Abstract
BACKGROUND Determining the prevalence of Barrett's esophagus is important for defining screening strategies. We aimed to synthesize the available data, determine Barrett's esophagus prevalence, and assess variability. METHODS Three databases were searched. Subgroup, sensitivity, and meta-regression analyses were conducted and pooled prevalence was computed. RESULTS Of 3510 studies, 103 were included. In the general population, we estimated a prevalence for endoscopic suspicion of Barrett's esophagus of (a) any length with histologic confirmation of intestinal metaplasia as 0.96% (95% confidence interval: 0.85-1.07), (b) ≥1 cm of length with histologic confirmation of intestinal metaplasia as 0.96% (95% confidence interval: 0.75-1.18) and (c) for any length with histologic confirmation of columnar metaplasia as 3.89% (95% confidence interval: 2.25-5.54) . By excluding studies with high-risk of bias, the prevalence decreased to: (a) 0.70% (95% confidence interval: 0.61-0.79) and (b) 0.82% (95% confidence interval: 0.63-1.01). In gastroesophageal reflux disease patients, we estimated the prevalence with afore-mentioned criteria to be: (a) 7.21% (95% confidence interval: 5.61-8.81) (b) 6.72% (95% confidence interval: 3.61-9.83) and (c) 7.80% (95% confidence interval: 4.26-11.34). The Barrett's esophagus prevalence was significantly influenced by time period, region, Barrett's esophagus definition, Seattle protocol, and study design. There was a significant gradient East-West and North-South. There were minimal to no data available for several countries. Moreover, there was significant heterogeneity between studies. CONCLUSION There is a need to reassess the true prevalence of Barrett's esophagus using the current guidelines in most regions. Having knowledge about the precise Barrett's esophagus prevalence, diverse attitudes from educational to screening programs could be taken.

[PMID: 31227185 DOI: 10.1016/j.surg.2019.04.024] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Revised: 04/01/2019] [Accepted: 04/23/2019] [Indexed: 01/11/2023]
Abstract
INTRODUCTION Laparoscopic Nissen fundoplication is the preferred operative treatment for patients with gastroesophageal reflux disease. The most recent published results only refer to clinical evaluations and few discuss objective measurements. Our purpose was to determine the late results of laparoscopic Nissen fundoplication, performing clinical, endoscopic, histologic, and functional studies. MATERIAL AND METHODS A total of 179 patients were included in a prospective study. All had gastroesophageal reflux disease symptoms of at least 5-year duration, daily dependence on proton pump inhibitors, and a type I hiatal hernia less than 5 cm. Exclusion criteria included Barrett's esophagus, hiatal hernia >5 cm, failed antireflux surgery, and obesity (body mass index >30). We performed a radiologic study, 3 or more endoscopic procedures with biopsy samples of the antrum and esophagogastric junction, esophageal manometry, and 24-hour pH monitoring. RESULTS We found that 4 patients (2.2%) died 3-4 years after operation from nonoperatiove reasons. A total of 25 patients (14%) were lost to follow-up, and 150 patients (83.8%) submitted to late objective evaluations (15 years). Visick I-II symptoms were observed in 79.3% and III-IV (failures) in 20.7%. Endoscopy showed a normal positioning of the esophagogastric junction in the Visick I-II patients and a type III cardia or hiatal hernia with erosive esophagitis in Visick III-IV patients. Short-segment Barrett's esophagus developed in 5.3% of patients. Lower esophageal sphincter pressure remained increased over the preoperative value in all groups. The 24-hour pH monitoring also was decreased over the preoperative value in Visick I-II patients but showed no significant change in Visick III-IV patients. Carditis at the esophagogastric junction regressed to fundic mucosa in 50% of Visick I-II patients. CONCLUSION Laparoscopic Nissen fundoplication produces control of symptoms in 80% of patients late (up to 15 years) after surgeries corroborated by endoscopic, histologic examinations, and functional studies. It is essential to perform these objective evaluations to demonstrate the "antireflux effect" after laparoscopic Nissen fundoplication.

Abstract
AIM Our main objectives were to evaluate the influence of two-year proton pump inhibitors (PPI) therapy in patients with Barrett's oesophagus on its length, in both types, short and long segment. METHODS In this single-centre, prospective interventional controlled study were analysed data collected prospectively over two years from patients with Barrett's oesophagus diagnosed by endoscopy. Patients who received continuous proton pump inhibitors (PPI) for 2 years were included. At each patient visit symptoms were recorded, and at each endoscopy, the length of Barrett's oesophagus (BE) was measured. Biopsies were taken along the length of the oesophagus at intervals of 1 cm. In total, 50 patients with Barrett's oesophagus were included in the study: 10 of whom had long-segment Barrett's oesophagus, and 40 patients had short-segment Barrett's oesophagus. The mean number of endoscopies performed was 3 per patient. RESULTS The length of Barrett's esophagus (BE) was influenced by PPI therapy: Circumferential extension in BE patients short-segment Barrett's esophagus (SSBE) (before treatment was 1.5 cm and after treatment was 0.8 cm Maximum proximal extension in SSBE group before treatment was 2.3 cm (SD ± 1.1 cm), and 1.1 cm (SD ± 0.9 cm), respectively. Squamous islands were detected in 25% of patients examined after 2 years on PPIs. CONCLUSIONS PPIs achieve a reduction to the length of Barrett's oesophagus, in both types, and the development of squamous islands is commonly associated with their use.

Histologic Features Associated With Columnar-lined Esophagus in Distal Esophageal and Gastroesophageal Junction (GEJ) Biopsies From GERD Patients: A Community-based Population Study.

Abstract
There are inherent problems with the endoscopic and pathologic criteria for columnar-lined esophagus (CLE). Furthermore, the clinical and biological significance of an irregular squamocolumnar junction (SCJ) is unclear. The aim of this study was to evaluate the association between histologic features in SCJ biopsies and CLE and to gain insight into the significance of an irregular SCJ. The study was a cross-sectional analysis of 2176 mucosal biopsies of the SCJ from 544 patients in a large prospective community clinic-based study of gastroesophageal reflux disease in Washington State. Biopsy samples were evaluated blindly for a wide variety of histologic features, such as the presence and type of mucosal glands, submucosal glands and ducts, goblet cells, multilayered epithelium (ME), inflammation, and buried columnar epithelium. Histologic findings were correlated with the endoscopic findings (normal Z-line, irregular Z-line, or CLE) and evaluated by logistic regression and receiver operating characteristic analysis.Five histologic features were associated with CLE: pure mucous glands, ME, presence of goblet cells, ≥50% of crypts with goblet cells, and buried columnar epithelium. Pure oxyntic glands were inversely associated with CLE. The features most strongly related to CLE included biopsies with ≥50% of crypts with goblet cells, ME, and mucosal gland type (area under the curve=0.71; 95% confidence interval=0.66-0.76). Patients with an irregular Z-line were histologically similar to those with CLE. Certain histologic features in biopsies of the SCJ are associated with the presence of CLE. Irregularity of the Z-line is probably indicative of ultrashort segment CLE, instead of being a potential variation of normal.

