Abstract
OBJECTIVES The current surveillance strategy in Barrett's esophagus (BE) uses only histological findings of the last endoscopy to assess neoplastic progression risk. As predictor values vary across endoscopies, single measurements may not be an accurate reflection. Our aim was to explore the value of using longitudinal evolutions (i.e. successive measurements) of histological findings (low-grade dysplasia (LGD)) and immunohistochemical biomarkers (p53 and SOX2) by investigating the association with Barrett's progression. METHODS In this proof-of-principle study of a longitudinal dynamic risk estimation model with a multicenter cohort design, 631 BE patients from 15 Dutch hospitals who were under surveillance were included. Longitudinal dynamic values of LGD, p53, and SOX2 were included in a multivariate joint model to estimate the risk of high-grade dysplasia (HGD)/esophageal adenocarcinoma (EAC). RESULTS Longitudinal evolutions of aberrant expression of p53 (HR 1.26, p<0.01) and SOX2 (HR 1.43, p<0.01) were associated with an increased HGD/EAC risk. We also found weak evidence of an association with the longitudinal evolution of the presence of LGD (HR 1.02, p = 0.12). The performance of the model was good (AUC 0.80-0.88). Using this model, for each future BE patient the probability of aberrant expression of biomarkers based on multiple longitudinal observations can be estimated. This probability is translated in progression risk, expressed as HR. CONCLUSIONS This study provides solid ground to further explore a paradigm shift from currently recommended fixed intervals towards personalized surveillance, in which tailored risk estimations and corresponding surveillance intervals can be updated at every FU endoscopy for individual BE patients.

Abstract
Barrett esophagus (BE), defined as intestinal metaplasia of the distal esophageal mucosa, typically results from chronic gastroesophageal reflux disease and is the only known precursor of esophageal adenocarcinoma. The standard of care for the management of early esophageal neoplasia in the setting of BE has changed drastically over the past 15 years. Further investigation into diagnostic and therapeutic adjuncts will continue to improve our ability to control or cure BE before its advancement to a life-threatening malignancy.

Abstract
BACKGROUND Fundoplication and medical management are current mainstays for management of Barrett's esophagus (BE), however our understanding of differences in outcomes between these two treatments is limited. The aim of this study was to perform a systematic review and meta-analysis to evaluate the efficacy of these interventions on BE disease regression and progression. METHODS AND PROCEDURES A comprehensive search in MEDLINE, EMBASE, Scopus, Web of Science, and Cochrane Library databases was performed on February 22, 2021. Inclusion criteria were studies with both medical and surgical management comparators, BE diagnosis prior to treatment, patients aged ≥ 18 years, and studies with greater than five patients. Primary outcomes of interest included evaluating changes in histopathologic BE regression and disease progression between interventions. Meta-analysis was performed using a Mantel-Haenszel random-effects model (RevMan 5.4.1). RESULTS A total of 7231 studies were retrieved after initial search with nine studies (1 randomized trial, 7 prospective cohorts, 1 retrospective cohort) meeting final inclusion criteria. Of included studies, 890 (65%) patients received medical management while 470 (35%) received surgical management. Medical management included proton pump inhibitors (n = 807, 91%; 6 studies), H2-receptor blockers (n = 40, 4% patients; 3 studies), and combination therapy (n = 43, 5%; 1 study). Nissen fundoplication was the most commonly performed type of fundoplication (n = 265, 93%). Median length of follow-up ranged from 1.5-7 years. Meta-analysis revealed that fundoplication was associated with improved histopathologic regression of metaplasia/low-grade dysplasia (OR 4.38; 95% CI 2.28-8.42; p < 0.00001) and disease progression to dysplasia/adenocarcinoma (OR 0.34; 95% CI 0.12-0.96; p = 0.04) compared to medical therapy. CONCLUSION Fundoplication is superior to medical therapy with regards to improved odds of histopathologic BE disease regression and disease progression. Additional randomized trials which directly compare medical management and surgical intervention are required to delineate the optimal delivery and timing of these interventions.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) has a high worldwide prevalence in adults and children. There is uncertainty regarding medical versus surgical therapy and different surgical techniques. This review assessed outcomes of antireflux surgery versus medical management of GERD in adults and children, robotic versus laparoscopic fundoplication, complete versus partial fundoplication, and minimal versus maximal dissection in pediatric patients. METHODS PubMed, Embase, and Cochrane databases were searched (2004-2019) to identify randomized control and non-randomized comparative studies. Two independent reviewers screened for eligibility. Random effects meta-analysis was performed on comparative data. Study quality was assessed using the Cochrane Risk of Bias and Newcastle Ottawa Scale. RESULTS From 1473 records, 105 studies were included. Most had high or uncertain risk of bias. Analysis demonstrated that anti-reflux surgery was associated with superior short-term quality of life compared to PPI (Std mean difference = - 0.51, 95%CI - 0.63, - 0.40, I2 = 0%) however short-term symptom control was not significantly superior (RR = 0.75, 95%CI 0.47, 1.21, I2 = 82%). A proportion of patients undergoing operative treatment continue PPI treatment (28%). Robotic and laparoscopic fundoplication outcomes were similar. Compared to total fundoplication, partial fundoplication was associated with higher rates of prolonged PPI usage (RR = 2.06, 95%CI 1.08, 3.94, I2 = 45%). There was no statistically significant difference for long-term symptom control (RR = 0.94, 95%CI 0.85, 1.04, I2 = 53%) or long-term dysphagia (RR = 0.73, 95%CI 0.52, 1.02, I2 = 0%). Ien, minimal dissection during fundoplication was associated with lower reoperation rates than maximal dissection (RR = 0.21, 95%CI 0.06, 0.67). CONCLUSIONS The available evidence regarding the optimal treatment of GERD often suffers from high risk of bias. Additional high-quality randomized control trials may further inform surgical decision making in the treatment of GERD.

