Caracterización clinicoepidemiológica, diagnóstica e histopatológica de pacientes tratados con esofagectomía por cáncer de esófago / Clinical epidemiological, diagnostic, histological and pathological characterization of patients treated with esophagectomy due to esophagus cancer

Introducción: El cáncer de esófago se manifiesta clínicamente en etapas avanzadas y presenta gran letalidad. Objetivo: Caracterizar a los pacientes operados de cáncer de esófago según variables epidemiológicas, clínicas, diagnósticas e histopatológicas. Métodos: Se realizó un estudio observacional, descriptivo y transversal de 87 pacientes con cáncer de esófago, operados en el Servicio de Cirugía General del Hospital Provincial Docente Clinicoquirúrgico Saturnino Lora de Santiago de Cuba, en el periodo 2014-2018. Resultados: Dicha afección predominó en pacientes del sexo masculino (94,2 %) entre los 65 y 74 años de edad (37,9 %); el tipo histológico más frecuente fue el carcinoma epidermoide (89,6 %) y la localización en el tercio medio (49,4 %). Los hábitos tóxicos que primaron fueron el tabaquismo (87,4 %) y el consumo de alcohol (75,8 %). La disfagia y la pérdida de peso se manifestaron en 73,5 y 66,6 % de la serie, respectivamente. El diagnóstico se realizó mediante imágenes, tales como esofagograma, tomografía contrastada de tórax, abdomen y pelvis; así como por medio de endoscopia y biopsia. Conclusiones: Se demostró que los hombres son los más afectados y es más frecuente el diagnóstico en mayores de 60 años de edad. Se observó el vínculo con el hábito de fumar y el consumo de alcohol. La disfagia es el síntoma más común y tardío de la enfermedad. El estudio de las características clínico-histológicas de los pacientes con cáncer de esófago permite un adecuado enfoque diagnóstico de esta afección, así como el desarrollo de acciones de salud preventivas sobre los principales factores de riesgo identificados.

Introduction: The esophagus cancer is clinically manifested in advanced stages and presents great lethality. Objective: To characterize the patients operated on esophagus cancer according to epidemiological, clinical, diagnostic, histological and pathological variables. Methods: An observational, descriptive and cross-sectional study of 87 patients with esophagus cancer was carried out; they were operated in the General Surgery Service of Saturnino Lora Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba, in the period 2014-2018. Results: This affection prevailed in patients from the male sex (94.2 %) between the 65 and 74 years (37.9 %); the most frequent histhologic type was the squamous cell carcinoma (89.6 %) and the localization in the mean third (49.4 %). The toxic habits that prevailed were nicotine addiction (87.4 %) and consumption of alcohol (75.8 %). The dysphagia and loss of weight showed in 73.5 and 66.6 % of the series, respectively. The diagnosis was carried out by means of images, such as esophagogram, chest, abdomen and pelvis contrast tomography, as well as by means of endoscopy and biopsy. Conclusions: It was demonstrated that men are the most affected and it is more frequent the diagnosis in those over 60 years. The link with the habit of smoking and consumption of alcohol was observed. The dysphagia is the most common and late symptom of the disease. The study of clinical, histological and pathological characteristics of patients with esophagus cancer allows an appropriate diagnostic approach of this affection, as well as the development of preventive health actions about the main identified risk factors.

Acalasia y su relación con el cáncer esofágico / Esophageal acalasia and its relationship with esophageal cancer

Resumen La acalasia es un trastorno motor primario de la musculatura lisa esofágica que se caracteriza por disfagia, pseudorregurgitación y baja de peso. El tratamiento puede ser endoscópico o quirúrgico. Sólo se conocen los resultados a largo plazo de la cirugía, mientras que los endoscópicos tienen aún un seguimiento muy corto y no permiten sacar conclusiones valederas. La acalasia es una lesión que tiene una probabilidad significativamente mayor de desarrollar un cáncer esofágico, ya sea de tipo epidermoide, por inflamación crónica y retención de comida en el esófago, o un adenocarcinoma, secundario a reflujo gastroesofágico, que aparece posterior a cualquier tratamiento. Las publicaciones muestran que alrededor de 3% a 4% de los pacientes presentan a largo plazo, sobre 10 a 15 años postratamiento, el desarrollo de un cáncer avanzado del esófago. Se concluye que es indispensable un seguimiento clínico y endoscópico en forma rutinaria a estos pacientes.

