Abstract
BACKGROUND Redo fundoplication has acceptable outcomes in patients with failed previous fundoplications. However, a subset of patients require Roux-en-Y (RNY) reconstruction for symptom relief. AIM The aim of this study was to demonstrate safety and efficacy of RNY reconstruction for failed fundoplications. METHOD Retrospective review of data on patients who underwent short-limb RNY gastrojejunostomy (GJ) or esophagojejunostomy (EJ) between the years 2005 and 2007 was performed. RESULTS Twenty-two patients underwent RNY reconstructions. Fourteen (64%) patients had one, six (27%) patients had two, and 2 (9%) patients had three previous anti-reflux procedures. RNY GJ was performed in 18 patients and EJ in four patients. Gastrectomy was performed in 13 of these patients. Seven patients (32%) had ten major or minor complications within the 30-day postoperative period, without any mortality observed. At a mean follow-up of 23 months, completed in 21 of these patients (95%), the average heartburn score was 0.38 (range, 0-2). The average regurgitation score was 0.23 (range, 0 to2) and the average dysphagia score was 0.7 (range, 0-2). The mean postoperative BMI was 25.4 compared to a preoperative BMI of 31. CONCLUSION RNY reconstruction with GJ or EJ for failed anti-reflux procedures is a safe, valid surgical option in difficult situations, where a redo fundoplication is either non-feasible or expected to fail. However, it is associated with higher morbidity.

Abstract
AIMS To evaluate the efficacy of duodenal switch operation for patients with duodeno-gastroesophageal reflux disease. METHODS Four female patients with therapy resistant epigastric pain and biliary regurgitation were enrolled in the study. In all cases, abnormal duodeno-gastric reflux was confirmed by 24-hour Bilitec monitoring. The average age of the patients was 41.75 years (range 32-53) and three of them had a cholecystectomy in the past. Importantly, all patients had previously undergone fundoplication, which had to be repeated in one of them due to recurrent symptoms. More recently, a duodenal switch procedure was performed in these four patients. Their mean follow-up time was 24.25 months (range 21-30). RESULTS Duodenal switch was performed without any perioperative complications. A good clinical outcome was found in all patients on their follow up; however, an abnormal acidic exposure was found in one case on 24-hour oesophageal pH monitoring. CONCLUSION Recurrent epigastric complaints developing after anti-reflux surgery in patients with a previous diagnosis of gastroesophageal reflux disease might be due to an abnormal duodeno-gastric reflux. Previous cholecystectomy may increase the risk of biliary reflux. Duodenal switch procedure can be applied with good results in patients with therapy resistant abnormal duodeno-gastric reflux confirmed with Bilitec monitoring.

Abstract
OBJECTIVE To determine whether patients with Barrett esophagus who undergo antireflux surgery differ from medically treated patients in incidence of esophageal adenocarcinoma and probability of disease regression/progression. SUMMARY BACKGROUND DATA Barrett esophagus is a risk factor for the development of esophageal adenocarcinoma. A question exists as to whether antireflux surgery reduces this risk. METHODS Query of PubMed (1966 through October 2005) using predetermined search terms revealed 2011 abstracts, of which 100 full-text articles were reviewed. Twenty-five articles met selection criteria. A review of article references and consultation with experts revealed additional articles for inclusion. Studies that enrolled adults with biopsy-proven Barrett esophagus, specified treatment-type rendered, followed up patients with endoscopic biopsies no less than12 months of instituting therapy, and provided adequate extractable data. The incidence of adenocarcinoma and the proportion of patients developing progression or regression of Barrett esophagus and/or dysplasia were extracted. RESULTS In surgical and medical groups, 700 and 996 patients were followed for a total of 2939 and 3711 patient-years, respectively. The incidence rate of esophageal adenocarcinoma was 2.8 (95% confidence interval, 1.2-5.3) per 1000 patient-years among surgically treated patients and 6.3 (3.6-10.1) among medically treated patients (P = 0.034). Heterogeneity in incidence rates in surgically treated patients was observed between controlled studies and case series (P = 0.014). Among controlled studies, incidence rates were 4.8 (1.7-11.1) and 6.5 (2.6-13.8) per 1000 patient-years in surgical and medical patients, respectively (P = 0.320). Probability of progression was 2.9% (1.2-5.5) in surgical patients and 6.8% (2.6-12.1) in medical patients (P = 0.054). Probability of regression was 15.4% (6.1-31.4) in surgical patients and 1.9% (0.4-7.3) in medical patients (P = 0.004). CONCLUSIONS Antireflux surgery is associated with regression of Barrett esophagus and/or dysplasia. However, evidence suggesting that surgery reduces the incidence of adenocarcinoma is largely driven by uncontrolled studies.

