Development and Validation of a Patient-Reported Experience Measure for Gastrointestinal Endoscopy: The Comprehensive Endoscopy Satisfaction Tool (CEST).

GOALS: We aimed to develop and validate a patient-reported experience measure for gastrointestinal (GI) endoscopy, the Comprehensive Endoscopy Satisfaction Tool that captures relevant domains that influence the patient's experience and identify factors that shape satisfaction. BACKGROUND: Patient-reported experience measures are used to capture specific quality aspects of health care services. GI endoscopic services are high-volume services, and there is a lack of specific, validated instruments to capture various domains that shape the patients' experience with routine clinical endoscopic services. STUDY: After an environmental scan and structured literature review, focus groups with patients were conducted to identify relevant factors influencing the patient experience with GI endoscopic services. After an initial validation in 101 patients undergoing routine GI endoscopies, the instrument was tested in 7800 patients. In addition, the influence of sociodemographic factors on global satisfaction was explored. RESULTS: The final version included 26 specific items plus 4 global ratings for preprocedure, experience on day of procedure, postprocedure care, and infrastructure. In addition, a global rating of the overall experience was included. Patient satisfaction was significantly higher in older patients (P<0.001) but not influenced by gender, nationality, marital status, education, or employment status. Interestingly, during periods of coronavirus disease-19-related service interruptions, the Net Promoter Score was significantly reduced (P<0.0001) providing evidence for the responsiveness of the instrument. CONCLUSIONS: The Comprehensive Endoscopy Satisfaction Tool is a valid measure for the patient experience with the various components of endoscopic services, allows for the identification of domains that impact on the patient experience and is a practical tool to compare patient satisfaction over time and across facilities.

Conducting research on diet-microbiome interactions: A review of current challenges, essential methodological principles, and recommendations for best practice in study design.

Diet is one of the strongest modulators of the gut microbiome. However, the complexity of the interactions between diet and the microbial community emphasises the need for a robust study design and continued methodological development. This review aims to summarise considerations for conducting high-quality diet-microbiome research, outline key challenges unique to the field, and provide advice for addressing these in a practical manner useful to dietitians, microbiologists, gastroenterologists and other diet-microbiome researchers. Searches of databases and references from relevant articles were conducted using the primary search terms 'diet', 'diet intervention', 'dietary analysis', 'microbiome' and 'microbiota', alone or in combination. Publications were considered relevant if they addressed methods for diet and/or microbiome research, or were a human study relevant to diet-microbiome interactions. Best-practice design in diet-microbiome research requires appropriate consideration of the study population and careful choice of trial design and data collection methodology. Ongoing challenges include the collection of dietary data that accurately reflects intake at a timescale relevant to microbial community structure and metabolism, measurement of nutrients in foods pertinent to microbes, improving ability to measure and understand microbial metabolic and functional properties, adequately powering studies, and the considered analysis of multivariate compositional datasets. Collaboration across the disciplines of nutrition science and microbiology is crucial for high-quality diet-microbiome research. Improvements in our understanding of the interaction between nutrient intake and microbial metabolism, as well as continued methodological innovation, will facilitate development of effective evidence-based personalised dietary treatments.

Induction of Meal-related Symptoms as a Novel Mechanism of Action of the Duodenal-Jejunal Bypass Sleeve.

BACKGROUND: Treatment with a duodenal-jejunal bypass sleeve (DJBS) induces clinically significant weight loss, but little is known about the mechanisms of action of this device. AIM: The aim of this study was to characterize the mechanisms of action of the DJBS and determine the durability of weight loss and metabolic improvements. MATERIALS AND METHODS: We studied a cohort of 19 subjects with severe obesity and type 2 diabetes (baseline body mass index: 43.7±5.3 kg/m). Anthropometry, body composition, blood pressure, biochemical measures, and dietary intake were monitored for 48 weeks after DJBS implantation, and then for 1 year after device removal. Gastric emptying and triglyceride absorption were measured at baseline, 8 weeks after implant, and within 3 weeks of device explant. Visceral sensory function was assessed at baseline, 4 weeks after implant, and within 3 weeks after explant. RESULTS: Significant weight loss (P<0.01) occurred following DJBS placement, with a mean weight reduction of 17.0±6.5% at 48 weeks. The symptom burden following a standardized nutrient challenge was increased after DJBS implantation (P<0.05), returning to baseline after DJBS removal. Neither gastric emptying nor triglyceride absorption changed with the device in situ. A significant reduction in energy intake was observed [baseline: 7703±2978 kJ (1841±712 kcal), 24 weeks: 4824±2259 kJ (1153±540 kcal), and 48 weeks: 4474±1468 kJ (1069±351 kcal)]. After 1 year, anthropometry remained significantly improved, but there was no durable impact on metabolic outcomes. CONCLUSIONS: DJBS treatment resulted in substantial weight loss. Weight loss is related to reduced caloric intake, which seems linked to an augmented upper gastrointestinal symptom response, but not altered fat absorption.

Structured oropharynx, hypopharynx and larynx assessment during routine esophagogastroduodenoscopy improves detection of pre- and early cancerous lesions: a multicenter, comparative study.

Background and study aims A structured assessment of the oropharynx, hypopharynx and larynx (OHL) may improve the diagnostic yield for the detection of precancerous and early cancerous lesions (PECLs) during routine esophagogastroduodenoscopy (EGD). Thus, we aimed to compare routine EGDs ± structured OHL assessment (SOHLA), including photo documentation with regard to the detection of PECLs. Patients and methods Consecutive patients with elective EGD were arbitrarily allocated to endoscopy lists with or without SOHLA. All detected OHL abnormalities were assessed by an otolaryngologist-head & neck surgeon (ORL-HNS) and the frequency of PECLS detected during SOHLA vs. standard cohort compared. Results Data from 1000 EGDs with and 1000 EGDs without SOHLA were analyzed. SOHLA was successful in 93.3 % of patients, with a median assessment time of 45 seconds (interquartile range: 40-50). SOHLA identified 46 potential PECLs, including two benign subepithelial lesions (4.6 %, 95 % CI: 3.4-6.1) while without SOHLA, no malignant and only one benign lesion was found ( P  < 0.05). ORL-HNS imaging review classified 23 lesions (2.3 %, 95 % CI: 1.5-3.4) as concerning and ORL-HNS clinic assessment was arranged. This identified six PECLs (0.6 %, 95 % CI: 0.2-1.3) including two pharyngeal squamous cell lesions (0.2 %) demonstrating high-grade dysplasia and carcinoma in situ (CIS) and four premalignant glottic lesions (0.4 %) demonstrating low-grade dysplasia and CIS. Conclusion In the routine setting of a gastrointestinal endoscopy practice precancerous and early cancerous lesions of the oropharynx, hypopharynx, and larynx are rare (< 1 %) but can be detected with a structured assessment of this region during routine upper gastrointestinal endoscopy.
