Impact of laparoscopic Nissen’s fundoplication on response of disease specific symptoms and quality of life

The aim of this study is to establish responsiveness of gastroesophageal reflux disease (GERD) symptom score, quality of life SF-36 score in GERD with relation to oesophageal manometry and upper gastrointestinal endoscopy following laparoscopic Nissen’s fundoplication (LNF). Interventional prospective study was done enrolling 77 patients of GERD who respond to proton pump inhibitor (PPI) and have undergone LNF, strict diagnostic criteria were followed with GERD score, upper gastrointestinal endoscopy, oesophageal manometry, and endoscopically negative patients have further undergone 24-h pH study. Follow-up was done at 12 and 24 months by GERD score, SF-36 score, endoscopy, oesophageal manometry. GERD score shows significant difference in pre-operative and post-operative score with P value <0.001 except dysphagia. Post-LNF improvement in GERD score is consistent with improvement in lower oesophageal sphincter (LES) pressure at 12 months. All dimensions in quality of life SF-36 show significant difference in pre-operative and post-operative score at 12 months with P value <0.001. Results are consistent at 24 months. Oesophagitis was decreased from 40.2 to 11.6 % as well as it showed down grading on endoscopy in post-operative period. Out of three patients of complete disruption of wrap, two patients underwent redo surgery and showed improvement. In properly diagnosed PPI respondent patients by GERD score, LNF has got improvement in GERD score, quality of life in all dimensions of SF-36 score in relation to improvement with LES pressure and oesophagitis.     

Paradigm shift in the management of gastroesophageal reflux disease

OBJECTIVE: To compare the short-term results of the radiofrequency treatment of the gastroesophageal junction known as the Stretta procedure versus laparoscopic fundoplication (LF) in patients with gastroesophageal reflux disease (GERD). SUMMARY BACKGROUND DATA: The Stretta procedure has been shown to be safe, well tolerated, and highly effective in the treatment of GERD. METHODS: All patients presenting to Vanderbilt University Medical Center for surgical evaluation of GERD between August 2000 and March 2002 were prospectively evaluated under an IRB-approved protocol. All patients underwent esophageal motility testing and endoscopy that documented GERD preoperatively, either by a positive 24-hour pH study or biopsy-proven esophagitis. Patients were offered the Stretta procedure if they had documented GERD and did not have a hiatal hernia larger than 2 cm, LES pressure less than 8 mmHg, or Barrett's esophagus. Patients with larger hiatal hernias, LES pressure less than 8 mmHg, or Barrett's were offered LF. All patients were studied pre- and postoperatively with validated GERD-specific quality-of-life questionnaires (QOLRAD) and short-form health surveys (SF-12). Current medication use and satisfaction with the procedure was also obtained. RESULTS: Results are reported as mean +/- SEM. Seventy-five patients (age 49 +/- 14 years, 44% male, 56% female) underwent LF and 65 patients (age 46 +/- 12 years, 42%, 58% female) underwent the Stretta procedure. Preoperative esophageal acid exposure time was higher in the LF group. Preoperative LES pressure was higher in the Stretta group. In the LF group, 41% had large hiatal hernias (>2 cm), 8 patients required Collis gastroplasty, 6 had Barrett's esophagus, and 10 had undergone previous fundoplication. At 6 months, the QOLRAD and SF-12 scores were significantly improved within both groups. There was an equal magnitude of improvement between pre- and postoperative QOLRAD and SF-12 scores between Stretta and LF patients. Fifty-eight percent of Stretta patients were off proton pump inhibitors, and an additional 31% had reduced their dose significantly; 97% of LF patients were off PPIs. Twenty-two Stretta patients returned for 24-hour pH testing at a mean of 7.2 +/- 0.5 months, and there was a significant reduction in esophageal acid exposure time. Both groups were highly satisfied with their procedure. CONCLUSIONS: The addition of a less invasive, endoscopic treatment for GERD to the surgical algorithm has allowed the authors to stratify the management of GERD patients to treatment with either Stretta or LF according to size of hiatal hernia, LES pressure, Barrett's esophagus, and significant pulmonary symptoms. Patients undergoing Stretta are highly satisfied and have improved GERD symptoms and quality of life comparable to LF. The Stretta procedure is an effective alternative to LF in well-selected patients.     