Achalasia is a primary motor disorder of the esophageal smooth muscle characterized by dysphagia, pseudoregurgitation, and weight loss. Treatment can be endoscopic or surgical. The long-term results are only known from surgery, while endoscopic results still have a very short follow-up and do not allow us to draw valid conclusions. Achalasia is a lesión that has a significantly higher probability of developing esophageal cancer, whether of the epidermoid type, due to chronic inflammation and food retention in the esophagus, or an adenocarcinoma, secondary to gastroesophageal reflux, which appears after any treatment. Publications show that about 3 to 4% of patients present in time, about 10 to 15 years after treatment, the development of advanced cancer of the esophagus. It is concluded that clinical and endoscopic follow-up is essential in these patients on a routine basis.

Esôfago de Barrett: o estado da arte / Barrett's Esophagus: the state of the art

Objetivo: Demonstrar fatores envolvidos nos distúrbios do sono em profissionais que fazem plantões. Métodos: Trata-se de estudo transversal, cuja amostra foi composta de 244 voluntários, plantonistas da área da saúde, sendo 191 do sexo feminino, que responderam a um questionário socioeconômico, associado à aplicação da Escala de Sonolência de Epworth e ao Índice de Qualidade do Sono de Pittsburgh. Os dados foram analisados pelos coeficientes de Spearman e de Kendall Tau, com distribuição de probabilidade gama. Resultados: Houve significância (p<0,05) com o Índice de Qualidade do Sono de Pittsburgh e a atividade física (+0,216), ergonomia (+0,148), filhos (-0,146), valor da remuneração (+0,112) e disfunção durante o dia (+0,352). Também houve significância com a Escala de Sonolência de Epworth e atividade física (+0,138), renda familiar (-0,118), trabalho semanal (-0,151), latência do sono (-0,106), duração do sono (-0,107), eficiência do sono (-0,139) e disfunção durante o dia (+0,170). Por fim, a eficiência do sono teve significiância com profissão (-0,209), tabagismo (+0,402), Escala de Sonolência de Epworth (-0,139) e dissonias com a obesidade (índice de massa corporal >30; razão de chance de 1,40; intervalo de confiança de 95% de 1,02-1,94). Conclusão: As medidas autorrelatadas são prontamente obtidas com questionários validados, como a Escala de Sonolência de Epworth e o Índice de Qualidade do Sono de Pittsburgh, encontrando-se correlações com renda familiar, ter ou não filhos, índice de massa corporal, atividade física, ergonomia, condições de trabalho, tabagismo e componentes biopsicossociais. Em virtude do caráter transversal deste estudo é indispensável mais estudos com maior follow-up

Objective: To demonstrate factors involved in sleep disorders in professionals who take shifts. Methods: This is a cross-sectional study whose sample consists of 244 volunteers, on-duty health workers, 191 females, who answered a socioeconomic questionnaire, associated with application of the Epworth Sleepiness Scale and the Pittsburgh Sleep Quality Index. Data were analyzed with Spearman's and Kendall Tau coefficients, and gamma probability distribution. Results: There was significance (p<0,05) with the Pittsburgh Sleep Quality Index and physical activity (+0,216), ergonomics (+0,148), children (-0,146), the wage (+0,112), dysfunction during the day (+0,352). Also there was significance with the Epworth Sleepiness Scale and physical activity (+0,138), family income (-0,118), weekly workload (-0,151), sleep latency (-0,106), sleep duration (-0,107), sleep efficiency (-0,139), and dysfunction during the day (+0,170). Finally, sleep efficiency was significant with occupation (-0,209), smoking habits (+0,402), Epworth Sleepiness Scale (-0,139), dyssomnia with obesity (body index mass >30; OR of 1,40; CI 95% 1,02-1,94). Conclusion: Self-reported measures are readily obtained with validated questionnaires such as Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index, with correlations with family income, having children or not, body mass index, physical activity, ergonomics, working conditions, smoking habits, and biopsychosocial components. Due to the cross-sectional nature of this study, further research with longer follow-up is indispensable

