Abstract Background and study aims Capsule endoscopy (CE) is the preferred method for small bowel (SB) exploration. Its diagnostic yield can be reduced by poor mucosal visualization. We aimed to evaluate three electronic parameters – colorimetry, abundance of bubbles, and brightness – to assess the adequacy of mucosal visualization of SB-CE images. Patients and methods Six-hundred still images were randomly extracted from 30 complete and normal SB-CEs. Three experts independently evaluated these images according to a 10-point assessment grid. Any frame with a mean score above seven was considered adequately cleansed. Each image was analyzed electronically according to the three preset parameters, individually and then combined, with the experts' score as reference. A random forests methodology was used for machine learning and testing. Results The combination of the three electronic parameters achieved better discrimination of adequately from inadequately cleansed frames as compared to each individual parameter taken separately (sensitivity 90.0 % [95 %C. I. 84.1 – 95.9], specificity 87.7 % [95 %C. I. 81.3 – 94.2]). Conclusion This multi-criterion score constitutes a comprehensive, reproducible, reliable, automated and rapid cleansing score for SB-CE frames. A patent is pending at the European patent office.

Introduction. The small bowel capsule endoscopy is the first line procedure in patients with suspected small bowel bleeding. Data regarding overt suspected small bowel bleeding and its predictive factors remain still limited. Aim. To assess the diagnostic yield of the capsule endoscopy and the factors predicting positive findings in patients with overt suspected small bowel bleeding. Methods. Patients with overt suspected small bowel bleeding (melena or enterorrhagia) and negative upper and lower endoscopy were included. A positive diagnostic yield was considered when the capsule endoscopy diagnosed one or more P2 or P3 type lesions (Modified Saurin Classification) Demographic and laboratory data were recorded. Results. 79 patients were included (mean age 62.92 (15-89); F:M 46:33). The diagnostic yield of the capsule endoscopy was 62%. The most frequent finding was angioectasia (44.8%), followed by nonspecific inflammation/ulceration (20.4%). The multivariate analysis found that age older than 50 years and male sex were independent variables that were associated with an increased risk of positive findings and angioectasia. Conclusions. In this group of patients with overt suspected small bowel bleeding, the capsule endoscopy was useful (with a diagnostic yield of 62%). The most frequent lesions were the vascular ones. Age over 50 and male sex were independent predictors of finding lesions and angioectasia.

Abstract Background Small-bowel capsule endoscopy is advocated and repeat upper gastrointestinal (GI) endoscopy should be considered for evaluation of recurrent or refractory iron deficiency anemia (IDA). A new device that allows magnetic steering of the capsule around the stomach (magnetically assisted capsule endoscopy [MACE]), followed by passive small-bowel examination might satisfy both requirements in a single procedure. Methods In this prospective cohort study, MACE and esophagogastroduodenoscopy (EGD) were performed in patients with recurrent or refractory IDA. Comparisons of total (upper GI and small bowel) and upper GI diagnostic yields, gastric mucosal visibility, and patient comfort scores were the primary end points. Results 49 patients were recruited (median age 64 years; 39 % male). Combined upper and small-bowel examination using the new capsule yielded more pathology than EGD alone (113 vs. 52; P < 0.001). In upper GI examination (proximal to the second part of the duodenum, D2), MACE identified more total lesions than EGD (88 vs. 52; P < 0.001). There was also a difference if only IDA-associated lesions (esophagitis, altered/fresh blood, angioectasia, ulcers, and villous atrophy) were included (20 vs. 10; P = 0.04). Pathology distal to D2 was identified in 17 patients (34.7 %). Median scores (0 – 10 for none – extreme) for pain (0 vs. 2), discomfort (0 vs. 3), and distress (0 vs. 4) were lower for MACE than for EGD (P < 0.001). Conclusion Combined examination of the upper GI tract and small bowel using the MACE capsule detected more pathology than EGD alone in patients with recurrent or refractory IDA. MACE also had a higher diagnostic yield than EGD in the upper GI tract and was better tolerated by patients.

