Abstract
BACKGROUND & AIMS Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC). Endoscopic eradication therapy (EET) can be effective in eradicating BE and related neoplasia and has greater risk of harms and resource use than surveillance endoscopy. This clinical practice guideline aims to inform clinicians and patients by providing evidence-based practice recommendations for the use of EET in BE and related neoplasia. METHODS The Grading of Recommendations Assessment, Development and Evaluation framework was used to assess evidence and make recommendations. The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients, conducted an evidence review, and used the Evidence-to-Decision Framework to develop recommendations regarding the use of EET in patients with BE under the following scenarios: presence of (1) high-grade dysplasia, (2) low-grade dysplasia, (3) no dysplasia, and (4) choice of stepwise endoscopic mucosal resection (EMR) or focal EMR plus ablation, and (5) endoscopic submucosal dissection vs EMR. Clinical recommendations were based on the balance between desirable and undesirable effects, patient values, costs, and health equity considerations. RESULTS The panel agreed on 5 recommendations for the use of EET in BE and related neoplasia. Based on the available evidence, the panel made a strong recommendation in favor of EET in patients with BE high-grade dysplasia and conditional recommendation against EET in BE without dysplasia. The panel made a conditional recommendation in favor of EET in BE low-grade dysplasia; patients with BE low-grade dysplasia who place a higher value on the potential harms and lower value on the benefits (which are uncertain) regarding reduction of esophageal cancer mortality could reasonably select surveillance endoscopy. In patients with visible lesions, a conditional recommendation was made in favor of focal EMR plus ablation over stepwise EMR. In patients with visible neoplastic lesions undergoing resection, the use of either endoscopic mucosal resection or endoscopic submucosal dissection was suggested based on lesion characteristics. CONCLUSIONS This document provides a comprehensive outline of the indications for EET in the management of BE and related neoplasia. Guidance is also provided regarding the considerations surrounding implementation of EET. Providers should engage in shared decision making based on patient preferences. Limitations and gaps in the evidence are highlighted to guide future research opportunities.

Abstract
BACKGROUND AND AIMS Endoscopic eradication therapy for Barrett's esophagus (BE)-related neoplasia is increasingly being performed at tertiary and community centers. While it has been suggested that these patients should be evaluated at expert centers, the impact of this practice has not been evaluated. We aimed to assess the impact of referral of BE-related neoplasia patients to expert centers by assessing the proportion of patients with change in pathological diagnosis and visible lesions detected. METHODS Multiple databases were searched until December 2021 for studies of patients with BE referred from the community to expert center. The proportions of pathology grade change and newly detected visible lesions at expert centers were pooled using a random-effects model. Subgroup analyses were performed based on baseline histology and other relevant factors. RESULTS Twelve studies were included (1630 patients). The pooled proportion of pathology grade change after expert pathologist review was 47% (95% CI 34-59%) overall and 46% (95% CI 31-62%) among patients with baseline low-grade dysplasia. When upper endoscopy was repeated at an expert center, the pooled proportion of pathology grade change was still high 47% (95% 26-69%) overall and 40% (95% CI 34-45%) among patients with baseline LGD. The pooled proportion of newly detected visible lesions was 45% (95% CI 28-63%) and among patients referred with LGD was 27% (95% CI 22-32%). CONCLUSION An alarmingly high proportion of newly detected visible lesions and pathology grade change were found when patients were referred to expert centers supporting the need for centralized care for BE-related neoplasia patients.

Predictive factors of radiofrequency ablation failure in the treatment of dysplastic Barrett's esophagus. Clin Res Hepatol Gastroenterol 2023; 47:102065.

Abstract
INTRODUCTION Radiofrequency ablation (RFA) has become the recommended endoscopic treatment for flat dysplastic Barrett's esophagus. However, the outcomes of this treatment are variable across European countries. Our aim was to report the results of a French high-volume center, and to investigate factors associated with treatment failure. METHODS We conducted a single-center retrospective study from a prospectively collected database from 2011 to 2020, including all consecutive patients treated with RFA for flat dysplastic Barrett's esophagus. The primary endpoint was the failure rate of esophageal radiofrequency treatment, defined as either persistence of intestinal metaplasia at the end of treatment, or neoplastic progression during RFA. RESULTS 96 patients treated with a median of four RFA sessions for a mean C5M6 Barrett's esophagus were included in the analysis. Complete eradication of intestinal metaplasia and dysplasia were achieved in 59% and 79% of patients, respectively, resulting in a treatment failure rate of 41%. Ten patients experienced neoplastic progression during treatment. We recorded 14% of post-RFA esophageal strictures, all successfully treated by endoscopic dilatation. Univariate analysis identified the length of Barrett's esophagus and the absence of hiatal hernia as predictive factors for treatment failure, however not confirmed in multivariate analysis. CONCLUSION In our experience, RFA of flat dysplastic Barrett's esophagus had a 41% treatment failure rate. The length of the Barrett's segment might be associated with treatment failure. Although our results confirm a role for RFA in the management of dysplastic Barrett's esophagus, the treatment failure rate was higher than expected. This suggest that endoscopists, even in high-volume centers, should receive specific training in RFA.

