ABSTRACT

Resumo A fístula aortoentérica é uma grave condição clínica, e seu manejo permanece sendo um grande desafio técnico aos cirurgiões. A abordagem por cirurgia convencional nesses casos está relacionada a altos índices de morbimortalidade. A cirurgia endovascular apresenta-se como uma ótima alternativa nesses casos; contudo, por não se tratar de aorta nativa, a anatomia pode não ser compatível com os dispositivos endovasculares comercialmente disponíveis, fazendo-se necessário, em casos de urgência, a utilização de dispositivos modificados pelo cirurgião. O caso relatado reporta uma fístula aortoentérica secundária, tratada em situação de urgência por técnica endovascular com dispositivo modificado.


Abstract Aortoenteric fistula is a severe clinical condition and its management remains a major technical challenge for surgeons. In these cases, the conventional surgical approach is associated with high rates of morbidity and mortality. Endovascular surgery is an excellent option in these cases, but considering that the aorta has been treated previously, anatomy may not be compatible with commercially available endovascular devices and so physician-modified endografts may be needed in urgent cases. The case reported involves a secondary aortoenteric fistula, treated on an emergency basis with endovascular techniques, using a physician-modified endograft.

ABSTRACT

RESUMEN Introducción: Las fístulas aorto-entéricas son una causa infrecuente de hemorragia digestiva. El pronóstico, generalmente ominoso, depende de una alta sospecha clínica y diagnóstico oportuno. Objetivo: Presentar el caso de una hemorragia digestiva por una fístula Aortoentérica diagnosticada y tratada. Presentación del caso: Se reporta el caso de un hombre de 72 años intervenido con el diagnóstico hemorragia digestiva masiva en el preoperatorio; sin embargo, el diagnóstico de la fístula se hizo en el intraoperatorio, sin observar dilatación aneurismática, pero si una aorta ateromatosa y un proceso inflamatorio hacia la fístula. Se realizó reparación quirúrgica urgente con reparación cara anterior aorta infrarrenal cercana a la bifurcación y resección del íleo terminal con ileoascendentostomía termino-lateral. Discusión: Las fístulas aorto-entéricas es una causa potencialmente fatal de hemorragia digestiva. El diagnóstico continúa siendo un desafío debido a su presentación inespecífica y siempre debiese ser considerado frente a una hemorragia digestiva sin causa aparente. Existen varias opciones para el enfrentamiento quirúrgico que deben ser analizadas caso a caso, sin retrasar la reparación. Conclusiones: La fístula aorto-entérica primaria es una causa poco frecuente de hemorragia digestiva, que todo médico y cirujano debe tener en cuenta frente a un paciente con sangrado digestivo de causa no precisada(AU)


ABSTRACT Introduction: Aortoenteric fistulas are a rare cause of gastrointestinal bleeding. The generally ominous prognosis depends on high clinical suspicion and timely diagnosis. Objective: To present a case of gastrointestinal hemorrhage for aortoenteric fistula diagnosed and treated. Case presentation: The case is reported of a 72-year-old man who received surgery after the diagnosis of massive gastrointestinal bleeding during the preoperative period. However, the diagnosis of the fistula was made intraoperatively, without observing aneurysmal dilation, but an atheromatous aorta and an inflammatory process leading to the fistula instead. Urgent surgical repair was performed with repair of anterior infrarenal aorta near the bifurcation and resection of the terminal ileum with end-to-side ascending ileostomy. Discussion: Aortoenteric fistulas are a potentially fatal cause for gastrointestinal bleeding. Diagnosis continues to be a challenge due to its nonspecific presentation and should always be considered for any case of unexplained gastrointestinal bleeding. There are several options for surgical management that must be analyzed case by case, without delaying repair. Conclusions: Primary aortoenteric fistula is a rare cause for gastrointestinal bleeding, which every doctor and surgeon must take into account when dealing with a patient with digestive bleeding of an unspecified cause(AU)

