Overlapping approach Proton Pump Inhibitors/Nux vomica-Heel as new intervention for gastro-esophageal reflux management:Delphi consensus study

BACKGROUND Gastro-esophageal reflux disease(GERD)may affect the upper digestive tract;up to 20%of population in Western nations are affected by GERD.Antacids,histamine H2-receptor antagonists,and Proton Pump Inhibitors(PPIs)are considered the referring medications for GERD.Nevertheless,PPIs must be managed carefully because their use,especially chronic,could be linked with some adverse effects.An effective and safe alternative pharmacological tool for GERD is needed.After the identification of potentially new medications to flank PPIs,it is mandatory to revise and improve good clinical practices even through a consensus process.AIM To optimize diagnosis and treatment guidelines for GERD through a consensus based on Delphi method.METHODS The availability of clinical studies describing the action of the multicomponent/multitarget medication Nux vomica-Heel,subject of the consensus,is the basic prerequisite for the consensus itself.A modified Delphi process was used to reach a consensus among a panel of Italian GERD specialists on the overlapping approach PPIs/Nux vomica-Heel as a new intervention model for the management of GERD.The Voting Consensus group was composed of 49 Italian Medical Doctors with different specializations:Gastroenterology,otolaryngology,geriatrics,and general medicine.A scientific committee analyzed the literature,determined areas that required investigation(in agreement with the multiple-choice questionnaire results),and identified two topics of interest:(1)GERD disease;and(2)GERD treatment.Statements for each of these topics were then formulated and validated.The Delphi process involved two rounds of questioning submitted to the panel experts using an online platform.RESULTS According to their routinary GERD practice and current clinical evidence,the panel members provided feedback to each questionnaire statement.The experts evaluated 15 statements and reached consensus on all 15.The statements regarding the GERD disease showed high levels of agreement,with consensus ranging from 70%to 92%.The statements regarding the GERD treatment also showed very high levels of agreement,with consensus ranging from 90%to 100%.This Delphi process was able to reach consensus among physicians in relevant aspects of GERD management,such as the adoption of a new approach to treat patients with GERD based on the overlapping between PPIs and Nux vomica-Heel.The consensus was unanimous among the physicians with different specializations,underlying the uniqueness of the agreement reached to identify in the overlapping approach between PPIs and Nux vomica-Heel a new intervention model for GERD management.The results support that an effective approach to deprescribe PPIs through a progressive decalage timetable(reducing PPIs administration to as-needed use),should be considered.CONCLUSION Nux vomica-Heel appears to be a valid opportunity for GERD treatment to favor the deprescription of PPIs and to maintain low disease activity together with the symptomatology remission.

Mean nocturnal baseline impedance in gastro-esophageal reflux disease diagnosis:Should we strictly follow the Lyon 2 Consensus?

Clinical practice guidelines drive clinical practice and clinicians rely to them when trying to answer their most common questions.One of the most important position papers in the field of gastro-esophageal reflux disease(GERD)is the one produced by the Lyon Consensus.Recently an updated second version has been released.Mean nocturnal baseline impedance(MNBI)was proposed by the first Consensus to act as supportive evidence for GERD diagnosis.Originally a cut-off of 2292 Ohms was proposed,a value revised in the second edition.The updated Consensus recommended that an MNBI<1500 Ohms strongly suggests GERD while a value>2500 Ohms can be used to refute GERD.The proposed cut-offs move in the correct direction by diminishing the original cut-off,nevertheless they arise from a study of normal subjects where cut-offs were provided by measuring the mean value±2SD and not in symptomatic patients.However,data exist that even symptomatic patients with inconclusive disease or reflux hypersensitivity(RH)show lower MNBI values in comparison to normal subjects or patients with functional heartburn(FH).Moreover,according to the data,MNBI,even among symptomatic patients,is affected by age and body mass index.Also,various studies have proposed different cut-offs by using receiver operating characteristic curve analysis even lower than the one proposed.Finally,no information is given for patients submitted to on-proton pump inhibitors pH-impedance studies even if new and extremely important data now exist.Therefore,even if MNBI is an extremely important tool when trying to approach patients with reflux symptoms and could distinguish conclusive GERD from RH or FH,its values should be interpreted with caution.