Laparoscopic antireflux surgery

BACKGROUND: Several findings suggest that gastroesophageal reflux disease (GERD) has a significant impact on patients' quality of life. The aim of this prospective study was (a) to evaluate and compare quality-of-life data before and after laparoscopic antireflux surgery (LARS) in GERD patients with and without Barrett's esophagus (BE); and (b) to compare quality-of-life data of these patients to normative data for a comparable general population. METHODS: The Gastrointestinal Quality of Life Index (GIQLI) was administrated to 75 BE patients and to 174 patients with GERD without BE (Savary-Miller classification: grade 1: n = 49; grade 2: n = 69; grade 3: n = 56). The questionnaire was given to all patients preoperatively, 3months, 1 year, and 3 years after laparoscopic "floppy" Nissen fundoplication. RESULTS: Before surgery, BE patients (mean: 96.8 +/- 9.3 points) had a better but not significant (p<0.06) general score of the GIQLI when compared with patients without BE (mean: 86.4 +/- 10.1 points). This difference is solely based on the subdimension "gastrointestinal symptoms" which means that GERD symptoms are less intensively and frequently recognized in BE patients than in patients without BE. There are no other differences in the other four subdimensions of the GIQLI between both groups. Three months, 1 year, and 3 years after LARS, GIQLI was significantly (p<0.01) improved in both groups (BE patients mean after 3 years: 121.9 +/- 8.2 points; non-BE patients mean after 3 years: 122.8 +/- 9.3 points). This improvement was significantly better (p<0.05) in patients without BE than in BE patients. Before surgery, both groups scored significantly below average on all subscores of GIQLI compared to general population (mean: 122.6 +/- 8.5 points). After surgery, there are no differences detectable. CONCLUSION: As our data show, non-BE patients undergoing LARS achieve a better quality-of-life improvement than those patients with BE. However, after surgery GIQLI of both groups is comparable to the mean value of general population. This means that LARS is able to improve quality of life significantly in all GERD patients, with and without BE.     

Does Barrett's esophagus impact outcome after laparoscopic Nissen fundoplication?

BACKGROUND: This study was undertaken to compare patients with gastroesophageal reflux disease (GERD) with or without Barrett's esophagus for severity and frequency of symptoms and their response to antireflux surgery. METHODS: Eighty patients with GERD and Barrett's esophagus and 93 concurrent patients with GERD alone, all of whom underwent laparoscopic Nissen fundoplication, were compared by using symptom scores graded by a Likert scale. RESULTS: Before fundoplication, patients with Barrett's esophagus had higher DeMeester scores. Symptom scores were not different for patients with versus without Barrett's esophagus before or after laparoscopic Nissen fundoplication. CONCLUSIONS: Before and after fundoplication, patients with Barrett's esophagus, despite more severe reflux, have symptoms nearly identical in frequency and severity when compared with patients with GERD alone. Regardless of presence of Barrett's, all improve dramatically with laparoscopic Nissen fundoplication. Barrett's esophagus does not impact presentation before or outcome after laparoscopic Nissen fundoplication.     

Complete Regression of Barrett's Esophagus after Roux-en-Y Gastric Bypass

Regression of Barrett's esophagus may occur after effective anti-reflux surgery. Roux-en-Y gastric bypass (RYGBP) is an effective operation to treat morbid obesity. In addition, it provides complete relief of gastroesophageal reflux disease (GERD). Regression of Barrett's has not been reported after RYGBP. We performed a laparoscopic Roux-en-Y gastric bypass on a patient with GERD and Barrett's esophagus. At 1 year after the RYGBP, an upper endoscopy was performed as routine surveillance for the patient's Barrett's esophagus; endoscopic and histologic evaluation demonstrated complete regression of the Barrett's esophagus. The patient lost one-third of her preoperative weight and had resolution of her reflux symptoms. RYGBP limits the amount of acid reflux and completely diverts bile away from the esophagus. This may lead to the regression of Barrett's esophagus.     

Symptoms, acid exposure and motility in patients with Barrett's esophagus.

