Abstract
BACKGROUND Esophagectomy has been the standard treatment for Barrett's esophagus (BE) with high-grade dysplasia (HGD) and intramucosal cancer (IMC). Recently, endoscopic mucosal resection (EMR) and radiofrequency ablation (RFA) have become the preferred treatment for these patients in some centers. We report a single institution series of patients undergoing endoscopic management of HGD and IMC. METHODS Nineteen patients underwent endoscopic treatment for HGD or IMC between 2009 and 2012. The primary outcome measure was progression of BE necessitating esophagectomy. Secondary outcomes included complete eradication of intestinal metaplasia (CE-IM), complete eradication of dysplasia (CE-D), recurrence or progression of BE or dysplasia, and complications. Patients were followed for a median follow-up interval of 19 months following completion of RFA treatment. RESULTS Three patients (16 %) had a presenting diagnosis of IMC, and 16 (84 %) were treated for HGD. Twelve (63 %) had long-segment BE; the median length of BE was 5 cm. Ten (53 %) patients underwent EMR prior to RFA. CE-D was achieved in 88 % of patients, and CE-IM was achieved in 65 % of patients. A median of 2 (1-7) treatments were required, and there were no immediate post-procedure complications. Two patients developed recurrent dysplasia following complete eradication of BE, and each case was successfully managed with repeat RFA. Three patients (16 %) required esophagectomy within 6 months following RFA. A complete surgical resection was achieved in each case, and none of the patients developed lymph node metastases. CONCLUSIONS Complete eradication of HGD and IMC can be achieved via endoscopic therapy, thus avoiding esophagectomy in the majority of patients. However, a subset of patients will fail this treatment approach and will require surgical resection. With aggressive endoscopic treatment and surveillance, these patients can be identified at an early stage while curative resection is still possible.

Abstract
Barrett esophagus develops when metaplastic columnar epithelium predisposed to develop adenocarcinoma replaces esophageal squamous epithelium damaged by gastroesophageal reflux disease. Although several types of columnar metaplasia have been described in Barrett esophagus, intestinal metaplasia with goblet cells currently is required for a definitive diagnosis in the United States. Studies indicate that the risk of adenocarcinoma for patients with nondysplastic Barrett esophagus is only 0.12% to 0.38% per year, which is substantially lower than previous studies had suggested. Nevertheless, the incidence of esophageal adenocarcinoma continues to rise at an alarming rate. Regular endoscopic surveillance for dysplasia is the currently recommended cancer prevention strategy for Barrett esophagus, but a high-quality study has found no benefit of surveillance in preventing deaths from esophageal cancer. Medical societies currently recommend endoscopic screening for Barrett esophagus in patients with multiple risk factors for esophageal adenocarcinoma, including chronic gastroesophageal reflux disease, age of 50 years or older, male sex, white race, hiatal hernia, and intra-abdominal body fat distribution. However, because the goal of screening is to identify patients with Barrett esophagus who will benefit from endoscopic surveillance and because such surveillance may not be beneficial, the rationale for screening might be made on the basis of faulty assumptions. Endoscopic ablation of dysplastic Barrett metaplasia has been reported to prevent its progression to cancer, but the efficacy of endoscopic eradication of nondysplastic Barrett metaplasia as a cancer preventive procedure is highly questionable. This review discusses some of these controversies that affect the physicians and surgeons who treat patients with Barrett esophagus. Studies relevant to controversial issues in Barrett esophagus were identified using PubMed and relevant search terms, including Barrett esophagus, ablation, dysplasia, radiofrequency ablation, and endoscopic mucosal resection.

Abstract
Barrett's esophagus is an acquired clinical condition in which the squamous epithelium of the distal esophagus is replaced by a columnar epithelium. The diagnosis requires histological confirmation of specialized intestinal metaplasia, in which goblet cells must be present. Barrett's esophagus is a risk factor for the development of esophageal adenocarcinoma, a tumor with an incidence and mortality have increased alarmingly in recent years in the western world. It has been estimated that the annual incidence of cancer in patients with Barrett's esophagus has increased from 0.2-2%. Once diagnosed, Barrett's esophagus is estimated to have an annual neoplastic transformation rate of 0.5% per patient. The highlights of the endoscopic diagnosis and treatment are reviewed here, as well as the screening and monitoring of this process.

Abstract
The clinical utility of endoscopic ultrasound (EUS) for staging patients with Barrett's esophagus and high-grade dysplasia (HGD) or intramucosal carcinoma (IMC) prior to endoscopic therapy is unclear. We performed a retrospective analysis of patients with HGD or IMC referred to an American medical center for endoscopic treatment between 2004 and 2010. All patients had pretreatment staging by EUS. We examined the frequency that EUS findings consistent with advanced disease (tumor invasion into the submucosa, lymph node involvement, or regional metastasis) led to a change in management. The analysis was stratified by nodularity and pre-EUS histology. We identified one hundred thirty-five patients with HGD (n = 106, 79%) or IMC (n = 29, 21%) had staging by EUS (79 non-nodular, 56 nodular). Pathologic lymph nodes or metastases were not found by EUS. There were no endosonographic abnormalities noted in any patient with non-nodular mucosa (0/79). Abnormal EUS findings were present in 8/56 patients (14%) with nodular neoplasia (five IMC, three HGD). Endoscopic mucosal resection was performed in 44 patients with a nodule, with 13% (6/44) having invasive cancer. In nodular neoplasia, the EUS and endoscopic mucosal resection were abnormal in 24% (5/21) and 40% (6/15) of those with IMC and 9% (3/35) and 0% (0/29) of those with HGD, respectively. In this study we found that EUS did not alter management in patients with non-nodular HGD or IMC. Because the diagnostic utility of EUS in subjects with non-nodular Barrett's esophagus is low, the value of performing endoscopic mucosal resection in this setting is questionable. For patients with nodular neoplasia, resection of the nodule with histological examination had greater utility than staging by EUS.

