLUSION(S): The results suggest that VEGF may be the angiogenic factor responsible for the implantation and placentation of an ectopic pregnancy in the oviduct.

Treatment of viable cesarean scar ectopic pregnancy with suction curettage.

OBJECTIVE: Pregnancy in previous cesarean scar is the rarest form of ectopic pregnancy. All reported cases in the literature that were treated with uterine curettage either become unsuccessful or complicated. We aimed to present a case of cesarean scar ectopic pregnancy that was successfully treated with suction curettage without any additional therapy. CASE: A 32-year-old asymptomatic woman, gravida 2, para 1 was referred to our hospital with the possible diagnosis of cervical ectopic pregnancy. Transvaginal and transabdominal sonographic examination revealed the diagnosis of viable ectopic pregnancy in a previous cesarean scar. Suction curettage with carman canulles was performed under transabdominal ultrasonographic guidance. beta-hCG decreased progressively postoperatively. CONCLUSION: Suction curettage under ultrasonography guidance can be used in termination of selected cases (early diagnosed, without symptoms that necessitates emergency intervention) of cesarean scar pregnancy.

Management of patients with ectopic pregnancy with massive hemoperitoneum by laparoscopic surgery with intraoperative autologous blood transfusion.

STUDY OBJECTIVE: To evaluate the feasibility and safety of surgical laparoscopy with intraoperative autologous blood transfusion for ectopic pregnancy with massive hemoperitoneum. DESIGN: Retrospective analysis (Canadian Task Force classification II-1). SETTING: Department of gynecology at a general hospital. PATIENTS: Seventeen consecutive patients with ectopic pregnancy with massive hemoperitoneum. INTERVENTION: Laparoscopic surgery with salvage device-based intraoperative autologous blood transfusion. MEASUREMENTS AND MAIN RESULTS: From January 2000 through June 2005, one hundred and twelve women with ectopic pregnancy (interstitial/cornual: 4; isthmic: 18; ampullary: 86; and ovarian: 4) were treated by laparoscopic surgery. Seventeen patients who demonstrated more than 501 g of intraabdominal bleeding were classified as having massive hemoperitoneum and retrospectively analyzed. Site of pregnancy in these 17 patients was interstitial/cornual: 3; isthmic: 5; ampullary: 7; and ovarian: 2. Except for two women with tubal abortion of ampullary pregnancy, all other patients had rupture at the pregnancy site. During laparoscopic surgery, blood pooled in the abdominal cavity was collected by an irrigation and aspiration procedure, and sent to an autologous blood-salvage device to make concentrated red blood cell solution. Processed blood was immediately transfused back to the patient through a leukocyte reduction filter. The mean amount of estimated intraabdominal bleeding, which was calculated by the difference between the volumes of aspirated and irrigated fluids, was 1362.1 +/- 491.4 g, and the mean volume of reinfused processed blood was 680.6 +/- 209.5 g. No patient received banked blood at any time. The degree of hemoperitoneum was well correlated with the shock index calculated by dividing the heart rate by systolic blood pressure at triage (r = 0.72; 95% CI 0.37-0.89; p = .001). In all cases of massive hemoperitoneum, there was no need for laparotomic conversion, and homologous blood transfusion was avoided. CONCLUSIONS: Even in women with ectopic pregnancy with massive hemoperitoneum, laparoscopic surgery can be safely conducted by experienced laparoscopists with intraoperative autologous blood transfusion if hemodynamic stability is achieved by perioperative management.

Laparotomy to laparoscopy: changing trends in the surgical management of ectopic pregnancy in a tertiary care teaching hospital.

