Prospective clinical cohort study: low incidence of Barrett esophagus but high rate of reflux disease at 5-year follow-up after sleeve gastrectomy versus Roux-en-Y gastric bypass. Surg Obes Relat Dis 2023; 19:707-715. [PMID: 36990881 DOI: 10.1016/j.soard.2023.02.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 11/10/2022] [Accepted: 02/04/2023] [Indexed: 03/02/2023]
Abstract
BACKGROUND Gastroesophageal reflux disease seems more frequent after laparoscopic sleeve gastrectomy (LSG) than Roux-en-Y gastric bypass (LRYGB). Retrospective case series have raised concerns about a high incidence of Barrett esophagus (BE) after LSG. OBJECTIVE This prospective clinical cohort study compared the incidence of BE ≥5 years after LSG and LRYGB. SETTING St. Clara Hospital, Basel, and University Hospital, Zürich, Switzerland. METHODS Patients were recruited from 2 bariatric centers where preoperative gastroscopy is standard practice and LRYGB is preferred for patients with preexisting gastroesophageal reflux disease. At follow-up ≥5 years after surgery, patients underwent gastroscopy with quadrantic biopsies from the squamocolumnar junction and metaplastic segment. Symptoms were assessed using validated questionnaires. Wireless pH measurement assessed esophageal acid exposure. RESULTS A total of 169 patients were included, with a median 7.0 ± 1.5 years after surgery. In the LSG group (n = 83), 3 patients had endoscopically and histologically confirmed de novo BE; in the LRYGB group (n = 86), there were 2 patients with BE, 1 de novo and 1 preexisting (de novo BE, 3.6% versus 1.2%; P = .362). At follow-up, reflux symptoms were reported more frequently by the LSG group than by the LRYGB group (51.9% versus 10.5%). Similarly, moderate-to-severe reflux esophagitis (Los Angeles grade B-D) was more common (27.7% versus 5.8%) despite greater use of proton pump inhibitors (49.4% versus 19.7%), and pathologic acid exposure was more frequent in patients who underwent LSG than in patients who underwent LRYGB. CONCLUSIONS After at least 5 years of follow-up, a higher incidence of reflux symptoms, reflux esophagitis, and pathologic esophageal acid exposure was found in patients who underwent LSG compared with patients who underwent LRYGB. However, the incidence of BE after LSG was low and not significantly different between the 2 groups.

Abstract
One of the most notable changes in the epidemiology of esophageal cancer (EC) is the rising incidence and prevalence of esophageal adenocarcinoma (EAC) in developed countries. The aim of this systematic review was to collect and summarize all the available evidence regarding lifestyle, diet, and EAC risk. We searched the PubMed and Scopus databases in January 2021 for studies providing information about lifestyle, diet, WCRF/AICR recommendations, and EAC risk; published in English; without a time filter. The Newcastle-Ottawa Scale was used to assess risk of bias. The results are stratified by risk factor. A total of 106 publications were included. Half of the case-control studies were judged as high quality, whilst practically all cohort studies were judged as high quality. Body mass index and waist circumference were associated with increased EAC risk. Physical activity did not appear to have a significant direct role in EAC risk. A diet rich in fruit, vegetables, and whole grains appeared to be more protective than a Western diet. Alcohol does not seem to be related to EAC, whereas smokers, particularly heavy smokers, have an increased risk of EAC. Prevention remains the best option to avert EAC. Comprehensible and easy to follow recommendations should be provided to all subjects. Protocol ID number: CRD-42021228762, no funds received.

Abstract
Background Data regarding barriers to Barrett’s esophagus (BE) surveillance is limited. Studying an urban center population, we aimed to characterize non-dysplastic BE surveillance rates and identify health, racial, and socioeconomic disparities affecting surveillance. Methods Patients with biopsy-confirmed BE were retrospectively identified between January 2002 and December 2012. Non-dysplastic BE patients were analyzed for adherence to established surveillance guidelines. Demographic, racial, comorbidities, and socioeconomic variables were extracted. Annual gross income (AGI) was utilized as a marker of socioeconomic status (SES). Univariate and multivariate analyses compared adherent vs. non-adherent patients to surveillance guidelines. Results A total of 217 patients with non-dysplastic BE were analyzed. The majority were male (67.3%) and Caucasian (75.6%), with only 47.5% adherent with the first surveillance endoscopy. Patients with a high average AGI were more likely to be adherent with the initial surveillance endoscopy than those with low AGI (p=0.032). Initial compliance with first surveillance was associated with better surveillance at regular intervals (p=0.001). No significant differences in age, primary language, insurance type, marital status, or Charlson Comorbidity Index (CCI) between adherent and non-adherent patients were found. Conclusions Although overall adherence to guidelines was suboptimal, this study identifies important socioeconomic disparities in the endoscopic surveillance for non-dysplastic BE. Identifying and understanding the barriers to care among these lower socioeconomic groups may ultimately lead to improved screening compliance and early BE detection.

