Long-term comparative outcome between laparoscopic total Nissen and Toupet fundoplication: Symptomatic relief, patient satisfaction and quality of life

Could "Low Quality of Life" Rather Than "Significant Symptoms" Be Better Criteria for the Selection of Patients for the Repair of a Giant Hiatus Hernia?

Purpose Giant hiatus hernia (GHH) repair is undertaken electively in symptomatic patients, to prevent complications such as gastric volvulus and subsequent mortality. Advances in laparoscopy and perioperative care have reduced the risk of GHH repair, and improvement in quality of life (QoL) has become an important outcome measure. In our unit, we have been assessing QoL in all the operated as well as non-operated patients with GHH, using the "Quality of Life in Reflux and Dyspepsia" (QOLRAD) questionnaire. We sought to evaluate differences in QoL between patients who were managed conservatively for GHH and those who underwent GHH repair over a two-year period. Methods All patients seen in the Upper Gastrointestinal Tertiary Unit in Lancashire Teaching Hospitals NHS Trust with GHH between January 2015 and December 2022 were identified from a prospectively kept database. QOLRAD scores were analyzed and compared between conservatively and operatively managed patients using the Mann-Whitney U test. Demographic and operative outcome data were also collected. Results Eighty-seven patients with GHH were included. QoL of 51 patients improved significantly after elective surgery. Five out of 36 patients, who were initially treated conservatively, elected to have repair during their follow-up period. These 5 Patients had a lower initial QOLRAD score in comparison to those whose management remained conservative (2.72 vs 5.05, Mann Whitney U test p=0.034), and their QOLRAD scores also improved significantly after the operation. QOLRAD scores in conservatively managed patients remained stable over a two-year follow-up period. Conclusion Objectively calculated low QoL may be a more useful tool than subjective symptoms in selecting patients for elective repair of GHH.

Nissen Versus Toupet Fundoplication For Gastro-oesophageal Reflux Disease, Short And Long-term Outcomes. A Systematic Review And Meta-analysis

BACKGROUND

Gastroesophageal reflux disease (GERD) remains one of the most commonly encountered gastrointestinal disorders. Proton pump inhibitors still show an inadequate effect on about 10% to 40% of the patients. Laparoscopic antireflux surgery is the surgical alternative for managing GERD in patients who are not responding to proton pump inhibitors.

AIM OF THE STUDY

This study objected at comparing laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication (LTF) concerning the short-term and long-term outcomes.

PATIENTS AND METHODS

This is a systematic review and meta-analysis that evaluated the studies comparing between Nissen fundoplication and LTF for the treatment of GERD. Studies were obtained by searching on the EMBASE, the Cochrane Central Register of Controlled Trials, and PubMed central database.

RESULTS

The LTF group showed significantly longer operation time, less postoperative dysphagia and gas bloating, less pressure on the lower esophageal sphincter, and higher Demeester scores. No statistically significant differences were found between the 2 groups in the perioperative complications, the recurrence of GERD, the reoperation rate, the quality of life, or the reoperation rate.

CONCLUSION

LTF is favored for the surgical treatment of GERD being of lower postoperative dysphagia and gas bloating rates. These benefits were not at the expense of significantly additional perioperative complications or surgery failure.

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.

Outcomes after anti-reflux procedures: Nissen, Toupet, magnetic sphincter augmentation or anti-reflux mucosectomy?

BACKGROUND

Surgical treatment options of gastroesophageal reflux disease have changed significantly in the last 50 years. Magnetic Sphincter Augmentation (MSA) and Anti-reflux Mucosectomy (ARMs) are gaining traction but there is a paucity of literature comparing these novel options to Toupet fundoplication and gold standard Nissen fundoplication.

METHODS

This is a retrospective review of a prospectively maintained database, evaluating patients undergoing Nissen, Toupet, MSA, and ARMs. Pre-operative, intra-operative, and post-operative variables including Reflux symptom index (RSI), Gastroesophageal Reflux Disease-Health Related Quality of Life questionnaire (GERD-HRQL), and Dysphagia scores were compared between groups.

