Long-term symptom control of gastro-oesophageal reflux disease 12 years after laparoscopic Nissen or 180° anterior partial fundoplication in a randomized clinical trial

Antireflux surgeries and hiatal repair: keys to success

INTRODUCTION

Gastroesophageal reflux is common, and when medical therapy is ineffective, alternative treatments should be considered. Nissen fundoplication controls reflux but can be followed by side effects such as dysphagia and flatulence. To improve outcomes, modifications have been advocated.

AREAS COVERED

Modifications to Nissen fundoplication and newer procedures for gastroesophageal reflux aim to improve overall outcome. Randomized controlled trials (RCTs) and long-term outcomes from large cohorts are prioritized to consider the optimal procedure for reflux and hiatus hernia.

EXPERT OPINION

Fundoplication is an effective treatment for gastroesophageal reflux, with success rates of >80% reported at 18-20-year follow-up. RCTs confirm that Nissen fundoplication delivers better reflux control than medication. However, some patients are troubled by side effects. Anterior and posterior partial fundoplication variants have been proposed as procedures that offer equally good reflux control, but fewer side effects, and RCTs have confirmed this with follow-up to 20 years. Which partial fundoplication is better is debated. Alternative laparoscopic or endoscopic approaches require expensive implants or equipment and deliver less reliable reflux control than partial fundoplication. Currently, level I evidence confirms that laparoscopic partial fundoplication delivers the optimal outcome in fit patients with reflux that is not well controlled by medication.

Systematic review of the perioperative classification, diagnosis, description and repair of hiatus hernias in randomized controlled trials

Hiatus hernias (HH) are a common cause of symptoms and complications, with considerable variation in anatomy, function, diagnosis and treatment. We undertook the first systematic review to appraise how HH are diagnosed and classified in the literature, using randomized controlled trials as a sample. A search was performed in July 2021of the PubMed, EMBASE and Cochrane Central Register of Controlled Trials, and 2832 articles were identified and 64 were included. Median Jadad score was 2. Studies demonstrated considerable variation in diagnosis, classification and minimum surgical steps. The commonest classifications before surgery were axial length and the Type I-IV classification, variably assessed by endoscopy and contrast swallow. Intra-operatively, the commonest classification was type I-IV. A minority used more than one classification, or alternatives such as defect size and Hill classification. Most studies reported minimum steps, but these varied. Only a minority reported criteria for diagnosing recurrence. Using randomized controlled trials to appraise the highest quality evidence in the literature, we found considerable variation and inconsistency in the way HH are diagnosed and classified. This lack of a 'common language' has significant impacts for the generalizability of evidence, study synthesis and design. We propose the development of an internationally accepted classification. We wish to confirm that there are no known conflicts of interest associated with this publication and there has been no significant financial support for this work that could have influenced its outcome. We confirm that the manuscript has been read and approved by all named authors and that there are no other persons who satisfied the criteria for authorship but are not listed. We further confirm that the order of authors listed in the manuscript has been approved by all of us.

Laparoscopic floppy Nissen fundoplication with valve calibration: a safe and efficient procedure

PURPOSES

A floppy Nissen fundoplication with valve calibration (FNF-VC) performed by laparotomy has been described, to reduce postoperative dysphagia and gas bloating after 360°-fundoplication. As laparoscopy is the gold standard for fundoplication, this study reports the first results of a modified FNF-VC adapted for laparoscopy (LFNF).

METHODS

Seventy-two consecutive patients, who underwent LFNF for refractory GERD between 2012 and 2021, were included. Postoperative outcomes and quality of life (QoL) by GERSS, GERD-HRQL, and GIQLI scores before and after surgery were assessed.

RESULTS

The main symptoms were pyrosis (81%), regurgitation (39%), Ear-Nose-Throat symptoms (22%), and thoracic pain (24%). Hiatal hernia was present in 85% (n = 61) of the patients. There was no postoperative mortality, and the severe postoperative morbidity rate (Dindo-Clavien ≥ III) was 6%. After a median follow-up of 3.6 years, only 8% of patients were still taking proton-pump inhibitors. Long-term residual dysphagia was noted in 15% of the patients, but none required reoperation or interventional endoscopic procedures. QoL improved, with a significant reduction in GERSS and GERD-HRQL scores and a postoperative GIQLI of 101.75 (75-117.5).