Abstract
Barrett's esophagus (BE) is a common condition associated with chronic gastroesophageal reflux disease. BE is the only known precursor to esophageal adenocarcinoma, a highly lethal cancer with an increasing incidence over the last 5 decades. These revised guidelines implement Grading of Recommendations, Assessment, Development, and Evaluation methodology to propose recommendations for the definition and diagnosis of BE, screening for BE and esophageal adenocarcinoma, surveillance of patients with known BE, and the medical and endoscopic treatment of BE and its associated early neoplasia. Important changes since the previous iteration of this guideline include a broadening of acceptable screening modalities for BE to include nonendoscopic methods, liberalized intervals for surveillance of short-segment BE, and volume criteria for endoscopic therapy centers for BE. We recommend endoscopic eradication therapy for patients with BE and high-grade dysplasia and those with BE and low-grade dysplasia. We propose structured surveillance intervals for patients with dysplastic BE after successful ablation based on the baseline degree of dysplasia. We could not make recommendations regarding chemoprevention or use of biomarkers in routine practice due to insufficient data.

Abstract
Background and study aims Transoral incisionless fundoplication (TIF) is a safe and effective minimally invasive endoscopic technique for treating gastroesophageal reflux disease (GERD). The learning curve for this technique has not been reported. We studied the learning curve for TIF when performed by a gastroenterologist by identifying the threshold number of procedures needed to achieve consistent technical success or proficiency (consistent creation of TIF valve ≥ 270 degrees in circumference, ≥ 2 cm long) and efficiency after didactic, hands-on and case observation experience. Patients and methods We analyzed prospectively collected data from patients who had TIF performed by a single therapeutic endoscopist within 17 months after basic training. We determined thresholds for procedural learning using cumulative sum of means (CUSUM) analysis to detect changes in achievement rates over time. We used breakpoint analysis to calculate procedure metrics related to proficiency and efficiency. Results A total of 69 patients had 72 TIFs. The most common indications were refractory GERD (44.7 %) and proton pump inhbitor intolerance (23.6 %). Proficiency was achieved at the 18 th to 20 th procedure. The maximum efficiency for performing a plication was achieved after the 26 th procedure, when mean time per plication decreased to 2.7 from 5.1 minutes (P < 0.0001). TIF procedures time varied until the 44 th procedure, after which it decreased significantly from 53.7 minutes to 39.4 minutes (P < 0.0001). Conclusions TIF can be safely, successfully, and efficiently performed in the endoscopy suite by a therapeutic endoscopist. The TIF learning curve is steep but proficiency can be achieved after a basic training experience and 18 to 20 independently performed procedures.

Abstract
BACKGROUND Radiofrequency ablation (RFA) has been increasingly accepted as an alternative to surgery in the treatment of symptomatic benign thyroid nodules. However, the learning curve of thyroid RFA has yet to be defined. We hypothesized a temporal relationship between proficiency of the skill and midterm volume reduction. METHODS Consecutive patients who underwent RFA and had at least a six-month follow-up were identified from an institutional database. The cumulative sum (CUSUM) analysis was applied to visualize the learning curve on the adjusted volume reduction rate (VRR). RESULTS A total of 102 nodules in 93 patients were included in the analysis. Linear regression revealed that nodule composition was the main predictor of the VRR. The composition-adjusted VRR increased with the chronological treatment order. The series was divided into three phases based on inflection points of the CUSUM analysis: the initial learning phase (case 1-20), consolidation phase (case 21-65), and proficiency phase (case 66-102). In the later phase, more solid nodules were treated, power output used by the operator was higher, and RFA treatment time was longer. CONCLUSION The treatment efficiency of thyroid RFA was associated with technical proficiency, suggesting the presence of a learning curve effect.