Abstract
BACKGROUND Barrett's esophagus (BE) is the main risk factor for esophageal adenocarcinoma. Its therapeutic approach is controversial and surgical treatment in the presence of high-grade intraepithelial neoplasia may be indicated. Endoscopic approach is an alternative with lower mortality and morbidity rates and favorable results. OBJECTIVE To define the best option, according to literature, to treat Barrett's Esophagus. DESIGN Systematic review of PUBMED, EMBASE, LILACS, and Cochrane Library databases was conducted and articles of randomized, controlled studies on BE endoscopic ablative treatment were selected. The systematic review through PUBMED retrieved results with higher evidence level and available recommendation grade regarding BE ablative therapy. Nine articles on randomized, controlled studies classified as A or B according to the Oxford table were selected. Cryotherapy, laser, photodynamic therapy (PDT), multipolar electrocoagulation (MPEC), and ablation through argon plasma coagulation (APC) and radiofrequency were considered ablation therapies. PATIENTS 649 patients from 10 different studies were analysed. RESULTS PDT was found to present an increase in treatment failure compared with APC, NNH = -7. BE ablation through MPEC or APC was found to have similar risk for treatment failure in meta-analysis. PDT associated with proton pump inhibitor (PPI) is beneficial for BE ablation regarding PPI use alone, NNT = 2.Radiofrequency with PPI is an efficient method to reduce risk of treatment failure, NNT = 1. CONCLUSIONS There are no studies demonstrating the benefit of indicating cryotherapy or laser therapy for BE endoscopic approach. APC ablation was found to have superior efficacy compared with PDT and ablation through APC and MPEC was found to present effective, similar results. Radiofrequency is the most recent approach requiring comparative studies for indication.

Abstract
AIM: To assess NY-ESO-1 expression in a cohort of esophageal adenocarcinomas.
METHODS: A retrospective search of our tissue archive for esophageal resection specimens containing esophageal adenocarcinoma was performed, for cases which had previously been reported for diagnostic purposes, using the systematised nomenclature of human and veterinary medicine coding system. Original haematoxylin and eosin stained sections were reviewed, using light microscopy, to confirm classification and tumour differentiation. A total of 27 adenocarcinoma resection specimens were then assessed using immunohistochemistry for NY-ESO-1 expression: 4 well differentiated, 14 moderately differentiated, 4 moderate-poorly differentiated, and 5 poorly differentiated.
RESULTS: Four out of a total of 27 cases of esophageal adenocarcinoma examined (15%) displayed diffuse cytoplasmic and nuclear expression for NY-ESO-1. They displayed a heterogeneous and mosaic-type pattern of diffuse staining. Diffuse cytoplasmic staining was not identified in any of these structures: stroma, normal squamous epithelium, normal submucosal gland and duct, Barrett’s esophagus (goblet cell), Barrett’s esophagus (non-goblet cell) and high grade glandular dysplasia. All adenocarcinomas showed an unexpected dot-type pattern of staining at nuclear, paranuclear and cytoplasmic locations. Similar dot-type staining, with varying frequency and size of dots, was observed on examination of Barrett’s metaplasia, esophageal submucosal gland acini and the large bowel negative control, predominantly at the crypt base. Furthermore, a prominent pattern of apical (luminal) cytoplasmic dot-type staining was observed in some cases of Barrett’s metaplasia and also adenocarcinoma. A further morphological finding of interest was noted on examination of haematoxylin and eosin stained sections, as aggregates of lymphocytes were consistently noted to surround submucosal glands.
CONCLUSION: We have demonstrated for the first time NY-ESO-1 expression by esophageal adenocarcinomas, Barrett’s metaplasia and normal tissues other than germ cells.

Abstract
IMPORTANCE Barrett esophagus containing low-grade dysplasia is associated with an increased risk of developing esophageal adenocarcinoma, a cancer with a rapidly increasing incidence in the western world. OBJECTIVE To investigate whether endoscopic radiofrequency ablation could decrease the rate of neoplastic progression. DESIGN, SETTING, AND PARTICIPANTS Multicenter randomized clinical trial that enrolled 136 patients with a confirmed diagnosis of Barrett esophagus containing low-grade dysplasia at 9 European sites between June 2007 and June 2011. Patient follow-up ended May 2013. INTERVENTIONS Eligible patients were randomly assigned in a 1:1 ratio to either endoscopic treatment with radiofrequency ablation (ablation) or endoscopic surveillance (control). Ablation was performed with the balloon device for circumferential ablation of the esophagus or the focal device for targeted ablation, with a maximum of 5 sessions allowed. MAIN OUTCOMES AND MEASURES The primary outcome was neoplastic progression to high-grade dysplasia or adenocarcinoma during a 3-year follow-up since randomization. Secondary outcomes were complete eradication of dysplasia and intestinal metaplasia and adverse events. RESULTS Sixty-eight patients were randomized to receive ablation and 68 to receive control. Ablation reduced the risk of progression to high-grade dysplasia or adenocarcinoma by 25.0% (1.5% for ablation vs 26.5% for control; 95% CI, 14.1%-35.9%; P < .001) and the risk of progression to adenocarcinoma by 7.4% (1.5% for ablation vs 8.8% for control; 95% CI, 0%-14.7%; P = .03). Among patients in the ablation group, complete eradication occurred in 92.6% for dysplasia and 88.2% for intestinal metaplasia compared with 27.9% for dysplasia and 0.0% for intestinal metaplasia among patients in the control group (P < .001). Treatment-related adverse events occurred in 19.1% of patients receiving ablation (P < .001). The most common adverse event was stricture, occurring in 8 patients receiving ablation (11.8%), all resolved by endoscopic dilation (median, 1 session). The data and safety monitoring board recommended early termination of the trial due to superiority of ablation for the primary outcome and the potential for patient safety issues if the trial continued. CONCLUSIONS AND RELEVANCE In this randomized trial of patients with Barrett esophagus and a confirmed diagnosis of low-grade dysplasia, radiofrequency ablation resulted in a reduced risk of neoplastic progression over 3 years of follow-up.

Abstract
BACKGROUND Patients with gastroesophageal reflux disease (GERD) often seek alternative therapy for inadequate symptom control, with over 40% not responding to medical treatment. We evaluated the long-term safety, efficacy, and durability of response to radiofrequency treatment of the lower esophageal sphincter (Stretta). METHODS Using an intent-to-treat analysis, we prospectively assessed 217 patients with medically refractory GERD before and after Stretta. There was no concurrent control group in the study. Primary outcome measure was normalization of GERD-health-related quality of life (GERD-HRQL) in 70% or greater of patients at 10 years. Secondary outcomes were 50% reduction or elimination of proton pump inhibitors (PPIs) and 60% or greater improvement in satisfaction at 10 years. Successful treatment was defined as achievement of secondary outcomes in a minimum of 50% of patients. Complications and effect on existing comorbidities were evaluated. The results of a 10-year study are reported. RESULTS The primary outcome was achieved in 72% of patients (95% confidence interval 65-79). For secondary outcomes, a 50% or greater reduction in PPI use occurred in 64% of patients, (41% eliminating PPIs entirely), and a 60% or greater increase in satisfaction occurred in 54% of patients. Both secondary endpoints were achieved. The most common side effect was short-term chest pain (50%). Pre-existing Barrett's metaplasia regressed in 85% of biopsied patients. No cases of esophageal cancer occurred. CONCLUSIONS In this single-group evaluation of 217 patients before and after Stretta, GERD-HRQL scores, satisfaction, and PPI use significantly improved and results were immediate and durable at 10 years.