Abstract
This study reviews current data regarding duodenogastric and gastroesophageal bile reflux-pathophysiology, clinical presentation, methods of diagnosis (namely, 24-hour intraluminal bile monitoring) and therapeutic management. Duodenogastric reflux (DGR) consists of retrograde passage of alkaline duodenal contents into the stomach; it may occur due to antroduodenal motility disorder (primary DGR) or may arise following surgical alteration of gastoduodenal anatomy or because of biliary pathology (secondary DGR). Pathologic DGR may generate symptoms of epigastric pain, nausea, and bilious vomiting. In patients with concomitant gastroesophageal reflux, the backwash of duodenal content into the lower esophagus can cause mixed (alkaline and acid) reflux esophagitis, and lead, in turn, to esophageal mucosal damage such as Barrett's metaplasia and adenocarcinoma. The treatment of DGR is difficult, non-specific, and relatively ineffective in controlling symptoms. Proton pump inhibitors decrease the upstream effects of DGR on the esophagus by decreasing the volume of secretions; promotility agents diminish gastric exposure to duodenal secretions by improving gastric emptying. In patients with severe reflux resistant to medical therapy, a duodenal diversion operation such as the duodenal switch procedure may be indicated.

Abstract
INTRODUCTION Laparoscopic esophagomyotomy is the preferred approach to patients with achalasia of the esophagus, However, there are very few long-term follow-up studies (>10 years) in these patients. OBJECTIVE To perform a very late subjective and objective follow-up in a group of 67 patients submitted to esophagomyotomy plus a partial antireflux surgery (Dor's technique). MATERIAL AND METHODS In a prospective study that lasted 30 years, 67 patients submitted to surgery were divided into 3 groups: group I followed for 80 to 119 months (15 patients); group II, with follow-up of 120 to 239 months (35 patients); and group III, with follow-up more than 240 months (17 patients). They were submitted to clinical questionnaire, endoscopic evaluation, histologic analysis, radiologic studies, manometric determinations, and 24-hour pH studies late after surgery. RESULTS Three patients developed a squamous cell esophageal carcinoma 5, 7, and 15 years after surgery. At the late follow-up, Visick III and IV were seen in 7%, 23%, and 35%, according to the length of follow-up of each group. Endoscopic examination revealed a progressive nonsignificant deterioration of esophageal mucosa, histologic analysis distal to squamous-columnar junction showed a significant decrease of fundic mucosa in patients of group III, with increase of intestinal metaplasia, although not significant time. Lower esophageal sphincter showed a significant decrease of resting pressure 1 year after surgery, which remained similar at the late control. There was no return to peristaltic activity. Acid reflux measured by 24-hour pH studies revealed a progressive increase, and the follow-up was longer. Nine patients developed Barrett esophagus: 6 of them a short-segment and 3 a long-segment Barrett esophagus. Final clinical results in all 67 patients demonstrated excellent or good results in 73% of the cases, development of epidermoid carcinoma in 4.5%, and failures in 22.4% of the patients, mainly due to reflux esophagitis. Incomplete myotomy was seen in only 1 case. CONCLUSION In patients with achalasia submitted to esophagomyotomy and Dor's antireflux procedure, there is a progressive clinical deterioration of initially good results if a very long follow-up is performed (23 years after surgery), mainly due to an increase in pathologic acid reflux disease and the development of short- or long-segment Barrett esophagus.

