RESUMO

RESUMEN Introducción: El embarazo ectópico es toda gestación, en la que el sitio de implantación del óvulo fecundado se localiza fuera de la cavidad endometria y representa el 1.4 % de estos. Caso clínico: Paciente de 28 años con dos cesáreas previas, sometida a salpingoclasia durante la última intervención. La paciente ingresó al hospital con presión arterial de 180/130 mm Hg, no respondió a tratamiento médico y presentó falla en la progresión de trabajo de parto, por lo que se decidió interrupción por operación cesárea. Durante la cirugía, se observó un pequeño útero con embarazo extrauterino adherido a la serosa del ciego, el colon ascendente y el apéndice. Se obtuvo un producto femenino pretérmino vivo; la madre cursó con evolución favorable y sin complicaciones posoperatorias. Conclusión: La presentación del embarazo abdominal ectópico es rara, por lo que un control prenatal adecuado por personal capacitado puede orientar a la sospecha diagnóstica. La madre y la recién nacida no presentaron ninguna complicación, a pesar de ser un embarazo abdominal avanzado y la inserción multifocal de la placenta. Se resalta la importancia del manejo oportuno y multidisciplinario cuando se enfrentan embarazos con curso anormal para la mejor evolución de la madre y del producto.

ABSTRACT Introduction: Ectopic pregnancy is any gestation in which the implantation site of the fertilized egg is located outside the endometrial cavity. Abdominal ectopic pregnancy represents 1.4% of these. Case report: 28-year-old patient with two previous cesarean sections; bilateral tubal obstruction during the last operation. The patient was admitted to the hospital with blood pressure of 180/130 mm Hg that did not respond to medical treatment and not progression to labor so it was decided to interrupt the pregnancy by cesarean section. During surgery, a small uterus with extrauterine pregnancy was observed adhered to the serosa of the cecum, ascending colon, and appendix. A live preterm female product was obtained; the mother had a favorable evolution and no postoperative complications. Conclusion: Ectopic pregnancies are rera. An adequate prenatal control by well trained personnel is essential for an accurate diagnosis. The mother and the newborn did not present any complication. It is very important to have and accurate an opportune diagnosis so trained personnel can offer an adequate management.

RESUMO

Abdominal pregnancy is defined as one that occurs outside of the uterus and fallopian tubes in the abdominal cavity. We present the case of a 30-year-old Peruvian female patient from Lima with a surgical history of exploratory laparotomy due to tubal ectopic pregnancy and appendectomy without further relevant personal or family histories. She attended the emergency room of a social security hospital in Peru with a referral from a district hospital and a diagnosis of abdominal pregnancy at 14 weeks of gestational age without previous prenatal controls. Symptomatology at hospital admission was colic-type abdominal pain in the hypogastrium without vaginal bleeding, fluid loss or fever. During hospitalization, she underwent an exploratory laparotomy with embolization of the uterine artery, left salpingectomy, and removal of the abdominal ectopic pregnancy. The evolution was favorable after the surgery, and she was discharged. Without further complications, she continues her controls at the obstetrics and gynecology outpatient service without complications.

El embarazo abdominal es aquel embarazo que ocurre fuera del útero y las trompas de Falopio en la cavidad abdominal. Presentamos el caso de una paciente peruana de 30 años proveniente de la ciudad de Lima, con antecedentes quirúrgicos de laparotomía exploradora por embarazo ectópico tubárico y apendicectomía, sin otras patologías ni antecedentes familiares de importancia. La paciente acude al servicio de urgencias de un hospital del seguro social en Perú derivada de un hospital distrital con diagnóstico de embarazo abdominal a las 14 semanas de edad gestacional, sin controles prenatales previos. La sintomatología al ingreso hospitalario fue dolor abdominal de tipo cólico a nivel del hipogastrio, sin sangrado vaginal, pérdida de líquidos o fiebre. Durante su hospitalización se le realizó una laparotomía exploratoria con embolización de la arteria uterina, salpingectomía izquierda y extracción del embarazo abdominal. La evolución fue favorable tras la intervención quirúrgica, siendo dada de alta. Actualmente continúa sus controles en el servicio de consulta externa del servicio de ginecología y obstetricia sin complicaciones.

