ABSTRACT

Introducción: La endoscopia estándar no diagnostica gastritis histológica y requiere biopsia para confirmarla. Con magnificación se observan micro estructuras que sugieren su presencia. Objetivo: Diagnosticar gastritis histológica en el cuerpo gástrico según el patrón de mucosa identificado con magnificación y “Flexible Spectral Imaging Colour Enhancement” (FICE). Pacientes: Previo consentimiento se incluyeron a los individuos con indicación electiva de endoscopia digestiva superior. Materiales y Métodos: Se realizó endoscopia digestiva superior con equipo Fujinon Inc. EG 590 ZW, y el procesador EPX 4400. En ambas caras del cuerpo gástrico se realizó consecutivamente: a) alta resolución, b) magnificación, c) alta resolución, d) efecto FICE, e) magnificación, f) alta resolución y g) biopsias de ambas caras del cuerpo evaluadas por los patólogos sin información clínica. Todo el procedimiento se grabó, se fotografió y se guardó en JPEG en programa Power Point. Resultados: Se evaluaron 60 áreas en 30 pacientes: 10 hombres y 20 mujeres con edades de 23-82 años y promedio 49,60 años. Solo la magnificación identificó los patrones de mucosa gástrica que se resaltaron con FICE. No se corroboró gastritis histológica en patrón Z0 pero sí en todas las áreas con Z2 y Z3. Conclusión: El patrón de mucosa en cuerpo gástrico observado con magnificación y FICE diagnostica gastritis histológica.


Introduction: Standard endoscopy requires biopsy to diagnose histological gastritis. Gastric mucosa micro structures are observed with magnification suggesting its presence. Objective: Diagnosing histological gastritis in the gastric body according to the mucosal pattern identified with magnification and "Flexible Spectral Imaging Colour Enhancement" (FICE). Patients: Individuals scheduled to undergo routine upper gastrointestinal endoscopy were enrolled. Materials and methods: Upper gastrointestinal endoscopy was performed with Fujinon Inc. 590 EG ZW and EPX 4400 processor. On both sides of the gastric corpus endoscopy was performed consecutively with: a) high-resolution, b) magnification, c) high resolution d) FICE, e) magnification, f) high resolution and g) biopsies of both sides of the body evaluated by pathologists without clinical information. The entire procedure was recorded, was photographed and was saved in JPEG in program Power Point. Results: 60 areas in 30 patients were evaluated: 10 men and 20 women with ages of 23-82 years and average 49.60. Only magnification identified patterns of gastric mucosa and they were highlighted with FICE. Histological gastritis was found in all identified Z2 and Z3 areas but none in Z0 pattern. Conclusion: The pattern of mucosa in gastric body observed with magnification and FICE diagnosed histological gastritis.

ABSTRACT

Las lesiones planas están asociadas con mayor frecuencia a la presencia de carcinoma invasor superficial. La magnificación endoscópica permite el análisis detallado de la superficie mucosa de lesiones sospechosas y predecir, por sus características morfológicas, si son lesiones benignas o malignas, permitiendo decidir conducta terapéutica al momento del estudio. Los tumores de diseminación lateral de colon y recto, son lesiones >10mm con bajo eje vertical extendidas lateralmente a lo largo de la pared luminal. Okamoto describe dos grupos: tipo granular, endoscópicamente numerosos nódulos de color homogéneo en comparación con mucosa colónica circundante; tipo plano, lesiones con superficie plana en ausencia de formación de gránulos nodulares. Establecer utilidad de la cromoendoscopia virtual computarizada y magnificación (FICE) para la determinación de las lesiones detectadas en estudios de video colonoscopia; decidir en el momento del procedimiento, la conducta a seguir. Se utilizó el modelo de clasificación de Paris en las lesiones colorectales detectadas. Estudio retrospectivo y descriptivo en pacientes que acudieron a una consulta de centro privado, en el período Enero 2009-Marzo 2012, realizándoles video colonoscopia con FICE, con equipo Fujinon EPX-4400, por un mismo endoscopista. Se revisaron 1298 video colonoscopias, 269 casos con lesiones planas en colon de los cuales 17 (6.31%) fueron lesiones tipo II (diseminación lateral); 9 del sexo femenino (52.94%) y 8 masculino (47.05%); 7 fueron lesiones IIa no granular (41.17%), 7 IIa granular (41.17%), 2 IIc no granular (11.76%) y 1 IIc granular (5.88%). En relación a la ubicación 5 casos (29.41%), en transverso; 4 casos (23.52%) tuvieron resección endoscópica y 13 casos (76.47%) fueron referidos para resolución quirúrgica de los cuales, histológicamente: 7 fueron tubulovellosos (41,18%) y 1 de estos presentó displasia de alto grado y los 6 restantes de bajo grado....