Abstract
OBJECTIVE to evaluate esophageal dysmotility (ED) and the extent of Barrett's esophagus (BE) before and after laparoscopic Nissen fundoplication (LNF) in patients previously diagnosed with BE and ED. METHODS twenty-two patients with BE diagnosed by upper gastrointestinal (GI) endoscopy with biopsies and ED diagnosed by conventional esophageal manometry (CEM) were submitted to a LNF, and followed up with clinical evaluations, upper GI endoscopy with biopsies and CEM, for a minimum of 12 months after the surgical procedure. RESULTS : sixteen patients were male (72.7%) and six were females (27.3%). The mean age was 55.14 (± 15.52) years old. and the mean postoperative follow-up was 26.2 months. The upper GI endoscopy showed that the mean length of BE was 4.09 cm preoperatively and 3.91cm postoperatively (p=0.042). The evaluation of esophageal dysmotility through conventional manometry showed that: the preoperative median of the lower esophageal sphincter resting pressure (LESRP) was 9.15 mmHg and 13.2 mmHg postoperatively (p=0.006). The preoperative median of the esophageal contraction amplitude was 47.85 mmHg, and 57.50 mmHg postoperatively (p=0.408). Preoperative evaluation of esophageal peristalsis showed that 13.6% of the sample presented diffuse esophageal spasm and 9.1% ineffective esophageal motility. In the postoperative, 4.5% of patients had diffuse esophageal spasm, 13.6% of aperistalsis and 22.7% of ineffective motor activity (p=0.133). CONCLUSION LNF decreased the BE extension, increased the LES resting pressure, and increased the amplitude of the distal esophageal contraction; however, it was unable to improve ED.

Abstract
BACKGROUND Obesity is associated with a twofold risk of gastroesophageal reflux disease (GERD) and thrice the risk of Barrett's esophagus (BE). Roux-en-Y gastric bypass (RYGB) leads to weight loss and improvement of GERD in population with obesity, but its effect on BE is less clear. METHODS Bibliographic databases were searched systematically for relevant articles till January 31, 2019. Studies evaluating the effect of RYGB on BE with preoperative and postoperative endoscopy and biopsy were included. Study quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) tool. Meta-analysis was conducted using Mantel-Haenszel, random effects model and presented as risk difference (RD) or odds ratio (OR) with 95% confidence intervals. RESULTS Eight studies with 10,779 patients undergoing RYGB reported on 117 patients with BE with follow-up of > 1 year. Significant regression of BE after RYGB was observed (RD - 0.56.95% c.i. - 0.69 to - 0.43; P < 0.001). Subgroup analysis showed regression of both short-segment BE [ssBE] (RD - 0.51.95% c.i. - 0.68 to - 0.33; P < 0.001) and long-segment BE [lsBE] (RD - 0.46.95% c.i. - 0.71 to - 0.21; P < 0.001). RYGB also caused improvement in GERD in patients of BE (RD - 0.93, 95% c.i. - 1.04 to - 0.81; P < 0.001). RYGB was strongly associated with regression of BE compared with progression (OR 31.2.95% c.i. 11.37 to 85.63; P < 0.001). CONCLUSIONS RYGB leads to significant improvement of BE at > 1 year after surgery in terms of regression and resolution of the associated GERD. Both ssBE and lsBE improve after RYGB significantly.

Abstract
Introduction: Adenocarcinoma of the esophagus and cardia is a rare cancer, associated with chronic reflux disease. Its associated mortality is still very high, reflecting both aggressive biology and lack of adequate treatments. The aim of this article was to describe up to date management of these complex tumors. Materials and Methods: A systematic review of the literature was performed, using PubMed Central database. Articles published after the year 2000 were included, with no language exclusion. Results: Reflux disease and Barrett esophagus are strongly associated with esophageal adenocarcinoma. A strict surveillance should be initiated at diagnosis. Both proton pump inhibitors and antireflux surgery failed to influence the incidence of cancer. Surgery and multimodal therapies are keystones for curative treatment, but no clear consensus exists for the best option. A clear trend in standardization of the surgical approach is observed since last ten years. However, the optimal approach for the tumors of the cardia is still not completely set. Complication rate is still high, but real progresses are made, through the implementation of less invasive techniques. Conclusion: Progress has been made in the management of esophageal cancer. However, the multiplicity of choices failed to lead to standardization. The development of international consensus regarding multimodal treatment and surgical approaches is needed.

Abstract
Background: Re-fundoplication is the most often procedure performed after failed fundoplication, but re-failure is even higher. Aim: The objectives are: a) to discuss the results of fundoplication and re-fundoplication in these cases, and b) to analyze in which clinical situation there is a room for gastrectomy after failed fundoplication. Method: This experience includes 104 patients submitted to re-fundoplication after failure of the initial operation, 50 cases of long segment Barrett´s esophagus and 60 patients with morbid obesity, comparing the postoperative outcome in terms of clinical, endoscopic, manometric and 24h pH monitoring results. Results: In patients with failure after initial fundoplication, redo-fundoplication shows the worst clinical results (symptoms, endoscopic esophagitis, manometry and 24 h pH monitoring). In patients with long segment Barrett´s esophagus, better results were observed after fundoplication plus Roux-en-Y distal gastrectomy and in obese patients similar results regarding symptoms, endoscopic esophagitis and 24h pH monitoring were observed after both fundoplication plus distal gastrectomy or laparoscopic resectional gastric bypass, while regarding manometry, normal LES pressure was observed only after fundoplication plus distal gastrectomy. Conclusion: Distal gastrectomy is recommended for patients with failure after initial fundoplication, patients with long segment Barrett´s esophagus and obese patients with gastroesophageal reflux disease and Barrett´s esophagus. Despite its higher morbidity, this procedure represents an important addition to the surgical armamentarium.