Caracterización clínico-patológica del cáncer esofágico avanzado en el Hospital Universitario Comandante Faustino Pérez. Matanzas / Clinic-pathologic characterization of the advanced esophagus cancer in the University Hospital Comandante Faustino Perez, Matanzas

RESUMEN Introducción: el cáncer de esófago en estadio avanzado, es uno de los más agresivos. En Cuba ocupa el décimo lugar entre las causas de muerte. Objetivo: caracterizar clínico y patológicamente a los pacientes con cáncer esofágico diagnosticados en el hospital estudiado. Materiales y métodos: se realizó un estudio prospectivo-descriptivo donde se efectuó una caracterización clínico-patológica a 59 pacientes con el diagnóstico endoscópico e histológico de cáncer de esófago, en el Hospital Faustino Pérez Hernández de Matanzas, de enero del 2016 a diciembre del 2017. Se estudiaron variables como: grupo etáreo, sexo, antecedentes patológicos personales y familiares, factores de riesgo, síntomas y signos predominantes en el diagnóstico, tiempo de aparición de los síntomas, tipo endoscópico, localización, tipo histológico, grado de diferenciación histológica, estadio de la enfermedad, tipo de tratamiento y tiempo de vida posterior al diagnóstico. Resultados: predominó el sexo masculino (88.1%) en pacientes mayores de 60 años (52.6%). La disfagia, la astenia y la anorexia fueron los síntomas más frecuentes; el etilismo crónico y el hábito de fumar fueron los factores de riesgo predominantes. La localización anatómica más frecuente fue el tercio medio (54.2%), el tipo endoscópico vegetante (88.1%) y el tipo histológico carcinoma epidermoide bien diferenciado (55.9%). Hubo relación entre el tiempo de inicio de los síntomas entre 3 y 6 meses antes del diagnóstico y el estadio IV de la enfermedad que predominó en 29 pacientes (49.2%). La mayoría de los pacientes recibieron tratamiento oncológico combinado con cirugía paliativa (47.5%) o ningún tratamiento (45.8%) pues el 50.8% de los pacientes fallecieron al mes del diagnóstico demostrando que el diagnóstico del cáncer esofágico se realiza casi siempre en estadios avanzados de la enfermedad cuando son posible pocas opciones terapéuticas. Conclusiones: el cáncer de esófago aún sigue diagnosticándose de forma tardía en estadios avanzados, con elevada prevalencia del carcinoma epidermoide sobre el adedocarcinoma que indica pocas acciones de salud preventivas sobre los factores de riesgo en la población estudiada, existiendo relación entre el estadio avanzado de la enfermedad y el poco tiempo de vida de estos pacientes posterior al diagnóstico.

