Management of Patients With Refractory Reflux-Like Symptoms Despite Proton Pump Inhibitor Therapy: Evidence-Based Consensus Statements

BACKGROUND

Many patients diagnosed with gastro-oesophageal reflux disease (GERD) have persistent symptoms despite proton pump inhibitor (PPI) therapy.

AIMS

The aim of this consensus is to provide evidence-based statements to guide clinicians caring for patients with refractory reflux-like symptoms (rRLS) or refractory GERD.

METHODS

This consensus was developed by the International Working Group for the Classification of Oesophagitis. The steering committee developed specific PICO questions pertaining to the management of PPI rRLS. Methodologists conducted systematic reviews of the literature. The quality of evidence and strength of recommendations were rated using the GRADE approach.

RESULTS

Consensus was reached on 13 of 17 statements on diagnosis and management. For rRLS, suggested diagnostic strategies included endoscopy, ambulatory reflux testing and oesophageal manometry. The group did not reach consensus on the role of oesophageal biopsies or the use of reflux-symptom association in patients undergoing reflux testing. The group suggested against increasing the PPI dose in patients who had received 8 weeks of a twice-daily PPI. Adjunctive alginate or antacid therapy was suggested. There was no consensus on the role of adjunctive prokinetics. There was little role for adjunctive transient lower oesophageal sphincter relaxation (TLESR) inhibitors or bile acid sequestrants. Endoscopic or surgical anti-reflux procedures should not be performed in patients with rRLS in the absence of objectively confirmed GERD.

CONCLUSIONS

The management of rRLS should be personalised, based on shared decision-making regarding the role of diagnostic testing to confirm or rule out GERD as a basis for treatment optimisation. Anti-reflux procedures should not be performed without objective confirmation of GERD.

ESNM/ANMS consensus paper: Diagnosis and management of refractory gastro-esophageal reflux disease

Up to 40% of patients with symptoms suspicious of gastroesophageal reflux disease (GERD) do not respond completely to proton pump inhibitor (PPI) therapy. The term "refractory GERD" has been used loosely in the literature. A distinction should be made between refractory symptoms (ie, symptoms may or may not be GERD-related), refractory GERD symptoms (ie, persisting symptoms in patients with proven GERD, regardless of relationship to ongoing reflux), and refractory GERD (ie, objective evidence of GERD despite adequate medical management). The present ESNM/ANMS consensus paper proposes use the term "refractory GERD symptoms" only in patients with persisting symptoms and previously proven GERD by either endoscopy or esophageal pH monitoring. Even in this context, symptoms may or may not be reflux related. Objective evaluation, including endoscopy and esophageal physiologic testing, is requisite to provide insights into mechanisms of symptom generation and evidence of true refractory GERD. Some patients may have true ongoing refractory acid or weakly acidic reflux despite PPIs, while others have no evidence of ongoing reflux, and yet others have functional esophageal disorders (overlapping with proven GERD confirmed off therapy). In this context, attention should also be paid to supragastric belching and rumination syndrome, which may be important contributors to refractory symptoms.

Surgical Treatment for Laryngopharyngeal Reflux Disease: A Systematic Review

IMPORTANCE

Laryngopharyngeal reflux (LPR) is a prevalent disease that is usually treated with diet, lifestyle modifications, and proton pump inhibitor therapy. However, nearly 10% to 30% of patients do not achieve adequate acid suppression even with high doses of proton pump inhibitors. For these patients with resistant disease, fundoplication may be recommended but the success rate of fundoplication surgery on laryngopharyngeal symptoms and findings remains uncertain.

OBJECTIVE

To determine whether fundoplication is associated with control of signs and symptoms in patients with LPR.

EVIDENCE REVIEW

A literature search was conducted on PubMed, Cochrane Library, and Scopus according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline to identify studies published between 1990 and 2018 about the efficacy of fundoplication on clinical outcomes of LPR. Three investigators screened publications for eligibility and exclusion based on predetermined criteria. Study design, patient characteristics, diagnostic method, exclusion criteria, treatment characteristics, follow-up, and quality of the outcome assessment were evaluated.