Abstract
Background It is unknown why some cases of Barrett’s esophagus progress to invasive malignant disease rapidly while others do so more slowly or not at all. The aim of this study was to identify demographic and endoscopic factors that predict dysplastic and neoplastic progression in patients with Barrett’s esophagus. Methods Patients with Barrett’s esophagus who were assessed in 2000–2010 were assessed for inclusion in this retrospective study. Demographic and endoscopic variables were collected from an endoscopy database and the medical chart. Dysplastic and neoplastic progression was examined by time-to-event analysis. We used Cox proportional hazard regression modelling and generalized estimating equation methods to identify variables that were most predictive of neoplastic progression. Results A total of 518 patients had Barrett’s esophagus confirmed by endoscopy and pathology and at least 2 surveillance visits. Longer Barrett’s esophagus segment (≥ 3 cm) (odds ratio [OR] 1.2, 95% confidence interval [CI] 1.1–1.3) and increased age (≥ 60 yr) (OR 3.5, 95% CI 1.7–7.4) were independent predictors of progression from nondysplasia to dysplastic or neoplastic grades. Presence of mucosal irregularities (OR 8.6, 95% CI 2.4–30.4) and increased age (OR 5.1, 95% CI 1.6–16.6) were independent predictors of progression from nondysplasia to high-grade dysplasia or adenocarcinoma. Conclusion Increased age, longer Barrett’s segment and presence of mucosal irregularities were associated with increased risk of dysplastic and neoplastic progression. In addition to dysplasia, these factors may help stratify patients according to risk of neoplastic progression and be used to individualize surveillance. More prospective studies with larger samples are required to validate these results.

Abstract
PURPOSE OF REVIEW Barrett's esophagus (BE) is the only known measurable factor associated with esophageal adenocarcinoma. The development of endoscopic eradication therapy (EET) has transformed the way BE is managed. Given the fairly recent development of EET, its role in BE is still evolving. RECENT FINDINGS This paper discusses the challenges that endoscopists face at the preprocedural, intraprocedural, and postprocedural stages of BE management. These include challenges in risk stratification, dysplasia detection, ablation methods and dosimetry, choice of resection technique, and management of refractory disease. Despite the advances in EET in BE, there remain challenges that this review focuses on. Future research into these challenges will optimize ablation techniques and strategies in the future.

Abstract
AIM To clarify risk based upon segment length, diagnostic histological findings, patient age and year of surveillance, duration of surveillance and gender.
METHODS Patients registered with the United Kingdom Barrett’s Oesophagus Registry from 9 United Kingdom centers were included. The outcome measures were (1) development of all grades of dysplasia; (2) development of high-grade of dysplasia or adenocarcinoma; and (3) development of adenocarcinoma. Prevalent cases and subjects with < 1 year of follow-up were excluded. The covariates examined were segment length, previous biopsy findings, age at surveillance, duration of surveillance, year of surveillance and gender.
RESULTS One thousand and one hundred thirty six patients were included (total 6474 patient-years). Fifty-four patients developed adenocarcinoma (0.83% per annum), 70 developed high-grade dysplasia/adenocarcinoma (1.1% per annum) and 190 developed any grade of dysplasia (3.5% per annum). High grade dysplasia and adenocarcinoma increased with age and duration of surveillance. The risk of low-grade dysplasia development was not dependent on age at surveillance. Segment length and previous biopsy findings were also significant factors for development of dysplasia and adenocarcinoma.
CONCLUSION The risk of development of low-grade dysplasia is independent of age at surveillance, but high-grade dysplasia and adenocarcinoma were more commonly found at older age. Segment length and previous biopsy findings are also markers of risk. This study did not demonstrate stabilisation of the metaplastic segment with prolonged surveillance.

