New Approaches to Gastroesophageal Reflux Disease

Neuromodulation and Functional Gastrointestinal Disease

INTRODUCTION

Functional gastrointestinal disorders (FGIDs) are common, and they severely impair an individual's quality of life. The mechanism of pathogenesis and the effective treatments for FGIDs remain elusive. Neuromodulation-a relatively new treatment-has exhibited a good therapeutic effect on FGIDs, although there are different methods for different symptoms of FGIDs.

MATERIALS AND METHODS

We used PubMed to review the history of neuromodulation for the treatment of FGIDs and to review several recently proposed neuromodulation approaches with improved effects on FGIDs.

CONCLUSION

Electroacupuncture, transcutaneous electroacupuncture, transcutaneous auricular vagal nerve stimulation, sacral nerve stimulation (SNS) (which relies on vagal nerve stimulation), and gastric electrical stimulation (which works through the modulation of slow waves generated by the interstitial cells of Cajal), in addition to the noninvasive neurostimulation alternative approach method of SNS-tibial nerve stimulation and transcutaneous electrical stimulation (which is still in its infancy), are some of the proposed neuromodulation approaches with improved effects on FGIDs. This review has discussed some critical issues related to the selection of stimulation parameters and the underlying mechanism and attempts to outline future research directions backed by the existing literature.

Gastroesophageal reflux management after vertical sleeve gastrectomy

VSG is the most used surgical procedure in the world. Among the main complications linked to this procedure is GERD. It is apparent that endoscopic control protocols should be undertaken in all patients recovering from a VSG procedure. This is particularly key when taking into account the large number of patients suffering from GERD that show no symptoms, a situation that in many cases leads to severe esophagitis or even adenocarcinoma. Once the pertinent diagnostic tests have been carried out, the specialist should seek a conservative medical treatment including PPI. In the event that this treatment should fail, the next step to be considered should be a surgical procedure. In this case, the ideal procedure would be a reconversion to gastric bypass due to its low-risk and its results. There are other alternatives such as the Stretta, Linx or ARMS procedures; however, further research is necessary to prove their reliability.

Laparoscopic fundoplication in treating refractory gastroesophageal reflux-related chronic cough: A meta-analysis

BACKGROUND

Gastroesophageal reflux-related chronic cough (GERC), is one common type of chronic cough. Drug treatment is effective for some GERC patients. But, there is refractory GERC (rGERC). For rGERC, fundoplication may be the only effective method. However, there were very few studies about laparoscopic fundoplication in treating rGERC, and the cure rate of fundoplication in treating rGERC was unknown. So there is a question, what is the cure rate of fundoplication in treating rGERC? To solve this question, we performed this meta-analysis.

METHODS

The PRISMA strategy and Cochrane collaboration method were used for this study. Our study was registered with PROSPERO (ID: CRD42021251072). We searched PubMed, Medline, Web of Science, and the Cochrane databases from 1990 to December 2022. The meta-analysis was performed with Review Manager 5.4 and Stata 14.

RESULTS

After selection and exclusion, 8 articles out of 672 were included. The meta-analysis showed the cure rate of laparoscopic fundoplication in treating rGERC was 62% (95% confidence interval: 53-71%), with no deaths in 503 patients. There was no significant heterogeneity or bias in the meta-analysis.

CONCLUSIONS

In terms of safety, laparoscopic fundoplication is quite reliable offered by skilled surgeons. In terms of cure rate, laparoscopic fundoplication could completely heal two-thirds of rGERC patients; however, there are still some patients who can not be completely cured by fundoplication.

Traditional Chinese medicine based on Tongjiang methodology combined with proton pump inhibitor (PPI) step-down in treating non-erosive reflux disease: a study protocol for a multicentered, randomized controlled clinical trial

BACKGROUND

Non-erosive reflux disease (NERD) is characterized by typical gastroesophageal reflux symptoms, such as heartburn and regurgitation but an absence of esophageal mucosal damage during upper gastrointestinal endoscopy. Although proton pump inhibitors (PPIs) are the first line therapy, almost 50% of patients with NERD fail to respond to this treatment. Traditional Chinese medicine (TCM) can better relieve the symptoms of NERD. Therefore, a randomized controlled trial (RCT) was designed to investigate the efficiency of TCM granules based on Tongjiang (TJ) methodology combined with PPI step-down therapy for NERD patients who did not respond to PPIs alone.