RESUMO

ABSTRACT OBJECTIVE To assess the effect of attending antenatal classes on fear of childbirth and antenatal stress in nulliparous pregnant women. METHODS A total of 133 nulliparous pregnant women participated in the study, which had a quasi-experimental design. Data were collected by a descriptive data form, the Wijma Delivery Expectancy/Experience Questionnaire, and the Antenatal Perceived Stress Inventory (APSI). RESULTS A significant correlation was found between antenatal class attendance and having a high schooling level and an intended pregnancy (p < 0.05). The mean fear of childbirth score of pregnant women was 85.50 ± 19.41 before the training and 76.32 ± 20.52 after the training, and the difference between these scores was significant (p < 0.01). Fear of childbirth score were not significantly different between the intervention group and the control group. The mean APSI score of pregnant women in the intervention group was 22.32 ± 6.12 before the training and 21.79 ± 5.97 after the training. However, this difference was not statistically significant (p = 0.70). CONCLUSION The fear of childbirth score decreased significantly in the intervention group after the training.

RESUMO

El embarazo ectópico abdominal es una patología poco frecuente, la cual consiste en un embarazo con implantación dentro de la cavidad abdominal y fuera del útero y sus anexos; siendo el menos frecuente de los embarazos ectópicos, y representando el 1 % de los casos. Sin embargo, cuando se presenta, la tasa de mortalidad materno-fetal es alta, por lo que representa una urgencia médica con complicaciones graves como hemorragia obstétrica. El diagnóstico requiere un alto grado de sospecha, debido a que el sangrado menstrual regular puede estar presente. Se presenta el caso de una paciente primigestante con embarazo ectópico abdominal en segundo trimestre, con manejo definitivo quirúrgico y posterior evolución materna favorable al postquirúrgico, sin embargo, con resultado perinatal adverso para el recién nacido. La importancia de este caso radica en su diagnóstico oportuno, por el cual se logró evitar complicaciones que pusieran en riesgo la vida de la paciente.

Abdominal ectopic pregnancy is a rare pathology, it is expressed by a pregnancy with implantation inside the abdominal cavity and outside the uterus and its annexes, being specifically the least frequent of ectopic pregnancies, representing 1% of cases. When it occurs, the maternal-fetal mortality rate is high1. The diagnosis requires a high degree of suspicion, due to regular menstrual bleeding may be present. It is a medical emergency with serious complications such as obstetric hemorrhage. We present the case of a prime pregnant patient with abdominal ectopic pregnancy in the second trimester with definitive surgical management, and subsequent maternal evolution favorable to post-surgery, however, with adverse perinatal outcome for the newborn. The importance of this case lies in its timely diagnosis, by which it was possible to avoid complications that put the patient's life at risk.

RESUMO

Abdominal ectopic pregnancy (AEP) occurs within the peritoneal cavity, outside the genital organs (uterus, tubes, ovaries). It is an unusual condition with an incidence that varies from 1:10,000 to 1:30,000 of all pregnancies worldwide. A 38-year-old primigravid patient was diagnosed in the second trimester with AEP. Pregnancy reached 35.6 gestational weeks, and the patient underwent surgery via laparotomy for extraction of the live fetus. Complete removal of the placenta was performed without maternal or fetal complications. AEP is an important cause of maternal and fetal death; the mortality rate in pregnant women with AEP is approximately 1-18%. Surgical intervention to deliver a baby in cases of AEP requires a multidisciplinary team, especially in countries with limited therapeutic options.

Abstract We present the clinical case of a 36-year-old female patient, treated at the Hospital Japonés (HJ) in the city of Santa Cruz, who was admitted to our hospital with a clinical presentation of acute abdomen and a 20-week pregnancy, with a relevant history of abortion due to an ectopic pregnancy three years ago, Exploratory laparotomy was performed in which abdominal pregnancy was evidenced, the fetus and placenta were extracted, packing was placed and left in contained laparotomy, after 72 hours cleaning and closure of the abdominal wall was performed, patient with good clinical evolution.

