Abstract
Hiatus hernias (HH) are a common cause of symptoms and complications, with considerable variation in anatomy, function, diagnosis and treatment. We undertook the first systematic review to appraise how HH are diagnosed and classified in the literature, using randomized controlled trials as a sample. A search was performed in July 2021of the PubMed, EMBASE and Cochrane Central Register of Controlled Trials, and 2832 articles were identified and 64 were included. Median Jadad score was 2. Studies demonstrated considerable variation in diagnosis, classification and minimum surgical steps. The commonest classifications before surgery were axial length and the Type I-IV classification, variably assessed by endoscopy and contrast swallow. Intra-operatively, the commonest classification was type I-IV. A minority used more than one classification, or alternatives such as defect size and Hill classification. Most studies reported minimum steps, but these varied. Only a minority reported criteria for diagnosing recurrence. Using randomized controlled trials to appraise the highest quality evidence in the literature, we found considerable variation and inconsistency in the way HH are diagnosed and classified. This lack of a 'common language' has significant impacts for the generalizability of evidence, study synthesis and design. We propose the development of an internationally accepted classification. We wish to confirm that there are no known conflicts of interest associated with this publication and there has been no significant financial support for this work that could have influenced its outcome. We confirm that the manuscript has been read and approved by all named authors and that there are no other persons who satisfied the criteria for authorship but are not listed. We further confirm that the order of authors listed in the manuscript has been approved by all of us.

Abstract
OBJECTIVE To determine late results of AS-DD procedure in long-segment (LSBE) and extralong-segment BE (ELSBE) using subjective and objective measurements to ascertain the histological impact over intestinal metaplasia (IM) and progression to EAC. SUMMARY OF BACKGROUND DATA Barrett esophagus (BE) is a known precursor of esophageal adenocarcinoma (EAC), and Nissen fundoplication has proven to be unable to stop mixed reflux among them. Our group proposed a surgical procedure that handles pathophysiological changes responsible for BE. METHODS This prospective study included 127 LSBE and ELSBE subjects submitted to clinical and functional analyses. They were presented to selective vagotomy, fundoplication, partial gastrectomy with Roux-en-Y reconstruction. The changes in IM were determined in both groups. RESULTS Follow-up was completed at a mean of 18 years in 81% of the cases. Visick I-II scores were seen in 88% of LSBE and 65% in ELSBE ( P < 0.01). There was significant healing of erosive esophagitis and esophageal peptic ulcers, and strictures were resolved in 71%. There was 38% of IM regression in LSBE. Two cases in each group progressed to EAC at a mean of 15 years. Pathologic acid reflux was abolished in 91% and duodenal in 100%. There was a regression of low-grade dysplasia to IM in 80%. CONCLUSIONS AS-DD permanently eliminates pathologic refluxate to the esophagus. The progression to HGD/EAC is lower compared to medical treatment, with an 8-fold reduction in LSBE and 2.2-fold in ELSBE. AS-DD seems to influence IM behaviors, and it is a tool that could reduce and delay progression to EAC.