INTRODUCTION: Barrett's esophagus, a syndrome in which the squamous mucosa that normally lines the distal esophagus is replaced with columnar epithelium, is found in a small percentage of patients presenting with gastroesophageal reflux disease (GERD). The columnar epithelium may be protective, guarding people afflicted with Barrett's esophagus from experiencing symptoms related to acid reflux. The purpose of this study was to investigate whether people with Barrett's esophagus subjectively experience fewer symptoms or symptoms of decreased severity, despite sustaining greater acid exposure, than those with GERD but without Barrett's syndrome. METHODS: We conducted a chart review of patients with GERD. Criteria for inclusion in the study were esophagogastroscopy, motility testing and a 24-hour pH study. Fifty-eight patients (29 men, 29 women) fulfilled these criteria. The diagnosis of GERD was based on an abnormal 24-hour pH study (DeMeester score). Of these 58 patients, 21 (14 men, 7 women) were found to have histologically confirmed Barrett's esophagus. A questionnaire to assess the key symptoms of GERD was administered, with a severity score ranging from 0 to 3 (3 being the most severe) for each symptom. RESULTS: Patients with Barrett's esophagus experienced symptoms significantly less severe (p < 0.01) than those with GERD. Patients with Barrett's esophagus also had a greater degree of acid exposure as identified by higher DeMeester scores (p = 0.056), longer episodes of acid exposure, a greater number of long episodes (> 5 min) of acid exposure (p = 0.033) and an increased percentage of time when their pH was less than 4. Patients with Barrett's esophagus had decreased resting lower esophageal sphincter tone, and number and amplitude of peristaltic contractions. CONCLUSIONS: For patients with Barrett's esophagus, the columnar epithelium may serve a protective function in guarding against symptoms of acid reflux. This has implications for the diagnosis and management of this condition.     

Preoperative symptom evaluation and esophageal acid infusion predict response to laparoscopic Nissen fundoplication in gastroesophageal reflux patients who present with cough

BACKGROUND: Most patients with cough and gastroesophageal reflux disease (GERD) improve on medical treatment with proton pump inhibitors (PPI). Nonresponders may be considered for antireflux surgery, but the selection of patients is difficult. METHODS: We have performed laparoscopic Nissen fundoplications (LNF) in 677 patients. Of these patients, 81% have undergone 6-month follow-up assessment with 24-h pH testing, esophageal manometry, symptom scores, and quality-of-life scores. RESULTS: LNF controlled heartburn in 93% and improved cough in 81%. Stepwise multiple regression showed that the preoperative cough score (r = 0.620, p <0.0001) and change in cough on and off PPI (r = 0.296, p = 0.0002) predicted improvement after surgery. A positive result on a randomized acid infusion test was associated with a greater improvement in cough after surgery (p = 0.0243). CONCLUSION: An acid infusion test and assessment of cough on and off PPI may be useful preoperative tools for the selection of patients with cough for LNF.     

Quality of life before and after laparoscopic Nissen fundoplication

BACKGROUND: Gastroesophageal reflux disease (GERD) is a common disorder in the Western world. The acute disease can usually be managed by medical therapy. To prevent relapse, many patients require lifelong medication. In these patients, laparoscopic antireflux surgery offers a good alternative. The aim of this study was to evaluate the postoperative results and compare pre- and postoperative quality of life after laparoscopic Nissen fundoplication. METHODS: Clinical investigations, including esophageal manometry, pH monitoring, and endoscopy, and a previously validated Quality of Life Index, were performed before and a median of 41 month after antireflux surgery in 75 patients. RESULTS: After laparoscopic Nissen fundoplication, the percentage of total time with pH <4 decreased from 10.4% to 3.2% on 24-h pH monitoring. The mean pressure of the lower esophageal sphincter improved from 8.1 to 12.3 mmHg. Esophagitis healed in 63 of 66 patients in whom it was present prior to surgery. The overall Quality of Life Index improved significantly from 86 +/- 16 to 116 +/- 16. CONCLUSION: Laparoscopic fundoplication provides effective and durable relief of reflux in patients with GERD. The Quality of Life Index showed significant improvement after surgery.     