Abstract
BACKGROUND Regression of intestinal metaplasia to cardiac mucosa in patients with Barrett's (BE) esophagus could alter the natural history of BE. OBJECTIVE To determine the regression of intestinal metaplasia to cardiac mucosa in patients followed more than 5 years after operation, by repeated endoscopy with biopsy. MATERIAL AND METHODS This prospective study included 78 patients with BE submitted to combined vagotomy, antrectomy (an antireflux procedure), and Roux-en-Y gastrointestinal reconstruction with more than 60 months follow up. Patients were divided in 3 groups: (1) 31 with short-segment BE (< or =30 mm length); (2) 42 with long-segment BE (31 to 99 mm length); and (3) 5 with extra-long-segment BE (> or =100 mm). Each patient had at least three endoscopic procedures with multiple biopsies during a mean follow up of 95 months (range, 60-220 months). Acid and duodenal reflux were also evaluated. RESULTS Sixty-four percent of patients with short segment BE had regression to cardiac mucosa at a mean of 40 months after operation. Sixty-two percent of patients with long segment BE had regression to cardiac mucosa at a mean of 47 months postoperatively. No regression occurred in the 5 patients with extra-long segment BE. In 20% of patients, regression to fundic mucosa occurred between 78 to 94 months after surgery. One patient progressed to low grade dysplasia, but no patient progressed to high-grade dysplasia or adenocarcinoma. Acid and duodenal reflux studies demonstrated that in asymptomatic patients, reflux was abolished; 90% of the patients had a Visick grade of 1 or 2. CONCLUSIONS Vagotomy and antrectomy combined with duodenal bile diversion abolish acid and duodenal reflux into the distal esophagus in patients with BE, which is accompanied by a regression of BE from intestinal to cardiac or fundic mucosa in about 60% of patients. This regression is time dependent and varies directly with the length of BE. The potential for an antineoplastic effect, especially in young patients with long segment BE, suggests that this operation may become an attractive option as a definitive surgical treatment. Patients with short segment BE submitted to this procedure behave similar to patients submitted to Nissen fundoplication, and therefore in these patients, we do not advocate this complex operation.

Abstract
The most significant precancerosis in the esophageal cancer is Barrett's esophagus. The risk of malignant transformation is determined primarily in accordance with the degree of dysplastic alterations of the mucosa. Indication of "preventive" extirpation of the esophagus should be supported by other factors, for example by detection of p53 mutation or expression. The study reports on the evaluation of a group of 20 patients with Barrett's esophagus treated at the 1st Department of Surgery, the p53 level and its correlation with histological findings evaluated in these patients. A good correlation was found between the grade of Barrett's esophagus dysplasia and high p53 positivity. This correlation was also confirmed by detection of early carcinoma in patients with "preventive" extirpation of the esophagus due to a high-grade dysplasia. Preliminary results show that examination of p53 level in specimens taken from the esophageal mucosa may be helpful for the estimation of malignant potential of the dysplastic mucosa.

Abstract
OBJECTIVE To determine whether the elimination of bile reflux in the established esophagojejunostomy model of Barrett's esophagus (BE) will reduce or eliminate the risk of developing esophageal adenocarcinoma. SUMMARY BACKGROUND DATA Reflux of duodenal juice as well as gastric acid plays an important role in the pathogenesis of BE and adenocarcinoma. Duodenoesophageal reflux (DER) per se induces these diseases without carcinogen. However, it is unclear whether antireflux surgery induces regression of BE and prevents adenocarcinoma. METHODS Two hundred F344 male rats underwent one of following 3 operations: (1) total gastrectomy and esophagojejunostomy to induce DER, followed by killing after 20 (n = 13), 30 (n = 12), and 50 weeks (n = 30); (2) biliary diversion procedure, converted to Roux-en-Y method, to avoid bile regurgitation into the esophagus at 20 (n = 29) and 30 weeks (n = 32) after the operation to induce DER, followed by killing 50 weeks after initial operation; or (3) total gastrectomy and Roux-en-Y esophagojejunostomy followed by killing after 50 weeks served as controls (n = 28). RESULTS BE developed in more than half of the animals exposed to DER for 20 weeks, in more than 90% of rats with DER for 30 weeks, and in 100% of animals exposed to DER for 50 weeks. In the incidence and the length of BE, there is no difference between the animals that underwent biliary diversion at 20 (62%) and 30 weeks (94%) and those that had DER for 20 (54%) and 30 weeks (92%), respectively. Incidence of adenocarcinoma was significantly lower in the rats that underwent the biliary diversion procedure after 30 (19%) and 20 weeks (3%) than in the rats that had DER for 50 weeks (60%) (P < 0.005). None of the control animals that underwent Roux-en-Y esophagojejunostomy developed BE and carcinoma. CONCLUSIONS It is likely that the converting procedure from the esophagojejunostomy to induce DER to biliary diversion does not lead to regression of BE but prevents the development of esophageal adenocarcinoma in the rats.