Abstract
INTRODUCTION We present the long-term outcome of Barrett's oesophagus (BO) at a District General Hospital set against the increasing numbers of patients with gastro-oesophageal reflux disease (GORD). METHODS Data were collected prospectively over 37 years. Comparison of GORD without Barrett's (NoBO) versus BO was performed from 1/1/1977 to 31/12/2001 when the NoBO database closed and outcomes of all cases of BO diagnosed until 31/12/2011 and followed up until 31/12/2013 have been reported. RESULTS During the period 1977-2001 the number of GORD NoBO cases was 11 610, and that of BO cases was 764 (6.2% of all GORD); total number of BO cases in 1977-2011 was 1468. NoBO patients were younger than BO patients: 52.2 versus 61.6 years. There was a male predominance in both groups: NoBO 55% and BO 62% (P<0.0001). The prevalence of oesophageal adenocarcinoma (OAC) was 87/1468 (5.9%) BO cases. Its incidence was 54/1381 (3.9%); the mean interval between the diagnosis of BO and incident OAC was 9 years (range 13 months-25.4 years); there was one OAC per 192 patient-years of follow-up (0.52% per year). Mortality was significantly lower in 37 patients under endoscopic surveillance at the time OAC was diagnosed (51 vs. 88% P=0.0141) partly because of older age and comorbidity of the other 17, in whom serial endoscopy was contraindicated. A proportional hazards model to allow for age estimated that the hazard rate ratio was lower in the surveillance group; however, this difference did not reach statistical significance (0.64, 95% confidence interval 0.30-1.48, P=0.08). Excluding prevalent cancers from both groups, mortality in BO was double that in NoBO (47 vs. 24%). CONCLUSION These 37 years of observation suggest, but do not confirm, that endoscopic surveillance may reduce the risk of death from OAC. Modern technology is likely to yield better results, but larger prospective studies are needed to confirm the benefits.

Abstract
Barrett's esophagus (BE), a common condition, is the only known precursor to esophageal adenocarcinoma (EAC). There is uncertainty about the best way to manage BE as most people with BE never develop EAC and most patients diagnosed with EAC have no preceding diagnosis of BE. Moreover, there have been recent advances in knowledge and practice about the management of BE and early EAC. To aid clinical decision making in this rapidly moving field, Cancer Council Australia convened an expert working party to identify pertinent clinical questions. The questions covered a wide range of topics including endoscopic and histological definitions of BE and early EAC; prevalence, incidence, natural history, and risk factors for BE; and methods for managing BE and early EAC. The latter considered modification of lifestyle factors; screening and surveillance strategies; and medical, endoscopic, and surgical interventions. To answer each question, the working party systematically reviewed the literature and developed a set of recommendations through consensus. Evidence underpinning each recommendation was rated according to quality and applicability.

Abstract
Purpose In the developed countries, the incidence of esophageal adenocarcinoma (EAC) is increasing over recent decades. The purpose of this meta-analysis was to arrive at quantitative conclusions about the contribution of alcohol intakes and the progression of Barrett's esophagus. Methods A comprehensive, systematic bibliographic search of medical literature published up to Oct 2013 was conducted to identify relevant studies. A meta-analysis was conducted for alcohol consumption on the Barrett's esophagus progression. Results A total of 882 cases in 6,867 individuals from 14 observational studies were indemnified in this meta-analysis. The result of this current meta-analysis, including 10 case-control and 4 cohort studies, indicated that alcohol consumption was not associated with the neoplastic progression in Barrett's esophagus (RR, 1.17; 95% CI, 0.93–1.48). When stratified by the study designs, no significant association was detected in either high vs low group or ever vs never group. Conclusions Alcohol drinking is not associated with risk of neoplastic progression in Barrett's esophagus. Further well designed studies are needed in this area.

