福建地区Barrett食管的发病情况和内镜及临床特点

目的研究福建地区Barrett食管(BE)的发病情况和内镜、临床特点及其与反流性食管炎(RE)的关系。方法根据新标准诊断BE,研究BE患者的内镜下检出率、内镜表现、分型及病理检查结果,分析患者的年龄、性别、症状、幽门螺杆菌(Hp)感染情况及其与RE的关系。结果检出BE为总胃镜检查人数的7.90%,男女之比为1.98,平均年龄(45.1±14.8)岁,仅19.15%有典型反流症状。BE中短节段占81.20%,多为舌状、岛状或包含这2种形状的混合型。食管活检组织病理诊断为肠化型占BE的34.83%,9.88%伴异型增生,胃窦Hp阳性率为39.94%。RE检出率为2.07%,比BE显著降低(P<0.01)。8.42%的BE伴RE,32.11%的RE伴BE。结论福建地区BE患病率较高,多为短节段舌状或岛状,约1/3为肠化型,以中年男性多见,常无症状,与RE无明显相关性,部分伴异型增生。BE的临床意义和预后有待于进一步研究。     

不同类型胃食管反流病发病机制的差异

目的:比较不同类型胃食管反流病(GERD),即反流性食管炎(RE)、非糜烂性反流病(NERD)和Barrett食管(BE)发病机制的差异.方法:113例GERD患者,根据内镜下表现及病理情况分为RE、NERD、BE三组,比较三组患者内镜下表现、食管测压和24 h pH监测指标、合并食管裂孔疝(HH)情况的差异.结果:RE组较NERD组与BE组下食管括约肌压力减低,但无统计学差异.食管体部各段的收缩波幅比较,RE组减低最明显,NERD组减低最少,两组比较P<0.05;无效食管运功比较,RE组较另两组明显增多( P<0.05).RE、NERD、BE组24 h食管pH监测的DeMeester计分分别为90.2、55.2、48.8;RE组以重度酸暴露多见(43%),反流总时间阳性率较高;NERD组以轻度酸暴露多见(45.8%),反流频率阳性率较高;BE组以长反流时间阳性率较高.HH在RE、NERD、BE组中的检出率分别为50%、14.6%、25.7%( P = 0.003).结论:下食管括约肌及食管体部运动功能受损程度、酸反流情况的差异可能是造成三种不同类型GERD食管黏膜损伤表现不同的主要原因.

有关反流性食管炎问题的再思考

我国对胃食管反流病 (GERD)的研究起步较晚，自 1999年 8月烟台制定了反流性食管病 (炎 )诊断及治疗试行方案以来，受到消化界的关注。全国许多医疗单位按照这一方案，对反流性食管炎 (RE)及相关课题，如 Barrett食管 (BE)、 RE及 BE与幽门螺杆菌 (Hp)感染、 RE与 BE随访等，已经或正在进一步研究；在此前，国内有关专著和专题论文发表了不少。现就个人认为一些与 GERD及 RE有关值得思考的问题，借本期重点号提出来供同道们思索、参考。 　　一般认为 RE患者中的肥胖和老年人较多，但老年与中、青年患者在发病上究竟有无差别 ?这…

我国Barrett食管相关性疾病的研究进展

在西方国家,食管腺癌(EAC)发病率逐年增加,且EAC与Barrett食管(BE)密切相关。近年来我国众多学者对BE和EAC发病情况进行了深入研究,但尚无文献对其进行总结分析。本文通过检索PubMed和中国医学文献数据库,分析了近年来有关我国BE和EAC研究的文章,探讨我国BE和EAC的发病情况和临床病理特点。检索词包括"Barrett食管"、"食管腺癌"、"中国人"和"中国"。通过分析发现,我国伴肠化生的BE检出率很低,一般人群为0.06%,有症状者检出率为1.8%。目前已确定我国BE的危险因素有老年和食管裂孔疝,其他可能的危险因素包括胃食管反流病、吸烟和酗酒。我国BE的发生与性别和肥胖无关。内镜下大多数柱状上皮食管和BE呈舌状或岛状,长度2 cm;我国长段BE非常罕见,尤其在女性人群中。近十年台湾和香港地区EAC的发病率很低,部分地区甚至有降低趋势。我国食管下段腺癌较少见,几乎所有胃食管连接(GEJ)处癌均以胃近端为中心生长。柱状上皮食管的临床意义及其是否存在恶变风险目前尚不清楚,需加大样本量进行更深入的研究。     

