Background:Some validated scales for assessing upper gastrointestinal (UGI) cleanliness have been developed, though none have been widely implemented. Objectives:To evaluate the association between the presence of clinically significant lesions (CSLs) in the UGI tract and mucosal cleanliness using the Barcelona Scale. The secondary objective includes assessing the safety of water lavage during esophagogastroduodenoscopy (EGD). Design:Multicenter prospective study conducted in 14 hospitals in Spain. Methods:From January 2022 to December 2023, patients undergoing EGD were included. After cleansing, the esophagus, fundus, corpus, antrum, and duodenum were scored from 0 (unassessable due to content) to 2 (fully visualized mucosa), with a maximum score of 10. Results:A total of 641 patients were included, and 3205 segments were assessed: 2594 scored "2," 604 "1," and 7 "0." In 272 patients, 327 CSLs were identified: 93 (14.5%) in the esophagus, 223 (34.8%) in the stomach, and 11 (1.7%) in the duodenum. Only five cases of neoplasia were found, all in segments scored "2" (global score ⩾ 9). The CSL detection rates were 0%, 5.3%, and 11.4% for scores 0, 1, and 2, respectively (p < 0.001), with a significantly higher rate for score "2" compared to "1" (OR 2.29, 95% CI 1.57-3.34). Besides the degree of cleanliness, several factors were independently associated with CSL detection, including the use of a high-definition endoscope (OR 1.87, 95% CI 1.14-3.23), male sex (OR 1.54, 95% CI 1.1-2.17), and age ⩾58 years (OR 1.54, 95% CI 1.09-2.17). Conclusion:The Barcelona scale may be a valid instrument for assessing the quality of cleanliness during EGD in real clinical practice, as it improves the detection of CSL in the UGI.

Aims To evaluate the effectiveness and safety of endoscopic vacuum therapy (EVT) for the treatment of upper gastrointestinal (GI) defects. To assess risk factors associated with EVT failure and in-hospital mortality in these patients.

Aims Recommendations for improving the quality of colonoscopy include collecting data on patient experience with validated questionnaires. The Colonoscopy Satisfaction and Safety Questionnaire based on Patient experience (CSSQP) was recently developed and validated within the Spanish Bowel Cancer Screening Program. The present multicenter study aimed to apply the CSSQP to identify factors related to patient experiences, including all the indication for colonoscopy.

Aims National Spanish societies (AEG-SEED) proposed priorization criteria for restarting the endoscopic activity after the first wave of COVID19 pandemic. The aim was to evaluate the diagnostic yield of esophagogastroduodenoscopies(EGD) and colonoscopies in symptomatic patients for detecting clinically relevant lesions(CRL)

Adenoma detection rate (ADR) is the most important quality measure in screening colonoscopies because it's inversely related to the development of interval cancer and mortality. Minimum standard ADR recommended according to ESGE Guidelines is ≥25%; however, this recommendation's made for primary screening colonoscopies and it remains unknown whether this cut-off must be the same for other colonoscopy indications. Hence, the aim of this study was to describe the ADR based on procedure indication and to predict the ADR recommended for other indications.

Colorectal cancer (CRC) screening aims the reduction of the incidence and mortality of CRC, and fecal immunochemical test (FIT) is one of the main screenings methods. Since it was introduced, the number of colonoscopies has increased, so the burden of procedures as well. False-positive FIT results (FP-FIT) increase the unnecessary procedures and there is scarce evidence about the FP-FIT rate in Spain. So the aim of this study was to evaluate the FP-FIT rate and the factors related to it.

Colonoscopy plays a key role in prevention and diagnosis of colorectal cancer (CRC), and it's quality influences the amount of interval cancer. However, we have little information on quality compliance standards in Spain. The aim was to evaluate the fulfilment of colonoscopy quality indicators in a sample of centres in Spain.

La Resección Endoscópica Mucosa (REM) de pólipos colorrectales sésiles se asocia a una recurrencia de alrededor del 25%. No existe evidencia si NBI respecto Luz blanca (LB) pueda mejorar la detección de tejido residual en el seguimiento de estas lesiones.

La detección de pólipos serrados (PS) es difícil debido a su morfología y apariencia. Una correcta identificación conduciría al diagnóstico de un síndrome de poliposis serrada (SPS), entidad que requiere un seguimiento muy estrecho por el mayor riesgo de cáncer colorrectal.

La clínica obstructiva en el cáncer colorrectal (CCR) en estadio paliativo obliga a un tratamiento sintomático. La prótesis de colon (PC) es actualmente el tratamiento de elección si bien es un tema en discusión que la cirugía resectiva (CR) pueda aumentar la supervivencia en éstos pacientes.

Introducción: Estudios previos demuestran que los pacientes diabéticos responden peor a las preparaciones habituales. Un protocolo específico de preparación para pacientes diabéticos puede mejorar la limpieza y aceptabilidad.

Introducción: Las guías internacionales recomiendan la colonoscopia de rutina tras un episodio de diverticulitis aguda (DA) para descartar la presencia de neoplasia avanzada de colon (NAC). Sin embargo, tras la incorporación de la tomografía computarizada (TC) en el algoritmo diagnóstico, dicha recomendación está en entredicho.

Introducción: La diabetes mellitus se ha asociado con un riesgo superior de desarrollo de cáncer colorrectal (CCR) aunque los resultados son discordantes. Un estudio reciente con población asiática ha sugerido que los adenomas se desarrollan en edades más tempranas en pacientes diabéticos.

Collecting the evidence about the quality of colonoscopy screening for colorectal cancer (CRC) in order to serve as a tool for screening programs, endoscopy units and endoscopists that perform screening colonoscopies. Defining and establishing quality indicators and minimum requirements based on available evidence that endoscopy units and endoscopists involved in CRC screening programs should meet. Providing evidence about procedures that may improve the quality of colonoscopy.

La tasa de detección de adenomas (TDA) es el más importante indicador de calidad en la colonoscopia de cribado y se encuentra directamente relacionado con la aparición del cáncer de intervalo. La tasa de detección de pólipos (TDP) tiene una buena correlación con la TDA y puede ser también utilizada como indicador de calidad. Diversos factores pueden influir sobre la TDP y su importancia relativa aun está bajo discusión. El objetivo principal de este estudio es detectar factores que pueden influir la TDP en la colonoscopia de cribado.

Introducción: La incidencia del cáncer de esófago está aumentando en los últimos años. La mayoría de los casos tienen una enfermedad no resecable cuando se diagnostican y la supervivencia general a los 5 años es desoladora (<20%). La colocación de una prótesis esofágica autoexpandible (PEA), asociada o no a quimioterapia o radioterapia, es la practica clínica habitual para solucionar la disfagia maligna. Existen múltiples tipos de prótesis y no hay un consenso en su uso. Existe escasa información sobre la durabilidad de las prótesis y sus complicaciones tardías.