Abstract
Background Gastroesophageal reflux disease (GERD) has become a major health problem globally, affecting patients’ health-related quality of life (HRQOL). Barrett’s esophagus (BE) is a precancerous lesion associated with GERD. BE patients might not only suffer from HRQOL losses by GERD but also face psychological distress due to the increased risk of developing cancer. However, the majority of patients in Asia have shorter BE segment which is different from the West. This study aimed to determine whether the HRQOL in BE patients were worse than in healthy referents in Taiwan. Methods Patients who received referral esophagogastroduodenoscopy for various symptoms were evaluated for the existence of BE. Lesions were judged as endoscopically suspected esophageal metaplasia (ESEM) if they showed morphological resemblances to BE by endoscopy. The diagnosis of BE was confirmed by histology with intestinal metaplasia or gastric metaplasia based on the Montreal definition. The World Health Organization Quality of Life (WHOQOL-BREF) was administered to BE patients before treatment. For each BE patient, we selected 2 age-, sex-, educational background and municipality-matched healthy referents, sampled by simple randomization method from a national survey in Taiwan. Multiple linear regression models were constructed to control the potential confounders. Results A total of 84 patients diagnosed with BE were enrolled as BE group and then compared with 168 healthy referents. The BE group had significantly lower WHOQOL-BREF scores than those of healthy referents in the physical domain (P < 0.05) but higher scores in the environment domain (P < 0.05). In the physical domain, the BE group had significantly lower scores in various facets, including pain, discomfort, sleep and rest and dependence on medications or treatments. There was no significant difference in social and psychological domains between the BE group and healthy referents. Conclusions BE patients suffer from poor sleep and rest and high dependence on medications, which significantly reduce their quality of life. Individual facets of each domain warrants a better clinical healthcare to improve quality of life of BE patients.

Abstract
Pathological specimens from columnar-lined oesophagus (CLO) comprise a considerable proportion of the workload of gastrointestinal pathologists in Western countries. There remain controversies concerning the diagnostic role of pathology. More recently, in the UK at least, the diagnosis has been regarded as primarily an endoscopic endeavour, with pathology being corroborative and only diagnostic when endoscopic features are equivocal or when there are additional features that make the endoscopic diagnosis unclear. There is also recognition that demonstration of intestinalisation or 'goblet cells' is not paramount, and should not be required for the diagnosis. There have been notable changes in the management of CLO neoplasia: pathologists are centrally involved in its management. Pathological assessment of endoscopic mucosal resection (EMR) specimens provides the most useful means of determining the management of early neoplasia and of determining indications for surgery. This represents an extraordinarily rapid change in management, in that, <10 years ago, laborious Seattle-type biopsy protocols were recommended, and high grade dysplasia was an indication for resectional surgery. Now, individual patient management is paramount: multi-professional meetings determine management after biopsy and EMR assessment. One significant change is that major resections are undertaken less often, in Western countries, for CLO neoplasia.

Abstract
BACKGROUND To date, therapeutic guidelines and pattern of reflux for patients with no-dysplasia (ND) or low-grade dysplasia (LGD) Barrett's esophagus (BE) remain unclear. We aimed to analyze pattern of reflux and regression of ND- or LGD-BE after medical and surgical treatment. METHODS We studied a cohort of ND- and LGD-BE patients who underwent laparoscopic total fundoplication and a cohort of ND- and LGD-BE patients managed medically. Patients were matched for age, sex, and disease duration. After 1 year of follow-up at least, all patients underwent upper endoscopy with esophageal biopsies to evaluate any histological changes, as well as manometry and impedance-pH-metry to re-assess reflux patterns. RESULTS Thirty-seven patients (20 LGD, 17 ND) undergoing laparoscopic fundoplication were enrolled and compared with 25 patients (13 LGD, 12 ND) managed with proton pump inhibitors (PPI). Laparoscopic fundoplication resulted in a better control of both acidic and weakly acidic reflux (P < 0.001) and was associated with a higher probability of reversion for LGD (P < 0.01). Esophageal motility did not differ between surgically and medically treated patients. CONCLUSIONS In patients with ND- or LGD-BE, laparoscopic fundoplication seems to warrant a better control of all kinds of refluxate and it is associated with a higher likelihood of reversion of both LGD- and ND-BE, compared with PPI therapy.

Abstract
AIM: To determine the incidence and characteristics of endoscopically suspected esophageal metaplasia (ESEM) in a primary adult care institution.
METHODS: Eight hundred and thirty two consecutive individuals (mean age, 67.6 years) undergoing upper gastrointestinal endoscopy between January 2009 and December 2010 were included in this study. The diagnosis of ESEM was based on the criteria proposed by the Japan Esophageal Society, and was classified as long segment ESEM (3 cm or more) or short segment ESEM (< 3cm). Short segment ESEM was further divided into circumferential and partial types. Age, gender, hiatus hernia, esophagitis, gastroesophageal reflux disease (GERD)-suggested symptoms, and antacid medications were recorded as background factors. Esophagitis was graded according to the Los Angeles classification. Hiatus hernia was divided into absent and at least partially present.
RESULTS: Long and short segment ESEM were found in 0 and 184 (22.1%) patients, respectively (mean age of short segment ESEM patients, 68.3 years). Male gender and hiatus hernia were shown to be significant factors affecting short segment ESEM by both univariate (P = 0.03 and P = 9.9x10-18) and multivariate [Odds ratio (OR) = 1.45; P = 0.04, and OR = 43.3; P = 1.5x10-7)] analyses. Two thirds of patients with short segment ESEM did not have GERD-suggested symptoms. There was no correlation between short segment ESEM and GERD-suggested symptoms.
CONCLUSION: The incidence of short segment ESEM in our community practice seems higher than assumed in Asian countries. As GERD-suggested symptoms are a poor predictor of ESEM, endoscopists should bear in mind that silent short segment ESEM does exist and, in fact, was found in the majority of our patients.