RESUMO

Resumen ANTECEDENTES: El embarazo abdominal representa el 1% de los embarazos ectópicos, con una mortalidad materna que puede alcanzar, incluso, hasta el 20% y una mortalidad fetal hasta del 90%. CASO CLÍNICO: Paciente de 31 años, en curso de las 39 semanas del segundo embarazo. El primero se atendió, sin complicaciones, en el domicilio cuando tenía 25 años; enseguida se le indicó, como método anticonceptivo, acetato de medroxiprogesterona inyectable trimestral. Acudió al Hospital Regional Docente de Cajamarca debido a un dolor abdominal luego de siete controles prenatales. Se ingresó al servicio de Obstetricia al tercer día con pródromos de labor de parto, feto en transverso y placenta previa. En la cesárea de urgencia el útero se encontró de 18 cm, la placenta adherida al epiplón, intestino, colon sigmoide, recto y pared izquierda del útero. Se obtuvo una recién nacida con Apgar 8-9, sin malformaciones. Se practicaron: extracción de la placenta, histerectomía abdominal subtotal y salpingooforectomía izquierda. El sangrado intraoperatorio fue de 1800 mL por lo que ameritó la transfusión de dos paquetes globulares. La madre y su hija evolucionaron favorablemente por lo que se dieron de alta del hospital, sin complicaciones. CONCLUSIÓN: El embarazo abdominal es un evento raro, sobre todo si llega a término y con un recién nacido vivo saludable. A pesar de los estudios ultrasonográficos, el embarazo abdominal no es de diagnóstico fácil; por eso casi todos se diagnostican durante la cirugía. Si la placenta no afecta estructuras vasculares extensas, ni órganos abdominopélvicos, podrá retirse, con cuidados extremos, para no originar males mayores.

Abstract BACKGROUND: Abdominal pregnancy represents 1% of ectopic pregnancies, with a maternal mortality that can reach up to 20% and a fetal mortality of up to 90%. CLINICAL CASE: 31-year-old female patient, in the course of 39 weeks of her second pregnancy. The first pregnancy was attended, without complications, at home when she was 25 years old; she was immediately prescribed quarterly injectable medroxyprogesterone acetate as a contraceptive method. She went to the Regional Teaching Hospital of Cajamarca due to abdominal pain after seven prenatal check-ups. She was admitted to the obstetrics service on the third day with prodromes of labor, transverse fetus and placenta previa. In the emergency cesarean section the uterus was found to be 18 cm, the placenta adhered to the omentum, intestine, sigmoid colon, rectum and left wall of the uterus. A newborn was obtained with Apgar 8-9, without malformations. Placental extraction, subtotal abdominal hysterectomy and left salpingo-oophorectomy were performed. Intraoperative bleeding was 1800 mL, which required the transfusion of two packs of red blood cells. The mother and daughter evolved favorably and were discharged from the hospital without complications. CONCLUSION: Abdominal pregnancy is a rare event, especially if it is carried to term with a healthy live newborn. Despite ultrasonographic studies, abdominal pregnancy is not easily diagnosed; therefore almost all are diagnosed during surgery. If the placenta does not affect extensive vascular structures or abdominopelvic organs, it can be removed, with extreme care, so as not to cause greater harm.

RESUMO

RESUMEN Presentamos dos casos de embarazo ectópico abdominal de 16 y 26 semanas, evaluados con ecografía y resonancia magnética. Ambos casos ingresaron con cuadro de abdomen agudo quirúrgico, el de mayor edad gestacional con descompensación hemodinámica por hemoperitoneo secundario a desprendimiento placentario. La presentación clínica conllevó a la resolución por laparotomía y extracción del feto y del tejido placentario, terminando el primer caso en histerectomía por compromiso trofoblástico de la superficie uterina y órganos adyacentes. El neonato de 26 semanas falleció luego de 4 meses, por sepsis tardía. La sospecha clínica por amenorrea y dolor abdominal intenso son criterios importantes, y los estudios de imágenes, especialmente la ecografía transvaginal y pélvica, son las principales herramientas diagnósticas.

