Abstract
Evaluating clinical care through quality-related metrics is increasingly common. There are now numerous quality statements and indicators related to the medical management of benign and pre-malignant esophageal diseases. Expert consensus leveraging evidence-based recommendations from published society guidelines has been the most frequently used basis for developing esophageal quality statements. While surgical care of patients with esophageal malignancies, including squamous cell carcinoma, has also been developed, those related to benign esophageal disease now include domains of diagnosis, treatment, and monitoring for gastroesophageal reflux disease, eosinophilic esophagitis (EoE), achalasia, and Barrett's esophagus (BE). Several recent studies evaluating adherence to quality metrics affirm substantial variation in practice patterns with opportunities for improvement in care across esophageal diseases. In particular, patient education regarding treatment options in achalasia, frequency of esophageal biopsies among patients with dysphagia to evaluate for EoE, and endoscopic evaluation within a BE segment are areas identified to have need for improvement. As the management of esophageal diseases becomes more complex and interdisciplinary, adherence to quality metrics may be a source of standardization and improvement in delivery and ultimately patient outcomes. Indeed, the development of national quality databases has resulted in a significant growth in the use of these metrics for quality improvement activities and may form the basis for future inclusion in quality reporting and payment programs.

Abstract
There is growing interest in establishing quality indicators (QIs) for endoscopic screening and surveillance in Barrett's esophagus (BE). QIs are objective, measurable, and evidence-based metrics that are applicable in a health-care setting to monitor a process and identify key performance indicators (KPIs) to achieve defined goals. In the Barrett's endoscopy setting, QIs can offer a standardized approach to monitor and maintain high-quality endoscopy for BE screening and surveillance that will allow measuring performance of an endoscopist as an individual, a group, or a facility. Since BE is an endoscopically identifiable premalignant condition with histological corroboration, adherence to QIs is paramount for the early and accurate detection of dysplasia and neoplasia. It is the holy grail for BE screening and surveillance. Although several suggested QIs for Barrett's endoscopy exist, issues remain in determining the most appropriate ones. These issues include inconsistent use of terminology, unclear definitions, and a scarcity of studies linking these QIs with relevant patient outcomes, making it difficult for clinicians to understand the concept and clinical importance. Hence, there is an urgent need to determine what should constitute appropriate QIs for Barrett's endoscopy, clearly define items used in the QIs, and identify ways to measure these KPIs. Ultimately, well-defined and validated QIs will contribute to clinically effective, safe, timely, and patient-focused care. In this review, we summarize recent literature and discuss four proposed QIs: (i) neoplasia detection rate; (ii) postendoscopy Barrett's neoplasia; (iii) Barrett's inspection time; and (iv) adherence to the Seattle biopsy protocol.

Abstract
Recent guidelines recommend screening for patients with chronic gastroesophageal reflux disease who have three or more additional risk factors for Barrett's esophagus (BE). Failure to screen high-risk individuals represents a missed opportunity in esophageal adenocarcinoma prevention and early detection. We aimed to determine the frequency of upper endoscopy and prevalence of BE and esophageal cancer in a cohort of United States veterans who possessed four or more risk factors for BE. All patients at VA New York Harbor Healthcare System with at least four risk factors for BE between 2012 and 2017 were identified. Procedure records were reviewed for upper endoscopies performed between January 2012 and December 2019. Multivariable logistic regression was used to determine risk factors associated with undergoing endoscopy and factors associated with BE and esophageal cancer. 4505 patients with at least four risk factors for BE were included. 828 patients (18.4%) underwent upper endoscopy, of which 42 (5.1%) were diagnosed with BE and 11 (1.3%) with esophageal cancer (10 adenocarcinoma; 1 squamous cell carcinoma). Among individuals who underwent upper endoscopy, risk factors associated with undergoing endoscopy included obesity (OR, 1.79; 95% CI, 1.41-2.30; P < 0.001) and chronic reflux (OR, 3.86; 95% CI, 3.04-4.90; P < 0.001). There were no individual risk factors associated with BE or BE/esophageal cancer. In this retrospective analysis of patients with 4 or more risk factors for BE, fewer than one-fifth of patients underwent upper endoscopy, supporting the need for efforts aimed at improving BE screening rates.