Management of gastro-esophageal reflux disease:Practice-oriented answers to clinical questions

Gastro-esophageal reflux disease(GERD)is a condition which is frequently faced by primary care physicians and gastroenterologists.Improving management of GERD is crucial to maximise both patient care and resource utilization.In fact,the management of patients with GERD is complex and poses several questions to the clinician who faces them in clinical practice.For instance,many aspects should be considered,including the appropriateness of indication to endoscopy,the quality of the endoscopic examination,the use and interpretation of ambulatory reflux testing,and the choice and management of anti-reflux treatments,i.e.,protonpump inhibitors and surgery.Aim of the present review was to provide a comprehensive update on the clinical management of patients with GERD,through a literature review on the diagnosis and management of patients with GER symptoms.In details,we provide practice-oriented concise answers to clinical questions,with the aim of optimising patient management and healthcare resource use.

Outcome of nonerosive gastro-esophageal reflux disease patients with pathological acid exposure

AIM： To assess the management and outcome of nonerosive gastro-esophageal reflux disease （NERD） patients who were identified retrospectively, after a 5-year follow-up. METHODS： We included patients with gastro-esophageal reflux disease （GERD） symptoms who had a negative endoscopy result and pathological 24-h esophageal pH-monitoring while off therapy. We interviewed them after an average period of 5 years （range 3.5-7 years） by means of a structured questionnaire to assess presence of GERD symptoms, related therapy, updated endoscopic data and other features. We assessed predictors of esophagitis development by means of univariate and multivariate statistical analysis. RESULTS： 260 patients （137 women） were included. Predominant GERD symptoms were heartburn and regurgitation in 103/260 （40%）. 70% received a maintenance treatment, which was proton pump inhibitor （PPI） in 55% of cases. An average number of 1.5 symptomatic relapses per patient/year of follow-up were observed. A progression to erosive gastro-esophageal reflux disease （ERD） was found in 58/193 （30.0%） of patients undergoing repeat endoscopy; 72% of these were Los Angeles grade A-B. CONCLUSION： This study to ERD occurs in about 5% shows that progression of NERD cases per year, despite therapy. Only two factors consistently and independently influence progression： smoking and absence of PPI therapy.

Clinical usefulness of adherence to gastro-esophageal reflux disease guideline by Spanish gastroenterologists

AIM:To investigate usefulness of adherence to gastroesophageal reflux disease(GERD) guideline established by the Spanish Association of Gastroenterology.METHODS:Prospective,observational and multicentre study of 301 patients with typical symptoms of GERD who should be managed in accordance with guidelines and were attended by gastroenterologists in daily practice.Patients(aged > 18 years) were eligible for inclusion if they had typical symptoms of GERD(heartburn and/or acid regurgitation) as the major complaint in the presence or absence of accompanying atypical symptoms,such as dyspeptic symptoms and/or supraesophageal symptoms.Diagnostic and therapeutic decisions should be made based on specific recommendations of the Spanish clinical practice guideline for GERD which is a widely disseminated and well known instrument among Spanish in digestive disease specialists.RESULTS:Endoscopy was indicated in 123(41%) patients:50 with alarm symptoms,32 with age > 50 years without alarm symptom.Seventy-two patients(58.5%) had esophagitis(grade A,23,grade B,28,grade C,18,grade D,3).In the presence of alarm symptoms,endoscopy was indicated consistently with recommendations in 98% of cases.However,in the absence of alarm symptoms,endoscopy was indicated in 33% of patients > 50 years(not recommended by the guideline).Adherence for proton pump inhibitors(PPIs) therapy was 80%,but doses prescribed were lower(half) in 5% of cases and higher(double) in 15%.Adherence regarding duration of PPI therapy was 69%;duration was shorter than recommended in 1%(4 wk in esophagitis grades C-D) or longer in 30%(8 wk in esophagitis grades A-B or in patients without endoscopy).Treatment response was higher when PPI doses were consistent with guidelines,although differences were not significant(95% vs 85%).CONCLUSION:GERD guideline compliance was quite good although endoscopy was over indicated in patients > 50 years without alarm symptoms;PPIs were prescribed at higher doses and longer duration.