METHOD

This multicentered, double-blinded, RCT with two parallel groups will recruit 174 participants who will be randomized into the TCM granules combined with PPI step-down group (n = 87) and the TCM granules placebo combined with PPI step-down group (n = 87). Both groups of participants will receive 6 weeks of treatment and 4 weeks of follow-up, and all participants will be assessed for related symptoms, mental health status, and quality of life at each visit. The primary outcome measurements include visual analog scale (VAS) for heartburn and regurgitation and the major symptoms scale. The secondary outcome measurements include PPI withdrawal rate, symptom recurrence rate, minor symptoms scale, SF-36, PRO, SAS, SDS, GERD-HRQL, and TCM syndromes scales.

DISCUSSION

Previous research has shown that TCM is capable to alleviate NERD symptoms. This trial will help to provide a better understanding of the synergistic efficiency of the combination of TCM and PPIs, to explore whether the dosage of PPIs can be reduced after the supplement of TCM granules and to provide a feasible plan to reduce dependencies or withdraw NERD patients from PPIs. The outcome of this trial is expected to reduce the symptom recurrence rates, lessen patients' physical and psychological burdens, and achieve good social benefits.

Surgeon specialty does not influence outcomes of hiatal hernia repair

BACKGROUND

Hiatal hernia repair is commonly performed by both general and thoracic surgeons. The present study examined differences in approach, setting, and outcomes by specialty for hiatal hernia repair.

METHODS

Adults undergoing hiatal hernia repair were identified in the 2012-2019 American College of Surgeons National Surgical Quality Improvement Program. Patients were grouped by specialty of the operating surgeon (thoracic surgery vs general surgery). Generalized linear models were used to evaluate the effect of specialty on mortality, major morbidity, and 30-day readmission.

RESULTS

Among 46,739 patients, 5.0% were operated on by thoracic surgery. General surgery operated on younger patients (44.7 years vs 47.0, P < .001) with lesser systemic illness (American Society of Anesthesiologists class ≥3 50.4% vs 54.8%, P < .001) compared to thoracic surgery. General surgery more commonly used laparoscopy (95.0% vs 82.6%) and less commonly used thoracic approaches than thoracic surgery (0.6% vs 8.5%, P < .001). From 2012 to 2019, the proportion of cases performed as an outpatient by general surgery increased (28.1% to 46.4%, P < .001), but it remained stable for thoracic surgery (0.1% to 0.7%, P = .10). After risk adjustment, thoracic surgery specialty was not associated with mortality (odds ratio 0.9, 95% confidence interval 0.5-1.5), major morbidity (0.9, 95% confidence interval 0.7-1.1), or readmission (0.9, 95% confidence interval 0.8-1.1). Rather, factors including surgical approach (laparotomy 1.6, 95% confidence interval 1.4-1.9; thoracoscopy/thoracotomy 2.0, 95% confidence interval 1.5-2.7), inpatient case status (2.4, 95% confidence interval 2.2-2.7), increasing ASA class, and functional status more strongly influenced major morbidity.

CONCLUSION

Operative factors, surgical approach, and patient comorbidities more strongly influence outcomes of hiatal hernia repair than does surgeon specialty, suggesting continued safety of hiatal hernia repair by both thoracic and general surgeons.

Assessment and management of gastroesophageal reflux disease following bariatric surgery

Gastroesophageal reflux disease (GERD) is a common disease in patients with obesity. The incidence of de novo GERD and the effect of bariatric surgery on patients with pre-existing GERD remain controversial. Management of GERD following bariatric surgery is complicated and can range from medical therapy to non-invasive endoscopic options to invasive surgical options. To address these issues, we performed a systematic review of the literature on the incidence of GERD and the various modalities of managing GERD in patients following bariatric surgery. Given the increased number of laparoscopic sleeve gastrectomy (LSG) procedures being performed and the high incidence of GERD following LSG, bariatric surgeons should be familiar with the options available to manage GERD following LSG as well as other bariatric procedures.

