[PMID: 36007583 DOI: 10.1016/j.gie.2022.08.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 03/17/2022] [Accepted: 08/19/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND AND AIMS Visible lesion (VL) detection is essential in patients with Barrett's esophagus (BE). We sought to assess the rate of VL detection by academic and community endoscopists using high-definition white-light endoscopy (HD-WLE) and narrow-band imaging (NBI) during surveillance endoscopy. METHODS Fifty endoscopists were invited to participate in a prospective video survey study. Participants viewed 25 standardized clips of patients referred for endoscopic therapy. Participants noted identification of anatomic landmarks and VLs using HD-WLE and NBI and reported practice-level data. The criterion standard of VL identification was established by consensus of 5 BE experts. Our primary outcome was the rate of VL identification using HD-WLE and NBI. RESULTS Forty-four of 50 participants completed the study (22 academic and 22 community). Compared with the criterion standard, participants did not identify 28% (HD-WLE) and 31% (NBI) of VLs. Community endoscopists had more experience (>5 years in practice: community 85% vs academic 54.5%, P = .041; >5 surveillance endoscopies a month: community 85% vs academic 31.8%, P = .046). Across all participants, VL detection using NBI improved significantly with a minimum of 5 surveillance endoscopies per month (area under the curve = .72; 95% confidence interval, .56-.85; P = .006). CONCLUSIONS Despite improved endoscope resolution and availability of virtual chromoendoscopy, the overall rate of VL detection remains low. Identification of VLs using NBI may be volume dependent. Further education and training efforts focused on VL detection during BE surveillance endoscopy are needed.

Abstract
Barrett's esophagus is the precursor lesion for esophageal adenocarcinoma. The goals of endoscopic surveillance are to detect dysplasia and early esophageal adenocarcinoma in order to improve patient outcomes. Despite the ongoing debate regarding the efficacy of surveillance, all current gastrointestinal societies recommend surveillance at this time. Optimal surveillance technique includes adequate inspection time, evaluation using high-definition white light and chromoendoscopy, appropriate documentation of the metaplastic segment using the Prague C & M criteria as well as the Paris classification should lesions be found, utilization of the Seattle biopsy protocol, and endoscopic resection of visible lesions.

Abstract
Sampling error during screening and surveillance endoscopy is a well-recognized problem. Wide-area transepithelial sampling with three-dimensional computer-assisted analysis (WATS3D), used adjunctively to forceps biopsy (FB), has been shown to increase the detection of Barrett's esophagus (BE) and BE-associated neoplasia. We evaluated the clinical utility of WATS3D and its impact on the management of patients with BE and dysplasia. Between 2013 and 2018, 432 consecutive patients who had a WATS3D positive and an accompanying FB negative result were identified. Physicians were contacted to determine if the WATS3D result impacted their decision to enroll patients in surveillance or increase the frequency of surveillance, recommend ablation, and/or initiate or increase the dose of proton pump inhibitors (PPIs). WATS3D directly impacted the management of 97.8% of 317 BE patients; 96.2% were enrolled in surveillance and 60.2% were started on PPIs or their dose was increased. WATS3D impacted the management of 94.9% and 94.1% of the 98 low-grade dysplasia and 17 high-grade dysplasia patients, respectively. As a result of WATS3D, 33.7% of low-grade dysplasia and 70.6% of high-grade dysplasia patients underwent endoscopic therapy. More than 37% of all dysplasia patients were enrolled in a surveillance program, and nearly 30% were scheduled to be surveilled more frequently. PPIs were either initiated, or the dose was increased in more than 54% of all dysplasia patients. We demonstrate that WATS3D has high clinical utility. By prompting physicians to change their clinical management in patients with negative FB results, WATS3D, used adjunctively to FB, directly impacts patient management, and improves patient outcomes.

Abstract
Background and study aims: Barrett's esophagus is a premalignant condition in the distal esophagus associated with esophageal adenocarcinoma. Since gastroesophageal reflux is known to be of etiological importance in both Barrett's esophagus and esophageal adenocarcinoma, we aimed to study which endoscopic alterations at the Z-line can be attributed to a previous history of reflux symptoms. Patients and methods: From 1988, a population cohort in Sweden has been prospectively studied regarding gastrointestinal symptoms, using a validated questionnaire. In 2012, the population was invited to undergo a gastroscopy and participate in the present study. In order to determine which endoscopic alterations that can be attributed to a previous history of gastroesophageal reflux, three different endoscopic definitions of columnar-lined esophagus (CLE) were used: (1) ZAP I, An irregular Z-line with a suspicion of tongue-like protrusions; (2) ZAP II/III, Distinct, obvious tongues of metaplastic columnar epithelium; (3) CLE ≥1 cm, The Prague C/M-classification with a minimum length of 1 cm. Results: A total of 165 community subjects were included in the study. Of these, 40 had CLE ≥ 1 cm, 99 had ZAP I, and 26 had ZAP II/III. ZAP II/III was associated with an over threefold risk of previous GER symptoms (OR: 3.60, CI: 1.49-8.70). No association was found between gastroesophageal reflux and ZAP I (OR: 2.06, CI: 0.85-5.00), or CLE ≥1 cm (OR: 1.64, CI: 0.77-3.49). Conclusions: In a general community, the only endoscopic alteration to the Z-line definitely linked to longstanding GER symptoms was the presence of obvious tongues of metaplastic columnar epithelium (ZAP II/III).

Abstract
Current endoscopic surveillance protocols for Barrett's oesophagus have several limitations, mainly the poor cost-effectiveness and high miss rate. However, there is sufficient evidence that patients enrolled in a surveillance program have better survival chances of oesophageal cancer due to earlier tumor stages at diagnosis compared to patients with de novo diagnosed oesophagus cancer. Risk stratifications aim to identify patients at highest risk of developing adenocarcinoma of the oesophagus; most of them base on the length of the Barrett's segment and the presence of dysplasia. This review discusses prognostic factors and provides practical guidance on how to improve the efficacy and outcome in Barrett's surveillance programs.