Comparative clinical trial of S-pantoprazole versus racemic pantoprazole in the treatment of gastro-esophageal reflux disease

AIM: To compare the effi cacy and tolerability of S-pan- toprazole (20 mg once a day) versus racemic Panto- prazole (40 mg once a day) in the treatment of gastro- esophageal reflux disease (GERD). METHODS: This multi-centre, randomized, double-blind clinical trial consisted of 369 patients of either sex suf- fering from GERD. Patients were randomly assigned to receive either one tablet (20 mg) of S-pantoprazole once a day (test group) or 40 mg racemic pantoprazole once a day (reference group) for 28 d. Patients were evaluated for reduction in baseline on d 0, GERD symptom score on d 14 and 28, occurrence of any adverse effect during the course of therapy. Gastrointestinal (GI) endoscopy was performed in 54 patients enrolled at one of the study centers at baseline and on d 28. RESULTS: Signifi cant reduction in the scores (mean and median) for heart burn (P < 0.0001), acid regurgitation (P < 0.0001), bloating (P < 0.0001), nausea (P < 0.0001) and dysphagia (P < 0.001) was achieved in both groups on d 14 with further reduction on continuing the therapy till 28 d. There was a statistically signifi cant difference in the proportion of patients showing improvement in acid regurgitation and bloating on d 14 and 28 (P = 0.004 for acid regurgitation; P = 0.03 for bloating) and heart burn on d 28 (P = 0.01) between the two groups, with a higher proportion in the test group than in the refer- ence group. Absolute risk reductions for heartburn/acid regurgitation/bloating were approximately 15% on d 14 and 10% on d 28. The relative risk reductions were 26%-33% on d 14 and 15% on d 28. GI endoscopy showed no signifi cant difference in healing of esophagitis (P = 1) and gastric erosions (P = 0.27) between the two groups. None of the patients in either group reported any adverse effect during the course of therapy.CONCLUSION: In GERD, S-pantoprazole (20 mg) is more effective than racemic pantoprazole (40 mg) in improving symptoms of heartburn, acid regurgitation, bloating and equally effective in healing esophagitis and gastric erosions. The relative risk reduction is 15%-33%. Both drugs are safe and well tolerated.

Prevalence of overweightedness in patients with gastro-esophageal reflux

AIM: To evaluate whether the prevalence of overweight and obese conditions is increased in gastro-esophageal reflux disease (GERD) patients (with 24-h pathological pH recordings) in comparison to general population. METHODS: A total of 196 consecutive patients (103 females, age range 18-83 years) with symptoms of gastro-esophageal reflux (GER) and 24-h pathological esophageal pH-metry. Body mass index (BMI) of the patients was calculated and its distribution (%) was compared with that of the Italian general population as assessed by National Bureau of Census (ISTAT). To evaluate the association of GERD with weight categories, the binomial test was employed. P < 0.05 was considered statistically significant. RESULTS: In males, overweightedness (BMI 25-25.9) was present in 43% of GERD patients vs 41.8% of Italian population (IP) (ns), obesity (BMI ≥ 30) in 10.9% vs 9.1% (ns). In females overweight was present in 34.9% of GERD patients vs 25.7% of IP (P < 0.01), obesity in 13.6% of GERD patients vs 9.1% of IP (P < 0.01). No statistically significant differences were noted in different age classes. CONCLUSION: In comparison to the Italian general population, the prevalence of overweightedness and obesity is increased in female but not in male patients with ascertained gastro-esophageal reflux disease.

Test-based exclusion diets in gastro-esophageal reflux disease patients:A randomized controlled pilot trial

AIM: To investigate the clinical response of gastro-esophageal reflux disease (GERD) symptoms to exclusion diets based on food intolerance tests.

Proton pump inhibitor resistance, the real challenge in gastro-esophageal reflux disease

Gastro-esophageal reflux disease(GERD)is one of the most prevalent chronic diseases.Although proton pump inhibitors(PPIs)represent the mainstay of treatment both for healing erosive esophagitis and for symptom relief,several studies have shown that up to 40%of GERD patients reported either partial or complete lack of response of their symptoms to a standard PPI dose once daily.Several mechanisms have been proposed as involved in PPIs resistance,including ineffective control of gastric acid secretion,esophageal hypersensitivity,ultrastructural and functional changes in the esophageal epithelium.The diagnostic evaluation of a refractory GERD patients should include an accurate clinical evaluation,upper endoscopy,esophageal manometry and ambulatory pH-impedance monitoring,which allows to discriminate non-erosive reflux disease patients from those presenting esophageal hypersensitivity or functional heartburn.Treatment has been primarily based on doubling the PPI dose or switching to another PPI.Patients with proven disease,not responding to PPI twice daily,are eligible for anti-reflux surgery.

Gastro-esophageal reflux disease and obesity, where is the link?