Abstract
Endoscopic eradication therapy for Barrett's esophagus has been established as an effective management strategy for patients with Barrett's esophagus with dysplasia and early esophageal cancer. Among the endoscopic therapies, ablation techniques such as radiofrequency ablation and cryoablation are effective primary treatment interventions with acceptable low complication rates forming the spectrum of a multimodal approach. Appropriate selection of patients, high-definition endoscopic evaluation, and dedicated histological assessment are important cornerstones to help navigate to the best effective treatment method. Carefully structured surveillance programs and preventive measures will be needed to provide long-term durability for maintaining complete remission.

Abstract
OBJECTIVE Due to an annual progression rate of Barrett's oesophagus (BO) with low-grade dysplasia (LGD) between 9% and 13% per year endoscopic ablation therapy is preferred to surveillance. Since this recommendation is based on only one randomised trial, we aimed at checking these results by another multicentre randomised trial with a similar design. DESIGN A prospective randomised study was performed in 14 centres comparing radiofrequency ablation (RFA) (maximum of 4 sessions) to annual endoscopic surveillance, including patients with a confirmed diagnosis of BO with LGD. Primary outcome was the prevalence of LGD at 3 years. Secondary outcomes were the prevalence of LGD at 1 year, the complete eradication of intestinal metaplasia (CE-IM) at 3 years, the rate of neoplastic progression at 3 years and the treatment-related morbidity. RESULTS 125 patients were initially included, of whom 82 with confirmed LGD (76 men, mean age 62.3 years) were finally randomised, 40 patients in the RFA and 42 in the surveillance group. At 3 years, CE-IM rates were 35% vs 0% in the RFA and surveillance groups, respectively (p<0.001). At the same time, the prevalence LGD was 34.3% (95% CI 18.6 to 50.0) in the RFA group vs 58.1% (95% CI 40.7 to 75.4) in the surveillance group (OR=0.38 (95% CI 0.14 to 1.02), p=0.05). Neoplastic progression was found in 12.5% (RFA) vs 26.2% (surveillance; p=0.15). The complication rate was maximal after the first RFA treatment (16.9%). CONCLUSION RFA modestly reduced the prevalence of LGD as well as progression risk at 3 years. The risk-benefit balance of endoscopic ablation therapy should therefore be carefully weighted against surveillance in patients with BO with confirmed LGD. TRIAL REGISTRATION NUMBER NCT01360541.

Abstract
BACKGROUND AND AIMS Endoscopic resections and radiofrequency ablation (RFA) are the established treatments for Barrett's-associated dysplasia and early esophageal neoplasia. The UK RFA Registry collects patient outcomes from 24 centers treating patients in the United Kingdom and Ireland. Learning curves for treatment of Barrett's dysplasia and the impact of center caseload on patient outcomes is still unknown. METHODS We examined outcomes of 678 patients treated with RFA in the UK Registry using risk-adjusted cumulative sum control chart (RA-CUSUM) analysis to identify change points in complete resolution of intestinal metaplasia (CR-IM) and complete resolution of dysplasia (CR-D) outcomes. We compared outcomes between those treated at high-volume (>100 enrolled patients), medium-volume (51-100), and low-volume (<50) centers. RESULTS There was no association between center volume and CR-IM and CR-D rates, but recurrence rates were lower in high-volume versus low-volume centers (log rank P = .001). There was a significant change point for outcomes at 12 cases for CR-D (reduction from 24.5% to 10.4%; P < .001) and at 18 cases for CR-IM (30.7% to 18.6%; P < .001) from RA-CUSUM curve analysis. CONCLUSION Our data suggest that 18 supervised cases of endoscopic ablation may be required before competency in endoscopic treatment of Barrett's dysplasia can be achieved. The difference in outcomes between a high-volume and low-volume center does not support further centralization of services to only high-volume centers.

Abstract
PURPOSE OF REVIEW Barrett's esophagus (BE) is a premalignant condition of the esophagus associated with an increased risk for esophageal adenocarcinoma (EAC). Radiofrequency ablation (RFA) is a safe and effective first-line treatment for dysplastic BE and early stage EAC. This report reviews clinically relevant evidence published over the last 3 years regarding RFA for BE. RECENT FINDINGS Our use of this technology has simultaneously gone too far, in that many patients who may not derive a benefit from these treatments are receiving them, and not far enough, in that many patients who would be eligible for ablative therapy never undergo screening exams to assess them for dysplastic BE, or do not have endoscopic therapy considered part of the treatment of superficial invasive cancer. Research to better identify patients with BE, risk stratify those patients, improve the quality of RFA treatment, and inform surveillance practices has the potential to optimize the benefit of RFA, and minimize the harms, costs, and risks.