Abstract
The incidence of esophageal adenocarcinoma has markedly increased in the last few decades and Barrett's esophagus is regarded as the precursor lesion of this cancer. The aim of the study was to quantify the adenocarcinoma risk associated with nonsteroidal anti-inflammatory drug use and to determine at which stage chemoprevention with this drug is the most effective in esophageal inflammation - Barrett's esophagus - adenocarcinoma sequence. A literature search was performed to identify studies published between 1998 and 2009 for relevant risk estimates. Fixed and random effect meta-analytical techniques were conducted for aspirin, nonaspirin nonsteroidal anti-inflammatory drugs, and all nonsteroidal anti-inflammatory drugs. Four cohort and 10 case-control studies were included. Use of aspirin and nonaspirin nonsteroidal anti-inflammatory drugs in normal population was associated with a reduced risk of adenocarcinoma (odds ratio [OR]: 0.73, 95% confidence interval [CI]: 0.65-0.83; OR: 0.84, 95% CI: 0.72-0.98, respectively). The use of all nonsteroidal anti-inflammatory drugs was associated with a reduced risk of adenocarcinoma (relative risk [RR]: 0.64, 95% CI: 0.42-0.96) in Barrett's esophagus patients. However, no obvious dose-effect relationships were found. In addition, we discovered a reverse association between drugs use and adenocarcinoma risk in people without a history of upper gastrointestinal tract disorders (OR: 0.57, 95% CI: 0.43-0.77, P= 0.12). Our meta-analyses suggest a protective effect of nonsteroidal anti-inflammatory drugs on the risk of adenocarcinoma. Our results also suggest that the drugs might act after the formation of Barrett's epithelium in the esophageal inflammation - Barrett's esophagus - adenocarcinoma sequence.

Abstract
BACKGROUND Barrett's esophagus (BE) is a premalignant lesion that predisposes to esophageal adenocarcinoma. However, the reported incidence of esophageal adenocarcinoma in patients with BE varies widely. We examined the risk of malignant progression in patients with BE using data from the Northern Ireland Barrett's esophagus Register (NIBR), one of the largest population-based registries of BE worldwide, which includes every adult diagnosed with BE in Northern Ireland between 1993 and 2005. SUBJECTS AND METHODS We followed 8522 patients with BE, defined as columnar lined epithelium of the esophagus with or without specialized intestinal metaplasia (SIM), until the end of 2008. Patients with incident adenocarcinomas of the esophagus or gastric cardia or with high-grade dysplasia of the esophagus were identified by matching the NIBR with the Northern Ireland Cancer Registry, and deaths were identified by matching with records from the Registrar General's Office. Incidence of cancer outcomes or high-grade dysplasia was calculated as events per 100 person-years (% per year) of follow-up, and Cox proportional hazard models were used to determine incidence by age, sex, length of BE segment, presence of SIM, macroscopic BE, or low-grade dysplasia. All P values were from two-sided tests. RESULTS After a mean of 7.0 years of follow-up, 79 patients were diagnosed with esophageal cancer, 16 with cancer of the gastric cardia, and 36 with high-grade dysplasia. In the entire cohort, incidence of esophageal or gastric cardia cancer or high-grade dysplasia combined was 0.22% per year (95% confidence interval [CI] = 0.19% to 0.26%). SIM was found in 46.0% of patients. In patients with SIM, the combined incidence was 0.38% per year (95% CI = 0.31 to 0.46%). The risk of cancer was statistically significantly elevated in patients with vs without SIM at index biopsy (0.38% per year vs 0.07% per year; hazard ratio [HR] = 3.54, 95% CI = 2.09 to 6.00, P < .001), in men compared with women (0.28% per year vs 0.13% per year; HR = 2.11, 95% CI = 1.41 to 3.16, P < .001), and in patients with low-grade dysplasia compared with no dysplasia (1.40% per year vs 0.17% per year; HR = 5.67, 95% CI = 3.77 to 8.53, P < .001). CONCLUSION We found the risk of malignant progression among patients with BE to be lower than previously reported, suggesting that currently recommended surveillance strategies may not be cost-effective.

Abstract
BACKGROUND Rates of distal and junctional adenocarcinomas are increasing in Western countries. METHODS Systematic review of epidemiological evidence linking obesity to esophageal adenocarcinoma (EA) was performed for studies published from 2005 to 2010. The current understanding of obesity's role in the etiology and potential dysplastic progression of Barrett's esophagus (BE) to EA is reviewed. RESULTS Accumulating epidemiological studies provide evidence of obesity's role as a driving force behind the increasing rates of EA. The simplest construct is that obesity promotes reflux, causing chronic inflammation and BE, predisposing to adenocarcinoma. However, as obesity is positively associated with the prevalence of many cancers, other mechanisms are important. A link may exist between fat distribution patterns and the risk of BE and EA. Altered metabolic profiles in the metabolic syndrome (MetS) may be a key factor in cell cycle/genetic abnormalities that mark the progression of BE towards cancer. Research highlighting a unique role of MetS in the length of BE, and its association with systemic inflammation and insulin resistance is discussed, as well as adipokine receptor expression in both BE and esophageal epithelium, and how MetS and the systemic response impacts on key regulators of inflammation and tumorigenesis. CONCLUSIONS/IMPACT: Obesity is positively associated with EA. The systemic inflammatory state consequent on the altered metabolism of obese patients, and the associated impact of adipocytokines and pro-coagulant factors released by adipocytes in central fat, may underlie obesity's relationship to this cancer. Novel therapeutic agents that may antagonize adipo-cytokines and potentially offer a promising role in cancer therapy are discussed.