Abstract
Barrett esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), a cancer that continues to have a poor 5-year survival rate of 20%. Current BE screening strategies aim to detect BE and EAC at early, curable stages, but the majority of patients with EAC are diagnosed outside of BE screening and surveillance programs. Guidelines around the world suggest screening for BE in patients with gastroesophageal reflux disease (GERD) and additional demographic and clinical risk factors using high-definition white-light endoscopy (HDWLE). However, current strategies relying on HDWLE are problematic with high direct and indirect costs, procedural risks, and limitations in patient selection owing to the low sensitivity of GERD as a risk factor for detection of BE. In an effort to address these shortcomings, a variety of other screening strategies are under investigation, including risk prediction algorithms, noninvasive cell collection devices, and other new technologies to make screening more efficient and cost-effective. At this time, only cell collection devices have been integrated into professional guidelines, and clinical implementation of alternatives to endoscopy has lagged. In the future, screening may be personalized using a combination of different screening modalities. This article discusses the current state of BE screening and new approaches that may alter the future of screening.

Abstract
Background and Objective This narrative review discusses Barrett's esophagus management in the context of perceived deficiencies or controversies. Barrett's adenocarcinoma incidence has not clearly been impacted by Barrett's screening and surveillance. Methods The following report was derived from articles using PubMed and Google searches. The search was concentrated on Barrett's esophagus screening and management guidelines. Key Content and Findings Comprehensive literature searches that highlight potential deficiencies or controversies regarding the current approach to Barrett's esophagus were employed. Esophageal adenocarcinoma incidence is rapidly increasing and this malignancy usually presents in an advanced and unresectable state. This is despite the significant expenditure of resources and time in endoscopic screening for and surveillance of Barrett's esophagus. Thus, more widespread screening for Barrett's esophagus may be considered. In addition, there are apparent inefficiencies and precision lack in the performance of endoscopic surveillance. This relates mainly to the lack of endoscopic cues for dysplasia. On the other hand, relatively low-risk subjects have frequent screening or surveillance procedures increasing cost. Lastly, endoscopic ablation for Barrett's with dysplasia has moderately good efficacy, especially for eradication of dysplasia, but mandates intensive post-therapy endoscopic surveillance. There is some concern for subsurface development of advanced Barrett's lesions. Fortunately, there is intense research in improving Barrett's esophagus diagnosis and treatment. Our narrative review will delineate deficiencies and potential measures to remedy them. Conclusions In conclusion, screening for Barrett's esophagus and surveillance in Barrett's subjects have minimal established benefits, but proposed changes in screening practices and innovations in Barrett's esophagus endoscopic surveillance and dysplasia therapy have great promise.

Abstract
BACKGROUND & AIMS Identifying dysplasia of Barrett's esophagus (BE) in the electronic medical record (EMR) requires manual abstraction of unstructured data. Natural language processing (NLP) creates structure to unstructured free text. We aimed to develop and validate an NLP algorithm to identify dysplasia in BE patients on histopathology reports with varying report formats in a large integrated EMR system. METHODS We randomly selected 600 pathology reports for NLP development and 400 reports for validation from patients with suspected BE in the national Veterans Affairs databases. BE and dysplasia were verified by manual review of the pathology reports. We used NLP software (Clinical Language Annotation, Modeling, and Processing Toolkit; Melax Tech, Houston, TX) to develop an algorithm to identify dysplasia using findings. The algorithm performance characteristics were calculated as recall, precision, accuracy, and F-measure. RESULTS In the development set of 600 patients, 457 patients had confirmed BE (60 with dysplasia). The NLP identified dysplasia with 98.0% accuracy, 91.7% recall, and 93.2% precision, with an F-measure of 92.4%. All 7 patients with confirmed high-grade dysplasia were classified by the algorithm as having dysplasia. Among the 400 patients in the validation cohort, 230 had confirmed BE (39 with dysplasia). Compared with manual review, the NLP algorithm identified dysplasia with 98.7% accuracy, 92.3% recall, and 100.0% precision, with an F-measure of 96.0%. CONCLUSIONS NLP yielded a high degree of sensitivity and accuracy for identifying dysplasia from diverse types of pathology reports for patients with BE. The application of this algorithm would facilitate research and clinical care in an EMR system with text reports in large data repositories.