CONCLUSION

This series reports the safety and efficacy of an FNF-VC adapted for laparoscopy to treat GERD with a limited rate of residual dysphagia.

Long-term outcomes following Dor, Toupet, and Nissen fundoplication: a network meta-analysis of randomized controlled trials

BACKGROUND

In the surgical management of GERD, the traditional procedure is laparoscopic total (Nissen) fundoplication. However, partial fundoplication has been advocated as providing similar reflux control while potentially minimizing dysphagia. The comparative outcomes of different approaches to fundoplication are a topic of ongoing debate and long-term outcomes remain uncertain. This study aims to compare long-term gastroesophageal reflux disease (GERD) related outcomes following different fundoplication procedures.

METHODS

MEDLINE, EMBASE, PubMed, and CENTRAL databases were searched up to November 2022 to identify randomized controlled trials (RCTs) comparing different types of fundoplications reporting long-term (> 5 years) outcomes. The primary outcome was incidence of dysphagia. Secondary outcomes included incidence of heartburn/reflux, regurgitation, inability to belch, abdominal bloating, reoperation, and patient satisfaction. DataParty, which uses Python 3.8.10 was used to perform the network meta-analysis. We evaluated the overall certainty of evidence with the GRADE framework.

RESULTS

13 RCTs were included, with 2063 patients across Nissen (360°), Dor (anterior 180°-200°), and Toupet (posterior 270°) fundoplications. Network estimates demonstrated that Toupet had lower incidence of dysphagia compared to Nissen (OR 0.285; 95% CrI 0.06-0.958). There were no differences in dysphagia between Toupet and Dor (OR 0.473, 95% CrI 0.072-2.835) or between Dor and Nissen (OR 1.689, 95% CrI 0.403-7.699). The three fundoplication types were comparable in all other outcomes.

CONCLUSIONS

All three approaches of fundoplication share similar long-term outcomes, with the Toupet fundoplication likely providing the best long-term durability with lowest odds of developing postoperative dysphagia.

Multi-society consensus conference and guideline on the treatment of gastroesophageal reflux disease (GERD)

BACKGROUND

Gastroesophageal reflux disease (GERD) is one of the most common diseases in North America and globally. The aim of this guideline is to provide evidence-based recommendations regarding the most utilized and available endoscopic and surgical treatments for GERD.

METHODS

Systematic literature reviews were conducted for 4 key questions regarding the surgical and endoscopic treatments for GERD in adults: preoperative evaluation, endoscopic vs surgical or medical treatment, complete vs partial fundoplication, and treatment for obesity (body mass index [BMI] ≥ 35 kg/m2) and concomitant GERD. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Recommendations for future research were also proposed.

RESULTS

The consensus provided 13 recommendations. Through the development of these evidence-based recommendations, an algorithm was proposed for aid in the treatment of GERD. Patients with typical symptoms should undergo upper endoscopy, manometry, and pH-testing; additional testing may be required for patients with atypical or extra-esophageal symptoms. Patients with normal or abnormal findings on manometry should consider undergoing partial fundoplication. Magnetic sphincter augmentation or fundoplication are appropriate surgical procedures for adults with GERD. For patients who wish to avoid surgery, the Stretta procedure and transoral incisionless fundoplication (TIF 2.0) were found to have better outcomes than proton pump inhibitors alone. Patients with concomitant obesity were recommended to undergo either gastric bypass or fundoplication, although patients with severe comorbid disease or BMI > 50 should undergo Roux-en-Y gastric bypass for the additional benefits that follow weight loss.

CONCLUSION

Using the recommendations an algorithm was developed by this panel, so that physicians may better counsel their patients with GERD. There are certain patient factors that have been excluded from included studies/trials, and so these recommendations should not replace surgeon-patient decision making. Engaging in the identified research areas may improve future care for GERD patients.