Abstract
Esophageal adenocarcinoma is increasing in incidence. The main risk factor is the premalignant condition of Barrett's esophagus. There is great interest in chemoprevention to prevent or slow malignant transformation. There are many agents proposed as playing a role in chemoprevention; however, none is licensed for this role as yet. Aspirin possesses many favorable qualities for chemoprevention and is the focus of the largest randomized control trial in this field.

Abstract
BACKGROUND Barrett's esophagus (BE) is a precursor lesion of esophageal adenocarcinoma. Besides gastroesophageal reflux, possible risk factors for BE include overweight, cigarette smoking, and alcohol consumption. Our objective was to study these associations by using prospective data. METHODS The prospective Netherlands Cohort Study, initiated in 1986, consists of 120,852 men and women, aged 55 to 69 years at baseline. At baseline, all subjects completed a questionnaire on dietary habits and lifestyle. After 16.3 years of follow-up, 370 BE cases with specialized intestinal metaplasia and 3,866 subcohort members were available for case-cohort analysis. Cox proportional hazards models were used to calculate incidence rate ratios (RR) and 95% CIs. RESULTS Body mass index (BMI) at baseline was associated with risk of BE in women [multivariable adjusted RR per 1 kg/m(2), 1.07 (1.03-1.11)] but not in men [RR per 1 kg/m(2), 0.99 (0.93-1.05)]. The association in women was not specifically due to abdominal overweight. Former cigarette smokers were at increased risk of BE (RR = 1.33, 95% CI: 1.00-1.77), but current smokers were not. Smoking duration showed a positive association with BE risk (P(trend) = 0.03). For alcohol consumption, the RR per 10 g ethanol/d was 0.95 (0.87-1.03). CONCLUSIONS Increased BMI was a risk factor for BE in women but not in men. Several aspects of cigarette smoking were positively associated with BE risk. Alcohol consumption was not associated with an increased risk of BE. IMPACT Future research should focus on risk factors both for development and for progression of BE to esophageal adenocarcinoma.

Abstract
Barrett's metaplasia is discussed in the context of a general theory for the formation of metaplasias based on developmental biology. The phenotype of a particular tissue type becomes established during embryonic development by the expression of a specific set of transcription factors. If this combination becomes altered, then the tissue type can be altered. Such events may occur by mutation or by environmental effects on gene expression, normally within the stem cell population of the tissue. A macroscopic patch of metaplastic tissue will arise only if the new gene activity state is self-sustaining in the absence of its original causes, and if the new tissue type can outgrow the parent tissue type. An important candidate gene for the causation of Barrett's metaplasia is Cdx2 (Caudal-type homeobox 2). In normal development, this is expressed in the future intestine, but not the future foregut. Mouse knockout studies have shown that it is needed for intestinal development, and that its loss from adult intestine can lead to squamous transformations. It is also expressed in Barrett's metaplasia and can be activated in oesophageal cell cultures by treatment with bile acids. We have investigated the ability of Cdx2 to bring about intestinal transformations in oesophageal epithelium. Our results show that Cdx2 can activate a programme of intestinal gene expression when overexpressed in HET-1A cells, or in fetal epithelium, but not in the adult epithelium. This suggests that Cdx2, although necessary for formation of intestinal tissue, is not sufficient to provoke Barrett's metaplasia in adult life and that overexpression of additional transcription factors is necessary. In terms of diet and nutrition, there is a known association of Barrett's metaplasia with obesity. This may work through an increased risk of gastro-oesophageal reflux. Acid and bile are known to activate Cdx2 expression in oesophageal cells. It may also increase circulating levels of TNFalpha (tumour necrosis factor alpha), which activates Cdx2. In addition, there may be effects of diet on the composition of the bile.