STUDY OBJECTIVE: To review the changing trends in the surgical management of ectopic pregnancy and to evaluate the effect of an ongoing training program for resident surgeons on the rate and success of laparoscopic surgery. DESIGN: Retrospective chart review (Canadian Task Force classification II-3). SETTING: University tertiary medical center. PATIENTS: One thousand forty-six patients with ectopic pregnancy treated at Jackson Memorial Hospital from January 1, 1995, through December 31, 2004. INTERVENTION: A formal, ongoing laparoscopic training program was established in 1999. MEASUREMENTS: The rate of laparoscopy, laparotomy, and conversion for each year was compared with the baseline year of 1995 and between the years before and after the establishment of the training program. RESULTS: Four hundred sixty-eight laparotomies and 578 laparoscopies were successfully completed. The laparoscopic approach rate has increased from 40.9% in 1995 to 86.3% in 2004. By year 2000 and thereafter, significantly more ectopic surgeries were approached through the laparoscope compared with in 1995 (p<.01). By 2000 and thereafter, significantly less conversions occurred compared with the baseline year of 1995 (4.0% vs 18.5%; p = .01). CONCLUSION: Laparoscopy became the primary approach for the management of ectopic pregnancy in part because of resident participation in an ongoing laparoscopy training program.

Ectopic pregnancy. Surgical intervention and perioperative nursing care.

Because of the wide variety of ectopic pregnancies, there is no established routine for surgical removal. Fortunately, many are small, unruptured tubal pregnancies that can be easily removed via laparoscopy. But because these procedures and skills are relatively new, most surgeons continue to use a laparotomy in the treatment of ectopic pregnancy. A skilled OR team is required when faced with a ruptured ectopic pregnancy. The Centers for Disease Control, Atlanta, reports that of the 165 deaths resulting from ectopic pregnancies it studied, hemorrhage was the cause of death in 88% of the cases. According to the study, only one third of these women had surgery, but the researchers suggest that prompt surgical intervention may be the key to preventing mortality.

The use of carbon dioxide laser laparoscopy in the treatment of tubal ectopic pregnancies.

OBJECTIVE: The purpose of this study was to assess the efficacy of the treatment of unruptured tubal ectopic pregnancies by the use of carbon dioxide laser laparoscopy. STUDY DESIGN: A series of 125 consecutive ectopic pregnancies were treated laparoscopically; the tubal pregnancy was removed by a laparoscopic laser technique. Preoperative assessment included monitoring beta-human chorionic gonadotropin levels, use of vaginal ultrasonography, and preoperative and postoperative hematocrit levels. RESULTS: Laparoscopic laser surgery was successful for removal of tubal ectopic pregnancies in all but four patients, in whom a laparotomy was required. Hematocrit levels before and after surgery were similar. The time necessary for beta-human chorionic gonadotropin to fall to nondetectable levels averaged between 3 and 4 weeks. There were five patients who had complications requiring additional surgery and/or medical treatment. CONCLUSION: The techniques are easy to learn, and the use of laparoscopic laser surgery in the treatment of tubal ectopic pregnancies appears to be a safe procedure with definite advantages for both the patient and the physician. There are decreased operating times, shorter hospital stays, and lower medical costs compared with those for major surgery. Subsequent successful intrauterine pregnancy rates are comparable to those of conservative methods previously reported.

Repeat ectopic pregnancy: a study of 123 consecutive cases.

In a study of 1,330 ectopic pregnancies, 123 (9 per cent) patients experienced repeat tubal pregnancies. Of these 123 patients with repeat ectopics, 96 (78 per cent) were surgically sterilized with their second operative procedure. The remaining 27 potentially fertile patients have had nine pregnancies, but only three living children. Cornual wedge resection of the uterine tube predisposed in interstitial pregnancy and to rupture of the uterus in four cases. Four patients had three ectopic pregnancies each. Repair of the involved tube is usually technically possible following linear salpingotomy and should be done if future fertility is desired. If the patient does not desire future pregnancy, she should be sterilized to avoid the risk of repeat ectopic pregnancy.

The value of curettage in the diagnosis of ectopic pregnancy.

The charts of all patients hospitalized between 1978 and 1983 with proved ectopic pregnancies at Northwestern Memorial Hospital, Chicago, and Meir Hospital, Kfar-Sava, Israel, were reviewed. Eighty-four patients with ectopic pregnancies had endometrial tissue available for histologic analyses. Review of the endometrial curettings revealed that the most common endometrium associated with ectopic pregnancy was secretory (39.4%). Proliferative endometrium present 19% of the time was as common a finding as Arias-Stella phenomenon. This study shows that any type of endometrium lacking trophoblasts may be associated with an ectopic pregnancy. The lack of decidual reaction or Arias-Stella phenomenon should not alone lower the clinician's index of suspicion.