The Cost

Capsule endoscopy (CE) has proven to be a valuable diagnostic modality for small bowel diseases over the past 20 years, particularly Crohn’s disease (CD), which can affect the entire gastrointestinal tract from the mouth to the anus. CE is not only used for the diagnosis of patients with suspected small bowel CD, but can also be used to assess disease activity, treat-to-target, and postoperative recurrence in patients with established small bowel CD. As CE can detect even mildly non-specific small bowel lesions, a high diagnostic yield is not necessarily indicative of high diagnostic accuracy. Moreover, the cost effectiveness of CE as a third diagnostic test employed usually after ileocolonoscopy and MR or CT enterography is an important consideration. Recently, new developments in colon capsule endoscopy (CCE) have increased the utility of CE in patients with ulcerative colitis (UC) and pan-enteric CD. Although deflation of the colon during the examination and the inability to evaluate dysplasia-associated lesion or mass results in an inherent risk of overestimation or underestimation, the convenience of CCE examination and the risk of flare-up after colonoscopy suggest that CCE could be used more actively in patients with UC.

The Impact

Objectives.Small bowel capsule endoscopy (SBCE) plays a decisive role in the obscure gastrointestinal bleeding (OGIB) diagnosis. Antithrombotics may increase bleeding risk in patients with preexistent lesions or through direct mucosal aggression. We aimed to correlate antithrombotics usage with lesions with bleeding potential found in SBCE.Methods.Retrospective single-center study including 274 consecutive SBCE performed over 7 years for OGIB. The lesions were classified as P0 (no bleeding potential), P1 (uncertain bleeding potential: erosions), and P2 (high bleeding potential: angioectasias, ulcers, and tumors). We assessed antiplatelet and anticoagulant drug use during the 60 days preceding SBCE.Results.One-third of the patients were under antithrombotic therapy. The diagnostic yield of SBCE for P2 lesions was 30.0%. Angioectasias (20.4%) were the most frequently observed lesions. There was a significant correlation between anticoagulant drug use and a higher incidence of P2 lesions in the small bowel (43.2% versus 26.5%; OR = 2.11,P=0.026). We found no significant correlation between antiplatelets and lesions with bleeding potential in SBCE.Conclusions.Small bowel lesions with high bleeding potential were more frequently detected when the patient was on anticoagulant drugs, resulting in a twofold risk. Antiplatelet drugs were not associated with small bowel lesions.

Valuable Diagnostic Tool

Abstract Background Terminal ileitis (TI), is a common condition in clinical practice and may be associated with a wide variety of diseases. Small bowel capsule endoscopy (SBCE) is a valuable diagnostic tool for small bowel diseases; however, data regarding its diagnostic impact on isolated TI are sparse. The aim of the study was to evaluate the diagnostic value of SBCE for isolated TI detected during ileocolonoscopy. Methods Retrospective study including consecutive patients undergoing SBCE after diagnosis of TI without colonic mucosal abnormalities on ileocolonoscopy between January 2016 and September 2019. Demographic, clinical, biochemical, endoscopic and imaging data were collected. Results One hundred and two patients with isolated ileitis on ileocolonoscopy were included. Positive findings on SBCE were found in 84 (82.4%) patients, being ulcers the most common finding (76.5%). Endoscopic abnormalities proximal to terminal ileum were found in 36.3% of patients. After SBCE, 63.7% of patients had a final diagnosis, Crohn’s disease (CD) was the most common (34.3%), followed by NSAIDs enteropathy (12.7%). Elevated faecal calprotectin (p = 0.001) was independently associated with positive SBCE findings. There was a tendency for high levels of erythrocyte sedimentation rate be associated with positive findings (p = 0.07). However, the presence of symptoms, imaging abnormalities and other laboratory findings such as leukocytosis, anaemia, and elevated C-reactive protein were not predictors of positive SBCE findings. At multivariate analysis, only elevated faecal calprotectin (OR 6.0, IC 95% 1.9–18.7; p = 0.002) was a significant predictive factor for positive SBCE findings. Conclusion SBCE revealed a high diagnostic yield in patients with isolated ileitis on ileocolonoscopy enabling a definite diagnosis in almost two-thirds of patients. Approximately one-third of patients had findings proximal to terminal ileum and a similar percentage was diagnosed with CD. In patients with isolated ileitis on ileocolonoscopy, SBCE should be considered to evaluate small bowel lesions, particularly when there is an elevated faecal calprotectin, even when other clinical, imagiological or laboratorial abnormalities are absent.