Abstract
AIM To present a complex oral health status including salivary factors, microbial analysis and periodontal and hygiene indices in patients with active gastro-oesophageal reflux disease (GORD). Return of stomach contents is quite common in cases of gastro-oesophageal reflux. Pathological acid movement from the stomach into the oesophagus and oral cavity may lead to a development of dental erosion. Long-lasting untreated GORD may damage hard dental and periodontal tissues and alter the oral microbial environment. The quality and amount of the saliva play an important role in hard and soft oral tissues changes. METHOD Fifty patients with diagnosed GORD using 24-hour pH manometry underwent dental examination; 24 patients had active GORD and had been waiting for surgical therapy. In this patient group oral health status and salivary analysis were evaluated. RESULTS Indicated low salivary flow rates and buffering capacity with a low caries risk but a high risk for dental erosion progression.

Abstract
BACKGROUND Barrett's oesophagus is regarded as the most important risk factor for development of oesophageal adenocarcinoma. According to current guidelines, treatment should be limited to symptomatic Barrett's oesophagus. AIM To evaluate the expression of Ki67, cyclooxygenase-2 (COX-2) and apoptosis in Barrett's oesophagus after 12 months of double-dose proton pump inhibitor therapy. The effectiveness of esomeprazole and pantoprazole was also compared. METHODS Seventy-seven nondysplastic Barrett's oesophagus patients underwent baseline upper endoscopy. Patients were then randomised into two groups: one group was allocated to receive esomeprazole 40 mg b.d. and the other group pantoprazole 40 mg b.d. for 12 months. A follow-up endoscopy was performed at the end of treatment. Sixty-five of 77 patients agreed to undergo oesophageal manometry and 24-h pH-metry. Barrett's oesophagus biopsies, obtained at baseline and after treatment, were analysed using immunohistochemistry to assess Ki67 and COX-2 expression; apoptosis was evaluated using TUNEL. RESULTS In the esomeprazole group, a significant decrease in Ki67 and COX-2 expression, as well as an increase in apoptosis, were observed (P < 0.05). By contrast, in the pantoprazole group Ki67, COX-2 and apoptosis did not vary significantly from baseline. By 24-h oesophageal pH-monitoring, a normal acid exposure time was recorded in patients treated with esomeprazole, while those allocated to pantoprazole displayed abnormal acid exposure (P < 0.05). CONCLUSIONS Treatment of Barrett's oesophagus patients with high-dose esomeprazole, but not pantoprazole, promoted a decrease in proliferative markers, concomitantly with a decrease in apoptotic cell death. Moreover, esomeprazole allowed a better oesophageal acid control than pantoprazole.

Abstract
BACKGROUND/AIM Laparoscopic fundoplication can alter the natural course of Barrett's esophagus (BE). This study was undertaken to assess this role in patients with non-complicated BE. MATERIALS AND METHODS From October 2004 to October 2009, 43 patients with BE (32 men and 11 women) underwent laparoscopic Nissen fundoplication surgery in the Department of Surgery at Minia University Hospital. The median age of these patients was 46 years (range: 22-68 years). Patients with high-grade dysplasia, invasive cancer, or previous antireflux surgery were excluded. All 43 patients had gastroesophageal reflux symptoms. Heartburn was present in all patients, regurgitation in 41 (95.3%), dysphagia in 8 (18.6%), retrosternal pain in 30 (69.8%), upper gastrointestinal hemorrhage in 6 (13.9%), and respiratory symptoms in 19 (44.2%). Nissen fundoplication was performed in all patients. Thirty-four patients (79.1%) had concomitant hiatal hernia and nine patients (20.9%) had low-grade dysplasia. RESULTS The median follow-up period was 25.6 months. There was significant improvement of symptoms after surgery (P<0.05). Eight (18.6%) of those with short-segment BE had total regression and four (9.3%) of those with long-segment BE had a decrease in total length. Among the nine patients with preoperative low-grade dysplasia, dysplasia disappeared in seven, remained unchanged in one, and progressed to in situ adenocarcinoma in one patient. CONCLUSIONS laparoscopic fundoplication succeeded in controlling symptoms but had unpredictable effect on dysplasia and regression of BE. Laparoscopic fundoplication does not eliminate the risk of developing esophageal adenocarcinoma and therefore, endoscopic follow-up should be continued in these patients.

Abstract
Barrett's esophagus (BE) appears to be more common in Western than in Asian countries. BE is a complication of gastroesophageal reflux disease (GERD). Anatomical abnormalities of the esophagogastric junction (EGJ) are an important factor in the pathogenesis of GERD. We aimed to determine the prevalence of BE in Turkey, which is geographically located between Europe and Asia, and to investigate the frequency of BE according to the degree of anatomical disruption in the EGJ. This prospective study was performed on 1000 consecutive patients referred for endoscopy for any clinical indication. All patients underwent a structured interview that assessed major symptoms of GERD (regurgitation and heartburn). BE was diagnosed when specialized intestinal metaplasia was detected histologically in the esophageal biopsy specimens. Endoscopically assessed integrity of the EGJ was classified as one of three types, as follows: 1 Normal EGJ. The endoscope shaft was gripped tightly by the cardia in retroflexed endoscopy, or it was gripped less tightly but the cardia was seen to open and close with respiration. 2 Widened EGJ. The cardia was open during all phases of respiration in retroflexed endoscopy, but there was no endoscopic evidence of hiatal hernia (HH) on the antegrade view. 3 HH. The axial length from the EGJ to the diaphragmatic hiatus was at least 2 cm. BE was found in 12 patients (1.2%). Normal EGJ was seen in 90.7% of patients, widened EGJ in 4.3%, and HH in 5%. Patients with widened EGJ had a significantly higher incidence of major reflux symptoms and erosive esophagitis compared with those with normal EGJ (P= 0.001). BE was found in 14% of patients with HH and in 0.5% of patients with a normal EGJ (P= 0.001). None of the patients with widened EGJ had BE. In terms of BE frequency, these patients did not differ significantly from those with normal EGJ (P= 0.793) but did differ significantly from those with HH (P= 0.014). The prevalence of BE was 1.2% in a Turkish population undergoing endoscopy for any reason. In terms of EGJ integrity, comparison of the groups showed that even in the absence of HH, patients with widening of the EGJ had an increased prevalence of major reflux symptoms and erosive esophagitis. However, histologically confirmed BE was not seen among patients with widened EGJ.