Manual Cervical Traction and Trunk Stabilization Cause Significant Changes in Upper and Lower Esophageal Sphincter: A Randomized Trial

OBJECTIVES

Dysfunctions in the lower esophageal sphincter (LES) and the upper esophageal sphincter (UES) levels can occur owing to poor muscle coordination, contraction, or relaxation. Such condition can possibly be addressed by functional rehabilitation. The aim of this study was to measure pressure changes in the UES and LES at rest and during routine rehabilitation techniques, that is, cervical manual traction and trunk stabilization maneuver.

METHODS

This study was conducted in a University Hospital Gastrointestinal Endoscopy Center. Cervical manual traction and a trunk stabilization maneuver were performed in a convenient group of 54 adult patients with gastroesophageal reflux disease. High-resolution manometry was used to measure pressure changes in the LES and UES at rest and during manual cervical traction and trunk stabilization maneuver.

RESULTS

Average initial resting UES pressure was 90.91 mmHg. A significant decrease was identified during both cervical traction (average UES pressure = 42.13 mmHg, P < .001) and trunk stabilization maneuver (average UES pressure = 62.74 mmHg, P = .002). The average initial resting LES pressure was 14.31 mmHg. A significant increase in LES pressure was identified both during cervical traction (average LES pressure = 21.39 mmHg, P < .001) and during the trunk stabilization maneuver, (average pressure = 24.09 mmHg, P < .001).

CONCLUSION

Cervical traction and trunk stabilization maneuvers can be used to decrease pressure in the UES and increase LES pressure in patients with gastroesophageal reflux disease.

Clinical efficacy and safety of magnetic sphincter augmentation (MSA) and transoral incisionless fundoplication (TIF2) in refractory gastroesophageal reflux disease (GERD): a systematic review and meta-analysis

Background and study aims Proton pump inhibitors (PPI) are effective medical therapy options for gastro-esophageal reflux disease (GERD). However, 20 % to 40 % of patients report symptoms despite taking daily PPI. Transoral incisionless fundoplication (TIF2) and magnetic sphincter augmentation (MSA) are less invasive options for the treatment of refractory GERD and are increasingly gaining popularity.

Methods We conducted a comprehensive search of several databases to identify relevant studies. Our primary aim was to compare the efficacy of both interventions reported as improvement in Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) score, overall patient satisfaction, improvement in post-procedure regurgitation, and fraction of patients completely off PPI therapy at follow up.

Results Twenty-four studies with 1942 patients were included in the final analysis. Both MSA and TIF2 had comparable technical success and clinical success based on improvement in GERD-HRQL scores i. e. 98.8 % (CI 95.6,99.7) vs 98.5 % (CI 95.7,99.5) and 80.4 % (CI 66,89.6) vs 77.7 % (CI 64.1,87.2), respectively. A significantly greater proportion of patients reported improvement in regurgitation, i. e. 91.1 % (CI 83.8,95.3) vs 73.1 % (CI 62.5,81.7) and were able to completely discontinue PPI therapy with MSA compared to TIF2 i. e. 91.3 % (CI 81.5,96.2) vs 63.8 % (CI 51.6,74.4). Patients’ BMI and presence of a hiatal hernia did not have any effect on procedural outcomes.

Conclusion Both procedures performed at par when comparing clinical success in terms of improvement in GERD-HRQL scores. In terms of overall patient satisfaction, post procedure regurgitation and cumulative number of patients off PPI therapy, MSA outperforms TIF2.

Functional genetic variations of CYP2C19 promoter from patients with gastroesophageal reflux disease

BACKGROUND

Gastroesophageal reflux disease (GERD) is a chronic, progressive condition, and its prevalence is increasing worldwide. The risk factors for GERD are complex and the pathogenesis of GERD has not been fully elucidated. As acid-suppressive drugs, proton pump inhibitors (PPIs) are commonly used to treat GERD; after being metabolized by CYP2C19 in the human liver, the blood concentration of PPIs gradually decreases. Previous studies have shown that CYP2C19 gene polymorphism leads to considerable individual differences of PPIs in terms of metabolic rate and efficacy.