Abstract
Barrett's esophagus is a complication of long-standing gastroesophageal reflux and can be a premalignant condition. The goals of surgical treatment, which were well summarized by DeMeester, have been increased and more detailed by us. They consist of (1) controlling symptoms of gastroesophageal reflux disease; (2) abolishing acid and duodenal reflux into the esophagus; (3) preventing or eliminating the development of complications; (4) preventing extension of or an increase in the length of intestinal metaplasia; (5) inducing regression of intestinal metaplasia to the cardiac mucosa; and (6) preventing progression to dysplasia, thereby inducing regression of low-grade dysplasia and avoiding the appearance of an adenocarcinoma. We have reviewed 25 articles in the English-language literature published from 1980 to 2003 dealing specifically with the surgical treatment of Barrett's esophagus. In most of these papers too few patients were included, the follow-up was less than 60 months, and the clinical success deteriorated with time. Acid reflux persists after surgery in nearly 35% of Barrett's esophagus patients; and at 10 years after surgery duodenal reflux is present in 95%. Peptic ulcer, stricture, and erosive esophagitis are present in 15% to 30% late after surgery, and in 16% there is progression of the intestinal metaplasia. There is the appearance of low-grade dysplasia in 6.0% and adenocarcinoma in 3.4%, and there is regression of low-grade dysplasia in 45.0%. These results challenge the arguments supporting antireflux surgery for patients with Barrett's esophagus: The clinical results are not optimal, no long-lasting effect has been demonstrated, and it does not prevent the appearance of dysplasia or adenocarcinoma. An excellent alternative is acid suppression and a duodenal diversion procedure, which has had 91% clinical success for more than 5 years. This regimen has almost eliminated acid and duodenal reflux, and there has been no progression to dysplasia or adenocarcinoma. Moreover, in 60% of the patients with low-grade dysplasia, regression to nondysplastic mucosa has occurred.

Abstract
Bile reflux gastritis has been recognized since the first successful gastric operations and has persisted for more than a century. Diagnosis has been difficult and non-operative therapy largely ineffective. Early attempts at surgical correction resulted in stomal ulceration and it was not until the advent of flexible endoscopy and other techniques that diagnosis became more secure. Operative attempts at correction have included the Roux-en-Y procedure, the Braun enteroenterostomy, and Henley jejunal interposition. None of the procedures has been uniformly successful, and the Roux-en-Y has resulted in a disabling stasis syndrome in most patients. The diagnosis of bile reflux without previous gastric surgery has been even more elusive and seems to be associated with previous cholecystectomy. Thirty-one patients diagnosed with primary bile reflux, having typical symptoms of epigastric pain, nausea, and bilious vomiting have been treated by diverting bile flow through a Roux-en-Y choledochojejunostomy without accompanying gastric resection or vagotomy. There were no operative deaths and no long-term problems, such as anastomotic stricture. Two patients had self-limited bile leaks. Twenty-seven of the 31 patients (87%) have achieved complete relief of symptoms and have no gastrointestinal complaints. Serial gastric emptying has demonstrated no alteration in 9 of 12 patients who were normal before operation, and improvement in 12 of the 19 (63%) patients with abnormal preoperative studies.

