Population-based trend analysis of laparoscopic Nissen and Toupet fundoplications for gastroesophageal reflux disease

The Nissen and Toupet fundoplications are the most commonly used techniques for surgical treatment of gastroesophageal reflux disease. To date, no population-based trend analysis has been reported examining the choice of procedure and short-term outcomes. This study was designed to analyze trends in the use of Nissen versus Toupet fundoplications, and corresponding short-term outcomes during a 10-year period between 1995 and 2004.

Dental erosion and salivary flow rate in cerebral palsy individuals with gastroesophageal reflux

A high prevalence of gastroesophageal reflux (GERD) has been observed in individuals with cerebral palsy (CP). One of the main risks for dental erosion is GERD. This study aimed to evaluate the presence of GERD, variables related to dental erosion and associated with GERD (diet consumption, gastrointestinal symptoms, bruxism), and salivary flow rate, in a group of 46 non-institutionalized CP individuals aged from 3 to 13 years.

Gastroesophageal reflux and pulmonary fibrosis in scleroderma: a study using pH-impedance monitoring

RATIONALE: Interstitial lung disease (ILD) in patients with systemic sclerosis (SSc) is associated with increased morbidity and mortality. Gastroesophageal reflux (GER) is considered a contributing factor in the pathogenesis of ILD. OBJECTIVES: To characterize GER (acid and nonacid) in patients with SSc with and without ILD. METHODS: Patients with SSc underwent pulmonary high-resolution computer tomography (HRCT) scan and 24-hour impedance-pH monitoring off-proton pump inhibitor therapy. The presence of pulmonary fibrosis was assessed using validated HRCT-scores. Reflux monitoring parameters included number of acid and nonacid reflux episodes, proximal migration of the refluxate, and distal esophageal acid exposure. Unless otherwise specified, data are presented as median (25th-75th percentile). MEASUREMENTS AND MAIN RESULTS: Forty consecutive patients with SSc (35 female; mean age, 53 yr; range, 24-71; 15 patients with diffuse and 25 with limited SSc) were investigated; 18 (45%) patients with SSc had pulmonary fibrosis (HRCT score >or= 7). Patients with SSc with ILD had higher (P < 0.01) esophageal acid exposure (10.3 [7.5-15] vs. 5.2 [1.5-11]), higher (P < 0.01) number of acid (41 [31-58] vs. 19 [10-23]) and nonacid (25 [20-35] vs. 17 [11-19]) reflux episodes, and higher (P < 0.01) number of reflux episodes reaching the proximal esophagus (42.5 [31-54] vs. 15 [8-22]) compared with patients with SSc with normal HRCT scores. Pulmonary fibrosis scores (HRCT score) correlated well with the number of reflux episodes in the distal (r(2) = 0.637) and proximal (r(2) = 0.644) esophagus. CONCLUSIONS: Patients with SSc with ILD have more severe reflux (i.e., more reflux episodes and more reflux reaching the proximal esophagus). Whether or not the development of ILD in patients with SSc can be prevented by reflux-reducing treatments needs to be investigated.

Halitosis and tongue coating in patients with erosive gastroesophageal reflux disease versus nonerosive gastroesophageal reflux disease

OBJECTIVE The aim of this study was to investigate whether patients with diagnosed erosive gastroesophageal reflux disease (ERD) have an increased probability of halitosis and tongue coating compared to patients with nonerosive gastroesophageal reflux disease (NERD). MATERIALS AND METHODS Sixty-six patients (33 males and 33 females) were recruited for the study and received an upper gastrointestinal endoscopy. The presence of ERD (n = 31) and NERD (n = 35) was classified based on the Los Angeles classification for erosive changes in the esophagus. Additionally, the patients filled in a questionnaire regarding their subjective assessment of halitosis, and an organoleptic assessment of halitosis, a measurement of oral volatile sulfur compounds (VSC) with the Halimeter, and a tongue coating index were performed. ERD and NERD subjects were compared with regard to Halitosis-related clinical and anamnestic findings. RESULTS No statistically significant difference could be found between ERD and NERD patients regarding tongue coating index, organoleptic scores, and VSC values as well as self-perceived bad taste, tongue coating, and bad breath. CONCLUSIONS These data suggest that halitosis is not typically associated with erosive gastroesophageal reflux disease and the presence of esophageal mucosal damage (ERD patients). CLINICAL RELEVANCE The data of this investigation support the findings of interdisciplinary bad breath clinics that gastroesophageal reflux disease is not a leading cause for halitosis.