Abstract
INTRODUCTION Laparoscopic Nissen fundoplication is the preferred operative treatment for patients with gastroesophageal reflux disease. The most recent published results only refer to clinical evaluations and few discuss objective measurements. Our purpose was to determine the late results of laparoscopic Nissen fundoplication, performing clinical, endoscopic, histologic, and functional studies. MATERIAL AND METHODS A total of 179 patients were included in a prospective study. All had gastroesophageal reflux disease symptoms of at least 5-year duration, daily dependence on proton pump inhibitors, and a type I hiatal hernia less than 5 cm. Exclusion criteria included Barrett's esophagus, hiatal hernia >5 cm, failed antireflux surgery, and obesity (body mass index >30). We performed a radiologic study, 3 or more endoscopic procedures with biopsy samples of the antrum and esophagogastric junction, esophageal manometry, and 24-hour pH monitoring. RESULTS We found that 4 patients (2.2%) died 3-4 years after operation from nonoperatiove reasons. A total of 25 patients (14%) were lost to follow-up, and 150 patients (83.8%) submitted to late objective evaluations (15 years). Visick I-II symptoms were observed in 79.3% and III-IV (failures) in 20.7%. Endoscopy showed a normal positioning of the esophagogastric junction in the Visick I-II patients and a type III cardia or hiatal hernia with erosive esophagitis in Visick III-IV patients. Short-segment Barrett's esophagus developed in 5.3% of patients. Lower esophageal sphincter pressure remained increased over the preoperative value in all groups. The 24-hour pH monitoring also was decreased over the preoperative value in Visick I-II patients but showed no significant change in Visick III-IV patients. Carditis at the esophagogastric junction regressed to fundic mucosa in 50% of Visick I-II patients. CONCLUSION Laparoscopic Nissen fundoplication produces control of symptoms in 80% of patients late (up to 15 years) after surgeries corroborated by endoscopic, histologic examinations, and functional studies. It is essential to perform these objective evaluations to demonstrate the "antireflux effect" after laparoscopic Nissen fundoplication.

Abstract
BACKGROUND Treatments for Barrett's oesophagus, the precursor lesion of adenocarcinoma, are available but whether these therapies effectively prevent the development of adenocarcinoma, and in some cases eradicate the Barrett's oesophagus segment, remains unclear. OBJECTIVES To summarise, quantify and compare the efficacy of pharmacological, surgical and endoscopic treatments for the eradication of dysplastic and non-dysplastic Barrett's oesophagus and prevention of these states from progression to adenocarcinoma. SEARCH STRATEGY We searched CENTRAL (The Cochrane Library 2004, issue 4), MEDLINE (1966 to June 2008) and EMBASE (1980 to June 2008). SELECTION CRITERIA Randomised controlled trials (RCTs) comparing medical, endoscopic or non-resectional surgical treatments for Barrett's oesophagus. The primary outcome measures were complete eradication of Barrett's and dysplasia at 12 months, and reduction in the number of patients progressing to cancer at five years or latest time point. DATA COLLECTION AND ANALYSIS Three authors independently extracted data and assessed the quality of the trials included in the analysis. MAIN RESULTS Sixteen studies, including 1074 patients, were included. The mean number of participants in the studies was small (n = 49; range 8 to 208). Most studies did not report on the primary outcomes. Medical and surgical interventions to reduce symptoms and sequelae of gastro-oesophageal reflux disease (GORD) did not induce significant eradication of Barrett's oesophagus or dysplasia. Endoscopic therapies (photodynamic therapy (PDT with aminolevulinic acid or porfimer sodium), argon plasma coagulation (APC) and radiofrequency ablation (RFA)) all induced regression of Barrett's oesophagus and dysplasia. The data for photodynamic therapy were heterogeneous with a mean eradication rate of 51% for Barrett's oesophagus and between 56% and 100% for dysplasia, depending on the treatment regimens. The variation in photodynamic therapy eradication rates for dysplasia was dependent on the drug, source and dose of light. Radiofrequency ablation resulted in eradication rates of 82% and 94% for Barrett's oesophagus and dysplasia respectively, compared to a sham treatment. Endoscopic treatments were generally well tolerated, however all were associated with some buried glands, particularly following argon plasma coagulation and photodynamic therapy, as well as photosensitivity and strictures induced by porfimer sodium based photodynamic therapy in particular. AUTHORS' CONCLUSIONS Despite their failure to eradicate Barrett's oesophagus, the role of medical and surgical interventions to reduce the troubling symptoms and sequelae of GORD is not questioned. Whether therapies for GORD reduce the cancer risk is not yet known. Ablative therapies have an increasing role in the management of dysplasia within Barrett's and current data would favour the use of radiofrequency ablation compared with photodynamic therapy. Radiofrequency ablation has been shown to yield significantly fewer complications than photodynamic therapy and is very efficacious at eradicating both dysplasia and Barrett's itself. However, long-term follow-up data are still needed before radiofrequency ablation can be used in routine clinical care without the need for very careful post-treatment surveillance. More clinical trial data and in particular randomised controlled trials are required to assess whether or not the cancer risk is reduced in routine clinical practice.