Abstract
Barrett's esophagus (BE) with dysplasia is generally accepted as the precursor to oesophageal cancer. Thus, methods to eradicate BE and dysplasia have been evaluated. Recently, radiofrequency ablation (RFA) has shown promising results with few adverse effects. The studies concerning RFA are, however, small and heterogeneous. Only six studies have included more than 100 patients and only one is a prospective randomized trial. The purpose of this article is to describe the treatment of BE and especially the indications and challenges of RFA, including complications, buried glands and recurrence.

Abstract
Barrett's esophagus occurs in a little less than 2% of the population. Of the patients, very few develop esophageal adenocarcinoma, and on the other hand only a small part of esophageal adenocarcinoma patients are diagnosed with Barrett's lesion. If Barrett's lesion has a separate visible elevated or depressed lesion it should first be treated with endoscopic mucosal resection, and thereafter the remaining Barrett's lesion should be destructed by a new technique called radiofrequency ablation, RFA. After destruction of the aberrant mucosal lesion with RFA it will be replaced with normal esophageal mucosa and the risk for malignant trasformation is dimished near to zero. RFA is considered the first-line treatment treatment option of dysplastic Barrett's esophagus.

Abstract
AIM: To investigate a classification of endocytoscopy (ECS) images in Barrett’s esophagus (BE) and evaluate its diagnostic performance and interobserver variability.
METHODS: ECS was applied to surveillance endoscopic mucosal resection (EMR) specimens of BE ex-vivo. The mucosal surface of specimen was stained with 1% methylene blue and surveyed with a catheter-type endocytoscope. We selected still images that were most representative of the endoscopically suspect lesion and matched with the final histopathological diagnosis to accomplish accurate correlation. The diagnostic performance and inter-observer variability of the new classification scheme were assessed in a blinded fashion by physicians with expertise in both BE and ECS and inexperienced physicians with no prior exposure to ECS.
RESULTS: Three staff physicians and 22 gastroenterology fellows classified eight randomly assigned unknown still ECS pictures (two images per each classification) into one of four histopathologic categories as follows: (1) BEC1-squamous epithelium; (2) BEC2-BE without dysplasia; (3) BEC3-BE with dysplasia; and (4) BEC4-esophageal adenocarcinoma (EAC) in BE. Accuracy of diagnosis in staff physicians and clinical fellows were, respectively, 100% and 99.4% for BEC1, 95.8% and 83.0% for BEC2, 91.7% and 83.0% for BEC3, and 95.8% and 98.3% for BEC4. Interobserver agreement of the faculty physicians and fellows in classifying each category were 0.932 and 0.897, respectively.
CONCLUSION: This is the first study to investigate classification system of ECS in BE. This ex-vivo pilot study demonstrated acceptable diagnostic accuracy and excellent interobserver agreement.

Abstract
Laparoscopic fundoplication (LF) is the treatment of choice for gastroesophageal reflux disease (GERD).Our paper evaluates post LF quality of life (QL). Patients treated between January 2008 and May 2011 by the same surgeon were asked to fill in the Velanovich questionnaires for Gastro - Oesophageal Reflux Disease - Health Related Quality of Life (GERD-HRQL). The 10 questions were designed to assess GERD specific symptoms prior to (part A) and after surgery (part B). The Velanovich score is 0 if the patient is asymptomatic and 50 if the symptoms are at maximum intensity. Only 32 out of the 54 patients operated during the study filled in the questionnaire:28 patients (87.5%) had hiatus hernia (HH), 16 cases were associated with reflux erosive esophagitis (EE), 4 patients had non-erosive reflux disease (NERD) and one had Barrett's esophagus (BE). We used Toupet partial posterior fund oplication for 12 patients and Nissen total fundoplication for 20 patients. The short gastric vessels were divided in all patients.The female - male ratio was 21:11 with a mean age of 55.13 years and the mean follow up period for questionnaire B was of25.2 months. The Velanovich A score was 29.9 Â+-10.9, and the follow up B score was 3.4Â+-2.4 (CI (95%) 22.9-39.9; p 0.05).There were no B score statistical differences between sex ratio(3.9 vs 2.4) and type of fundoplication (Nissen 3.2 vs Toupet4.1). 29 patients (90.62%) declared that their QL improved after surgery. The main indication for surgery present in almost every patient included in this study was the presence of theHH and RE. LF improved the quality of life of patients with GERD. There were no statistical differences of the Velanovich score according to GERD stage (EE, NERD with or without HH), sex ratio and type of LF, Toupet or Nissen.

Abstract
AIM Some operative techniques in fundoplication seem to increase the incidence of obstructive symptoms. Some authors believe that using intraesophageal bougie and preparing a short and floppy valve in laparoscopic Nissen fundoplication will help to decrease any possible tight crus repair and wrap and so it is effective to decrease the prevalence of postoperative dysphagia. The aim of this study is to show that there is no absolute benefit of routine insertion of a bougie during laparoscopic Nissen fundoplication in relation to post-operative dysphagia. METHODS All patients who underwent laparoscopic Nissen fundoplication by a single surgeon between January 2001 and August 2011 were reviewed retrospectively. Esophageal bougie intubation was performed in none of the 154 patients. The operation technique, the duration of the operation, hospital stay and the improvement of the symptoms were assessed. The patients who had esophagitis with Barrett's esophagus and who had hiatal hernia that could not get benefit from medical therapy, were selected for the surgery. Laparoscopic Nissen fundoplication with cruroraphy were done in all patients. RESULTS Ninety-six of the patients were female and 58 were male. The mean symptom duration was 3.6±0.6 years. The only complication was dysphagia. In eighth week, dysphagia resolved in all patients. CONCLUSION Laparoscopic Nissen fundoplication can be safely performed without the routine use of an esophageal bougie and it does not increase the postoperative dysphagia rate.