Abstract
AIMS To examine the natural history of columnar-lined oesophagus with routinely diagnosed low-grade dysplasia and ascertain the risk of oesophageal adenocarcinoma development. METHODS AND RESULTS A multicentre retrospective cohort study of 283 patients with low-grade dysplasia. Follow-up data were obtained from examination of hospital records. One hundred and forty-four patients had biopsies prior to low-grade dysplasia diagnosis and 217 had follow-up biopsies after index low-grade dysplasia diagnosis. In these patients the incidence of high-grade dysplasia and adenocarcinoma combined was 4.6% per annum and of adenocarcinoma alone was 2.7% per annum. At most recent follow-up, 43 (19.8%) had persistent low-grade dysplasia, 37 (17.1%) had changes indefinite for dysplasia and 108 (49.8%) had non-dysplastic columnar-lined oesophagus. When prevalent cases were excluded (those occurring within 1 year of index low-grade dysplasia diagnosis), the annual incidence of high-grade dysplasia and adenocarcinoma combined was 2.2% and of adenocarcinoma alone was 1.4%. The relative risk for adenocarcinoma development in low-grade dysplasia compared with non-dysplastic columnar-lined oesophagus was 2.871 (P = 0.002). CONCLUSIONS Low-grade dysplasia has a threefold increased risk of progression to cancer compared with non-dysplastic epithelium, but in the majority of patients dysplasia is not subsequently detected.

Abstract
Barrett's columnar-lined oesophagus is the precursor lesion for oesophageal adenocarcinoma. The overall rate of progression to adenocarcinoma is 0.59% per annum. A large prospective multicentre trial is recruiting to assess the role of aspirin as a chemoprotective agent in prevention of development of cancer as well as cardiovascular protection in patients with Barrett's oesophagus. This retrospective analysis of the large UK National Barrett's Oesophagus Registry database seeks to analyse this question from within its large natural history study cohort. Multicentre UK retrospective cohort compared patients known to have been taking aspirin with those who did not take aspirin during the course of surveillance for columnar-lined oesophagus. End point was development of dysplasia or oesophageal adenocarcinoma. Analysis was undertaken using Cox's proportional hazard ratio. Total follow-up was 3683 patient-years. Eighty-six patients were taking aspirin, 650 were not taking aspirin (reference group). Numbers of patients developing all grades of dysplasia and adenocarcinoma were: 13 aspirin (15.1%) and 97 no aspirin (14.9%) (hazard ratio 0.723, 95% confidence interval 0.410-1.310, P = 0.294), high-grade dysplasia and adenocarcinoma: five aspirin (5.8%) and 25 no aspirin (3.8%) (hazard ratio 0.898, 95% confidence interval 0.340-2.368, P = 0.827) and adenocarcinoma: four aspirin (4.7%) and 16 no aspirin (2.5%) (hazard ratio 1.092, 95% confidence interval 0.358-3.335, P = 0.877). No significant difference was observed in hazard of developing dysplasia or adenocarcinoma between patients taking aspirin and those not taking aspirin during the course of follow-up of surveillance for columnar-lined oesophagus. In conclusion, no difference in risk of development of dysplasia or adenocarcinoma was observed between patients taking aspirin and those not taking aspirin in this large cohort.

Abstract
OBJECTIVES Endoscopic surveillance of patients with columnar-lined oesophagus (CLO) may identify those with early adenocarcinoma (AC). The benefits of surveillance are unproven and there is little evidence to support recommendations for precise endoscopic intervals. We sought to examine surveillance practice for CLO in the UK and the impact of endoscopic intervals on detection of dysplastic disease. METHODS Eight hundred and seventeen patients with CLO, registered with the UK National Barrett's Oesophagus registry and undergoing surveillance were studied. Endoscopic intervals were calculated and frequency of detection of dysplastic disease analysed using chi2 test of association. Factors affecting surveillance intervals were analysed using multiple linear regression. RESULTS 94.7% of patients with low-grade dysplasia (LGD), 95.0% with high-grade dysplasia (HGD) and 71.4% with AC were diagnosed on surveillance endoscopies. Mean endoscopic surveillance intervals varied between the centres from 1.07 to 1.63 years for nondysplastic CLO; 0.69-1.19 years for LGD, and 0.35-1.17 years for HGD; with overall mean surveillance intervals of 1.29, 1.01 and 0.44 years, respectively. When LGD was surveyed, significantly higher proportions of HGD/AC were detected at intervals of 3 months or less (P=0.013). Shorter endoscopic intervals were significantly associated with the presence of oesophageal strictures (P=0.002), ulcers (P=0.046), increasing patient age (P<0.001) and higher grade of dysplasia surveyed (P<0.001). CONCLUSION A variation in surveillance practice for CLO was observed throughout the UK. A large proportion of dysplastic disease is detected on specific surveillance endoscopies. Shorter endoscopic intervals for surveillance of LGD are associated with an increased detection of HGD/AC.