AIM

To identify potential variations in CYP2C19 promoter from patients (normal metabolizers, NMs, *1/*1) with GERD, verify the activity of promoter with variations in HEK 293T, and analyze the correlation between variations in CYP2C19 promoter and PPI treatment effect for GERD in the Chinese population.

METHODS

A total of 163 patients with sporadic GERD were collected. After diagnostic treatment with PPIs, the symptom score decreased by 50%, but the symptoms did not completely disappear in the study group (n = 82). In the control group (n = 81), the symptoms completely disappeared after treatment. The CYP2C19 genotype of all patients was detected as *1/*1. The PCR and Sanger sequencing were used to identify variations in the CYP2C19 promoter. The luciferase activities of pGL3 basic-CYP2C19 promoters with or without variation were detected by dual-luciferase assay.

RESULTS

Three novel heterozygous variations were identified in the CYP2C19 gene promoters isolated from three NM patients with GERD: g.94761364 T>A, g.94762112 T>A, and g.94762514 G>T. Compared to the wild type, the transcriptional activity of the CYP2C19 promoter with g.94761364 T>A was significantly increased (P = 0.034).

CONCLUSION

The transcriptional activity of the CYP2C19 promoter is significantly increased in the presence of g.94761364 T>A, which may further affect the metabolism and blood concentration of PPIs. This finding provides a new insight for the medication and treatment of GERD patients in the Chinese population.

Efficacy and Safety of Esomeprazole for the Treatment of Reflux Symptoms in Patients with Gastroesophageal Reflux Disease: A Systematic Review and Meta-Analysis

Background:

We investigated the efficacy of esomeprazole for the treatment of gastroesophageal reflux disease (GERD) in a meta-analysis of clinical trials results.

Methods:

Medline, Embase, PubMed and Web of Science databases were systematically searched for suitable studies, and double-blind, randomized controlled trials (RCTs) were involved. A meta-analysis of RCTs was performed to analyze the efficacy of esomeprazole on clinical outcomes that associated with the severity of GERD.

Results:

A total of 8 clinical trials were selected in our meta-analysis (N=4495, patients with GERD). Esomeprazole treatment yielded a significant improvement in clinical signs and symptoms of GERD compared to placebo group. Funnel plot and Egger test showed there was no significant bias in the publication. Cochrane collaboration tool and Jadad scale were used to indicate that all 8 RCTs were of high quality. The results of Galbraith radial plot showed that no study was the major source of heterogeneity. Esomeprazole treatment significantly decreased the relapse rates more than that of placebo group (RR = 0.729; 95% CI: 0.670 to 0.794; P<0.001). It seems to be lower rates of heartburn (RR = 0.747; 95%CI: 0.665–0.839; P <0.001) and epigastric pain (RR = 0.795; 95%CI: 0.679–0.932; P =0.005) in esomeprazole-treated group compared with the placebo group. Moreover, serious adverse events was less likely to happen after esomeprazole therapy (RR = 1.406, 95% CI: 1.030–1.918; P =0.032).

Conclusion:

Compared with the control group, esomeprazole is a promising therapeutic agent that improves the management of patients with GERD.

[Esophageal pH-impedance monitoring of reflux patterns in non-erosive reflux disease, reflux hypersensitivity and functional heartburn]

OBJECTIVE

To analyze the differences in reflux patterns in 24-hour esophageal pH-impedance monitoring in patients with non-erosive reflux disease (NERD), reflux hypersensitivity (RH) and functional heartburn (FH) and explore the possible mechanism of symptoms in patients with heartburn and negative endoscopic findings.

METHODS

Seventy-nine patients with heartburn as the main symptoms but negative endoscopic findings, including 35 with NERD, 16 with RH and 28 with FH, were enrolled in this study.All the patients underwent 24-h esophageal pH-impedance monitoring and esophagogastroscopy, and the results were compared among the 3 groups.