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
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
Using a Collis-Nissen repair instead of a standard Nissen fundoplication to treat the reflux disease of Barrett's esophagus is controversial. This paper compares the Nissen and Collis-Nissen operations when treating Barrett's esophagus. Thirty-three patients with documented Barrett's esophagus (male : female, 26 : 7, median age, 48.8 years) had a Nissen fundoplication during 1976-1989. Fifty-one patients (male : female = 41 : 10, median age = 53.2 years) underwent a Collis-Nissen operation between 1990 and 1999. Clinical assessments, esophagogram, radionuclide emptying, manometry, 24-h pH study, and endoscopy were obtained pre- and postoperatively. There was no operative death in either group. Median follow-up was 8.0 years for the Nissen group and 6.5 years for the Collis group. Postoperative reflux symptoms were more frequent in the Nissen group (52%) when compared to the Collis group (7%, P < 0.001). These symptoms correlated with the 24-h pH recordings revealing an increased acid exposure in the Nissen group (3.4%) as opposed to 1% in the Collis group (P = 0.003). Endoscopy revealed mucosal erosions and ulcers in 39% of patients receiving a standard Nissen repair while these damages were seen in 7% of patients who were offered an elongation gastroplasty with a total fundoplication (P = 0.007). The cumulative success rate was 83% for the Nissen group and 100% for the Collis group at 5 years, and 63% versus 90% at 10 years (Log-rank test, P = 0.004). The Collis-Nissen fundoplication provides better reflux protection for Barrett's patients than a standard Nissen repair. It lowers the risk of fundoplication failure.

Abstract
Laparoscopic antireflux surgery is the gold standard procedure for treatment of patients with reflux esophagitis. The current results of the laparoscopic approach are absolutely comparables with the results obtained during the open surgery era. The Nissen, Nissen-Rossetti, or Toupet techniques are the more frequently used. We have performed cardial calibration and posterior gastropexy or Nissen fundoplication by the open approach with similar results. The purpose of this article is to present the anatomo-physiological basis for employing cardial calibration and posterior gastropexy in patients with reflux esophagitis. This study includes 108 symptomatic patients, 12 of them with associated extraesophageal manifestations ( posterior laryngitis). Endoscopic mild or moderate esophagitis was confirmed in 83 patients, Barrett's esophagus in 12 patients, and type I or II hiatal hernia in 13 patients. All patients were also submitted to manometry, 24 hour intraesophageal pH monitoring, and barium swallow before and after surgery. Follow-up ranged from 12 to 36 months. There were no conversion, major intraoperative, or postoperative complications; nor were there any deaths. Postoperative dysphagia was present in 5% of cases. Symptomatic recurrence of reflux was observed in 10.3% and endoscopic presence of esophagitis in 12.3% of cases . Lower esophageal sphincter pressure increased significantly after surgery, even in patients with endoscopic recurrence. 24-hour intraesophageal monitoring improved after surgery, except in patients with objective recurrence of esophagitis. In conclusion, laparoscopic cardial calibration with posterior gastropexy presents comparable results to those reported after Nissen fundoplication and therefore could be another excellent therapeutic option in patients with reflux esophagitis.