Abstract
BACKGROUND & AIMS Guidelines recommend endoscopic surveillance of patients with Barrett's esophagus (BE) to identify those with dysplasia (a precursor of carcinoma) or early-stage esophageal adenocarcinoma (EAC) who can be treated endoscopically. However, it is unclear whether surveillance increases survival times of patients with BE. We performed a systematic review and meta-analysis to qualitatively and quantitatively examine evidence for the association of endoscopic surveillance in patients with BE with survival and other outcomes. METHODS We searched publication databases for studies reporting the effects of endoscopic surveillance on mortality and other EAC-related outcomes. We reviewed randomized controlled trials, case-control studies, studies comparing patients with BE who received regular surveillance with those who did not receive regular surveillance, and studies comparing outcomes of patients with surveillance-detected EAC vs symptom-detected EACs. We performed a meta-analysis of surveillance studies to generate summary estimates using a random effects model. The primary aim was to examine the association of BE surveillance on EAC-related mortality. Secondary aims were to examine the association of BE surveillance with all-cause mortality and EAC stage at time of diagnosis. RESULTS A single case-control study did not show any association between surveillance and EAC-related mortality. A meta-analysis of 4 cohort studies found that lower EAC-related and all-cause mortality were associated with regular surveillance (relative risk, 0.60; 95% CI, 0.50-0.71; hazard ratio, 0.75; 95% CI, 0.59-0.94). Meta-analysis of 12 cohort studies showed lower EAC-related and all-cause mortality among patients with surveillance-detected EAC vs symptom-detected EAC (relative risk, 0.73; 95% CI, 0.57-0.94; hazard ratio, 0.59; 95% CI, 0.45-0.76). Lead- and length-time bias adjustment substantially attenuated/eliminated the observed benefits. Surveillance was associated with detection of EAC at earlier stages. A randomized trial is underway to evaluate the effects of endoscopic surveillance on mortality in patients with BE. CONCLUSIONS In a systematic review and meta-analysis of the effects of surveillance in patients with BE, surveillance as currently performed was associated with detection of earlier-stage EAC and may provide a small survival benefit. However, the effects of confounding biases on these estimates are not fully defined and may completely or partially explain the observed differences between surveyed and unsurveyed patients.

Abstract
Factors that influence the frequency of surveillance endoscopy for nondysplastic Barrett's esophagus are not well understood. The objective of this study is to assess factors which influence the frequency of endoscopic surveillance for Barrett's esophagus, including health insurance/third-party payer status. Cases of nondysplastic Barrett's esophagus undergoing esophagogastroduodenoscopy with biopsy were identified using longitudinal data from the Healthcare Utilization Project database in 2005-2006 and followed through 2011. The threshold for appropriate surveillance utilization was defined as two to four surveillance esophagogastroduodenoscopies over a standardized 5-year period. Patients' insurance status was designated as either Medicare, Medicaid, private, or noninsured. 36,676 cases of nondysplastic Barrett's esophagus were identified. Among these, 4,632 patients (12.6%) underwent between two and four surveillance esophagogastroduodenoscopies in 5 years of follow-up versus 31,975 patients (87.3%) who underwent fewer than two esophagogastroduodenoscopies during follow-up. Multivariate analysis found that Barrett's patients insured through Medicaid (OR 1.273; 95% CI = 1.065-1.522) or without insurance (OR = 2.453; 95% CI = 1.67-3.603) were at increased likelihood of being under-surveilled. This study identified a difference in frequency of surveillance esophagogastroduodenoscopy for Barrett's esophagus by payer status. Patients without health insurance and those whose primary insurance was Medicaid were at increased odds for under-surveillance. These data suggest that a more robust system for tracking and ensuring longitudinal follow-up of patients with Barrett's esophagus, with attention to the uninsured and underinsured population, may be needed to ensure optimal surveillance.

Abstract
Despite the availability of safe and effective endoscopic treatment of Barrett's esophagus (BE)-related dysplasia and neoplasia, the incidence and mortality from esophageal adenocarcinoma (EAC) have continued to increase. This likely stems from the large population of patients that develop EAC outside of a BE screening and surveillance program. Identification of BE with screening followed by enrollment in an appropriate surveillance/risk stratification program could be a strategy to address both the incidence of and mortality from EAC. This article summarizes the rationale and challenges for BE screening, the risk factors for BE, and the currently described BE risk assessment tools.

Abstract
OBJECTIVE Endoscopic surveillance for Barrett's oesophagus (BO) is under discussion given the overall low incidence of neoplastic progression and lack of evidence that it prevents advanced oesophageal adenocarcinoma (OAC). The aim of this study was to evaluate the impact of endoscopic BO surveillance on tumour stage and survival of patients with neoplastic progression. DESIGN 783 patients with BO of at least 2 cm were included in a multicentre prospective cohort and followed during surveillance according to the American College of Gastroenterology guidelines. Cases of high-grade dysplasia and OAC were identified during follow-up. OAC staging was performed according to the 7th UICC-AJCC classification. Survival data were collected and crosschecked using death and municipal registries. Data from patients with OAC in the general population were obtained from the Dutch cancer registry. We compared survival of patients with BO with neoplastic progression during surveillance with those of patients without neoplastic progression and patients with OAC in the general population. RESULTS 53 patients with BO developed high-grade dysplasia or OAC during surveillance. Thirty-five (66%) were classified as stage 0, 14 (26%) as stage 1 and 4 (8%) as stage 2. OAC was diagnosed at an earlier stage during BO surveillance than in the general population (p<0.001). Survival of patients with BO with neoplastic progression was not significantly worse than those of patients without neoplastic progression and similar to survival of patients with stage 0 or stage 1 OAC in the general population. CONCLUSIONS OAC is detected at an earlier stage during BO surveillance than in the general population with good survival rates.