Current management of gastro-oesophageal reflux disease-treatment costs, safety profile, and effectiveness: a narrative review

Background

The purpose of this study was to review the current management of gastro-oesophageal reflux disease (GORD), including treatment costs, safety profile and effectiveness.

Methods

A literature review was performed of randomized-controlled trials, systematic reviews, Cochrane reports and National/Societal guidelines of the medical, endoscopic and surgical management of GORD. Proton pump inhibitor (PPI) prescribing patterns and expenditure were reviewed in different countries, including Australia, Canada, New Zealand, UK and USA.

Results

Proton pump inhibitors (PPIs) are primarily indicated for control of GORD, Helicobacter pylori eradication (combined with antibiotics), preventing NSAID-induced gastrointestinal bleeding and treating peptic ulcer disease. There is widespread overprescribing of PPIs in Western and Eastern nations in terms of indication and duration, with substantial expense for national health providers. Despite a favourable short-term safety profile, there are observational associations of adverse effects with long-term PPIs. These include nutrient malabsorption, enteric infections and cardiovascular events. The prevalence of PPI use makes their long-term safety profile clinically relevant. Cost-benefit, symptom control and quality-of-life outcomes favour laparoscopic fundoplication rather than chronic PPI treatment. Laparoscopic fundoplication in long-term management of PPI-responsive GORD is supported by SAGES, NICE and ACG, and PPI-refractory GORD by AGA and SAGES guidelines. The importance of establishing a definitive diagnosis prior to invasive management is emphasized, especially in PPI-refractory heartburn.

Conclusions

We examined evidence-based guidelines for PPI prescribing and deprescribing in primary care and hospital settings and the need for PPI stewardship and education of health professionals. This narrative review presents the advantages and disadvantages of surgical, endoscopic and medical management of GORD, which may assist in shared decision making and treatment choice in individual patients.This paper was presented (GS020) at the 88th RACS Annual Scientific Conference, 6-10 May, 2019.

UEG and EAES rapid guideline: Update systematic review, network meta-analysis, CINeMA and GRADE assessment, and evidence-informed European recommendations on surgical management of GERD

BACKGROUND

There are several options for the surgical management of GERD in adults. Previous guidelines and systematic reviews have compared the effects of total fundoplication versus pooled effects of different techniques of partial fundoplication.

OBJECTIVE

To develop evidence-informed, trustworthy, pertinent recommendations on the use of total, posterior partial and anterior partial fundoplications for the management of GERD in adults.

METHODS

We performed an update systematic review, network meta-analysis, and evidence appraisal using the GRADE and the Confidence in Network Meta-Analysis methodologies. An international, multidisciplinary panel of surgeons, gastroenterologists, and a patient representative reached unanimous consensus through an evidence-to-decision framework to select among multiple interventions, and a Delphi process to formulate the recommendation. The project was developed in an online authoring and publication platform (MAGICapp), and was overseen by an external auditor.

RESULTS

We suggest posterior partial fundoplication over total posterior or anterior 90° fundoplication in adult patients with GERD. We suggest anterior >90° fundoplication as an alternative, although relevant comparative evidence is limited (weak recommendation). The guideline, with recommendations, evidence summaries and decision aids in user friendly formats can also be accessed in MAGICapp: https://app.magicapp.org/#/guideline/j20X4n.

CONCLUSION

This rapid guideline was developed in line with highest methodological standards and provides evidence-informed recommendations on the surgical management of GERD. It provides user-friendly decision aids to inform healthcare professionals' and patients' decision making.

Randomized Trial of Laparoscopic Nissen Versus Anterior 180 Degree Partial Fundoplication - Late Clinical Outcomes at 15 to 20 years

OBJECTIVE

To determine very late clinical outcomes at up to 20 years follow-up from a randomized controlled trial of Nissen versus anterior 180-degree partial fundoplication.