Abstract
Radiofrequency ablation (RFA) is very effective for eradication of flat Barrett’s mucosa in dysplastic Barrett’s esophagus after endoscopic resection of raised lesions. However, in a minority of the time, RFA may be ineffective at eradication of the Barrett’s mucosa. Achieving complete eradication of intestinal metaplasia can be challenging in these patients. This review article focuses on the management of patients with dysplastic Barrett’s esophagus refractory to RFA therapy. Management strategies discussed in this review include optimizing the RFA procedure, optimizing acid suppression (with medical, endoscopic, and surgical management), cryotherapy, hybrid argon plasma coagulation, and EndoRotor resection.

Abstract
INTRODUCTION Endoscopic therapy for the management of patients with Barrett's oesophagus (BE) neoplasia has significantly developed in the past decade; however, significant variation in clinical practice exists. The aim of this project was to develop expert physician-lead quality indicators (QIs) for Barrett's endoscopic therapy. METHODS The RAND/UCLA Appropriateness Method was used to combine the best available scientific evidence with the collective judgement of experts to develop quality indicators for Barrett's endotherapy in four subgroups: pre-endoscopy, intraprocedure (resection and ablation) and postendoscopy. International experts, including gastroenterologists, surgeons, BE pathologist, clinical nurse specialist and patient representative, participated in a three-round process to develop 15 QIs that fulfilled the RAND/UCLA definition of appropriateness. RESULTS 17 experts participated in round 1 and 20 in round 2. Of the 24 proposed QIs in round 1, 20 were ranked as appropriate (put through to round 2) and 4 as uncertain (discarded). At the end of round 2, a final list of 15 QIs were scored as appropriate. CONCLUSIONS This UK national consensus project has successfully developed QIs for patients undergoing Barrett's endotherapy. These QIs can be used by service providers to ensure that all patients with BE neoplasia receive uniform and high-quality care.

Abstract
Background and aim: Clinical guidelines recommend endoscopy surveillance at given intervals or endoscopic therapy for Barrett's esophagus with low-grade dysplasia (LGD) and high-grade dysplasia (HGD). Whether these guidelines are followed in clinical practice is unknown and was assessed in this study. Methods: This nationwide Swedish cohort study included patients with Barrett's esophagus with histologically verified LGD or HGD from 50 centers in 2006-2013. These patients were followed up using nationwide registers. Adherence to clinical guidelines was explored. Eight potential risk factors for deviation from guidelines were assessed using multivariable logistic regression, providing adjusted odds ratios (OR) with 95% confidence intervals (95%CI). Results: Among 211 patients with Barrett's esophagus (mean age 67.0 years, standard deviation 9.7 years, 81% male), 71% had LGD and 29% had HGD. During median 3.9 years of follow-up, 84% underwent a follow-up endoscopy, 17% received endoscopic therapy and 8% underwent esophagectomy. The clinical management deviated from guidelines in 60% of all patients (69% in LGD and 39% in HGD), which was mainly due to under-surveillance (86%). Risk factors for deviation from guidelines were LGD compared to HGD (OR 3.4, 95%CI 1.7-6.8), longer Barrett's segment length (OR 2.0, 95%CI 1.0-3.9, comparing ≥3 cm with <3 cm), and treatment at gastroenterology compared to surgery departments (OR 2.3, 95%CI 1.2-4.4). Age, sex, calendar period and university hospital status were not associated with deviation from surveillance guidelines. Conclusions: Adherence to guidelines for dysplastic Barrett's esophagus is poor, particularly for LGD. Efforts to implement clinical guideline recommendations are needed.