Abstract
Barrett's esophagus (BE) is among the most common conditions encountered by the gastroenterologist. In this document, the American College of Gastroenterology updates its guidance for the best practices in caring for these patients. These guidelines continue to endorse screening of high-risk patients for BE; however, routine screening is limited to men with reflux symptoms and multiple other risk factors. Acknowledging recent data on the low risk of malignant progression in patients with nondysplastic BE, endoscopic surveillance intervals are attenuated in this population; patients with nondysplastic BE should undergo endoscopic surveillance no more frequently than every 3-5 years. Neither routine use of biomarker panels nor advanced endoscopic imaging techniques (beyond high-definition endoscopy) is recommended at this time. Endoscopic ablative therapy is recommended for patients with BE and high-grade dysplasia, as well as T1a esophageal adenocarcinoma. Based on recent level 1 evidence, endoscopic ablative therapy is also recommended for patients with BE and low-grade dysplasia, although endoscopic surveillance continues to be an acceptable alternative. Given the relatively common recurrence of BE after ablation, we suggest postablation endoscopic surveillance intervals. Although many of the recommendations provided are based on weak evidence or expert opinion, this document provides a pragmatic framework for the care of the patient with BE.

Abstract
There is substantial interest in identifying patients with premalignant conditions such as Barrett's esophagus (BE), to improve outcomes of subjects with esophageal adenocarcinoma. However, there is limited consensus on the rationale for screening, the appropriate target population, and optimal screening modality. Recent progress in the development and validation of minimally invasive tools for BE screening has reinvigorated interest in BE screening. BE risk scores combining clinical, anthropometric, and laboratory variables are being developed that may allow more precise targeting of screening to high-risk individuals. This article reviews and summarizes data on recent progress and challenges in screening for BE.

Abstract
OBJECTIVE We aimed to estimate the cost saving (over the next 10 years) by our trust implementing the new British Society of Gastroenterology (BSG) surveillance guidelines for Barrett's oesophagus (BO). DESIGN Retrospective endoscopy database analysis. SETTING Two endoscopy units of St George's Hospital NHS Trust, London. PATIENTS Gastroscopy records between 2009 and 2012 were retrieved and patients with an endoscopic diagnosis of BO were identified. BO segment length was recorded and the presence (or absence) of intestinal metaplasia in the oesophageal biopsy samples was reviewed from pathology databases. Patients were then stratified into risk groups in accordance with the new BSG guidelines. INTERVENTIONS Nil. MAIN OUTCOME MEASURES The projected surveillance costs using the new and the old guidelines were calculated over the next 10 years and the cost saving by the implementation of the new guidelines thus determined. RESULTS The 10 year projected cost saving for our trust by implementing the new BO surveillance guidelines was £720 330 (or £72 033 per annum). Projected across the NHS, implementation of the new guidance may save £100 million over the next 10 years. CONCLUSIONS All trusts should review their Barrett's surveillance population and implement these new recommendations expeditiously.

Abstract
Barrett oesophagus is an important precursor lesion for the development of oesophageal adenocarcinoma (OAC). Upper gastrointestinal endoscopy is the modality most widely used to visualize and biopsy the oesophagus to establish a diagnosis. Additional clues are available at the time of endoscopy that can identify high-risk features known to increase the risk of progression to OAC, such as the length of the Barrett oesophagus segment, length of hiatal hernia and the presence of nodularity or visible endoscopic lesions in this segment. Until molecular biomarkers are identified and validated as adjunctive tools for risk stratification, knowledge of endoscopic features could complement dysplasia grading for risk stratification of patients with Barrett oesophagus and identify subgroups at risk of progression to OAC. This approach would, in turn, facilitate more rational tailoring of endoscopic surveillance. This Review summarizes the current role of endoscopic and histological factors involved in neoplastic progression of Barrett oesophagus to OAC, and provides an overview of the risk-prediction models that have utilized endoscopic and histological factors for risk stratification in patients with Barrett oesophagus.

Abstract
BACKGROUND Screening for Barrett's esophagus (BE) and adenocarcinoma (EAC) is controversial, but interest remains in finding the optimal method. Attitudes on screening within the community are unknown. We aimed to assess these attitudes via a survey. STUDY A mixed-mode survey was conducted in adults >50 years to assess awareness regarding BE, willingness to participate in screening, and preferences regarding method of screening. Methods evaluated were sedated endoscopy (sEGD), unsedated transnasal endoscopy (uTNE) and video capsule (VCE). RESULTS A total of 136 from 413 (33%) adults responded [47% males, mean (SD) age 63 (10.2) years], and 26% of responders knew of BE at baseline. After reading the information on BE, 72% were interested in screening. A history of undergoing screening tests and GI symptoms were predictive of interest. Unsedated techniques were preferred by 64% (VCE: 56% and uTNE: 8%) versus sEGD (36%). CONCLUSIONS The majority of adults were willing to undergo screening for BE/EAC, with a preference for unsedated techniques.

Abstract
BACKGROUND Endoscopic resection followed by ablative therapy is frequently used to treat esophageal high-grade dysplasia or early esophageal adenocarcinoma. AIMS To study outcomes in patients with high-grade dysplasia compared to those with esophageal adenocarcinoma after endoscopic resection. METHODS Retrospective, observational, descriptive, single-centre study from a prospective database. We extracted data from 116 endoscopic resections. Survival was plotted using Kaplan-Meier curves multivariable Cox-proportional hazard assess for possible predictors of survival post-endoscopic resection was performed. RESULTS 116 patients (64 esophageal adenocarcinoma, 52 high-grade dysplasia) underwent endoscopic resection from May 2003 to June 2010. Mean age was 71 ± 11 years for high-grade dysplasia and 72 ± 10 years for esophageal adenocarcinoma. Median follow-up was 17 months. Eighty-five patients had negative margins on endoscopic resection. Five-year survivals for high-grade dysplasia and esophageal adenocarcinoma were 86% (range 68-100%) and 78% (59-96%), respectively. Survival was not significantly different between groups (p=0.20). Overall mortality rate was 10.6% (9/85). At multivariable Cox regression increased Barrett's oesophagus length was associated with worse survival (HR 1.18 [1.06-1.33], p=0.0039). Survival was not affected by the pathology before resection: HR 2.4 [95%CI, 0.70-8.4], p=0.16. CONCLUSIONS Survival in patients with high-grade dysplasia of the oesophagus is similar to those with esophageal adenocarcinoma. Longer Barrett's oesophagus segments are associated with decreased survival.