Abstract
Barrett's oesophagus is usually the result of severe reflux disease. Relief of reflux symptoms is the primary aim of treatment in patients with Barrett's oesophagus who do not have high-grade dysplasia. Some studies with medium-term (2-5 years) follow up show that antireflux surgery can provide good or excellent symptom control, with normal oesophageal acid exposure, in more than 90% of patients with Barrett's oesophagus. Antireflux surgery, but not medical therapy, can also reduce duodenal nonacid reflux to normal levels. There is no conclusive evidence that antireflux surgery can prevent the development of dysplasia or cancer, or that it can reliably induce regression of dysplasia, and patients with Barrett's oesophagus should therefore remain in a surveillance programme after operation. Some data suggest that antireflux surgery can prevent the development of intestinal metaplasia (IM) in patients with reflux disease but no IM. The combination of antireflux surgery plus an endoscopic ablation procedure is a promising treatment for patients with Barrett's oesophagus with low-grade dysplasia.

Abstract
OBJECTIVE To assess whether the presence of Barrett's esophagus (BE) modifies the results of Nissen fundoplication. SUMMARY BACKGROUND DATA Some authors consider that BE, whether or not there is associated stricture, significantly increases the failure rate of standard antireflux surgery; they recommend using different and more aggressive surgical procedures in all patients with BE. METHODS One hundred seventy-seven patients with gastroesophageal reflux disease, without esophageal stricture, were included in a retrospective study. Patients were divided into two groups: those with BE (n = 57) and those without BE (n = 120). Nissen fundoplication was performed in all patients by the same surgical team. Clinical, endoscopic, and functional (manometry and 24-hour pH monitoring) results in the two study groups were compared. RESULTS After a median follow-up of 5 years (range 1-18) in the BE group and 6 years (range 1-18) in the non-BE group, the rate of clinical recurrence was 8% in the BE group and 10% in the non-BE group, with no statistically significant difference. The rate of pH-metric recurrence was the same in both groups (15%). CONCLUSIONS The presence of BE without esophageal stricture does not increase the rate of failure of Nissen fundoplication.

Abstract
In the present paper optical fibre sensors for the detection of foregut diseases are described, in particular, sensors for the detection of bile, carbon dioxide and pH. Bile-containing refluxes are measured by means of a sensor which uses bilirubin as natural marker. The sensor, which is already present on the market, has been clinically validated by various hospitals. The clinically relevant parameter is the exposure time of the stomach/oesophagus mucosa to the bile. When measured in the oesophagus, it has been shown to be closely correlated with the onset of Barrett's oesophagus or general oesophagitis. Recently, optical fibres have been proposed for the continuous monitoring of carbon dioxide in the stomach: an important parameter in critically ill patients. A clinically validated prototype has shown its superiority in comparison with the traditional method, that is based on gastric tonometry. For the sake of completeness, also gastric pH sensors are considered, although at the moment their development is stationary at the laboratory stage.

Abstract
The incidence of adenocarcinoma of the esophagus has increased dramatically over recent years. Because Barrett's epithelium is recognized as a risk factor for adenocarcinoma there is an interest in reversing this metaplasia. A number of endoscopic methods of destruction of esophageal columnar epithelium have been described. The purpose of this article is to review the currently available methods of managing Barrett's epithelium with particular reference to the role of ablative therapy in reducing the risk of adenocarcinoma.

Abstract
BACKGROUND The purpose of this study was to determine the effect of laparoscopic Roux-en-Y gastric bypass (LRYGBP) on symptomatic control of gastroesophageal reflux disease (GERD). METHODS Morbidly obese patients (n = 435) who underwent LRYGBP for morbid obesity were assessed for changes in GERD symptoms, quality of life, and patient satisfaction after surgery. RESULTS A total of 238 patients (55%) had evidence of chronic GERD, and 152 patients (64%) voluntarily participated in the study. The mean body mass index (BMI) was 48 kg/m2. The mean excess weight loss was 68.8% at 12 months. There was a significant decrease in GERD-related symptoms, including heartburn (from 87% to 22%, p<0.001); water brash (from 18% to 7%, p<0.05); wheezing (from 40% to 5%, p<0.001) laryngitis (from 17% to 7%, p<0.05); and aspiration (from 14% to 2%, p<0.01) following LRYGBP. Postoperatively, the use of medication decreased significantly both for proton pump inhibitors (from 44% to 9%, p<0.001) and for the H2 blockers (from 60% to 10%, p<0.01). SF-36 physical function scores and the mental component summary scores improved after the operation (87 vs 71; p<0.05 and 83 vs 66; p<0.05, respectively). Overall patient satisfaction was 97%. CONCLUSION LRYGBP results in very good control of GERD in morbidly obese patients with follow-up as late as 3 years. Morbidly obese patients who require surgery for GERD may be better served by LRYGBP than fundoplication because of the additional benefit of significant weight loss.