RESULTS

Acid reflux episode was significantly increased and weakly alkaline reflux episode was significantly decreased in NERD group in comparison with RH group and FH group (P < 0.05).The patients in NERD group showed significantly increased total reflux episode, mixed reflux episode, proximal acid reflux episode, proximal weak acid reflux episode, total proximal reflux episode, percentage of proximal acid reflux, percentage of proximal weak acid reflux, and percentage of total proximal reflux as compared with the other two groups (all P < 0.05).Bolus clear time was significantly prolonged in NERD group compared with that in the other two groups (P < 0.05).Analysis of the reflux acidity showed that the percentages of different reflux episodes differed significantly among the 3 groups (P < 0.05);acid reflux was the main reflux in NERD, while weak acid reflux was the main reflux in RH and FH groups, which had also significantly increased weakly alkaline reflux episodes compared with NERD group.

CONCLUSIONS

Patients with NERD, RH and FH had different reflux patterns.Acid reflux is predominant in the NERD, while weakly alkaline reflux is significantly increased RH and FH.In patients with normal esophageal acid exposure but without symptoms or without recorded symptoms during esophageal pH-impedance monitoring, analysis of the total reflux episode, mixed reflux episode, proximal acid reflux episode and percentage can help in the differential diagnosis between RH and FH.

Gastroesophageal reflux disease: key messages for clinicians

Gastroesophageal reflux disease (GERD) is a chronic common disorder for which patients often refer to specialists. In the last decades, numerous studies helped to clarify the pathophysiology and the natural history of this disease. Currently, in the clinical setting, GERD is defined by the presence of symptoms that, when endoscopic investigation is required, permit to distinguish between cases with or without associated esophageal mucosal injuries. These conditions are called erosive reflux disease and non-erosive reflux disease (NERD), respectively. The latter is the most common manifestation of GERD. Symptoms are defined typical, as heartburn and regurgitation, and atypical (also called extra-esophageal), as coughing and/or wheezing, hoarseness, sore throat, otitis media, and dental manifestations. In this context, it is crucial for clinicians to investigate the presence of features of suspected malignancy, as unexplained weight loss, anemia, dysphagia, persistent vomiting, familiar history of cancer, long history of GERD, and beginning of GERD symptoms after the age of 50 years. The presence of these risk factors should induce to perform an endoscopic examination. Particular attention should be given to functional conditions that can mimic GERD, such as functional heartburn and hypersensitive esophagus as well as, more rarely, eosinophilic esophagitis. The former ones have different pathophysiology and this explains the frequent non-response to proton pump inhibitor drugs. This narrative review provides to clinicians a useful and practical overview of the state-of-the-art on advancements in the knowledge of GERD.

Efficacy and safety of traditional Chinese herbal formula combined with western medicine for gastroesophageal reflux disease: A protocol for systematic review and meta-analysis

BACKGROUND

The combined therapy of Chinese herbal formula and western medicine against gastroesophageal reflux disease (GERD) could significantly improve the clinical effect, reduce the recurrence rate and the side effects of western medicine, and even reduce the dosage and course of treatment of western medicine. This study tried to systematically evaluate the efficacy and safety traditional Chinese herbal formula combined with western medicine in the treatment of GERD.

METHODS

Randomized controlled trials of traditional Chinese herbal formula combined with western medicine for GERD patients will be systematically searched using the PubMed, Embase, Medline, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang database, Chongqing VIP Chinese Science and Technology Periodical Database, and Chinese Biological and Medical database (CMB) until Aug. 28, 2020. Two researchers will perform data extraction and risk of bias assessment independently. Statistical analysis will be conducted in RevMan 5.3.

RESULTS

This study will summarize the present evidence by exploring the efficacy and safety of traditional Chinese herbal formula combined with western medicine in the treatment of GERD.

CONCLUSIONS

The findings of the study will help to determine potential benefits of traditional Chinese herbal formula combined with western medicine against GERD.