The confluence between the increased prevalence of gastro-esophageal reflux disease(GERD)and of obesity has generated great interest in the association between these two conditions.Several studies have addressed the potential relationship between GERD and obesity,but the exact mechanism by which obesity causes reflux disease still remains to be clearly defined.A commonly suggested pathogenetic pathway is the increased abdominal pressure which relaxes the lower esophageal sphincter,thus exposing the esophageal mucosal to gastric content.Apart from the mechanical pressure,visceral fat is metabolically active and it has been strongly associated with serum levels of adipocytokines including interleukin-6 and tumor necrosis factorα,which may play a role in GERD or consequent carcinogenesis.This summary is aimed to explore the potential mechanisms responsible for the association between GERD and obesity,and to better understand the possible role of weight loss as a therapeutic approach for GERD.

Gender difference in gastro-esophageal reflux diseases

The incidence of esophageal adenocarcinoma(EAC) has risen sharply in western countries over the past 4 decades. This type of cancer is considered to follow a transitional process that goes from gastro-esophageal reflux disease(GERD) to Barrett's esophagus(BE,a metaplastic condition of the distal esophagus), a precursor lesion and ultimately adenocarcinoma. This spectrum of GERD is strongly predominant in males due to an unidentified mechanism. Several epidemiologic studies have des cribed that the prevalence of GERD, BE and EAC in women is closely related to reproductive status, which suggests a possible association with the estrogen level. Recently, we revealed in an in vivo study that the inactivation of mast cells by the anti-inflammatory function of estrogen may account for the gender difference in the GERD spectrum. Other studies have described the contribution of female steroid hormones to the gender difference in these diseases. Estrogen is reported to modulate the metabolism of fat, and obesity is a main risk factor of GERDs. Moreover, estrogen could confer esophageal epithelial resistance to causative refluxate. These functions of estrogen might explain the approximately 20-year delay in the incidence of BE and the subsequent development of EAC in women compared to men, and this effect may be responsible for the male predominance. However, some observational studies demonstrated that hormone replacement therapy exerts controversial effects in GERD patients. Nevertheless, the estrogen-related endocrine milieu may prevent disease progression toward carcinogenesis in GERD patients. The development of innovative alternatives to conventional acid suppressors may become possible by clarifying the mechanisms of estrogen.

Transoral incisionless fundoplication for gastro-esophageal reflux disease: Techniques and outcomes

Gastro-esophageal reflux disease(GERD)is a verycommon disorder that results primarily from the loss of an effective antireflux barrier,which forms a mechanical obstacle to the retrograde movement of gastric content.GERD can be currently treated by medical therapy,surgical or endoscopic transoral intervention.Medical therapy is the most common approach,though concerns have been increasingly raised in recent years about the potential side effects of continuous longterm medication,drug intolerance or unresponsiveness,and the need for high dosages for long periods to treat symptoms or prevent recurrences.Surgery too may in some cases have consequences such as longlasting dysphagia,flatulence,inability to belch or vomit,diarrhea,or functional dyspepsia related to delayed gastric emptying.In the last few years,transoral incisionless fundoplication(TIF)has proved an effective and promising therapeutic option as an alternative to medical and surgical therapy.This review describes the steps of the TIF technique,using the Esophy X&#174;device and the MUSETM system.Complications and their management are described in detail,and the recent literature regarding the outcomes is reviewed.TIF reconfigures the tissue to obtain a full-thickness gastroesophageal valve from inside the stomach,by serosato-serosa plications which include the muscle layers.To date the procedure has achieved lasting improvement of GERD symptoms(up to six years),cessation or reduction of proton pump inhibitor medication in about 75%of patients,and improvement of functional findings,measured by either p H or impedance monitoring.

Anesthetic management of the SRS^(TM) endoscopic stapling system for gastro-esophageal reflux disease

The SRS TM Endoscopic Stapling System(Medigus,Tel Aviv,Israel) is a new tool capable of creating a totally endoscopic fundoplication,combined with an endoscope,endoscopic ultrasound and a surgical stapler.SRS TM endoscopic stapling for gastro-esophageal reflux disease is a minimally invasive,outpatient procedure,which requires general anesthesia with positive-pressure ventilation.Keeping the patient on positive endexpiratory pressure(PEEP) may minimize the pressure gradient between the esophagus and the mediastinum,as well as help to prevent air from leaking around the screws and causing pneumomediastinum.In addition,in patients with hiatal hernia,higher PEEP levels may be required to increase intra-thoracic pressure and to force the stomach to slide into the abdomen for ease of endoscopy.We advise smoother emergence from anesthesia,taking precautions for retching,postoperative nausea and vomiting(PONV),while coughing and gagging during extubation and PONV may affect the success of the procedure.Total intravenous anesthesia with propofol and remifentanil seems to be a good choice for these reasons.

