Abstract
Surveillance endoscopy of non-dysplastic Barrett's esophagus (NDBE) that fails to detect intestinal metaplasia (IM), or negative surveillance, is known to occur in clinical practice, although the frequency and possible outcomes in a large cohort in clinical practice is not well described. The goals of this study were to define frequency in which negative surveillance occurs and endoscopic outcomes in a screening cohort of short segment NDBE. A retrospective cohort (n = 184) of patients newly diagnosed with short segment NDBE at an outpatient academic tertiary care center between 2003 and 2011 were reviewed. Only those with one or more surveillance endoscopies were included to define a frequency of negative surveillance. Included patients were further assessed if they had two or more surveillance endoscopies and were classified into groups as sampling error or negative IM on consecutive surveillances based on the results of their surveillance endoscopies. The frequency of a negative surveillance endoscopy in all short-segment NDBE patients was 19.66% (92 endoscopic exams were negative for IM of 468 total surveillance exams). A negative surveillance endoscopy occurred in 40.76% (n = 75) patients. Sampling error occurred in 44.12% and negative IM on consecutive surveillance endoscopies in 55.88% of those with ≥ 2 surveillance endoscopies and an initially negative surveillance exam. The frequency of negative IM on consecutive surveillances was 19.00% of all patients who had two surveillance endoscopies. When the index diagnostic Barrett's esophagus segment length was < 1 cm, 32.14% (18/56) of all patients (with ≥ 2 surveillance endoscopies) had negative IM on consecutive surveillance endoscopies. Negative surveillance occurs frequently in short-segment NDBE. When an initial negative surveillance endoscopy occurs, it may be due to either a sampling error or lack of detectable IM on surveillance exam. When a <1 cm segment of NDBE is diagnosed, a significant proportion of patients may go on to have continuously undetected IM on consecutive surveillance endoscopic exams without intervention.

Abstract
Current guidelines for endoscopic surveillance of Barrett's esophagus (BE) recommend that patients with newly diagnosed BE undergo confirmatory esophagogastroduodenoscopy (EGD) to exclude the presence of dysplasia. The extent to which confirmatory endoscopy alters management and detects missed dysplasia in newly diagnosed BE has not been reported. The frequency with which confirmatory endoscopy changed surveillance management in patients with newly diagnosed BE was assessed. A two center cohort analysis was conducted on patients newly diagnosed with BE. The rate of dysplasia on confirmatory endoscopy for patients who had nondysplastic BE was obtained. Demographic and endoscopic variables were assessed for association with dysplasia detection using Firth logistic regression model. Out of the 146 patients newly diagnosed with BE and initially determined to be without dysplasia, 12 had dysplasia on the confirmatory second EGD (8.2%). Eleven of 12 cases with dysplasia on confirmatory endoscopy had long-segment BE (LSBE). Among all the LSBE cases in our cohort, 11 had newly diagnosed dysplasia on confirmatory EGD, 29.7% (11/37). The average number of biopsies obtained from the 11 LSBE cases with dysplasia was comparable with the rest of the LSBE cases without dysplasia (6.73 and 5.42, respectively, P-value 0.205). The rate of dysplasia detection in short-segment BE (SSBE) was much lower, 0.95% (1 out of 105). There were no cases of high-grade dysplasia (HGD) or cancer detected in any SSBE case. HGD was detected on confirmatory EGD in two cases, both were LSBE. Segment length was the only statistically significant factor to predict the presence of dysplasia on confirmatory endoscopy (odds ratio 9.158, P. 0.008). Confirmatory EGD in newly diagnosed LSBE had significant rate of dysplasia detection (29.7%) in this cohort. Among patients with SSBE, there was a low rate of dysplasia detection with confirmatory EGD, less than 1% of cases. No additional cases of HGD or esophageal carcinoma in SSBE cases were detected. This suggests that the yield of confirmatory EGD is greater in patients with LSBE.

