RESUMEN

Fundamento: el hematoma duodenal es una entidad poco frecuente y para su diagnóstico es preciso considerar la existencia de factores de riesgo, las manifestaciones clínicas y el modo de diagnóstico, entre estos, el imagenológico. Objetivo: mostrar distintas formas clínicas e imagenológicas de presentación del hematoma duodenal según tipo de estudio y tiempo de evolución. Presentación de casos: se presentaron tres casos de hematoma duodenal diagnosticados en diferentes periodos evolutivos. El antecedente traumático no fue recogido al inicio en dos de ellos pero las investigaciones imagenológicas orientaron su diagnóstico. El vómito y el dolor abdominal estuvieron presentes en los tres, la anemia, el tinte sub-ictérico y la toma del estado general en el caso de diagnóstico tardío de tres meses de evolución. El cuadro oclusivo intestinal alto surge secundario a una endoscopia con escleroterapia por úlcera sangrante en el tercer caso de forma aguda. En la ecografía, la radiografía contrastada del tubo digestivo y la tomografía axial computarizada se apreciaron variaciones del patrón en dependencia al tiempo de evolución. La ecografía como primer estudio detectó la colección en todos ellos y fue útil en el seguimiento, el estudio radiológico contrastado orientó el diagnóstico con predominio de patrón anfractuoso en el caso tardío, y la tomografía ofreció la mayor información. Conclusiones: para el diagnóstico del hematoma duodenal es necesario tenerlo presente e indagar sobre factores de riesgo, acudir a los medios diagnósticos disponibles y considerar que sus manifestaciones pueden variar según el tiempo de evolución. Se considera la tomografía como examen de elección (AU)

Background: the duodenal hematoma is an infrequent entity, usually of late diagnosis, which should be made according to risk factors, the clinical manifestations and imaging studies. Objective: to show different clinical and imaging forms of presentation of duodenal hematoma according to type of imaging study and time of progress.Cases reports: three cases of duodenal hematoma diagnosed in different follow up periods are presented. The history of the trauma was not recorded at the beginning in two cases neither considered as a predisposing factor, but the diagnostic research suspected the diagnosis. Vomiting and abdominal pain was seen in all three cases. Anemia, sub-jaundice dye and malaise were present at three months of follow up. Upper acute intestinal occlusive condition was secondary to endoscopic sclera-therapy due to digestive bleeding in the third case. Ultrasound, contrast radiography of the digestive tube and computerized axial tomography showed variations of the pattern depending on the modifications of the hematoma over time. Ultrasound as the first study detected the collection in all cases and was useful in the follow-up. Contrast radiological study was oriented towards the diagnosis and show predominance of regular patterns in case of late diagnosis. The Tomography achieved a greater diagnostic definition. Conclusions: for the diagnosis of duodenal hematoma, it is necessary to take into account and think about risk factors, and the proper management of imaging studies in relation to time of progress. Tomography is the examination of choice (AU)

RESUMEN

Primary aortoenteric fistula is the spontaneous communication between the lumen of the aorta and a portion of the digestive tract. The most common cause is the erosion of an abdominal aortic aneurysm into the 3rd or 4th portion of the duodenum. It manifests clinically as gastrointestinal bleeding, with or without abdominal pain and a pulsatile abdominal mass on physical exam. Gastrointestinal bleeding is initially recurrent and self-limiting and progresses to fatal exsanguinating hemorrhage. Endoscopic examination diagnoses only 25% of aortoenteric fistulas because these are usually located in the distal duodenum. Contrast computed tomography of the abdomen and pelvis is diagnostic in only 60% of cases. We report three cases with this condition. A 67-year-old male presenting with an upper gastrointestinal bleeding. He was operated and a communication between an aortic aneurysm and the duodenum was found and surgically repaired. The patient is well. A 67-year-old male with an abdominal aortic aneurysm presenting with abdominal pain. He was operated and anticoagulated. In the postoperative period he had a massive gastrointestinal bleeding and a new CAT scan revealed an aorto enteric fistula that was surgically repaired. The patient is well. An 82-year-old male with an abdominal aortic aneurysm presenting with hematochezia. A CAT scan revealed a communication between the aneurysm and the third portion of the duodenum, that was surgically repaired. The patient died in the eighth postoperative day.

RESUMEN

Pseudomelanosis duodeni is a very rare appearance of the duodenal mucosa, characterized by the presence of a dark pigment (iron oxide) seen in the surface of the villi, evident by endoscopy. It can be associated with pathologies such as arterial hypertension, chronic heart failure, chronic kidney failure, gastrointestinal bleeding, and consumption of different drugs. We describe the case of a 68-year-old male patient, with chronic renal insufficiency, hemodialysis and intravenous iron treatment.

La Pseudomelanosis duodeni es una entidad muy poco frecuente de la mucosa duodenal que se caracteriza por la presencia de un pigmento oscuro de las vellosidades (oxido de hierro) que es evidente mediante endoscopía y puede estar asociado a patologías como hipertensión arterial, insuficiencia cardíaca crónica, insuficiencia renal crónica, hemorragia gastrointestinal y consumo de diferentes fármacos. Describimos el caso de un paciente masculino de 68 años, con antecedentes de insuficiencia renal crónica, en hemodiálisis y uso de hierro intravenoso.