Abstract
INTRODUCTION Despite societal recommendations supporting Barrett's esophagus (BE) screening, it is unknown what proportion of eligible patients is screened in primary care. We assessed the proportion of BE screening- eligible patients evaluated in the primary care setting receiving upper esophagogastroduodenoscopy (EGD) and identified factors associated with undergoing EGD. METHODS This was a retrospective study of BE screening-eligible patients, as defined by the American College of Gastroenterology's BE guidelines, in a multipractice healthcare network consisting of 64 internal medicine practices and 94 family medicine (FM) practices. The proportion undergoing EGD, prevalence of BE and esophageal adenocarcinoma (EAC) in this group, and patient and provider factors associated with undergoing EGD were assessed. Multivariable logistic regression was performed to identify independent predictors of undergoing EGD. RESULTS Of 1,127 screening-eligible patients, the mean age was 65.2 ± 8.6 years; 45% were obese; and 61% were smokers. Seventy-three percent were seeing FM; 94% were on proton pump inhibitors; and 44% took ≥1 gastroesophageal reflux disease (GERD) medication. Only 39% of patients (n = 436) had undergone EGD. The overall prevalence of BE or EAC was 9.9%. Of 39 (9%) referred for BE screening as the primary indication, BE/EAC prevalence was 35.1%. Factors associated with increased odds of having EGD were symptomatic GERD despite treatment (odds ratio [OR] 12.1, 95% confidence interval [CI] 9.1-16.3), being on ≥1 GERD medication (OR 1.4, 95% CI 1.0-1.9), and being an FM patient (OR 1.5, 95% CI 1.1-2.1). DISCUSSION In this large, primary care population, only 39% of screening-eligible patients underwent EGD. Most of the examinations were triggered by refractory symptoms rather than screening referrals, highlighting a need for improved dissemination and implementation of BE screening.

Abstract
BACKGROUND Endoscopic surveillance is recommended for patients with Barrett's oesophagus because, although the progression risk is low, endoscopic intervention is highly effective for high-grade dysplasia and cancer. However, repeated endoscopy has associated harms and access has been limited during the COVID-19 pandemic. We aimed to evaluate the role of a non-endoscopic device (Cytosponge) coupled with laboratory biomarkers and clinical factors to prioritise endoscopy for Barrett's oesophagus. METHODS We first conducted a retrospective, multicentre, cross-sectional study in patients older than 18 years who were having endoscopic surveillance for Barrett's oesophagus (with intestinal metaplasia confirmed by TFF3 and a minimum Barrett's segment length of 1 cm [circumferential or tongues by the Prague C and M criteria]). All patients had received the Cytosponge and confirmatory endoscopy during the BEST2 (ISRCTN12730505) and BEST3 (ISRCTN68382401) clinical trials, from July 7, 2011, to April 1, 2019 (UK Clinical Research Network Study Portfolio 9461). Participants were divided into training (n=557) and validation (n=334) cohorts to identify optimal risk groups. The biomarkers evaluated were overexpression of p53, cellular atypia, and 17 clinical demographic variables. Endoscopic biopsy diagnosis of high-grade dysplasia or cancer was the primary endpoint. Clinical feasibility of a decision tree for Cytosponge triage was evaluated in a real-world prospective cohort from Aug 27, 2020 (DELTA; ISRCTN91655550; n=223), in response to COVID-19 and the need to provide an alternative to endoscopic surveillance. FINDINGS The prevalence of high-grade dysplasia or cancer determined by the current gold standard of endoscopic biopsy was 17% (92 of 557 patients) in the training cohort and 10% (35 of 344) in the validation cohort. From the new biomarker analysis, three risk groups were identified: high risk, defined as atypia or p53 overexpression or both on Cytosponge; moderate risk, defined by the presence of a clinical risk factor (age, sex, and segment length); and low risk, defined as Cytosponge-negative and no clinical risk factors. The risk of high-grade dysplasia or intramucosal cancer in the high-risk group was 52% (68 of 132 patients) in the training cohort and 41% (31 of 75) in the validation cohort, compared with 2% (five of 210) and 1% (two of 185) in the low-risk group, respectively. In the real-world setting, Cytosponge results prospectively identified 39 (17%) of 223 patients as high risk (atypia or p53 overexpression, or both) requiring endoscopy, among whom the positive predictive value was 31% (12 of 39 patients) for high-grade dysplasia or intramucosal cancer and 44% (17 of 39) for any grade of dysplasia. INTERPRETATION Cytosponge atypia, p53 overexpression, and clinical risk factors (age, sex, and segment length) could be used to prioritise patients for endoscopy. Further investigation could validate their use in clinical practice and lead to a substantial reduction in endoscopy procedures compared with current surveillance pathways.