Abstract
BACKGROUND & AIMS In patients with Barrett's esophagus (BE), radiofrequency ablation (RFA) safely and effectively eradicates dysplasia and intestinal metaplasia. We aimed to determine the efficacy and durability of RFA for patients with dysplastic and nondysplastic BE. METHODS We performed a systematic review and meta-analysis of studies identified in PubMed and EMBASE that reported the proportion of patients treated with RFA who had complete eradication of dysplasia (CE-D) and intestinal metaplasia (CE-IM), and the proportion of patients with recurrent IM after successful treatment. Pooled estimates of CE-D, CE-IM, IM recurrence, and adverse events were calculated. RESULTS We identified 18 studies of 3802 patients reporting efficacy and 6 studies of 540 patients reporting durability. Ten were prospective cohort studies, 9 were retrospective cohort studies, and 1 was a randomized trial. CE-IM was achieved in 78% of patients (95% confidence interval [CI], 70%-86%) and CE-D was achieved in 91% (95% CI, 87%-95%). After eradication, IM recurred in 13% (95% CI, 9%-18%). Progression to cancer occurred in 0.2% of patients during treatment and in 0.7% of those after CE-IM. Esophageal stricture was the most common adverse event and was reported in 5% of patients (95% CI, 3%-7%). Confidence in most summary estimates was limited by a high degree of heterogeneity, which did not appear to be caused by single outlier studies. CONCLUSIONS Treatment of BE with RFA results in CE-D and CE-IM in a high proportion of patients, with few recurrences of IM after treatment and a low rate of adverse events. Despite the large amount of study heterogeneity, these data provide additional information for patients and providers to make informed treatment decisions.

Abstract
To treat Barrett’s esophagus (BE), radiofrequency ablation or cryotherapy are effective treatments for eradicating BE with dysplasia and intestinal metaplasia, and reduce the rates of Barrett’s esophageal adenocarcinoma (BAC). However, patients with BE and dysplasia or early cancer who achieved complete eradication of intestinal metaplasia, BE recurred in 5% within a year, requiring expensive endoscopic surveillances. We performed endoscopic submucosal dissection as complete radically curable treatment procedure for BE with dysplasia, intestinal metaplasia and BAC.

Abstract
BACKGROUND Liquid nitrogen endoscopic spray cryotherapy can safely and effectively eradicate high-grade dysplasia in Barrett's esophagus (BE-HGD). Long-term data on treatment success and safety are lacking. OBJECTIVE To assess the long-term safety and efficacy of spray cryotherapy in patients with BE-HGD. DESIGN Single-center, retrospective study. SETTING Tertiary-care referral center. PATIENTS A total of 32 patients with BE-HGD of any length. INTERVENTION Patients were treated with liquid nitrogen spray cryotherapy every 8 weeks until complete eradication of HGD (CE-HGD) and intestinal metaplasia (CE-IM) was found by endoscopic biopsy. Surveillance endoscopy with biopsies was performed for at least 2 years. MAIN OUTCOME MEASUREMENTS CE-HGD, CE-IM, durability of response, disease progression, and adverse events. RESULTS CE-HGD was 100% (32/32), and CE-IM was 84% (27/32) at 2-year follow-up. At last follow-up (range 24-57 months), CE-HGD was 31/32 (97%), and CE-IM was 26/32 (81%). Recurrent HGD was found in 6 (18%), with CE-HGD in 5 after repeat treatment. One patient progressed to adenocarcinoma, downgraded to HGD after repeat cryotherapy. BE segment length ≥3 cm was associated with a higher recurrence of IM (P = .004; odds ratio 22.6) but not HGD. No serious adverse events occurred. Stricture was seen in 3 patients (9%), all successfully dilated. LIMITATIONS Retrospective study design, small sample size. CONCLUSION In patients with BE-HGD, liquid nitrogen spray cryotherapy has an acceptable safety profile and success rate for eliminating HGD and IM and is associated with a low rate of recurrence or progression to cancer with long-term follow-up.

Abstract
The definition of Barrett esophagus is currently under discussion. It is now suggested that a distal esophagus coated with cylinder epithelium with cardia-fundus mucosa should also be classified as Barrett esophagus because the risk of cancer is significantly increased even without histological evidence of intestinal metaplasia with goblet cells. The results of recent epidemiological investigations imply that the cancer risk of cylinder cell metaplasia and low grade intraepithelial neoplasia in Barrett esophagus has previously been overestimated. The histological detection of dysplasia still remains the best biomarker for estimation of the risk of cancer of Barrett esophagus. Exact determination of invasion depth in the mucosa, respective submucosa is now established as prognostic marker for overall survival in Patients with early carcinomas and this classification is useful for therapy decisions (endoscopic versus surgical removal). In advanced Barrett carcinoma following neoadjuvant therapy the lymph node status (ypN) is a better prognostic factor than the ypT category. In metastasized tumors therapies targeting HER2/new, EGFR or c-Met have been investigated explicitly in Barrett carcinoma only in phase I/II studies, whereby the predictive value of appropriate molecular pathology investigations is not yet reliably established.

Abstract
BACKGROUND There are limited data on the effect of endoscopic mucosal resection (EMR) on changes of histopathologic diagnosis for Barrett's esophagus (BE) patients undergoing endoscopic eradication therapy (EET); especially those without visible lesions. AIM To compare the frequency of changes of diagnosis by EMR compared with pre-EMR biopsy diagnosis for patients with and without visible lesions. METHODS In this multicenter outcomes project, patients with Barrett's-related neoplasia undergoing EET at three tertiary-care centers were included. Patients undergoing biopsies followed by EMR within six months were included. The main outcome measures were frequency of overall change of histopathologic diagnosis, change based on pre-EMR biopsy diagnosis, and change based on the presence of visible lesions. RESULTS One-hundred and thirty-eight BE patients (low-grade dysplasia (LGD) 15 (10.9 %), high-grade dysplasia (HGD) 87 (63 %), esophageal adenocarcinoma (EAC) 36 (26.1 %)) were included; 114 (82.6 %) patients had visible lesions. EMR resulted in a change of diagnosis for 43 (31.1 %) patients (upgrade 14 (10.1 %); downgrade 29 (21 %)). For HGD patients, EMR downstaged dysplasia grade for 17 (19.5 %) cases and upstaged it to EAC for nine (10.3 %) cases. There was a change of diagnosis for 26 (29.9 %) HGD patients, irrespective of the presence or absence of visible lesions (p = 0.76). For EAC patients, EMR downstaged dysplasia grade in 10 (27.8 %) cases. There was a change of diagnosis for 10 (27.8 %) EAC patients, irrespective of the presence or absence of endoscopically visible lesions (p = 0.48). CONCLUSIONS EMR results in a change of diagnosis for approximately 30 % of BE patients with early neoplasia (with and without visible lesions) referred for EET.

Abstract
AIM Centralisation of oesophageal resection for cancer remains an area of debate. However, no consensus for the requirements of high volume centres yet exists and some low volume centres have been able to produce a comparable outcome. With the small population of New Zealand more than one high volume centre might not be achievable. We reviewed our series of oesophageal resections and compared them to outcomes in the literature to challenge the need for only high volume centres within New Zealand METHODS A retrospective analysis of all consecutive oesophagogastrectomies performed in Christchurch Public Hospital (Christchurch City, New Zealand) from January 1998 until June 2009 was undertaken. RESULTS Within this period 128 oesophagogastrectomies were performed. Median admission duration was 12 days. The overall complication rate was 53.9% of which 5.5% was an anastomotic leak. Combined in-hospital and 30-day-mortality was 1.6% (2/128). The 5-year-survival was 32.4% for adenocarcinoma and 47.7% for squamous cell carcinoma. Conclusion This series has shown that a low volume centre within New Zealand is able to deliver a satisfactory level of care for oesophagectomy. Given New Zealand's low population density it is debatable to what extent care should be centralised for treatment of oesophageal carcinoma.