ABSTRACT We present two cases of abdominal ectopic pregnancy of 16 and 26 weeks, evaluated with ultrasound and magnetic resonance imaging. Both cases presented an acute surgical abdomen, the case with the oldest gestational age showed hemodynamic decompensation due to hemoperitoneum secondary to placental abruption. The clinical presentation led to resolution by laparotomy and extraction of the fetus and placental tissue, ending in hysterectomy due to trophoblastic involvement of the uterine surface and adjacent organs in the first case. The 26-week-neonate died after 4 months due to late sepsis. Clinical suspicion for amenorrhea and severe abdominal pain are important criteria, and imaging studies, especially ultrasound, are the main diagnostic tools.

RESUMO

Introducción: el embarazo ectópico se produce cuando el embrión se implanta fuera de la cavidad uterina, y se ubica mayormente en las trompas de Falopio. Objetivo: presentar un caso clínico en el que la paciente desarrolló un embarazo ectópico en la cicatriz de una histerorrafia previa, fue diagnosticada cuando cursaba la sexta semana de gestación y se resistió ante la idea de perderlo irremediablemente, aunque su cuadro clínico es muy doloroso y se complica rápidamente. Presentación del caso: paciente de 27 años de edad, de color de piel negra, con antecedente de cesárea previa 9 meses atrás. Según reporte ecográfico se diagnostica embarazo de 8,6 semanas de gestación localizado en la zona de cicatriz de cesárea previa. Recibe tratamiento inicial con metotrexate y cloruro de potasio, para luego ser intervenida quirúrgicamente a través de legrado instrumental, se corrobora diagnóstico ecográfico y se logra extraer el embrión exitosamente. Conclusión: el manejo atendió a las características clínicas e individuales de la gestante y se respetó el principio de autonomía de la embarazada. La paciente pudo ser dada de alta con un estado de salud satisfactorio, conservó su capacidad de fecundidad(AU)

Introduction: Ectopic pregnancy occurs when the embryo is implanted outside the uterine cavity, mostly located in the fallopian tubes. Objective: To present a clinical case in which the patient developed an ectopic pregnancy over a previous cesarean section scar; the diagnosis was made when she was in the sixth week of her pregnancy and she could not withstand the idea of losing the baby, but the clinical picture worsened, she was very painful and became complicated quickly. Case report: Twenty-seven-year-old black patient with previous history of a cesarean section 9 months ago. According to ultrasound criteria, 8.6 weeks of pregnancy located in the area of a previous cesarean section scar is diagnosed. The patient receives initial treatment with methotrexate and potassium chloride to undergo a surgical procedure through instrumental intervention (curettage), confirming the diagnosis of the ultrasound and removing the embryo successfully. Conclusions: The management was based on the clinical and individual characteristics of the pregnant woman respecting the principle of autonomy. The patient was in good health at the moment of discharge, preserving her fertility capacity(AU)

RESUMO

ANTECEDENTES El embarazo ectópico abdominal es el menos habitual de los embarazos ectópicos, con una prevalencia situada entre el 0.9 - 1.4%. La mortalidad materna es elevada, alcanzando un 20% y la viabilidad fetal mínima. El manejo médico en estas situaciones es complicado ya que no está bien establecido debido a su baja frecuencia. CASO CLÍNICO Mujer de 35 años, con antecedente de esterilidad por endometriosis y salpinguectomía bilateral. Tras 5 fecundaciones in vitro (FIV) consigue una primera gestación, con finalización mediante cesárea por no progresión de parto. Acude a urgencias en su segundo embarazo, logrado tras 3 (FIV), con edad gestacional de 7 semanas. Presenta sangrado vaginal escaso y la ecografía demuestra a nivel de Douglas y hacia fosa iliaca izquierda un saco gestacional de 3 cm con embrión sin latido cardiaco de 5 mm. El nivel de β-hcg es de 1477 mUI/ml. Se diagnostica de gestación ectópica abdominal y se opta por actitud expectante dada la estabilidad clínica de la paciente. En un control a las 48h la β-Hcg es de 464 mUI/ml y la paciente se mantiene estable. En controles posteriores se observan niveles descendentes de β-Hcg y tras un mes la resolución es completa. CONCLUSIÓN El embarazo ectópico abdominal es una entidad poco frecuente pero con una alta tasa de mortalidad. Aunque lo más común es optar por un abordaje quirúrgico es necesario individualizar cada caso y basarse en la clínica y las diferentes pruebas diagnósticas para seleccionar aquellos casos que se pueden beneficiar de un manejo conservador.