RESULTS

During the study period, 649 patients underwent anti-reflux surgery. Patients who underwent Nissen or Toupet were younger than those undergoing MSA or ARMs (65 ± 12 and 67 ± 14 years vs 56 ± 14 and 56 ± 18 years, P < 0.01). Average operative time for Nissen was 127 ± 40 min which was similar to a Toupet at 122 ± 32 min. These durations were significantly longer than for MSA, averaging 79 ± 29, and ARMs, at a mean 35 ± 3 min (all P < 0.001). Length of stay was significantly different among all four groups with Nissen, Toupet, MSA, and ARMs patients staying a median of 31, 24, 7, and 3 h post operatively, respectively (all P < 0.001). Complications and re-admissions were similarly low among all groups. Despite minor differences in RSI and GERD-HRQL scores at isolated follow-up time points, quality of life scores seems to be similar overall at up to 5 years follow-up. Gas bloat and dysphagia did not differ among groups at any time point.

CONCLUSIONS

Novel anti-reflux surgery options provide similar GERD-related quality of life compared to traditional full or partial fundoplications with the added benefit of shorter operative time and faster recovery.

Randomized controlled trial of robotic-assisted versus conventional laparoscopic fundoplication: 12 years follow-up

Aims

Numerous reports have addressed the feasibility and safety of robotic-assisted (RALF) and conventional laparoscopic fundoplication (CLF). Long-term follow-up after direct comparison of these two minimally invasive approaches is scarce. The aim of the present study was to assess long-term disease-specific symptoms and quality of life (QOL) in patients with gastroesophageal reflux disease (GERD) treated with RALF or CLF after 12 years in the randomized ROLAF trial.

Methods

In the ROLAF trial 40 patients with GERD were randomized to RALF (n = 20) or CLF (n = 20) between August 2004 and December 2005. At 12 years after surgery, all patients were invited to complete the standardized Gastrointestinal Symptom Rating Scale (GSRS) and the Quality of Life in Reflux and Dyspepsia questionnaire (QOLRAD). Failure of treatment was assessed according to Lundell score.

Results

The GSRS score was similar for RALF (n = 15) and CLF (n = 15) at 12 years´ follow-up (2.1 ± 0.7 vs. 2.2 ± 1.3, p = 0.740). There was no difference in QOLRAD score (RALF 6.4 ± 1.2; CLF 6.4 ± 1.5, p = 0.656) and the QOLRAD score sub items. Long-term failure of treatment according to the definition by Lundell was not different between RALF and CLF [46% (6/13) vs. 33% (4/12), p = 0.806].

Conclusion

In accordance with previous short-term outcome studies, the long-term results 12 years after surgery showed no difference between RALF and CLF regarding postoperative symptoms, QOL and failure of treatment. Relief of symptoms and patient satisfaction were high after both procedures on the long-term. Registration number: DRKS00014690 (https://www.drks.de).

Patient Satisfaction after Laparoscopic Nissen Fundoplication-Long-Term Outcomes of Single-Center Study

Up to 33% of the population suffers from gastroesophageal reflux disease (GERD). Given its high prevalence, the negative impact on quality of life, and the possible progression to esophageal cancer, the definitive treatment of GERD should be used more frequently. This study aims to assess long-term patient satisfaction after laparoscopic Nissen fundoplication (LNF). We reviewed the prospectively collected data of patients who underwent LNF for GERD in our department in 2014–2018. Each patient completed a preoperative questionnaire according to GERD Impact Scale (GERD-IS). Postoperative survey consisted of GERD-IS, the need for PPIs, and two “yes or no” questions to assess satisfaction with the outcome. The mean follow-up time was 50 months (21.2–76.3 ± 16.6 months). There was a statistically significant improvement in each GERD-IS question (p < 0.001). A total of 87 patients (78.4%) would recommend the surgery to their relatives. Patients without symptom recurrence and without the need for chronic PPI use after surgery were significantly more likely to recommend surgery and to undergo the procedure again (p < 001). The age of patients did not influence patients’ recommendations (p = 0.75). A total of 17 patients (15.3%) would not undergo LNF again. There was no significant correlation between the answer and patient’s complications or age (p > 0.05). LNF is a good treatment for GERD with a satisfaction rate of 78.4%.