Abstract
Given the anatomic and functional defects almost universally present in patients who have BE, antireflux surgery is the most reliable means of stopping acid and nonacid (alkaline) reflux. Because patients who have BE have end-stage GERD, they require durable and reliable control of reflux, and the Hill procedure and partial fundoplication are associated with unacceptably high failure rates. In addition, there is mounting evidence that the success rates for Nissen fundoplication are lower in patients who have BE than in patients who have less severe GERD. Given that the most common mode of failure of a laparoscopic Nissen fundoplication is herniation of the fundoplication into the chest, patients who have BE must be considered at risk for having a short esophagus. The failure rate may be reduced by the liberal addition of a Collis gastroplasty, but the long-term consequences of acid-secreting mucosa left above the fundoplication in patients who have BE remain unclear. Patients suspected of having a short esophagus on the basis of a large hiatal hernia, stricture, or long-segment BE should be considered for a transthoracic approach to their fundoplication, as this affords good esophageal mobilization and may obviate the need for a gastroplasty. Surgeons must pay particular attention to their own and published results and continue to refine the operation to maximize the likelihood of a good outcome in this difficult group of patients. It is only with excellent control of reflux that any differences in the risk of progression to dysplasia and cancer become apparent, and significant, between medically and surgically treated patients.

Abstract
Gastroesophageal reflux disease (GERD) is a common health problem affecting more than 50% of the population. For those who experience more than occasional symptoms, GERD has a profound effect on their quality of life. With the advent of laparoscopic surgery, fundoplication has been used to treat GERD. Fundoplication also is used in the surgical management of paraesophageal hernias. Technical controversies are addressed in this article, including open versus laparoscopic approaches, the choice of complete (360 degres) or partial fundoplication, whether or not a gastroplasty is required, and the use of prosthetic materials in crural repair.

Abstract
There are many reports concerning the surgical treatment of patients with Barrett's esophagus, but very few focus on histological changes of inflammatory cells in squamous and columnar epithelium before and late after classic antireflux or acid suppression-duodenal diversion surgery. We evaluate the impact of these procedures in the presence of intestinal metaplasia, dysplasia and Helicobacter pylori in the columnar epithelium. Two groups of patients were studied, 37 subjected to classic antireflux and 96 to acid suppression-duodenal diversion operations. They were subjected to endoscopic and histological studies before and at 1, 3 and more than 5 years after surgery. Manometric evaluations and 24 h pH monitoring were performed before and at 1 year after surgery. The presence of inflammatory cells at both the squamous and columnar epithelium was significantly higher at the late follow up in patients subjected to classic antireflux surgery compared with patients subjected to acid suppression-duodenal diversion operations (P < 0.02 and P < 0.001, respectively). Intestinal metaplasia, present in 100% of patients before surgery, had decreased significantly at 3 years after surgery in patients subjected to acid suppression-duodenal diversion operations compared with classic antireflux procedures, 75% versus 53%, respectively (P < 0.001). The presence of Helicobacter pylori did not vary before or after surgery in either group. In conclusion, acid suppression-duodenal diversion operations are followed by a decreased presence of inflammatory cells in both squamous and columnar epithelium compared with classic antireflux surgery in patients with Barrett's esophagus. Intestinal metaplasia and dysplasia and inflammation findings were also less common after acid suppression-duodenal diversion operation.

Abstract
BACKGROUND & AIMS The diagnosis and management of Barrett's esophagus (BE) are controversial. We conducted a critical review of the literature in BE to provide guidance on clinically relevant issues. METHODS A multidisciplinary group of 18 participants evaluated the strength and the grade of evidence for 42 statements pertaining to the diagnosis, screening, surveillance, and treatment of BE. Each member anonymously voted to accept or reject statements based on the strength of evidence and his own expert opinion. RESULTS There was strong consensus on most statements for acceptance or rejection. Members rejected statements that screening for BE has been shown to improve mortality from adenocarcinoma or to be cost-effective. Contrary to published clinical guidelines, they did not feel that screening should be recommended for adults over age 50, regardless of age or duration of heartburn. Members were divided on whether surveillance prolongs survival, although the majority agreed that it detects curable neoplasia and can be cost-effective in selected patients. The majority did not feel that acid-reduction therapy reduces the risk of esophageal adenocarcinoma but did agree that nonsteroidal antiinflammatory drugs are associated with a cancer risk reduction and are of promising (but unproven) value. Participants rejected the notion that mucosal ablation with acid suppression prevents adenocarcinoma in BE but agreed that this may be an appropriate strategy in a subgroup of patients with high-grade dysplasia. CONCLUSIONS Based on this review of BE, the opinions of workshop members on issues pertaining to screening and surveillance are at variance with published clinical guidelines.