Abstract
We herein report a rare case of very small Barrett's adenocarcinoma. A 65-year-old man underwent surveillance esophagogastroduodenoscopy (EGD) 3 years after endoscopic submucosal dissection (ESD) for superficial Barrett's adenocarcinoma, which revealed a very small reddish area in the mucosa, 2 mm in diameter, in long-segment Barrett's esophagus. The EGD carried out 1 year later confirmed slight enlargement of the lesion, from 2 mm to 3 mm in diameter. Macroscopic type changed from flat type to slightly depressed type. On narrow-band imaging with magnifying endoscopy, an irregular microstructure and irregular microvasculature became recognizable. It was resected by ESD and diagnosed as mucosal adenocarcinoma with a diameter of only 3 mm.

Abstract
Esophageal adenocarcinoma (EAC) is one of the two most common types of esophageal cancer with alarming increase in incidence and very poor prognosis. Aiming to detect EAC early, currently high-risk patients are monitored using an endoscopic-biopsy approach. However, this approach is prone to sampling error and interobserver variability. Diagnostic tissue biomarkers related to genomic and cell-cycle abnormalities have shown promising results, although with current technology these tests are difficult to implement in the screening of high-risk patients for early neoplastic changes. Differential miRNA profiles and aberrant protein glycosylation in tissue samples have been reported to improve performance of existing tissue-based diagnostic biomarkers. In contrast to tissue biomarkers, circulating biomarkers are more amenable to population-screening strategies, due to the ease and low cost of testing. Studies have already shown altered circulating glycans and DNA methylation in BE/EAC, whereas disease-associated changes in circulating miRNA remain to be determined. Future research should focus on identification and validation of these circulating biomarkers in large-scale trials to develop in vitro diagnostic tools to screen population at risk for EAC development.

Abstract
Barrett's esophagus is a pathologic change of the normal squamous epithelium of the esophagus to specialized columnar metaplasia. Barrett's esophagus is a result of prolonged exposure of the esophagus to gastroduodenal refluxate. Although Barrett's itself is not symptomatic, and, in fact, patients with Barrett's esophagus may be completely asymptomatic, it does identify patients at higher risk of developing esophageal adenocarcinoma. Traditionally, antireflux surgery was reserved for patients with symptoms, because it was believed that antireflux surgery did not eliminate Barrett's esophagus and reduce cancer risk. Rationale for the treatment of Barrett's esophagus beyond treating symptoms of gastroesophageal reflux disease stems from the hope to decrease, if not eliminate, the risk of adenocarcinoma. Treatment options ranged from medical acid suppression without surveillance to resection. Ablation, particularly endoscopic radio-frequency ablation, has become the standard of care for Barrett's esophagus with high-grade dysplasia. It role in nondysplastic or low-grade dysplastic Barrett's is less clear. Combined endoscopic mucosal resection with ablation is effective in nodular high-grade Barrett's esophagus. Resection should be reserved for patients with persistent high-grade dysplasia despite multiple attempts at endoscopic ablation or resection or for patients with evidence of carcinoma.

Abstract
Barrett's esophagus is defined by metaplastic glandular changes to the distal esophagus and is linked to an increased risk of esophageal adenocarcinoma. Controversy exists whether the definition should be limited to intestinal type glands with goblet cells or should be expanded to include non-goblet cell columnar epithelium. Barrett's esophagus may be asymptomatic in a large proportion of the population but screening should be considered for those with certain clinical findings. The diagnosis of Barrett's should be based on the combination of careful endoscopic evaluation and histologic review of the biopsy material. Continued surveillance biopsies may be necessary in cases of indeterminate or low grade dysplasia. Clinical follow-up of patients with high grade dysplasia should be tailored to the individual patient. Development of newer endoscopy techniques including chemoendoscopy, chromoendoscopy and use of biomarkers on frozen tissue have shown some promise of identifying patients at risk for malignancy.

Abstract
Barrett's esophageal (BE) metaplasia is a premalignant condition of the distal esophagus that develops as a consequence of gastroesophageal reflux disease. The progression to carcinogenesis results from progressive dysplastic changes of the metaplastic epithelium through low-grade and then high-grade dysplasia (HGD) to eventually adenocarcinoma of the esophagus. The management of HGD is controversial with proponents for each of the three major management strategies: endoscopic surveillance, endoscopic ablative therapies, and esophagectomy. The aim of the study was to define and discuss the various management strategies of HGD arising from BE metaplasia. There is a paucity of randomized controlled data from which to draw definitive conclusions. All strategies for the management of HGD are reasonable options and are complimentary. BE with HGD is a malignant lesion. A multidisciplinary approach individualizing therapy should be undertaken when possible. Esophageal resection should be reserved for otherwise healthy patients. Endoscopic techniques are viable alternatives to surgery.

Abstract
OBJECTIVES In patients with high-grade dysplasia (HGD) in Barrett's esophagus (BE), it is incompletely known which factors are associated with developing esophageal adenocarcinoma (EAC). We analyzed prior biopsy and follow-up strategies in a large nationwide population-based cohort of patients with HGD in BE, and identified predictors of EAC progression. METHODS Prior biopsy records and follow-up evaluations were studied in patients with HGD in BE diagnosed between 1999 and 2008, using PALGA, a nationwide network and registry of histopathology and cytopathology in the Netherlands. Multivariate Cox proportional hazards regression analysis was performed to identify predictors for prevalent (≤ 6 months) and incident (> 6 months) EAC. RESULTS In total, 827 patients with HGD in BE were included. Follow-up data after HGD diagnosis were available in 699 (85%) patients. In 249 (36%) of these patients, an EAC was detected (14.1 EACs per 100 person-years). The risk of prevalent EAC (n=177) was lower with previous surveillance (hazards ratio 0.7; 95% confidence interval 0.5-0.9), unifocal HGD (0.3;0.2-0.6), diagnosis in a university hospital (0.5;0.3-0.9), endoscopic resection (0.5;0.3-0.7), or ablation (0.0;0.0-0.3); and higher when patients were 65-75 years (1.5;1.04-2.04). After exclusion of prevalent EACs, the progression rate was 4.2 EACs per 100 person-years. The risk of progression to incident EAC (n = 72) was lower with previous surveillance (0.6;0.3-0.9) and ablation (0.2;0.0-0.8), and higher when > 75 years (3.8;2.0-7.2) or with an interval > 6 months between HGD diagnosis and first follow-up (e.g., 7-12 months 2.9;1.3-6.3). CONCLUSIONS In this cohort of patients with HGD in BE, the EAC detection rate was 14.1 per 100 person-years and 4.2 per 100 person-years after excluding prevalent cases. The risk of both prevalent and incident EAC was reduced with previous surveillance and endoscopic treatment, while it was increased with older age.