Abstract
BACKGROUND Prolonged gastro-oesophageal reflux resulting in columnar metaplasia of the oesophagus is the main risk factor for oesophageal adenocarcinoma. AIM To examine the duration of symptoms and associations of different symptoms with the development of columnar-lined oesophagus, dysplasia and adenocarcinoma. METHODS UK multicentre cohort study of patients with columnar-lined oesophagus whose date of symptom onset (1082 patients) and/or types of symptoms reported (1681 patients) were documented. Follow-up was examined by analysis of histological reports from the registering centers. RESULTS Symptoms of dysphagia/odynophagia and nausea/vomiting were associated with development of dysplasia. High-grade dysplasia and adenocarcinoma were associated with dysphagia/odynophagia and weight loss. Median duration from symptom onset to detection of columnar-lined oesophagus without intestinal metaplasia: 2.6 years, columnar-lined oesophagus with intestinal metaplasia: 5.0 years, indefinite changes for dysplasia: 19.3 years and low-grade dysplasia: 30.0 years. One tenth of patients had developed high-grade dysplasia at 9.6 years and one tenth had developed adenocarcinoma at 13.8 years from symptom onset. CONCLUSIONS In patients with columnar-lined oesophagus, symptoms of dysphagia/odynophagia and nausea/vomiting were associated with a higher risk of development of dysplasia and adenocarcinoma. There is a trend for longer duration of symptoms to the detection of dysplasia.

Abstract
Esophageal adenocarcinoma and its precursor Barrett's esophagus are increasing in incidence in western populations. Gastroesophageal reflux and high body mass index (BMI) are known risk factors. Studies about Barrett's esophagus in obese patients have emphasised the role of central adiposity as a stronger risk factor than BMI in the development of specialized intestinal metaplasia and subsequently esophagus adenocarcinoma. The proinflammatory impact of adipocytokines of the abdominal fat associated with the metabolic syndrome is also relevant. Except cardiovascular diseases, type 2 diabetes and non alcoholic steatohepatitis, abdominal obesity and metabolic syndrome are responsible of an increase of prevalence of esophageal adenocarcinoma, but also other cancer sites. In this review, we study the up to date main epidemiologic and physiopathologic data concerning this association that could be important in future for a preventive action in obese patients, especially when metabolic syndrome is present.

Abstract
Barrett's esophagus (BE) is a precursor for esophageal adenocarcinoma, which has an increased incidence rate over the last few decades. Its importance stems from the poor five-year survival of esophageal adenocarcinoma and current data that suggest a survival benefit when surveillance programs are implemented. In this review, we will cover the pathophysiology and natural history of BE and the different endoscopic findings. The prevalence of BE in different geographic areas and the incidence of high-grade dysplasia and adenocarcinoma in this patient population is reviewed. Recent recommendation for screening and surveillance of BE has been covered in this review as well as the efficacy of nonconventional imaging modalities and endoscopic ablation therapies.