Effects of bariatric surgery on gastroesophageal reflux

PURPOSE OF REVIEW: Obesity and gastroesophageal reflux disease (GERD) are two prevalent conditions with important impact on health resource utilization around the world. Obesity is a known risk factor in the pathogenesis of GERD. When conservative measures fail, bariatric surgery remains the only option to lose weight and correct obesity-related comorbidities. The influence of bariatric surgery on GERD depends on which bariatric intervention is used. RECENT FINDINGS: Recent studies indicate that laparoscopic gastric banding and laparoscopic sleeve gastrectomy have little influence on preexisting GERD symptoms and findings, but some patients may develop GERD after laparoscopic sleeve gastrectomy. A number of studies have documented that laparoscopic Roux-en-Y gastric bypass improves GERD symptoms and findings, making it the preferred procedure for morbid obese patients with concomitant GERD. SUMMARY: Current findings provide good arguments for searching for and treating GERD in patients scheduled to undergo bariatric surgery. The presence of GERD might represent a relative contraindication for sleeve gastrectomy or gastric banding or both. Gastric bypass might be the procedure of choice in morbid obese patients with GERD symptoms or findings or both.

Sensitivity and specificity of the Gastrointestinal Short Form Questionnaire in diagnosis of gastroesophageal reflux disease

Introduction: Gastrointestinal Short Form Questionnaire (GSFQ) is a questionnaire for gastroesophageal reflux disease (GERD) diagnosis, with a version in Spanish language, not yet compared to an objective test. Aims: To establish GSFQ diagnostic performance against 24-hour pH monitoring carried out in two tertiary care hospitals. Methods: Consecutive adult patients with typical GERD symptoms (heartburn, regurgitation) referred for pH monitoring fulfilled the GSFQ (score range 0-30, proportional to probability of GERD). Diagnosis of GERD was established when acid exposure time in distal esophagus was superior to 4.5% or symptom association probability was greater than 95%. Receiver-operator characteristic (ROC) curves were calculated and best cut-off score determined, with corresponding sensitivity, specificity and likelihood ratios (LR) (95% confidence interval for each). Results: One hundred and fifty-two patients were included (59.9% women, age 47.9 ± 13.9; 97.4% heartburn; 71.3% regurgitation). pH monitoring was abnormal in 65.8%. Mean GSFQ score was 11.2 ± 6. Area under ROC was 56.5% (47.0-65.9%). Optimal cut-off score was 13 or greater: sensitivity 40% (30.3-50.3%), specificity 71.2% (56.9-82.9%), positive LR 1.39 (0.85-2.26) and negative LR 0.84 (0.67-1.07). Exclusion of questions 1 and 3 of the original GSFQ, easily interpreted as referred to dyspepsia and not GERD, improved only marginally the diagnostic performance: AUROC 59.1%. Conclusion: The GSFQ does not predict results of pH monitoring in patients with typical symptoms in a tertiary care setting.

Use of multiple channel pH monitoring for evaluation of ultra-distal reflux in patients after fundoplication for treatment of Barrett`s esophagus

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

Presentations of physical illness in people with developmental disability: the example of gastro-oesophageal reflux

People with developmental disabilities are becoming an important part of the general practice population. Although they have a similar range of medical conditions to the general population, there are some important differences in prevalence, risk factors, presentation and management of particular conditions. We use gastro-oesophageal reflux to illustrate how developmental disability may affect the presentation, assessment and management of a common condition.

Prevalence and risk factors for gastro-esophageal reflux disease in the North-Eastern part of Bangladesh.

Despite a common disorder population-based data on gastro-esophageal reflux disease (GERD) in Bangladesh is lacking. This epidemiological study was designed to determine the prevalence of GERD and its association with lifestyle factors. This population-based cross-sectional study was done by door to door interview of randomly selected persons in both urban and rural areas of North Eastern part of Bangladesh by using a validated questionnaire. A cutoff point 3 was chosen as a valid and reliable scale to confirm GERD. Statistical analysis was done by SPSS-12 version and the level of significance was set at P < or = 0.05. A total of 2000 persons with an age range of 15 to 85 years were interviewed; 1000 subjects from urban area and 1000 from rural area. Among the study subjects 1064 were male and 936 were female. A total of 110 persons (5.5%) were found to have GERD symptoms and among them 47 were men and 67 were women. The monthly, weekly and daily prevalence of heart-burn and or acid regurgitation was 5.5%, 5.25% and 2.5% respectively. Female sex, increased age and lower level of education were significantly associated with GERD symptoms. Prevalence was found more among city dwellers (approximately 6.0% versus 4.8%), married (6.23%, n = 86), widowed/widowers (16.83%, n = 17) and day labourer (8.78%). Level of education inversely influenced the prevalence. No significant association of GERD was found with body mass index (BMI) and smoking. Prevalence of GERD in North-Eastern part of Bangladesh was lower than that of western world. Prevalence was found higher in urban population, women, married, widowed/widowers and in poor an dilliterate persons. BMI and smoking had no significant association with GERD.