Long-term patient satisfaction and durability of laparoscopic anti-reflux surgery in a large Danish cohort: study protocol for a retrospective cohort study with development of a novel scoring system for patient selection

INTRODUCTION

Laparoscopic anti-reflux surgery is standard of care in surgical treatment of gastro-oesophageal reflux disease and is not without risks of adverse effects, including disruption of the fundoplication and postfundoplication dysphagia, in some cases leading to reoperation. Non-surgical factors such as pre-existing anxiety or depression influence postoperative satisfaction and symptom relief. Previous studies have focused on a short-term follow-up or only certain aspects of disease, such as reoperation or postoperative quality of life. The aim of this study is to evaluate long-term patient-satisfaction and durability of laparoscopic anti-reflux surgery in a large Danish cohort using a comprehensive multimodal follow-up, and to develop a clinically applicable scoring system usable in selecting patients for anti-reflux surgery.

METHODS AND ANALYSIS

The study is a retrospective cohort study utilising data from patient records and follow-up with patient-reported quality of life as well as registry-based data. The study population consists of all adult patients having undergone laparoscopic anti-reflux surgery at The Department of Surgery, Kolding Hospital, a part of Lillebaelt Hospital Denmark in an 11-year period. From electronic records; patient characteristics, preoperative endoscopic findings, reflux disease characteristics and details on type of surgery, will be identified. Disease-specific quality of life and dysphagia will be collected from a patient-reported follow-up. From Danish national registries, data on comorbidity, reoperative surgery, use of pharmacological anti-reflux treatment, mortality and socioeconomic factors will be included. Primary outcome of this study is treatment success at follow-up.

ETHICS AND DISSEMINATION

Study approval has been obtained from The Danish Patient Safety Agency, The Danish Health Data Authority and Statistics Denmark, complying to Danish and EU legislation. Inclusion in the study will require informed consent from participating subjects. The results of the study will be published in peer-reviewed medical journals regardless of whether these are positive, negative or inconclusive.

A Modified Technique to Create a Standardized Floppy Nissen Fundoplication Without a Bougie

INTRODUCTION

Nissen fundoplication is frequently applied in the surgical treatment of patients with gastroesophageal reflux disease (GERD). When the gastroesophageal junction remains too large or becomes too narrow, persistent GERD or dysphagia may occur. To assure a correct size of the gastroesophageal junction, the fundoplication can be created over a bougie. However, this increases the risk of esophageal perforation. Therefore, we have modified a previously described technique to create a standardized fundoplication without the use of a bougie. In this article, we describe this technique and demonstrate the initial results.

MATERIALS AND METHODS

We describe a technique to create a standardized Nissen fundoplication. After suture repair of the hiatal hernia, three marking sutures were placed on the gastric fundus, based on an equilateral triangle. The size of this triangle determines the final diameter of the fundoplication. With these measurements, we assure sufficient patency, minimize rotation, and create a more reproducible fundoplication that may reduce postoperative dysphagia.

RESULTS

We have operated 15 patients according to this technique. Mean operative time was 69.5 (SD 8.4) minutes, no complications occurred. There was no early dysphagia and the mean length of stay was 1.3 days (1-2). Quality of life after 1 year was excellent.

CONCLUSIONS

This modified method for standardized Nissen fundoplication is safe and might reduce postoperative dysphagia. Quality of life after 1 year is excellent. The effect on postoperative dysphagia and the reproducibility of this technique should be established in a large prospective study.

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

BACKGROUND

Laparoscopic 180° anterior fundoplication has been shown to achieve similar reflux control to Nissen fundoplication, with fewer side-effects, up to 5 years. However, there is a paucity of long-term follow-up data on this technique and antireflux surgery in general. This study reports 12-year outcomes of a double-blind RCT comparing laparoscopic Nissen versus 180° laparoscopic anterior fundoplication for gastro-oesophageal reflux disease (GORD).