Gastroesophageal reflux and cancer

The causal relationship between GERD and esophageal adenocarcinoma, although unclear just a few decades ago, now is established fairly well. The physiologic changes and the biocellular alterations of the damaged esophageal mucosa are documented better. Despite this knowledge, the dramatic increase in the incidence of esophageal cancer cannot be explained. The absolute risk of esophageal adenocarcinoma arising from GERD is low, and, at present, does not justify population-screening programs. Still, with the notion that adenocarcinoma of the esophagus is an aggressive cancer once documented, important questions still are in need of answers for patients suffering from reflux symptoms. Patients who have reflux disease are not necessarily symptomatic. It remains unclear if patients experiencing reflux symptoms should undergo mandatory endoscopy with biopsies at the esophagogastric junction. Furthermore, metaplasia of the lower esophagus often is not readily recognizable at endoscopy, and only biopsies can document abnormal histology. A severe and prolonged history of reflux always should orient to the possibility of a reflux-related columnar-lined esophagus. Once documented, Barrett's esophagus needs to be seen as a premalignant condition not necessarily leading to adenocarcinoma formation; despite their increased risk of tumor formation, most patients who have Barrett's esophagus die of other causes. During regular endoscopic follow-up, multilevel circumferential biopsies should document the evolution of the histologic changes in the lower esophagus and at the gastroesophageal junction of these patients. It is the only method available to document the appearance of dysplasia. It still is unclear if medicine or surgery provides the best quality of life and the best protection against the development of dysplasia and the possible progression toward adenocarcinoma formation when intestinal metaplasia is present in the esophagus.     

Measuring improved quality of life after laparoscopic Nissen fundoplication

BACKGROUND: While the correction of pathologic gastroesophageal reflux by means of laparoscopic Nissen fundoplication (LNF) has been well documented, the psychological profiles of patients with this disease and the impact on their quality of life are less well understood. We obtained a baseline psychological profile and measured the impact of LNF on patients' quality of life with 2 standardized instruments: the psychological general well-being index (PGWB) and the gastrointestinal symptoms rating scale (GSRS). The study included 34 consecutive patients with typical symptoms of gastroesophageal reflux who underwent LNF in 1995 at a tertiary care university medical center. METHODS: Patients filled out PGWB and GSRS surveys preoperatively and at 2 weeks, 2 months, and 12 months postoperatively. Data were collected in a blinded fashion by a study nurse and analyzed after completion of the study. Data are expressed as mean +/- standard deviation. RESULTS: The mean preoperative PGWB score (69.6 +/- 17.3) of study patients with gastroesophageal reflux disease was lower than that expected for a healthy population. This was primarily attributable to low scores in the general health domain of the questionnaire, although LNF patients also had low scores in the vitality and positive well-being domains of the PGWB scale. LNF improved the PGWB score to a normal level (78.7 +/- 19.3) (P = .05 vs the preoperative PGWB score) at 12 months post surgery. The GSRS also showed improvement from 34.7 +/- 7.8 to 28.1 +/- 10 (P = .008). The improvement in GSRS was attributed to improvement in the heartburn (7.12 +/- 2.4 to 2.72 +/- 1.2, P < .001) and abdominal pain (6.58 +/- 2.5 to 4.92 +/- 1.6, P = .006) domains of the scale. LNF had no impact on the diarrhea, indigestion, and obstipation domains of the GSRS. CONCLUSIONS: Patients with gastroesophageal reflux disease who are candidates for LNF have low psychological and general well-being scores that are restored to normal levels by successful LNF. When compared with baseline measurements, LNF effectively relieved heartburn and did not cause significant new gastrointestinal complaints.     

Laryngopharyngeal reflux symptoms better predict the presence of esophageal adenocarcinoma than typical gastroesophageal reflux symptoms