Abstract
OBJECTIVE To highlight the current available evidence in antireflux surgery through a systematic review of randomized controlled trials (RCTs). SUMMARY BACKGROUND DATA Laparoscopic fundoplication is currently suggested as the gold standard for the surgical treatment of gastroesophageal reflux disease, but many controversies are still open concerning the influence of some technical details on its results. METHODS Papers related to RCTs identified via a systematic literature search were evaluated according to standard criteria. Data regarding the patient sample, study methods, and outcomes were abstracted and summarized across studies. Defined outcomes were examined for 41 papers published from 1974 to 2002 related to 25 RCTs. A meta-analysis was performed pooling the results as odds ratios (OR), rate differences (RD), and number needed to treat (NNT). Data given as mean and/or median values were pooled as a mean +/- SD (SD). RESULTS No perioperative deaths were found in any of the RCTs. Immediate results showed a significantly lower operative morbidity rate (10.3% versus 26.7%, OR 0.33, RD -12%, NNT 8), shorter postoperative stay (3.1 versus 5.2 days, P = 0.03), and shorter sick leave (20.1 versus 35.8 days, P = 0.03) for laparoscopic versus open fundoplication. No significant differences were found regarding the incidence of recurrence, dysphagia, bloating, and reoperation for failure at midterm follow-up. No significant differences in operative morbidity (13.1% versus 9.4%) and in operative time (90.2 versus 84.2 minutes) were found in partial versus total fundoplication. A significantly lower incidence of reoperation for failure (1.6% versus 9.6%, OR 0.21, RD -7%, NNT 14) was found after partial fundoplication, with no significant differences regarding the incidence of recurrence and/or dysphagia. Routine division of short gastric vessels during total fundoplication showed no significant advantages regarding the incidence of postoperative dysphagia and recurrence when compared with no division. The use of ultrasonic scalpel compared with clips or bipolar cautery for the division of short gastric vessels showed no significant effect on operative time, postoperative complications, and costs. CONCLUSIONS Laparoscopic antireflux surgery is at least as safe and as effective as its open counterpart, with reduced morbidity, shortened postoperative stay, and sick leave. Partial fundoplication significantly reduces the risk of reoperations for failure over total fundoplication. Routine versus no division of short gastric vessels showed no significant advantages. A word of caution is needed when implementing these results derived from RCTs performed in specialized centers into everyday clinical practice, where experience and skills may be suboptimal.

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
The management of chronic gastroesophageal reflux disease (GERD) has both been simplified and immensely improved by the development of modern medical therapies. These are built entirely on the concept of profound acid inhibition, which is very successful in a substantial proportion of GERD patients. Despite the efficacy of proton pump inhibitors (PPIs) some failures are unavoidable, and some patients experience incomplete control of major GERD symptoms on ordinary dosing of PPIs. Although the safety profile of PPIs is very reassuring, some people express some concern about the safety of drug treatment extending beyond 10 years especially when alternative therapeutic strategies are available. Some patients complain of alleged respiratory complications to severe reflux, and in those situations as well as in cases with e.g. Barrett's esophagus, a complete control of reflux also incorporating the duodenal components in the refluxate may be warranted. In all those situations antireflux surgery can be considered indicated for the treatment of chronic GERD and thus be looked upon as complementary to medical therapy. Furthermore, some patients who have their GERD symptoms under control on PPIs still want to have an operation to avoid dependency on drugs. Hence in none of these clinical situations does antireflux surgery play a competitive role in relation to medical therapy. However, in the very few randomized clinical trials in which a head-to-head comparison has been completed between medical and surgical therapy, the latter has been found to be somewhat more effective in terms of reflux control. The other side of the coin is that antireflux surgery has some side effects that signify the importance of this surgery being performed in specialized centers.