SUMMARY BACKGROUND DATA

Nissen fundoplication for gastroesophageal reflux can be followed by troublesome side effects. To address this, partial fundoplications have been proposed. Previously reports from a randomized controlled trial of Nissen versus anterior 180-degree partial fundoplication at up to 10 years follow-up showed good outcomes for both procedures.

METHODS

One hundred seven participants were randomized to Nissen versus anterior 180-degree partial fundoplication. Fifteen to 20 year follow-up data was available for 79 (41 Nissen, 38 anterior). Outcome was assessed using a standardized questionnaire with 0 to 10 analog scores and yes/no questions to determine reflux symptoms, side-effects, and satisfaction with surgery.

RESULTS

After anterior fundoplication heartburn (mean score 3.2 vs 1.4, P = .001) and proton pump inhibitor use (41.7% vs 17.1%, P = .023) were higher, offset by less dysphagia for solids (mean score 1.8 vs 3.3, P = .015), and better ability to belch (84.2% vs 65.9%, P = .030). Measures of overall outcome were similar for both groups (mean satisfaction score 8.4 vs 8.0, P = .444; 86.8% vs 90.2% satisfied with outcome). Six participants underwent revision after anterior fundoplication (Nissen conversion for reflux - 6), and 7 underwent revision after Nissen fundoplication (Nissen to partial fundoplication for dysphagia - 5; redo Nissen for reflux - 1; paraesophageal hernia -1).

CONCLUSIONS

At 15 to 20 years follow-up Nissen and anterior 180-degree partial fundoplication achieved similar success, but with trade-offs between better reflux control versus more side-effects after Nissen fundoplication.

Surgical treatment of GERD: systematic review and meta-analysis

BACKGROUND

Gastroesophageal reflux disease (GERD) has a high worldwide prevalence in adults and children. There is uncertainty regarding medical versus surgical therapy and different surgical techniques. This review assessed outcomes of antireflux surgery versus medical management of GERD in adults and children, robotic versus laparoscopic fundoplication, complete versus partial fundoplication, and minimal versus maximal dissection in pediatric patients.

METHODS

PubMed, Embase, and Cochrane databases were searched (2004-2019) to identify randomized control and non-randomized comparative studies. Two independent reviewers screened for eligibility. Random effects meta-analysis was performed on comparative data. Study quality was assessed using the Cochrane Risk of Bias and Newcastle Ottawa Scale.

RESULTS

From 1473 records, 105 studies were included. Most had high or uncertain risk of bias. Analysis demonstrated that anti-reflux surgery was associated with superior short-term quality of life compared to PPI (Std mean difference =  - 0.51, 95%CI  - 0.63, - 0.40, I² = 0%) however short-term symptom control was not significantly superior (RR = 0.75, 95%CI 0.47, 1.21, I² = 82%). A proportion of patients undergoing operative treatment continue PPI treatment (28%). Robotic and laparoscopic fundoplication outcomes were similar. Compared to total fundoplication, partial fundoplication was associated with higher rates of prolonged PPI usage (RR = 2.06, 95%CI 1.08, 3.94, I² = 45%). There was no statistically significant difference for long-term symptom control (RR = 0.94, 95%CI 0.85, 1.04, I² = 53%) or long-term dysphagia (RR = 0.73, 95%CI 0.52, 1.02, I² = 0%). Ien, minimal dissection during fundoplication was associated with lower reoperation rates than maximal dissection (RR = 0.21, 95%CI 0.06, 0.67).

CONCLUSIONS

The available evidence regarding the optimal treatment of GERD often suffers from high risk of bias. Additional high-quality randomized control trials may further inform surgical decision making in the treatment of GERD.

Complete vs partial fundoplication: a laboratory measurement of functionality and effectiveness

BACKGROUND

Complete or partial fundoplication remains controversial for the surgical treatment of GERD. While partial fundoplication is considered less effective, it is associated with less post-operative dysphagia and gas bloating compared with complete fundoplication.

AIM

To compare the mechanical efficiency of the three different types of fundoplication.