Abstract
The incidence of Barrett's esophagus (BE) and esophageal adenocarcinoma has increased in Western countries in recent decades. The aim of this study is to describe the changes in incidence and prevalence of BE diagnosis, dysplasia, and adenocarcinoma development in BE patients in a South-European Mediterranean area. Retrospective population-based analyses of endoscopy and pathology reports from 1976 to 2001 was performed. Data from patients with diagnosis of BE and/or esophageal carcinoma were collected. The study period was divided in four quartiles for statistical calculations; parametric and nonparametric tests were used. A 6.9-fold increase was found in the diagnosis of long-segment BE from the first to the fourth quartile, and a 9.3-fold increase in short-segment BE from 1995 to 2000, in contrast to a much smaller increase of 1.9-fold increase in the number of upper gastrointestinal endoscopies. The adjusted incidence of BE diagnosis increased from 0.73 to 9.73 cases/100,000 (first to fourth quartile, respectively) and the adjusted prevalence from 6.51 to 76.04 cases/100,000 (1985-2001). The incidence of dysplasia was 2.13% per year (95% confidence interval: 0.05-11.3%) - 1.78% for low-grade dysplasia and 0.36% for high-grade dysplasia - giving a total incidence of 1 per 47 patient-years. The incidence of adenocarcinoma during follow-up was 0.48% per year (95% confidence interval: 0.006-2.62%), for an incidence of 1 per 210 patient-years. Nineteen patients with BE (14 long-segment BE, 5 short-segment BE) were diagnosed with esophageal adenocarcinoma, with eight being diagnosed during endoscopic surveillance. Only 14 (8%) adenocarcinoma patients diagnosed during the study period had a history of BE. BE diagnosis has dramatically increased over recent decades in our population, unrelated to an increase in endoscopies. Progression to low-grade dysplasia and adenocarcinoma is rare. Surveillance may have a low impact on the survival of adenocarcinoma patients in Southern Europe.

Abstract
BACKGROUND AND AIMS Recently, a Global definition and a classification of gastroesophageal reflux disease (GERD) were developed by Montreal Consensus Group, composed of international expert gastroenterologists. Guidelines and consensus documents are, however, infrequently accepted and adopted at a local level. The aim of this study was to measure the acceptance of Montreal Global definition of GERD consensus document by specialists in a single country (Italy) and to measure the linguistic, scientific, and practical differences between the international consensus document and the Italian version. METHODS A 2-day meeting was held in June 2007 in Rome, Italy, attended by 147 Italian physicians who were experts in gastroenterology. They reviewed the individual original statements in their Italian translation and then voted on the statement using the scoring system used by the Montreal Consensus Group (6-point Likert scale). Voting was performed at baseline and after an analytical discussion on each statement, led by six internationally renowned experts. Consensus was defined as an agreement with a statement by at least two-thirds of the group. Results were compared with the Montreal statements. RESULTS AND DISCUSSION The level of consensus was already extremely high at the first vote (>90% with the two-thirds threshold). The level of agreement at the second vote increased slightly. The maximum variation between two votes was 33% (of increase from first to second round, 59-92%). The high level of agreement could be because of both the general acceptance of Montreal Consensus by scientific community, and the new scientific evidences published after the Montreal report, which fit with the original statements. CONCLUSION This study is the first national linguistic validation of the Montreal Global definition of GERD and is also proof of its scientific validity, based on the same methodology used to create the Montreal statements. It also suggests that evidence-based International disease classification systems can be applied to local settings after validation by local experts.

Abstract
Our objective was to investigate the endoscopic and clinico-pathological characteristics in patients with Barrett's esophagus (BE) in China. Using the terms 'Barrett's esophagus' and 'Barrett's esophagus, China' as key words, literatures published in Chinese and English journals were searched in Chinese data banks, as well as PubMed and ISI Web of Science from 1989 to 2007. An analysis was carried out with the standard inclusion and exclusion criteria. A total of 4120 cases were included in this study. BE was found in 2.44% of patients undergoing endoscopy for various symptoms of upper gastrointestinal tract diseases; the male : female ratio was 2.09 : 1, the average age of detection of BE was 53.15 years old, and 51% of patients with BE had typical symptoms for gastroesophageal reflux disease (GERD). The island-type BE was predominant (56.80%), and the occurrence of BE with special intestinal metaplasia (SIM) was 36.58%, but SIM was more common in tongue-type BE than island-type and circumferential-type BE (both P < 0.001), as well as in long segment BE (LSBE) than in short segment BE (SSBE) (P < 0.001). A total of 46.39% of patients had Helicobacter pylori infection. The mean length of follow up was 2 years in 492 patients. The incidence of adenocarcinoma was 0.61% patient-years of total follow up. In China, the endoscopic prevalence of BE is lower, but the average age of diagnosis is younger; a high proportion of H. pylori infection is found in patients with BE, and about half of the patients have no typical symptoms of GERD; the tongue-type BE and the LSBE are apt to SIM.

Abstract
OBJECTIVES To investigate the prevalence of endoscopically suspected esophageal metaplasia (ESEM) in an ethnic Chinese population by endoscopic and pathologic evaluation and to assess the utility of Prague C and M criteria. METHODS Consecutive patients who received esophagogastroduodenoscopy either as a part of therapy for various upper abdominal symptoms or as an annual health check-up were evaluated for the existence of ESEM and Barrett's esophagus (BE). Biopsy with standardized random four pieces every 2 cm from the four quarters of esophagus with ESEM lesion was performed. BE was defined by histological verification of specialized intestinal metaplasia and gastric metaplasia and was categorized according to the Prague C and M criteria. RESULTS A total of 5,179 subjects were screened from Jan. 2007 to Dec. 2007. This study enrolled 4,797, including 3,386 for referral endoscopy and 1,411 for screening endoscopy. Prevalence of BE among the referral endoscopy, screening endoscopy, and overall was 1.06%, 0.35%, and 0.85%, respectively. A total of 41 subjects with BE were detected among 93 ESEM subjects. Short segment BE (75.6%, n=31) was more prevalent than long segment BE (24.4%, n=10). The proportions of BE from subjects with ESEM by Prague C and M criteria were C< or =1M1 38.9% (19/50), C< or =1M2 40% (12/30), and CxM> or =3 76.9% (10/13). CONCLUSIONS On the basis of the standardized protocol with random four-quadrate endoscopic biopsy, we have demonstrated the utility of Prague C and M criteria to characterize the BE in an ethnic Chinese population.