Abstract
Barrett's esophagus (BE) is the only known precursor of esophageal adenocarcinoma, one of the few cancers with increasing incidence in developed countries. The pathogenesis of BE is unclear with regard to either the cellular origin of this metaplastic epithelium or the manner in which malignant transformation occurs, although recent data indicate a possible junctional origin of stem cells for BE. Treatment of BE may be achieved using endoscopic eradication therapy; however, there is a lack of discriminatory tools to identify individuals at sufficient risk for cancer development in whom intervention is warranted. Reduction in gastroesophageal reflux of gastric contents including acid is mandatory to achieve remission from BE after endoscopic ablation, and can be achieved using medical or nonmedical interventions. Research topics of greatest interest include the mechanism of BE development and transformation to cancer, risk stratification methods to identify individuals who may benefit from ablation of BE, optimization of eradication therapy, and surveillance methods to ensure that remission is maintained after eradication is achieved.

Patients With Barrett's Esophagus and Confirmed Persistent Low-Grade Dysplasia Are at Increased Risk for Progression to Neoplasia. Gastroenterology 2017; 152:993-1001.e1. [PMID: 28012849 DOI: 10.1053/j.gastro.2016.12.008] [Citation(s) in RCA: 75] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2016] [Revised: 12/01/2016] [Accepted: 12/12/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS For patients with Barrett's esophagus, the diagnosis of low-grade dysplasia (LGD) is subjective, and reported outcomes vary. We analyzed data from a multicenter study of endoscopic therapy to identify factors associated with progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) in patients with LGD of the esophagus. METHODS We performed a retrospective analysis of data from 255 patients with a primary diagnosis of LGD (78% men; mean age, 63 years) who participated in a randomized controlled trial of surveillance vs radiofrequency ablation in Europe. Three expert pathologists independently reviewed baseline and subsequent LGD specimens. The presence and degree of dysplasia was separately recorded for each biopsy and classified according to the Vienna Classification system. The primary end point was development of HGD or EAC. We performed univariate logistic regression analyses to assess the association between outcomes and factors such as number of pathologists confirming LGD, multifocality of LGD, and persistence of LGD over time. RESULTS Of the 255 patients, 45 (18%) developed HGD or EAC during a median 42-month follow-up period (interquartile range, 25-61 months); patients were examined by a median 4 endoscopies (interquartile range, 3-6 endoscopies). The number of pathologists confirming LGD was strongly associated with progression to neoplasia; risk for progression increased greatly when all 3 pathologists agreed on LGD (odds ratio, 47.14; 95% confidence interval, 13.10-169.70). When LGD was detected at baseline and confirmed by a subsequent endoscopy, the odds for progression to neoplasia also increased greatly (odds ratio, 9.28; 95% confidence interval, 4.39-19.64). Multifocal LGD was not significantly associated with progression to neoplasia. CONCLUSIONS The number of pathologists confirming LGD and persistence of LGD over time increase risk for development of HGD or EAC in patients with Barrett's esophagus and LGD. These simple, readily available variables can help stratify risk and select patients for prophylactic ablation therapy.

[PMID: 27553805 DOI: 10.1007/s00464-016-5184-3] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2016] [Accepted: 08/12/2016] [Indexed: 12/27/2022]
Abstract
INTRODUCTION Barrett's esophagus (BE) is recognized as a premalignant lesion for esophageal adenocarcinoma. BE appears as a consequence of gastroesophageal reflux disease (GERD), which is increased among obese population. Laparoscopic Roux-en-Y gastric bypass (LRYGB) is the best treatment option for obesity combined with GERD. However, data on evolution of BE after LRYGB are scarce. METHODS AND PROCEDURES Patients were studied with esophagogastroduodenoscopy (EGD) and gastric biopsy preoperatively. If BE was suspected, esophageal biopsy was performed. If BE was confirmed, LRYGB was indicated with yearly surveillance EGD with biopsies. LRYGB patients who had BE with at least 1-year follow-up were included. RESULTS Between 10/07 and 1/16, 2144 patients underwent laparoscopic bariatric surgery at our institution. There were 1681 (78 %) LRYGB, 399 (19 %) laparoscopic sleeve gastrectomies, and 64 (3 %) revisions. Nineteen patients (0.9 %) had BE preoperatively, and they all underwent LRYGB; 11 of them (58 %) were eligible for this study. There were 6 women and 5 men, mean age 49 ± 11 years, initial BMI 44 ± 6 kg/m2. Mean follow-up was 41 ± 31 months; there were 9 short-segment BE (SSBE) and 2 long-segment BE (LSBE). On pre- and post-op EGD, BE length was 2.1 ± 1.6 and 1.2 ± 1.2 cm, respectively (p = NS). Post-op EGD was compatible with BE in all cases, although esophageal biopsy showed remission in 4 (36 %) cases: three short-segment BE (SSBE) and one long-segment BE (LSBE). One patient was indefinite for dysplasia and remained the same after the operation. CONCLUSION Our preliminary data showed that LRYGB is a suitable treatment option for obese patients with BE, demonstrated by 36 % regression rate of this premalignant disease. Although BE persisted in the remaining patients, no progression to dysplasia was observed. A larger number of patients and longer follow-up are needed for more definitive conclusions.

Antireflux Surgery and Risk of Esophageal Adenocarcinoma: A Systematic Review and Meta-analysis. Ann Surg 2016; 263:251-7.