BACKGROUND Abdominal ectopic pregnancy accounts for only 0.9-1.4% of all ectopic pregnancies. The maternal mortality rate is high (up to 20%) and fetal viability mínimum. The managment, specially the conservatory management of these cases is difficult because of our limited experiencie due to its low frecuency. CASE PRESENTATION 35-year-old woman, with history of sterility due to endometriosis that required bilateral laparoscopic salpinguectomy. Her first pregnancy (after 5 in vitro fertilization cicles (IVF)) finalized with a caesarean section because of to the lack of labour progresion. She was admitted to our emergency department during her second pregnancy (after 3 IVF cicles), with 7 weeks of gestational age. She had a little vaginal bleeding. Ultrasound scan showed a 5mm gestational sac with a 3mm embryo without cardiac activity in the pouch of Douglas. The β-Hcg level was 1477mUI/ml. The final diagnosis was ectopic abdominal pregnancy and it was decided to undertake an expectant management because she was clinically stable. The β-Hcg level after 48 hours was 464 mUI/ml. In subsequent examinations β-Hcg showed descending levels and after one month the resolution was completed. CONCLUSION Abdominal ectopic pregnancy is very infrequent but it has a high mortality rate. The most common approach is surgical but it is necessary to study all signs and diagnostic tests to select patients that could get profit from a conservatory management.

RESUMO

Abdominal ectopic pregnancy is a dramatic situation for the woman's health. It is a rare pathology that proves to be a difficult test even for the most experienced gynecologists in diagnostic ability, decision-making and surgical technique. We present the case of a hospitalized post-term ectopic abdominal pregnancy with a dead fetus inside the chorioamniotic sac and the placenta implanted on vital abdominal viscera. We describe the clinical data, operative findings and conservative management of the retained placenta, followed by a bibliographic review on the subject.

El embarazo ectópico abdominal representa una situación dramática para la salud de la mujer. Al ser una patología poco frecuente, resulta al ginecólogo una prueba difícil para habilidad diagnóstica, capacidad de decisión y técnica quirúrgica, incluso para el más experto. Se presenta un caso de embarazo ectópico abdominal postérmino, que llegó con óbito fetal dentro de la bolsa corioamniótica y la placenta implantada sobre vísceras abdominales. Se describe los datos clínicos, hallazgos operatorios y el manejo conservador de la placenta retenida, y se hace una revisión bibliográfica del tema.

RESUMO

Abstract Ectopic pregnancy is the leading cause of pregnancy-related death during the first trimester, and it occurs in 1 to 2% of pregnancies. Over 90% of ectopic pregnancies are located in the fallopian tube. Abdominal pregnancy refers to an ectopic pregnancy that has implanted in the peritoneal cavity, external to the uterine cavity and fallopian tubes. The estimated incidence is 1 per 10,000 births and 1.4%of ectopic pregnancies. Lithopedion is a rare type of ectopic pregnancy, and it occurs when the fetus from an unrecognized abdominal pregnancymay die and calcify. The resulting "stone baby" may not be detected for decades andmay cause a variety of complications. Lithopedion is a very rare event that occurs in 0.0054% of all gestations. About 1.5 to 1.8% of the abdominal babies develop into lithopedion. There are only ~ 330 known cases of lithopedion in the world. We describe a lithopedion that complicated as intestinal obstruction in a 71-year-old woman.