The frequency of Barrett's esophagus in high-risk patients with chronic GERD

BACKGROUND: The reported frequency of Barrett's esophagus (BE) in patients with reflux symptoms varies from 5% to 15%. The exact frequency of long-segment BE (LSBE) (>3 cm) and short-segment BE (SSBE) (<3 cm) in patients with chronic symptoms of GERD is uncertain. The aim of this study was to determine the frequency of LSBE and SSBE in consecutive patients presenting for a first endoscopic evaluation with GERD as the indication. METHODS: Consecutive patients presenting to the endoscopy unit of a Veterans Affairs Medical Center for a first upper endoscopy with the indication of GERD were prospectively evaluated. Demographic information (gender, race, age), data on tobacco use and family history of esophageal disease, and body mass index (BMI) were recorded for all patients. Before endoscopy, all patients completed a validated GERD questionnaire. The diagnosis of BE was based on the presence of columnar-appearing mucosa in the distal esophagus, with confirmation by demonstration of intestinal metaplasia in biopsy specimens. All patients with erosive esophagitis on the initial endoscopy underwent a second endoscopy to document healing and to rule-out underlying BE. Patients with a history of BE, alarm symptoms (dysphagia, weight loss, anemia, evidence of GI bleeding), or prior endoscopy were excluded. RESULTS: A total of 378 consecutive patients with GERD (94% men, 86% white; median age 56 years, range 27-93 years) were evaluated. A diagnosis of BE was made in 50 patients (13.2%). The median length of Barrett's esophagus (BE) was 1.0 cm (range 0.5-15.0 cm). Of the patients with BE, 64% had short-segment BE (SSBE) (overall SSBE frequency 8.5%). The overall frequency of long-segment BE (LSBE) was 4.8%. A hiatal hernia was detected in 62% of the patients with BE. Of the 50 patients with BE (median age 62 years, range 29-81 years), 47 (94%) were men and 98% were white. Eighteen patients (36%) were using tobacco at the time of endoscopy; 23 (46%) were former users. The median body mass index (BMI) of patients with BE was 27.3 (overweight). There were no significant differences between patients with LSBE and SSBE with respect to age, gender, ethnicity, BMI, and GERD symptom duration. CONCLUSIONS: The frequency of BE in a high-risk patient group (chronic GERD, majority white men, age > 50 years) who sought medical attention is 13.2%, with the majority (64%) having SSBE. These data suggest that the frequency of BE in patients with GERD has not changed. The true prevalence of BE in the general population, including those who do not seek care, is undoubtedly lower, currently and historically. The majority of patients with BE are overweight and have a hiatal hernia. Demographic data for patients with LSBE and SSBE are similar, indicating that these are a continuum of the same process.     

The characteristics of Barrett's esophagus: an analysis of 4120 cases in China

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 patiens. 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.     

Preservation of gastric acid secretion may be important for the development of gastroesophageal junction adenocarcinoma in Japanese people, irrespective of the H. pylori infection status