Abstract
OBJECTIVE To investigate the preventive effect of antireflux surgery against esophageal adenocarcinoma (EAC) compared with medical treatment of gastroesophageal reflux disease (GERD) and to the background population. BACKGROUND GERD is causally associated with EAC. Effective symptomatic treatment can be achieved with medication and antireflux surgery; however the possible preventive effect on EAC development remains unclear. METHODS This systematic review identified 10 studies comparing EAC risk after antireflux surgery with nonoperated GERD patients, including 7 studies of patients with Barrett's esophagus, and 2 studies comparing EAC risk after antireflux surgery to the background population. A fixed-effects Poisson meta-analysis was conducted to calculate pooled incidence rate ratios (IRR) and 95% confidence intervals (CIs). RESULTS The pooled IRR in patients after antireflux surgery was 0.76 (95% CI 0.42-1.39) compared with medically treated GERD patients. In patients with Barrett's esophagus, the corresponding IRR was 0.46 (95% CI 0.20-1.08), and 0.26 (95% CI 0.09-0.79) when restricted to publications after 2000. There was no difference in EAC risk between antireflux surgery and medical treatment in GERD patients without known Barrett's esophagus (IRR 0.98, 95% CI 0.72-1.33). The EAC risk remained elevated in patients after antireflux surgery compared with the background population (IRR 10.78, 95% CI 8.48-13.71). Although the clinical heterogeneity of the included studies was high, the statistical heterogeneity was low. CONCLUSIONS Antireflux surgery may prevent EAC better than medical therapy in patients with Barrett's esophagus. The EAC risk after antireflux surgery does not seem to revert to that of the background population.

Abstract
Although there are many unanswered questions with Barrett esophagus, we can safely say that the incidence is increasing, chemoprevention strategies for the prevention of Barrett metaplasia and its progression to adenocarcinoma may be in the offing, surveillance should be considered for all patients who are discovered to have Barrett esophagus, RFA is the treatment of choice for those with HGD and strongly considered in those with LGD, EMR should be the treatment of choice for patients with nodular high-grade Barrett esophagus, and, finally, vagal-sparing esophagectomy reserved for patients with persistent HGD or a strong suspicion of carcinoma, with consideration of a concomitant fundoplication.

Abstract
Patients with gastroesophageal reflux disease and Barrett's esophagus can be a management challenge for the treating physician or surgeon. The goals of therapy include relief of reflux symptoms, induction of histologic regression, and prevention of progression of intestinal metaplasia to dysplasia or invasive carcinoma. Antireflux surgery is effective at achieving these end points, although ongoing follow-up and endoscopic surveillance are essential. In cases of dysplasia or early esophageal neoplasia associated with Barrett's esophagus, endoscopic resection and ablation have supplanted esophagectomy as the standard of care in most cases. Esophageal resection continues to have a role, however, in a minority of appropriately selected candidates.

Abstract
OBJECTIVES Barrett's esophagus (BE) is a common premalignant lesion for which surveillance is recommended. This strategy is limited by considerable variations in clinical practice. We conducted an international, multidisciplinary, systematic search and evidence-based review of BE and provided consensus recommendations for clinical use in patients with nondysplastic, indefinite, and low-grade dysplasia (LGD). METHODS We defined the scope, proposed statements, and searched electronic databases, yielding 20,558 publications that were screened, selected online, and formed the evidence base. We used a Delphi consensus process, with an 80% agreement threshold, using GRADE (Grading of Recommendations Assessment, Development and Evaluation) to categorize the quality of evidence and strength of recommendations. RESULTS In total, 80% of respondents agreed with 55 of 127 statements in the final voting rounds. Population endoscopic screening is not recommended and screening should target only very high-risk cases of males aged over 60 years with chronic uncontrolled reflux. A new international definition of BE was agreed upon. For any degree of dysplasia, at least two specialist gastrointestinal (GI) pathologists are required. Risk factors for cancer include male gender, length of BE, and central obesity. Endoscopic resection should be used for visible, nodular areas. Surveillance is not recommended for <5 years of life expectancy. Management strategies for indefinite dysplasia (IND) and LGD were identified, including a de-escalation strategy for lower-risk patients and escalation to intervention with follow-up for higher-risk patients. CONCLUSIONS In this uniquely large consensus process in gastroenterology, we made key clinical recommendations for the escalation/de-escalation of BE in clinical practice. We made strong recommendations for the prioritization of future research.

Clin Gastroenterol Hepatol 2015; 13:459-465.e1.

Abstract
BACKGROUND & AIMS In patients with Barrett's esophagus (BE), low-grade dysplasia (LGD) is a risk factor for esophageal adenocarcinoma (EAC), progressing at variable rates. Patients at higher risk for progression could benefit from intervention. We assessed rates of progression of LGD and indefinite for dysplasia (IND) and risk factors for progression to high-grade dysplasia (HGD) and EAC. METHODS We analyzed data from Cleveland Clinic Barrett's Registry on patients with BE and LGD or IND at least 1 year of follow-up from January 1, 2002 through December 31, 2012. Prevalent cases were those diagnosed at or within 1 year of the first endoscopy, and the rest were incident cases. RESULTS Among 299 patients with BE and LGD or IND, there were 32 cases of HGD and 10 cases of EAC during a follow-up period of 1577.4 patient-years. The annual incidence rates were 2.4% (95% confidence interval [CI], 1.7%-3.3%) for HGD, 0.6% (95% CI, 0.3%-1.2%) for EAC, and 2.7% (95% CI, 1.9%-3.6%) for HGD or EAC. The rates were higher in men than in women with BE and LGD or IND. Prevalent cases were 3-fold more likely to progress than incident cases. Multifocality and nodules were associated with higher risk of progression to HGD or EAC. None of the patients with IND at index biopsy developed EAC. For every 5-year increase in age, chance of regression increased by 7% (P = .04). Also, for every 1-cm increase in BE length, probability of regression decreased by 6% (P = .016). LGD at index biopsy was associated with 56% lower chance of regression compared with IND (P < .001). CONCLUSIONS On the basis of a database analysis of patients with BE, prevalent LGD, male sex, multifocality, and nodules were associated with higher risk for progression to EAC. Older age at LGD diagnosis, IND at index biopsy, and shorter BE length were associated with regression. These findings help in risk stratification of patients with BE and LGD or IND.