METHODS

Patients with proven GORD were randomized to laparoscopic Nissen or 180° anterior fundoplication. The 12-year outcome measures included reflux control, dysphagia, gas-related symptoms and patient satisfaction. Measures included scores on a visual analogue scale, a validated Dakkak score for dysphagia and Visick scores.

RESULTS

Of the initial 163 patients randomized (Nissen 84, anterior 79), 90 (55·2 per cent) completed 12-year follow-up (Nissen 52, anterior 38). There were no differences in heartburn, dysphagia, gas-related symptoms, patient satisfaction or surgical reintervention rate. Use of acid-suppressing drugs was less common after Nissen than after 180° anterior fundoplication: four of 52 (8 per cent) and 11 of 38 (29 per cent) respectively (P = 0·008). The proportion of patients with absent or only mild symptoms was slightly higher after Nissen fundoplication: 45 of 50 (90 per cent) versus 28 of 38 (74 per cent) (P = 0·044).

CONCLUSION

The two surgical procedures provided similar control of heartburn and post-fundoplication symptoms, with similar patient satisfaction and reoperation rates on long-term follow-up.

Would you have laparoscopic Nissen fundoplication again? A patient satisfaction survey in a UK population

OBJECTIVE

Laparoscopic Nissen fundoplication (LNF) effectively reduces objective gastro-oesophageal reflux. It can however cause side effects which affect quality of life or fail to improve subjective reflux symptoms. This study aims to assess patient satisfaction following LNF by assessing whether patients would have the procedure again.

DESIGN

Telephone survey using a structured questionnaire. Participation was voluntary.

SETTING

UK Foundation Trust (two university hospitals).

PATIENTS

All patients who had LNF performed by a single surgeon between November 2008 and June 2012.

MAIN OUTCOME MEASURES

Primarily, current reflux symptoms, antiacid medication requirement and whether participants would choose to have the procedure again (should they still have their initial symptoms). Further measures were conversion to open procedure, need for redo or reversal, and mortality.

RESULTS

99 patients underwent LNF in the quoted period; 71 were contactable and willing to participate. Of the 99, two required redo operations (neither of whom was contactable), and one had a reversal (primary operation included). Median time since the operation was 33 months (range 5-48 months). Compared with preoperatively, 72% rated their current reflux-symptom severity as ≤2/10, 23% as 3-6/10 and 4% as 7-10/10. 75% were not taking any antiacid medication. 89% of patients said that they would have the procedure again.

CONCLUSIONS

This study provides supporting evidence that LNF improves reflux symptoms and decreases medication use at intermediate-term follow-up. These results will aid counselling and reassurance of patients regarding the risks and benefits of LNF as the majority of postoperative patients were sufficiently satisfied to choose the operation again.

EAES recommendations for the management of gastroesophageal reflux disease

BACKGROUND

Gastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett's esophagus, and enteroesophageal and duodenogastroesophageal reflux.

METHODS

The European Association of Endoscopic Surgery (EAES) has tasked a group of experts, based on their clinical and scientific expertise in the field of GERD, to establish current guidelines in a consensus development conference. The expert panel was constituted in May 2012 and met in September 2012 and January 2013, followed by a Delphi process. Critical appraisal of the literature was accomplished. All articles were reviewed and classified according to the hierarchy of level of evidence and summarized in statements and recommendations, which were presented to the scientific community during the EAES yearly conference in a plenary session in Vienna 2013. A second Delphi process followed discussion in the plenary session.

RESULTS

Recommendations for pathophysiologic and epidemiologic considerations, symptom evaluation, diagnostic workup, medical therapy, and surgical therapy are presented. Diagnostic evaluation and adequate selection of patients are the most important features for success of the current management of GERD. Laparoscopic fundoplication is the most important therapeutic technique for the success of surgical therapy of GERD.