The Great ESKAPE: Exploring the Crossroads of Bile and Antibiotic Resistance in Bacterial Pathogens

Throughout the course of infection, many pathogens encounter bactericidal conditions that threaten the viability of the bacteria and impede the establishment of infection. Bile is one of the most innately bactericidal compounds present in humans, functioning to reduce the bacterial burden in the gastrointestinal tract while also aiding in digestion. It is becoming increasingly apparent that pathogens successfully resist the bactericidal conditions of bile, including bacteria that do not normally cause gastrointestinal infections. This review highlights the ability of Enterococcus, Staphylococcus, Klebsiella, Acinetobacter, Pseudomonas, Enterobacter (ESKAPE), and other enteric pathogens to resist bile and how these interactions can impact the sensitivity of bacteria to various antimicrobial agents. Given that pathogen exposure to bile is an essential component to gastrointestinal transit that cannot be avoided, understanding how bile resistance mechanisms align with antimicrobial resistance is vital to our ability to develop new, successful therapeutics in an age of widespread and increasing antimicrobial resistance.

Can Omentopexy Reduce the Incidence of Gastroesophageal Reflux Disease After Laparoscopic Sleeve Gastrectomy

BACKGROUND

De novo gastroesophageal reflux disease (GERD) is one of the complications that may occur after laparoscopic sleeve gastrectomy (LSG). This study was conducted to examine whether omentopexy can be effective in reducing the incidence of GERD after LSG.

METHODS

A total of 201 patients (145 females) were compared in this retrospective cohort study, including Group A (n = 100) and Group B (n = 101), consisting of patients undergoing LSG with omentopexy and LSG without omentopexy, respectively. One year after surgery, the patients were evaluated by GERD-Q; those obtaining a score of eight or above also underwent upper endoscopy to confirm their de novo GERD.

RESULTS

Thirty-seven patients had a GERD-Q score ≥ 8 and therefore underwent upper endoscopy. Seventeen patients had fully normal endoscopy results, and no significant differences was observed between the two groups in terms of the incidence of de novo GERD (P = 0.966). There were also no significant differences between the groups in terms of age (P = 0.517), sex (P = 0.193), diabetes (P = 0.979), and GERD-Q score (P = 0.880). The pre-operative mean weight (P = 0.003) and total weight loss (TWL) showed significant intergroup differences (P = 0.001). The mean body mass index (BMI) showed significant differences between the groups before the operation (P = 0.001) and 1 year after the surgery (P = 0.009). Excess BMI loss (EBMIL) was also significantly higher in Group A 1 year after the surgery (P = 0.004). Even after omitting confounder effect of BMI between two groups with and without omentopexy, GerdQ was not significantly different.

CONCLUSION

Omentopexy does not have a significant effect on reducing the incidence of de novo GERD after LSG, even in individuals with higher BMI and weight.

Omentopexy in Sleeve Gastrectomy Reduces Early Gastroesophageal Reflux Symptoms

INTRODUCTION

Laparoscopic sleeve gastrectomy (LSG) is one of the surgical procedures indicated in the treatment of obesity. The occurrence of gastroesophageal reflux (GER) in the postoperative period of this surgery is related to a reduction in the lower esophageal sphincter (LES) tone and the presence of gastric residual fundus (RF) associated with increased gastric intraluminal pressure. Fixation of the remaining gastric reservoir to the gastrosplenic and gastrocolic ligaments (omentopexy) has emerged as a technical option to avoid or decrease GER in the postoperative period of LSG.

OBJECTIVE

To evaluate the presence of GER symptoms, alterations in LES tone, and the presence of RF in obese subjects submitted to LSG with omentopexy.

METHODS

Twenty obese patients were submitted to LSG with omentopexy from July 2016 to July 2017 at the Hospital Unimed de Teresina, Brazil and was studied prospectively. Clinical evaluations, including a specific questionnaire (clinical score), upper digestive endoscopy and esophageal manometry, were performed preoperatively and on the 90th postoperative day. Contrast x-ray of the esophagus, stomach, and duodenum were performed after the 90th postoperative day. The Fischer exact test was used to evaluate the correlation between GER symptoms and changes in LES tone or the presence of RF. Analysis of variance was used to evaluate the correlation of GER symptoms with the 2 variables together. All analyses adopted a level of significance for α errors >5% (P-value <0.05).