Abstract
OBJECTIVE To assess the feasibility of unsedated transnasal endoscopy (uTNE) and video capsule endoscopy (VCE) as alternatives to sedated endoscopy (sEGD) as screening tools for Barrett esophagus (BE) and to obtain preliminary estimates of participation rates for sEGD, uTNE, and VCE when used for community BE screening in a population cohort. PATIENTS AND METHODS From February 1, 2009, to May 31, 2010, patients from Olmsted County, Minnesota, who were older than 50 years and had no history of known BE were randomized (stratified by age, sex, reflux symptoms noted in a validated questionnaire) into 3 groups for esophageal evaluation with sEGD, uTNE, or VCE. Participation rates and safety profiles were estimated. RESULTS We contacted 127 patients to recruit 20 for each procedure arm (60 total). The probability of participation was 38% (95% confidence interval [CI], 26%-51%) for sEGD, 50% (95% CI, 35%-65%) for uTNE, and 59% (95% CI, 42%-74%) for VCE. Both uTNE and VCE were well tolerated without adverse effects. BE was identified in 3 patients and esophagitis in 8. CONCLUSION Unsedated techniques may be acceptable, feasible, and safe alternatives to sEGD to screen for BE in the community. TRIAL REGISTRATION clinicaltrials.gov identifier: NCT00943280.

Abstract
High-grade dysplasia in Barrett esophagus is a marker for future development of cancer and for the existence of synchronous cancer. A significant problem in management is intraobserver and interobserver variation in the diagnosis of high-grade dysplasia in Barrett esophagus, the natural history of which is poorly understood; thus, treatment decisions are problematic. The ability to preserve the esophagus with endoscopic mucosal ablation or resection and reduce morbidity of treatment has made endoscopic treatment the mainstay of therapy. Esophagectomy is reserved for treatment failures and for high-grade dysplasia not amenable to less aggressive therapies. This article outlines the data supporting current management strategies.

Abstract
Barrett's esophagus is a well-known risk factor for the development of esophageal adenocarcinoma. Current practice guidelines recommend endoscopic surveillance of patients with Barrett's esophagus in an attempt to detect cancer at an early and potentially curable stage. This review addresses the rationale behind surveillance and criteria for inclusion of patients in surveillance programs as well as the appropriate technique and intervals that should be used. This work addresses other key topics in Barrett's esophagus surveillance, including the efficacy of surveillance programs, physician compliance with surveillance guidelines, cost-effectiveness of surveillance programs, and areas for future research.

Abstract
Chronic esophageal exposure to reflux of gastroduodenal contents can result in complications of GERD including esophageal stricture, Barrett's oesophagus or extraesophageal symptoms such as laryngitis, chronic cough or asthma. Endoscopy is the main diagnostic tool for patients with chronic reflux presenting with dysphagia to visualise esophageal mucosa and identify the underlying pathology. Barrett's oesophagus should be suspected in those with chronic reflux disease. Patients with Barrett's oesophagus should undergo surveillance endoscopy in order to risk stratify to dysplasia or adenocarcinoma. New endoscopic ablative therapies in patients with Barrett's oesophagus and high grade dysplasia are promising new treatment modality for those who may not be candidates for definitive intervention. Given poor sensitivity of diagnostic tests in extraesophageal reflux, empiric therapy with proton pump patients is the initial recommended approach. Diagnostic testing with esophagogastroduodenoscopy and ambulatory pH and impedance monitoring is usually reserved for those unresponsive to acid suppressive therapy. Many uncertainties remain in this group of patients including which patient subgroups might benefit from acid suppressive therapy. Future outcome studies are needed to assess the role of impedance/pH monitoring in this group of patients and to determine who might symptomatically benefit from medical or surgical intervention.

Abstract
The public health importance of Barrett's oesophagus lies in its association with oesophageal adenocarcinoma. The incidence of oesophageal adenocarcinoma has risen at an alarming rate over the past four decades in many regions of the Western world, and there are indications that the incidence of this disease is on the rise in Asian populations in which it has been rare. Much has been learned of host and environmental risk factors that affect the incidence of oesophageal adenocarcinoma, and data indicate that patients with Barrett's oesophagus rarely develop oesophageal adenocarcinoma. Given that 95% of oesophageal adenocarcinomas arise in individuals without a prior diagnosis of Barrett's oesophagus, what strategies can be used to reduce late diagnosis of oesophageal adenocarcinoma?

Abstract
BACKGROUND & AIMS Current surveillance guidelines for Barrett's esophagus (BE) recommend extensive biopsies to minimize sampling error. Biopsy practice patterns for BE surveillance in the community have not been well-described. We used a national community-based pathology database to analyze adherence to guidelines and to determine whether adherence was associated with dysplasia detection. METHODS We identified 10,958 cases of established BE in the Caris Diagnostics pathology database from January 2002-April 2007. Demographic, pathologic, and endoscopic data were recorded. Dysplasia was categorized as low grade, high grade, or adenocarcinoma. Adherence was defined as > or =4 esophageal biopsies per 2 cm BE or a ratio > or =2.0. Generalized estimating equation multivariable analysis was performed to assess factors associated with adherence, adjusted for clustering by individual gastroenterologist. RESULTS A total of 2245 BE surveillance cases were identified with linked endoscopy reports that recorded BE length and could be assessed for adherence. Adherence to guidelines was seen in 51.2% of cases. In multivariable analysis, longer segment BE was associated with significantly reduced adherence (3-5 cm, odds ratio [OR] 0.14, 95% confidence interval [CI] 0.10-0.19; 6-8 cm, OR 0.06, 95% CI 0.03-0.09; > or =9 cm, OR 0.03, 95% CI 0.01-0.07). Stratified by BE length, nonadherence was associated with significantly decreased dysplasia detection (summary OR 0.53, 95% CI 0.35-0.82). CONCLUSIONS Adherence to BE biopsy guidelines in the community is low, and nonadherence is associated with significantly decreased dysplasia detection. Future studies should identify factors underlying nonadherence as well as mechanisms to increase adherence to guidelines to improve early detection of dysplasia.

