Applicability of the Barcelona scale to assess the quality of cleanliness of mucosa at esophagogastroduodenoscopy / Aplicabilidad de la escala Barcelona para valorar la calidad de la limpieza de la mucosa en la esofagogastroduodenoscopia

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. (AU)

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. (AU)

Performance of a Shotgun Prediction Model for Colorectal Cancer When Using 16S rRNA Sequencing Data.

Colorectal cancer (CRC), the third most common cancer globally, has shown links to disturbed gut microbiota. While significant efforts have been made to establish a microbial signature indicative of CRC using shotgun metagenomic sequencing, the challenge lies in validating this signature with 16S ribosomal RNA (16S) gene sequencing. The primary obstacle is reconciling the differing outputs of these two methodologies, which often lead to divergent statistical models and conclusions. In this study, we introduce an algorithm designed to bridge this gap by mapping shotgun-derived taxa to their 16S counterparts. This mapping enables us to assess the predictive performance of a shotgun-based microbiome signature using 16S data. Our results demonstrate a reduction in performance when applying the 16S-mapped taxa in the shotgun prediction model, though it retains statistical significance. This suggests that while an exact match between shotgun and 16S data may not yet be feasible, our approach provides a viable method for comparative analysis and validation in the context of CRC-associated microbiome research.

In vivo computer-aided diagnosis of colorectal polyps using white light endoscopy.

Background and study aims Artificial intelligence is currently able to accurately predict the histology of colorectal polyps. However, systems developed to date use complex optical technologies and have not been tested in vivo. The objective of this study was to evaluate the efficacy of a new deep learning-based optical diagnosis system, ATENEA, in a real clinical setting using only high-definition white light endoscopy (WLE) and to compare its performance with endoscopists. Methods ATENEA was prospectively tested in real life on consecutive polyps detected in colorectal cancer screening colonoscopies at Hospital Clínic. No images were discarded, and only WLE was used. The in vivo ATENEA's prediction (adenoma vs non-adenoma) was compared with the prediction of four staff endoscopists without specific training in optical diagnosis for the study purposes. Endoscopists were blind to the ATENEA output. Histology was the gold standard. Results Ninety polyps (median size: 5 mm, range: 2-25) from 31 patients were included of which 69 (76.7 %) were adenomas. ATENEA correctly predicted the histology in 63 of 69 (91.3 %, 95 % CI: 82 %-97 %) adenomas and 12 of 21 (57.1 %, 95 % CI: 34 %-78 %) non-adenomas while endoscopists made correct predictions in 52 of 69 (75.4 %, 95 % CI: 60 %-85 %) and 20 of 21 (95.2 %, 95 % CI: 76 %-100 %), respectively. The global accuracy was 83.3 % (95 % CI: 74%-90 %) and 80 % (95 % CI: 70 %-88 %) for ATENEA and endoscopists, respectively. Conclusion ATENEA can accurately be used for in vivo characterization of colorectal polyps, enabling the endoscopist to make direct decisions. ATENEA showed a global accuracy similar to that of endoscopists despite an unsatisfactory performance for non-adenomatous lesions.

Meta-Analysis and Validation of a Colorectal Cancer Risk Prediction Model Using Deep Sequenced Fecal Metagenomes.

The gut microbiome is a potential modifiable risk factor for colorectal cancer (CRC). We re-analyzed all eight previously published stool sequencing data and conducted an MWAS meta-analysis. We used cross-validated LASSO predictive models to identify a microbiome signature for predicting the risk of CRC and precancerous lesions. These models were validated in a new study, Colorectal Cancer Screening (COLSCREEN), including 156 participants that were recruited in a CRC screening context. The MWAS meta-analysis identified 95 bacterial species that were statistically significantly associated with CRC (FDR < 0.05). The LASSO CRC predictive model obtained an area under the receiver operating characteristic curve (aROC) of 0.81 (95%CI: 0.78−0.83) and the validation in the COLSCREEN dataset was 0.75 (95%CI: 0.66−0.84). This model selected a total of 32 species. The aROC of this CRC-trained model to predict precancerous lesions was 0.52 (95%CI: 0.41−0.63). We have identified a signature of 32 bacterial species that have a good predictive accuracy to identify CRC but not precancerous lesions, suggesting that the identified microbes that were enriched or depleted in CRC are merely a consequence of the tumor. Further studies should focus on CRC as well as precancerous lesions with the intent to implement a microbiome signature in CRC screening programs.

Prevalence of missed lesions in patients with inadequate bowel preparation through a very early repeat colonoscopy.