Abstract
BACKGROUND The prevalence of Barrett esophagus (BE) remains elusive in the general populations. GOALS The purpose of this study was to identify the prevalence and clinical characteristics of BE in a Chinese general population. STUDY Between June 2003 and December 2006, consecutive subjects were evaluated via upper gastrointestinal endoscopy during a routine health examination. Patients were evaluated for any abnormalities, including endoscopically suspected esophageal metaplasia (ESEM) and erosive esophagitis (EE). Biopsies were attained from patients with ESEM to confirm a diagnosis of BE. The demographic data and endoscopic findings were retrospectively analyzed. RESULTS Of the 19,812 endoscopies performed, 56 patients (0.28%) were diagnosed with ESEM and 3129 patients (15.7%) with EE. Twelve of the 56 patients diagnosed with ESEM (0.06% of the total number of patients who underwent endoscopy) were confirmed to have BE after histologic analysis of the biopsies. Patients with BE were older than patients without BE (61.6 vs. 51.7 y), and only one of the 12 patients diagnosed with BE (8.3%) reported typical gastroesophageal reflux symptoms. A majority of the BE patients were categorized as short-segment BE (91.7%) and concomitant EE was found in 4 (33.3%). Smoking, alcohol, and metabolic disorders seemed to be associated with the presence of BE and EE. CONCLUSIONS The prevalence of BE in a Chinese general population was lower than that in other reported studies, particularly in comparison with the studies originating from Western countries. Patients with advanced age and metabolic disorders are risk factors for developing BE.

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
BACKGROUND: Barrett’s esophagus, the major risk factor for esophageal adenocarcinoma, is detected in approximately 10%-14% of individuals submitted to upper endoscopy for the assessment of gastroesophageal reflux disease related symptoms. Prevalence studies of Barrett’s esophagus in individuals without typical symptoms of gastroesophageal reflux disease have reported rates ranging from 0.6% to 25%. AIM: To determine the prevalence of Barrett’s in a Brazilian population older than 50 years without typical symptoms of gastroesophageal reflux disease. METHODS: A total of 104 patients (51 men), mean age of 65 years, with an indication for upper endoscopy but without symptoms of heartburn and/or acid regurgitation (determined with a validated questionnaire) were recruited. Subjects submitted to upper endoscopic examination in the last 10 years or using antisecretory medication (proton pump inhibitors) during the last 6 months were not included. Methylene blue chromoscopy was performed during the endoscopic exam to facilitate identification of the metaplastic epithelium. RESULTS: Barrett’s esophagus was diagnosed endoscopically and confirmed by histology in four patients, all of them males. The metaplastic segment was short (less than 3 cm) and free of dysplasia in all patients. The prevalence of Barrett’s esophagus was 7.75% in the male population and 3.8% in the general population studied. CONCLUSION: Due to the low prevalence of Barrett’s esophagus found in the present study, associated with the finding of short-segment Barrett’s esophagus in all cases diagnosed and the absence of dysplasia in the material analyzed, endoscopic screening for Barrett’s esophagus in patients above the age of 50 without the classical symptoms of gastroesophageal reflux disease is not indicated for the Brazilian population.

Abstract
OBJECTIVES Barrett's mucosa is considered as a mosaic of three epithelial types but little is known about the topography of intestinal metaplasia in columnar lined esophagus. The aims of the study were to determine the prevalence of intestinal metaplasia within long and short segments of columnar lined esophagus and to analyze the distribution of the intestinal metaplasia within long segments of Barrett's esophagus. PATIENTS AND METHODS The study was performed on the initial endoscopy carried out among 112 patients enrolled in an endoscopic surveillance program. Seventy-two patients with columnar mucosa extending more than 3 cm into the esophagus (group I) and 40 patients with a short segment of columnar mucosa (group II) had multiple biopsies according to a standardized protocol. 1163 biopsies were analyzed on the whole: 949 biopsies in group I and 214 biopsies in group II. RESULTS Intestinal metaplasia was identified among 650 (68.5%) and 50 (23.4%) biopsies in groups I and II respectively (P<10-7). The proportion of biopsies with foci of intestinal metaplasia increased significantly with the length of the columnar mucosa. The diagnosis of Barrett's esophagus was confirmed in 100% of the patients in group I and in 45% of the patients in group II. In long segments of Barrett's esophagus, intestinal metaplasia was more frequently observed in the 2 upper thirds of the columnar mucosa that in the lower third (P<10-7). Detailed mapping of the distribution of epithelial types within the columnar lined esophagus identified three patterns of distribution of intestinal metaplasia within long segments of Barrett's esophagus: unifocal, multifocal and diffuse, in 5%, 56% and 39% of the patients respectively. Dysplasia was present in 15% of patients with long segments of Barrett's esophagus and 11% of patients with short segments (NS). CONCLUSION The distribution of intestinal metaplasia within columnar lined esophagus is heterogeneous and three distinct patterns can be identified: unifocal, multifocal and diffuse. Considering the risk of sampling error, the current recommendations concerning the biopsy protocols are mandatory until the validation of new techniques such as chromoendoscopy or magnifying endoscopy.

Abstract
A number of previous studies have reported patients with Barrett's columnar metaplasia who have an increase or decrease in segment length over time. It is not clear whether patients who have an apparent shortening of the metaplastic segment are subsequently at a lower neoplastic risk and those whose segment length appears to increase are at a higher risk of adenocarcinoma development. The aim of this study was to investigate these issues by studying a large cohort of patients from the UK National Barrett's Oesophagus Registry. Medical records of 1533 patients registered with the UK National Barrett's Oesophagus Registry were examined from seven UK centers. Data were extracted on metaplastic segment length at surveillance endoscopies and histological findings on biopsy. Overall changes in segment length, variability in measurement and probability of the development of dysplasia and neoplasia over time were examined. At least two segment lengths were measured in 763 patients. The median change from measured diagnostic length to most outlying measured segment length was 3.0 cm, but overall there was no tendency for segment length to increase or decrease in the majority of patients with a follow up of up to 20 years. Most patients were treated with proton pump inhibitors. One hundred and eighty-six patients had three or more segment lengths over the first 10 years of follow up. No change in risk was demonstrated in these patients where length appeared to consistently increase with time or when it appeared to decrease. Overall, metaplastic columnar-lined esophagus segment length does not change over time, and when an apparent change is observed, this does not influence a risk of dysplasia or adenocarcinoma.