MATERIAL AND METHOD

Two studies of the LES were performed on explanted stomachs: distensibility and failure point. Measurements were taken before and after fundoplication.

RESULTS

There was no difference in distensibility between Nissen and Toupet fundoplication, however, the EGJ was more distensible following Dor fundoplication. According to failure point measurements, Nissen fundoplication was significantly more effective than Toupet, Toupet was significantly more effective than Dor (p = .016, p = .017, respectively).

CONCLUSIONS

There were significant differences in distensibility between Dor and both Nissen and Toupet, however no statistical difference between Toupet and Nissen. There was a significant difference in effectiveness between all three types of fundoplication according to the failure point. These laboratory findings demonstrate that the mechanical orientation of Nissen and Toupet have similar functionality suggesting that Toupet is as good as Nissen. While in clinical studies Toupet has fewer post-operative complications these findings support the proponents of Toupet for GERD. Abbreviation: GERD: Gastroesophageal reflux disease.

[Current aspects of surgical treatment of gastro-esophageal reflux disease]

Gastroesophageal reflux disease (GERD) is characterized by abnormal reflux of gastric content into the esophagus, pharynx, respiratory tract and oral cavity. In recent years, there has been a significant increase of the incidence of this disease, that significantly aggravates quality of life of the population. The 'gold standard' for treating GERD is anti-secretory therapy with proton pump inhibitors (PPIs). However, up to 40% of patients are unresponsive to PPIs even after dose adjustment. Advantages and disadvantages of modern surgical approaches for this pathology are reviewed. Laparoscopic fundoplication including Nissen (360°), Toupet (270°) and Dor procedures (180°) is the most common anti-reflux operation. In addition, new alternative surgical options are also discussed. For example, these are minimally invasive methods such as LINX reflux control system, electrical stimulation of the lower esophageal sphincter and transoral incisionless fundoplication (TIF). These methods are less aggressive and have less side effects. A comparative assessment of modern methods of surgical treatment of GERD is made.

Comparison of Laparoscopic 270° Posterior Partial Fundoplication vs Total Fundoplication for the Treatment of Gastroesophageal Reflux Disease: A Randomized Clinical Trial

Importance

Restoration of the esophagogastric junction competence is critical for effective long-term treatment of gastroesophageal reflux disease. Surgical repair results in such restoration, but mechanical adverse effects seem unavoidable. Minimizing these adverse effects without jeopardizing reflux control is warranted.

Objective

To determine whether partial fundoplication (PF) or total fundoplication (TF) is superior in laparoscopic antireflux surgery.

Design, Setting, and Participants

In this double-blind, randomized clinical trial of 1171 patients scheduled for laparoscopic antireflux surgery at a single university-affiliated center between November 19, 2001, and January 24, 2006, 456 patients were randomized and followed up for 5 years. Data were collected from November 2001 to April 2012, and data were analyzed from April 2012 to September 2018.

Interventions

A 270° posterior PF or a 360° Nissen TF.

Main Outcomes and Measures

Esophageal acid exposure at 3 years after surgery.

Result

Of the 456 randomized patients, 268 (58.8%) were male, and the mean (SD) age was 49.0 (11.7) years. A total of 229 patients were randomized to PF, and 227 patients were randomized to TF. At 3 years postoperatively, the median (interquartile range) esophageal acid exposure was reduced from 14.6% (9.8-21.9) to 1.8% (0.7-4.4) after PF and from 16.0% (10.4-22.7) to 2.5% (0.8-6.8) after TF (P = .31). Likewise, reflux symptoms were equally and effectively controlled. Early postoperative dysphagia (6 weeks) was common in both groups but then decreased toward normality. A small but statistically significant difference in favor of PF was noted in the mean (SD) scoring of dysphagia for liquids at 6 weeks (PF, 1.6 [0.9]; TF, 1.9 [1.3]; P = .01) and for solid food at 12 months (PF, 1.3 [1.0]; TF, 1.9 [1.4]; P < .001) and 24 months (PF, 1.3 [0.9]; TF, 1.7 [1.2]; P = .001). Quality of life was reduced before surgery but increased to normal values after surgery and remained so over 5-year follow-up, with no difference between the groups.