OBJECTIVES: When bowel preparation (BP) is inadequate, international guidelines recommend repeating the colonoscopy within 1 year to avoid missing clinically relevant lesions. We aimed to determine the rate of missed lesions in patients with inadequate BP through a very early repeat colonoscopy with adequate BP. METHODS: Post hoc analysis was conducted using data collected from a prospective multicenter randomized clinical trial including patients with inadequate BP and then repeat colonoscopy. Inadequate BP was defined as the Boston Bowel Preparation Scale (BBPS) score <2 points in any segment. We included patients with any indication for colonoscopy. The adenoma detection rate (ADR), advanced ADR (AADR), and serrated polyp detection rate (SPDR) were calculated for index and repeat colonoscopies. RESULTS: Of the 651 patients with inadequate BP from the original trial, 413 (63.4%) achieved adequate BP on repeat colonoscopy. The median interval between index and repeat colonoscopies was 28 days. On repeat colonoscopy, the ADR was 45.3% (95% confidence interval [CI] 40.5-50.1%), the AADR was 10.9% (95% CI 8.1-14.3%), and the SPDR was 14.3% (95% CI 10.9-17.7%). Cancer was discovered in four patients (1%; 95% CI 0.2-2.5%). A total of 60.2% of all advanced adenoma (AA) were discovered on repeat colonoscopy. A colon segment scored BBPS = 0 had most AA (66.1%) and all four cancers. CONCLUSION: Patients with inadequate BP present a high rate of AAs on repeat colonoscopy. When a colonoscopy has a colon segment score BBPS = 0, we recommend repeating the colonoscopy as soon as possible.

Síndrome auriculotemporal tardío en el adulto: síndrome de Frey / Late auriculotemporal syndrome in adult: Frey syndrome

Objetivos: reconocimiento de una patología muy poco prevalente en Atención Primaria que cursa con sensación de humedad en la cara. Metodología: se expone un caso en el que tras la anamnesis se plantea la realización de la prueba de Minor para dilucidar tanto la zona afectada como su naturaleza. Conclusiones: ante las secreciones faciales de origen y composición desconocida, se puede sospechar patología posquirúrgica de la parótida, aun habiendo pasado mucho tiempo y que pudieran requerir o no tratamiento para su solución. También puede orientar tanto en preferencia como destino en el diagnóstico diferencial con fístulas salivales o de líquido cefalorraquídeo.(AU)

Objectives: recognition of a very rare pathology in primary care whose clinical course includes a feeling of moisture on the face. Methodology: a case is reported in which after history the Minor test was proposed to elucidate both the affected area and its nature. Conclusions: when clinicians differentiate between facial secretions of unknown origin and composition, post-surgical pathology of the parotid may be suspected, even after a long time. This may or not require treatment for its resolution. It can also provide guidance both in terms of preference and final differential diagnosis with salivary fistulas or cerebrospinal fluid.(AU)

Endoscopy-Related Bleeding and Thromboembolic Events in Patients on Direct Oral Anticoagulants or Vitamin K Antagonists.

BACKGROUND & AIMS: Few prospective studies have assessed the safety of direct oral anticoagulants (DOACs) in elective endoscopy. Our primary aim was to compare the risks of endoscopy-related gastrointestinal bleeding and thromboembolic events in patients on DOACs or vitamin K antagonists (VKAs) in this setting. Secondarily, we examined the impact of the timing of anticoagulant resumption on the risk of delayed bleeding in high-risk therapeutic procedures. METHODS: We conducted a multicenter, prospective, observational study from January 2018 to March 2020 of 1602 patients on oral anticoagulants (1004 on VKAs and 598 on DOACs) undergoing 1874 elective endoscopic procedures. Our primary outcomes were 90-day thromboembolic events and 30-day endoscopy-related gastrointestinal bleeding. The inverse probability of treatment weighting propensity score method was used for baseline covariate adjustment. RESULTS: The 2 groups had similar risks of endoscopy-related gastrointestinal bleeding (VKAs vs DOACs, 6.2% vs 6.7%; adjusted odds ratio [OR], 1.05; 95% CI, 0.67-1.65) and thromboembolic events (VKAs vs DOACs, 1.3% vs 1.5%; adjusted OR, 0.90; 95% CI, 0.34-2.38). In high bleeding risk procedures (n = 747), delayed anticoagulant resumption (> 48 hours or 24-48 hours vs < 24 hours) did not reduce the risk of postprocedural bleeding (10.3%, 9%, and 5.8%, respectively; adjusted P = .43). Hot and cold snare polypectomy were the most frequent high-risk interventions (41.8% and 39.8%, respectively). CONCLUSION: In a prospective study of patients on DOACs or VKAs undergoing elective endoscopy, endoscopy-related bleeding and thromboembolic events showed similar risk. Our study suggests that early anticoagulant resumption is safe in most patients, but more data are needed for advanced high-risk therapeutic procedures.