Resumo A gravidez ectópica é a principal causa de morte materna no primeiro trimestre, e ocorre em 1 a 2% das gestações. Mais de 90% ocorrem nas tubas uterinas. Gravidez abdominal refere-se à gravidez ectópica implantada na cavidade peritoneal, externamente ao útero e às tubas uterinas.Aincidência estimada éde 1 por 10mil nascimentos e 1,4%das gravidezes ectópicas. A litopedia é um tipo raro de gravidez ectópica, e ocorre quando o feto de uma gravidez abdominal não reconhecida morre e se calcifica. O "bebê de pedra" resultante pode não ser detectado por décadas, e pode causar complicações futuras. A litopedia é um evento muito raro que ocorre em 0,0054% de todas as gestações. Cerca de 1,5 a 1,8% dos bebês abdominais se tornam litopédios. Existem somente cerca de 330 casos conhecidos de litopedia no mundo. Descrevemos uma litopedia que se agravou, tornando-se uma obstrução intestinal, em uma idosa de 71 anos.

RESUMO

Resumen ANTECEDENTES: El embarazo ectópico abdominal es una alteración poco frecuente, pero con alta tasa de morbilidad y mortalidad materno-fetal-neonatal. Para establecer el diagnóstico se requiere un alto grado de sospecha y casi siempre se efectúa durante el procedimiento quirúrgico. Es el único tipo de embarazo ectópico que puede llegar a término. CASO CLÍNICO: Paciente de 35 años, con antecedente obstétrico de dos cesáreas, que acudió al servicio médico por dolor abdominal de larga evolución, con varios meses de amenorrea, sin control prenatal. El dolor fue inicialmente adjudicado a una hernia umbilical, pero ante su persistencia se reexaminó a la paciente y se encontró una masa abdominal, por lo que se sospechó embrazo ectópico. El ultrasonido abdominal y la resonancia magnética confirmaron el embarazo de término, que finalizó mediante laparotomía. Se decidió dejar la placenta in situ, debido al riesgo de hemorragia por su remoción. Tanto el neonato como la madre fueron dados de alta en buenas condiciones después de dos semanas de estancia hospitalaria, con posterior seguimiento. CONCLUSIONES: Aunque el embarazo ectópico abdominal es una alteración poco frecuente, es importante saber qué debe hacerse de acuerdo con las semanas de gestación, debido al incremento reciente en su incidencia y a la alta tasa de complicaciones, con la finalidad de preservar el bienestar materno-fetal y la fertilidad femenina.

Abstract BACKGROUND: Abdominal pregnancy is a rare clinical entity with a high risk for both the mother and the product. It's diagnosis requires a high level of suspicion, being usually made during the surgical management of the case. It is the only type of ectopic pregnancy that can reach term. CLINICAL CASE: A 35 year-old patient, with two previous cesarean deliveries, who presents with chronic abdominal pain, without prenatal consultations and with several months of amenorrhea. The pain is initially atributted to an umbilical hernia, but due to it's persistence she is re-examined, finding an abdominal mass and raising suspicion of a possible ectopic pregnancy. She's sent to a hospital in western Mexico, where she undergoes abdominal examination with ultrasound and magnetic resonance, which shows a full term abdominal pregnancy, for which a laparotomy is performed. The placenta is left in situ, due to the high risk of hemorrhage associated with it's removal. Both the newborn and the mother are released from the hospital in good conditions after two weeks of stay, with subsequent follow-up. CONCLUSIONS: Despite it being a rare condition, it's important to be acquainted with the proper management according to the gestational age of the pregnancy due to the recent rise in it's incidence, as well as it's particularly high rate of complicactions, in order to preserve the wellbeing of both patients when possible, as well as maternal fertility.

RESUMO

Resumen Antecedentes: El embarazo ectópico abdominal es una alteración obstétrica poco frecuente, sobre todo en pacientes con antecedente de histerectomía. Los síntomas suelen ser inespecíficos y el diagnóstico se retrasa por la baja sospecha clínica, con el subsiguiente aumento en la morbilidad y mortalidad materna. Caso Clínico: Paciente de 33 años, con antecedentes ginecoobstétricos de tres cesáreas e histerectomía subtotal posparto por placenta acreta, que acudió al servicio médico por dolor abdominal y sangrado vaginal. En la ecografía se visualizó el saco gestacional con embrión de 12 + 4 semanas y latido cardiaco positivo. Se indicó laparotomía urgente por abdomen agudo y sospecha de embarazo ectópico abdominal; durante el procedimiento se evidenció el saco gestacional de 7 cm, adherido al colon sigmoide y al remanente cervical, con rotura sangrante hacia la cavidad abdominal que englobaba el anejo izquierdo. Se practicó resección del embarazo ectópico y anexectomía izquierda, en colaboración con el servicio de Cirugía general. El posoperatorio transcurrió sin incidentes y la paciente fue dada de alta satisfactoriamente. Conclusiones: Es importante incluir el embarazo ectópico en el diagnóstico diferencial de abdomen agudo, incluso en pacientes con antecedente de histerectomía.