OBJECTIVE: To determine whether the presence of laryngopharyngeal reflux symptoms is associated with the presence of esophageal adenocarcinoma (EAC). BACKGROUND: Most patients diagnosed with EAC have incurable disease at the time of detection. The majority of these patients are unaware of the presence of Barrett's esophagus prior to cancer diagnosis and many do not report typical symptoms of gastroesophageal reflux disease (GERD). This suggests that the current GERD symptom-based screening paradigm may be inadequate. Data support a causal relation between complicated GERD and laryngopharyngeal reflux symptoms. We theorize that laryngopharyngeal reflux symptoms are not recognized expeditiously, resulting in chronic esophageal injury and an unrecognized progression of Barrett's esophagus to EAC. METHODS: This is a case-comparison (control) study. Cases were patients diagnosed with EAC (n = 63) between 1997 and 2002. Three comparison groups were selected: 1) Barrett's esophagus patients without dysplasia (n = 50), 2) GERD patients without Barrett's esophagus (n = 50), and 3) patients with no history of GERD symptoms or antisecretory medication use (n = 56). The risk factors evaluated included demographics, medical history, lifestyle variables, and laryngopharyngeal reflux symptoms. Typical GERD symptoms and antisecretory medication use were recorded. Multivariate analysis of demographics, comorbid risk factors, and symptoms was performed with logistic regression to provide odds ratios for the probability of EAC diagnosis. RESULTS: The prevalence of patients with laryngopharyngeal reflux symptoms was significantly greater in the cases than comparison groups (P = 0.0005). The prevalence of laryngopharyngeal reflux symptoms increased as disease severity progressed from the non-GERD comparison group (19.6%) to GERD (26%), Barrett's esophagus (40%), and EAC patients (54%). Symptoms of GERD were less prevalent in cases (43%) when compared with Barrett's esophagus (66%) and GERD (86%) control groups (P < 0.001). Twenty-seven percent (17 of 63) of EAC patients never had GERD or laryngopharyngeal reflux symptoms. Fifty-seven percent of EAC patients presented without ever having typical GERD symptoms. Chronic cough, diabetes, and age emerged as independent risk factors for the development of EAC. CONCLUSIONS: Symptoms of laryngopharyngeal reflux are more prevalent in patients with EAC than typical GERD symptoms and may represent the only sign of disease. Chronic cough is an independent risk factor associated with the presence of EAC. Addition of laryngopharyngeal reflux symptoms to the current Barrett's screening guidelines is warranted.     

Comparison of patient-centered outcomes after laparoscopic Nissen fundoplication for gastroesophageal reflux disease or paraesophageal hernia

Background Patients undergoing laparoscopic Nissen fundoplication (LNF) with paraesophageal hernias (PEH) are not only older and less healthy than those with gastroesophageal reflux disease (GERD), but in addition the repair is more complicated. We evaluated whether outcomes relating to GERD symptoms and quality of life (QOL) were impacted by the presence of PEH. Methods Prospectively entered data from 149 patients (109 GERD and 40 PEH) were evaluated prior to and one year after LNF with standardized and validated symptoms scores. Scores for heartburn, dysphagia, disease-specific QOL (GERD-HRQL), and general health-related QOL (SF-12 physical and mental component scores) were compared between patients undergoing LNF for PEH or for GERD alone, at baseline and one year after surgery. p < 0.05 was considered statistically significant. Results Preoperative data for GERD-HRQL, heartburn, and dysphagia were available for 134 patients, with 96% one-year follow-up. SF-12 data were collected for 98 patients with 100% follow-up. PEH patients were older and had greater comorbidity. Preoperative GERD-HRQL and heartburn were significantly worse in the GERD group. One year after surgery, both GERD and PEH patients showed significant improvement in GERD-HRQL, heartburn and dysphagia scores, with no difference in any of these disease or symptom measures between the two study groups. Postoperative PCS and MCS scores showed improvement in GERD patients, while PEH patient scores remained at or below the population mean. Conclusions LNF is equally effective as an antireflux procedure in both GERD and PEH patients, prevents symptoms of reflux in PEH patients that have none preoperatively, and does not increase dysphagia in either group. Despite the increased complexity of the procedure, LNF provides an effective control of reflux symptoms in patients undergoing PEH repair.

Comparison of laparoscopic and open Nissen fundoplication 2 years after operationrid=""

BACKGROUND: Laparoscopic operation has replaced the conventional open procedure in the treatment of gastroesophageal reflux disease (GERD) in spite of the fact that long-term results based on controlled clinical trials have been lacking. The objective of this study was to compare outcome, quality of life, and patient satisfaction after laparoscopic and open Nissen fundoplication in a community hospital setting with a 2-year follow-up. METHODS: Forty-two patients with GERD were randomized to either laparoscopic (LNF) or open (ONF) Nissen fundoplication. Outcome evaluation included reflux symptoms, gastrointestinal quality of life (GIQLI), and upper GI endoscopy. RESULTS: Esophagitis was cured among all patients in the LNF group and in 90% of the ONF group. There were two patients (10%) in both groups who had medicine-dependent recurrent reflux together with significant worsening in the GIQLI scores. One patient in the LNF group has been reoperated due to a suture granuloma in the left epigastric port. Two patients in the LNF group needed esophageal dilatation due to persistent dysphagia. GIQLI scores (scale, 0-144) were equally normalized in both groups. Overall, 90% in the LNF and 100% in the ONF group were either satisfied or very satisfied with the operation. There was only one patient (LNF) who would not choose to have the operation again. CONCLUSIONS: Laparoscopic and open Nissen fundoplication seem to be equally effective methods for improving reflux symptoms and quality of life, resulting in a high rate of satisfaction among patients with an intermediate follow-up period of 2 years.     