ABSTRACT

Resumen Introducción Las fístulas aorto-entéricas (FAE) son una causa infrecuente de hemorragia digestiva. El pronóstico, generalmente ominoso, depende de una alta sospecha clínica y diagnóstico oportuno. Caso clínico Reportamos el caso de una mujer de 66 años intervenida por un aneurisma sacular aórtico abdominal (AAA) yuxtarrenal, con rotura contenida, fistulizado al duodeno. Presentó una hemorragia digestiva en el preoperatorio; sin embargo, el diagnóstico de la fístula se hizo en el intraoperatorio. La paciente fue sometida a reparación quirúrgica urgente con instalación de una prótesis aórtica bifemoral y resección duodenal. En el postoperatorio inmediato presentó una trombosis parcial de las ramas de la prótesis aórtica e isquemia de extremidades, siendo reintervenida exitosamente. Discusión La FAE es una causa potencialmente fatal de hemorragia digestiva. El diagnóstico continúa siendo un desafío debido a su presentación inespecífica y siempre debiese ser considerado frente a una hemorragia digestiva sin causa aparente. Existen varias opciones para el enfrentamiento quirúrgico que deben ser analizadas caso a caso, sin retrasar la reparación de la fístula. Es preferible la resección duodenal ante la simple duodenorrafia.


Introduction Aorto-enteric fistulae (AEF) are a rare cause of gastrointestinal bleeding. The prognosis tends to be ominous, depending greatly in a high level of clinical suspicion and prompt diagnosis. Clinical case We report a case of a 66-year-old female with a saccular juxta-renal abdominal aortic aneurysm (AAA), with a contained rupture. The patient was urgently submitted to surgical repair using an bifemoral aortic prosthesis. A duodenal partial resection was performed. During the immediate postoperative time she presented partial thrombosis of prosthesis and ischemia of lower extremities so she was reoperated successfully. Discussion AEF is a potentially fatal cause of gastrointestinal bleeding. Diagnosis is still troublesome due to its vague presentation and it should always be considered when facing gastrointestinal haemorrhage with no apparent cause. There are several surgical approaches that should be pondered case to case without delaying the repair of the defect.

ABSTRACT

A correção de aneurisma de aorta abdominal tem sido sua principal indicação o implante de endoprótese (EDV) quando a anatomia for favorável. Apresenta infecção em pós-operatório (PO) baixa, mais relacionados a procedimentos complementares. A ocorrência de fístula aorto-entérica é mais complexa, mas frequentemente associada a infecção pós-EDV. Representa um desafio operatório em um paciente muitas vezes debilitado. A antibioticoterapia é utilizada por longo tempo e de largo espectro. Neste trabalho, apresentaremos um caso de fístula aorto-entérica pós implante de EDV e a conduta que foi realizada para o seu tratamento.


The principal indication for repair of abdominal aortic aneurysm is the endovascular approach when the aortic anatomy is favorable. Graft infection has lower incidence, more related to re-intervations after the endovascular approach. It represents an operational challenge in a often debilitated patient. The antibiotic therapy is long and with a broad spectrum. In this work we will present a case with secondary aortic fistulae after endovascular repair and the decisions for the treatment.

ABSTRACT

La fístula aortoentérica (FAE) es la solución de continuidad entre la arteria aorta y una porción del sistema digestivo; su incidencia va del 0.04 al 0.07% y su mortalidad alcanza hasta 79%, lo que la convierte en un verdadero reto a la hora de establecer su manejo por la efectividad con la cual se debe efectuar su manejo. Existen diversas manifestaciones de la enfermedad que pueden distraer su diagnóstico, sin embargo es común el dolor abdominal y el sangrado digestivo acompañado o no de signos de inestabilidad hemodinámica. Actualmente, no existe un consenso para el manejo de las FAE; sin embargo, los pilares fundamentales son: control de la infección, reparación vascular y reconstrucción entérica; para esto es indispensable un equipo multidisciplinario de gran experiencia. Se presenta el caso de una paciente de 76 años con varias comorbilidades, portadora de bypass aorto-bi-femoral por enfermedad aterosclerótica de la aorta. Acudió por dolor abdominal, sangrado digestivo alto e inestabilidad hemodinámica. Luego de la valoración inicial fue diagnosticada de FAE y sepsis. Tomando en cuenta las recomendaciones mundiales, se realizó un procedimiento en 2 tiempos que incluían: a) reparo vascular: bypass extra-anatómico, exéresis de prótesis y cierre del muñón aórtico y, b) reparo entérico (por la magnitud anatómica de la lesión intestinal y luego de haber descartado la factibilidad de una rafia o derivación intestinal): como último recurso un procedimiento de Whipple


Aortoenteric fistulas are defined as a communication between the aorta and a portion of the digestive system. This pathology has a 0.04-0.07% incidence with a mortality rate of up to 79% making it's management a true challenge. Clinical manifestations vary thus common symptoms include abdominal pain and digestive bleeding and may or may not include signs of hemodynamic instability. Until now there is no consensus regarding the management of FAE hence the pillars of treatment include: infection control, vascular reparation and enteric reconstruction. A multidisciplinary team is imperative. We are presenting the case of a 76-year-old female with various comorbidities and a history of an aortic bifemoral bypass reconstruction due to aortic sclerosis disease; that presented with abdominal pain, upper digestive bleeding and hemodynamic instability. She was diagnosed with a FAE and sepsis. Taking into consideration international recommendations she was treated with a single procedure in two times. For the vascular correction: an extra-anatomical bypass; removal of previous prosthetic aortic implant and closure of the aortic stump. Due to the magnitude of the intestinal damage simple closure and intestinal derivation were discarded as options for enteric repair and a Whipple procedure was used as a last resource.