Abstract
BACKGROUND Although esophagogastroduodenoscopy (EGD) is usually the first procedure trainees learn, it is not known whether the involvement of a trainee affects the procedure's complication rate, a key quality and safety indicator. The purpose of this study was to determine whether the complication rate of fellow-performed upper endoscopy differs from that of attending gastroenterologists, and whether that difference varies with the level of training. METHODS Emergency room visits within 14 days of an outpatient EGD deemed to be probably or definitely related to the EGD were categorized as complications. Complication rates were calculated for attending- and trainee-performed gastrointestinal endoscopies, the latter stratified by level of training. RESULTS Forty-five attendings and 43 fellows performed 21,899 EGDs during the study period. There were 43 complications (1.96 per 1000 EGDs). Procedures performed by any fellow were more likely to have a complication than those performed by an attending (odds ratio [OR] 2.3, 95% confidence interval [CI] 1.17-4.6). This difference was driven by a higher rate of complications among fellows who had completed general gastroenterology training and were in advanced training (OR 3.8, 95%CI 1.76-8.04); all of these complications involved trainees in interventional endoscopy. Fellows in any year of general gastroenterology training were not more likely to cause complications than attendings. CONCLUSIONS The rate of complications from EGDs performed by fellows in their general gastroenterology training does not differ from that of attending endoscopists. The complication rate of advanced trainees exceeded that of attendings, but this is likely to be attributable to the higher-risk interventions undertaken by fellows in interventional endoscopy.

Abstract
BACKGROUND AND AIMS Endoscopic resection (ER) is safe and effective for Barrett's esophagus (BE) containing high-grade dysplasia (HGD) or mucosal adenocarcinoma (T1A). The risk of metachronous neoplasia is reduced by ablation of residual BE by using radiofrequency ablation (RFA) or argon plasma coagulation (APC). These have not been compared directly. We aimed to recruit up to 100 patients with BE and HGD or T1A confirmed by ER over 1 year in 6 centers in a randomized pilot study. METHODS Randomization was 1:1 to RFA or APC (4 treatments allowed at 2-month intervals). Recruitment, retention, dysplasia clearance, clearance of benign BE, adverse events, healthcare costs, and quality of life by using EQ-5D, EORTC QLQ-C30, or OES18 were assessed up to the end of the trial at 12 months. RESULTS Of 171 patients screened, 76 were randomized to RFA (n = 36) or APC (n = 40). The mean age was 69.7 years, and 82% were male. BE was <5 cm (n = 27), 5 to 10 cm (n = 45), and >10 cm (n = 4). Sixty-five patients completed the trial. At 12 months, dysplasia clearance was RFA 79.4% and APC 83.8% (odds ratio [OR] 0.7; 95% confidence interval [CI], 0.2-2.6); BE clearance was RFA 55.8%, and APC 48.3% (OR 1.4; 95% CI, 0.5-3.6). A total of 6.1% (RFA) and 13.3% (APC) had buried BE glands. Adverse events (including stricture rate after starting RFA 3/36 [8.3%] and APC 3/37 [8.1%]) and quality of life scores were similar, but RFA cost $27491 more per case than APC. CONCLUSION This pilot study suggests similar efficacy and safety but a cost difference favoring APC. A fully powered non-inferiority trial is appropriate to confirm these findings. (Clinical trial registration number: NCT01733719.).

Abstract
BACKGROUND Image-guided microwave ablation (MWA) is a technically demanding procedure, involving advanced visual-spatial perception skills. This study sought to create and evaluate a low-cost model and training curriculum for open ultrasound-guided liver tumor MWA. METHODS Simulated tumors were created, implanted into bovine livers, and visualized by ultrasound. A high-fidelity abdominal model was constructed, with a total cost of $30. Experienced physicians in MWA performed simulated ablations and evaluated the model. Expert performance metrics were established and served as targets for our training curriculum. These included time, number of passes, number of repositionings, and percentage of tumor ablated. Next, 8 novice trainees completed our deliberate practice curriculum. Participants' performances were recorded throughout. RESULTS Physicians completed a structured feedback questionnaire rating the model's realism and training utility at 8/10 and 10/10, respectively. Tumors appeared hyperechoic and were clearly visualized on ultrasound. Trainees performed a total of 32 ablations. Our trainees' performance improved significantly in all outcomes of interest in the postcurriculum ablations compared to precurriculum ablations. CONCLUSION We have created a cost-effective, high-fidelity model of MWA, with a deliberate practice curriculum. Trainees can practice to proficiency with clear target metrics prior to participating in clinical cas.