Gastric fluid bile concentrations and risk of Barrett's esophagus

Patients with Barrett's esophagus are at high risk of progression to adenocarcinoma. A growing, but conflicting body of evidence implicates bile reflux as a contributor to Barrett's esophagus. To investigate whether duodenogastric reflux was associated with an increased risk of Barrett's esophagus, a case-control study of incident Barrett's esophagus was performed. Cases (n=72) were identified by new histologically-confirmed diagnosis of specialized intestinal metaplasia (indicative of Barrett's esophagus) following upper endoscopy for refractory gastroesophageal reflux between October 1997 and September 2000. Cases were compared to gastroesophageal reflux patients without specialized intestinal metaplasia (controls; n=72). There was no difference in total bile acid concentrations between cases and controls. Risk of Barrett's esophagus did not significantly vary with increasing concentrations of total or free bile acids, respectively (OR 0.35 (95% CI 0.12, 1.02) and 0.60 (95% CI 0.22, 1.66)). Low gastric fluid pH (toxic range 3-5), was associated with a non-significant increase in the risk of Barrett's esophagus. In conclusion, no significant association between Barrett's esophagus and total or free bile acids in gastric refluxate was found. Patients with low gastric fluid pH (3-5) may represent a subset of patients at high risk of developing Barrett's esophagus.     

A new physiologic approach for the surgical treatment of patients with Barrett''s esophagus: technical considerations and results in 65 patients.

OBJECTIVE: To determine the results of a new surgical procedure for patients with Barrett's esophagus. SUMMARY BACKGROUND DATA: In addition to pathologic acid reflux into the esophagus in patients with severe gastroesophageal reflux and Barrett's esophagus, increased duodenoesophegeal reflux has been implicated. The purpose of this study was to establish the effect of a new bile diversion procedure in these patients. METHODS: Sixty-five patients with Barrett's esophagus were included in this study. A complete clinical, radiologic, endoscopic, and bioptic evaluation was performed before and after surgery. Besides esophageal manometry, 24-hour pH studies and a Bilitec test were performed. After surgery, gastric emptying of solids, gastric acid secretion, and serum gastrin were determined. All patients underwent highly selective vagotomy, antireflux procedure (posterior gastropexy with cardial calibration or fundoplication), and duodenal switch procedure, with a Roux-en-Y anastomosis 60 cm in length. RESULTS: No deaths occurred. Morbidity occurred in 14% of the patients. A significant improvement in symptoms, endoscopic findings, and radiologic evaluation was achieved. Lower esophageal sphincter pressure increased significantly (p < 0.0001), as did abdominal length and total length of the sphincter (p < 0.0001). The presence of an incompetent sphincter decreased from 87.3% to 20.9% (p < 0.0001). Three of seven patients with dysplasia showed disappearance of this dysplasia. Serum gastrin and gastric emptying of solids after surgery remained normal. Basal and peak acid output values were low. Twenty-four hour pH studies showed a mean value of 24.8% before surgery, which decreased to 4.8% after surgery (p < 0.0001). The determination of the percentage time with bilirubin in the esophagus was 23% before surgery; this decreased to 0.7% after surgery (p < 0.0001). Late results showed Visick I and II gradation in 90% of the patients and grade III and IV in 10% of the patients. CONCLUSIONS: This physiologic approach to the surgical treatment of patients with Barrett's esophagus produces a permanent decrease of acid secretion (and avoids anastomotic ulcer), decreases significantly acid reflux into the esophagus, and abolishes duodenoesophageal reflux permanently. Significant clinical improvement occurs, and dysplastic changes at Barrett's epithelium disappear in almost 50% of the patients.     