Operative management of ectopic pregnancy: a cost analysis.

OBJECTIVES: The purpose of this study was to analyze the cost for hospital-based services related to the operative management of ectopic pregnancies and determine the most cost-conscious approach by distinguishing the constituent components. STUDY DESIGN: This is a retrospective comparative review of every ectopic pregnancy that was surgically managed at the Memorial Medical Center of Long Beach. Unit cost estimates that are based on a cost accounting system were derived and compared between different procedures according to resources used among separate services. RESULTS: Hemodynamic instability significantly increases the cost of management by increasing the length of stay and laboratory costs. Among stable patients laparoscopic excision of ectopic pregnancies saves nearly 25% per case (p < 0.001) compared with laparotomy. However, when we compared all intended laparoscopic excisions (i.e., including the 21% of cases in which laparotomy was eventually done), the savings were markedly reduced. In addition, the cost savings was lost if patients undergoing laparotomy were discharged on or before postoperative day 2. Discharging patients after laparotomy on postoperative day 1 is the least costly management for operative treatment of ectopic pregnancy. CONCLUSIONS: Whereas laparoscopy may decrease recuperation time and incisional scarring, operative cost is not a significant reason to choose laparoscopy over laparotomy in a hemodynamically stable patient, especially as postoperative stays decrease.

New technologies permit safe abortion at less than six weeks' gestation and provide timely detection of ectopic gestation.

OBJECTIVE: The previously held dictum that elective abortion before 6 weeks' gestation carried greater risks than a later procedure was challenged by this protocol. STUDY DESIGN: This study evaluated a protocol for abortion before the customary 6 weeks' gestation. Patients willing to return to the clinic within 72 hours were given the option of elective abortion even when no gestational sac could be visualized with transvaginal ultrasonography. When no chorionic membrane with villi was seen in the curettings, postoperative serum levels of beta-human chorionic gonadotropin confirmed complete evacuation or diagnosed ectopic pregnancy. RESULTS: In 1530 abortion procedures at < 6 weeks' gestation by ultrasonographic criteria no serious complications occurred. In addition, 9 (0.67%) unsuspected ectopic pregnancies were diagnosed. CONCLUSIONS: Abortion before 6 weeks' gestation is safe, given close surveillance. Early termination combined with vaginal ultrasonography and follow-up with beta-human chorionic gonadotropin measurements allows diagnosis of early, unsuspected ectopic pregnancy. Ectopic pregnancy was found to be uncommon in women requesting early abortion.

Association of histologic features and cytogenetic abnormalities in ectopic pregnancies.

OBJECTIVE: To evaluate the association between specific histologic features and cytogenetic abnormalities in ectopic pregnancies. DESIGN: Blinded histologic analysis. SETTING: University hospital. PATIENT(S): Fifty-four patients with ectopic pregnancy for whom successful karyotypes and sufficient histologic material were available. INTERVENTION(S): Histologic evaluation of chorionic villi from ectopic pregnancies was done by two pathologists who were unaware of the cytogenetic outcome. Seventeen histologic features were evaluated: villus size, villus contour, ghost villi, hydropic villi, trophoblastic hyperplasia, trophoblastic hypoplasia, syncytial knots, Hofbauer cells, blood vessels, trophoblastic lacunae, trophoblastic inclusions or cisterns, degeneration, fibrohyalinization, microcalcifications, and perivillous and intervillous fibrin deposits. MAIN OUTCOME MEASURE(S): The association between histopathologic features and cytogenetic outcome. RESULT(S): The presence of ghost villi and intervillous or perivillous fibrin was found to be associated with cytogenetic abnormalities. These features are associated with previous fetal cell death. CONCLUSION(S): This study does not support an association between specific histologic features of chorionic villi and cytogenetic abnormalities in ectopic pregnancies. The only histologic features that were associated with cytogenetic abnormalities (i.e., ghost villi and intervillous and perivillous fibrin) are merely a result of previous fetal cell death.

