Utilidad de la radiografía de abdomen en el diagnóstico de la intoxicación medicamentosa: reporte de un caso pediátrico / Use of abdominal X-ray in drug intoxication: a pediatric case report

Las intoxicaciones medicamentosas son un motivo de consulta frecuente en pediatría, además de una de las principales causas externas de mortalidad en adolescentes. El diagnóstico y tratamiento tempranos son fundamentales para el manejo adecuado de estos casos. Se presenta una niña de 13 años que, luego de ingerir un fármaco desconocido, muestra decaimiento y manifestaciones clínicas gastrointestinales. Por sospecha de intoxicación con hierro y la imposibilidad de determinar los niveles de sideremia de manera urgente, se realiza radiografía de abdomen, que confirma el diagnóstico y permite el tratamiento adecuado de la paciente. En este caso, se destaca la utilidad de la radiología para el diagnóstico en la sospecha de intoxicación con hierro, gracias a la radiopacidad de sus sales

Drug intoxication is a common reason for pediatric emergency department (ED) visits and one of the leading causes of death among teenagers. Early diagnosis and treatment are essential for a proper management of these patients. We present a 13-year-old girl attended at the ED showing excessive sleepiness and gastrointestinal symptoms after taking an unknown drug. Due to suspected iron overdose and the impossibility of measuring urgent iron levels, an abdominal X-ray was performed, which confirmed the diagnosis. We highlight the utility of radiology in the diagnosis of iron poisoning, which is possible due to its radiopacity.

Divertículo colónico gigante: Dos nuevos casos en la literatura / Giant Colonic Diverticulum: Two New Cases in Literature / Divertículo gigante de colom: Dois novos casos na literatura

Introducción: El divertículo colónico gigante es una presentación rara de la enfermedad diverticular del colon descrita por primera vez en la literatura francesa en 1946; se define cuando su diámetro es mayor a 4cm. Objetivo: Adicionar a la literatura dos casos diagnosticados en la Fundación Oftalmológica de Santander, Colombia debido al bajo número de casos reportados en la actualidad; además, mencionar los principales datos encontrados en la literatura en cuanto a la epidemiología, la presentación clínica, los diagnósticos diferenciales, las herramientas diagnósticas más importantes a tener en cuenta y la diferencia de los esquemas de tratamiento. Presentación de los casos: Se presentan dos casos de pacientes con clínica de dolor abdominal para los cuales se solicitaron estudios imagenológicos que permitieron realizar un adecuado diagnóstico de divertículo colónico gigante; el primero fue manejado de manera conservadora con antibiótico-terapia y el segundo de forma quirúrgica con resección de colon transverso con anastomosis primaria. Conclusiones: El divertículo colónico gigante es una entidad poco frecuente y por tanto escasamente descrita en la literatura asociada en su mayoría con la diverticulosis. Se presenta con una clínica muy diversa, sugestiva de múltiples patologías abdominales que deben ser descartadas para poder realizar un adecuado diagnóstico por medio de técnicas de imagen como la radiografía, el colon por enema y la tomografía axial computarizada que representan las principales herramientas diagnósticas de esta entidad. El tratamiento de elección es la intervención quirúrgica, sin embargo, en contextos determinados como pacientes ancianos, asintomáticos y con alto riesgo quirúrgico puede manejarse de manera conservadora. Su importancia a pesar de la baja prevalencia radica en la necesidad del diagnóstico oportuno para evitar una alta tasa de complicaciones.