Abstract
OBJECTIVE Longer columnar-lined oesophagus (CLO) segments have been associated with higher cancer risk, but few studies have demonstrated a significant difference in neoplastic risk stratified by CLO segment length. This study establishes adenocarcinoma risk in CLO by segment length. METHODS This is a multicentre retrospective observational study. Medical records of 1000 patients registered from six centres were examined and data extracted on demographic factors, endoscopic features and histopathology of oesophageal biopsies. Adenocarcinoma incidence was evaluated for patients stratified by their diagnostic segment length. RESULTS Seven hundred and eighty-one patients had biopsy-proven CLO and a segment length recorded. Four hundred and ninety patients had at least 1 year of follow-up, providing 2620 patient-years of follow-up for incidence analysis. The overall annual adenocarcinoma incidence was 0.62%/year (95% confidence interval: 0.36-1.01). The annual incidence in the segment length groups was 0.59% (0.19-1.37) in short segment (<or=3 cm), 0.099% (0.025-0.55) in >3 <or=6 cm, 0.98% (0.27-2.52) in >6 <or=9 cm and 2.0% (0.73-4.35) in >9 cm; P=0.004. CONCLUSION This study demonstrates that the neoplastic risk of CLO varies according to segment length, and that overall, the risk of adenocarcinoma development is similar in short-segment and long-segment (>3 cm) CLO. The highest adenocarcinoma risk was found in the longest CLO segments and lowest risk in segments >3 <or=6 cm.

Abstract
BACKGROUND AND AIMS The question of whether an endoscopically normal-appearing esophagogastric junction should be biopsied in patients with gastroesophageal reflux disease is controversial. We have addressed this issue using endoscopy and histopathology. METHODS A total of 114 consecutive patients (58 males) with symptoms of gastroesophageal reflux disease prospectively underwent endoscopy, including biopsy sampling from the esophagogastric junction. Endoscopically visible columnar-lined esophagus was defined by the presence of gastric-type mucosa above the level of the rise of the gastric folds. Histopathology was conducted using the Paull-Chandrasoma classification. RESULTS Of the 114 patients, 85 (74.6%) had endoscopically visible columnar-lined esophagus of length < or =0.5 cm (n = 82), 1 cm (n = 2) and 7 cm (n = 1); 29 patients (25.4%) had a normal endoscopic junction. All patients had histopathologic columnar-lined esophagus. Intestinal metaplasia and low-grade dysplasia was identified in 26 (22.8%) and 5 (4.4%) individuals, respectively, and was not statistically different in endoscopically normal vs. abnormal junction (P = 0.408 for intestinal metaplasia, P = 0.775 for low grade dysplasia). Intestinal metaplasia was independent from endoscopic esophagitis (P = 0.398) and hiatal hernia (P = 0.405). CONCLUSIONS Columnar-lined esophagus cannot be excluded by endoscopy. In patients with gastroesophageal reflux disease, biopsy sampling of normal-appearing junction is recommended for histopathologic exclusion of intestinal metaplasia and low-grade dysplasia.

Abstract
RATIONALE, AIMS AND OBJECTIVES To describe the current practice for the surveillance of patients with Barrett's esophagus, to compare this practice with the national guidelines published by the French Society of Digestive Endoscopy in 1998 and to identify the factors associated with the compliance to guidelines. METHOD To determine the attitudes of French hepatogastroenterologists to screening for Barrett's oesophagus, a postal anonymous questionnaire survey was undertaken. It was sent to 246 hepatogastroenterologists in the Rhone-Alpes area. We defined eight criteria allowed to assess the conformity of practices with the guidelines. We created three topics composed of several criterion. The topics analysed were 'Biopsies', 'Surveillance' and the diagnosis of high grade dysplasia. We studied the factors which could be associated with the compliance with the guidelines. RESULTS The response rate was 81.3%. For 58.0% of the gastroenterologists, endoscopic biopsy sampling were made according to French guidelines (four-quadrant biopsies at 2 cm intervals). Agreement was 78.0% regarding the interval of surveillance for no dysplasia (every 2 or 3 years) and 78.5% regarding the low-grade dysplasia (every 6 or 12 months). For the management of high-grade dysplasia, 28.6% actually confirm the diagnosis by a second anatomopathologist and 42.0% treated by proton pump inhibitor during 2 months. Concerning the biopsies, the young gastroenterologists and gastroenterologists practising in university hospitals had a better adherence to the guidelines (Relative Risk: 2.22, 95% CI 1.25-3.95 and 3.74, 95% CI 1.04-13.47, respectively). The other factors of risk were not statistically significant. CONCLUSIONS The endoscopic follow-up is mostly realized in accordance with the national guidelines. However, there is a wide variability in individual current practice.

Abstract
OBJECTIVES Intestinal metaplasia (IM) and dysplasia in Barrett's esophagus are recognized surrogates for esophageal adenocarcinoma risk. While few would argue with the "hunt for dysplasia," there is a divide regarding the usefulness of the histological confirmation of intestinal metaplasia in endoscopically apparent long segment Barrett's esophagus. We aimed to assess the frequency of intestinal metaplasia in 125 consecutive patients with columnar-lined esophagus and to determine the optimal biopsy protocol to detect intestinal metaplasia. METHODS Two-hundred ninety-six endoscopies were performed over a 4-yr period in Barrett's esophagus segments of mean length 4 cm (range 1-11 cm) at a single center and the resulting biopsies were analyzed retrospectively. Biopsies were all processed with routine hematoxylin and eosin (H&E) staining, and a subset (N=92) was subject to alcian blue/periodic-acid Schiff staining. RESULTS Using H&E staining, we found that the optimum number of biopsies to diagnose intestinal metaplasia was 8 per endoscopy, mean 67.9% endoscopies having intestinal metaplasia. In contrast, if only four were taken the yield was 34.7% with intestinal metaplasia. Unless more than 16 biopsies were taken (100% yield of intestinal metaplasia), no additional significant detection was achieved. Using additional alcian blue/periodic-acid Schiff staining only had a marginal benefit, with 5.4% of new cases of intestinal metaplasia being identified. There is a proximal cephalo-caudal gradient of intestinal metaplasia, especially with increased chronological age, but doing repeat endoscopies on patients did not increase the detection of intestinal metaplasia. CONCLUSIONS The data suggest that at least 8 random biopsies is the minimum to be taken and analyzed with conventional H&E staining to diagnose benign intestinal metaplasia. Taking more biopsies did not statistically increase the diagnosis of intestinal metaplasia except when greater than 16 were taken when 100% yield was obtained.

