Abstract
Background and objectives

There are few scales with prospective validation for the assessment of the upper gastrointestinal mucosal cleanliness during an esophagogastroduodenoscopy (EGD). The aim of this study was to develop a valid and reproducible cleanliness scale for use during an EGD.

Methods

We developed a cleanliness scale (Barcelona scale) with a score (0–2 points) of five segments of the upper gastrointestinal tract with thorough cleaning techniques (esophagus, fundus, body, antrum, and duodenum). First, 125 photos (25 of each area) were assessed, and a score was assigned to each image by consensus among 7 experts endoscopists. Subsequently, 100 of the 125 images were selected and the inter- and intra-observer variability of 15 previously trained endoscopists was evaluated using the same images at two different times.

Results

In total, 1500 assessments were performed. In 1336/1500 observations (89%) there was agreement with the consensus score, with a mean kappa value of 0.83 (0.45–0.96). In the second evaluation, in 1330/1500 observations (89%) there was agreement with the consensus score, with a mean kappa value of 0.82 (0.45–0.93). The intra-observer variability was 0.89 (0.76–0.99).

Conclusions

The Barcelona cleanliness scale is a valid measure and reproducible with minimal training. Its application in clinical practice is a significant step to standardize the quality of the EGD.

Resumen
Introducción

Existen pocas escalas validadas prospectivamente para evaluar la limpieza de la mucosa esofagogastroduodenal durante la endoscopia digestiva alta (EDA). El objetivo de este estudio fue desarrollar una escala válida y reproducible para su uso en la realización de una EDA.

Métodos

Desarrollamos una escala de limpieza (escala Barcelona) en la que se aplicó una puntuación de 0 a 2 a cinco áreas del tracto digestivo superior (esófago, fundus, cuerpo, antro y duodeno) después de haber realizado todas las maniobras de lavado necesarias. Inicialmente, se evaluaron 125 fotos (25 de cada área) y se asignó una puntuación (de 0 a 2) a cada una por consenso entre siete endoscopistas. Posteriormente, se seleccionaron 100 de las 125 fotografías y se evaluó la variabilidad inter e intraobservador de 15 endoscopistas previamente formados utilizando las mismas imágenes en dos momentos diferentes.

Resultados

Se efectuaron un total de 1.500 observaciones. En 1.336/1.500 de ellas (89%) hubo coincidencia con la puntuación del consenso, siendo el valor medio de kappa de 0,83 (0,45-0,96). En la segunda evaluación, en 1.330/1.500 observaciones (89%) hubo coincidencia con la puntuación del consenso, siendo el valor medio de kappa de 0,82 (mínimo 0,45 y máximo 0,93). La variabilidad intraobservador fue de 0,89 (0,76-0,99).

Conclusiones

La escala de limpieza Barcelona es una medida válida y reproducible con un mínimo entrenamiento. Su uso en la práctica clínica podría ser un paso significativo para estandarizar la calidad de la EDA.