Introduction: The giant colonic diverticulum is a rare presentation of the diverticular disease of the colon described for the first time in French literature in 1946 and it is defined when its diameter is greater than 4cm. Objective: To add to the literature two more cases diagnosed in the Ophthalmological Foundation of Santander, Colombia due to the low number of cases reported today; in addition, to mention the main data found in the literature in terms of epidemiology, clinical presentation, differential diagnoses, the most important diagnostic tools to consider and the difference of treatment schemes for it. Presentation of the cases: Two cases of patients with abdominal pain clinic for whom imaging studies were requested that allowed an adequate diagnosis of giant colonic diverticulum are presented. The first one was managed conservatively with antibiotic therapy and the second one was surgically treated with a transverse colon resection with primary anastomosis. Conclusions: The giant colonic diverticulum is a rare entity and therefore poorly described in the literature associated mostly with diverticulosis. It is presented with a very diverse clinic, suggestive of multiple abdominal pathologies that must be discarded in order to perform an adequate diagnosis by means of imaging techniques such as x-rays, colon by enema and computerized axial tomography scan which represent the main diagnostic tools for this entity. The treatment of choice is surgery; however, in determined contexts such as with elderly patients who are asymptomatic and with a high surgical risk can be managed conservatively. Its importance despite its low prevalence lies in the need for timely diagnosis to avoid a high rate of complications.

Diagnostic value of different imaging methods for cholangiocarcinoma / 中华全科医师杂志

Cholangiocarcinoma is a malignant tumor that occurs in the bile duct epithelium,it is the second most common malignant tumor of the liver and bile duct after hepatocellular carcinoma.Imaging examination is an important method to detect bile duct cancer;the purpose of imaging is to determine the location of the tumor,and the extent of invasion and distant metastasis.Different imaging methods have their advantages and disadvantages,so they should be chosen based on the condition of patients,or be optimized as the combined detection.

Imaging manifestations of 92 cases of congenital intestinal malrotation / 中华围产医学杂志

Objective To investigate the imaging manifestations of congenital intestinal malrotation. Methods The clinical data of 92 infants with congenital intestinal malrotation admitted from January 1993 to December 2012 were studied retrospectively. All the 92 cases enrolled in this study were diagnosed based on imaging examinations and confirmed surgically. The imaging features of four examinations including plain abdominal radiography, upper gastrointestinal radiography, lower gastrointestinal angiography and ultrasound examination were analyzed. Results The percentage of the infants who presented with the initial clinical symptoms of vomit, blood stool and abdominal dilatation was 87.0%(80/92), 3.3%(3/92) and 1.1%(1/92), respectively, and eight cases [8.7%(8/92)] received prenatal ultrasound, which showed intestinal malrotation. Clinical examination showed no abdominal abnormalities in 68 (73.9%) cases. Seventy-seven cases underwent plain abdominal radiography, revealing intestinal obstruction in 31 cases. Thirty-six cases underwent upper gastrointestinal radiography, which revealed malrotation in 14 cases, and duodenal complete/incomplete obstruction or stenosis in 19 cases. Twenty-two cases underwent lower gastrointestinal angiography, and all of them were diagnosed as malrotation. Seventy-nine cases were examined with abdominal ultrasonography, and 58 cases were diagnosed as malrotation. Conclusions Rational selection of imaging examinations can improve the preoperative diagnosis. When congenital intestinal malrotation is suspected, abdominal ultrasound should be done as the first optional examination. At the same time, plain abdominal radiography should be selected accordingly. When intestinal malrotation with or without midgut volvulus is suggested, surgery should be performed as early as possible. When the diagnosis is not clear, upper or lower gastrointestinal radiography should be done.

Radiographic study of patients submitted to total gastrectomy using Safatle reconstruction technique / Estudo radiológico em doentes submetidos a gastrectomia total com reconstrução à Safatle