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

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is probably one of the most prevalent diseases in the world that also compromises the quality of life of the affected significantly. Its incidence in Brazil is 12%, corresponding to 20 million individuals. OBJECTIVE To update the GERD management and the new trends on diagnosis and treatment, reviewing the international and Brazilian experience on it. METHOD The literature review was based on papers published on Medline/Pubmed, SciELO, Lilacs, Embase and Cochrane crossing the following headings: gastroesophageal reflux disease, diagnosis, clinical treatment, surgery, fundoplication. RESULTS Various factors are involved on GERD physiopathology, the most important being the transient lower esophageal sphincter relaxation. Clinical manifestations are heartburn, regurgitation (typical symptoms), cough, chest pain, asthma, hoarseness and throat clearing (atypical symptoms), which may be followed or not by typical symptoms. GERD patients may present complications such as peptic stenosis, hemorrhage, and Barrett's esophagus, which is the most important predisposing factor to adenocarcinoma. The GERD diagnosis must be based on the anamnesis and the symptoms must be evaluated in terms of duration, intensity, frequency, triggering and relief factors, pattern of evolution and impact on the patient's quality of life. The diagnosis requires confirmation with different exams. The goal of the clinical treatment is to relieve the symptoms and surgical treatment is indicated for patients who require continued drug use, with intolerance to prolonged clinical treatment and with GERD complications. CONCLUSION GERD is a major digestive health problem and affect 12% of Brazilian people. The anamnesis is fundamental for the diagnosis of GERD, with special analysis of the typical and atypical symptoms (duration, intensity, frequency, triggering and relief factors, evolution and impact on the life quality). High digestive endoscopy and esophageal pHmetry are the most sensitive diagnosctic methods. The clinical treatment is useful in controlling the symptoms; however, the great problem is keeping the patients asymptomatic over time. Surgical treatment is indicated for patients who required continued drug use, intolerant to the drugs and with complicated forms of GERD.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett's esophagus, and enteroesophageal and duodenogastroesophageal reflux. METHODS The European Association of Endoscopic Surgery (EAES) has tasked a group of experts, based on their clinical and scientific expertise in the field of GERD, to establish current guidelines in a consensus development conference. The expert panel was constituted in May 2012 and met in September 2012 and January 2013, followed by a Delphi process. Critical appraisal of the literature was accomplished. All articles were reviewed and classified according to the hierarchy of level of evidence and summarized in statements and recommendations, which were presented to the scientific community during the EAES yearly conference in a plenary session in Vienna 2013. A second Delphi process followed discussion in the plenary session. RESULTS Recommendations for pathophysiologic and epidemiologic considerations, symptom evaluation, diagnostic workup, medical therapy, and surgical therapy are presented. Diagnostic evaluation and adequate selection of patients are the most important features for success of the current management of GERD. Laparoscopic fundoplication is the most important therapeutic technique for the success of surgical therapy of GERD. CONCLUSIONS Since the background of GERD is multifactorial, the management of this disease requires a complex approach in diagnostic workup as well as for medical and surgical treatment. Laparoscopic fundoplication in well-selected patients is a successful therapeutic option.

Abstract
Barrett's esophagus, the condition in which metaplastic columnar epithelium that predisposes to cancer development replaces the squamous epithelium that normally lines the distal esophagus, is a complication of gastroesophageal reflux disease (GERD). Metaplasia is a potentially reversible condition, and partial regression of Barrett's metaplasia has been documented with effective medical or surgical therapy for GERD. The important issue for patient management is not whether antireflux treatment causes Barrett's esophagus to regress, but rather whether antireflux therapy prevents cancer in Barrett's esophagus. Proton pump inhibitors (PPIs) would be expected to prevent this cancer because they heal reflux esophagitis, reduce exposure to a potential carcinogen (acid), and might prevent acid-induced proliferation and cancer-promoting cytokine secretion by esophageal epithelial cells. Furthermore, observational studies have shown that PPI use is associated with a decreased incidence of neoplasia in Barrett's esophagus. In theory, successful antireflux surgery, which eliminates the reflux of both acid and bile, should be better for cancer prevention than medical therapy, which only decreases the reflux of acid. However, high-quality studies show no significant difference in cancer incidence between medically and surgically treated patients with GERD and Barrett's esophagus. Furthermore, for individual patients with nondysplastic Barrett's metaplasia, the cancer risk is so small and the number needed to treat for cancer prevention with surgery so large, that it does not matter whether or not surgery provides a tiny margin of extra protection against cancer beyond that provided by medical therapy. The cost and risks of the operation overwhelm any small, additional cancer protective benefit. Antireflux surgery is very effective at controlling the endoscopic signs and symptoms of GERD, but the operation should not be recommended to patients solely with the rationale that it protects against cancer better than medical therapy.

