Fístula aorto-duodenal primaria: caso clínico / Primary aorto-duodenal fistula: clinical case

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.

Divertículo duodenal en la tercera porción del duodeno como causa de sangrado del tubo digestivo alto y dolor crónico abdominal: informe de un caso y revisión de la literatura / Duodenal diverticulum in the third portion of duodenum as a cause of upper gastrointestinal bleeding and chronic abdominal pain: case report and literature review

BACKGROUND: Duodenal diverticulum is a little-known pathology. The duodenum represents second place in frequency for the presence of diverticula in the digestive tract after the colon. Duodenal diverticulum as a cause of hemorrhage of the upper gastrointestinal (GI) tract has been described as an infrequent complication, although it must be considered in patients with digestive hemorrhage without evident cause at the esophagogastric level. Localization of diverticula in the third or fourth portions of the duodenum is rare and the diverticula are asymptomatic in 90% of cases. Diagnosis is made by endoscopy, contrast X-rays of the upper GI tract, selective arteriography and as a transoperative finding. The objective of this study was to identify and analyze the clinical presentation of duodenal diverticulum to familiarize surgeons and gastroenterologists when there is suspicion of the diagnosis. CLINICAL CASE: We report the case of an 85-year-old female presenting with massive upper GI tract hemorrhage and chronic abdominal pain due to a duodenal diverticulum located in the third portion of the duodenum. Diagnosis was made with upper GI barium series because visualization of the diverticulum was not possible by endoscopy. Other therapeutic options are described in the literature. A successful simple diverticulectomy, manually opened with a two-plane transversal incision, was performed on the patient. After >12 months of follow-up, the patient is completely asymptomatic. DISCUSSION: Clinical diagnosis presents difficulty because a classic presentation does not exist. Symptoms are generally vague, <10% of the duodenal diverticulum are frankly symptomatic, and <1 to 2% will require surgical resolution. CONCLUSIONS: Hemorrhage of the upper GI tract and chronic abdominal pain secondary to duodenal diverticulum present with recurrence and may be associated with the presence of duodenal diverticulum when other sources of bleeding are not found.