Conclusions and Relevance

The results from this randomized clinical trial suggest that although PF and TF could be recommended for treatment of gastroesophageal reflux disease, PF might be superior by inducing less dysphagia.

Assessing the efficacy and safety of laparoscopic antireflux procedures for the management of gastroesophageal reflux disease: a systematic review with network meta-analysis

BACKGROUND

Despite the extensive literature on laparoscopic antireflux surgery, comparative evidence across different procedures is scarce. The aim of this study was to assess and rank the most efficacious and safe laparoscopic procedures for the management of gastroesophageal reflux disease.

METHODS

Medline, Embase, AMED, CINAHL, CENTRAL, and OpenGrey databases were queried for randomized trials comparing two or more laparoscopic antireflux procedures with each other or with medical treatment for the management of gastroesophageal reflux disease. Pairwise meta-analyses were conducted for each pair of interventions using a random-effects model. Network meta-analysis was employed to assess the relative efficacy and safety of laparoscopic antireflux procedures for the management of gastroesophageal reflux disease.

RESULTS

Forty-four publications reporting 29 randomized trials which included 1892 patients were identified. The network of treatments was sparse with only a closed loop between different types of wraps; 270°, 360°, anterior 180° and anterior 90°; and star network between 360° and other treatments; and between anterior 180° and other treatments. Laparoscopic 270° (odds ratio, OR 1.19, 95% confidence interval, CI 0.64-2.22), anterior 180°, and anterior 90° were equally effective as 360° for control of heartburn, although this finding was supported by low quality of evidence according to GRADE modification for NMA. The odds for dysphagia were lower after 270° (OR 0.38, 95%, CI 0.24-0.60), anterior 90° (moderate quality evidence), and anterior 180° (low-quality evidence) compared to 360°. The odds for gas-bloat were lower after 270° (OR 0.51, 95% CI 0.27, 0.95) and after anterior 90° compared to 360° (low-quality evidence). Regurgitation, morbidity, and reoperation were similar across treatments, albeit these were associated with very low-quality evidence.

CONCLUSION

Laparoscopic 270° fundoplication achieves a better outcome than 360° total fundoplication, especially in terms of postoperative dysphagia, although other types of partial fundoplication might be equally effective.

Long-term follow-up of two randomized trials comparing laparoscopic Nissen 360° with anterior 90° partial fundoplication

BACKGROUND

The side-effects of Nissen fundoplication have led to modifications, including partial fundoplications such as an anterior 90° wrap. Five-year follow-up of two randomized trials suggested fewer side-effects following anterior 90° partial fundoplication, but better reflux control after Nissen fundoplication. However, longer-term outcomes have not been reported. This study combined data from previous trials to determine 10-year outcomes.

METHODS

From 1999 to 2003, 191 patients were enrolled in two randomized trials comparing anterior 90° partial versus Nissen fundoplication. Trial protocols were similar, and data were combined to determine long-term clinical outcomes. Patients completed annual questionnaires assessing dysphagia, heartburn, medications, satisfaction and other symptoms. Visual analogue scales (0-10), a composite dysphagia score (0-45) and yes/no responses were used.

RESULTS

Of the 191 patients, 152 (79·6 per cent) were available for 10-year follow-up. After anterior 90° fundoplication, patients reported less dysphagia to solids (score 2·03 versus 3·18 for the Nissen procedure; P = 0·037). Heartburn scores were lower after Nissen fundoplication (1·90 versus 2·83 for anterior 90° fundoplication; P = 0·035) and fewer patients required proton pump inhibitors (PPIs) (22 versus 39 per cent respectively; P = 0·035). Satisfaction scores were similar for both anterior 90° and Nissen groups (7·45 versus 7·36 respectively; P = 0·566), and the majority considered their original decision for surgery to be correct (86 versus 84 per cent; P = 0·818).