Abstract
BACKGROUND AND AIMS Less than 10% of patients diagnosed with esophageal adenocarcinoma have a pre-existing Barrett's esophagus (BE) diagnosis, possibly because of suboptimal performance of guidelines. We examined the prevalence of BE in a previously unscreened primary care population and the potential yield of practice BE screening guidelines. METHODS This was a retrospective analysis of a prospective cross-sectional study of consecutively recruited unreferred patients from primary care clinics who underwent study upper endoscopy. We examined the performance of BE screening guidelines of the European Society of Gastrointestinal Endoscopy (ESGE), British Society of Gastroenterology (BSG), American Society for Gastrointestinal Endoscopy (ASGE), American College of Gastroenterology (ACG), American Gastroenterological Association (AGA), and our own modification of guidelines. RESULTS We identified 44 BE cases and 469 control subjects (prevalence, 8.6%). Among 371 patients without GERD symptoms, 25 (6.7%) had BE. The AGA guidelines requiring ≥2 BE risk factors had sensitivity of 100% and specificity of only .2%, whereas ACG, ASGE, ESGE, and BSG guidelines (all requiring GERD first) had low sensitivities (38.6%-43.2%), specificities ranging from 67.4% to 76.5%, and area under the receiver operating curve (AUROC) of .50 to .60. Our 2-pronged approach depending on presence or absence of GERD symptoms but with other risk factors achieved sensitivity of 81.8%, specificity of 51.2%, and AUROC of .66. CONCLUSIONS Over half of BE cases were without frequent GERD symptoms, but virtually all had at least 1 known BE risk factor. Practice guidelines requiring GERD symptoms have low sensitivity, whereas those not requiring GERD have low specificity. We have proposed a screening guideline with better use of known risk factors.

Abstract
PURPOSE OF REVIEW Barrett's esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), a cancer associated with increasing incidence and poor survival. Early identification and effective treatment of BE-related neoplasia prior to the development of invasive adenocarcinoma are essential to limiting the morbidity and mortality associated with this cancer. In this review, we summarized the recent evidence guiding endoscopic eradication therapies (EET) for neoplastic BE. RECENT FINDINGS New sampling technologies and the application of artificial intelligence (AI) systems have potential to revolutionize early neoplasia detection in BE. EET for BE are safe and effective in achieving complete eradication of intestinal metaplasia (CE-IM) and reducing the progression to EAC, a practice endorsed by all GI society guidelines. EET should be considered in patients with high-grade dysplasia (HGD), intramucosal carcinoma (IMC), and select cases with low-grade dysplasia (LGD). The increasing use of endoscopic submucosal dissection (ESD) in the West may allow EET of select cases with submucosal EAC. Post-EET surveillance strategies will continue to evolve as knowledge of specific risk factors and long-term neoplasia recurrence rates improve. In the last decade, major advancements in EET for neoplastic BE have been achieved. These now represent the standard of care in the management of BE-related dysplasia and intramucosal cancer.

Abstract
BACKGROUND The proportions of patients with oesophageal adenocarcinoma (OAC) diagnosed by Barrett's oesophagus surveillance or with pre-existing Barrett's oesophagus are unclear. AIM To estimate the prevalence of prior and concurrent Barrett's oesophagus diagnosis among patients with OAC or oesophagogastric junction adenocarcinomas (OGJAC). METHODS We searched PubMed and Embase to identify studies published 1966-1/8/2020 that examined the prevalence of prior (≥6 months) or concurrent Barrett's diagnosis (at cancer diagnosis) among OAC and OGJAC patients. Random effects models estimated overall and stratified pooled prevalence rates. RESULTS A total of 69 studies, including 33 002 OAC patients (53 studies) and 2712 patients with OGJAC (28 studies) were included. The pooled prevalence of prior Barrett's oesophagus diagnosis in OAC was 11.8% (95% confidence interval [CI] 8.4%-15.6%). The prevalence of prior Barrett's oesophagus diagnosis was higher in single-centre resection studies (16.0%, 95% CI 8.7%-24.9%) than population-based cancer registry studies (8.4%, 95% CI 5.5%-11.9%). The prevalence of concurrent Barrett's oesophagus in OAC was 56.6% (95% CI 48.5%-64.6%). Studies with 100% early stage OAC had higher prevalence of concurrent Barrett's oesophagus (91.3%, 95% CI 82.4%-97.6%) than studies with <50% early OAC (39.7%, 95% CI 33.7%-45.9%). In OGJAC, the prevalence of prior and concurrent Barrett's oesophagus was 23.2% (95% CI 7.5%-44.0%) and 26.3% (95% CI 17.8%-35.7%), respectively. CONCLUSIONS Most patients with OAC have Barrett's oesophagus. Our meta-analysis found ~12% of OAC patients had prior Barrett's diagnosis, but concurrent Barrett's oesophagus was found in ~57% at the time of OAC diagnosis. This represents a considerable missed opportunity for Barrett's oesophagus screening.