Predictive factors in the long term outcome in gastro-oesophageal reflux disease: six years follow up of 107 patients

There is little information concerning the long term outcome of patients with gastro-oesophageal reflux disease (GORD). Thus 109 patients with reflux symptoms (33 with erosive oesophagitis) with a diagnosis of GORD after clinical evaluation and oesophageal testing were studied. All patients were treated with a stepwise approach: (a) lifestyle changes were suggested aimed at reducing reflux and antacids and the prokinetic agent domperidone were prescribed; (b) H2 blockers were added after two months when symptoms persisted; (c) anti-reflux surgery was indicated when there was no response to (b). Treatment was adjusted to maintain clinical remission during follow up. Long term treatment need was defined as minor when conservative measures sufficed for proper control, and as major if daily H2 blockers or surgery were required. The results showed that one third of the patients each had initial therapeutic need (a), (b), and (c). Of 103 patients available for follow up at three years and 89 at six years, respective therapeutic needs were minor in 52% and 55% and major in 48% and 45%. Eighty per cent of patients in (a), 67% in (b), and 17% in (c) required only conservative measures at six years. A decreasing lower oesophageal sphincter pressure (p < 0.001), radiological reflux (p = 0.028), and erosive oesophagitis (p = 0.031), but not initial clinical scores, were independent predictors of major therapeutic need as shown by multivariate analysis. The long term outcome of GORD is better than previously perceived.

Le reflux gastro-oesophagien de l'enfant: indications chirurgicales, techniques et suivi.

Contexte: Présent sous forme physiologique chez environ 60% des nourrissons normaux de moins de quatre mois, le reflux gastro-oesophagien (RGO) n'est symptomatique que chez 10% d'entre eux. Il est également plus fréquent chez les enfants atteints de troubles neurologiques quelque soit leur âge. Non traité, il peut avoir des conséquences graves (oesophagite, sténose peptique, endobrachyoesophage (Barrett) puis adénocarcinome de l'oesophage). Il s'agit donc d'un problème qu'il faut savoir détecter et traiter précocement. Les signes et symptômes du RGO sont multiples et varient en fonction de l'âge. Ils ne se limitent pas au seul vomissement. Le traitement initial du RGO chez l'enfant est médical. En cas d'échec de celui-ci ou dans certaines indications (comme les RGO récidivants, les malformations congénitales, les anomalies morphologiques ou les pathologies neurologiques) un traitement chirurgical est nécessaire. L'évolution des traitements conservateurs et des techniques chirurgicales lors de ces dernières années en font un bon sujet pour une étude rétrospective. Objectif: Le but de cette étude est de mettre en évidence dans une population d'enfants ayant bénéficié d'une cure chirurgicale anti-reflux la fréquence relative des symptômes selon la pathologie initiale de l'enfant, puis de préciser le choix de traitement et sa durée. Nous analyserons également les risques d'échec qui s'y rapportent. Ces conclusions devraient nous permettre de proposer un algorithme décisionnel de prise en charge du RGO de l'enfant en pré et post-opératoire. Méthodologie: Étude rétrospective sur 9 ans se basant sur les dossiers médicaux-chirurgicaux de 132 enfants opérés d'un reflux gastro-oesophagien dans le Service de Chirurgie Pédiatrique du Centre Hospitalier Universitaire Vaudois (CHUV) par le Professeur Olivier Reinberg et son équipe entre le 1er janvier 2003 et le 31 décembre 2012. Résultats: Sur les 132 enfants, 93 ont bénéficié d'une fundoplicature selon Toupet, 34 selon Nissen et 5 selon Dor. 57% des enfants présentant un déficit neurologique ont été opérés selon la technique de Nissen contre 7% des enfants "sains". Les taux de démontage et de récidive sont respectivement 5.4% et 3.5 % pour la technique selon Toupet et 2.9% et 0% pour la technique de Nissen. Le taux de démontage global de la fundoplicature est de 4.6% (N=6) Conclusions: La fundoplicature est une méthode de choix pour les enfants chez qui tous les autres traitements ont échoué ou chez qui la présence concomitante du RGO et des comorbidités est délétère à une croissance harmonieuse. Grâce à la chirurgie, la qualité de vie d'au moins 95% des enfants est grandement améliorée après la disparition de symptômes quotidiens et qui peuvent donner lieu à des complications graves.
