AIM To assess the incremental benefit of narrow band imaging(NBI) and white light endoscopy(WLE), randomizing the initial technique for the detection of residual neoplasia at the polypectomy scar after an endoscopic piecemeal mucosal resection(EPMR).METHODS We conducted an observational study in an academic center to assess the incremental benefit of NBI and WLE randomly applied 1:1(NBI-WLE or WLE-NBI) in the follow-up of a post-EPMR scar by the same *** A total of 112 EPMR scars were included. The median baseline polyp size was 20 mm(interquartile range: 14-30). At first review, NBI and WLE showed good sensitivity(85.0% vs 78.9%), specificity(77.1% vs 84.2%) and overall accuracy(80.0% vs 82.5%). NBI after WLE(WLE-NBI group) improved accuracy, but this difference was not statistically significant [area under the curve(AUC): 86.8% vs 81.6%, P = 0.15]. WLE after NBI(NBI-WLE group) did not improve accuracy(AUC: 81.4% vs 81.1%, P = 0.9). Overall, recurrence was found in 39/112(34.8%) *** Although no statistically significant differences were found between the two techniques at the first postEPMR assessment, the use of NBI after WLE may improve residual neoplasia detection. Nevertheless, biopsy is still required in the first scar review.

AIM: To investigate the clinical impact of capsule endoscopy(CE) after an obscure gastrointestinal bleeding(OGIB) episode, focusing on diagnostic work-up, followup and predictive factors of rebleeding. METHODS: Patients who were referred to Hospital del Mar(Barcelona, Spain) between 2007 and 2009 for OGIB who underwent a CE were retrospectively analyzed. Demographic data, current treatment with non-steroid antiinflammtory drugs or anticoagulant drugs, hemoglobin levels, transfusion requirements, previous diagnostic tests for the bleeding episode, as well as CE findings(significant or non-significant), work-up and patient out-comes were analyzed from electronic charts. Variables were compared by χ 2 analysis and Student t test. Risk factors of rebleeding were assessed by Log-rank test, Kaplan-Meier curves and Cox regression model. RESULTS: There were 105 patients [45.7% women, median age of 72 years old(interquartile range 56-79)] and a median follow-up of 326 d(interquartile range 123-641) included in this study. The overall diagnostic yield of CE was 58.1%(55.2% and 63.2%, for patients with occult OGIB and overt OGIB, respectively). In 73 patients(69.5%), OGIB was resolved. Multivariate analysis showed that hemoglobin levels lower than 8 g/dL at diagnosis [hazard ratios(HR) = 2.7, 95%CI: 1.9-6.3], patients aged 70 years and above(HR = 2.1, 95%CI: 1.2-6.1) and significant findings in CE(HR = 2.4, 95%CI: 1.1-5.8) were independent predictors of rebleeding. CONCLUSION: One third of the patients presented with rebleeding after CE; risk factors were hemoglobin levels < 8 g/dL, age ≥ 70 years or the presence of significant lesions.