Symptoms of Gastro-Esophageal Reflux Disease: A Comparative Study between Elderly and Younger Patients in Japan

The difference in gastro-esophageal reflux disease (GERD) symptoms between elderly and younger GERD patients has not been fully studied. Our aim was to examine if there was any difference in the degree of GERD symptoms between elderly and younger patients with reflux esophagitis. Patients who were diagnosed by endoscopic examination as having reflux esophagitis and who answered the questionnaire on the frequency scale for the symptoms of GERD (FSSG) were included. Elderly and younger adult patients were defined as patients aged 65 and over or less than 65, respectively. 596 subjects were included. 184 subjects (mean 71.1 years;114 males) were classified into the Elderly group, and 412 subjects (mean 51.2 years;307 males) into the Younger group. The mean FSSG score of the Elderly and Younger groups was 6.7 and 8.4, respectively (p = 0.0024). Among those with severe esophagitis, the mean FSSG score of the Elderly and Younger groups was 8.5 and 8.7, respectively (p = 0.58). Although elderly patients tended to have less degree of GERD symptoms than younger patients, these findings suggest that there may be no significant age-related difference in complaints of GERD symptoms among severe reflux esophagitis patients.

Gastro-esophageal reflux disease symptoms are more common in general practice in Japan

To accurately assess the prevalence of GERD symptoms in general practice. METHODS： 4139 consecutive patients （2025 men and 2114 women with a mean age of 43 years）, who first attended the Outpatient Department of General Medicine and Emergency Care at Toho University Omori Hospital, were asked to respond to the F-scale questionnaire regardless of their chief complaints. The questionnaire is a self-report instrument, written in a simple and easy-to- understand language, containing 12 questions. RESULTS： Of 4139 subjects, 1554 patients （37.6%） were identified as GERD according to their F-scale score （〉 7）. However, there were only 45 consultations （1.1%） for typical GERD symptoms. Although GERD symptoms are common in adults of all ages, the prevalence of GERD was highest in the 20-29 years age group and the age group 70-79 years had the lowest prevalence for both males and females. CONCLUSION： Although there was a high rote indicating GERD in our primary care population, only 1.1% of outpatients attended our hospital with a chief complaint of GERD symptoms. Since about one-third of GERD patients are affected by atypical symptoms, general physicians need to be cautious about extrapolating these results to patients with a chief complaint other than typical GERD symptoms.Watanabe T, Urita Y, Sugimoto M, Miki K. Gastro-esophagea reflux disease symptoms are more common in genera practice in Japan. World J Gastroenterol 2007; 13（31） 4219-4223

Rabeprazole vs esomeprazole in non-erosive gastro-esophageal reflux disease: A randomized, double-blind study in urban Asia

AIM：Gastro-esophageal reflux disease (GERD) is becoming increasingly common in Asia. Data on the efficacy of proton pump inhibitors in patients with non-erosive GERD (NERD)in Asia is lacking. This double-blind study compared the efficacy and safety of rabeprazole with esomeprazole in relief of symptoms in patients with NERD.METHODS: One hundred and thirty-four patients with reflux symptoms of NERD and normal endoscopy were randomized to receive rabeprazole 10 mg or esomeprazole 20 mg once daily for 4 wk. Symptoms were recorded in a diary and changes in severity of symptoms noted.RESULTS: At 4 wk of treatment, rabeprazole 10 mg and esomeprazole 20 mg were comparable with regards to the primary endpoint of time to achieve 24-h symptomfree interval for heartburn 8.5 d vs9 d and regurgitation 6 d vs 7.5 d. Rabeprazole and esomeprazole were also similarly efficacious in term of patient's global evaluation with 96% of patients on rabeprazole and 87.9% of patients on esomeprazole, reporting that symptoms improved(P=NS). Satisfactory relief of day- and night-time symptoms was achieved in 98% of patients receiving rabeprazole and 81.4% of patients receiving esomeprazole. Adverse events were comparable in both groups (P = NS).CONCLUSION: Rabeprazole 10 mg has a similar efficacy and safety profile in Asians with NERD as esomeprazole 20 mg. Further study is necessary to investigate whether the small differences between the two drugs seen in this study are related to the improved pharmacodynamicpro perties of rabeprazole. Both drugs were well tolerated.