CONCLUSION

After 10 years, both procedures achieved similar success as measured by global satisfaction measures. Patients who had a Nissen fundoplication reported more dysphagia, whereas more heartburn and PPI consumption were reported after anterior 90° fundoplication.

Evidence-Based Practice Guideline for Surgical Treatment of Gastroesophageal Reflux Disease 2018

The prevalence of gastroesophageal reflux disease (GERD) is increasing in Korea, and physicians, including surgeons, have been focusing on its treatment. Indeed, in Korea, medical treatment using a proton pump inhibitor is the mainstream treatment for GERD, while awareness of surgical treatment is limited. Accordingly, to promote the understanding of surgical treatment for GERD, the Korean Anti-Reflux Surgery Study Group published the Evidence-Based Practice Guideline for the Surgical Treatment of GERD. The guideline consists of 2 sections: fundamental information such as the definition, symptoms, and diagnostic tools of GERD and a recommendation statement about its surgical treatment. The recommendations presented 5 debates regarding fundoplication: 1) comparison of the effectiveness of medical and surgical treatments, 2) effectiveness of surgical treatment in cases of refractory GERD, 3) effectiveness of surgical treatment of extraesophageal symptoms, 4) comparison of effectiveness between total and partial fundoplication, and 5) effectiveness of fundoplication in cases of hiatal hernia. The present guideline is the first to demonstrate the efficacy of the surgical treatment GERD in Korea.

Surgical results of laparoscopic Toupet fundoplication for gastroesophageal reflux disease with special reference to recurrence

BACKGROUND

Surgical results of GERD have mainly been reported from the Western countries, with a few reports found in Japan. We examined the surgical results of laparoscopic Toupet fundoplication and clarify the characteristics of recurrent cases.

METHODS

The subjects included 375 patients who underwent laparoscopic Toupet fundoplication from June 1997 to December 2016 as the initial surgery. Patient characteristics, pathophysiology, and surgical results were examined. In addition, we compared the patient characteristics and pathophysiology of recurrent cases in comparison with non-recurrent cases.

RESULTS

Age 59 (43-70) and male 211 (56.3%). The operation time was 141 min (113-180) and intraoperative complications were found to have onset in 13 subjects (3.5%). Dysphagia after surgery was found in 18 cases (4.8%). The A factor (the degree of hiatal hernia), P factor (the degree of esophagitis), and pH < 4 holding time significantly improved after surgery compared with prior to surgery (p < 0.001 for all), while the LES lengths and abdominal LES lengths were extended (p < 0.001 for each). Recurrence was found in 48 patients (15.1%) among the 318 patients for whom we could confirm the presence or absence of recurrence. The A factor, P factor, and pH < 4 holding time prior to surgery were, respectively, higher in the recurrence group (p = 0.031, p < 0.001, p < 0.001).

CONCLUSIONS

Laparoscopic Toupet fundoplication for GERD could be performed safely, with a response rate as good as 85%. Compared with non-recurrent cases, preoperative clinical conditions such as esophageal hiatal hernia, reflux esophagitis, and acid reflux time were all advanced in recurrent cases.

Management of failure after surgery for gastro-esophageal reflux disease

Surgical treatment of gastro-esophageal reflux disease (ST-GERD) is well-codified and offers an alternative to long-term medical treatment with a better efficacy for short and long-term outcomes. However, failure of ST-GERD is observed in 2-20% of patients; management is challenging and not standardized. The aim of this study is to analyze the causes of failure and to provide a treatment algorithm. The clinical aspects of ST-GERD failure are variable including persistent reflux, dysphagia or permanent discomfort leading to an important degradation of the quality of life. A morphological and functional pre-therapeutic evaluation is necessary to: (i) determine whether the symptoms are due to recurrence of reflux or to an error in initial indication and (ii) to understand the cause of the failure. The most frequent causes of failure of ST-GERD include errors in the initial indication, which often only need medical treatment, and surgical technical errors, for which surgical redo surgery can be difficult. Multidisciplinary management is necessary in order to offer the best-adapted treatment.