BACKGROUND: Ever since the first total gastrectomy, there has always been a great concern in increasing the survival of patients, and with the advance of techniques, in improving the quality of life of these patients. The most common reconstruction technique of the gastrointestinal transit is the Roux-en-Y. The reposition of a functional pouch in place of the resected stomach was proposed to minimize the postprandial symptoms, improve the nutritional grade and consequently, the quality of life. The Safatle reconstruction of the gastrointestinal transit technique consists of, in short, in the association of the interposition of the jejunal loop with partial transit through the duodenum, with an inverted Roux-en-Y and with the creation of a pouch which resembles the dynamics of the stomach, achieved by duodenojejunal segment which has an antiperistalsis emptying. AIM: To assess, by radiographic means, the emptying of the duodenojejunal pouch in patients submitted to total gastrectomy using the Safatle reconstruction technique. METHOD: Twelve patients submitted to total gastrectomy using the Safatle technique due to gastric cancer were studied. They were summoned to perform contrasted radiographies of the esophagus-duodenum-jejunum by the videofluoroscopic method during the months of July and August, 2005. RESULTS: All the patients presented satisfactory movement of the duodenojejunal pouch and an adequate emptying in antiperistalsis without food stasis. There has been an average 25-minute drainage time of the duodenojejunal pouch. CONCLUSION: The duodenojejunal pouch, in the patients submitted to total gastrectomy using the Safatle reconstruction, presented adequate emptying and movement.

RACIONAL: Desde a primeira gastrectomia total, houve sempre a preocupação em aumentar a sobrevida e, com o aprimoramento das técnicas, de melhorar a qualidade de vida. A técnica mais aceita para a reconstrução do trânsito intestinal após gastrectomia total é a em Y-de-Roux. A reposição de um reservatório funcional no lugar do estômago ressecado foi proposta para minimizar os sintomas pós-prandiais, melhorar o grau nutricional e, conseqüentemente, a qualidade de vida. A técnica de reconstrução do trânsito intestinal pós-gastrectomia à Safatle consiste, em síntese, numa associação da interposição de alça jejunal com trânsito parcial pelo duodeno, com o Y-de-Roux invertido, e com a criação de um reservatório que se aproxima da dinâmica do estômago, obtido à custa de um segmento duodenojejunal com esvaziamento em antiperistalse. OBJETIVO: Avaliar, por método radiológico, o esvaziamento da bolsa duodenojejunal em doentes submetidos a gastrectomia total com reconstrução à Safatle. MÉTODO: Foram estudados 12 doentes submetidos a gastrectomia total por câncer gástrico com reconstrução à Safatle, convocados para realizar radiografias contrastadas de esôfago-duodeno-jejuno pelo método videofluoroscópico nos meses de julho a agosto de 2005. RESULTADOS: Todos os doentes apresentaram motricidade satisfatória da bolsa duodenojejunal com adequado esvaziamento em antiperistalse sem estase alimentar. O tempo de esvaziamento da bolsa duodenojejunal foi de 25 minutos em média. CONCLUSÃO: A bolsa duodenojejunal, nos doentes submetidos a gastrectomia total com reconstrução à Safatle, apresentou adequado esvaziamento e motricidade.

Evaluation of ligamentum teres hepatis with multi-slice spiral CT:an initial experience / 中国普通外科杂志

Objective To recognize the features of the ligamentum teres hepatic(LTH) in multi-slice spiral CT,and to preliminarily explore its clinical value.Methods A total of 130 patients without liver disease underwent abdominal scanning with a 16-slice spiral CT scanner.LTHs,as focused points,were observed by using postprocessing techniques such as multi-planar reformation(MPR),slab maximum intensity projection(slab-MIP) and slab volume rendering(slab-VR).Results The LTH was detected by multi-slice spiral CT in 90.8%(118/130).On these oblique-sagittal MPR,slab-MIP and slab-VR images,LTH presentedas slightly high density smooth cord-like structure in accordance with its anatomical morphology and position.The mean diameter of fissure portion of normal LTH was(5.44?0.96) mm(range 3.2-7.2 mm) measured at its middle region,and that of free portion of normal LTH was(3.43?0.91) mm(range 1.6-6.0 mm).Conclusions Multi-slice spiral CT demonstrates the LTH clearly,and has a potentialto evaluate the LTH before abdominal operation in which the LTH is to be used as an autogenous repairmaterial.