ABSTRACT Introduction: the advanced-stage esophagus cancer is one of the most aggressive cancers. In Cuba, it is in the tenth place among the death reasons. Objective: to clinically and pathologically characterize the patients with esophageal cancer diagnosed in the mentioned hospital. Materials and methods: a prospective-descriptive study was carried out based on the clinical-histological characterization of 59 patients with the endoscopic and histological diagnosis of esophageal cancer in the Hospital "Faustino Pérez Hernández", of Matanzas, in the period from January 2016 to December 2017. The studied variables were: age group, sex, personal and familiar pathological antecedents, risk factors, symptoms and signs that were predominant in the diagnosis, time passed since the symptoms appeared, endoscopic kind, location, histological kind, level of histological differentiation, disease stage, kind of treatment, and life time after the diagnosis. Results: male sex predominated (88.1 %) in patients older than 60 years (52.6 %). Dysphagia, asthenia and anorexia were the most frequent signs. Alcoholism and smoking were the predominant risk factors. The most frequent anatomic location was the middle third (54.3 %); the endoscopic vegetating kind (88.1 %) and the histological kind well-differentiated epidermoid carcinoma (55.9 %) prevailed. The authors found a relation between the beginnings of the symptoms 3 to 6 months before the diagnosis and the disease IV stage predominating in 29 patients (49.2 %). Most of patients underwent oncologic treatment combined with palliative surgery (47.5 %) or no treatment (45.8 %), because 50.8 % of the patients died a month after the diagnosis, showing that the diagnosis of esophageal cancer is almost always achieved at advanced stages of the disease, when few therapeutic options are possible. Conclusions: esophageal cancer is still being diagnosed late, in advanced stages, with a higher prevalence of the epidermoid carcinoma over the adenocarcinoma. It indicates few health preventive actions on the risk factors among the studied population. There is a relation between the disease advanced stage and the few time patients live after the diagnosis.

Carcinoma neuroendocrino de esófago: reporte de caso / Neoendocrine carcinoma of the esophagus: report of a case

El carcinoma neuroendocrino de esófago representa menos del 2% de casos de cáncer de esófago. Esta forma de presentación es extremadamente inusual, ya que este tipo de carcinoma se suele presentar con mayor frecuencia en zonas broncopulmonares. Los síntomas suelen asociarse a la obstrucción esofágica e incluyen odinofagia, disfagia y pérdida de peso, siendo infrecuente la clínica de síndrome carcinoide. Para el diagnóstico se requiere de uno o más de los siguientes marcadores de inmunohistoquímica positivos: cromogranina A, sinaptofisina o CD56 positivos, así como la presencia de los anticuerpos EMA y PANCK positivos. Se reporta el caso de un paciente varón con diagnóstico de tumor neuroendocrino de esófago.

Neuroendocrine carcinoma of esophagus represents less than 2% of cases of cancer of the esophagus. This presentation is extremely unusual, as this type of carcinoma typically presents with greater frequency in bronchopulmonary regions. The symptoms are usually associated with esophageal obstruction and include odynophagia, dysphagia and weight loss and are not usually associated with Carcinoid syndrome. The diagnosis requires one or more of the following positive immunohistochemical markers: Chromogranin A, synaptophysin or CD56 positive, as well as the presence of EMA and PANCK positive. We report the case of a male patient with diagnosis of neuroendocrine tumor of esophagus.

Melanoma maligno primario atípico de esófago y su manejo quirúrgico: a propósito de un caso clínico / Atypical primary malignant melanoma of esophagus and the surgical management: Case report

Resumen Introducción El melanoma maligno primario de esófago es un tumor raro y muy agresivo. De manejo controversial, el tratamiento quirúrgico es el que predomina en enfermedad localizada. Caso clínico Presentamos el caso de una mujer joven con melanoma maligno primario de esófago de presentación atípica y su manejo quirúrgico utilizando la técnica de Akiyama.

Introduction The Primary Malignant Melanoma of Esophagus is an uncommon and very agressive tumor. With controversial management, it predominates the surgical treatment in localized disease. Clinical case We present the case of a young women with Primary Malignant Melanoma of Esophagus with atypical presentation and its surgical management using the Akiyama technique.

Disección endoscópica submucosa en el tratamiento del cáncer precoz de esófago / Submucosal endoscopic dissection in the treatment of early esophageal cancer