FINDINGS

Of the 266 studies identified, 34 met the inclusion criteria, accounting for 2190 patients with LPR (1270 women and 920 men; mean [SD] age at the time of surgery, 49.3 [6.3] years). A weighted mean of 83.0% of patients (95% CI, 79.7%-86.3%) experienced improvement and a weighted mean of 67.0% of patients (95% CI, 64.1%-69.9%) experienced a disappearance of symptoms, but there is a high level of methodological heterogeneity among studies according to diagnostic method, exclusion criteria, and outcomes used to assess the efficacy of fundoplication. A pH study without impedance study was used in most studies but with various inclusion criteria. According to results of an a priori assessment, the clinical outcomes used were overall poor, excluding many symptoms and findings associated with LPR.

CONCLUSION AND RELEVANCE

The reported studies of fundoplication in LPR disease have important heterogeneity in method of diagnosis, exclusion criteria, symptoms, and signs assessed as therapeutic outcomes; therefore, this systematic review was nonconclusive regarding whether surgery for LPR disease is associated with effective control of sight and symptoms. Otolaryngologists, gastroenterologists, and surgeons must establish a diagnostic criterion standard, clear indications for surgery, and future clinical outcomes to precisely assess the effectiveness of treatment.

Pre-operative clinical and instrumental factors as antireflux surgery outcome predictors

Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. Many patients with mild reflux symptoms are treated adequately with lifestyle modifications, dietary changes, and low-dose proton pump inhibitors (PPIs). For those with refractory GERD poorly controlled with daily PPIs, numerous treatment options exist. Fundoplication is currently the most commonly performed antireflux operation for management of GERD. Outcomes described in current literature following laparoscopic fundoplication indicate that it is highly effective for treatment of GERD; early clinical studies demonstrate relief of symptoms in approximately 85%-90% of patients. However it is still unclear which factors, clinical or instrumental, are able to predict a good outcome after surgery. Virtually all demographic, esophagogastric junction anatomic conditions, as well as instrumental (such as presence of esophagitis at endoscopy, or motility patterns determined by esophageal high resolution manometry or reflux patterns determined by means of pH/impedance-pH monitoring) and clinical features (such as typical or atypical symptoms presence) of patients undergoing laparoscopic fundoplication for GERD can be factors associated with symptomatic relief. With this in mind, we sought to review studies that identified the factors that predict outcome after laparoscopic total fundoplication.

Esophagogastric junction morphology assessment by high resolution manometry in obese patients candidate to bariatric surgery

INTRODUCTION

Obesity is a strong independent risk factor of gastroesophageal reflux disease (GERD) symptoms and hiatal hernia development. Pure restrictive bariatric surgery should not be indicated in case of hiatal hernia and GERD. However it is unclear what is the real incidence of disruption of esophagogastric junction (EGJ) in patients candidate to bariatric surgery. Actually, high resolution manometry (HRM) can provide accurate information about EGJ morphology. Aim of this study was to describe the EGJ morphology determined by HRM in obese patients candidate to bariatric surgery and to verify if different EGJ morphologies are associated to GERD-related symptoms presence.

METHODS

All patients underwent a standardized questionnaire for symptom presence and severity, upper endoscopy, high resolution manometry (HRM). EGJ was classified as: Type I, no separation between the lower esophageal sphincter (LES) and crural diaphragm (CD); Type II, minimal separation (>1 and < 2 cm); Type III, >2 cm separation.

RESULTS

One hundred thirty-eight obese (BMI>35) subjects were studied. Ninety-eight obese patients referred at least one GERD-related symptom, whereas 40 subjects were symptom-free. According to HRM features, EGJ Type I morphology was documented in 51 (36.9%) patients, Type II in 48 (34.8%) and Type III in 39 (28.3%). EGJ Type III subjects were more frequently associated to Symptoms than EGJ Type I (38/39, 97.4%, vs. 21/59, 41.1% p < 0.001).

CONCLUSIONS

Obese subjects candidate to bariatric surgery have a high risk of disruption of EGJ morphology. In particular, obese patients with hiatal hernia often refer pre-operative presence of GERD symptoms. Testing obese patients with HRM before undergoing bariatric surgery, especially for restrictive procedures, can be useful for assessing presence of hiatal hernia.