RESULTS

The mean clinical score of GER reduced from 6.7 in the preoperative period to 2.7 in the postoperative period. By manometry, there were no significant changes in the LES tone with mean values of 26.04 and 27.07 mm Hg before and after the procedure. RF was identified in 3 cases by contrast radiology. There was no statistical correlation between the changes in the LES tone or the presence of RF with the increase in the clinical score of GER (in cases where this occurred), even when the variables were evaluated together.

CONCLUSIONS

LSG with omentopexy improved the clinical score of GER in most cases and did not cause significant changes in the LES tone. The presence of RF did not exacerbate the clinical score of GER.

Relationship between night reflux and sleep disturbance in elderly patients with gastroesophageal reflux disease in a tertiary hospital

BACKGROUND

The reflux symptoms of gastroesophageal reflux disease (GERD) seriously affect the quality of life of patients. Daytime reflux is obvious, but the duration of reflux is short, which has little impact on the quality of life. Although the frequency of nocturnal regurgitation is low, its duration is long, which seriously affects the sleep quality of patients. Therefore, GERD nocturnal regurgitation has become one of clinical research hotspots and an important problem to be solved.

AIM

To observe the relationship between night reflux and sleep disturbance in elderly patients with GERD in a tertiary hospital.

METHODS

Two hundred and forty elderly patients with gastroesophageal reflux admitted to the Second Jinhua Hospital of Zhejiang Province from February 2017 to August 2019 were selected as subjects for investigation of the incidence of nocturnal reflux symptoms, manifestations of sleep disorders, and the relationship between nocturnal reflux and sleep disorders.

RESULTS

Of 240 cases of GERD included, 36 (15.0%) had no nocturnal reflux and 204 (85.0%) had. In the past 1 mo, nocturnal reflux developed on average once a week or less in 34 (16.67%) of 204 patients with nocturnal reflux, twice a week in 78 (38.24%), and > 2 times in 52 (25.49%). Of 36 cases without nocturnal reflux symptoms, 9 (25.0%) had a sleep disorder, while all 204 (100.0%) cases with nocturnal reflux suffered from a sleep disorder. The incidence of sleep disorder was significantly higher in patients with nocturnal reflux than in those without (P < 0.05). Approximately 77.94% of the patients had decreased sleep quality. Daytime residual effect was found in 70.10% of patients. Sleep latency was prolonged in 55.88% of patients. When the latency was prolonged, the time to sleep was mainly 30-40 min. The total sleep time was shortened in 53.92% of patients, most of whom had a sleep time of 4-5 h. Among the 204 GERD patients, 106 (51.96%) needed drug therapy for nocturnal reflux, including 36 (33.96%) patients taking rabeprazole orally, 20 (18.87%) taking omeprazole orally, 30 (28.30%) taking cimetidine orally, and 20 (18.87%) taking sleeping pills orally, with an effective rate of 96.23% (102/106).

CONCLUSION

Nocturnal reflux may be one of the reasons affecting sleep disorders in elderly GERD patients. Proton pump inhibitor therapy can be administered in clinical practice.

Surgical Management of Gastroesophageal Reflux Disease in Patients with Severe Esophageal Dysmotility

BACKGROUND

Gastroesophageal reflux disease (GERD) and esophageal dysmotility are often disqualifying criteria for fundoplication due to dysphagia complications. A tailored partial fundoplication may improve GERD in patients with severe esophageal motility disorders. We evaluate this approach on GERD improvement in non-achalasia esophageal dysmotility patients.

METHODS

A single-institution prospective database was reviewed (2007-2016), with inclusion criteria of GERD, previous diagnosis of non-achalasia esophageal motility disorder, and laparoscopic partial fundoplication. Diagnosis of previous achalasia diagnosis or diffused esophageal spasm was excluded. Motility studies, pre- and post-upper gastrointestinal imaging (UGI), esophageal symptom scores, antacid, and PPI use were collected pre-op, 6 months, 12 months, and long-term (LT). Statistical analysis was made using SPSS v.23.0.0, α = 0.05.