Reportamos el caso de un paciente masculino, 80 años, con historia de dispepsia y sin antecedente familiar de neoplasias. En la endoscopia digestiva alta, en tercio distal, se observó una lesión deprimida plana con aspecto de carcinoma precoz IIC que fue diagnosticada por biopsia como carcinoma escamoso in situ e infiltrante, no queratinizante moderadamente diferenciado grado II. Fue sometido a disección endoscópica submucosa, sin complicaciones. La histopatología concluyo: carcinoma de células escamosas, predominantemente in situ de esófago distal, midiendo 0,6 cm, con foco de 0,1 cm de infiltración en la lámina propia; ausencia de invasión neoplásica angiolinfática o perineural con márgenes de resección quirúrgica libre de neoplasia. Estadio pT1a. Tres meses después, en la endoscopia de control con toma de biopsias de la zona, no hubo evidencia de carcinoma. Presentamos el caso debido a que sigue siendo todo un reto establecer el diagnóstico de cáncer de esófago en etapa temprana, sobre todo en pacientes poco sintomáticos, resaltando la importancia de la cromoendoscopia y de una buena exploración endoscópica para llegar al diagnóstico. La disección endoscopia submucosa podría considerarse como un tratamiento alternativo seguro y eficaz a la cirugía radical.

We report the case of a male patient, 80 years old, with a history of dyspepsia and no family history of neoplasias. In the upper digestive endoscopy in the distal esophagus, a flat depressed lesion with the appearance of early carcinoma, type IIC of Paris classification, was diagnosed by biopsy as a squamous carcinoma in situ, infiltrating, moderately differentiated non-keratinizing grade II carcinoma. He underwent submucosal endoscopic dissection without complications. Histopathology concluded: carcinoma of squamous cells, predominantly in situ of distal esophagus, measuring 0.6 cm, with focus of 0.1 cm of infiltration in the own lamina; absence of angiolymphatic or perineural invasion. The histopathology specimen had margins of surgical resection free of neoplasia. Stage pT1a. Three months later, in the endoscopy control with biopsy of the area, there was no evidence of carcinoma. We present the case because it is still a challenge to establish the diagnosis of esophageal cancer at an early stage, especially in patients without symptoms, highlighting the importance of chromoendoscopy and a good endoscopic examination to reach the diagnosis. Submucosal endoscopy dissection could be considered as a safe and effective alternative treatment to radical surgery.

Endoscopic surveillance of extensive esophageal papillomatosis not amenable to endoscopic therapy / Controle endoscópico de papilomatose esofágica extensa sem indicação para tratamento endoscópico

ABSTRACT We present two cases of esophageal papillomatosis, a very rare reported disease leading to dysphagia and did not improve after endoscopic treatment. Both patients refused surgery and they were followed-up for 3 years, but no significant clinical or endoscopic changes were seen.

RESUMO Apresentamos dois casos de papilomatose esofágica, lesão raramente relatada, que pode levar à disfagia, e que não teve melhora após tratamento endoscópico. Ambos os pacientes recusaram cirurgia e foram acompanhados por até 3 anos, sem alterações clínicas ou endoscópicas importantes.

Cromoscopia vital com Lugol versus cromoscopia óptica na detecção de câncer de esôfago em pacientes com estenoses cáusticas esofagianas / Lugol's iodine chromoendoscopy versus narrow band image enhanced endoscopy for the detection of esophageal cancer in patients with stenosis secondary to caustic/corrosive agent ingestion

ABSTRACT BACKGROUND The diagnosis of corrosion cancer should be suspected in patients with corrosive ingestion if after a latent period of negligible symptoms there is development of dysphagia, or poor response to dilatation, or if respiratory symptoms develop in an otherwise stable patient of esophageal stenosis. Narrow Band Imaging detects superficial squamous cell carcinoma more frequently than white-light imaging, and has significantly higher sensitivity and accuracy compared with white-light. OBJECTIVE To determinate the clinical applicability of Narrow Band Imaging versus Lugol´s solution chromendoscopy for detection of early esophageal cancer in patients with caustic/corrosive agent stenosis. METHODS Thirty-eight patients, aged between 28-84 were enrolled and examined by both Narrow Band Imaging and Lugol´s solution chromendoscopy. A 4.9mm diameter endoscope was used facilitating examination of a stenotic area without dilation. Narrow Band Imaging was performed and any lesion detected was marked for later biopsy. Then, Lugol´s solution chromoendoscopy was performed and biopsies were taken at suspicious areas. Patients who had abnormal findings at the routine, Narrow Band Imaging or Lugol´s solution chromoscopy exam had their stenotic ring biopsied. RESULTS We detected nine suspicious lesions with Narrow Band Imaging and 14 with Lugol´s solution chromendoscopy. The sensitivity and specificity of the Narrow Band Imaging was 100% and 80.6%, and with Lugol´s chromoscopy 100% and 66.67%, respectively. Five (13%) suspicious lesions were detected both with Narrow Band Imaging and Lugol's chromoscopy, two (40%) of these lesions were confirmed carcinoma on histopathological examination. CONCLUSION Narrow Band Imaging is an applicable option to detect and evaluate cancer in patients with caustic /corrosive stenosis compared to the Lugol´s solution chromoscopy.

