Pseudomelanosis duodeni: a propósito de un caso - revisión de literatura / Pseudomelanosis duodeni: a case report - literature review

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.

Síndrome de la arteria mesentérica superior en una adolescente de 12 años. Caso clínico / Superior mesenteric artery syndrome in a 12-year-old adolescent. Clinical case

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.

Intramural duodenal hematoma secondary to pancreatitis: case report and review of the literature

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.

Mucosa gástrica heterotópica en duodeno: características clínicas endoscópicas e histológicas / Heterotopic gastric mucosa in duodenum: endoscopic and histological features

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

Objective: The aim of this study was characterized sin duodenum the heterotopic gastric mucosa. Materials and methods: The slides with the diagnosis of heterotopic gastric mucosa during 2014-2015, were reviewed, and clinical, histological and endoscopic data was to collected for every case. Results: 45 cases of heterotopic gastric mucosa in duodenum were found, 91.1% were located in duodenum bulb and 73.2%, presenting as polyps in 73.2% of cases. In all cases, parietal cell was identified as main criteria for the diagnosis. Neither Helicobacter pylori nor dysplasia were identified. Conclusions: Our data confirm its non neoplastic nature. Heterotopic gastric mucosa should be taken into account in diagnosis of duodenal polyps. Parietal cells identification in duodenal mucosa is essential in differential diagnosis with peptic duodenitis

Primary aortoduodenal fistula: first you should suspect it

ABSTRACT 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.

A Case of an Intraluminal Duodenal Diverticulum Managed with Endoscopic Incision and Ligation using Needle-knife and Detachable Snare / 대한소화기학회지

An intraluminal duodenal diverticulum (IDD) is a rare congenital anomaly consisted of a sac-like mucosal projection within the second portion of the duodenum. Even though most of cases are asymptomatic, patients may develop recurrent abdominal pain, pancreatitis, and gastrointestinal bleeding. We report a case of symptomatic IDD which presented as acute pancreatitis and obscure gastrointestinal bleeding. Diagnosis was made by typical findings of upper GI series and coronal reformatted CT images. Although surgical resection is the treatment of choice, endoscopic incision and ligation with detachable snare was performed which led to a good result.

Duodenal tuberculosis: radiological features on barium studies and their clinical correlation in 28 cases.

BACKGROUND: A retrospective analysis of 28 cases of duodenal tuberculosis (TB) was done to evaluate radiological findings and their value in the diagnosis of the disease. SUBJECTS AND METHODS: Upper gastrointestinal and small bowel series of 28 patients with duodenal tuberculosis were analysed for radiological findings. The diagnosis of duodenal TB was confirmed by surgery and biopsy in 18, on the basis of radiological findings and response to treatment in 9, and on the basis of findings on upper gastrointestinal scopy and biopsy in 1 patient. RESULTS: The study included 28 patients (14 males, 14 females). The mean age was 32.1 (range 5-65). Twenty-three (82.2%) patients presented with obstructive symptoms while five manifested with dyspeptic symptoms. Of the latter, 4 had ulcerations in the third and fourth parts of the duodenum. In the remaining patient, the mucosa of the duodenum could not be clearly visualised. Two patients had extrinsic impression at the D2-D3 and D3-D4 segments. In 23 patients with obstructive symptoms, 18 demonstrated luminal narrowing of varying degrees and 5 had a sharp band-like cut-off at the third part of the duodenum. Of the 18 patients with luminal narrowing, 13 had extrinsic compression, 12 had proximal dilatation and 14 had ulcerations mainly in the second and third parts of the duodenum. Biliary involvement was seen in 3 patients without any signs or symptoms directly referable to the biliary involvement. CONCLUSION: Though duodenal TB lacks specific radiological features, barium studies help to localise and define the area of narrowing and ulcerations and help to confirm the presence of lymph nodes causing compression of the duodenum.

Isolated duodenal metastasis from breast carcinoma.

Small bowel neoplasms comprise 0.1% of all malignancies. Of these one-third are duodenal, mainly primary. Isolated duodenal secondaries arising on account of haematogenous spread is rare. Our case of duodenal obstruction due to an isolated duodenal metastasis as a result of haematogenous spread from breast carcinoma is unique in the literature.