Abstract
The two main aspects relevant to the role of surgery in the management of patients with Barrett's esophagus are to define the role of surgery in controlling reflux and associated symptoms and to define the surgical options in case of dysplasia or early neoplasia. This article also will address the issue of whether complete reflux control in patients with Barrett's esophagus can prevent the metaplastic mucosa from further progression to dysplasia and adenocarcinoma.

Abstract
The rate of recurrence of reflux esophagitis after classic antireflux surgery (fundoplication) is 10-15%. This rate is different in patients with esophagitis with and without Barrett's esophagus. We evaluated the clinical and laboratory findings in 104 patients with postoperative recurrent reflux esophagitis, determining the results of repeat antireflux surgery or an acid suppression-bile diversion procedure. Repeat fundoplication was performed in 26 patients, and truncal vagotomy, antrectomy, and Roux-en-Y gastrojejunostomy in 78 patients. Esophagectomy as a third operation was performed in seven patients. After repeat antireflux surgery, endoscopic evaluation demonstrated improvement of esophagitis in a small proportion of patients. Barrett's esophagus remained unchanged, and no regression of ulcer or stricture was observed. These complications improved significantly after acid suppression-bile diversion surgery. Incompetent lower esophageal sphincter (LES) was present in 55.8% after initial surgery and in 23% after reoperation. Acid reflux, initially present in 94.6% of patients, was also observed in 93.6% after fundoplication, 68.8% after redo fundoplication, and 16.6% after treatment with the acid suppression-bile diversion technique. A positive Bilitec test was present in 78% of patients before the operation and 56.6% after the repeat operation, and was negative after bile diversion surgery. Among 13 patients (50%) submitted to repeat surgery alone, esophagectomy as a third operation was necessary as a result of severe non-dilatable stricture in seven patients. Our conclusions are that repeat antireflux surgery alone failed to improve Barrett's esophagus complications and that the best results were obtained in patients submitted to acid suppression-bile diversion surgery.

Abstract
BACKGROUND It is a current opinion among surgeons that the esophagus is shorter in patients with reflux disease and particularly in those with complicated Barrett's esophagus. However, objective evidence of this is scarce. Therefore we attempted to determine the occurrence and magnitude of this phenomenon among our patients. METHODS One hundred ninety control subjects, 77 patients with severe erosive esophagitis, 74 with Barrett's esophagus, and 29 with complicated Barrett's esophagus (ulcer, stenosis) were grouped according to height. The length of the esophagus was determined by standard manometric study, measuring the distance from the crycopharingeal sphincter to the distal limit of the lower esophageal sphincter. Values were expressed in cm as the mean +/- SD. RESULTS The esophageal length according to height was 1 to 2 cm shorter in patients compared to controls, but these differences were not significant. CONCLUSIONS No differences were found between patients with progressive severity of the disease. This study confirms that the presence of a so-called "short esophagus" does not exist or is not relevant in our patients with gastroesophageal reflux disease, including those with complicated Barrett's esophagus.

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
There are controversies regarding existence and incidence of short esophagus. The authors reviewed the literature incidence of short esophagus among operated patients due to gastroesophageal reflux disease in the last 3 years. The overall incidence of short esophagus was 1.53%. The proposed risk factors (paraesophageal hernia, Barrett's esophagus, reoperation, esophageal strictures and access route) do have a higher incidence of short esophagus, with the exception of the Barrett's esophagus. Although several biases can be associated with the review, the authors identified the short esophagus incidence in the literature.