Effects of omega-loop bypass on esophagogastric junction function

BACKGROUND

At present, no objective data are available on the effect of omega-loop gastric bypass (OGB) on gastroesophageal junction and reflux.

OBJECTIVES

To evaluate the possible effects of OGB on esophageal motor function and a possible increase in gastroesophageal reflux.

SETTING

University Hospital, Italy; Public Hospital, Italy.

METHODS

Patients underwent clinical assessment for reflux symptoms, and endoscopy plus high-resolution impedance manometry (HRiM) and 24-hour pH-impedance monitoring (MII-pH) before and 1 year after OGB. A group of obese patients who underwent sleeve gastrectomy (SG) were included as the control population.

RESULTS

Fifteen OGB patients were included in the study. After surgery, none of the patients reported de novo heartburn or regurgitation. At endoscopic follow-up 1 year after surgery, esophagitis was absent in all patients and no biliary gastritis or presence of bile was recorded. Manometric features and patterns did not vary significantly after surgery, whereas intragastric pressures (IGP) and gastroesophageal pressure gradient (GEPG) statistically diminished (from a median of 15 to 9.5, P<.01, and from 10.3 to 6.4, P<.01, respectively) after OGB. In contrast, SG induced a significant elevation in both parameters (from a median of 14.8 to 18.8, P<.01, and from 10.1 to 13.1, P<.01, respectively). A dramatic decrease in the number of reflux events (from a median of 41 to 7; P<.01) was observed after OGB, whereas in patients who underwent SG a significant increase in esophageal acid exposure and number of reflux episodes (from a median of 33 to 53; P<.01) was noted.

CONCLUSIONS

In contrast to SG, OGB did not compromise the gastroesophageal junction function and did not increase gastroesophageal reflux, which was explained by the lack of increased IGP and in GEPG as assessed by HRiM.

Long term quality of life after laparoscopic antireflux surgery for the elderly

BACKGROUND

Studies have previously shown laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients. The aim of the current study was to evaluate patients receiving laparoscopic antireflux surgery before and after 65 years of age and to assess their surgical outcomes and improvements in long term quality of life.

METHODS

Patients were given a standardized symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication.

RESULTS

Forty-nine patients older than 65 years of age were defined as the elderly group (EG) whereas the remaining 262 younger than 65 years of age were defined as the young group (YG).

CONCLUSIONS

In conclusion, laparoscopic total fundoplication is a safe and effective surgical treatment for gastroesophageal reflux disease generally warranting low morbidity and mortality rates and a significant improvement of symptoms comparable. An improved long-term quality of life is warranted even in the elderly.

Gastroesophageal reflux disease and obesity: do we need to perform reflux testing in all candidates to bariatric surgery?

INTRODUCTION

Obesity is a strong independent risk factor of gastroesophageal reflux disease (GERD) symptoms and esophageal erosions. However the relationship between obesity and GERD is still a subject of debate. In fact, if in most cases bariatric surgery can diminish reflux by losing a large amount of fat, on the other hand some restrictive procedure can worsen or cause the presence of GERD. Thus, it is unclear if patients candidate to bariatric surgery have to perform pre-operative reflux testing or not.

AIM

of the study was to verify the presence of GERD patterns in patients candidate to surgery and the need of pre-operative reflux testing.

METHODS

All patients underwent to a standardized questionnaire for symptoms severity (GERQ), upper endoscopy, high resolution manometry (HRiM) and impedance pH-monitoring (MII-pH). Patients were stratified into: group 1 (negative for both GERQ and endoscopy), group 2 (positive for GERQ and negative for endoscopy), group 3 (positive for both GERQ and endoscopy). A healthy-volunteers group (HV) was assessed.

RESULTS

One hundred thirty-nine subjects (obese, 124; HV normal weight, 15) were studied. Group 1 showed comparable mean LES pressure, peristaltic function, bolus transport and presence of hiatal hernia than HV. Group 2 showed a reduction of these parameters, while group 3 showed a statistical significant reduction in LES pressure, peristaltic function, bolus transport and increase in presence of hiatal hernia. At MII-pH, Group 1 showed a not significant increase in reflux patterns; group 2 and 3 showed a significant increase in esophageal acid exposure and in number of refluxes (both acid and weakly acid), with group 3 showing the higher grade of reflux pattern.