BACKGROUND: We have previously reported that Helicobacter pylori infection prevents reflux esophagitis (RE) and Barrett's esophagus (BE) by decreasing gastric acid secretion. Gastroesophageal (GE) junction adenocarcinoma, including Barrett's adenocarcinoma, has been thought to be a complication of gastroesophageal reflux disease (GERD). However, the relationship between H. pylori infection, gastric acid secretion, and GE junction adenocarcinoma has not yet been investigated in Japan. The aim of this study was to evaluate this relationship in the Japanese population. METHODS: A total of 168 Japanese patients (RE alone: 80, short-segment BE (SSBE): 16, long-segment BE (LSBE): 20, GE junction adenocarcinoma: 12, distal early gastric cancer (EGC): 40; male/female = 106/62; mean age 61.5 yr) and 80 Japanese control subjects who had no localized lesions in the upper gastrointestinal tract (male/female = 43/37, mean age 58.1 yr) were enrolled for this study. The prevalence of H. pylori infection was determined by biopsy, the rapid urease test, and measurement of the serum H. pylori IgG antibody. Gastric acid secretion was assessed by the endoscopic gastrin test (EGT). RE was diagnosed according to the Los Angeles classification. RESULTS: The prevalence of H. pylori infection in the patients with RE alone (30%) was significantly lower than that in control subjects (71.2%). There was also a tendency for the prevalence of H. pylori infection to be lower in patients with BE (SSBE, 18.7%; LSBE, 0%) when compared to that in patients with RE alone. On the other hand, while the prevalence of H. pylori infection in patients with GE junction adenocarcinoma (58.3%) was significantly lower than that in patients with EGC (87.5%), it tended to be higher than that in patients with RE alone or BE. The mean EGT value in patients with RE alone (3.74 mEq/10 min) was significantly higher than that in control subjects (1.83). The mean EGT value in patients with BE (SSBE, 4.74; LSBE, 4.76) tended to be even higher than that in patients with RE alone. The mean EGT value in patients with GE junction adenocarcinoma (3.94) was significantly higher than that in control subjects and patients with EGC (0.67), but it was comparable to that independent of the H. pylori infection status in patients with RE alone or BE. CONCLUSION: Preservation of gastric acid secretion may be important for the development of GE junction adenocarcinoma in Japanese people, irrespective of the H. pylori infection status.     

Barrett＇s esophagus and its correlation with gastroesophageal reflux in Chinese

AIM- To study the prevalence of Barrett‘s esophagus in Chinese and its correlation with gastroesophageal reflux. METHODS: This study was carded out in a large prospective series of 391 patients who had undergone upper endoscopy. The patients were divided into 3 groups according to the position of squamocolumnar junction (SC3). Reflux esophagitis (RE) and its degree were recorded. Intestinal metaplasia (IM) in biopsy specimen was typed according to histochemistry and HE and alcian blue (pH2.5) staining separately. Results correlating with clinical, endoscopic, and pathological data were analysed. RESULTS: The prevalence of IM endoscopically appearing Long-segment Barrett‘s Esophagus (LSBE) was 26.53%, Short-segment Barrett‘s Esophagus (SSBE) was 33.85% and gastroesophageal junction (GEJ) was 34.00%. IM increased with age of above 40 years old and no difference was found between male and female. Twelve were diagnosed as dysplasia (7 low -grade, 5 high-grade), 16 were diagnosed as cardiac adenocarcinoma and 1 as esophageal adenocarcinoma. The more far away the SCJ moved upward above GEJ, the higher the prevalence and the more severe the RE were. CONCLUSION: There was no difference of the prevalence of IM in different places of SCJ, and IM increased with age of above 40 years old. It is important to pay attention to dysplasia in the distal esophagus and gastro-esophageal junction, and adenocarcinoma is more common in cardia than in esophagus. BE is a consequence of gastroesophageal reflux disease.     

Prevalence and risk factors of Barrett's esophagus in patients undergoing endoscopy for upper gastrointestinal symptoms

OBJECTIVE: To investigate the prevalence of Barrett's esophagus (BE) and its risk factors in patients undergoing endoscopy for upper gastrointestinal symptoms in a Chinese tertiary referral medical center. METHODS: All consecutive patients receiving an endoscopy for upper gastrointestinal symptoms in our medical center from September to December 2007 were recruited. BE was explored for at endoscopy when a suspected columnar-lined esophagus was found. Patients with specialized intestinal metaplasia in the distal esophagus were defined as having BE. RESULTS: A total of 2022 patients (1053 male and 969 female) were recruited. The patients were aged 18 to 88 years and with a mean age of 46.97 ± 14.84 years. BE was found in 21 patients (15 male and 6 female), a prevalence of 1.0% of all patients receiving endoscopy for upper gastrointestinal symptoms in our medical center. One of the 21 patients had low-grade dysplasia. By logistic multivariate analysis, age (OR 1.03; 95% CI, 1.00, 1.07) and reflux esophagitis (OR 4.44; 95% CI, 1.22, 16.17) were factors associated significantly with BE. CONCLUSION: The prevalence of BE in our study was lower than that reported in other studies, especially in studies from developed countries. Older age and reflux esophagitis may be the risk factors for developing BE.     