Abstract
BACKGROUND Evidence regarding the association between alcohol consumption and the gastro-esophageal reflux disease (GERD) spectrum has been conflicting. We examined the association between alcohol consumption and erosive esophagitis and Barrett's epithelium in Japanese men. METHODS The study population comprised 463 men subjects who had undergone an upper endoscopy at the Gastroenterology Division of Yokohama City University Hospital between August 2005 and July 2006. The presence of erosive esophagitis and Barrett's epithelium was diagnosed based on the Los Angeles Classification and the Prague C and M Criteria, respectively. We divided the study population into four groups: never drinkers, light drinkers (less than 25.0 g of ethanol per day), moderate drinkers (25.0 to 50.0 g of ethanol per day), and heavy drinkers (more than 50.0 g of ethanol per day). A linear regression of the logistic regression analysis was used to analyze the dose-response trends. RESULTS Compared with never drinkers, light drinkers (less than 25.0 g ethanol per day), moderate drinkers (25.0 to 50.0 g per day), and heavy drinkers (more than 50.0 g per day) had ORs for erosive esophagitis of 1.110 (95% CI: 0.553 - 2.228, p = 0.7688), 1.880 (95% CI: 1.015 - 3.484, p = 0.0445) and 1.988 (95% CI: 1.120 - 3.534, p = 0.0190), respectively. These groups had ORs for Barrett's epithelium of 1.278 (95% CI: 0.752 - 2.170, p = 0.3643), 1.458 (95% CI: 0.873 - 2.433, p = 0.1500), and 1.912 (95% CI: 1.185 - 3.086, p = 0.0079), respectively. The odds ratios/grams (alcohol)/day of dose response trends for erosive esophagitis and Barrett's epithelium were 1.015 (95% CI: 1.004-1.026, p = 0.0066) and 1.012 (95% CI: 1.003-1.021, p = 0.0079), respectively. CONCLUSION These findings suggest that alcohol consumption in Japanese men tends to be associated with an increased risk of erosive esophagitis and Barrett's epithelium.

Abstract
Columnar metaplasia is the precursor lesion for esophageal adenocarcinoma, resulting from prolonged gastroesophageal reflux. The influence of the efficacy of reflux control on the development of neoplastic change in columnar-lined esophagus is not established. This study compares the rate of development of dysplasia and adenocarcinoma in patients with columnar metaplasia of the esophagus between patients treated pharmacologically and those treated with antireflux surgery. This study is a retrospective review of a cohort of patients enrolled in a multicenter national registry involving 738 patients from seven UK centers. Forty-one were treated with antireflux surgery, 42 with H2 receptor antagonist, 532 with proton pump inhibitor, and 114 with a combination of these medications. Nine had none of these medications or surgery. Total follow-up was 3697 years. Mean age and follow-up for patients treated medically were 61.6 and 4.96 years and surgically were 50.5 and 6.19 years, respectively. No patient in the surgical group developed high-grade dysplasia (HGD) or adenocarcinoma. Twenty patients treated medically developed adenocarcinoma and 10 developed HGD. Hazards ratio comparing pharmacological to surgical therapy for development of all grades of dysplasia and adenocarcinoma 1.77 (P = 0.272). Log rank test comparing antireflux surgery to pharmacological therapy for development of HGD or adenocarcinoma P = 0.1287 and for adenocarcinoma P = 0.2125. Although there was a trend towards greater efficacy of antireflux surgery over pharmacological therapy in reducing the development of dysplasia and adenocarcinoma, this did not reach statistical significance.

Abstract
RACIONAL: O esôfago de Barrett é complicação do refluxo gastroesofágico e predispõe ao surgimento do adenocarcinoma, sendo que vários fatores têm sido relacionados à sua etiopatogenia. OBJETIVO: Analisar o modelo experimental de refluxo duodenogastroesofágico e a ingestão de solução de nitrito de sódio na gênese do adenocarcinoma associado ao esôfago de Barrett. MÉTODOS: Sessenta ratos machos Wistar foram divididos em quatro grupos, com 20 animais controles não operados (10 animais ingeriram somente água e 10 água mais solução de nitrito de sódio) e 40 animais submetidos à anastomose duodenogastroesofágica látero-lateral (20 animais ingeriram somente água e 20 animais ingeriram água mais solução de nitrito de sódio). A ocorrência de esofagite, metaplasia, displasia, esôfago de Barrett e adenocarcinoma associado foram analisados. A classificação de Viena para displasia e adenocarcinoma foi empregada na análise dos resultados. RESULTADOS: Após 42 semanas de observação, nos animais operados sem ingestão de nitritos o esôfago de Barrett foi registrado em 26,3% (5/19), enquanto no grupo operado associado à ingestão de nitritos, foi encontrado em 72,3% (13/18) dos animais, sendo que neste grupo também foi encontrado seis adenocarcinomas (33,3%). Nenhum animal não operado apresentou o esôfago de Barrett. As categorias 2, 3 e 5 da classificação de Viena somente foram encontradas nos animais operados que ingeriram nitrito de sódio (66,7%). CONCLUSÃO: A ingestão de nitrito de sódio associado ao refluxo duodenogastroesofágico têm importante participação na gênese do adenocarcinoma associado ao esôfago de Barrett.