Diagnosis of Helicobacter pylori Infection by the Arrangement of Collecting Venules Using White Light Endoscopy: Evaluation of Interobserver Agreement.

BACKGROUND: Regular arrangement of collecting venules (RAC) in gastric mucosa accurately identifies patients without Helicobacter pylori (H pylori) infection. The aim of our study was to evaluate the reproducibility of RAC using white light endoscopy without magnification, in a European country, and to assess the impact of proton pump inhibitors (PPIs). METHODS: A multicenter prospective study with image capture of the distal lesser gastric curvature and gastric biopsies was performed. The presence of starfish-like minute points regularly distributed throughout lesser curvature was considered as RAC positive (RAC+). A set of 20 images was used for the training phase and inter and intra-observer agreements were calculated. RESULTS: 174 patients were included and 85 (48.9%) were taking PPIs. Kappa values for interobserver and intra-observer agreements were substantial (0.786) and excellent (0.906), respectively. H. pylori infection was diagnosed in 29 patients (16.7%): 10/85 with PPIs and 19/89 without PPIs (11.8% vs. 21.3%; p = 0.09). All RAC + patients were free of H. pylori infection, with a sensitivity and negative predictive value of 100%, regardless of PPI intake. CONCLUSION: The endoscopic diagnosis of H. pylori by RAC is an easy-to-learn and highly reproducible technique, even with PPI intake. Our results warrant RAC as a real-time diagnostic method for H. pylori-negative infection in Western practice.

Polygenic risk score across distinct colorectal cancer screening outcomes: from premalignant polyps to colorectal cancer.

BACKGROUND: Different risk-based colorectal cancer (CRC) screening strategies, such as the use of polygenic risk scores (PRS), have been evaluated to improve effectiveness of these programs. However, few studies have previously assessed its usefulness in a fecal immunochemical test (FIT)-based screening study. METHODS: A PRS of 133 single nucleotide polymorphisms was assessed for 3619 participants: population controls, screening controls, low-risk lesions (LRL), intermediate-risk (IRL), high-risk (HRL), CRC screening program cases, and clinically diagnosed CRC cases. The PRS was compared between the subset of cases (n = 648; IRL+HRL+CRC) and controls (n = 956; controls+LRL) recruited within a FIT-based screening program. Positive predictive values (PPV), negative predictive values (NPV), and the area under the receiver operating characteristic curve (aROC) were estimated using cross-validation. RESULTS: The overall PRS range was 110-156. PRS values increased along the CRC tumorigenesis pathway (Mann-Kendall P value 0.007). Within the screening subset, the PRS ranged 110-151 and was associated with higher risk-lesions and CRC risk (ORD10vsD1 1.92, 95% CI 1.22-3.03). The cross-validated aROC of the PRS for cases and controls was 0.56 (95% CI 0.53-0.59). Discrimination was equal when restricted to positive FIT (aROC 0.56), but lower among negative FIT (aROC 0.55). The overall PPV among positive FIT was 0.48. PPV were dependent on the number of risk alleles for positive FIT (PPVp10-p90 0.48-0.57). CONCLUSIONS: PRS plays an important role along the CRC tumorigenesis pathway; however, in practice, its utility to stratify the general population or as a second test after a FIT positive result is still doubtful. Currently, PRS is not able to safely stratify the general population since the improvement on PPV values is scarce.

Evaluación del cumplimiento a largo plazo de los indicadores de calidad en la esofagogastroduodenoscopia / Evaluation of long-term adherence to oesophagogastroduodenoscopy quality indicators

