“…Interestingly, in our study the ampulla of Vater was identified in 33% of patients. Although this is lower to the detection rate (71%) reported by Friedrich et al [17], it is still substantially higher to the rate observed in studies performed with frontal-view VCEs irrespectively of field of view, number of cameras and/or frame-rate [7][8][9][10].…”

“…According to previous studies [7][8][9][10], the visualization of this landmark of the proximal small bowel is regarded as a surrogate marker of an adequate visualization of the proximal small bowel overall. Interestingly, in our study the ampulla of Vater was identified in 33% of patients.…”

“…Nonetheless, several studies demonstrated that the visualization of the small bowel with forward-viewing capsules is suboptimal [1][2][3][6][7][8][9][10][11][12][13][14]. First, the exploration of the entire small bowel can be achieved only in about 80% of patients [1][2][3]6].…”

“…First, the exploration of the entire small bowel can be achieved only in about 80% of patients [1][2][3]6]. Furthermore, VCE can miss about 30% of discrete lesions, especially in the proximal segments where passive capsules are rapidly propelled by gut motility [7][8][9][10]. Finally, image interpretation for lesions appearing in a single frame, mucosal bulges and/or segments with inadequate bowel cleansing can be challenging even for expert readers [11][12][13][14].…”

“…Two studies evaluated the ability of CE to detect the major duodenal papilla as surrogate marker and reported the sensitivity of 10.4% and 43.6%. 7,8 One study validated the effectiveness of CE in patients with OGIB based on the outcome after 12 months of follow-up. 9 The best method to estimate the diagnostic sensitivity and specificity of CE is to compare the result of CE with the reliable gold standard, or intraoperative enteroscopy.…”

Background/Aims: Video capsule endoscopy (CE) can provide a negative result despite the presence of clinically significant small-bowel lesions. We therefore performed a prospective study to elucidate whether repeated back-to-back CE increases the diagnostic yield over a single CE in patients with obscure gastrointestinal bleeding (OGIB). Methods: Sixteen patients with OGIB were prospectively enrolled and underwent back-to-back CE investigation with a 24-hour interval. All CE videos were interpreted by two experienced readers at a maximum 15 frames/second in a random order. Results: The diagnostic yield of the single CE was 37.5% for the first CE, 43.8% for the second CE, and 62.5% for the back-to-back CE. The overall mean lesion-detection rates of the first and second CEs were 42.2% and 64.6%, respectively. The bowel preparation status of the second CE was improved in 37.5% and unchanged in 62.5% of cases as compared with that of the first CE. Conclusions: These results indicate that back-to-back CE may increase the diagnostic yield and lesion-detection rate over a single CE in patients with OGIB. Therefore, if the first CE is not diagnostic in a patient with OGIB, repeat back-to-back CE may be considered as a candidate for further workup. (Gut Liver 2010;4:54-59)