Predictors of treatment failure for ectopic pregnancy treated with single-dose methotrexate.

OBJECTIVE: To determine variables that predict treatment failure after methotrexate (MTX) treatment of ectopic pregnancy. DESIGN: Retrospective cohort study. SETTING: Canadian teaching hospital. PATIENT(S): Sixty patients diagnosed with and treated for ectopic pregnancy. INTERVENTION(S): A single dose of methotrexate (50 mg/m(2)) by i.m. injection. MAIN OUTCOME MEASURE(S): Resolution of serum beta-hCG or clinical evidence of treatment failure. RESULT(S): Treatment failure was observed following methotrexate administration in 65% of cases when initial beta-hCG was >4000 IU/L, but in only 7. 5% of patients when serum beta-hCG was <4000 IU/L (OR = 52.06, 95% CI 4.88-555.56). Patients who presented with pelvic pain without tenderness had treatment failure 56% of the time versus only 17% in those without pain (OR = 9.20, 95% CI 1.02-82.60). Treatment failure also occurred in 53% of patients presenting with vaginal bleeding versus 16% without bleeding (OR = 6.18, 95% CI 0.73-51.93). CONCLUSION(S): Methotrexate should not be used to treat ectopic pregnancy when initial beta-hCG is >4000 IU/L. Caution should also be exercised in using methotrexate for ectopic pregnancy when the patient presents with bleeding or pain even without tenderness.

Human chorionic gonadotropin level as a predictor of trophoblastic infiltration into the tubal wall in ectopic pregnancy: a blinded study.

OBJECTIVE: To determine the relationship between gestational age, tubal ultrasonographic diameter, and serum hCG levels and different stages of trophoblastic infiltration of the tubal wall in ectopic pregnancy. DESIGN: Blinded prospective study. SETTING: University-based clinic in Italy. PATIENT(S): Thirty-seven consecutive patients with an ampullary ectopic pregnancy. INTERVENTION(S): Laparoscopic salpingectomy. MAIN OUTCOME MEASURE(S): Gestational age, diameter of the tubal mass as determined by transvaginal ultrasonography. and hCG level on the day of surgery. Ectopic pregnancy was classified according to the depth of trophoblastic infiltration: trophoblast limited to the tubal mucosa (stage I), extension to the tubal muscularis (stage II), or complete tubal wall infiltration up to the serosa discontinued by trophoblastic cells (stage III). RESULT(S): Fifteen patients (40.5%) had stage I tubal infiltration, 14 (37.8%) had stage II infiltration, and 8 (21.6%) had stage III infiltration. Gestational age and diameter of the tube did not differ among the three groups. The median hCG level was 1,710.5 mIU/mL (range, 113-5,635 mIU/mL) for patients with stage I infiltration. 4,690.0 mIU/mL (range, 150-21,531 mIU/mL) for patients with stage II infiltration, and 15,700.0 mIU/mL (range, 13,809-21,650 mIU/mL) for patients with stage III infiltration. All the patients with hCG levels > 6,000 mIU/mL had stage II or III invasion. CONCLUSION(S): These findings may explain why the conservative treatment of ectopic pregnancy is less successful in patients with high hCG levels than in patients with low levels. Use of radical procedures may be justified in the former group.

The use of a radioreceptorassay of human chorionic gonadotropin for the diagnosis and management of ectopic pregnancy.

The radioreceptorassay of human chorionic gonadotropin (hCG), with a sensitivity of 50 pg or 3 mIU/ml of plasma, has provided almost 100% reliability in detecting pregnancy after the first missed cycle. This test may be performed within 1 hour and is ideally suited to the clinical detection of ectopic pregnancy, especially in patients who require immediate surgical intervention. Thirteen patients with suspected ectopic pregnancy were evaluated by the radioreceptorassay, one of whom was followed with four separate determinations. The results of the assay were subsequently compared with those of hemagglutination pregnancy tests, clinical symptoms, and pathologic findings. All of the patients were diagnosed accurately by the radioreceptorassay, even when hemagglutination tests yielded a false indication of pregnancy. By this assay, the hCG levels during ectopic pregnancies are generally lower than those found during a normal intrauterine pregnancy; in addition, pregnancy may be detected much earlier (prior to the rupture) than is possible by hemagglutination tests. Furthermore, the diagnosis of ectopic pregnancy may be excluded for patients admitted to the hospital with acute abdominal emergencies.