Abstract
PURPOSE OF REVIEW Barrett's oesophagus is the only identifiable precursor lesion to oesophageal adenocarcinoma. The stepwise progression of Barrett's oesophagus to dysplasia and invasive carcinoma provides the opportunity to intervene and reduce the morbidity and mortality associated with this lethal cancer. Several studies have demonstrated the efficacy and safety of endoscopic eradication therapy (EET) for the management of Barrett's oesophagus related neoplasia. The primary goal of EET is to achieve complete eradication of intestinal metaplasia (CE-IM) followed by enrolment of patients in surveillance protocols to detect recurrence of Barrett's oesophagus and Barrett's oesophagus related neoplasia. RECENT FINDINGS EET depends on early and accurate detection and diagnosis of Barrett's oesophagus related neoplasia. All visible lesions should be resected followed by ablation of the remaining Barrett's epithelium. After treatment, patients should be enrolled in endoscopic surveillance programmes. For nondysplastic Barrett's oesophagus, surveillance alone is recommended. For low-grade dysplasia, both surveillance and ablation are reasonable options and should be decided on an individual basis according to patient risk factors and preferences. EET is preferred for high-grade dysplasia and intramucosal carcinoma. For T1b oesophageal adenocarcinoma, esophagectomy remains the standard of care, but endoscopic therapy can be considered in select cases. SUMMARY EET is now standard of care and endorsed by societal guidelines for the treatment of Barrett's oesophagus related neoplasia. Future studies should focus on risk stratification models using a combination of clinical data and biomarkers to identify ideal candidates for EET, and to predict recurrence. Optimal therapy for T1b cancer and surveillance strategy after CE-IM are topics that require further study.

Abstract
Barrett esophagus (BE) is the only known premalignant precursor to esophageal adenocarcinoma (EAC), a deadly malignancy that carries a dismal prognosis. Guidelines currently recommend screening for BE only in high-risk populations, such as patients with chronic gastroesophageal reflux disease (GERD) and 1 or more additional risk factors. A GERD-centered approach to BE screening likely leads to a large number of missed EAC cases, as the true population prevalence of BE is thought to be much higher than current estimates. Mass screening for BE has been proposed but is fraught with challenges. Esophagogastroduodenoscopy screening is the current gold standard for BE detection, but it is expensive and cumbersome and carries a small potential for unwanted harms. Transnasal endoscopy is simple, cost-effective, and well tolerated, but it has not found widespread acceptance among physicians and patients. Esophageal capsule endoscopy, despite being well tolerated and accepted, has not been shown to be cost-effective. Newer minimally invasive, nonendoscopic techniques for BE screening have shown promise in prospective clinical trials. Pragmatic head-to-head trials comparing these techniques will help determine the path forward and could herald a new future for population-based BE screening.