Abstract
BACKGROUND Treatment of esophageal adenocarcinoma often involves surgical resection. Newer technologies in interventional endoscopy have led to a substantial paradigm shift in the management of early-stage neoplasia in Barrett's esophagus comprising high-grade dysplasia (HGD), intramucosal carcinoma, and, in some cases, submucosal carcinoma. However, there has been no consensus regarding the indications for esophageal preservation in these cases. In this work, consensus guidelines were established for the management of early-stage esophageal neoplasia considering clinically relevant aspects (age, comorbidities, and social environment) in each scenario. METHODS Seventeen experts were invited to participate based on their background and clinical expertise at high-volume centers. A questionnaire was created that included four clinical scenarios covering a wide range of situations within HGD and/or early esophageal neoplasia, particularly where controversies are likely to exist. Each of the clinical scenarios was open to discussion subdivided by patient age (20, 50, and 80 s). For each clinical scenario an expert was chosen to defend that position. Each defense triggered a subsequent discussion during a consensus meeting. Conclusions of that discussion together with an accompanying literature analysis allowed experts to confirm or change their original choices and served as the basis for the recommendations stated in this article. RESULTS There was 100 % consensus supporting esophageal preservation in patients with HGD, independent of patient age or Barrett's length. In patients with T1a adenocarcinoma, consensus for preservation was not reached (65 %) for young and middle-aged individuals but was supported for elderly patients (100 %). For T1b adenocarcinoma, consensus was reached for surgical resection (90 %), leaving organ preservation for patients with very low risk of nodal invasion or poor surgical candidates. CONCLUSION Advances in endoscopic imaging and therapy allow for organ preservation in most settings of early-stage neoplasia of the esophagus, provided that the patient understands the implications of this decision.

Abstract
Barrett's esophagus is a pathologic change of the normal squamous epithelium of the esophagus to specialized columnar metaplasia. Barrett's esophagus is a result of prolonged exposure of the esophagus to gastroduodenal refluxate. Although Barrett's itself is not symptomatic, and, in fact, patients with Barrett's esophagus may be completely asymptomatic, it does identify patients at higher risk of developing esophageal adenocarcinoma. Traditionally, antireflux surgery was reserved for patients with symptoms, because it was believed that antireflux surgery did not eliminate Barrett's esophagus and reduce cancer risk. Rationale for the treatment of Barrett's esophagus beyond treating symptoms of gastroesophageal reflux disease stems from the hope to decrease, if not eliminate, the risk of adenocarcinoma. Treatment options ranged from medical acid suppression without surveillance to resection. Ablation, particularly endoscopic radio-frequency ablation, has become the standard of care for Barrett's esophagus with high-grade dysplasia. It role in nondysplastic or low-grade dysplastic Barrett's is less clear. Combined endoscopic mucosal resection with ablation is effective in nodular high-grade Barrett's esophagus. Resection should be reserved for patients with persistent high-grade dysplasia despite multiple attempts at endoscopic ablation or resection or for patients with evidence of carcinoma.

Abstract
Introduction. The objective of this study was to evaluate Ki-67 antigen expression in patients with Barrett's esophagus and esophageal adenocarcinoma and to assess its correlation with the metaplasia-esophageal adenocarcinoma progression. Methods. Using immunohistochemistry we evaluated the Ki-67 index in patients with Barrett's esophagus, esophageal adenocarcinoma, and controls. We included patients with endoscopically visible columnar mucosa of the distal esophagus (whose biopsies revealed specialized intestinal-type metaplasia), patients with esophageal and esophagogastric tumors types I and II, and patients with histologically normal gastric mucosa (control). Results. In the 57 patients studied there were no statistically significant differences between the groups with respect to age or race. Patients with cancer were predominantly men. The Ki-67 index averaged 10 ± 4
% in patients with normal gastric mucosa (n = 17), 21 ± 15
% in patients with Barrett's esophagus (n = 21), and 38 ± 16
% in patients with cancer (n = 19).
Ki-67 expression was significantly different between all groups (P < 0.05).
There was a strong linear correlation between Ki-67 expression and the metaplasia-adenocarcinoma sequence (P < 0.01).
In patients with cancer, Ki-67 was not associated with clinical or surgical staging. Conclusions. Ki-67 antigen has increased expression along the metaplasia-adenocarcinoma sequence. There is a strong linear correlation between Ki-67 proliferative activity and Barrett's carcinogenesis.

Abstract
AIM A multipotential stem cell, possibly located in the submucosal gland ducts, has been suggested as the origin of metaplastic mucosa in the oesophagus. The topographic distribution of these glands and their excretory ducts (SMG) within the columnar lined oesophagus (CLO) is largely unknown. The aim of this study was to examine the distribution of SMG in relation to the type of overlying epithelium in patients with CLO. METHODS AND RESULTS Seven oesophageal resection specimens were examined histologically in toto. The median frequency of SMG was similar in the metaplastic segments (0.12 SMG/mm) and the normal squamous segments (0.10 SMG/mm). Within the metaplastic segments, the median frequency of SMG beneath the squamous islands was significantly higher than that observed under the columnar lined parts (0.22 versus 0.08 SMG/mm, P = 0.046), There was a strong accumulation of SMG at the squamo-columnar transition zones (0.53 SMG/mm), which was significantly greater than that found in the columnar and squamous parts (P = 0.001 and 0.002, respectively). CONCLUSIONS The relative accumulation of SMG beneath squamous islands and the squamo-columnar junctions within the metaplastic segment supports the hypothesis that both metaplastic columnar mucosa and neosquamous epithelium originate from a progenitor in the SMG.

Abstract
BACKGROUND Barrett's esophagus (BE) is the most serious complication of GERD. In BE patients, this observational study compares the effects of antireflux surgery versus antisecretory medical therapy. METHODS Overall, 89 BE patients (long BE = 45; short BE = 44) were considered: 45 patients underwent antireflux surgery and 44 underwent medical therapy. At both initial and follow-up endoscopy, symptoms were assessed using a detailed questionnaire; BE phenotypic changes [intestinal metaplasia (IM) presence/type, Cdx2 expression] were assessed by histology (H&E), histochemistry (HID), and immunohistochemistry. Surgical failures were defined as follows: (1) abnormal 24-h pH monitoring results after surgery, (2) endoscopically evident recurrent esophagitis, and (3) recurrent hiatal hernia or slipped fundoplication on endoscopy or barium swallow. RESULTS Reversion of IM was observed in 12/44 SSBE and 0/45 LSBE patients (p < 0.01). Reversion was more frequently observed after effective antireflux surgery than after medical treatment (p = 0.04). In patients with no further evidence of IM after therapy, Cdx2 expression was also absent (p = 0.02). The extent of IM was reduced, and the IM phenotype improved in SSBE patients after surgery. CONCLUSIONS Patients with short BE (but not those with long BE) may benefit from surgically reducing the esophagus' exposure to GE reflux; among these patients, successful surgery carries a higher IM reversion rate than medical treatment.