Abstract
BACKGROUND AND AIMS During endoscopy the stomach is considered to rise at the level of the 'gastric' folds; however, anatomical studies have demonstrated that the proximal gastric folds may in fact be esophageal. This prospective study was designed to assess the histopathology of endoscopically visible proximal gastric folds in patients with gastroesophageal reflux disease. METHODS 35 consecutive patients (20 males) with gastroesophageal reflux disease underwent video endoscopy, including biopsy sampling from the endoscopically visible esophagogastric junction (0 cm, 0.5 cm and 1.0 cm distal to the rise of gastric folds and 0.5 cm and 1.0 cm proximal to it). Endoscopy was digitally recorded and reviewed for assignment of biopsy level. Columnar-lined esophagus and esophagitis were cataloged according to the Paull-Chandrasoma histopathologic classification and the Los Angeles endoscopic classification. RESULTS Endoscopy: Normal endoscopic esophagogastric junction was seen in 11 (31%) patients and visible columnar-lined esophagus < or = 0.5 cm in 24 (69%). HISTOLOGY Columnar-lined esophagus extended 1.0 cm in 22.8% of patients and 0.5 cm in 51.4%, distal to the rise of the gastric folds. In all patients columnar-lined esophagus was interposed between squamous epithelium and gastric oxyntic mucosa. Thus, so-called gastric folds contained mucosa of esophageal origin in all patients. Intestinal metaplasia (Barrett esophagus) was detected in eight (22.9%) patients. CONCLUSIONS Endoscopy cannot exclude histopathologic columnar-lined esophagus within gastric rugae. Thus, visible 'gastric' folds should not be used for definition of the esophagogastric junction but as a reference landmark for biopsy sampling during endoscopy.

Abstract
BACKGROUND AND AIM Barrett's esophagus (BE) is diagnosed when specialized intestinal metaplasia (SIM) is detected histologically in endoscopically suspected columnar-lined esophagus (CLE). It is a premalignant condition and plays a pivotal role in the development of esophageal adenocarcinoma. It has traditionally been believed to affect Asians less frequently. The aim of this study was to determine the prevalence of BE and possible associated risk factors in Korea. METHODS A retrospective analysis of 70 103 patients who had undergone their first upper endoscopies was performed using computerized medical records. Of these, 696 (1%) patients had suspected CLE. After screening by telephone, 480 were enrolled. The clinical and endoscopic characteristics of histologically identifiable BE and endoscopically suspected CLE not confirmed by biopsy (suspected CLE without SIM) were investigated. RESULTS Barrett's esophagus was present in 151 patients (0.22%) with a mean age of 53.8 +/- 10.9 years. BE was more commonly found in men. BE was associated with a set of features distinct from suspected CLE without SIM; older age, greater predominance of male sex, more frequent smoking history, and more frequent acid regurgitation symptom. CONCLUSIONS Barrett's esophagus remains less common in Korea than in Western countries. Old age, male sex, smoking, and acid regurgitation symptom were significant risk factors.

Abstract
BACKGROUND Attention has focused on whether normalization, regression, and development of dysplasia and cancer in specialized intestinal metaplasia (SIM) differ among long-segment Barrett's esophagus (LSBE), short-segment BE (SSBE), and esophagogastric junction SIM (EGJSIM). We prospectively followed a cohort of SIM patients receiving long-term antisecretory medications to determine: (a) histologic normalization (no evidence of SIM on biopsy), (b) change in SIM length, (c) incidence of dysplasia and cancer, and (d) factors associated with normalization. METHODS One hundred forty-eight patients with SIM were identified in our original cohort. Of these, 60.5% (23/38) LSBE, 69.8% (44/63) SSBE, and 72.3% (34/47) EGJSIM patients underwent repeat surveillance over a mean 44.4 +/- 9.7 months. Demographic, clinical, and endoscopic data were obtained. RESULTS (a) With long-term, antisecretory therapy, normalization occurred in 0/23 LSBE, 30% (13/44) of SSBE, and 68% (23/34) of EGJSIM (P < 0.001). (b) Normalization was more likely with EGJSIM (odds ratio [OR] 6.7, CI 2.3-19.3, P= 0.005), female gender (OR 7.3, CI 2.3-23.1, P= 0.001), or absence of hiatal hernia (OR 2.9, CI 1.02-8.06, P= 0.002). (c) A significant decrease in mean SIM length was noted for the entire population (2.5 +/- 0.3 to 2.13 +/- 0.3 cm, P= 0.004). (d) Follow-up incidence of dysplasia and cancer was 26.1% (3 indefinite, 2 low-grade dysplasia [LGD], 1 cancer) for LSBE, 6.8% (2 indefinite, 1 LGD) for SSBE, and none for EGJSIM (P < 0.004). CONCLUSIONS (a) Normalization of SIM occurs most frequently in EGJSIM>SSBE>LSBE. (b) Factors associated with normalization favor less severe GER and shorter segments of SIM. (c) Surveillance of LSBE results in the greatest yield for identifying dysplasia and cancer.

Abstract
BACKGROUND This study was undertaken to compare patients with gastroesophageal reflux disease (GERD) with or without Barrett's esophagus for severity and frequency of symptoms and their response to antireflux surgery. METHODS Eighty patients with GERD and Barrett's esophagus and 93 concurrent patients with GERD alone, all of whom underwent laparoscopic Nissen fundoplication, were compared by using symptom scores graded by a Likert scale. RESULTS Before fundoplication, patients with Barrett's esophagus had higher DeMeester scores. Symptom scores were not different for patients with versus without Barrett's esophagus before or after laparoscopic Nissen fundoplication. CONCLUSIONS Before and after fundoplication, patients with Barrett's esophagus, despite more severe reflux, have symptoms nearly identical in frequency and severity when compared with patients with GERD alone. Regardless of presence of Barrett's, all improve dramatically with laparoscopic Nissen fundoplication. Barrett's esophagus does not impact presentation before or outcome after laparoscopic Nissen fundoplication.

Abstract
OBJECTIVES A globally acceptable definition and classification of gastroesophageal reflux disease (GERD) is desirable for research and clinical practice. The aim of this initiative was to develop a consensus definition and classification that would be useful for patients, physicians, and regulatory agencies. METHODS A modified Delphi process was employed to reach consensus using repeated iterative voting. A series of statements was developed by a working group of five experts after a systematic review of the literature in three databases (Embase, Cochrane trials register, Medline). Over a period of 2 yr, the statements were developed, modified, and approved through four rounds of voting. The voting group consisted of 44 experts from 18 countries. The final vote was conducted on a 6-point scale and consensus was defined a priori as agreement by two-thirds of the participants. RESULTS The level of agreement strengthened throughout the process with two-thirds of the participants agreeing with 86%, 88%, 94%, and 100% of statements at each vote, respectively. At the final vote, 94% of the final 51 statements were approved by 90% of the Consensus Group, and 90% of statements were accepted with strong agreement or minor reservation. GERD was defined as a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. The disease was subclassified into esophageal and extraesophageal syndromes. Novel aspects of the new definition include a patient-centered approach that is independent of endoscopic findings, subclassification of the disease into discrete syndromes, and the recognition of laryngitis, cough, asthma, and dental erosions as possible GERD syndromes. It also proposes a new definition for suspected and proven Barrett's esophagus. CONCLUSIONS Evidence-based global consensus definitions are possible despite differences in terminology and language, prevalence, and manifestations of the disease in different countries. A global consensus definition for GERD may simplify disease management, allow collaborative research, and make studies more generalizable, assisting patients, physicians, and regulatory agencies.