Abstract
Adherence to practice guidelines for endoscopic surveillance of Barrett's esophagus is equivocal with evidence of underutilization and overutilization. While physicians report strong agreement with and adherence to recommended surveillance endoscopy (esophagogastroduodenoscopy [EGD]) guidelines, less is known about modifiable barriers and facilitators shaping patients' adherence behaviors. The aim of this study is to conduct a structured literature review of studies exploring patients' perspectives regarding surveillance EGD and to place these results within a conceptual framework. A structured literature review of PubMed, Cochrane, and Google Scholar databases with qualitative thematic analysis was performed. Six studies met eligibility criteria. Analysis of results identified five distinct themes. First, patients' objective cancer risk estimates are consistent with subjective risk perceptions, but neither is associated with EGD surveillance. Second, patients have strong beliefs in the benefits of cancer screening and surveillance and trust in their doctors. Third, anxiety and depression symptoms are related to risk perceptions and outcome expectancies of surveillance. Fourth, endoscopic surveillance itself has affective and physical consequences. Finally, health services and system variables are related to risk perception and EGD surveillance. These themes coherently fit within an integrated model of intuitive decision-making and health behaviors. Studies meeting eligibility criteria were heterogeneous in terms of their study objectives and findings. Quantitative meta-analyses of study findings could not be performed. To improve adherence, endoscopic surveillance programs should consider how patients intuitively frame risks and benefits and patients' emotional reactions to the endoscopy procedure, and focus on how physicians communicate recommendations.

Abstract
The practice for endoscopic surveillance of Barrett's oesophagus has evolved from "blind" or random 4 quadrant biopsies (Seattle protocol) to a more "intelligent" targeted biopsy approach. This evolution has been possible due to the rapid advances in endoscopic imaging technology and expertise in the last decade. Previous endoscopes had relatively poor image resolution that often did not allow the subtle mucosal changes associated with dysplastic Barrett's mucosa to be identified. Newer endoscopic imaging techniques available today may allow endoscopists to identify areas of dysplasia or malignancy and target biopsies accordingly. These modalities which include narrow band imaging, chromoendoscopy, autofluorescence imaging, and confocal endomicroscopy as well as a few novel imaging modalities on the horizon will be discussed further.

Abstract
PURPOSE OF REVIEW This article discusses the various management options and gaps in knowledge in our current understanding of the epidemiology and neoplastic progression of Barrett's esophagus and how this affects the decision to treat patients with nondysplastic Barrett's esophagus (NDBE). RECENT FINDINGS Barrett's esophagus is the only known risk factor for esophageal adenocarcinoma (EAC), the most rapidly rising cancer in terms of incidence in the United States. The current management strategy is to enroll patients with Barrett's esophagus in surveillance programs. Despite these efforts, the incidence of EAC has continued to rise. Recent studies have shown endoscopic ablation therapies to be relatively safe and effective in the eradication of NDBE. However, all studies performed to date were cohort in nature with no randomized controlled trial data available at this time. At present, several critical questions remain unanswered: Will treatment of NDBE eliminate the risk of developing cancer? If not, just how effective is the treatment? Is it durable? Can surveillance be stopped after ablation? What are the risks? Would such treatment be cost-effective? SUMMARY It is possible that if future data can affirmatively answer some of these questions, ablation of NDBE would be reasonable in selected patients; however, until then, a wait and watch approach is likely to be the best option for most low-risk patients.

Abstract
Interpretation of exploding knowledge about Barrett's esophagus is impaired by use of several conflicting definitions. Because any histological type of esophageal columnar metaplasia carries risk for esophageal adenocarcinoma, the diagnosis of Barrett's esophagus should no longer require demonstration of intestinal-type metaplasia. Endoscopic recognition and grading of Barrett's esophagus remains a significant source of ambiguity. Reflux disease is a key factor for development of Barrett's esophagus, but other factors must underlie its development, since it occurs in only a minority of reflux disease patients. Neither antireflux surgery nor proton pump inhibitor (PPI) therapy has major impacts on cancer risk. Within a year, a major trial should indicate whether low-dose aspirin usefully reduces cancer risk. The best referral centers have transformed the accuracy of screening and surveillance for early curable esophageal adenocarcinoma by use of enhanced and novel endoscopic imaging, visually-guided, rather than blind biopsies and by partnership with expert pathologists. General endoscopists now need to upgrade their skills and equipment so that they can rely mainly on visual targeting of biopsies on mucosal areas of concern in their surveillance practice. General pathologists need to greatly improve their interpretation of biopsies. Endoscopic therapy now achieves very high rates of cure of high-grade dysplasia and esophageal adenocarcinoma with minimal morbidity and risk. Such results will only be achieved by skilled interventional endoscopists. Esophagectomy should now be mainly restricted to patients whose cancer has extended into and beyond the submucosa. Weighing risks and benefits in the management of Barrett's esophagus is difficult, as is the process of adequately informing patients about their specific cancer risk.