Long-term clinical and pathologic response of Barrett's esophagus after antireflux surgery

BACKGROUND: The impact of antireflux surgery on outcome in Barrett's esophagus, in particular its effect on both the regression of metaplasia and the progression of metaplasia through dysplasia to adenocarcinoma, remains unclear. This long-term follow-up study evaluated clinical, endoscopic, histopathologic, and physiologic parameters in patients with Barrett's esophagus who underwent antireflux surgery in a specialist unit. METHODS: Between 1985 and 2001, 58 patients with Barrett's esophagus (49 long-segment and 9 short-segment) underwent a Rossetti-Nissen fundoplication, 32 via open procedure and 26 laparoscopically. Symptomatic follow-up with a detailed questionnaire was available in 58 (100%) and follow-up endoscopy and histology in 57 (98%) patients, and 41 patients (71%) underwent preoperative and postoperative 24-hour pH monitoring. RESULTS: At a median follow-up of 59 months, 52 patients (90%) had excellent symptom control, whereas 6 patients (10%) had significant recurrent symptoms and were on regular proton pump inhibitor medication. Seventeen of 41 patients having preoperative and postoperative pH monitoring (41%) had a persistent increase of acid reflux above normal. Thirty-five percent (20 of 57) of patients showed either partial or complete regression of Barrett's epithelium. Six of 8 patients with preoperative low-grade dysplasia showed evidence of regression. Dysplasia developed after surgery in 2 patients, and 2 patients developed adenocarcinoma at 4 and 7 years after surgery. All 4 of these patients had abnormal postoperative acid scores. CONCLUSIONS: Nissen fundoplication provides excellent long-lasting relief of symptoms in patients with Barrett's esophagus and may promote regression of metaplasia and dysplasia. Control of symptoms does not concord fully with abolition of acid reflux. Progression of Barrett's to dysplasia and tumor was only evident in patients with abnormal postoperative acid scores, suggesting that pH monitoring has an important role in the follow-up of surgically treated patients.     

Efficacy of laparoscopic antireflux surgery in patients with Barrett's esophagus

BACKGROUND: Laparoscopic antireflux surgery (LARS) corrects significant physiologic and anatomic abnormalities in patients with gastroesophageal reflux disease (GERD); however, debate exists whether LARS prevents recurrent symptoms and malignant transformation in patients with Barrett's esophagus (BE). This study compared clinical outcomes after LARS in patients with and without BE. METHODS: From 1994 to 2001, 448 patients who underwent LARS were studied. Of these, 68 (15%) had preoperative evidence of BE with low-grade dysplasia in 3 (4%), and 380 (85%) were without BE. Mean postoperative follow-up was more than 30 months in each group. RESULTS: After LARS, there was equivalent reduction in acid reduction medication use and typical GERD symptoms in both groups. Anatomic failures developed in 12% of patients with BE and in 5% of those without BE (P = 0.05). Upper endoscopy with biopsies was obtained in 50 of 68 patients (74%) with BE at 37 +/- 22 months postoperatively. Intestinal metaplasia was no longer present in 7 of 50 (14%) BE patients, and low-grade dysplasia regressed to nondysplastic Barrett's in 2 of 3 patients. New low-grade dysplasia developed in 1 BE patient (2%) at postoperative endoscopic surveillance. No BE patients developed high-grade dysplasia or adenocarcinoma. CONCLUSIONS: After LARS, patients with BE have symptomatic relief and reduction in medication use equivalent to non-BE patients. Regression of intestinal metaplasia and the absence of progression to high-grade dysplasia or adenocarcinoma suggest that LARS is an effective approach for the management of patients with Barrett's esophagus. The higher failure rate of LARS in BE is of concern and mandates ongoing follow-up of these patients.     