Abstract Background: Abdominal ectopic pregnancy is a rare condition in obstetrics, especially if there is a history of hysterectomy. Symptoms are usually nonspecific and the diagnosis is often delayed by low clinical suspicion, with consequent increase in maternal morbi-mortality. Clinical case: 33 year-old patient with 3 previous cesareans and subtotal hysterectomy postpartum for placenta accreta, referred by abdominal pain and vaginal bleeding. In the gynecological ultrasound, a gestational sac was visualized with an embryo according to 12 + 4 weeks, with positive heartbeat. Urgent laparotomy was indicated for acute abdomen and suspicion of abdominal ectopic pregnancy, showing a gestational sac of 7 centimeters adhered to sigma and cervical stump with a bleeding broken zone to abdominal cavity that enclosed left annex, reason why resection of ectopic gestation and left annexectomy was performed in collaboration with General Surgery Service. The postoperative period was without consequences and the patient was satisfactorily discharged. Conclusions: It is important to include this entity within the differential diagnosis of acute abdomen women of childbearing age, even if a previous hysterectomy has been performed.

RESUMO

Background: Ectopic pregnancy mainly refers to tubal pregnancy and abdominal pregnancy. Tubal pregnancy presents as an implanted embryo that develops in the fallopian tubes, and is relatively common in humans. In animals, tubal pregnancy occurs primarily in primates, for example monkeys. The probability of a tubal pregnancy in non-primate animals is extremely low. Abdominal pregnancy is a type of ectopic pregnancy that occurs outside of the uterus, fallopian tube, ovary, and ligament (broad ligament, ovarian ligament, suspensory ligament).This paper describes two cases of ectopic pregnancy in cats.Cases: Cat 1. The presenting sign was a significant increase in abdominal circumference. The age and immune and sterilization status of the cat were unknown. On palpation, a 4 cm, rough, oval-shaped, hard mass was found in the posterior abdomen. Radiographic examination showed three high-density images in the posterior abdomen. The fetus was significantly calcified and some feces was evident in the colon. The condition was preliminarily diagnosed as ectopic pregnancy. Cat 2. The owner of a 2-year-old British shorthair cat visited us because of a hard lump in the cats abdomen. The cat had a normal diet and was drinking normally. Routine immunization and insect repulsion had been implemented. The cat had naturally delivered five healthy kittens two months previous. Radiographs showed an oval-shaped mass with a clear edge in the middle abdominal cavity. Other examinations were normal. The case was preliminarily diagnosed as ectopic pregnancy, and the pregnancy was surgically terminated. The ectopic pregnancies were surgically terminated. During surgery, the structures of the uterus and ovary of cat 1 were found to be intact and the organs were in a normal physiological position. Cat 1 was diagnosed with primary abdominal pregnancy. In cat 2, the uterus left side was small and the fallopian tube on the same side was both enlarged and longer than normal.[...](AU)

RESUMO

Secondary abdominal ectopic pregnancy is rare in clinical practice, but may lead to an increased maternal mortality. We present the case of a patient with an abdominal pregnancy secondary to a uterine perforation caused by a voluntary attempt to interrupt pregnancy that presented with nine weeks of abdominal pain and minimal vaginal bleeding which was mistakenly diagnosed as acute pelvic inflammatory disease, urinary tract infection, and post-abortion products of conception. Finally, the abdominal ultrasound test found an abdominal ectopic pregnancy. An exploratory laparotomy was performed and the fetus and placenta were removed without difficulties with a favorable postoperative course. It was concluded that uterine perforation during curettage of the cavity went unnoticed, leading to secondary abdominal implantation of pregnancy with a inconclusive clinical presentation, where ultrasound plays a fundamental diagnostic role. Laparotomy is indicated in most of these cases.