Abstract
The usual surgical treatment for patients with Barrett's esophagus (BE) is a classic Nissen fundoplication or posterior gastropexy with cardial calibration. However, some surgical reports as well as our experience suggest that the rate of failure of the Nissen fundoplication or Hill's posterior gastropexy in patients with BE is significantly higher than in those with reflux esophagitis without BE, probably due in part to the persistence of duodenal reflux into the esophagus. Our aim was to determine the late subjective and objective results of an operation consisting in "acid suppression" (vagotomy-partial gastrectomy) and "duodenal diversion" (Roux-en-Y anastomosis) as a primary surgical procedure for patients with BE. Altogether, 210 patients were subjected to this technique. It consisted in a primary operation in 142 patients and revision surgery in 68. They underwent complete clinical, radiologic, endoscopic, histologic, and manometric studies. In some cases 24-hour pH studies, Bilitec studies, gastric emptying, and gastric acid secretion evaluations were performed. There were two deaths (0.95%), and postoperative morbidity was low (5.3%). The late mean follow-up (58 months) for 146 patients who completed a follow-up longer than 24 months showed Visick I and II grades in 91.1% of the cases. In 14.9% of the cases 24-hour pH monitoring showed excessive acid reflux 1 year after surgery. No dysplasia or adenocarcinoma has appeared up to now. Functional studies showed significant alleviation of lower esophageal sphincter (LES) incompetence, with abolition of duodenal reflux into the esophagus. Gastric emptying of solids was normal, and basal and peak gastric acid output remained at a low level 8 to 10 years after surgery. In patients with BE, with severe damage of the LES and esophageal peristalsis, the "suppression diversion" operation completely abolishes the reflux of injurious components of the refluxate and improves sphincter competence. This effect is permanent and avoids the appearance of dysplasia or adenocarcinoma.

Abstract
Several therapeutic options exist for patients who have BE, and treatment should be individualized (Fig. 1). The best option in patients who have a high surgical risk or who reject surgery is lifelong conservative treatment, adjusting the PPI dosage with pH-metric controls. In patients who have a low surgical risk the best option is Nissen fundoplication. Only in cases in which esophageal shortening prevents a tension-free fundoplication from being done is a Collis gastroplasty associated with a fundoplication indicated. Other options may be indicated only in exceptional circumstances: (a) duodenal switch, when, after multiple failures with previous surgery, the approach to the esophagogastric junction is extremely difficult; and (b) esophageal resection, when there is a nondilatable esophageal stenosis and in cases in which the histologic study reveals the presence of high-grade dysplasia. Whatever treatment is used, an endoscopic surveillance program is mandatory, since, with the exception of total esophagectomy, no therapeutic option completely eliminates the risk for progression to adenocarcinoma.

Abstract
Barrett's esophagus is an end-stage gastroesophageal reflux complication with a potential for malignant transformation. This condition probably is involved in esophageal cancer being perceived today as the most rapidly increasing cancer in Western countries. Numerous observations suggest that standard antireflux operations fail over time because of long-term inflammatory and fibrotic changes in the esophageal wall that cause shortening of the esophagus. The addition of esophageal elongation by gastroplasty provides a reliable repair by creation of a tension-free repair, whereas the durable antireflux effects are provided by the total fundoplication around the neoesophagus. The restored LES tone further helps control the mucosal damage and the chronic inflammatory changes. Complete regression of the abnormal mucosa still does not occur, and persistent irritation of that mucosa still entails the risk for progression toward dysplasia. The natural history of the columnar-lined mucosa in BE may be altered by medical or surgical intervention. It is too early to judge in which settings these interventions will be meaningful.