RESUMO CONTEXTO A suspeita do câncer de esôfago na lesão cáustica ocorre quando os pacientes com estenoses previamente estáveis, após um período latente sem sintomas, apresentam disfagia, baixa resposta as dilatações ou sintomas respiratórios. A cromoscopia com luz de banda estreita detecta o câncer superficial de esôfago mais frequentemente que a luz branca, com alta sensibilidade e acurácia. OBJETIVO Determinar a aplicabilidade clínica da luz de banda estreita versus a cromoscopia vital com Lugol na detecção do câncer precoce de esôfago em pacientes com lesões cáusticas. MÉTODOS Um total de 38 pacientes, entre 28 e 84 anos, foram alocados seguidamente e submetidos à cromoscopia com luz de banda estreita e com Lugol. Um gastroscópio de 4,9 mm de diâmetro foi usado para facilitar o exame da área estenosada, sem necessidade de dilatação. A cromoscopia com luz de banda estreita era realizada primeiro e as áreas suspeitas anotadas. Depois, a cromoscopia com Lugol era realizada e as áreas suspeitas biopsiadas. RESULTADOS Detectamos nove lesões suspeitas com a luz de banda estreita e 14 com o Lugol. A sensibilidade e especificidade da cromoscopia com luz de banda estreita foi de 100% e 80,6%, e a do Lugol foi de 100% e 66,67% respectivamente. Cinco (13%) lesões suspeitas foram detectadas coincidentemente pelos dois métodos, sendo duas (40%) com diagnóstico anatomopatológico de câncer de esôfago. CONCLUSÃO A cromoscopia com luz de banda estreita é opção concreta para o diagnóstico de câncer em pacientes com estenoses esofágicas por corrosões cáusticas, comparado a cromoscopia com Lugol.

Neoplasia de Esôfago / Esophageal Neoplasm

Objetivos: Apresentar uma atualização naepidemiologia, apresentação clínica, diagnóstico e conduta terapêutica do paciente com neoplasia esofágica. Métodos: Revisão da literaturareferente à neoplasia de esôfago por meio de pesquisa no PubMed, de artigos publicados durante o período de 2013 a 2017,e no site do Instituto Nacional do Câncer (INCA). Resultados: O câncer de esôfago vem aumentando sua incidência nos últimos anos. O tipo histológico mais comum no mundo é o carcinoma de células escamosas (CCE), seguido pelo adenocarcinoma. Os principais fatores de risco são tabagismo e alcoolismo para o CCE; e doença do refluxo gastroesofágico e obesidade para adenocarcinoma. A apresentação clínica inclui disfagia progressiva, perda de peso e astenia; sendo mais característicos de estágios avançados. O diagnóstico é feito por endoscopia digestiva alta e biópsia. O estadiamento, com base no TNM, compreende ultrassonografia endoscópica (EUS), tomografia (TC) de tórax e abdome com contraste e tomografia por emissão de pósitrons (PET-CT). A escolha do tratamento depende do estágio da doença. Conclusões: A melhora da acurácia do estadiamento, surgimento de novas drogas oncológicas, evolução da radioterapia e técnicas cirúrgicas permitiu uma melhora na sobrevida nas últimas décadas. Entretanto, mais estudos são necessários nesta área, sobretudo com ênfase em marcadores tumorais.