ABSTRACT

La hemorragia digestiva alta es un síndrome frecuente que aparece como complicación de enfermedades, no sólo digestivas, sino también sistémicas. Aunque 85-90% de los episodios hemorrágicos se interrumpen de forma espontánea o gracias a medidas conservadoras, entre 10 y 25% de los pacientes requieren una intervención quirúrgica urgente. Actualmente, la mortalidad ha descendido hasta 4 ó 9% en pacientes menores de 60 años y, en los mayores de 60 años oscila entre 14 y 30%, teniendo gran valor la gastroduodenoscopía fibro-óptica como exploración de rutina. No obstante, la creciente proporción de pacientes mayores de 60 años con este síndrome ha hecho que estas cifras permanezcan estacionarias. A continuación exponemos la Historia clínica de un paciente de la tercera edad que presentó una hemorragia digestiva alta, resultado de una fístula aorto-entérica secundaria, quien falleciera antes de ser intervenido de urgencia. Se exponen actualizados los aspectos más importantes de dicha entidad nosológica y su tratamiento.


Upper digestive hemorrhage is a common sindrome that appears not only secondary to digestive diseases but also a systemic too. Although 85 to 90% of those episode stop spontaneously or with medical treatment, mortality rate, nowdays has been decreased to 4 or 9% in patients below sixty years old and in patients over 60 years old, mortality rate, are between 14 to 30%. Fiberoptic endoscopy has become the optimal diagnostic procedure. Nevertheless the increase of life rate had become a cause that these mortality rate state stationary. The objective of this report is to presents the history of a geriatric patient with an upper digestive bleeding due to a secondary aortoenteric fistula, who died before an attempt to surgical stop the bleeding and to review this subject.

ABSTRACT

The present study aimed to experimentally evaluate the protection role of glycerin preserved bovine peritoneum (BP) against intestinal adhesions to a vascular graft. Experiments were performed on 24 adult rabbits, randomly dived into two groups. All animals were submitted to a vascular graft over the infra-renal aorta and vena cava. Group 1(12 animals ) was submitted to a BP patch on the retroperitoneal opening, between the vascular prosthetic graft and the intestinal loops. Group II (12 animals ) had the retroperitoneal opening sutured. After 7, 14, 28 and 60 days, 3 animals of each group were randomly killed and the retro peritoneum, with or without the BPpatch, was removed for histological analysis. The histological analysis showed that the BP stimulated a moderate to intense inflammatory reaction at the beginning of the experiments and on the 60-day evaluation, the inflammatory reaction was mild, limited to the BP border with its histological structure preserved. In conclusion, the BP is a safe and cheap interposition material to be used between vascular grafts and intestinal loops, presenting a protection role against adhesions between them.


El objetivo de este estudio fue evaluar experimentalmente el rol protector del peritoneo bovino (PB) preservado en la glicerina en contra de las adherencias intestinales de un injerto vascular. Los experimentos se realizaron en 24 conejos adultos, randomizados aleatoriamente en dos grupos. Todos los animales fueron sometidos a un injerto vascular sobre la aorta infra-renal y la vena cava. Grupo I (12 animales), fue sometido a un parche PB en una apertura retroperitoneal suturada, entre el injerto vascular y el intestino. Grupo II (12 animales) con la apertura retroperitoneal suturada. Después de 7, 14, 28 y 60 días, 3 animales de cada grupo fueron sacrificados al azar y el retro peritoneo, con o sin el parche de PB, se retiró para el análisis histológico. El análisis histológico mostró que la PB estimuló una moderada a intensa reacción inflamatoria al inicio de los experimentos y en la evaluación de 60 días, la reacción inflamatoria fue leve, limitada a los bordes de la PB con su estructura histológica preservada. En conclusión, la PB es una forma segura y barata de material de interposición para ser utilizada entre injertos vasculares e intestinales, presentando un rol de protección contra adherencias entre ellos.
