ABSTRACT

La mayoría de pacientes con enfermedad de reflujo gastroesofágico no tienen lesiones erosivas en esófago. Los cambios mínimos esofágicos que incluyen alteraciones blancas, rojizas, edematosas y/o acantósicas usualmente no percibidos durante la endoscopia se incluyen en Japón como parte de la enfermedad de reflujo no erosiva. Previo consentimiento se incluyeron a los individuos con síntomas de reflujo gastroesofágico y se compararon con un grupo sin éstos. Se utilizó equipo Fujinon HR250. La endoscopia se grabó en DVD y de rutina se fotografió la unión Esófago Gástrica y la Escamo Columnar. Se empleó la clasificación de Los Ángeles modificada por los japoneses que incluye Cambios Mínimos Esofágicos. Se practicó endoscopia digestiva superior en 146 pacientes 86 hombres y 60 mujeres con rango de edad 15-83 años y promedio 38,71 años. Se diferenciaron tres grupos: I) Sin cambios esofágicos, II) Con cambios esofágicos erosivos y III) Con cambios mínimos esofágicos. Los Cambios Mínimos Esofágicos se pudieron haber reportado en 53,44% y en 36,66% de pacientes con y sin síntomas de reflujo gastroesofágico respectivamente. Los Cambios Mínimos Esofágicos son frecuentes y pasan desapercibidos si no sabemos que investigar y no insistimos en buscarlos en pacientes con Enfermedad de Reflujo No Erosiva...


Most patients diagnosed with gastroesophageal reflux disease do not show erosive lesions in the esophagus. The esophagus minimal changes, which include white, reddish, edematous and/or acanthotic disturbances, are usually not perceived during endoscopic procedure and in Japan are included as part of the non erosive reflux disease. With prior consent, subjects with symptoms of gastroesophageal reflux were included, and were compared with a group without said symptoms. Fujinon HR250 equipment was used. The endoscopy was recorded on DVD and, routinely, photographs of the gastroesophageal and the squamous columnar junctions were taken. Los Angeles classification was used, as modified by the Japanese which includes Esophagus Minimal Changes. Upper digestive endoscopy was used in 146 patients: 86 men and 60 women, with ages ranging between 15 and 83, and an average of 38.71. Three groups were distinguished: I) Without changes in the esophagus; II) With erosive changes in the esophagus; and III) With esophagus minimal changes. Esophagus Minimal Changes might be reported in 53.44% and in 36.66% of patients with and without gastroesophageal reflux symptoms, respectively. Esophagus Minimal Changes are frequent but are unobserved if researcher does not know what the investigation must be on and if researcher does not insist in looking for them in patients with a diagnosis of Non Erosive Reflux Disease...

ABSTRACT

El Acido Acético produce desnaturalización intracelular reversible de las proteínas citoplasmáticas. Al ser rociado en Esófago distal a nivel de la Unión Escamo Columnar permite con el video endoscopio de alta resolución, la detección de áreas no visibles de Epitelio Columnar y resalta la unión Escamo Columnar. Previo consentimiento se incluyeron a los individuos que tenían indicación de endoscopia digestiva superior. El procedimiento endoscópico se realizó con equipo Fujinon HR250. Se instiló a través del canal de biopsia, con catéter de polietileno, los 5cm distales del tercio inferior del esófago, 5cc-10cc de Acido Acético al 5%, seguido de lavado con 20cc de agua a temperatura ambiente. En todos los casos se observó blanquecimiento de la zona irrigada con Acido Acético. Casi inmediatamente se identificó la demarcación de la Unión Escamo Columnar. La porción gástrica proximal y el Epitelio Columnar en Esófago se enrojecieron al lavar con agua permitiendo observar el Patrón Pit resaltado y magnificado. No hubo efectos adversos durante ni después del procedimiento. El Acido Acético es un método fácil, rápido, seguro y barato que en Esófago resalta la Unión Escamo Columnar, aumenta la detección e identificación de Epitelio Columnar y de su Patrón Pit...


Acetic Acid produces reversible intracellular denaturalization of cytoplasmic proteins. When sprayed at distal esophagus, at squamous columnar junction, by using a high-resolution endoscopy video, it allows the detection of non-visible areas of the columnar epithelium and highlights the squamous columnar junction. After letting them know, subjects who had been prescribed an upper digestive endoscopy were included. The equipment used to perform the endoscopic procedure was Fujinon HR250. 5-10cc 5% acetic acid was instilled with a polyethylene catheter through the biopsia channel in the distal 5cm of the esophagus further washed away by water at room temperature. Whitening of the acetic-acid-irrigated zone was observed in all cases. Almost immediately the squamous columnar junction demarcation was identified. The proximal gastric portion and the esophagus columnar epithelium were reddened with the water washing, allowing a highlighted and enhanced pit pattern to be observed. No adverse effects showed during or after the procedure. Acetic acid is an easy, rapid, safe, and inexpensive that, in the esophagus, highlights the squamous columnar junction, improves the detection and identification of the columnar epithelium and of its pit pattern as well...