Abstract
BACKGROUND & AIMS The existence of slowly cycling, adult stem cells has been challenged by the identification of actively cycling cells. We investigated the existence of uncommitted, slowly cycling cells by tracking 5-iodo-2'-deoxyuridine (IdU) label-retaining cells (LRCs) in normal esophagus, Barrett's esophagus (BE), esophageal dysplasia, adenocarcinoma, and healthy stomach tissues from patients. METHODS Four patients (3 undergoing esophagectomy, 1 undergoing esophageal endoscopic mucosal resection for dysplasia and an esophagectomy for esophageal adenocarcinoma) received intravenous infusion of IdU (200 mg/m(2) body surface area; maximum dose, 400 mg) over a 30-minute period; the IdU had a circulation half-life of 8 hours. Tissues were collected at 7, 11, 29, and 67 days after infusion, from regions of healthy esophagus, BE, dysplasia, adenocarcinoma, and healthy stomach; they were analyzed by in situ hybridization, flow cytometry, and immunohistochemical analyses. RESULTS No LRCs were found in dysplasias or adenocarcinomas, but there were significant numbers of LRCs in the base of glands from BE tissue, in the papillae of the basal layer of the esophageal squamous epithelium, and in the neck/isthmus region of healthy stomach. These cells cycled slowly because IdU was retained for at least 67 days and co-labeling with Ki-67 was infrequent. In glands from BE tissues, most cells did not express defensin-5, Muc-2, or chromogranin A, indicating that they were not lineage committed. Some cells labeled for endocrine markers and IdU at 67 days; these cells represented a small population (<0.1%) of epithelial cells at this time point. The epithelial turnover time of the healthy esophageal mucosa was approximately 11 days (twice that of the intestine). CONCLUSIONS LRCs of human esophagus and stomach have many features of stem cells (long lived, slow cycling, uncommitted, and multipotent), and can be found in a recognized stem cell niche. Further analyses of these cells, in healthy and metaplastic epithelia, is required.

Abstract
Recently, extensive data have been published about the safety and efficacy of endoscopic radiofrequency ablation (RFA) of Barrett's esophagus (BE) with early cancer and dysplasia as well as without dysplasia. RFA has been shown to be effective and safe. Circumferential RFA is delivered using the HALO(360+) Ablation System (Covidien, Inc., Mansfield, MA), which consists ofa high-power energy generator, a sizing balloon catheter, and a number of balloon-based ablation catheters with varying outer diameters. Focal RF energy is delivered using the HALO(90) or HALO(60) Ablation Systems (Covidien, Inc., Mansfield, MA), consisting of a radiofrequency energy generator and an endoscope-mounted electrode. Both RFA systems have official approval to be used in the United States, Europe, and other countries for the treatment of BE as well as in patients with gastric antral vascular ectasia and radiation proctopathy. With increasing widespread use of these systems, a full mastery of the equipment and therapeutic technique is essential to maximize eradication rates of BE while maintaining patient safety. A cost-effective patient selection and eradication protocol for RFA is essential to success with this technique in patients with BE. This article will discuss our experience with RFA treatment of BE using the HALO system for effective eradication of Barrett's dysplasia and early Barrett's cancer and review available data especially from the U.S. National Registry.

Abstract
BACKGROUND Barrett's oesophagus is one of the most common pre-malignant lesions in the world. Currently the mainstay of therapy is surgical management of advanced cancer but this has improved the five-year survival very little since the 1980s. As a consequence, improved survival relies on early detection through endoscopic surveillance programmes. Success of this strategy relies on the fact that late-stage pre-malignant lesions or very early cancers can be cured by intervention. Currently there is considerable controversy over which method is best: that is conventional open surgery or endotherapy (techniques involving endoscopy). OBJECTIVES We used data from randomised controlled trials (RCTs) to examine the effectiveness of endotherapies compared with surgery in people with Barrett's oesophagus, those with early neoplasias (defined as high-grade dysplasia (HGD) and those with early cancer (defined as carcinoma in-situ, superficially invasive, early cancer or superficial cancer T-1m (T1-a) and T-1sm (T1-b)). SEARCH METHODS We used the Cochrane highly sensitive search strategy to identify RCTs in MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science, EBMR, Controlled Trials mRCT and ISRCTN, and LILACS, in July and August 2008. The searches were updated in 2009 and again in April 2012. SELECTION CRITERIA Types of studies: RCTs comparing endotherapies with surgery in the treatment of or early cancer. All cellular types of cancer were included (i.e. adenocarcinomas, squamous cell carcinomas and more unusual types) but will be discussed separately. TYPES OF PARTICIPANTS patients of any age and either gender with a histologically confirmed diagnosis of early neoplasia (HGD and early cancer) in Barrett's or squamous lined oesophagus.Types of interventions; endotherapies (the intervention) compared with surgery (the control), all with curative intent. DATA COLLECTION AND ANALYSIS Reports of studies that meet the inclusion criteria for this review would have been analysed using the methods detailed in Appendix 9. MAIN RESULTS We did not identify any studies that met the inclusion criteria. In total we excluded 13 studies that were not RCTs but that compared surgery and endotherapies. AUTHORS' CONCLUSIONS This Cochrane review has indicated that there are no RCTs to compare management options in this vital area, therefore trials should be undertaken as a matter of urgency. The problems with such randomised methods are standardising surgery and endotherapies in all sites, standardising histopathology in all centres, assessing which patients are fit or unfit for surgery and making sure there are relevant outcomes for the study (i.e. long-term survival (over five or more years)) and no progression of HGD.