Abstract
OBJECTIVE In the USA, detection of intestinal metaplasia is a requirement for enrollment in surveillance programmes for dysplasia or adenocarcinoma in columnar-lined oesophagus. In the UK, it is believed that failure to detect intestinal metaplasia at index endoscopy does not imply its absence within the columnarized segment or that the tissue is not at risk of neoplastic transformation. The aim of this study was to investigate the factors predicting the probability of detection of intestinal metaplasia in the columnarized segment. MATERIAL AND METHODS Demonstration of intestinal metaplasia was analysed in 3568 biopsies of non-dysplastic columnar-lined oesophagus from 1751 patients from 7 centres in the UK. Development of dysplasia and adenocarcinoma was analysed in 322 patients without intestinal metaplasia and compared with that in 612 patients with intestinal metaplasia. RESULTS Intestinal metaplasia was more commonly detected in males than in females (odds ratio 1.244), longer segment length (10.3% increase per centimetre) and increasing number of biopsies taken (24% increase per unit increase). After 5 years of follow-up, 54.8% of patients without intestinal metaplasia at index endoscopy demonstrated intestinal metaplasia, and 90.8% after 10 years. There was no significant difference in the rate of development of dysplasia or adenocarcinoma between patients with or without intestinal metaplasia detection at index endoscopy. CONCLUSIONS Detection of intestinal metaplasia is subject to significant sampling error. It increases with segment length and number of biopsies taken. In the majority of patients, if sufficient biopsies are taken over time, intestinal metaplasia will be demonstrated. The decision to offer surveillance should not be based upon the presence or absence of intestinal metaplasia at index endoscopy as the risk of dysplasia and adenocarcinoma is similar in both groups.

Abstract
OBJECTIVES To assess the variation in practice of Barrett's esophagus (BE) management in comparison with accepted international guidelines before and after the introduction of a large BE randomized controlled trial (RCT) with protocols including those of tissue sampling. DESIGN A validated anonymized questionnaire was sent to 401 senior attending gastroenterologists asking for details of their current management of BE, especially histological sampling. Of the 228 respondents, 57 individuals (each from a different center) were in the first group to enter the ASPirin Esomeprazole (BE) Chemoprevention Trial (AspECT), and we assessed change in practice in these centers. RESULTS Ninety percent of specialists did not take adequate biopsies for histological diagnosis. Furthermore, 74% would consider aggressive surgical resection for prevalent cases of high-grade dysplasia in BE as their first-line choice despite the associated perioperative mortality. Ninety-two percent claim their lack of adherence to guidelines is because there is a need for stronger evidence for surveillance and medical interventions. Effect of the AspECT trial: Those clinicians in centers where the AspECT trial has started have improved adherence to ACG guidelines compared with their previous practice (P < 0.05). BE patients now get 18.8% more biopsies compared with previous practice, and 37.7% if the patient is entered into the AspECT trial (P < 0.01). CONCLUSIONS This large study indicates both wide variation in practice and poor compliance with guidelines. Because optimal histology is arguably the most important facet of BE management, the improvement in practice in centers taking part in the AspECT trial indicates an additional value of large international RCTs.

Abstract
OBJECTIVES Lifestyle and demographic risk factors for the development of oesophageal adenocarcinoma developing from columnar-lined oesophagus are not well defined. METHODS Demographic and lifestyle factors, endoscopy and histology reports were extracted from 1,761 subjects from seven UK centres. The associations of columnar-lined oesophagus with demographic and lifestyle factors and the development of adenocarcinoma were examined. RESULTS 5.5% of patients had prevalent adenocarcinoma (more common in males, older patients, patients diagnosed earlier in the cohort and current or recent smokers). Adenocarcinoma incidence was 23 patients in 3,912 years or 0.59% per annum. Only increased age at diagnosis correlated with an increased risk of incident adenocarcinoma. There was no association with obesity or alcohol history. CONCLUSIONS Oesophageal adenocarcinoma occurs more commonly in older patients and is more frequent in males than females. Once columnar-lined oesophagus had been diagnosed, there were no other demographic or lifestyle factors which were predictive of the development of incident adenocarcinoma in this cohort.

Abstract
AIMS To compare detection of Barrett's dysplasia and adenocarcinoma by systematic versus nonsystematic surveillance biopsy protocols. METHODS Upper GI consultation and open-access endoscopy are provided jointly at Glasgow Royal Infirmary by medical and surgical teams. The surgical team adopted annual systematic four-quadrant biopsy Barrett's surveillance in 1995. The medical team continued annual Barrett's surveillance with nonsystematic biopsy until 2004. We compare detection of Barrett's dysplasia and esophageal adenocarcinoma in unselected patients by these two biopsy strategies over 10 yr. All patients had > or = 3 cm Barrett's esophagus and histological proof of intestinal metaplasia. Patients referred for dysplasia management or with prevalent adenocarcinoma were excluded. Cohort A (N = 180) had four-quadrant biopsy every 2 cm while cohort B (N = 182) had nonsystematic biopsies. RESULTS Cohort A versus cohort B: Median number of biopsies per endoscopy: 16 versus 4. Prevalence of low-grade dysplasia (per patient): 18.9% versus 1.6% (P << 0.001). Prevalence of high-grade dysplasia: 2.8% versus 0% (P = 0.03). Incidence of low-grade dysplasia: 2.2% versus 6.6% (NS). Incidence of high-grade dysplasia: 2.8% versus 0% (P = 0.03). Nine cohort A patients (total 5%, 1.4% per patient-year) were treated for HGD (eight endoscopically, one by esophagectomy). Two had intramucosal adenocarcinoma. No cohort A patient developed advanced cancer but three cohort B patients developed and died of invasive Barrett's adenocarcinoma (0.6% per patient-year). CONCLUSIONS Patient age, gender, Barrett's segment length, and follow-up were similar (though not identical) in both cohorts, but confounding seems unlikely to account for a 13-fold difference in detection of prevalent dysplasia between the two groups. Our data support the hypothesis that systematic four-quadrant biopsy is considerably more effective than nonsystematic biopsy sampling in detecting Barrett's dysplasia and early adenocarcinoma. Greater biopsy numbers and the systematic pattern of biopsy taking may both contribute to this greater effectiveness.