RESULTS

Fifty-two patients met the inclusion criteria. A total of 17.3% had esophageal body amotility, 79.6% had severe esophageal dysmotility. A total of 65.9% women (mean age 64 ± 15.7), mean peristalsis 45.3 ± 32.6%, and failed peristalsis 36.0 ± 32.2%. Mean LES residual pressure was 15.0 ± 18.0 mmHg, and 40.7% had hypotensive LES. Mean follow-up time was 25 months [1-7 years], with significant improvement in symptoms and reduction in PPI and antacid use at all time-points compared to pre-op. A total of 74% had UGI studies at 12 months; all showed persistent dysmotility. Six patients had radiographic hiatal hernia recurrence, with only one being clinically symptomatic postoperatively. Three required dilation for persistent dysphagia.

CONCLUSIONS

A tailored partial fundoplication may be effective in symptom relief for non-achalasia patients with esophageal motility disorders and GERD. Significant symptom improvement, low HHR, and PPI use clearly indicate this approach to be effective for this population.

SHORT-TERM RESULTS OF MINIMALLY INVASIVE TREATMENT OF GASTROESOPHAGEAL REFLUX DISEASE BY RADIOFREQUENCY (STRETTA): FIRST BRAZILIAN SERIES OF CASES

BACKGROUND

New endoscopic treatments for gastroesophageal reflux (GERD) are developed every year and are indicated in cases that are refractory to conventional therapies as well as after surgical treatment failure.

OBJECTIVE

To present the first cases of endoscopic therapy for GERD performed in Brazil.

METHODS

Use of radiofrequency with the Stretta procedure in symptomatic volunteers diagnosed with GERD.

RESULTS

The technique was performed in three patients after they were included in the study protocol. No patient had complications, and all patients were discharged on the same day, either without medication or taking it sporadically for symptom control.

CONCLUSION

Endoscopic treatment for GERD using radiofrequency was effective in the cases presented herein with no technical complications.

Long-term reported outcomes of transoral incisionless fundoplication: an 8-year cohort study

BACKGROUND

Transoral incisionless fundoplication (TIF) offers an endoscopic approach to the treatment of gastroesophageal reflux disease (GERD). Controlled trials have demonstrated the short-term efficacy of this procedure, but long-term follow-up studies are lacking. The objective of this study was to evaluate the long-term impact of TIF on disease-specific quality of life and antisecretory medication use.

METHODS

We performed retrospective cohort study of all patients undergoing TIF between 2007 and 2014 in a large academic medical center. Reflux symptoms and quality of life were assessed using the gastroesophageal reflux disease health-related quality of life (GERD-HRQL) questionnaire at baseline, short-term, and long-term follow-up.

RESULTS

Fifty-seven patients with a median age of 46 (37-59) years and an average BMI of 28.8 ± 4.9 kg/m² underwent TIF during the study period. Sixty percent of the patients were female, and all were taking a PPI at least daily. At a median follow-up interval of 97 months, twelve patients had undergone subsequent laparoscopic antireflux surgery (LARS). Of those who had not, 23 had complete long-term follow-up data for analysis and were included in the study. Seventy-three percent reported daily acid-reducing medication use, and the median GERD-HRQL score was 10 (6-14) compared to 24 (15-28) at baseline (p < 0.01). Seventy-eight percent of these patients expressed satisfaction or neutral feelings about their GERD management. There were no significant differences in the baseline characteristics of patients who underwent LARS during the study period and those who did not.

CONCLUSIONS

This study demonstrates that TIF can produce durable improvements in disease-specific quality of life in some patients with symptomatic GERD. The majority of patients resumed daily PPI therapy during the study period, but with significantly improved GERD-HRQL scores compared to baseline and increased satisfaction with their medical condition.

Overview of treatment of gastroesophageal reflux disease by traditional Chinese medicine and Western medicine

In recent years, traditional Chinese medicine and Western medicine have made some progress in the treatment of gastroesophageal reflux disease. Through literature retrieval, this paper reviews the relevant literature on gastroesophageal reflux disease in recent three years and summarizes the current situation of treatment of gastroesophageal reflux disease by traditional Chinese medicine and Western medicine. In order to seek a more extensive and effective treatment for gastroesophageal reflux disease, this paper also puts forward our own viw and prospect on the treatment of this disease.