INTRODUCCIÓN: En un estudio previo demostramos que un pequeño programa de formación mejoraba los indicadores de calidad de la esofagogastroduodenoscopia (EGD) que llegaban a los estándares recomendados. Sin embargo, desconocemos el efecto de esta formación a largo plazo. El objetivo de este estudio fue valorar la calidad de las EGD después de 3años de haber realizado un programa de mejora. MATERIAL Y MÉTODOS: Estudio comparativo de 2 cohortes: EGD posteriores a un programa de formación realizado en 2016 (grupo A) y EGD en enero-marzo de 2019 (grupo B). El grupo B se dividió en 2 subgrupos: endoscopistas que habían participado en el programa de formación previo (B1) y los que no (B2). Se utilizaron los indicadores de calidad intraprocedimiento recomendados por la ASGE-ACG. RESULTADOS: Se analizaron un total de 1.236 EGD, 600 en el grupo A y 636 en el B (439 subgrupo B1 y 197 subgrupo B2). El número de exploraciones completas fue inferior en el grupo B (566 [94,3%] vs. 551 [86,6%]; p < 0,001). Se observó una disminución significativa en prácticamente todos los indicadores de calidad que, además, no alcanzaron los estándares recomendados: retroversión gástrica (96% vs. 81%; p < 0,001); protocolo de biopsias de Seattle (86% vs. 50%; p = 0,03), descripción de la lesión en la hemorragia (100% vs. 62%; p < 0,01), toma de ≥4 biopsias en sospecha de celiaquía (92,5% vs. 18%; p < 0,001), fotodocumentación de lesión (94% vs. 90%; p < 0,05). Cuando consideramos el global de la prueba (incluyendo la actuación correcta y la fotodocumentación adecuada), también se observó una disminución significativa (90,5% vs. 62%; p < 0,001). No hubo diferencias entre los subgrupos B1 y B2. CONCLUSIONES: La mejora observada en 2016 tras un programa de formación no perdura a los 3años. Es necesario hacer programas de formación continuados para mantener la calidad de la EGD por encima de los estándares recomendados

INTRODUCTION: In a previous study we demonstrated that a simple training programme improved quality indicators of Oesophagogastroduodenoscopy (OGD) achieving the recommended benchmarks. However, the long-term effect of this intervention is unknown. The aim of this study was to assess the quality of OGDs performed 3 years after of having completed a training programme. MATERIAL AND METHODS: A comparative study of 2 cohorts was designed as follows: Group A included OGDs performed in 2016 promptly after a training programme and Group B with OGDs performed from January to March 2019, this group was also divided into 2 subgroups: subgroup B1 of Endoscopists who had participated in the previous training programme and subgroup B2 of Endoscopists who had not. The intra-procedure quality indicators proposed by ASGE-ACG were used. RESULTS: A total of 1236 OGDs were analysed, 600 from Group A and 636 from Group B (439 subgroup B1 and 197 subgroup B2). The number of complete examinations was lower in Group B (566 [94.3%] vs. 551 [86.6%]; p < 0.001). A significant decrease was observed in nearly all quality indicators and they did not reach the recommended benchmarks: retroflexion in the stomach (96% vs. 81%; p < 0.001); Seattle biopsy protocol (86% vs. 50%; p = 0.03), description of the upper GI bleeding lesion (100% vs. 62%; p < 0.01), sufficient intestinal biopsy specimens (at least 4) in suspected coeliac disease (92.5% vs. 18%; p < 0.001), photo documentation of the lesion (94% vs. 90%; p < 0.05). Regarding the overall assessment of the procedure (including correct performance and adequate photo documentation), a significant decrease was also observed (90.5% vs. 62%; p < 0.001). There were no differences between subgroups B1 and B2. CONCLUSIONS: The improvement observed in 2016 after a training programme did not prevail after 3 years. In order to keep the quality of OGDs above the recommended benchmarks, it is necessary to implement continuous training programmes

Educational nurse-led telephone intervention shortly before colonoscopy as a salvage strategy after previous bowel preparation failure: a multicenter randomized trial.

BACKGROUND: The most important predictor of unsuccessful bowel preparation is previous failure. For those patients with previous failure, we hypothesized that a nurse-led educational intervention by telephone shortly before the colonoscopy appointment could improve cleansing efficacy. METHODS: We performed a multicenter, endoscopist-blinded, randomized controlled trial. Consecutive outpatients with previous inadequate bowel preparation were enrolled. Both groups received the same standard bowel preparation protocol. The intervention group also received reinforced education by telephone within 48 hours before the colonoscopy. The primary outcome was effective bowel preparation according to the Boston Bowel Preparation Scale. Intention-to-treat (ITT) analysis included all randomized patients. Per-protocol analysis included patients who could be contacted by telephone and the control cases. RESULTS: 657 participants were recruited by 11 Spanish hospitals. In the ITT analysis, there was no significant difference between the intervention and control groups in the rate of successful bowel preparation (77.3 % vs. 72 %; P = 0.12). In the intervention group, 267 patients (82.9 %) were contacted by telephone. Per-protocol analysis revealed significantly improved bowel preparation in the intervention group (83.5 % vs. 72.0 %; P = 0.001). CONCLUSION: Among all patients with previous inadequate bowel preparation, nurse-led telephone education did not result in a significant improvement in bowel cleansing. However, in the 83 % of patients who could be contacted, bowel preparation was substantially improved. Phone education may therefore be a useful tool for improving the quality of bowel preparation in those cases.