Laparoscopic versus open fundoplication in infants

BACKGROUND: Laparoscopic esophagogastric fundoplication is an effective treatment for severe gastroesophageal reflux disease (GERD), although its role in the very young is still largely undetermined. We review our surgical outcome in infants with severe GERD, comparing laparoscopic (LNF) with open (ONF) Nissen fundoplication. METHODS: This study reviewed 55 consecutive Nissen fundoplications performed for GERD on infants less than 1 year old at our institution between January 1996 and June 2000. The follow-up period for LNF averaged 14.2 months (range, 3.3-42 months), as compared with 16.5 months (range, 1-37.1 months) for ONF (p was not significant, t-test). Surgical outcome was compared in terms of the following parameters: average operative time, times to initiation and completion of feeding schedule, postoperative complications, and recurrence rates. RESULTS: For the study, 53 infants were divided into two groups: LNF (n = 39; 73.6%) and ONF (n = 14; 26.4%). The average operating time for LNF was 120 +/- 24 min (range, 60-195 min), as compared with 91 +/- 21 min (range, 60-135 min) for ONF (p < 0.05, t-test). Time to initiation of postoperative feeding schedule was 1.3 +/- 0.3 days for LNF, as compared with 3 +/- 0.9 days for ONF (p < 0.05, t-test). Full feedings were reached in 1.7 +/- 0.6 days for LNF, as compared with 1.3 +/- 0.9 for ONF (p was not significant, t-test). During the short-term follow-up period, recurrent reflux developed in 2/14 ONF patients (14.3%) as compared with 1/39 LNF patients (2.6%) (p < 0.05). CONCLUSIONS: We conclude that in addition to sparing infants the morbidity of celiotomy, laparoscopic Nissen fundoplication had a surgical outcome comparable to that of traditional open fundoplication in infants with severe GERD. Importantly, resumption of goal nutritional regimens was equally efficient in both groups.     

Treatment of Barrett''s esophagus by endoscopic laser ablation and antireflux surgery.

OBJECTIVE: The regeneration of intestinal metaplasia by squamous epithelium in 17 patients with Barrett's esophagus after endoscopic laser ablation in a reflux-free environment after successful antireflux surgery was prospectively examined. METHODS: All patients had antireflux surgery, and healing of reflux was verified at postoperative endoscopy and 24-hour esophageal pH monitoring. Thereafter, in 11 patients, the whole Barrett's epithelium was ablated using endoscopic Nd-YAG laser energy in 1 to 8 sessions (mean, 4). The needed energy was 965 to 11,173 joules (mean 4709), or about 1000 joules per centimeter of Barrett's esophagus. Six patients had no laser ablation but were treated by antireflux surgery and served as a control group. RESULTS: In all laser-treated patients, the regenerated epithelium was histologically of squamous type in the tubular esophagus, but two patients still had intestinal metaplasia in the gastric cardia. In controls, the length of Barrett's esophagus and intestinal metaplasia remained unchanged. The length of follow-up was 26 months after the last laser session and 21 months in the control group. CONCLUSIONS: The regenerated esophageal epithelium arising after laser ablation in reflux-free environment surgery is of squamous type. This treatment may have a role in preventing the development of esophageal adenocarcinoma arising in Barrett's esophagus.     

Alkaline gastroesophageal reflux: implications in the development of complications in Barrett's columnar-lined lower esophagus

Barrett's esophagus is a common finding in patients with gastroesophageal reflux and is associated with a high incidence of serious complications (stricture, ulceration, and carcinoma). The reason that only a portion of patients with reflux develop Barrett's esophagus and why some are prone to develop complications is unknown. Twenty-three patients with Barrett's esophagus underwent endoscopy, 24-hour esophageal pH monitoring, and manometry. Nine of these patients with gastritis underwent 24-hour gastric pH monitoring, and three with symptoms of duodenogastric reflux underwent 99mTc-labeled hepato-iminodiacetic acid scanning. Patients with complicated (n = 12) and uncomplicated (n = 11) Barrett's esophagus were compared with each other and with patients with reflux esophagitis (n = 53) and normal volunteers (n = 50). Patients with Barrett's esophagus showed an increased exposure to acid and alkaline gastric juice compared with patients with esophagitis and normal volunteers. In the patients with Barrett's esophagus with and without complications, there was no significant difference in age, incidence of defective lower esophageal sphincter, incidence of defective peristalsis, extent of the Barrett's epithelium, or percent time the esophageal pH was less than 4. In contrast, the percent time the esophageal pH was greater than 7 was significantly greater in patients with complications. This alkaline exposure is likely to be related to duodenogastric reflux. This was supported by positive gastric pH scores for duodenogastric reflux and 99mTc-labeled hepato-iminodiacetic acid scans in patients with Barrett's complications. These findings suggest that the development of complications in Barrett's esophagus is the result of the damaging effect of refluxed duodenal juice.