Abstract
It is well known that in patients with Barrett's esophagus (BE), even after antireflux surgery, intestinal metaplasia can progress to dysplasia or even adenocarcinoma. However, the opposite-that is regression of dysplastic changes to intestinal metaplasia after antireflux surgery-has been documented in only a few reports. The objective of this study was to determine the effect of a duodenal diversion operation on low-grade dysplasia in patients with BE. Thirty-seven patients with either short-segment (n = 12) or long-segment (n = 25) BE underwent antireflux surgery plus either a duodenal switch procedure (13 patients) or a partial distal gastrectomy with Roux-en-Y gastrojejunal anastomosis (24 patients). All of them were subjected to complete clinical, endoscopic, histologic, manometric, and 24-hour pH testing, and 24-hour monitoring of the bile exposure in distal esophagus. There were no deaths in this series, and morbidity occurred in only one patient (2.7%). Manometric assessment after surgery showed a significant increase in sphincter pressure, abdominal length, and total length (P < 0.001). Acid reflux showed a significant decrease after surgery, and duodenal reflux was completely abolished in all except one patient. Follow-up in all patients was longer than 24 months (mean 60 months). Three to four endoscopic procedures were performed after surgery in each patient, and several biopsy specimens were taken distal to the squamo-columnar junction during each endoscopic procedure. Eleven patients (91%) with short-segment BE demonstrated histologic regression to either cardiac mucosa or nondysplastic intestinal metaplasia. Among the 25 patients with long-segment BE, there was a 62.5% rate of histologic regression to nondysplastic epithelium when the length of BE measured between 31 and 99 mm and 33% histologic regression when the length of BE was 101 mm or more. There were no cases of progression to high-grade dysplasia or adenocarcinoma. The endoscopic length of the columnar-lined esophagus did not change late after surgery. In 65% of patients with BE, antireflux surgery, gastric acid reduction, and duodenal diversion produced histologic regression of low-grade dysplasia to nondysplastic mucosa. This effect was even more pronounced when the length of BE was shorter. It seems to be permanent, and no progression to high-grade dysplasia or adenocarcinoma has occurred.

Abstract
Endoscopic management options for BE with high-grade dysplasia consist of either surveillance methods or endoscopic mucosal ablative therapies. Intensive surveillance once a person is diagnosed with high-grade dysplasia may avoid an unneeded esophagectomy because it appears that most patients with high-grade dysplasia may not progress to esophageal adenocarcinoma. Only a single study has been presented that demonstrates that this approach does not lead to missed opportunities for intervention before progression to advanced stage disease [20]. This study excluded patients with cancer detected within 1 year of diagnosis of high-grade dysplasia; thus, patients who wish to proceed with an observation approach should be aware that the rate of missed esophageal adenocarcinomas ranges from 38% to 73%. The ability to observe a patient with high-grade dysplasia, however, does have appeal because a number of these patients appear to lose the high-grade dysplasia over time. The other endoscopic management option for Barrett's esophagus with high-grade dysplasia is endoscopic mucosal ablative therapies. These include the KTP:YAG laser, the Nd:YAG laser, photodynamic therapy, and endoscopic mucosal resection. All ablative therapies are used in combination with control of gastroesophageal reflux. This allows the esophageal tissue to heal in an environment that is conducive to squamous mucosa. Although most are relatively small series with short durations of observation, they all have shown some promise in treating BE with high-grade dysplasia. These approaches have the advantage of eliminating the problem. The patient who is being observed must live with the thought of developing cancer. Patients who undergo successful ablation are returned to a normal life. The combination of therapies such as EMR with PDT may be the most promising approach to BE with high-grade dysplasia; however, the long-term effects of ablative therapy are not known and continued surveillance is still advised for this group of patients. The choice of a nonsurgical approach for the management of BE with high-grade dysplasia is ultimately up to the individual patient. All patients must be carefully informed of the treatment effects, possible outcomes, and the surgical alternative. Most patients who select nonsurgical approaches are either elderly or are not good surgical candidates. The choice is often affected by local expertise, as surgical procedures should be performed in centers with surgeons expert in esophagectomy. Nonsurgical approaches should also be performed by physicians who are familiar with their application. Future advances in nonsurgical techniques such as new photosensitizers in PDT and improvements in diagnostic techniques may allow patients a greater opportunity to preserve their esophagus.

