RESUMO

INTRODUCTION AND HYPOTHESIS: The aim of the study is to facilitate the suture on the sacral promontory for laparoscopic sacrocolpopexy. We hypothesised that a new method of sacral anchorage using a biosynthetic material, the polyether ether ketone (PEEK) harpoon, might be adequate because of its tensile strength, might reduce complications owing to its well-known biocompatibility, and might shorten the duration of surgery. METHODS: We verified the feasibility of insertion and quantified the stress resistance of the harpoons placed in the promontory in nine fresh cadavers, using four stress tests in each case. Mean values were analysed and compared using the Wilcoxon and Fisher's exact tests. RESULTS: The harpoon resists for at least 30 s against a pulling force of 1 N, 5 N and 10 N. Maximum tensile strength is 21 N for the harpoon and 32 N for the suture. Harpoons broke in 6 % and threads in 22 % of cases. Harpoons detached owing to ligament rupture in 64 % of the cases. Regarding failures of the whole complex, the failure involves the harpoon in 92 % of cases and the thread in 56 %. The four possible placements of the harpoon in the promontory were equally safe in terms of resistance to traction. CONCLUSIONS: The PEEK harpoon can be easily anchored in the promontory. Thread is more resistant to traction than the harpoon, but the latter makes the surgical technique easier. Any of the four locations tested is feasible for anchoring the device.

RESUMO

Objetivo. Determinar la efectividad de la ecografía del primer trimestre en el diagnóstico de mola hidatiforme completa o parcial. Pacientes y métodos. Se evaluaron todos los casos de sospecha ecográfica de mola hidatiforme y/o diagnóstico histológico confirmado de nuestro centro desde enero 1998 hasta diciembre 2010. Se calcula la sensibilidad y el valor predictivo positivo de la ecografía en la detección de la gestación molar. Resultados. El grupo de estudio incluyó 59 pacientes. En 49 se sospechó ecográficamente mola hidatiforme, 39 de los cuales fueron confirmados histológicamente (27 parciales y 12 completas). En los 10 casos restantes el diagnóstico histológico fue de aborto. Durante el mismo período, la histopatología demostró una gestación molar en otras 10 pacientes (9 parciales y 1 completa) previamente diagnosticadas de aborto por ecografía. Por tanto, el estudio incluyó un total de 49 casos de diagnóstico final de mola hidatiforme (36 parciales y 13 completas). La sensibilidad y valor predictivo positivo de la ecografía en el diagnóstico de mola hidatiforme fue de 79.6% (39/49) y 79.6% (39/49) respectivamente, y 10/49 (20.4%) gestaciones molares no fueron correctamente identificadas. Aunque la tasa de detección ecográfica para la mola hidatiforme completa (12/13, 92.3%) fue discretamente superior a la de mola parcial (27/36, 75%), la diferencia no fue significativa (p=0.18). Conclusión. La efectividad de la ecografía del primer trimestre para diagnosticar mola hidatiforme es elevada. No hallamos diferencias significativas entre el diagnóstico de mola hidatiforme parcial y completa. Ante la existencia de un número no despreciable de molas no detectables por ecografía, recomendamos realizar estudio histológico en todos los casos de aborto (AU)


Objective. To assess the accuracy of first trimester ultrasound to diagnose complete or partial hydatidiform moles. Patients and methods. All cases of sonographically suspected and/or histologically proven complete or partial hydatidiform mole diagnosed in our center from January 1998 to December 2010 were analyzed. The sensitivity and positive predictive value of ultrasound in the detection of molar pregnancies were calculated. Results. The study group included 59 patients. Of these, 49 were suspected of having hydatidiform mole by ultrasound, 39 of which were histologically confirmed (27 partial and 12 complete). In the remaining 10 cases, the histological diagnosis was pregnancy loss. During the same period, histopathology demonstrated molar pregnancy in a further 10 patients (nine partial and one complete) previously diagnosed as pregnancy loss by ultrasound. Therefore, the study included a total of 49 cases with a final diagnosis of hydatidiform mole (36 partial, 13 complete). The sensitivity and positive predictive value of ultrasound in first-trimester hydatidiform mole was 79.6% (39/49) and 79.6% (39/49) respectively. Of the 49 molar pregnancies, 10 (20.4%) were not identified correctly. The detection rate for complete mole (12/13, 92.3%) was slightly better than that for partial mole (27/36, 75%) but this difference was not significant (p=0.18). Conclusion. The accuracy of first-trimester ultrasound in the diagnosis of hydatidiform mole is high. No significant differences were found between the diagnosis of partial and complete hydatidiform mole. In view of the significant number of molar pregnancies not diagnosed by ultrasound, we recommend histopathological evaluation of all cases of pregnancy loss (AU)

RESUMO

Vasa previa (VP) es una complicación obstétrica infrecuente en la que los vasos sanguíneos aberrantes procedentes de la placenta o del cordón umbilical cruzan la entrada del canal del parto por delante de la presentación. Si no se diagnostica antes del inicio del parto o de la amniorrexis, la morbimortalidad fetal es elevada. Se presenta el caso de una paciente diagnosticada mediante ecografía de placenta bilobulada de inserción baja, con clínica de metrorragia de tercer trimestre, en la que la ecografía transvaginal con Doppler color y pulsado demostró la existencia de VP. Se discute la etiología y el manejo clínico de esta entidad infrecuente (AU)