Abstract
BACKGROUND & AIMS Radiofrequency ablation (RFA) is effective treatment for Barrett's esophagus (BE). However, some patients have recurrence after complete eradication of intestinal metaplasia (CEIM). We investigated the incidence of and factors associated with BE recurrence, with or without neoplasia, after RFA and CEIM using data from the national Veterans Affairs (VA) healthcare system. METHODS We performed a retrospective cohort study of Veterans with BE treated by RFA from 2005 through 2016 with follow-up endoscopy. Subjects were followed until BE recurrence, neoplasia, death until October 2016. CEIM, BE recurrence, and factors associated with recurrence were identified by review of medical records. We calculated incidence rates of BE recurrence, with and without neoplasia, after CEIM and identified predictors using Cox proportional hazards models. RESULTS We identified 430 Veterans with BE who were treated with RFA; of these 337 achieved CEIM (78.4%). Most were men (98.6%), White (83.7%), and 66.0% had baseline dysplasia. Of those with CEIM, 98 patients (29.1%) had recurrence of BE during a total 906.0 patient-years of follow-up (median 1.9 years) after CEIM (incidence, 10.8%/patient-year). Dysplasia developed in 20 patients (2.2%/patient-year) and cancer in 3 patients (0.3%/patient-year). Baseline dysplasia (hazard ratio [HR], 1.71; 95% CI, 1.03-2.84) and long-segment BE (HR, 1.59; 95% CI, 1.01-2.51) increased risk of BE recurrence whereas treatment at high-volume RFA facilities reduced risk of BE recurrence (for quartile 4 vs quartile 1: HR, 0.19; 95% CI, 0.05-0.68). CONCLUSIONS In a nationwide VA system study of outcomes of RFA for BE, we associated baseline dysplasia, long-segment BE, and treatment at low-volume RFA centers with recurrence of BE after CEIM. The findings call for performing these procedures in high-volume centers.

Abstract
The management of Barrett's esophagus and early esophageal adenocarcinoma has shifted away from esophagectomy and toward endoscopic techniques, including endoscopic resection and ablative therapies. The most commonly used ablative therapies are radiofrequency ablation and cryotherapy. Radiofrequency ablation has risen to the top of the management algorithm due to its favorable safety profile and established track record of efficacy in patients with dysplastic Barrett's. Cryotherapy offers early promise as an alternatively safe and effective ablative modality. We review radiofrequency ablation and cryotherapy techniques, and updated data regarding their efficacy and safety as well as their roles in the management of Barrett's esophagus.

Abstract
GOALS To report the rate of eradication and recurrence of both neoplasia and intestinal mucosa and the rate of adverse events for complete endoscopic resection (CER) of Barrett esophagus (BE). BACKGROUND There is limited composite data on the clinical efficacy of CER of BE with high-grade dysplasia or neoplasia. STUDY We performed a systematic review and meta-analysis of cohort studies that reported the clinical outcome of patients with BE who underwent CER and had at least 15-month follow-up after the time of elimination of BE. Main outcome of interests were pooled estimated rates of complete eradication of intestinal metaplasia and neoplasia, recurrence of intestinal metaplasia and neoplasia, and incidence of esophageal stricture, bleeding, and perforation. RESULTS We identified 8 studies reporting on 676 patients (high-grade dysplasia 54%) that met our criteria. Pooled estimated rates of complete eradication of intestinal metaplasia and complete eradication of intestinal neoplasia were 85.0% [95% confidence interval (CI), 79.4%-89.2%] and 96.6% (95% CI, 94.0%-98.1%), respectively, and rates of recurrence of intestinal metaplasia and recurrence of intestinal neoplasia were 15.7% (95% CI, 8.0%-28.4%) and 5.8% (95% CI, 3.9%-8.6%), respectively. Estimated incidences of adverse events were stricture 37.4 (95% CI, 24.4%-52.6%), bleeding 7.9% (95% CI, 4.4%-13.8%) and perforation 2.3% (95% CI, 1.3%-4.1%). CONCLUSIONS CER achieves an 85% complete eradication rate of BE with recurrent rate of neoplasia of 6%. Estimated rate of postprocedural stricture was 37.4%. On the basis of this high rate of adverse events and significant heterogeneity in the studies included, the present meta-analysis cannot endorse CER as sole therapy for BE.

Abstract
Oesophageal cancer is a clinically challenging disease that requires a multidisciplinary approach. Extensive treatment might be associated with a considerable decline in health-related quality of life and yet still a poor prognosis. In recent decades, prognosis has gradually improved in many countries. Endoscopic procedures have increasingly been used in the treatment of premalignant and early oesophageal tumours. Neoadjuvant therapy with chemotherapy or chemoradiotherapy has supplemented surgery as standard treatment of locally advanced oesophageal cancer. Surgery has become more standardised and centralised. Several therapeutic alternatives are available for palliative treatment. This Seminar aims to provide insights into the current clinical management, ongoing controversies, and future needs in oesophageal cancer.