Abstract
BACKGROUND Endoscopic radiofrequency ablation (RFA) is a promising new treatment of Barrett's esophagus (BE). Adjunctive intra-esophageal pH control with proton pump inhibitors and/or anti-reflux surgery is generally recommended to optimize squamous re-epithelialization after ablation. AIMS The aims of this study were to examine the association between intra-esophageal pH control and RFA outcomes and to identify predictive factors to achieve complete elimination (CE) of BE following RFA. METHODS We retrospectively studied the outcomes of BE patients treated with RFA. Esophageal acid exposure (EAE) was assessed utilizing 24-h pH monitoring on therapy. CE was endoscopically defined as no area suspicious for residual metaplasia following RFA. RESULTS Of 45 patients (33 men; mean age 61.6, mean BE length C4.1 M4.6) examined for EAE, 29 % exhibited moderate-severe EAE despite therapy. Reduction in BE surface area and CE rate were higher in the normal-mild EAE group compared with the moderate-severe EAE group (99 vs. 95 %, p = 0.02; 44 vs. 15 %, p = 0.09, respectively). Using univariate analysis, age, gender, race, aspirin/NSAIDs use, baseline worst histology, baseline BE surface area, and the number or types of RFA had no correlation with CE. By multivariate multiple logistic regression analysis, normal-mild EAE and smaller hiatal hernia were independent factors associated with CE. CONCLUSIONS Effective intra-esophageal pH control is associated with improved RFA outcomes of BE. Normal to mild EAE and smaller hiatal hernia are predictive factors to achieve CE. Given the frequent persistence of acid reflux despite therapy in BE patients, in order to maximize the RFA effects esophageal pH optimization and hernia repair should be considered.

Abstract
BACKGROUND EMR is commonly performed before radiofrequency ablation (RFA) for nodular dysplastic Barrett's esophagus (BE). OBJECTIVE To determine the efficacy and safety of EMR before RFA for nodular BE with advanced neoplasia (high-grade dysplasia [HGD] or intramucosal carcinoma [IMC]). DESIGN Retrospective study. SETTING University of North Carolina Hospitals, from 2006 to 2011. PATIENTS 169 patients with BE with advanced neoplasia: 65 patients treated with EMR and RFA for nodular disease and 104 patients treated with RFA alone for nonnodular disease. INTERVENTIONS EMR, RFA. MAIN OUTCOME MEASUREMENTS Efficacy (complete eradication of dysplasia, complete eradication of intestinal metaplasia, total treatment sessions, RFA treatment sessions), safety (stricture formation, bleeding, and hospitalization). RESULTS EMR followed by RFA achieved complete eradication of dysplasia and complete eradication of intestinal metaplasia in 94.0% and 88.0% of patients, respectively, compared with 82.7% and 77.6% of patients, respectively, in the RFA-only group (P = .06 and P = .13, respectively). The complication rates between the 2 groups were similar (7.7% vs 9.6%, P = .79). Strictures occurred in 4.6% of patients in the EMR-before-RFA group. compared with 7.7% of patients in the RFA-only group (P = .53). LIMITATIONS Retrospective study at a tertiary-care referral center. CONCLUSION In patients treated with EMR before RFA for nodular BE with HGD or IMC, no differences in efficacy and safety outcomes were observed compared with RFA alone for nonnodular BE with HGD or IMC. EMR followed by RFA is safe and effective for patients with nodular BE and advanced neoplasia.

Abstract
BACKGROUND Endoscopic ablation is an accepted standard for neoplasia in Barrett's esophagus (BE). Eradication of all glandular mucosa in the distal esophagus cannot be reliably determined at endoscopy. OBJECTIVE To assess if use of probe-based confocal laser endomicroscopy (pCLE) in addition to high-definition white light (HDWL) could aid in determination of residual BE. DESIGN Prospective, multicenter, randomized, clinical trial. SETTING Academic medical centers. PATIENTS Patients with Barrett's esophagus undergoing ablation. INTERVENTION After an initial attempt at ablation, patients were followed-up either with HDWL endoscopy or HDWL plus pCLE, with treatment of residual metaplasia or neoplasia based on endoscopic findings and pCLE used to avoid overtreatment. MAIN OUTCOME MEASUREMENTS The proportion of optimally treated patients, defined as those with residual BE who were treated and had complete ablation plus those without BE who were not treated and had no evidence of disease at follow-up. RESULTS The study was halted at the planned interim analysis based on a priori criteria. After enrollment was halted, all patients who had been randomized were followed to study completion. Among the 119 patients with follow-up, there was no difference in the proportion of patients achieving optimal outcomes in the two groups (15/57, 26% for HDWL; 17/62, 27% with HDWL + pCLE). Other outcomes were similar in the two groups. LIMITATIONS The study was closed after the interim analysis due to low conditional power resulting from lack of difference between groups as well as higher-than-expected residual Barrett's esophagus in both arms. CONCLUSION This study yields no evidence that the addition of pCLE to HDWL imaging for detection of residual Barrett's esophagus or neoplasia can provide improved treatment.

Abstract
UNLABELLED Endoscopic resection (EMR) and radiofrequency ablation (RFA) form part of the treatment of Barrett's oesophagus (BO), dysplasia, superficial adenocarcinoma (OAC) associated with BO. PATIENTS AND METHODS Between June 2008 and April 2011, 34 patients underwent treatment with RFA (HALO system(®)), in a tertiary centre. For the study, patients were divided into two groups. Group 1 (16 patients of average 60 years old; 14 men, two women) received EMR and RFA. Group 2 (18 patients averaging 59 years age; 14 men, four women) received RFA without EMR in the year preceding the RFA. RESULTS In group 1, high grade dysplasia (HGD) was eradicated in 12 cases (92%), low grade dysplasia (LGD) in three cases (100%). Complete response occurred in nine cases (56%), partial response in 100% of cases. Mean follow-up was 15 months. In group 2, HGD was eradicated in one patient (100%), LGD in three patients (64%). A complete response was achieved in eight patients, partial response in four cases (77%). Mean follow-up was 10 months. The complication rate for groups 1 and 2 was of 18% and 10% respectively. No complication prevented completion of treatment or continued monitoring. Recurrence was evaluated to 5% in both groups. CONCLUSION RFA associated with EMR is feasible, offering probably better results and a very important advantage: a more complete histology before follow-up. Our results show effective treatment of BO and associated dysplasia with a low rate of complication. Nevertheless, when new techniques of BO ablation are used, the need to obtain histology before treatment should not be forgotten.