Metabolic syndrome and gastro-esophageal reflux:A link towards a growing interest in developed countries

The aim of this Editorial is to describe the growing possibility of a link between gastro-esophageal reflux disease (GERD) and metabolic syndrome on the light of recent epidemiological and pathophysiological evidence. The state of the art of GERD is described,based on recent definitions,pathophysiological evidence,epidemiology in developed countries,clinical subtypes together with a diagnostic approach specifically focussed on the appropriateness of endoscopy. Metabolic syndrome is accurately defined and the pivotal role of insulin resistance is emphasized. The strong relationship between GERD and metabolic syndrome has been pathophysiologically analyzed,taking into account the role of obesity,mechanical factors and metabolic changes. Data collected by our group regarding eating habits and GERD are briefly summarized at the end of a pathophysiological analysis. The literature on the subject strongly supports the possibility that lifestyle and eating habits may be involved in both GERD and metabolic syndrome in developed countries.

Ultrasonographic study of postcibal gastro-esophageal reflux and gastric emptying in infants with recurrent respiratory disease

AIM: To check the utility of postcibal ultrasonography for the evaluation of reflux in relation to gastric emptying in infants with recurrent respiratory symptoms and to link imaging with clinical data.METHODS: Esophageal reflux (hyperechoic retrograde filling) and gastric emptying (antral areas) were quantified before and after ingestion of a standard formula in 35 untreated infants (13 with chronic cough,22 with recurrent bronchitis) and in 31 controls.RESULTS: The prevalence of abnormal (≥8 episodes)postcibal refluxes was 74% in patients and 3% in controls. Number, duration of the longest episode and extent of refluxes were significantly higher in patients compared to controls. Number of refluxes was higher in patients with symptomatic refluxes than in those without.Infants with recurrent bronchitis had more refluxes than those with chronic cough and controls. Extent and timing of gastric emptying were similar in patients and controls.CONCLUSION: Esophageal ultrasonography is a useful and physiological test in infants with recurrent respiratory diseases, which have a high prevalence of abnormal postcibal esophageal reflux and a gastric emptying similar to that of normal controls. Esophageal reflux is more severe in subjects with recurrent bronchitis than in those with chronic cough.

Sensitivity of Esophageal Scintigraphy (Milk Scans) in Detecting Gastro-Esophageal Reflux

Gastro-esophageal scintigraphy (milk scan) is an accurate technique for detecting gastro-esophageal reflux that can be performed rapidly with minimal patient discomfort. A retrospective study was performed to find out to how much radionuclide milk scan is sensitive for detecting gastro-esophageal reflux (GER) for 89 patients who subjected to milk scan within Years 2010 to 2013. The study group age is ranging from one month old to four years old. Milk scan was performed using PHILIPS and SEIMENS machine. Tc 99-m sulfur colloid with milk administrated orally or through nasogastric tube to the patient. The highest frequency for milk scan study was in age group of 0 - 6 months old with 77% positive finding. Patients who suffer repeated vomiting represented the highest reason of examination for milk scan (46% of overall cases), while chocking attacks, pulmonary aspiration, and congenital heart disease, were 26%, 16%, 12% respectively of the overall cases. Seventy-nine percent of patients who prepared to be examine using nasogastric tube found with positive finding, 50% of GER patients have abnormal tracer activity in the mid of esophagus;on the other hand, 50% of GER patients divided equally between the lower and upper esophagus. The study show that infants especially in age of 0 - 6 months old and with repeated vomiting symptoms are strongly recommended to milk scan study rather than fluoroscopy to avoid unnecessary dose to the patients.

Perioperative and late outcomes of laparoscopic fundoplication for neurologically impaired children with gastro-esophageal reflux disease

Background Persistent gastro-esophageal reflux （GER） due to various pathological factors often results in overt clinical symptoms and signs, which is termed as gastro-esophageal reflux disease （GERD）. Affected children usually present with failure to thrive, recurrent pneumonia or apnea. Many neurologically impaired children have symptoms related to GERD. Although laparoscopic fundoplication has been established to be an effective treatment modality for children with GERD, data on its role and long-term efficacy for neurologically impaired patients remain sparse. The aim of this study was to review the results of such patients who underwent laparoscopic fundoplication.