Abstract
In the last decade, radiofrequency ablation in combination with endoscopic mucosal resection has simplified and improved the treatment of Barrett's esophagus. These treatments not only reduced the progression of dysplastic Barrett's esophagus to esophageal adenocarcinoma but also decreased treatment-related complications. More recent data from larger series with extended follow-up periods are emerging to refine expectations in patients treated with radiofrequency ablation. Although most patients achieve eradication of neoplasia and intestinal metaplasia, in the long-term a substantial portion of patients develop recurrent disease. This article provides an updated review of radiofrequency ablation efficacy, complications, and durability.

Abstract
Endoscopic therapies have become the standard of care for most cases of Barrett's esophagus with high-grade dysplasia or intramucosal adenocarcinoma. Despite a rapid and dramatic evolution in treatment paradigms, esophagectomy continues to occupy a place in the therapeutic armamentarium for superficial esophageal neoplasia. The managing physician must remain cognizant of the limitations of endoscopic approaches and consider surgical resection when they are exceeded. Esophagectomy, performed at experienced centers for appropriately selected patients with early-stage disease can be undertaken with the expectation of cure as well as low mortality, acceptable morbidity, and good long-term quality of life.

Abstract
Endoscopic eradication therapy (EET), the standard of care for treatment of Barrett's esophagus with dysplasia and early neoplasia, consists of a combination of endoscopic resection and ablative modalities. Resection techniques primarily include endoscopic mucosal resection or endoscopic submucosal dissection. Resection of nodular disease is generally followed by one of multiple ablative therapies among which radiofrequency ablation has the best evidence supporting safety and efficacy. These advanced endoscopic procedures require both experience and expertise in the cognitive and procedural aspects of EET. However, very few formal programs exist that teach endoscopists the necessary skills to perform EET in a safe, standardized, and efficacious manner. Case volume at both the endoscopist and center level has been shown to impact clinical outcomes based on limited data. As a result, some recent guidelines endorse case volume as a measure of competency. Quality indicators, which can be used as benchmarks for training and as part of pay for quality initiatives, have recently been derived for EET. However, quality metrics in EET have not been widely accepted, nor are they broadly used currently. While the efficacy of EET for BE is established, there is a need for application of quality metrics to both assure adequate training in these procedures, as well as to assess treatment outcomes. A standardized EET training curriculum during endoscopic training, with competency assessment of both new clinicians and endoscopists in practice has potential to improve care in EET.