RESUMEN

El síndrome de la arteria mesentérica superior es una enfermedad poco frecuente en pediatría. Se produce por la compresión de la tercera porción duodenal a su paso entre la arteria mesentérica superior y la aorta abdominal (compás aortomesentérico). La mayoría de los pacientes presentan factores predisponentes:pérdida de peso aguda o compresiones extraabdominales.Se presenta el caso de una niña de 12 años de edad a quien se le diagnosticó el síndrome sin presentar factores predisponentes.Comenzó de modo súbito con náuseas, vómitos incoercibles y dolor abdominal, que era posprandial y se aliviaba, llamativamente, en decúbito lateral izquierdo. Esto constituyó la sospecha clínica del síndrome, por lo que se solicitó una angio tomografía computada abdominal y se observó el estrechamiento del compás aortomesentérico. Se realizó un tratamiento médico conservador, sin respuesta clínica. Se decidió el tratamiento quirúrgico y se logró la resolución del cuadro clínico

The superior mesenteric artery syndrome is rarely seen in children. It results from an intestinal obstruction due to compression of the third portion of duodenum between the superior mesenteric artery and the abdominal aorta. In most of the cases there are predisposing factors such as rapid weight loss or extra-abdominal compression.We report a case of a superior mesenteric artery syndrome in a twelve-year-old female patient without predisposing factors. The girl began suddenly with nauseas, continuous vomiting and abdominal pain. The abdominal pain was postprandial and it decreased in left lateral decubitus position. Clinically, this characteristic suggested superior mesenteric artery syndrome. Angio-computed tomography scan confirmed the diagnosis. Given that conservative treatment ultimately failed, patient was subjected to surgery and the illness was resolved.

RESUMEN

ABSTRACT CONTEXT: Spontaneous intramural duodenal hematoma is uncommon and is usually associated with coagulopathy, anticoagulant therapy and endoscopic procedures. The aim here was to describe a case of intramural duodenal hematoma caused by chronic exacerbation of pancreatitis. CASE REPORT: A 46-year-old male with chronic alcoholic pancreatitis was admitted to hospital due to abdominal pain, melena and low hemoglobin. An intramural duodenal hematoma with active bleeding was detected and selective angioembolization was warranted. The patient evolved with a perforated duodenum and underwent laparotomy with exclusion of the pylorus and Roux-en-Y gastrojejunostomy. He was discharged nine days later. CONCLUSION: Intramural duodenal hematoma is a rare complication of pancreatitis. Selective embolization is the preferred treatment for hemorrhagic complications of pancreatitis. However, the risk of visceral ischemia and perforation should be considered.

RESUMEN

Objetivo: Caracterizar la mucosa gástrica heterotópica en duodeno en nuestro medio. Materiales y métodos: Se seleccionaron dos instituciones, los casos de mucosa gástrica heterotópica que cumplieran los criterios histológicos establecidos para el diagnóstico durante los años 2014-2015. Las láminas con el diagnóstico de mucosa gástrica heterotópica en duodeno fueron revisadas por 3 patólogos, se recolectó información clínica, endoscópica e histológica en cada caso. Resultados: Se encontraron 45 casos de mucosa gástrica heterotópica en duodeno, 91,1% se localizaron en bulbo duodenal y 73,2% se presentaron endoscópicamente como pólipos. En todos los casos se identificó células parietales como criterio para hacer el diagnóstico histopatológico, en ningún caso se identificó Helicobacter pylori ni displasia en la biopsia duodenal. Conclusiones: Nuestros datos confirman su naturaleza benigna. El diagnóstico de mucosa gástrica heterotópica, aunque infrecuente, debe tenerse en cuenta en el estudio de pólipos duodenales, siendo la identificación de células parietales en mucosa duodenal fundamental para el diagnóstico diferencial histológico especialmente con la metaplasia gástrica de duodenitis péptica

RESUMEN

BACKGROUND: Wilkie syndrome, also referred as superior mesenteric artery syndrome, is an unusual cause of a proximal small bowel obstruction. It is characterised by the compression of the duodenum in its third portion due to a narrowing of the space between the superior mesenteric artery and the aorta. Its presentation symptoms are consistent and include the obstruction of the proximal small bowel. However, the physical and laboratory findings are non-specific. Nevertheless, many imaging methods are useful for its diagnosis. The management of this condition varies between observation and surgery, depending on each particular case. CLINICAL CASE: The case is presented of a 19 year-old male who began with acute, intense abdominal pain, nausea, vomiting, and diarrhoea. On examination, he had abdominal wall rigidity and hyperesthesia. Imaging studies were requested, revealing a decreased superior mesenteric artery angle, a shortening of the aortic mesenteric distance, and a decrease in the calibre of the third duodenal portion, all findings concomitant with Wilkie syndrome. Conservative treatment was applied and the patient was discharged without complications. CONCLUSIONS: Wilkie syndrome continues to be an unknown condition to the general practitioner, and the underdiagnosis of this condition may put a patient at risk of serious complications. A high index of suspicion is required to reach a diagnosis. Early treatment should give a good outcome most of the time.

RESUMEN

A 59 year-old patient was admitted with upper gastrointestinal bleeding. The clinical exam showed mild hypotension and blood samples revealed acute anemia (hemoglobin = 7.5 g/dl). Emergency computed tomography showed an infrarenal abdominal aortic aneurysm and extravasation of the arterial contrast material toward the digestive tract. The patient was transported to the operating room for emergency laparotomy, which showed an aortoduodenal fistula. After proximal and distal aortic vascular control, the two anatomical structures were dissected with duodenorrhaphy, patch repair of the aortic tear and omentum interposition. The postoperative recovery was uneventful, with discharge after 12 days.