Abstract
In most patients who have Barrett's esophagus and who are undergoing open or laparoscopic antireflux surgery, there is a significant improvement in symptom control that is equivalent to that in patients who have uncomplicated gastroesophageal reflux disease. The requirement for reoperation in patients with Barrett's esophagus may be slightly higher, although in the two laparoscopic series published to date, the rate is still only approximately 6%. How much this will increase with longer follow-up, time alone will tell, but given the good results in approximately 95% of patients operated to date, the authors do not believe that the diagnosis of Barrett's esophagus should be considered a blanket contraindication for laparoscopic antireflux surgery. Clearly, in most patients with Barrett's esophagus, an antireflux operation will not result in regression of Barrett's mucosa. It is still unclear whether antireflux surgery provides any protection against subsequent development of esophageal adenocarcinoma. What is clear, however, is that after antireflux surgery, patients who have Barrett's esophagus are still at risk for developing adenocarcinoma and should remain in surveillance programs. The authors believe that laparoscopic antireflux surgery is a safe and effective approach for the cure of reflux-related symptoms in patients who have Barrett's esophagus.

Abstract
OBJECTIVE To assess the clinical, endoscopic, and functional results in a group of patients with Barrett's esophagus undergoing classic antireflux surgery in whom dysplasia and adenocarcinoma were found at a late objective follow-up. SUMMARY BACKGROUND DATA There have been isolated reports of patients with Barrett's esophagus undergoing antireflux surgery who show dysplasia or even adenocarcinoma on follow-up. METHODS Of 161 patients undergoing surgery, dysplasia developed in 17 (10.5%) at late follow-up and adenocarcinoma developed in 4 (2.5%). These 21 patients represent the group assessed and were compared with 126 surgical patients with long-segment Barrett's in whom dysplasia did not develop. They were evaluated by clinical questionnaire, multiple endoscopic procedures and biopsy specimens, 24-hour pH studies, and 24-hour bilirubin monitoring. RESULTS Of the 17 patients with dysplasia, 3 were asymptomatic at the time that dysplastic changes appeared; all patients with adenocarcinoma had symptoms. Two patients (12%) in the dysplasia group had short-segment Barrett's; all patients with adenocarcinoma had long-segment Barrett's. Manometric studies revealed an incompetent lower esophageal sphincter in 70% of the dysplasia group, similar to nondysplasia patients with recurrence, and in 100% of the adenocarcinoma group. The 24-hour pH study showed pathologic acid reflux in 94% of the patients with dysplasia, similar to patients with recurrence without dysplasia, whereas bilirubin monitoring showed duodenal abnormal reflux in 86% of the patients. Among patients with dysplasia, three different histologic patterns were identified. All patients with adenocarcinoma had initially intestinal metaplasia, with appearance of this tumor 6 to 8 years after surgery. CONCLUSIONS Patients with Barrett's esophagus who undergo antireflux surgery need close and long-term endoscopic and histologic surveillance because dysplasia or even adenocarcinoma can appear at late follow-up. Metaplastic changes from fundic to cardiac mucosa and then to intestinal metaplasia and later to dysplasia or adenocarcinoma can clearly be documented. There were no significant differences in terms of clinical, endoscopic, manometric, 24-hour pH, and bilirubin monitoring studies between patients with recurrence of symptoms without dysplastic changes, and patients with dysplasia. Therefore, the high-risk group for the development of dysplasia is mainly the group with failed antireflux surgery.

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
Pathological gastroesophageal reflux is common. The aim of this review was to compare the results of different surgical techniques. Papers were selected on Medline from 1990 to April 2001. A critical analysis was performed, concerning definitions of included patients, surgical techniques, and criteria of evaluation. For comparison, the results of 23 randomized studies were mainly selected. Their heterogeneity has not allowed a meta-analysis. A few techniques had poorer results than others: simple closure of His angle, Hill operation, Belsey Mark IV technique, and Angelchik prosthesis. In most studies, results of partial fundoplication on reflux were as good as those of total Nissen fundoplication and fewer patients had postoperative dysphagia. In a double blind trial, immediate advantages of laparoscopic approach were less important than those observed in non comparative studies. Another trial was interrupted after inclusion of 103 patients because of the higher rate of side-effects in the laparoscopic group. These results may help the surgeon in the choice of a technique. Patients have to be informed of potential adverse effects of the different techniques chosen by their surgeon.