Abstract
OBJECTIVE The aim of our study was to conduct a retrospective investigation of the efficacy of laparoscopic Nissen fundoplication in patients with Barrett's esophagus. MATERIAL AND METHODS A total of 78 patients with Barrett's esophagus underwent surgery. Patients were divided into three groups on the basis of the preoperative endoscopic biopsies: a non-intestinal group (n = 63) with fundic or cardiac metaplasia, an intestinal group (n = 18) with intestinal metaplasia, and a dysplastic group (n = 7) with low-grade dysplasia. Clinical follow-up was available in the case of 64 patients at a mean of 42 ± 16.9 months after surgery. RESULTS Check-up examination revealed total regression of Barrett's metaplasia in 10 patients. Partial regression was seen in 9 cases, no further progression in 34 patients, and progression into cardiac or intestinal metaplasia in 11 patients. No cases of dysplastic or malignant transformation were registered. Where we observed the regression of BE, among the postoperative functional examinations results of manometry (pressure of lower esophageal sphincter) and pH-metry were significantly better compared with those groups where no changes occurred in BE, or progression of BE was found. Discussion. Our results highlight the importance of the cases of fundic and cardiac metaplasia, which can also transform into intestinal metaplasia. CONCLUSIONS Antireflux surgery can appropriately control the reflux disease in a majority of the patients who had unsuccessful medical treatment, and it may inhibit the progression and induce the regression of Barrett's metaplasia in a significant proportion of these patients.

Abstract
INTRODUÇÃO: O adenocarcinoma de esôfago apresenta aumento de frequência nas últimas décadas, particularmente em países desenvolvidos. O esôfago de Barrett é reconhecido como a principal lesão precursora e o estudo da sequência metaplasia-displasia-adenocarcinoma mostra a ocorrência de alterações genéticas desde suas fases mais incipientes. As alterações no p16INK4a são relatadas como frequentes no esôfago de Barrett e no carcinoma de esôfago. OBJETIVO: Verificar a prevalência da expressão imunoistoquímica da proteína p16INK4a em exames anatomopatológicos de pacientes com adenocarcinoma de esôfago. MÉTODO: A população do estudo foi constituída de 37 pacientes com adenocarcinoma de esôfago. A expressão da proteína p16 foi detectada por meio de análise imunoistoquímica, com anticorpo primário p16INK4aAb-7, clone 16P07, NeoMarkers e avaliada de acordo com o Sistema de Escore de Imunorreatividade (Immunoreactive scoring system - IRS) modificado. RESULTADOS: No grupo houve predominância de pacientes do sexo masculino (86,5%) e a maioria dos casos correspondia a estádios avançados (III e IV = 67,5%). Em 12 casos (32,4%) foi identificada expressão imunoistoquímica da proteína p16INK4a. Não foi observada relação significativa entre a perda da expressão da proteína p16INK4a e o grau de diferenciação histológica (p=0,81) nem com o estadiamento da doença (p=0,485). CONCLUSÃO: Ocorre perda da expressão imunoistoquímica da proteína p16INK4a, corroborando as informações de que a inativação do gene p16 é um evento frequente e que pode exercer papel importante na carcinogênese do adenocarcinoma de esôfago.

Abstract
Laparoscopic antireflux surgery is very successful in patients with short-segment Barrett's esophagus (BE), but in patients with long-segment BE, the results remain in discussion. In these patients, during the open era of surgery, we performed acid suppression + duodenal diversion procedures added to the antireflux procedure (fundoplication + vagotomy + antrectomy + Roux-en-Y gastrojejunostomy) to obtain better results at long-term follow-up. The aim of this prospective study is to present the results of 3 to 5 years' follow-up in patients with short-segment and long-segment or complicated BE (ulcer or stricture) who underwent fundoplication or the acid suppression-duodenal diversion technique, both performed by a laparoscopic approach. One hundred eight patients with histologically confirmed BE were included: 58 patients with short-segment BE, and 50 with long-segment BE, 28 of whom had complications associated with severe erosive esophagitis, ulcer, or stricture. After surgery, among patients treated with fundoplication with cardia calibration, endoscopic erosive esophagitis was observed in 6.9% of patients with short-segment BE, while 50% of patients with long-segment BE presented with positive acid reflux, persistence of endoscopic esophagitis with intestinal metaplasia, and progression to dysplasia (in 5% of cases; P = 0.000). On the contrary, after acid suppression-duodenal diversion surgery in patients with long-segment BE, more than 95.6% presented with successful results regarding recurrent symptoms and endoscopic regression of esophagitis. Regression of intestinal metaplasia to the cardiac mucosa was observed in 56.9% of patients with short-segment BE who underwent fundoplication and in 61% of those with long-segment BE treated with the acid suppression-duodenal diversion procedure. Patients with long-segment BE who experienced fundoplication alone presented no regression of intestinal metaplasia; on the contrary, progression to dysplasia was observed in 1 case (P = 0.049). Patients with short-segment BE can be successfully treated with fundoplication, but for patients with long-segment BE, we suggest performance of fundoplication plus an acid suppression-duodenal diversion procedure.