CONCLUSIONS

Obese subjects with pre-operative presence of GERD symptoms and endoscopical signs could be tested with HRM and MII-pH before undergoing bariatric surgery, especially for restrictive procedures. On the other hand, obese patients without any sign of GERD could not be tested for reflux, showing similar patterns to HV.

Is the advanced age a contraindication to GERD laparoscopic surgery? Results of a long term follow-up

Background

In this prospective non randomized observational cohort study we have evaluated the influence of age on outcome of laparoscopic total fundoplication for GERD.

Methods

Six hundred and twenty consecutive patients underwent total laparoscopic fundoplication for GERD. Five hundred and twenty-four patients were younger than 65 years (YG), and 96 patients were 65 years or older (EG). The following parameters were considered in the preoperative and postoperative evaluation: presence, duration, and severity of GERD symptoms, presence of a hiatal hernia, manometric and 24 hour pH-monitoring data, duration of operation, incidence of complications and length of hospital stay.

Results

Elderly patients more often had atypical symptoms of GERD and at manometric evaluation had a higher rate of impaired esophageal peristalsis in comparison with younger patients. The duration of the operation was similar between the two groups. The incidence of intraoperative and postoperative complications was low and the difference was not statistically significant between the two groups. An excellent outcome was observed in 93.0% of young patients and in 88.9% of elderly patients (p = NS).

Conclusions

Laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients, warranting low morbidity and mortality rates and a significant improvement of symptoms comparable to younger patients.

Long term quality of life after laparoscopic antireflux surgery for the elderly

Background

Studies have previously shown laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients. The aim of the current study was to evaluate patients receiving laparoscopic antireflux surgery before and after 65 years of age and to assess their surgical outcomes and improvements in long term quality of life.

Methods

Patients were given a standardized symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication.

Results

Forty-nine patients older than 65 years of age were defined as the elderly group (EG) whereas the remaining 262 younger than 65 years of age were defined as the young group (YG).

There were 114 (36.6%) patients who filled out the SF36 questionnaire (98 in the younger group, rate: 37.4%; 16 in the elderly group, rate: 32.6%) pre- and post-operatively. There was no significant difference between the two age groups regarding preoperative PCS ( 45.6 ± 7.8 in YG vs. 44.2 ± 8.2 in EG; P = 0.51) and MCS ( 48.1 ± 10.7 in YG vs. 46.9 ± 9.2 in EG; P = 0.67). There was no significant difference between the two age groups regarding postoperative PCS (49.8 ± 11.9 in YG and 48.2 ± 9.5 in EG ; P = 0.61 and MCS (48.4 ± 10.7 in YG vs. 50.1 ± 6.9 in EG; P = 0.54).

Conclusions

In conclusion, laparoscopic total fundoplication is a safe and effective surgical treatment for gastroesophageal reflux disease generally warranting low morbidity and mortality rates and a significant improvement of symptoms comparable. An improved long-term quality of life is warranted even in the elderly.

Axillary lymphadenectomy for breast cancer in elderly patients and fibrin glue

BACKGROUND

Axillary lymphadenectomy or sentinel biopsy is integral part of breast cancer treatment, yet seroma formation occurs in 15-85% of cases. Among methods employed to reduce seroma magnitude and duration, fibrin glue has been proposed in numerous studies with controversial results.

METHODS

Thirty patients over 60 years underwent quadrantectomy or mastectomy with level I/II axillary lymphadenectomy; a suction drain was fitted in all patients. Fibrin glue spray were applied to the axillary fossa in 15 patients; the other 15 patients were treated with harmonic scalpel.

RESULTS

Suction drainage was removed between post-operative Days 3 and 4. Seroma magnitude and duration were not significant in patients receiving fibrin glue compared with the harmonic scalpel group.

CONCLUSIONS

Use of fibrin glue does not always prevent seroma formation, but can reduce seroma magnitude, duration and necessary evacuative punctures.