Abstract
BACKGROUND Radiofrequency ablation (RFA) is an endoscopic technique used to eradicate Barrett's esophagus (BE). However, such ablation can commonly lead to neosquamous epithelium overlying residual BE glands not visible by conventional endoscopy and may evade detection on random biopsy samples. OBJECTIVE To demonstrate the capability of endoscopic 3-dimensional optical coherence tomography (3D-OCT) for the identification and characterization of buried glands before and after RFA therapy. DESIGN Cross-sectional study. SETTING Single teaching hospital. PATIENTS Twenty-six male and 1 female white patients with BE undergoing RFA treatment. INTERVENTIONS 3D-OCT was performed at the gastroesophageal junction in 18 patients before attaining complete eradication of intestinal metaplasia (pre-CE-IM group) and in 16 patients after CE-IM (post-CE-IM group). MAIN OUTCOME MEASUREMENTS Prevalence, size, and location of buried glands relative to the squamocolumnar junction. RESULTS 3D-OCT provided an approximately 30 to 60 times larger field of view compared with jumbo and standard biopsy and sufficient imaging depth for detecting buried glands. Based on 3D-OCT results, buried glands were found in 72% of patients (13/18) in the pre-CE-IM group and 63% of patients (10/16) in the post-CE-IM group. The number (mean [standard deviation]) of buried glands per patient in the post-CE-IM group (7.1 [9.3]) was significantly lower compared with the pre-CE-IM group (34.4 [44.6]; P = .02). The buried gland size (P = .69) and distribution (P = .54) were not significantly different before and after CE-IM. LIMITATIONS A single-center, cross-sectional study comparing patients at different time points in treatment. Lack of 1-to-1 coregistered histology for all OCT data sets obtained in vivo. CONCLUSION Buried glands were frequently detected with 3D-OCT near the gastroesophageal junction before and after radiofrequency ablation.

Abstract
Radiofrequency ablation (RFA) has gained popularity as treatment for Barrett's esophagus. Inclusive series of patients from initiation of our Barrett's Therapy Program were studied. Review of patients undergoing RFA for Barrett's was performed from September 2008 to May 2011. Patients' outcomes were recorded and analyzed using standard statistical methods. Seventy patients were treated. Average age was 61 (28-70); 80 per cent were male. Seventy-four per cent had dysplasia; 44 low-grade and eight high-grade. A total of 75.7 per cent of patients had long and 24.3 per cent had short segment Barrett's. Procedures per patient ranged from one to seven. Number of treatments in long- and short-segment groups were not different (P = 0.11). The maximum number of treatments in the short-segment group was five with a median of three (44.3%). For long segment, the maximum of RFA procedures was seven, with a median of three (30.8%). Average procedure time was 20.8 minutes for long and 17.9 minutes for short segment. Mean follow-up was 16.1 (2-38) months. Complete response was accomplished in 81 per cent. There were 93.3 per cent of complete responders in the short-segment group versus 75 per cent in the long (P = 0.24). Complications included dysphagia (1), transient chest and cervical pain (1), and abdominal pain (1). Comparing the first 25 per cent of the RFA procedures to the later 75 per cent or first 50 per cent to second 50 per cent, there was no difference in operative time or complications. Two patients recurred, both in the long-segment group. RFA is a safe and effective means to eradicate Barrett's. By measure of treatment time, complication rate, and efficacy of therapy, there is minimal or no "learning curve" for experienced endoscopists.

Abstract
BACKGROUND Oesophagectomy is a complex procedure associated with a significant morbidity and mortality rate. There is very little published data from New Zealand, with no published data from a non-Tertiary New Zealand hospital. We aimed to evaluate the outcomes of oesophagectomy at a single provincial hospital in New Zealand. METHOD Retrospective review of clinical records of all patients who underwent oesophagectomy at Palmerston North Hospital (a level II provincial New Zealand public hospital) between 1993 and 2010 was performed. Demographic data, operative details, postoperative recovery parameters, survival data, pathological data, and details of adjuvant treatment were collected. RESULTS Data from all 68 patients who underwent oesophagectomy were included. Mean age was 63.6 plus or minus 10.9 years, and 69% of patients were male. Mean operating time was 438.37 plus or minus 101.8 min, and mean intraoperative blood loss was 934.5 plus or minus 790.2 ml. Median intensive care unit stay was 7 (1-29) days, and total day stay was 17.5 (4-60) days. Tracheostomy was performed in 20 patients (29.4%). Anastomotic leak occurred in 7 patients (10.3%), chylothorax in 6 patients (8.8%) and cardiopulmonary complications in 34 patients (50.0%). The all cause in-hospital mortality rate was 4.4%. Overall survival at 30 days was 98.5%, at 1 year was 78.3% and at 5 years was 30.3%. CONCLUSION Survival outcomes of oesophagectomy in this provincial New Zealand hospital are comparable to published series from national and international tertiary centres.

Abstract
BACKGROUND AND AIMS Endoscopic therapies for Barrett's esophagus (BE) associated dysplasia, particularly radiofrequency ablation (RFA), are popular alternatives to surgery. The effect of such therapies on dysplastic stem/progenitor cells (SPC) is unknown. Recent studies suggest that AKT phosphorylation of β-Catenin occurs in SPCs and may be a marker of activated SPCs. We evaluate the effect of RFA in restoring AKT-mediated β-Catenin signaling in regenerative epithelium. METHODS Biopsies were taken from squamous, non-dysplastic BE, dysplastic BE and esophageal adenocarcinoma (EAC). Also, post-RFA, biopsies of endoscopically normal appearing neosquamous epithelium were taken at 3, 6, and 12 months after successful RFA. Immunohistochemistry and Western blot analysis was performed for Pβ-Catenin(552) (Akt-mediated phosphorylation of β-Catenin), Ki-67 and p53. RESULTS There was no difference in Pβ-Catenin552 in squamous, GERD, small bowel and non-dysplastic BE. There was a fivefold increase in Pβ-Catenin(552) in dysplasia and EAC compared to non-dysplastic BE (P < 0.05). Also, there was a persistent threefold increase in Pβ-Catenin(552) in neosquamous epithelium 3 months after RFA compared to native squamous epithelium (P < 0.05) that correlated with increased Ki-67. Six months after RFA, Pβ-Catenin(552) and Ki-67 are similar to native squamous epithelium. CONCLUSIONS Enhanced AKT-mediated β-Catenin activation is seen in BE-associated carcinogenesis. Three months after RFA, squamous epithelial growth from SPC populations exhibited increased levels of Pβ-Catenin(552). This epithelial response becomes quiescent at 6 months after RFA. These data suggest that elevated Pβ-Catenin(552) after RFA denotes a repair response in the neosquamous epithelium 3 months post-RFA.

Abstract
INTRODUCTION Barrett's esophagus (BE) is a well established precursor of esophageal adenocarcinoma. Both, surveillance and therapeutic strategies have been proposed over the years. Recent deve-lopment of endoscopic radiofrequency ablation (RFA) brought new perspectives in the treatment of BE, with excellent initial results. METHODS The study of 40 pts with macroscopically visible BE on endoscopy and biopsy proven goblet cells presence, was conducted from January 2010 until March 2012. In all pts a complete symptomatic, endoscopic and manometric evaluation was performed. Initially RFA HALO 90 and 360 were performed in 28 and 12 pts respectively. Repeated treatments were conducted in 7 pts. The overall number was 50, while the mean number of RFA procedures per patient was 1.25. RESULTS The mean circumferential length and maximal extent of BE were 1.61 and 3.29 cm respectively. We did not encounter esophageal perforation or hemorrhage during the procedure. Complications were transient short-term retrosternal pain (23 pts) and dysphagia (11 pts). Three months after the RFA mean values of cumulative symptom and heartburn score dropped significantly (p < 0.05). Functional diagnostics did not disclose any statistically significant decrease of lower esophageal sphincter pressure or esophageal body contraction amplitudes. One year foIlow-up was obtained in 26 pts and revealed a complete macroscopically visible BE eradication. So far, in 19 pts a laparoscopic Nissen fundoplication was performed up to 3 months after complete RFA BE eradication. CONCLUSION HALO RFA procedure is safe and very effective in the treatment of pts with BE, does not lead to esophageal function impairment, and produces no long term and serious side effects.