Abstract
The purpose of this clinical practice update expert review is to define the key principles in the diagnosis and management of low-grade dysplasia (LGD) in Barrett's esophagus patients. The best practices outlined in this review are based on relevant publications, including systematic reviews and expert opinion (when applicable). Practice Advice 1: The extent of Barrett's esophagus should be defined using a standardized grading system documenting the circumferential and maximal extent of the columnar lined esophagus (Prague classification) with a clear description of landmarks and visible lesions (nodularity, ulceration) when present. Practice Advice 2: Given the significant interobserver variability among pathologists, the diagnosis of Barrett's esophagus with LGD should be confirmed by an expert gastrointestinal pathologist (defined as a pathologist with a special interest in Barrett's esophagus-related neoplasia who is recognized as an expert in this field by his/her peers). Practice Advice 3: Expert pathologists should report audits of their diagnosed cases of LGD, such as the frequency of LGD diagnosed among surveillance patients and/or the difference in incidence of neoplastic progression among patients diagnosed with LGD vs nondysplastic Barrett's esophagus. Practice Advice 4: Patients in whom the diagnosis of LGD is downgraded to nondysplastic Barrett's esophagus should be managed as nondysplastic Barrett's esophagus. Practice Advice 5: In Barrett's esophagus patients with confirmed LGD (based on expert gastrointestinal pathology review), repeat upper endoscopy using high-definition/high-resolution white-light endoscopy should be performed under maximal acid suppression (twice daily dosing of proton pump inhibitor therapy) in 8-12 weeks. Practice Advice 6: Under ideal circumstances, surveillance biopsies should not be performed in the presence of active inflammation (erosive esophagitis, Los Angeles grade C and D). Pathologists should be informed if biopsies are obtained in the setting of erosive esophagitis and if pathology findings suggest LGD, or if no biopsies are obtained, surveillance biopsies should be repeated after the anti-reflux regimen has been further intensified. Practice Advice 7: Surveillance biopsies should be performed in a four-quadrant fashion every 1-2 cm with target biopsies obtained from visible lesions taken first. Practice Advice 8: Patients with a confirmed histologic diagnosis of LGD should be referred to an endoscopist with expertise in managing Barrett's esophagus-related neoplasia practicing at centers equipped with high-definition endoscopy and capable of performing endoscopic resection and ablation. Practice Advice 9: Endoscopic resection should be performed in Barrett's esophagus patients with LGD with endoscopically visible abnormalities (no matter how subtle) in order to accurately assess the grade of dysplasia. Practice Advice 10: In patients with confirmed Barrett's esophagus with LGD by expert GI pathology review that persists on a second endoscopy, despite intensification of acid-suppressive therapy, risks and benefits of management options of endoscopic eradication therapy (specifically adverse events associated with endoscopic resection and ablation), and ongoing surveillance should be discussed and documented. Practice Advice 11: Endoscopic eradication therapy should be considered in patients with confirmed and persistent LGD with the goal of achieving complete eradication of intestinal metaplasia. Practice Advice 12: Patients with LGD undergoing surveillance rather than endoscopic eradication therapy should undergo surveillance every 6 months times 2, then annually unless there is reversion to nondysplastic Barrett's esophagus. Biopsies should be obtained in 4-quadrants every 1-2 cm and of any visible lesions. Practice Advice 13: In patients with Barrett's esophagus-related LGD undergoing ablative therapy, radiofrequency ablation should be used. Practice Advice 14: Patients completing endoscopic eradication therapy should be enrolled in an endoscopic surveillance program. Patients who have achieved complete eradication of intestinal metaplasia should undergo surveillance every year for 2 years and then every 3 years thereafter to detect recurrent intestinal metaplasia and dysplasia. Patients who have not achieved complete eradication of intestinal metaplasia should undergo surveillance every 6 months for 1 year after the last endoscopy, then annually for 2 years, then every 3 years thereafter. Practice Advice 15: Following endoscopic eradication therapy, the biopsy protocol of obtaining biopsies in 4 quadrants every 2 cm throughout the length of the original Barrett's esophagus segment and any visible columnar mucosa is suggested. Practice Advice 16: Endoscopists performing endoscopic eradication therapy should report audits of their rates of complete eradication of dysplasia and intestinal metaplasia and adverse events in clinical practice.

Abstract
INTRODUCTION The diversity, technical skills required, and risk inherent to advanced endoscopy techniques all contribute to complex training curricula and steep learning curves. Since trainees develop endoscopy skills at different rates, there has been a shift towards competency-based training and certification. Validated endoscopy performance measures for trainees are, therefore, necessary. The aim of this systematic review was to describe and critically assess the existing evidence regarding measures of performance for trainees in advanced endoscopy. METHODS A systematic review of the literature from January 1980 to January 2016 was carried out using the MEDLINE, EMBASE, CENTRAL, and ISI Web of knowledge databases. MeSH terms related to 'advanced endoscopy' and 'performance' were applied to a highly sensitive search strategy. The main outcomes were face, content, and construct validity, as well as reliability. RESULTS The literature search yielded 1,662 studies and 77 met the inclusion criteria after abstract and full-text review (endoscopic retrograde cholangiopancreatography (ERCP)=23, endoscopic ultrasound (EUS)=30, colonoscopic polypectomy (CP)=11, balloon-assisted enteroscopy (BAE)=7, luminal stenting=3, radiofrequency ablation (RFA)=2, and endoscopic muscosal resection (EMR)=1). Good validity and reliability were found for measurement tools of overall performance in ERCP, EUS and CP, with applications for both patient-based and simulator training models. A number of specific technical skills were also shown to be valid measures of performance. These include: selective biliary cannulation, sphincterotomy, biliary stent placement, stone extraction and procedure time for ERCP; pancreatic solid mass T-staging, EUS-guided fine needle aspiration (EUS-FNA) procedure time, number of EUS-FNA passes and puncture precision for EUS; procedure time and en bloc resection rate for CP; retrograde fluoroscopy time for BAE; and mean number of endoscopy sessions required to achieve complete eradication of intestinal metaplasia (CIEM) for RFA. The evidence for EMR and luminal stenting is of insufficient quality to make recommendations. CONCLUSIONS We have identified multiple valid and readily available performance measures for advanced endoscopy trainees for ERCP, EUS, CP, BAE and RFA procedures. These tools should be considered in advanced endoscopy training programs wishing to move away from apprenticeship-based training and towards competency-based learning with the help of patient-based and simulator tools.
