RESUMO
Background and study aims The costs of reusable endoscope reprocessing have been evaluated, yet external validity of the findings remains challenging. The aim of this study was to assess the costs of purchase, maintenance, microbiological control, and reprocessing of a reusable duodenoscope per endoscopic retrograde cholangiopancreatography (ERCP) in France. Study findings exclude the costs of infection, downtime due to breakdown, reprocessing single-use material disposal, and device disposal, all of which should also be considered. Materials and methods The study encompassed both observational and theoretical approaches. Observational data were collected in four hospitals, from December 2019 to December 2020, with an ad hoc survey, based on 2016 and 2018 national guidelines for duodenoscope reprocessing. Costs were modeled, using the same guidelines, assuming a mean workload of 223 ERCP/duodenoscope/year. Results The mean observed cost of purchase, maintenance, microbiological control, reprocessing (human resources and consumables), and overhead (additional 35%) with a reusable duodenoscope was 80.23 (standard deviation 3.77) per ERCP. The corresponding mean theoretical cost was 182.71 for manual reprocessing without endoscope drying cabinet (EDC), 191.36 for manual reprocessing with EDC, 235.25 for automated endoscope reprocessing (AER) without EDC, and 253.62 for AER with EDC. Conclusions Because procedures, equipment, volume activity, number of duodenoscopes, human resources, and internal work organizations are hospital-dependent, observed costs varied between hospitals. Theoretical costs were higher than observed costs, showing that the theoretical approach is not sufficient. Hypotheses to explain the difference between the two approaches include failing to measure some costs in the survey and challenges in guideline implementation.
RESUMO
We are currently living in the throes of the COVID-19 pandemic that imposes a significant stress on health care providers and facilities. Europe is severely affected with an exponential increase in incident infections and deaths. The clinical manifestations of COVID-19 can be subtle, encompassing a broad spectrum from asymptomatic mild disease to severe respiratory illness. Health care professionals in endoscopy units are at increased risk of infection from COVID-19.âInfection prevention and control has been shown to be dramatically effective in assuring the safety of both health care professionals and patients. The European Society of Gastrointestinal Endoscopy (www.esge.com) and the European Society of Gastroenterology and Endoscopy Nurses and Associates (www.esgena.org) are joining forces to provide guidance during this pandemic to help assure the highest level of endoscopy care and protection against COVID-19 for both patients and endoscopy unit personnel. This guidance is based upon the best available evidence regarding assessment of risk during the current status of the pandemic and a consensus on which procedures to perform and the priorities on resumption. We appreciate the gaps in knowledge and evidence, especially on the proper strategy(ies) for the resumption of normal endoscopy practice during the upcoming phases and end of the pandemic and therefore a list of potential research questions is presented. New evidence may result in an updated statement.

BACKGROUND: We evaluated first the feasibility of endoscopic small-bowel polypectomy and second, the economic aspects, by comparing the cost of endoscopic and surgical polyp resection. METHODS: A prospective, observational, multicenter study included 494 patients with positive capsule endoscopy (CE) before double-balloon enteroscopy (DBE). We selected only CE with at least one polyp. The retrospective economic evaluation compared patients treated by DBE or surgery for small-bowel polypectomy. Hospital readmission because of repeat polyp resection or complication-related interventions was noted. The 1-year cost was estimated from the viewpoint of the healthcare system and included procedures, hospital admissions and follow up. RESULTS: CE indicated one or more polyps in 62 (12.5%) patients (32 males, 49 ± 5 years), all of whom underwent a successful DBE exploration. The DBE polyp diagnostic yield was 58%. There were no major complications. A total of 26 (42%) patients in the DBE group and 19 (39%) in the control group required hospital readmission. All readmissions in the DBE group were for repeat procedures to remove all polyps, and in the control group, for surgical complications. The total cost of the initial hospitalization (4014 ± 2239 DBE versus 11,620 ± 7183 surgery, p < 0.0001) and the 1-year total cost (8438 ± 9227 DBE versus 13,402 ± 7919 surgery, p < 0.0001) were lower in the DBE group. CONCLUSIONS: Endoscopic polypectomy was efficient and safe. The total cost at 1 year was less for endoscopy than surgery. DBE should be proposed as the first-line treatment for small-bowel polyp resection.
RESUMO
BACKGROUND & AIMS: Almost all colorectal polyps ≤ 5 mm are benign, yet current practice requires costly pathologic analysis. We aimed to develop and evaluate the validity of a simple narrow-band imaging (NBI)-based classification system for differentiating hyperplastic from adenomatous polyps. METHODS: The study was conducted in 4 phases: (1) evaluation of accuracy and reliability of histologic prediction by NBI-experienced colonoscopists; (2) development of a classification based on color, vessels, and surface pattern criteria, using a modified Delphi method; (3) validation of the component criteria by people not experienced in endoscopy or NBI analysis (25 medical students, 19 gastroenterology fellows) using 118 high-definition colorectal polyp images of known histology; and (4) validation of the classification system by NBI-trained gastroenterology fellows, using still images. We performed a pilot evaluation during real-time colonoscopy. RESULTS: We developed a classification system for the endoscopic diagnosis of colorectal polyp histology and established its predictive validity. When all 3 criteria were used, the specificity ranged from 94.9% to 100% and the combined sensitivity ranged from 8.5% to 61.0%. The specificities of the individual criteria were lower although the sensitivities were higher. During real-time colonoscopy, endoscopists made diagnoses with high confidence for 75% of consecutive small colorectal polyps, with 89% accuracy, 98% sensitivity, and 95% negative predictive values. CONCLUSIONS: We developed and established the validity of an NBI classification system that can be used to diagnose colorectal polyps. In preliminary real-time evaluation, the system allowed endoscopic diagnoses of colorectal polyp histology.