The flat lesions are associated with a high incidence of invasive superficial carcinoma; the endoscopic magnification allows a more detailed evaluation of the superficial lesions and can predict if they will be or not malignant, allowing to take a therapeutic decision at the moment of the videocolonoscopy. These tumours are lesions no more than 10 mm, whit a low vertical axis wich extents laterally along the lumen of the colon. Okamoto describes two groups: Granular type Endoscopically are numerous nodules with the same color compared with the surrounding colonic mucosae; and the Flat type which are flat lesions without presence of nodules. To establish the utility of the virtual computerized chromoendoscopy and magnification (FICE)® in the evaluation of lesions detected in videocolonoscopies performed and in order to take a therapeutic decision. We used the Paris model for the classification of the colorectal lesions encountered at the time of the colonoscopy. We performed a retrospective and descriptive study in patients who evaluated in a private office between January 2009-March 2012, a videcolonoscopy with FICE® using a videocolonoscope Fujinon EPX 4400 ® all studies were performed by the same operator. 1298 videocolonoscopies were performed, 269 cases with flat lesions, 17 (6.31%) were lesions type II (lateral spread), 9 were females (52,94%) and 8 males (47,05%), 7 were lesions type IIa, non granular (41,17%), 7 IIa granular (41,17%), 2 IIc non granular (11,76%), and 1 IIc granular (5,88%), 5 cases (29,41%) were located in transverse colon, 4 (23,52%) were successfully removed endoscopically , and 13 (76,47) were referred for surgical treatment, in relation with the histopathology: 7 were tubulovillous (41,18%), and 1 associated with high degree dysplasia and 6 low degree dysplasia. Our study demonstrates, the usefulness of the FICE® in the detection of flat lesions and permits obtain samples for biopsy and make therapeutic decisions

ABSTRACT

La endoscopia estándar no identifica esófago de Barrett. Esta limitación disminuye con magnificación endoscópica, coloración vital y/o virtual que permite observar los patrones de mucosa sugestivos de metaplasia intestinal. Identificar metaplasia intestinal con magnificación endoscópica y cromoscopia virtual realizada con "Flexible Spectral Imaging Colour Enhancement" (FICE) corroborándola con histología. Pacientes: Previo consentimiento se incluyeron a los individuos con indicación electiva de endoscopia digestiva superior. Se realizó endoscopia digestiva superior con equipo Fujinon Inc. EG 590 ZW, y procesador EPX 4400. Consecutivamente se practicó endoscopia con: a) alta resolución, b) FICE, c) alta resolución, d) magnificación, e) FICE y f) alta resolución. Cada patrón encontrado se grabó, se fotografió y se guardó en JPEG en programa Power Point. Los patólogos evaluaron la biopsia del patrón observado sin tener datos del paciente. Se incluyeron 30 pacientes: 11 hombres y 19 mujeres con rango de edad 20-83 años y promedio 51,73 años. Solo con magnificación sola o con cromoscopia virtual se observaron los patrones de mucosa. En el tipo 3 se diagnosticó esófago de Barrett en 33,33% y en ninguno de los otros. Conclusión: La magnificación endoscópica y cromoscopia virtual con FICE identifica metaplasia intestinal y diagnostica esófago de Barrett


Standard endoscopy does not identify Barrett's esophagus or mucosa patterns suggestive of intestinal metaplasia. Endoscopic magnification, vital and or virtual chromoscopy reduces this limitation. Aim: Identify intestinal metaplasia with endoscopic magnification and Flexible Spectral Imaging Colour Enhancement (FICE) corroborating it with histology. Patients: Individuals scheduled to undergo routine upper gastrointestinal endoscopy were enrolled. Upper gastrointestinal endoscopy was performed with Fujinon Inc. 590 EG ZW and EPX 4400 processor. Endoscopy was consecutively performed with: a) high resolution, b) FICE, c) high resolution, d) magnification, e) FICE, f) high resolution. Each found pattern was recorded, was photographed and was saved in JPEG in program Power Point. Biopsy was obtained of the predominant pattern and the pathologist assessed without patient information. Results: 30 patients were included, 11 men and 19 women with 20-83 years and 51.73 years average age range. Patterns of mucosa were observed only with magnification and virtual chromoscopy, Barrett's esophagus was diagnosed in 33.33% of type 3 and none in type 1 and 2. The endoscopic magnification and virtual chromoscopy with FICE identifies intestinal metaplasia and let diagnose Barrett's esophagus.