El embarazo ectópico abdominal secundario tiene una baja frecuencia de presentación en la práctica clínica, pero puede llevar al incremento de la mortalidad materna. Se presenta el caso de una paciente con embarazo abdominal secundario a una perforación uterina, causada por una interrupción voluntaria del embarazo. Este evolucionó durante nueve semanas con dolor abdominal y sangramiento vaginal escaso. A la paciente se le realizaron diagnósticos como enfermedad inflamatoria pélvica aguda, infección del tracto urinario, restos ovulares post aborto y definitivamente se concluyó como embarazo ectópico abdominal mediante ecografía abdominal. Se le realizó laparotomía exploradora y se extrajo el feto y la placenta sin dificultades con una evolución postoperatoria favorable hacia la curación. Se concluyó que la perforación uterina durante el curetaje de la cavidad pudo pasar inadvertida, llevando a implantación abdominal secundaria del embarazo con un cuadro clínico variable. En dicho cuadro, el ultrasonido juega un papel fundamental para su diagnóstico, siendo el manejo laparotómico el más apropiado en estos casos.

RESUMO

RESUMEN Objetivo: Reportar dos casos de embarazo ectópico abdominal avanzado, con buen resultado materno / perinatal, y revisar la literatura disponible con respecto al manejo de la placenta y el pronóstico de esta entidad. Materiales y métodos: Se describen dos casos de embarazo ectópico abdominal avanzado en los que se realizó extracción de la placenta, con feto viable y resultado perinatal favorable. Estos fueron atendidos en una institución de cuarto nivel de complejidad,ubicada en la ciudad de Cali, Colombia. Se realizó una revisión de la literatura registrada en las bases de datos Medline vía PubMed, con los términos de búsqueda: "embarazo abdominal", "embarazo esplénico", "embarazo hepático", "embarazo omental" y "embarazo peritoneal". La búsqueda se limitó a artículos publicados durante los últimos doce años en inglés y español. Resultados: Se recuperaron 228 referencias, de las cuales 42 artículos cumplieron con los criterios de inclusión que informan un total de 74 pacientes con embarazo ectópico abdominal. En cuanto al manejo de la placenta, la remoción de la misma se informó en 42 casos (58%). La mortalidad materna se presentó en 4 casos (4,1%), todos por hemorragia posparto. Un total de 60 pacientes (81%) presentaron complicaciones, la más frecuente fue hemorragia en 38 de ellas (51%). En cuanto al resultado perinatal, se encontró una mortalidad perinatal del 43%. Conclusión: El manejo de la placenta es el punto clave del que podría depender la frecuencia de complicaciones maternas. Se requieren estudios prospectivos que evalúen el manejo más seguro y efectivo de esta condición.

ABSTRACT Objective: Report two cases of advanced ectopic abdominal pregnancy with good maternal/perinatal outcomes, and to review the literature available regarding the management of the placenta and the prognosis for this condition. Materials and methods: Description of two cases of advanced ectopic abdominal pregnancies with viable fetuses and favourable perinatal outcomes, in which the placenta was removed. The cases were seen at a Level IV institution in the city of Cali, Colombia. Review of the literature registered in the Medline data base via Pubmed using the search terms "abdominal pregnancy", "splenic pregnancy", "hepatic pregnancy", "omental pregnancy" and "peritoneal pregnancy". The search was limited to articles published in English and Spanish during the past 12 years. Results: Overall, 228 references were retrieved, of which 42 articles reporting on a total of 74 patients with ectopic abdominal pregnancy met the inclusion criteria. Regarding the management of the placenta, it was removed in 42 cases (58%). There were 4 cases of maternal mortality (4,1%) all of them due to postpartum bleeding. Complications occurred in 60 patients (81%), bleeding being the most frequent in 38 of them (51%). As for perinatal outcome, perinatal mortality was 43.8%. Conclusion: Placental management is the the key determinant factor of the frequency of maternal complications. Prospective studies to assess the safest and most effective management of this condition are required.