Small caliber endoscopes are one of the best examples of fantastic technological advancements in gastrointestinal endoscopy. First designed for pediatric patients in the 1970s, current small caliber videoendoscopes were used for unsedated transnasal gastrointestinal endoscopy after 1994. Nowadays, unsedated endoscopy can be successfully done using small caliber endoscopes via transoral or transnasal route in nearly 90% of cases. Several large studies have shown that small caliber endoscopy is feasible, safe and well-tolerated. These devices can decrease the potential risks of upper gastrointestinal endoscopy by eliminating the need for sedation since these ultrathin endoscopes induce much less gag reflex or choking sensation in patients. Moreover, gastrointestinal endoscopy with small caliber endoscopes results in less sympathetic system activation as well as less oxygen desaturation compared to standard endoscopy, especially in aged, severely ill, bedridden patients. Nevertheless, there is no overall consensus on its cost effectiveness. Though indications are similar with standard endoscopy, small caliber endoscopy can be preferred in patients with gastrointestinal stenosis. Less common indications include transnasal endoscopic retrograde cholangiography and postpyloric feeding tube insertion. The esophagogastroduodenoscopy procedure with small caliber endoscopes is easy to perform, and there is generally no need for further training for this technique. However, the additional cost of equipment and some medicolegal and technical issues have resulted in the unpopularity of small caliber endoscopy in most countries other than France and Japan. However, sharing information about this technique and stressing its potential advantages can help in its widespread use in various countries including Turkey. We believe that routine use of small caliber endoscopes during daily gastrointestinal endoscopy practice is not far away in many countries.

OBJECTIVES: Our prospective clinical study of prospectively compared physicians' management of submucosal tumors (SMTs) with and without endoscopic ultrasound (EUS). It showed that EUS reduced further tests by more than 50%, but it is unclear whether it reduced the overall costs. The aim of this study was to determine whether EUS would reduce costs. METHODS: Based on the data from the clinical study, a decision analysis was created to compare the direct hospital costs for diagnosing SMTs with and without EUS. Cost data from Germany, Canada, Japan, France, and the United States were used. Costs were expressed as a ratio of the cost of esophagogastroduodenoscopy (EGD). Average cost ratios for each procedure were as follows (sensitivity analysis ranges are 95% CIs): EGD = 1; large particle biopsy (LPB) 0.75 (0.22-1.24); endoscopic ultrasound (EUS) 2.0 (1.22-2.79); abdominal ultrasound (US) 0.77 (0.31-1.24); computed tomography (CT) 1.79 (0.64-2.95); magnetic resonance imaging (MRI) 3.54 (1.28-5.79); and ERCP 3.45 (0.82-6.07). RESULTS: Initial inputs show the "no EUS" strategy is less costly when cost data for all countries are averaged (expected cost 2.13 vs 2.71, expressed as a ratio of the cost of EGD]) and for all countries individually except Germany. In descending order, overall management costs were most sensitive to the relative costs of CT and EUS, the cost of LPB, and to the probability of no further testing when the "no EUS" strategy is used. However, threshold analysis showed that changes in only one variable, the ratio of the cost of EUS compared to CT (the "EUS/CT ratio"), were able to shift the optimal strategy from "no EUS" to "EUS." "EUS" becomes less costly only if the EUS/CT cost ratio is <0.85 (i.e., if the cost of EUS is <85% that of CT). If the potential for EUS to reduce severe complications caused by LPB of high risk lesions is incorporated, "EUS" is less costly if this risk is >2% (range 1-5%). CONCLUSIONS: When used to diagnose SMTs, EUS may reduce the need for further tests but not necessarily costs. For this indication, the relative cost of EUS compared with CT is what most limits its potential value as a cost-minimizing test. The costs, economic impact, and hence the relative appropriateness of EUS and other procedures may vary in different health care systems.