ABSTRACT

O câncer colorretal (CCR) é uma das maiores causas de óbito no mundo industrializado, com uma incidência anual de 800.000 casos novos, o que significa 8,5% de todos os novos e 12% das mortes relacionadas a essa doença. No Brasil, excluindo-se os cânceres de pele não melanoma, o CCR é o quarto mais freqüente entre os homens e o terceiro entre as mulheres. O risco de desenvolver CCR é de aproximadamente 5% a 6% na população ocidental. Existem evidências epidemiológicas de redução do CCR em 60% -90% quando a colonoscopia com polipectomia é usada preventivamente A colonoscopia ainda é o melhor método para o diagnóstico precoce do CCR e das lesões precursoras. Contudo existem falhas de detecção não desprezíveis. O objetivo deste estudo foi comparar o resultado do exame detalhado da mucosa do cólon e do reto através da colonoscopia convencional, da cromoendoscopia e do NBI, na detecção de lesões elevadas, deprimidas e planas em pacientes submetidos ao exame sem antecedentes pessoais e ou familiares. Entre janeiro de 2007 e outubro de 2009 foram selecionados 181 pacientes divididos aleatoriamente em três grupos: A: 48 pacientes, controle; B: 29 pacientes, NBI; C: 104 pacientes, cromoscopia difusa. Pode-se observar que dos 181 pacientes examinados 38 (21%) não apresentavam lesões. Os 143 pacientes com lesão, apresentaram um número médio de 2,65 lesões, com mínimo de 1 e máximo de 7 lesões. Nos total dos 181 pacientes e no conjunto dos 143 pacientes com lesões não foi observada diferença estatisticamente significante entre os três grupos A, B e C para a idade, o tempo reto-ceco e o tempo ceco-reto, enquanto que para a altura, peso e conseqüente IMC houve variação estatística. O tamanho médio das 379 lesões encontradas nos 143 pacientes, avaliado pelo seu diâmetro foi de 5,45 ± 2,84 mm, sem variação estatística entre os grupos, entre os hemicólons e entre os hemicólons nos grupos. Os tamanhos das lesões foram reunidos em três intervalos distintos: até 5 mm (76,30%)...


Colorectal cancer (CRC) is one of the largest causes of death on the industrialized world. Its annual incidence of 800.000 new cases means 8,5% of all the new ones and 12% of deaths related to this disease. In Brazil, excluding the non-melanoma skin-cancers, CRC is the fourth more frequent among men and the third one among women. The risk for developping CRC is approximately of 5 to 6% on the Western population. There are epidemiological evidences for reducing CRC on 60-90% when colonoscopy with polypectomy is used preventively. Colonoscopy is still the best method both for the early dyagnosis of CRC and precursor lesions. However, there are non-contemptible failures on the detection. This paper purpose was comparing the result of colon and rectum mucous membrane detailed test through conventional colonoscopy, chromoendoscopy and NBI, on the detection of augmented, depressed and flat lesions in patients submitted to it without any personal or familiar antecedents. Between January 2007 and October 2009 181 patients were selected randomically and divided into 3 groups: A: 48 control patients; B: 29 patients, NBI; C: 104 patients, diffuse chromoscopy. It is observed that, from the 181 examined patients, 38 (21%) didnt present lesions. The 143 patients with lesion, presented an average number of 2,65 lesions, with a minimum of 1 and a maximum of 7 lesions. On the total of the 181 patients and on the whole of the 143 patients with lesions it was not observed any statistically significant difference among the three groups A, B and C as for Age, the Rectum-Cecum Time and the Cecum-Rectum Time, while there was a statistical variation for Height, Weight and consequent bmi. The average size of the 379 lesions found on the 143 patients, assessed by its diameter was of 5,45 mm (2.14 in.) + 2,84 mm (1,11 in), without any statistical variation among the groups, among the hemicolons and among the hemicolons in the groups. The size of the lesions were gathered into three...

ABSTRACT

Este trabajo tiene como propósito la descripción de los focos de criptas aberrantes utilizando colonoscopio de alta resolución sin magnificación. Los focos de criptas aberrantes se observan como lesiones planas o ligeramente elevadas, con un diámetro entre 1-4 mm, pueden presentar depresión central y con endoscopia de alta resolución, aún sin magnificación es posible ver el patrón de criptas. Usualmente se encuentran en la cercanía de adenomas. Una vez visualizada la lesión se procedió a realizar cromoscopía previa irrigación con 3-5 cc de ácido acético al 0,5 % como agente mucolítico, luego de 30 segundos se irrigó la zona con el colorante: azul de metileno al 0,5% o índigo carmín 0,5-1 %. Se intentó clasificar las lesiones de acuerdo a los criterios establecidos en la literatura para tratar de establecer correlación con el diagnóstico histológico. Se incluyeron 40 pacientes, en 67,5 % de los casos los focos de criptas aberrantes fueron localizados en colon recto-sigmoides. Existió una correlación endoscópica e histológica entre los focos de criptas aberrantes displásica y alta asociación con pólipos.


In our study, we used standard high resolution colonoscope to describe aberrant crypt foci. Aberrant crypt foci are either flat or slightly elevated lesions with a 1 to 4 mm of diameter with central depression. Usually these foci have been close to adenomas. Once the lesion was identified, it was first irrigated with 0.5% of acetic acid to remove mucus from the surface. After 30 seconds it was irrigated again with 0.5 % methylene blue or 0.5 to 1% indigo carmine. We tried to classify the lesion based on the literature criteria and compare it with the histopathology diagnosis. 40 patients were evaluated in this study, 67, 5 % of the aberrant crypt foci were located in rectosigmoid colon. We found direct histopathologic and endoscopic correlation between dysplasic aberrant crypt foci and high association with polyps.