Barrett's esophagus is common in older men and women undergoing screening colonoscopy regardless of reflux symptoms

BACKGROUND: Although Barrett's esophagus (BE) is the precursor of esophageal adenocarcinoma (ACA), most patients with ACA present outside of a BE surveillance program. This could be due to undiagnosed symptomatic GER and BE or BE/ACA occurring in patients without reflux symptoms. We have, therefore, studied the prevalence of BE and symptom status in older patients referred for colonoscopy. METHODS: All patients referred for outpatient colonoscopy were eligible if they were at least 65 yr old and had not previously undergone esophagoscopy. After informed consent, the patients completed detailed GER questionnaires. During the research endoscopy, the endoscopist recorded the squamocolumnar junction (SCJ) as either long-segment BE (LSBE), short-segment BE (SSBE), or normal. If the SCJ was felt to be "irregular" the endoscopist was asked to predict, in their judgment, if BE was present. All patients had biopsies below the SCJ, which were examined by a gastrointestinal pathologist who was blinded to the endoscopic findings. RESULTS: BE esophagus was present in 50 of the 300 patients studied (16.7%). BE was more common in men (35 of 161, 21.7%) than in women (15 of 139, 10.8%) (p < 0.025). GERD symptoms were reported in 106 patients (35%) and BE was present in 19.8% of symptomatic and 14.9% of asymptomatic cases (NS). The majority of the BE in this study was less than 3 cm in length (92%). The questionnaires did not predict the presence of BE. CONCLUSIONS: BE is common in unscreened male and female patients at least 65 yr of age who are referred for colonoscopy. Men were more likely than women to have BE although it occurred in both sexes. Reflux symptoms were fairly common but a poor predictor of BE.

Detection of Barrett's esophagus after endoscopic healing of erosive esophagitis

BACKGROUND: The presence of erosive esophagitis (EE) in patients presenting for upper endoscopy may prevent the detection of underlying Barrett's esophagus (BE) in the distal esophagus. AIM: To prospectively determine the proportion of patients detected with BE upon repeat endoscopy after healing of EE. METHODS: Patients with endoscopically confirmed EE without BE were treated with standard doses of acid suppression therapy and a repeat endoscopy was performed to assess the presence of BE. If columnar mucosa was visualized in the distal esophagus, targeted biopsies were obtained and all biopsies were evaluated for the presence of intestinal metaplasia. BE was defined as columnar mucosa in the distal esophagus with intestinal metaplasia on biopsy. RESULTS: A total of 172 patients with reflux symptoms were diagnosed with EE without BE on initial endoscopy. They were treated with standard doses of proton pump inhibitor therapy, and after a mean duration of 11 wk (range 8-16 wk), a repeat endoscopy was performed to confirm healing of EE and to document the presence of BE. On repeat endoscopy, EE was completely healed in 116 patients (67%), and of those, BE was suspected in 32 patients (i.e., columnar-lined distal esophagus) and was confirmed in 16 patients (13.8%). In the 56 patients with persistent EE on repeat endoscopy, columnar mucosa in areas of previously healed esophagitis was visualized in 8 and confirmed in 5 patients (8.9% of nonhealed cases). Overall, 21 (12%) patients were confirmed with BE on repeat endoscopy; all men, mean age 61 yr with a median BE length of 0.5 cm (range 0.5-5 cm, interquartile range 0.5 cm). The majority of these patients (N = 19) had short segment Barrett's esophagus (SSBE) (i.e., length <3 cm). CONCLUSIONS: In patients with EE undergoing treatment with acid suppressive therapy, BE (mainly SSBE) is detected in approximately 12% of patients on repeat endoscopy. Patients with reflux symptoms undergoing endoscopy for the detection of BE (i.e., screening) should be treated with acid suppressive therapy prior to endoscopy to enhance the yield of BE. Alternatively, if the goal is to document BE and if EE is found at the initial endoscopy, then repeat endoscopy may be considered after acid suppressive therapy.