Abstract
High-grade dysplasia (HGD) in Barrett’s esophagus (BE) is the critical step before invasive esophageal adenocarcinoma. Although its natural history remains unclear, an aggressive therapeutic approach is usually indicated. Esophagectomy represents the only treatment able to reliably eradicate the neoplastic epithelium. In healthy patients with reasonable life expectancy, vagal-sparing esophagectomy, with associated low mortality and low early and late postoperative morbidity, is considered the treatment of choice for BE with HGD. Patients unfit for surgery should be managed in a less aggressive manner, using endoscopic ablation or endoscopic mucosal resection of the entire BE segment, followed by lifelong surveillance. Patients eligible for surgery who present with a long BE segment, multifocal dysplastic lesions, severe reflux symptoms, a large fixed hiatal hernia or dysphagia comprise a challenging group with regard to the appropriate treatment, either surgical or endoscopic.

Abstract
Dysplasia and esophageal adenocarcinoma may arise in patients with Barrett's esophagus after fundoplication esophageal pH monitoring showing no acid in esophagus. This suggests the need to develop methodology to evaluate the occurrence of ultra-distal reflux (1cm above the LES). The objective of the study was to compare acid exposition in three different levels: 5cm above the upper border of the LES, 1cm above the LES and in the intrasphincteric region. Eleven patients with Barrett's esophagus after Nissen fundoplication with no clinical, endoscopic and radiologic evidence of reflux were selected. Four-channel pH monitoring took place: channel A, 5cm above the upper border of the LES; channel B, 1cm above the LES; channel C, intrasphincteric; channel D, intragastric. The results of channels A, B and C were compared. There was significant increase in number of reflux episodes and a higher fraction of time with pH <4.0 in channel B compared to channel A. There was significant decrease in fraction of time with pH <4.0 in channel B compared to channel C. Two cases of esophageal adenocarcinoma were diagnosed in the studied patients. The region 1cm above the upper border of the LES is more exposed to acid than the region 5cm above the upper border of the LES, although this exposure occurred in reduced levels. The region 1cm above the upper border of the LES is less exposed to acid than the intrasphincteric region.

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

Abstract
BACKGROUND Factors associated with the risk of progression of Barrett's esophagus remain unclear, and the impact of therapy on this risk remains uncertain. The aim of this study was to assess patients followed long-term after anti-reflux surgery for Barrett's esophagus. METHODS A retrospective review was performed of all patients with Barrett's who underwent anti-reflux surgery from 1989 to 2009 and had ≥5 years of follow-up. RESULTS There were 303 patients and 75 had follow-up ≥5 years. Median follow-up time for the 75 patients was 8.9 years (range 5-18). Regression was seen in 31%. Progression occurred in 8%, and these patients were significantly more likely to have a failed fundoplication (67% vs. 16%, p = 0.0129). The rate of progression from non-dysplastic Barrett's to high-grade dysplasia or cancer was 0.8% per patient year, and was seven times higher in patients with a failed fundoplication. CONCLUSION Compared to the accepted rate of progression of non-dysplastic Barrett's to high-grade dysplasia or cancer of 1.0% per patient year, anti-reflux surgery reduces this rate during long-term follow-up. The rate of progression was significantly lower in patients with an intact compared to a disrupted fundoplication, further suggesting that anti-reflux surgery can alter the natural history of Barrett's esophagus.

Abstract
Barrett’s esophagus (BE) is a change in the esophageal mucosa as a result of long-standing gastroesophageal reflux disease. The importance of BE is that it is the main risk factor for the development of esophageal adenocarcinoma, whose incidence is currently growing faster than any other cancer in the Western world. The aim of this review was to compare the common treatment modalities of BE, with the focus on proton pump inhibitors and operative fundoplication. We performed a literature search on medical and surgical treatment of BE to determine eligible studies for this review. Studies on medical and surgical treatment of BE are discussed with regard to treatment effect on progression and regression of disease. Although there is some evidence for control of reflux with either medical or surgical therapy, there is no definitive evidence that either treatment modality decreases the risk of progression to dysplasia or cancer. Even though there is a trend toward antireflux surgery being superior, there are no definitive studies to prove this.

Abstract
Gastroesophageal reflux disease (GERD) affects an estimated 20% of the population in the United States. About 10%-15% of patients with GERD develop Barrett’s esophagus, which can progress to adenocarcinoma, currently the most prevalent type of esophageal cancer. The esophagus is normally lined by squamous mucosa, therefore, it is clear that for adenocarcinoma to develop, there must be a sequence of events that result in transformation of the normal squamous mucosa into columnar epithelium. This sequence begins with gastroesophageal reflux, and with continued injury metaplastic columnar epithelium develops. This article reviews the pathophysiology of Barrett’s esophagus and implications for its treatment. The effect of medical and surgical therapy of Barrett’s esophagus is compared.

Immunohistochemical evaluation for P53 and VEGF (Vascular Endothelial Growth Factor) is not prognostic for long term survival in end stage esophageal adenocarcinoma. Rev Col Bras Cir 2010; 36:24-34. [PMID: 20076865 DOI: 10.1590/s0100-69912009000100007] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2008] [Accepted: 10/28/2008] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVES To correlate the expression of p53 protein and VEGF with the prognosis of patients submitted to curative resection to treat esophageal adenocarcinoma. METHODS Forty-six patients with esophageal adenocarcinoma, submitted to curative resection, were studied. The expressions of p53 protein and VEGF were assessed by immunohistochemistry in 52.2% and 47.8% of tumors, respectively. RESULTS P53 protein and VEGF expressions coincided in 26% of the cases, and no correlation between these expressions was observed. None of the clinicopathological factors showed a significant correlation with p53 protein or VEGF expressions. There was no significant association between p53 protein and VEGF expressions and long-term survival. CONCLUSION The expression of p53 protein and VEGF did not correlate with prognosis in esophageal adenocarcinoma patients submitted to curative resection.
