“…Although the lesion recognition ability of the CE trainees enrolled in our study was low, consistent with previous reports [24-27], use of FICE setting 1 or 2 improved the detectability of angioectasia and erosions/ulcerations by the CE trainees. Imagawa et al reported from a study of CE experts, that CE-FICE improved the detectability of angioectasia, but not that of erosions/ulcerations [28].…”

BackgroundCapsule endoscopy with flexible spectral imaging color enhancement (CE-FICE) has been reported to improve the visualization and detection of small-bowel lesions, however, its clinical usefulness is still not established. Therefore, we conducted a study to evaluate whether CE-FICE contributes to improve the detectability of small-bowel lesions by CE trainees.MethodsFour gastroenterology trainees without prior CE experience were asked to read and interpret 12 CE videos. Each of the videos was read by conventional visualization method and under three different FICE settings. To evaluate whether the lesion recognition ability of the CE trainees could be improved by the FICE technology, the lesion detection rate under each of the three FICE settings was compared with that by conventional CE. CE trainees tend to miss small-bowel lesions in bile-pigment-positive condition, therefore we evaluated whether CE-FICE contributes to reducing the bile-pigment effect. The bile-pigment condition was determined by the color values around the small-bowel lesions according to the results of the receiver-operating-characteristic analysis. Moreover, we also evaluated whether poor bowel preparion might affect the accuracy of lesion recognition by CE-FICE.ResultsOf a total of 60 angioectasias, CE trainees identified 26 by conventional CE, 40 under FICE setting 1, 38 under FICE setting 2, and 31 under FICE setting 3. Of a total of 82 erosions/ulcerations, CE trainees identified 38 by conventional CE, 62 under FICE setting 1, 60 under FICE setting 2, and 20 under FICE setting 3. Compared with conventional CE, FICE settings 1 and 2 significantly improved the detectability of angioectasia (P = 0.0017 and P = 0.014, respectively) and erosions/ulcerations (P = 0.0012 and P = 0.0094, respectively). Although the detectability of small-bowel lesions by conventional CE (P = 0.020) and under FICE setting 2 (P = 0.0023) was reduced by the presence of bile-pigments, that under FICE setting 1 was not affected (P = 0.59). Our results also revealed that in poor bowel visibility conditions, CE-FICE yielded a high rate of false-positive findings.ConclusionsCE-FICE may reduce the bile-pigment effect and improve the detectability of small-bowel lesions by CE trainees; the reliability of CE-FICE may be improved by good bowel preparation.

“…Attending a practical CE course has been shown to significantly improve lesion recognition and classification skills 59. Web-based learning methods with demonstrable knowledge gains have also been documented; however, these have not been publicly available 60. The value of hands-on training courses has been reflected in published training recommendations by the American Society for Gastrointestinal Endoscopy, which include completion of a hands-on course, in addition to supervised video reporting following completion of a GI fellowship 58…”

Capsule endoscopy remains at the forefront of small bowel investigation, offering the only non-invasive means of directly imaging the mucosa of the small bowel. Recommended for the investigation of obscure gastrointestinal bleeding, Crohn's disease, coeliac disease, small bowel tumours and hereditary polyposis syndromes, the uptake of small bowel capsule endoscopy has been widespread in the UK. However, despite a wealth of published literature supporting the utility of capsule endoscopy in clinical practice, there are limited data regarding the actual practical aspects of service delivery, training and quality assurance. In this article, we attempt to address this by considering specific factors that contribute to provision of a high-quality capsule service. The role of formal training, accreditation and quality assurance measures is also discussed.

“…To practise independently the ASGE requires completion of a 2-year training fellowship, upper and lower gastrointestinal endoscopy (including enteroscopy) competence, attendance at a hands-on training course and supervised reading of at least 10 videos 26. This is easier to achieve than in conventional endoscopy (which requires training in instrument handling) as image interpretation skills can be taught using de-identified training videos in a time-flexible manner, perhaps even using web-based learning 27. Even if UK training programmes adopt a higher minimum of supervised procedures before independent practice, accreditation in capsule endoscopy should be possible for most UK trainees.…”

Objective To determine the location and use of small bowel endoscopy services in the UK and to analyse training uptake to assess future demand and shape discussions about training and service delivery. Design Surveys of British Society of Gastroenterology (BSG) members by webbased and personal contact were conducted to ascertain capsule endoscopy practice and numbers of procedures performed. This was compared with expected numbers of procedures calculated using BSG guidelines, hospital episode statistics and published data of capsule endoscopy in routine practice. Analysis of data from two national training courses provided information about training. Results 45% of UK gastroenterology services offered in-house capsule endoscopy. 91.3% of survey responders referred patients for capsule endoscopy; 67.7% felt that local availability would increase referrals. Suspected small bowel bleeding and Crohn's disease were considered appropriate indications by the majority. Demand is increasing in spite of restricted use in 21.6% of centres. Only two regions performed more than the minimum estimate of need of 45 procedures per 250 000 population. Eight centres perform regular device-assisted enteroscopy; 14 services are in development. 74% of trainees were interested in training and of those training in image interpretation, 67% are doctors and 28% are nurses. Conclusions Capsule endoscopy is used by the majority of UK gastroenterologists but appears to be underused. Current demand for device-assisted enteroscopy seems likely to be matched if new services become established. Future demand is likely to increase, however, suggesting the need to formalise training and accreditation for both doctors and nurses.