Abstract
With the high prevalence of gastroesophageal reflux-like symptoms in the United States and the association between GERD symptoms and the premalignant condition of BE, there is more and more demand for new and efficacious techniques to treat BE. A wide variety of endoscopic mucosal ablative techniques have been developed with promising initial results. Long-term control of neoplastic risk, however, has not been demonstrated, and most studies demonstrate that there is still potentially some intestinal mucosa present underneath squamous mucosa. Currently, more study is needed to determine which patient groups require therapy of any kind and to determine which therapies would be the most efficacious. Genetic markers may aid in identification of subgroups that are at risk for cancer and help to identify those who would respond to mucosal therapy. Even in patients who have HGD, subgroups of patients who have focal HGD have been found to have better prognosis than those who have more widespread HGD. Currently, there is sufficient information to consider mucosal ablative techniques in patients who are not good surgical candidates. Photodynamic therapy, APC, KTP, Nd:YAG and argon lasers, MPEC, and EMR may provide good alternatives, depending on the degree of dysplasia, the extent of disease, and the age of the patient. Photodynamic therapy and Nd:YAG laser therapy have been applied to more neoplastic lesions, whereas KTP:YAG, APC, and multipolar coagulation have been successful in nondysplastic Barrett's mucosa. In the future, there will be more information to justify the application of mucosal ablative therapy in selected patients.

Abstract
In summary, vagotomy plus antrectomy and the Roux-en-Y procedure is based on the following points: (a) patients who have BE show several foregut abnormalities, including incompetent lower esophageal sphincter, impairment in the esophageal clearance, severe gastroesophageal acid reflux, and frequent duodenoesophageal reflux; (b) late results of classic antireflux procedure in BE are poor with a high recurrence rate owing to a progressive loosening of the wrap; (c) the esophageal damage is produced by the injurious component of the refluxate; and (d) among patients who underwent classic antireflux surgery, a certain proportion developed dysplasia or even adenocarcinoma in the follow-up. The authors have observed that the simple correction of the valve is not enough in many cases, because it does not abolish the gastroesophageal reflux but only diminishes it. In patients who have BE and therefore have impaired esophageal clearance, few reflux episodes can maintain or even induce more damage. With the reduction diversion antireflux procedure, the quality of the corrected valve is secondary, and the main goal is to avoid the reflux of injurious components of the refluxate instead of the refluxate itself, which is almost always impossible. Late results support this hypothesis, and the authors propose this surgical procedure as an alternative treatment in patients who have complicated BE or in patients who have long-segment BE. Among patients who have gastroesophageal reflux and intestinal metaplasia of the cardia or with a noncomplicated short-segment BE, laparoscopic antireflux surgery is the authors' first choice, and only the late objective evaluation of surgical treatment demonstrates which surgical technique is the more adequate to a particular patient who has BE.

Abstract
Antireflux surgery, highly selective vagotomy (HSV) and Roux-en-Y duodenojejunostomy have been suggested for control of pathophysiological factors involved in patients with Barrett's esophagus (BE). The aim of this study was to evaluate prospectively the results of this technique in patients with complicated (n = 21) and noncomplicated (n=45) BE. Complete evaluation of esophageal function, endoscopic histologic and clinical control was carried out before and 2 years after surgery. Post-operative results show recurrence of ulcer in patients with complicated BE, but no recurrence in patients with non-complicated BE. Preoperative esophageal ulcer and stricture were present in 85.3% and 14.3%, respectively, of patients with complicated BE. In this group, recurrence of these complications was 38.1% and 9.5% respectively. The technique offers excellent results in patients with non-complicated BE. However, in patients with complicated BE, the recurrence rate is higher, mainly because of the persistence of acid reflux into the esophagus.