Vasa previa is an uncommon obstetric complication in which aberrant vessels coming from the placenta or the umbilical cord cross over the internal cervical os, thus appearing immediately before the foetal presentation. If it is not diagnosed before the onset of labour or rupture of membranes, the perinatal outcome is general very poor. We report a case of vasa previa which was prenatally diagnosed by ultrasound in a woman presenting with antepartum bleeding and a low-lying bilobular placenta in the third trimester. The a etiology and clinical management of this condition are discussed (AU)

RESUMO

Retrorectal cystic hamartomas (tailgut cysts) are rare congenital lesions thought to arise from remnants of the embryonic postanal gut. They predominantly occur as asymptomatic retrorectal multicystic masses in women. The treatment of choice is by complete surgical excision. The most important complications of these cysts are infection with a secondary fistula and malignant degeneration. The differential diagnosis includes a wide variety of conditions that occur in the retrorectal space. In this article, 3 cases showing different surgical technical aspects of treatment are presented. In addition, the aetiopathogenic features and histopathological appearance, clinical presentation and complications, imaging features and differential diagnosis of tailgut cysts are described.

RESUMO

Los hamartomas quísticos retrorrectales (tailgut cysts) son tumores congénitos poco frecuentes derivados de remanentes embrionarios postanales del intestino. La mayoría de los hamartomas quísticos son multiquísticos y aparecen como masas asintomáticas en mujeres de mediana edad. El tratamiento de elección es la extirpación completa. Las complicaciones más frecuentes son la infección y el desarrollo de fístulas cutáneas y la degeneración maligna. El diagnóstico diferencial incluye una extensa variedad de patologías que pueden existir en el espacio retrorrectal. En este artículo presentamos 3 pacientes con hamartomas quísticos y realizamos una revisión de su etiopatogenia, las manifestaciones clínicas, las técnicas de diagnóstico, sus complicaciones y los diagnósticos diferenciales. Asimismo, se discuten las diferentes técnicas quirúrgicas posibles para su abordaje quirúrgico (AU)

RESUMO

Objetivo: Describir las distancias entre las principales estructuras óseas, vasculares, neurológicas y viscerales que son relevantes para guiar el paso de las agujas insertoras en las técnicas quirúrgicas a través del foramen obturador. Material y métodos: Se diseccionaron 6 hemipelvis femeninas de cadáver embalsamado, procedentes de donantes de cuerpo voluntarias del Departament de Ciències Morfològiques de la Universitat Autònoma de Barcelona (UAB). En la disección se hizo especial hincapié en la delimitación del agujero obturador y la localización de estructuras osteomusculoaponeuróticas y neurovasculares adyacentes. Resultados: Se midieron distintas distancias. Son especialmente relevantes las distancias en relación con la rama isquiopubiana, la espina ciática y el arco tendinoso del músculo elevador del ano, ya que constituyen las principales referencias para la cirugía. Conclusiones: Un buen conocimiento de la anatomía trae luz al paso a ciegas de los tunelizadores que utilizan el foramen obturador para acceder a la pelvis. Ello debe permitir una cirugía más segura y una mejor comprensión de los riesgos potenciales, cómo evitarlos y cómo tratar las complicaciones perioperatorias


Objective: To describe distances between the major bony, vascular, neurologic and visceral structures of importance when guiding trocar needles through the obturator foramen. Material and methods: Six embalmed female hemipelvises from voluntary donors were dissected at the Department of Anatomy of the Universitat Autònoma de Barcelona (UAB) School of Medicine. Special attention was paid to the obturator foramen and its neighboring bony, aponeurotic and muscular structures, and neurovascular bundles. Results: Several distances were collected. Distances in relation to the ischiopubic ramus, the ischial spine and the arcus tendineus of levator ani seemed to be particularly important, as they are the main landmarks for surgery. Conclusion: A good knowledge of anatomy illuminates the passage of trocar needles inserted through the obturator foramen as a route to enter the pelvic space. This knowledge improves safety, understanding of potential risks and how to avoid them, as well as the management of perioperative complications

RESUMO

El manejo tradicional del embarazo ectópico intersticial implica laparotomía y resección cornual. Los recientes avances en ultrasonografía y el desarrollo de técnicas sensibles de determinación de beta-hCG han conducido a un diagnóstico cada vez más temprano de estos casos permitiendo el empleo de opciones terapéuticas conservadoras, como el metotrexato sistémico, que se presenta como una opción segura y eficaz. Presentamos un caso de embarazo ectópico intersticial resuelto con éxito con metotrexato


Traditional management of interstitial pregnancy involves laparotomy with cornual resection. Recent advances in transvaginal ultrasonography and sensitive beta-hCG assays have led to earlier diagnosis of these cases. We report a case of interstitial pregnancy successfully treated with parenteral methotrexate. Prompt recognition of interstitial pregnancy allows conservative approachment and systemic methotrexate presents as an effective and safe option