Abstract
CONTEXT Identification of intestinal-type goblet cells (ITGCs) in hematoxylin-eosin-stained sections of esophageal biopsies is essential for the diagnosis of Barrett metaplasia. However, we have seen cases diagnosed as Barrett metaplasia based solely on cells that pose morphologic similarity to ITGCs on hematoxylin-eosin staining or stain positive with Alcian blue. OBJECTIVE To determine the clinical significance of goblet cell mimickers. DESIGN Initial biopsies from 78 patients with original diagnosis of Barrett metaplasia negative for dysplasia and a mean follow-up of 72 months were reviewed and reclassified into 3 categories: (1) ITGCs, (2) goblet cell mimickers, or (3) neither. Sections from available paraffin blocks were stained with Alcian blue at pH 2.5. The presence of the different types of cells and positive Alcian blue staining were correlated with each other and evaluated for their significance as predictors of progression to dysplasia. RESULTS Goblet cell mimickers were present in 35 cases and were associated with ITGCs in the same biopsy in 23 (66%) of these cases. Intestinal-type goblet cells were present in 56 cases, and the remaining 10 cases, although called Barrett on the original report, did not show either ITGCs or goblet cell mimickers. Only the presence of ITGCs was associated with significant risk for dysplasia (P = .008). Positive Alcian blue staining was not associated with a significant risk for dysplasia. CONCLUSIONS Our results indicate that the diagnosis of Barrett metaplasia should be rendered with confidence only when ITGCs are identified on routine hematoxylin-eosin-stained sections.

Abstract
BACKGROUND In August 2004, the United Kingdom Department of Health advisory body published dyspepsia referral guidelines for primary care practitioners. These guidelines advised empiric treatment with antisecretory medications and referral for endoscopy only in the presence of alarm symptoms. The current study aimed to evaluate the effect of these guidelines on the detection of esophagogastric cancer. METHODS The study reviewed a prospectively compiled database of 4,018 subjects who underwent open access gastroscopy during the years 1990 to 1998. The main outcome measures for the study were cancer detection rates, International Union Against Cancer (UICC) stage, and survival. RESULTS Gastroscopy identified esophagogastric carcinoma in 123 (3%) of the 4,018 subjects. Of these 123 patients, 104 (85%) with esophagogastric cancer had "alarm" symptoms (anemia, mass, dysphagia, weight loss, vomiting) and would have satisfied the referral criteria. The remaining 15% would not have been referred for initial endoscopic assessment because their symptoms were those of uncomplicated "benign" dyspepsia. The patients with "alarm" symptoms had a significantly more advanced tumor stage (metastatic disease in 47% vs 11%; p < 0.001), were less likely to undergo surgical resection (50% vs 95%; p < 0.001), and had a poorer survival (median, 11 vs 39 months; p = 0.01) than their counterparts without such symptoms. CONCLUSIONS The use of alarm symptoms to select dyspeptics for endoscopy identifies patients with advanced and usually incurable esophagogastric cancer. Patients with early curable cancers often have only dyspeptic symptoms, and their diagnosis will be delayed until the symptoms of advanced cancer develop.

Abstract
BACKGROUND Identification of high-grade dysplasia (HGD) in Barrett's esophagus has been considered an indication for esophagectomy because of the high risk for coexisting cancer. However, rigorous endoscopic surveillance programs recently have been recommended, reserving esophagectomy for patients whose cancer is identified on biopsy. This approach risks continued surveillance for patients who already have cancer unless reliable markers for the presence of occult cancer are identified. This study aimed to determine the endoscopic, histologic, and demographic features associated with the presence of occult cancer in patients with HGD. METHODS Endoscopic, histologic, and demographic findings for 31 patients who underwent esophagectomy for HGD were reviewed. The presence of an ulcer, nodule, stricture, or raised area on preoperative endoscopy was noted. The results of endoscopic biopsies taken before resection every 1 to 2 cm along the Barrett's segment were reviewed. The HGD was categorized as unilevel if the dysplasia was limited to one level of biopsy and as multilevel if more than one level was involved. Patients were divided into two groups according to the presence or absence of cancer in the resected specimens, and these variables were compared. RESULTS The prevalence of coexisting cancer in patients with HGD was 45% (14/31). Of the 31 patients in this study, 9 had a visible lesion. Cancer was found in the resected specimens from 7 (78%) of 9 patients with a visible lesion and 7 (32%) of 22 patients without a visible lesion (p = 0.019). Of 22 patients without a visible lesion, 10 had multilevel and 12 had unilevel HGD. The findings showed that 6 (60%) of 10 patients with multilevel HGD and 1 (8.3%) of 12 patients with unilevel HGD had cancer in the resected esophagus (p = 0.009). CONCLUSION For patients with HGD, a lesion visible on endoscopy and/or HGD at multiple biopsy levels is associated with an increased risk for coexisting cancer. These patients should be considered for early esophagectomy.