Abstract
OBJECTIVE Barrett's esophagus with the intestinal predominant mucin phenotype is considered to have a higher malignant potential than that with the gastric predominant mucin phenotype. The purpose of this prospective study was to investigate the prevalence of and risk factors for Barrett's esophagus with the intestinal predominant mucin phenotype in patients undergoing endoscopy. MATERIAL AND METHODS A total of 1699 consecutive patients undergoing esophagogastroduodenoscopy were enrolled in the study. A targeted biopsy was performed when endoscopically observed columnar-appearing esophagus was stained with crystal violet. The sample, histologically evidenced as Barrett's esophagus, was immunohistochemically evaluated and categorized as of either gastric or intestinal predominant mucin phenotype. All the patients were requested to complete the structured questionnaire indicating their symptoms and food consumption patterns. Prevalence of and risk factors for Barrett's esophagus with and without the intestinal predominant mucin phenotype were investigated. RESULTS Out of 1668 patients, 629 (37.7%) were found to have endoscopic Barrett's esophagus. In 333 out of 1668 patients (19.9%), histological studies were diagnostic of Barrett's esophagus. One hundred and six of these 333 patients (31.8%) had the intestinal predominant mucin phenotype. Age, male gender and the presence of hiatal hernia were confirmed by multivariate analysis as the independent predictors for the presence of Barrett's esophagus with the intestinal predominant mucin phenotype. CONCLUSIONS Barrett's esophagus with the intestinal predominant mucin phenotype was immunohistochemically found in 6.4% of all study patients. Older age, male gender and the presence of hiatal hernia were the risk factors for the presence of Barrett's esophagus with the intestinal predominant mucin phenotype.

Abstract
OBJECTIVE The aim of this study is to compare the effect of medical and surgical treatment on the history of patients with Barrett esophagus (BE) and histologic evidence of low-grade dysplasia (LGD). SUMMARY BACKGROUND DATA BE is a complication of severe gastroesophageal reflux. It is considered a major risk factor for esophageal adenocarcinoma, which may develop through stages from nondysplastic metaplasia to dysplasia (LGD and high-grade dysplasia). Presently, there are no recommended therapeutic guidelines for patients with LGD. METHODS Between 1998 through 2003, 6592 patients underwent upper endoscopy; 327 of 6592 (5%) patients had BE, and 35 of 327 (10.7%) had LGD. Nineteen patients with LGD were treated with high-dose proton pump inhibitors, and 16 patients underwent laparoscopic Nissen fundoplication. Endoscopic and histologic follow-up was available in all patients after 18 months. We used multiple logistic regression to examine the effect of the 2 treatments on regression of LGD. RESULTS LGD was predominant in men (male-to-female ratio: 1.7:1). Mean age was 58 +/- 13.5 years. Sixty percent of patients had no endoscopic evidence of esophagitis. A regression from LGD to BE was observed in 12 of 19 (63.2%) patients in the medical group and in 15 of 16 (93.8%) patients in the surgical group (statistically significant difference). Differences between the 2 groups were statistically significant (P = 0.03). CONCLUSION The results of our study suggest that surgical treatment may be more effective than medical therapy to modify the natural history of LGD in patients with BE, perhaps because it not only controls acid but also biliopancreatic reflux into the esophagus.

Abstract
Barrett's esophagus is associated with reflux disease and substantially increases the risk of esophageal adenocarcinoma. The authors undertook a systematic review and meta-analysis of the sex ratio for Barrett's esophagus, erosive reflux disease (ERD), and nonerosive reflux disease (non-ERD) to compare these results with the sex ratio for esophageal adenocarcinoma. MEDLINE (US National Library of Medicine, Bethesda, Maryland) (1966-2004) and EMBASE (Reed Elsevier PLC, Amsterdam, Netherlands) (1980-2004) were searched for relevant citations with a highly sensitive search strategy. Studies to be included required a sample size of 50 or more patients and consecutive recruitment at an institute accessible by all. Stata, version 8.2, software (StataCorp LP, College Station, Texas) was used to conduct random effects meta-analyses. Excess heterogeneity was investigated by meta-regression. The Barrett's esophagus meta-analysis gave an overall pooled male/female sex ratio of 1.96/1 (95% confidence interval (CI): 1.77, 2.17/1). For ERD, the pooled male/female sex ratio was 1.57/1 (95% CI: 1.40, 1.76/1) and, for non-ERD, 0.72/1 (95% CI: 0.62, 0.84/1). All of these estimates were associated with substantial heterogeneity (I2 = 81.1%, 92.7%, and 88.8%, respectively). The meta-analysis estimates for ERD and Barrett's esophagus, while showing an excess of males, are substantially lower than similar estimates for esophageal adenocarcinoma. It is important to establish why male Barrett's esophagus and ERD patients are at increased risk of malignancy compared with females.

Abstract
BACKGROUND Both the demographics underlying the sex ratio in the prevalence of Barrett's esophagus (BE) and the status of BE without intestinal metaplasia (IM) are unclear. AIMS To establish the demographics of histologically proven BE, IM+ and IM-, over a 15-yr period from a primary referral, endoscopy unit. PATIENTS AND METHODS For all BE patients aged 20-89 yr, identified between 1982 and 1996, IM+ or IM-, prevalences were calculated per 100 first endoscopies. RESULTS A total of 492 cases of BE, 320 (248 IM+) in males, 175 (127 IM+) in females were identified in 21,899 first endoscopies (10,939 males, 10,960 females). Between ages 20 and 59 yr in males and 20-79 in females, IM+, IM- and all BE prevalences rose by +/-7.36% for each additional year of age (p= 0.92) with, however, a 20-yr age shift between the sexes, resulting in a male:female OR 4.15 95% CI 2.99-5.77. A declining rate of increase in over 59 males resulted in an overall male:female OR 2.14, 95% CI 1.77-2.58. Over the age of 79 yr, BE prevalences/100 first endoscopies fell from a maximum of 5.1 in males and 3.65 in females to 3.38 and 2.53, respectively. CONCLUSION The 4:1 sex ratio and 20-yr age shift between males and females in the prevalence of BE, both IM+ and IM-, found in younger age groups, was the main cause of the overall BE 2:1 sex ratio. The very similar demographics of IM- and IM+ BE suggest they may be two consecutive stages in the same metaplastic process.