Improved fertility following ectopic pregnancy.

The reproductive performance subsequent to operative removal of ectopic pregnancy was examined in 154 women. They represent 64% of 242 women admitted for ectopic pregnancy between 1969 and 1979. The follow-up period averaged 4.2 years. The patients at risk had a conception rate of 81%, with a repeat ectopic pregnancy incidence of 7.8%, and 65% had at least one live birth. Postoperative infertility was significantly associated with (1) previous sterility, (2) coexistent periadnexal adhesions and/or tubual disease, (3) rupture of the ectopic pregnancy, and (4) older age. A statistically significant advantage of conservative over radical treatment, as regards future fertility, was demonstrated only in 53 patients with either history or findings suggestive of previously impaired fertility. Early, prerupture diagnosis and treatment, coupled with conservative and restorative measures, might account for the improved reproductive performance.

Receiver operating characteristic (ROC) curve analysis of the relative efficacy of single and serial chorionic gonadotropin determinations in the early diagnosis of ectopic pregnancy.

A study was undertaken of 36 patients with viable intrauterine pregnancies who presented in the first trimester with abdominal pain and/or vaginal bleeding, and of 15 patients with ectopic pregnancies, all of whom had at least two human chorionic gonadotropin (hCG) determinations in the same gestation. The mean and lower 25%, 20%, 15%, 5%, and 1% limits of the rate of hCG increase in serum and of the serum hCG at different periods of gestation were determined for intrauterine pregnancy with the use of linear regression analysis, and each was used as a basis for identifying ectopic gestation. It was found that for any given false-positive rate, subnormal rates of hCG increase were more sensitive in identifying ectopic gestations than single "low for date" hCG values. It is suggested that the explanation for this may be that hCG production in many patients with ectopic pregnancies is normal until symptoms develop and falls thereafter as the functional trophoblastic mass is reduced by the shearing off the trophoblast from the tubal wall, which takes place with the development of the pregnancy and of symptoms.

The role of tubal pathology and other parameters in ectopic pregnancies occurring in in vitro fertilization and embryo transfer.

Contradictory findings were reported concerning the role of tubal disease in the genesis of ectopic pregnancy in in vitro fertilization and embryo transfer (IVF-ET). We report on six ectopics that occurred in 141 IVF-ET pregnancies (4.3%). All of the six cases were among 84 patients with tubal disease, and none occurred in the remaining 57 patients with other etiological factors. No correlation was found in other parameters including: ovulation induction, number of embryos transferred, and luteal support. A comparison between the ectopics and six matched controls demonstrated similar estradiol levels, but beta-hCG levels on day 15 to 17 after ET were lower. Homolateral salpingectomy was performed in all six cases, but a contralateral resection was carried out in three of them. More comprehensive studies are needed to clarify whether tubal pathology really increases the risk for ectopic gestation in IVF-ET.

Fertility after ectopic pregnancy in relation to background factors and surgical treatment.

To study the importance of certain background factors and surgical treatment, the obstetric outcome in 205 women consecutively treated for ectopic pregnancy was analyzed by means of questionnaires 4 to 5.5 years after surgery. The response rate was 83.4% and, among women desiring pregnancy (n = 112), the total pregnancy rate was 75.9% and the delivery rate 53.6%. The total incidence of repeat ectopics was 27.3%, and the proportion of women who had a repeat ectopic pregnancy but no delivery was 20.5%. Six of seven women having an ectopic pregnancy with a copper intrauterine contraceptive device in situ had a normal delivery during the follow-up period. The subsequent fertility among nonresponders appeared lower than among responding women. A number of background factors present at the time of surgery were correlated to subsequent infertility, e.g., history of infertility and previous abdominal surgery. Conversely, there was no correlation between the fertility outcome and the type of operative procedure.