Aims: Esophageal cancer update on epidemiology, clinical presentation, diagnosis and therapy. Methods: Esophageal cancer literature review on PubMed and on the website of the National Cancer Institute (INCA). Results: Esophageal cancer has increased its incidence in recent years. The most common histological type worldwide is squamous cell carcinoma (SCC), followed by adenocarcinoma. The main risk factors are: smoking and alcoholism for SCC; and gastroesophageal reflux disease and obesity for adenocarcinoma. Clinical presentation includes progressive dysphagia, weight loss, and asthenia; however, they are more characteristic in advanced stages. Diagnosis is made through a esophagogastroduodenoscopy (EGD) and biopsy. Staging, based on TNM, includes endoscopic ultrasonography, thorax and abdominal CT-Scan and PET-CT. The choice of treatment depends on the stage of the disease. Conclusions: The advance in diagnosis accuracy, newly oncologic drugs, radiotherapy and surgical techniques was responsible for survival improvement in recent decades. However, more studies are needed in this area, especially with an emphasis on tumor markers.

Esophageal Squamous Cell Carcinoma Patients Have an Increased Risk of Coexisting Colorectal Neoplasms

BACKGROUND/AIMS: Esophageal squamous cell carcinoma (ESCC) and colorectal neoplasms (CRNs) share risk factors. We aimed to investigate whether the CRN risk is increased in ESCC patients. METHODS: ESCC patients who underwent a colonoscopy within 1 year of diagnosis were retrospectively analyzed. Patients were matched 1:3 by age, gender, and body mass index to asymptomatic controls. CRN was defined as the histological confirmation of adenoma or adenocarcinoma. Advanced CRN was defined as any of the following: > or =3 adenomas, high-grade dysplasia, villous features, tumor > or =1 cm, or adenocarcinoma. The risk factors for both CRN and advanced CRN were evaluated by univariate and multivariate analyses. RESULTS: Sixty ESCC patients were compared with 180 controls. The ESCC group had significantly higher numbers of CRNs (odds ratio [OR], 2.311; 95% confidence interval [CI], 1.265 to 4.220; p=0.006) and advanced CRNs (OR, 2.317; 95% CI, 1.185 to 4.530; p=0.013). Significant risk factors for both CRN and advanced CRN by multivariate analysis included ESCC (OR, 2.157, 95% CI, 1.106 to 4.070, p=0.024; and OR, 2.157, 95% CI, 1.045 to 4.454, p=0.038, respectively) and older age (OR, 1.068, 95% CI, 1.032 to 1.106, p<0.001; and OR, 1.065, 95% CI, 1.024 to 1.109, p=0.002, respectively). CONCLUSIONS: The rates of CRN and advanced CRN are significantly increased in ESCC. Colonos-copy should be considered at ESCC diagnosis.

Guía de práctica clínica para la enfermedad por reflujo gastroesofágico / Clinical practice guideline for disease caused by gastroesophageal reflux

Objetivo: brindar una guía de práctica clínica basada en la evidencia más reciente para el diagnóstico y tratamiento del reflujo gastroesofágico teniendo en cuenta la efectividad y seguridad de las intervenciones dirigidas a pacientes, personal asistencial, administrativo y entes gubernamentales de cualquier servicio de atención en Colombia. Materiales y métodos: esta guía fue desarrollada por un equipo multidisciplinario con apoyo de la Asociación Colombiana de Gastroenterología, el Grupo Cochrane ITS y el Instituto de Investigaciones Clínicas de la Universidad Nacional de Colombia. Se desarrollaron preguntas clínicas relevantes y se realizó la búsqueda de guías nacionales e internacionales en bases de datos especializadas. Las guías existentes fueron evaluadas en términos de calidad y aplicabilidad; 1 guía cumplió los criterios de adaptación, por lo que se decidió adaptar 3 preguntas clínicas. El Grupo Cochrane realizó la búsqueda sistemática de la literatura. Las tablas de evidencia y recomendaciones fueron realizadas con base en la metodología GRADE. Las recomendaciones de la guía fueron socializadas en una reunión de expertos con entes gubernamentales y pacientes. Resultados: se desarrolló una guía de práctica clínica basada en la evidencia para el diagnóstico y tratamiento de pacientes con reflujo gastroesofágico en Colombia. Conclusiones: el diagnóstico y manejo oportuno de los pacientes con ERGE contribuirá a disminuir la carga de la enfermedad en Colombia, así como de las enfermedades asociadas.