Abstract
Esophageal adenocarcinoma is inflammation-associated cancer with a recognizable preneoplastic stage, Barrett's. Barrett's describes the metaplastic transformation of esophageal squamous mucosa into columnar epithelium that typically results secondary to mucosal damage caused by acidic gastroduodenal reflux. Continued acid reflux may then result in mucosal inflammation which results in progressive inflammation-induced genetic instability that may eventuate in esophageal adenocarcinoma. Barrett's is the only recognized precursor lesion to esophageal carcinoma. Barrett's mucosa is unique among preneoplastic lesions; ablation therapy results in restitution of a squamous epithelium reducing or eliminating accumulated genetic instabilities and resetting the biological clock progressing toward invasive cancer. However, recurrence of Barrett's after ablation is common. We propose that both Barrett's and recurrence of Barrett's after ablation can be prevented and discuss how current approaches to therapy for gastroesophageal reflux disease, for Barrett's screening, chemoprevention, and ablation therapy all might be reconsidered. We propose (1) improved approaches to Barrett's prevention, (2) universal Barrett's screening by linking Barrett's screening to colon cancer screening, (3) ablation of all Barrett's mucosa along with (4) acid-suppressive-antireflux therapy tailored to prevent development of Barrett's or the recurrence of Barrett's after ablation therapy. We propose that ultimately, treatment decisions for gastroesophageal reflux disease and prevention of Barrett's and esophageal carcinoma should be based on assessing and maintaining esophageal mucosal integrity. This will require development and verification of specific measurements that reliably correlate with prevention of Barrett's. We outline the new research and technical advances needed to cost-effectively achieve these goals.

Syst Rev 2020; 9:20. [PMID: 31996261 PMCID: PMC6990541 DOI: 10.1186/s13643-020-1275-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Accepted: 01/07/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Two reviews and an overview were produced for the Canadian Task Force on Preventive Health Care guideline on screening for esophageal adenocarcinoma in patients with chronic gastroesophageal reflux disease (GERD) without alarm symptoms. The goal was to systematically review three key questions (KQs): (1) The effectiveness of screening for these conditions; (2) How adults with chronic GERD weigh the benefits and harms of screening, and what factors contribute to their preferences and decision to undergo screening; and (3) Treatment options for Barrett's esophagus (BE), dysplasia or stage 1 EAC (overview of reviews). METHODS Bibliographic databases (e.g. Ovid MEDLINE®) were searched for each review in October 2018. We also searched for unpublished literature (e.g. relevant websites). The liberal accelerated approach was used for title and abstract screening. Two reviewers independently screened full-text articles. Data extraction and risk of bias assessments were completed by one reviewer and verified by another reviewer (KQ1 and 2). Quality assessments were completed by two reviewers independently in duplicate (KQ3). Disagreements were resolved through discussion. We used various risk of bias tools suitable for study design. The GRADE framework was used for rating the certainty of the evidence. RESULTS Ten studies evaluated the effectiveness of screening. One retrospective study reported no difference in long-term survival (approximately 6 to 12 years) between those who had a prior esophagogastroduodenoscopy and those who had not (adjusted HR 0.93, 95% confidence interval (CI) 0.58-1.50). Though there may be higher odds of a stage 1 diagnosis than a more advanced diagnosis (stage 2-4) if an EGD had been performed in the previous 5 years (OR 2.27, 95% CI 1.00-7.67). Seven studies compared different screening modalities, and showed little difference between modalities. Three studies reported on patients' unwillingness to be screened (e.g. due to anxiety, fear of gagging). Eleven systematic reviews evaluated treatment modalities, providing some evidence of early treatment effect for some outcomes. CONCLUSIONS Little evidence exists on the effectiveness of screening and values and preferences to screening. Many treatment modalities have been evaluated, but studies are small. Overall, there is uncertainty in understanding the effectiveness of screening and early treatments.

Abstract
BACKGROUND Though over one-third of veterans suffer from obesity and its associated comorbidities, bariatric surgery (deleted: is seldom offered) is less commonly offered than in other populations. METHODS We reviewed surgical outcomes using CPRS/Vista data of ("deleted 308) 315 Roux-en-Y gastric bypass (RYGB) cases performed at a major VA Medical Center (1995-2017). RESULTS Patients were 69% male, with an average age 52 (65% over 50), and were followed for an average of 8 years; 158 (51%) underwent laparoscopic surgery, and the remaining open. Outcomes were: 30-day mortality- Open: 1.3%, Lap: 0%; anatomic leak-open: 0.3%, Lap: 0%. A total of 32 (10%) Clavien-Dindo ≥3 complications occurred. At 5 and 15 years, average BMI decreased from 47 preoperatively to 33.3 and 31 respectively, while excess body weight loss was 68%, and 80%, respectively. Co-morbidity resolution rates were between 70 and 80% diabetes, sleep apnea, hyperlipidemia, GERD, (delete - hypertension), and NASH. CONCLUSIONS RYGB offers sustained, long-term weight loss with significant resolution of major comorbidities in older veterans, with acceptably low morbidity and mortality.