Abstract
Annually, approximately 13,200 people in the U.S. are diagnosed with esophageal cancer and 12,500 die of this malignancy. Of new cases, 9,900 occur in men and 3,300 occur in women. In part I of this two-part series, we explore the epidemiology, presentation and progression, work-up, and surgical approaches for esophageal cancer. In the 1960s, squamous cell cancers made up greater than 90% of all esophageal tumors. The incidence of esophageal adenocarcinomas has risen considerably over the past two decades, such that they are now more prevalent than squamous cell cancer in the western hemisphere. Despite advances in therapeutic modalities for this disease, half the patients are incurable at presentation, and overall survival after diagnosis is grim. Evolving knowledge regarding the etiology of esophageal carcinoma may lead to better preventive methods and treatment options for early stage superficial cancers of the esophagus. The use of endoscopic ultrasound and the developing role of positron emission tomography have led to better diagnostic accuracy in this disease. For years, the standard of care for esophageal cancer has been surgery; there are several variants of the surgical approach. We will discuss combined modality approaches in part II of this series.

Abstract
Esophagectomy remains the treatment of choice for the appropriate patient with Barrett's adenocarcinoma invading beyond the mucosa, without evidence of distant metastasis or invasion of adjacent organs. On the other hand, therapeutic management of patients with Barrett's high-grade dysplasia (HGD) or mucosal adenocarcinoma should be individualized, taking into account the patient's preferences, willingness to return for frequent endoscopic biopsies, and medical fitness to undergo esophagectomy. Surgery has to be considered the best treatment for HGD or superficial carcinoma, unless contraindicated by severe comorbidities, because it has proven to be the only treatment that is successful in curing the condition and preventing recurrent HGD or the development of invasive cancer. Nonsurgical treatment by photodynamic therapy or endoscopic mucosal resection may be a less invasive and organ-sparing option for elderly, poor-risk patients but it is still to be considered an investigational therapy that should only be conducted under a clinical trial protocol. Finally, intensive endoscopic biopsy surveillance of patients with HGD is another investigational option that may allow prompt treatment of cancer if it develops. However, few data document the safety of this observational approach.

Abstract
BACKGROUND To review our early operative results and endoscopic findings after laparoscopic fundoplication for Barrett's esophagus (BE). METHODS From January 1995 through December 2000, 49 patients with BE (35 men and 14 women) underwent laparoscopic antireflux surgery. Median age was 54 years (range, 28 to 85 years). No patient had high-grade dysplasia; 6, however, had low-grade dysplasia. All 49 patients had gastroesophageal reflux symptoms. Heartburn was present in 41 patients (84%), dysphagia in 16 (33%), epigastric or chest pain in 9 (18%), and other symptoms in 16 (33%). A Nissen fundoplication was performed in 48 patients and a partial posterior fundoplication in 1. Forty-one patients (84%) had concomitant hiatal hernia repair. RESULTS There were no deaths. Complications occurred in 2 patients (4%). Follow-up was complete in 48 patients (98%) and ranged from 1 to 81 months (median, 29 months). Functional results were classified as excellent in 33 patients (69%), good in 9 (19%), fair in 5 (10%), and poor in 1 (2%). Thirty-three patients (67%) underwent postoperative surveillance esophagoscopy with biopsy. Nine patients (18%) had total regression of BE and 3 (6%) had a decrease in total length. In the 6 patients with preoperative low-grade dysplasia, dysplasia was not found in 4, remained unchanged in 1, and progressed to in situ adenocarcinoma in 1. CONCLUSIONS Laparoscopic fundoplication is effective in controlling symptoms in the majority of patients with BE. While disappearance of BE may occur in some patients, the possibility of developing esophageal adenocarcinoma is not eliminated by laparoscopic fundoplication. Therefore, endoscopic surveillance should continue.

Abstract
Concern has been expressed about the rapid increase in the incidence of esophageal carcinoma in the United States. This rise is due to an increase in the number of cases of adenocarcinoma of the esophagus. Because of the relatively small number of cases of esophageal carcinoma, the absolute risk of developing this cancer in the United States remains small. Potential origins for this increase in esophageal adenocarcinoma are examined in this review, including the risk induced by obesity, low dietary antioxidants, high dietary fat, family history of breast cancer, smoking, gastroesophageal reflux, and Barrett's esophagus. The risk of esophageal adenocarcinoma is inversely associated with infection by Helicobacter pylori organisms. A better understanding of risk factors involved in the increased incidence of esophageal adenocarcinoma is important for development of new preventive strategies for this serious disorder.

Abstract
AIM: To reduce the incidence of postoperative anastomotic leak, stenosis, gastroesophageal reflux (GER) for patients with esophageal carcinoma, and to evaluate the conventional method of esophagectomy and esophagogastroplasty modified by a new three-layer-funnel-shaped (TLF) esophagogastric anastomotic suturing technique.
METHODS: From January 1997 to October 1999, patients with clinical stage I and II (IIa and IIb) esophageal carcinoma, which met the enrollment criteria, were surgically treated by the new method (Group A) and by conventional operation (Group B). All the patients were followed at least for 6 months. Postoperative outcomes and complications were recorded and compared with the conventional method in the same hospitals and with that reported previously by McLarty et al[7] in 1997 (Group C).
RESULTS: 58 cases with stage I and II (IIa and IIb) esophageal carcinoma, including 38 males and 20 females aged from 34 to 78 (mean age: 57), were surgically treated by the TLF anastomosis and 64 by conventional method in our hospitals from January 1997 to October 1999. The quality of swallowing was improved significantly (Wilcoxon W = 2142, P = 0.0001) 2 to 3 months after the new operation in Group A. Only one patient had a blind anastomatic fistula diagnosed by barium swallow test 2 months but healed up 3 weeks later. Postoperative complications occurred in 25 (43%) patients, anastomotic stenosis in 8 (14%), and GER in 13 (22%). The incidences of postoperative anastomotic leak, stenosis and GER were significantly decreased by the TLF anastomosis method compared with that of conventional methods (χ2 = 6.566, P = 0.038; χ2 = 10.214, P = 0.006; χ2 = 21.265, P = 0.000).
CONCLUSION: The new three-layer-funnel-shaped esophagogastric anastomosis (TLFEGA) has more advantages to reduce postoperative complications of anastomotic leak, stricture and GER.