Abstract
Barrett esophagus has malignant potential and seems to be an acquired abnormality. It is associated with chronic gastroesophageal reflux disease and represents its severest form. The literature comparing medical treatment with antireflux surgery was reviewed. Questions regarding the advantages of surgery, who should undergo surgery, whether surgery can change the course of Barrett esophagus, the change in cancer risk, who needs surveillance, and cost-effectiveness were addressed. The incidence of developing Barrett cancer was 1 in 145 patient-years in reviewing 2032 patient-years of medical therapy compared with 1 in 294 patient-years in reviewing 4122 patient-years after surgery. Median follow-up time in the 2 groups was 2.7 years in the medically treated patients and 4.0 years in the surgically treated patients. Surveillance of Barrett esophagus is required irrespective of treatment. Laparoscopic antireflux surgery was found to be cost-effective after 7 years. Although these data do not prove that surgery is superior to medical treatment in the prevention of cancer related to Barrett esophagus, we found a tendency for surgery to be better than medical therapy to prevent the development and progression of Barrett carcinoma.

Abstract
OBJECTIVE To evaluate the rate of duodenogastroesophageal reflux in patients with columnar lined esophagus compared with patients with gastroesophageal reflux disease without columnar lined esophagus, and to analyze whether it is related to the presence of specialized columnar epithelium in the metaplastic segment. SUMMARY BACKGROUND DATA The carcinomatous degeneration of columnar lined esophagus originates from a specialized columnar epithelium. The appearance of this metaplastic phenomenon is clearly related to severe prolonged gastroesophageal reflux, but only some of these patients finally develop columnar lined esophagus. For this reason other factors have been suggested, particularly the role played by the reflux of duodenal contents into the esophagus. METHODS The authors studied 15 healthy volunteers (control group), 10 patients with reflux symptoms but without endoscopic lesions, 20 patients with reflux esophagitis without columnar lined esophagus, and 35 patients with columnar lined esophagus (complicated with ulcers or stenosis in 8 cases), of whom 22 had intestinal metaplasia. To assess the reflux of duodenal contents into the esophagus, all the patients underwent Bilitec 2000 and 24-hour esophageal pH monitoring. RESULTS The presence of bilirubin in the material refluxed into the esophagus was greater in the patients with columnar lined esophagus than in the rest of the groups. Likewise, duodenogastroesophageal reflux was greater in the columnar lined esophagus patients who had intestinal metaplasia. CONCLUSIONS Duodenogastroesophageal reflux may play a major role in the development of columnar lined esophagus, especially in patients with intestinal metaplasia.

Abstract
BACKGROUND Columnar-lined esophagus with intestinal metaplasia (IM), also called Barrett's esophagus, is a manifestation of severe gastroesophageal reflux (GER) and may predict poor symptom relief and high failure rate after fundoplication. We compared symptom scores and reoperation rates in GER patients with and without Barrett's esophagus. METHODS Between July 1992 and July 1997, 646 patients underwent fundoplication (626 laparoscopic). Of 150 endoscopic biopsies of suspected columnar-lined esophagus, 80 confirmed IM, 50 identified cardiac or fundic epithelium, and 20 revealed only esophagitis. Typical GER symptoms were scored by patients preoperatively and postoperatively (0 to 4 scale). We compared symptom response (Wilcoxon rank sum test) and failure rates (t test) in patients with IM and GER controls without IM. Preoperative data were available for 74 IM patients and 496 controls. One-year follow-up was available in 45 IM patients and 301 controls. Intermediate follow-up (2 to 5 years) was available in 20 IM patients and 99 controls. RESULTS Preoperatively and postoperatively, patients with IM reported heartburn, regurgitation, and dysphagia scores similar to controls. Procedure failure, requiring redo fundoplication, appeared more likely in IM patients than controls (6.3% versus 2.5%), but this difference did not reach statistical significance (P = 0.061). CONCLUSION Fundoplication provides equivalent symptom relief for patients with and without IM.