AIM The aim of this study was to demonstrate the efficacy of laparoscopic antireflux surgery in controlling Barrett's esophagus progression, through functional study. METHODS Between January 2008 and December 2009, 21 patients with a preoperative diagnosis of Barrett's esophagus underwent Nissen-Rossetti fundoplication. RESULTS All patients underwent preoperatively a 24-hour pH-metry (100%). Twenty patients (95.2%) had postoperative pH monitoring at six months, 16 patients at 12 months (76.2%), eight at 24 months (57.14%). Median De Meester and Johnson score was preoperatively 18.55 (range 8.6-179.7), at six months 7.65 (range 6.4-13), at 12 months 7.5 (range 6.4-14.2), at 24 months 11.95 (range 6.4-20.6). CLE was still present in 18 patients (18/21, 85.7%), but no patient developed dysplasia or esophageal adenocarcinoma. Two patients with gastric- and one patient with intestinal metaplasia showed complete regression at 12 and 24 months after fundoplication (3/21, 14.3%). Symptom control alone does not manage acid reflux in patients with Barrett's esophagus after surgery, and postoperative 24-hour pH-metry confirms acid reflux abolition. A persistent reflux is more likely to develop cancer than in monitored patients. CONCLUSION Only the presence of intact and effective anti-reflux wrap guarantees protection of the esophagus against CLE progression or its regression. Functional study after surgery identifies patients with Barrett's progression risk.

Abstract
INTRODUCTION Gastrointestinal leak is a dreaded complication after esophagectomy. Conventional treatments for leak include conservative therapy, surgical reoperation, and even complete gastrointestinal (GI) diversion. The aim of this study was to evaluate the impact of endoluminal stenting in the management of esophagogastric leak after esophagectomy. METHODS Data on 18 (11.3%) of 160 patients who developed postoperative leaks after minimally invasive esophagectomy were reviewed. Indications for esophagectomy included carcinoma (n = 14), Barrett's with high-grade dysplasia (n = 3), and benign stricture (n = 1). Neoadjuvant therapy was used in 57.1% of patients with carcinoma. The first nine patients underwent conventional treatments for leak whereas the latter nine patients underwent endoscopic esophageal covered stenting as primary therapy. There were 5 cervical and 13 intrathoracic anastomotic leaks. Main outcome measures included patient characteristics, types of treatment, length of hospital stay, morbidity, and mortality. RESULTS Subjects were 16 males and 2 females with a mean age of 66 years. In the conventional treatment group, leaks were treated with neck drainage (n = 4), GI diversion (n = 2), and thoracoscopic drainage with or without repair or T-tube placement (n = 3). In the endoscopy group, all leaks were treated with endoscopic covered stenting with or without percutaneous drainage (n = 9). Control of leaks occurred in 89% of patients in the conventional treatment group vs. 100% of patients in the endoscopic stenting group. Three patients in the conventional treatment group (33%) required esophageal diversion compared to none of the patients in the endoscopy group. The 60-day or in-hospital mortality was 0% for both groups. CONCLUSION In our clinical practice, there has been a shift in the management of esophagogastric anastomotic leaks to nonsurgical therapy using endoscopic esophageal covered stenting. Endoluminal stenting is a safe and effective alternative in the management of GI leaks.

Abstract
Barrett's esophagus is a columnar metaplasia conferring an increased risk of adenocarcinoma development. Evidence suggests that this increased risk is due to field cancerization - the formation of histologically undistinguishable field of clonally derived, mutant cells within the Barrett's segment. Field cancerization can occur prior to both dysplasia and invasive neoplasia and potentially provides a mechanism for the development of multifocal and metachronous tumors. In the gastrointestinal tract, mutant clones spread predominately by crypt fission; the same is likely to be true in Barrett's lesions. Epithelial interactions in the form of cooperation or competition between epithelial clones, as well as with stromal cells, may further drive clone growth. Field cancerization is a clinically relevant phenomenon, knowledge of which could influence the size of resection margins to enhance prognosis after curative surgery, as well as provide a rationale for the development of effective biomarkers for neoplasia risk in Barrett's esophagus. This may provide a foundation for streamlined surveillance programs to prevent the development of invasive tumors.

Abstract
BACKGROUND EMR for early neoplastic Barrett's esophagus is gaining favor over esophagectomy. Esophageal stricture development has been reported as a common complication of EMR, photodynamic therapy, and combination endoscopic therapy. OBJECTIVE To determine clinical and procedural predictors of symptomatic stricture formation after EMR. DESIGN Retrospective analysis. SETTING Tertiary-care referral university hospital. PATIENTS Data were retrospectively reviewed on 73 patients at our institution who underwent EMR monotherapy for Barrett's esophagus with high-grade dysplasia or intramucosal cancer since January 2006. INTERVENTION EMR. MAIN OUTCOME MEASUREMENTS Symptomatic esophageal stricture formation. RESULTS Symptomatic esophageal stricture formation was noted in 24.7% of patients undergoing EMR. Stricture formation on univariate analysis was associated with percentage of circumference of esophageal lumen resected, total pieces resected, number of EMR sessions, and tobacco use. A threshold effect was found at 50% of esophageal circumference resected (66.7% vs 27.2% developed strictures above and below the threshold, respectively; P = .004). A 25-pack-year or greater history of tobacco use had a threshold effect on esophageal stricture formation (77.8% vs 7.2% developed strictures above and below the threshold, respectively; P = .02). In multivariate analysis, resection of >50% of the circumference was strongly associated with stricture formation (odds ratio [OR] 4.17; 95% confidence interval [CI], 1.27-13.7). A 25-pack-year or greater history of tobacco use also trended toward stricture formation (OR 3.33; 95% CI, 0.929-12.1). LIMITATIONS Retrospective design, sample size. CONCLUSION Resection of at least 50% of the esophageal mucosal circumference is strongly associated with stricture formation. Patients with strong histories of tobacco use also may be more likely to develop esophageal strictures following EMR.