Objective: To provide a clinical practice guideline with the latest evidence for diagnosis and treatment of gastroesophageal reflux for patients, caregivers, administrative and government bodies at all levels of care in Colombia. Materials and Methods: This guide was developed by a multidisciplinary team with the support of the Colombian Association of Gastroenterology, Cochrane STI Group and Clinical Research Institute of the Universidad Nacional de Colombia. Relevant clinical questions were developed and the search for national and international guidelines in databases was performed. Existing guidelines were evaluated quality and applicability. One guideline met the criteria for adaptation, so the group decided to adapt 3 clinical questions. Systematic literature searches were conducted by the Cochrane Group. The tables of evidence and recommendations were made based on the GRADE methodology. The recommendations of the guide were socialized in a meeting of experts with government agencies and patients. Results: An evidence-based Clinical Practice Guidelines for the diagnosis and treatment of gastroesophageal reflux was developed for the Colombian context. Conclusions: The opportune detection and appropriate management of gastroesophageal reflux would contribute to the burden of the disease in Colombia and its associated diseases.

Differential Diagnosis and Treatment of Isolated Pathologies of the Sphenoid Sinus: Retrospective Study of 46 Cases

Introduction Isolated disease of the sphenoid is rare and has often been overlooked due to its remote location and difficult access. Objective A retrospective study of the main causes of isolated sphenoid sinus diseases with discussion of the most appropriate methods of diagnosis and treatment. Methods A total of 46 cases of isolated sphenoid disease treated between January 2008 and December 2013 were evaluated by objective ear, nose, and throat examination and video endoscopy, computed tomography of the paranasal sinuses, and, in some cases, magnetic resonance imaging. In each case, we decided between drug and/or endoscopic treatment. Results We identified 12 cases of isolated sphenoiditis (26.1% ), 3 cases of fungal sphenoiditis (6.5% ), 3 cases of sphenochoanal polyps (6.5% ), 22 cases of mucocele (47.8% ), 2 cases of cerebrospinal fluid leak (4.3% ), and 1 case each of meningoencephalocele (2.1% ), inverted papilloma (2.1% ), fibrous dysplasia (2.1% ), and squamous cell carcinoma (2.1% ). Conclusion A prevalence of inflammatory and infectious diseases was found, and endoscopic surgery for the sphenoid sinus approach is effective in treating various diseases of the isolated sphenoid, whether complicated or not. .

Esophageal Cancer Initially Presenting as Severe Paraneoplastic Hypercalcemia Requiring Hemodialysis / 대한소화기학회지

Paraneoplastic hypercalcemia without bone metastasis occurs rarely in esophageal cancer. A 75-year-old man was admitted for general weakness and lethargy. Laboratory data showed high serum calcium level (corrected calcium 14.6 mg/dL), low parathyroid hormone level (3.3 pg/mL) and high parathyroid hormone-related peptide level (3.5 pmol/L). Esophagogastroscopy showed a malignant tumor in the esophagus. Histology showed moderately differentiated squamous cell carcinoma. Bone scan showed no evidence of bone metastasis. Since the patient's calcium levels remained high and mental state did not show improvement despite intravenous fluid therapy, diuretics and intravenous bisphosphonate, hemodialysis was started. After hemodialysis treatment, the serum calcium level subsequently normalized and his mental status improved. Herein, we report a rare case of paraneoplastic hypercalcemia in a patient with esophageal cancer.