CONCLUSIONS

Since the background of GERD is multifactorial, the management of this disease requires a complex approach in diagnostic workup as well as for medical and surgical treatment. Laparoscopic fundoplication in well-selected patients is a successful therapeutic option.

Outcome following management of dysphagia after laparoscopic anti-reflux surgery

BACKGROUND

Some patients develop troublesome dysphagia after laparoscopic antireflux surgery, and a proportion require further intervention. The management of this problem was evaluated.

METHODS

Patients who underwent intervention for dysphagia after laparoscopic fundoplication were identified from a database. Outcomes were prospectively determined from a standardized questionnaire that evaluated symptoms scores for dysphagia for solids and liquids, as well as patient satisfaction with the overall outcome. Outcomes 1 year after reintervention, and at the most recent follow-up were evaluated.

RESULTS

From 1994 to 2009, 121 (6.6%) of 1,821 patients who underwent laparoscopic fundoplication for gastroesophageal reflux also underwent endoscopic or surgical reintervention for dysphagia. Of these 121 patients, 56 underwent endoscopic dilatation, and 24 were satisfied with the outcome of dilatation; 18 progressed to surgery, and dysphagia persisted in 14 of them. Overall, 83 patients underwent revisional surgery, and 47 (62.7%) were satisfied with the outcome. Compared to patients who did not undergo any intervention for dysphagia, patients who underwent reintervention had lower satisfaction scores and higher dysphagia scores.

CONCLUSIONS

Approximately two thirds of patients with troublesome post-fundoplication dysphagia have a satisfactory outcome following either endoscopic dilatation or revisional surgery. However, approximately one third continue to be troubled by symptoms, despite further intervention.

A prospective nonrandomized comparison of laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication in Indian population using detailed objective and subjective criteria

BACKGROUND:

Laparoscopic Nissen fundoplication (LNF) is a commonly performed procedure for the treatment of gastro esophageal reflux disease (GERD) worldwide. However, unfavourable postoperative sequel, including gas bloat and dysphagia, has encouraged surgeons to perform alternative procedures such as laparoscopic Toupet fundoplication (LTF). This prospective nonrandomized study was designed to compare LNF with LTF in patients with GERD.

MATERIALS AND METHODS:

Hundred and ten patients symptomatic for GERD were included in the study after having received intensive acid suppression therapy for a minimum of 8 weeks. A 24-hour pH metry was done on all patients. Fifty patients having reflux on 24-hour pH metry were taken up for the surgery. Patients were further divided into group-A (LNF) and group-B (LTF).

RESULTS:

The median percentage time with esophageal pH < 4 decreased from 10.18% and 12.31% preoperatively to 0.85% and 1.94% postoperatively in LNF and LTF-groups, respectively. There was a significant and comparable increase in length of lower esophageal sphincter (LES), length of intraabdominal part of LES and LES pressure at respiratory inversion point in both the groups. In LNF-group, five patients had early dysphagia that improved afterwards. There were no significant postoperative complications.

CONCLUSION:

LNF and LTF are highly effective in the management of GERD with significant improvement in symptoms and objective parameters. LNF may be associated with significantly higher incidence of short onset transient dysphagia that improves with time. Patients in both the groups showed excellent symptom and objective control on 24-hour pH metry on short term follow-up.

Update on fundoplication for the treatment of GERD

Rudolph Nissen firstly implemented the idea of surgical treatment of gastroesophageal reflux more than 55 years ago. Today, laparoscopic fundoplication has become the surgical "golden standard" for the treatment of GERD. However, the initial enthusiasm and increasing number of performed procedures in the early 1990s declined dramatically between 2000 and 2006. Despite its excellent outcome, laparoscopic fundoplication is only offered to a minority of patients who are suffering from GERD. In this article we review the current indications for antireflux surgery, technical and intraoperative aspects of fundoplication, perioperative complications as well as short and long-term outcome. The focus is on the laparoscopic approach as the current surgical procedure of choice.

Reflux and sex: what drives testing, what drives treatment?

Gastroesophageal reflux (GER) affects ∼10-20% of American adults. Although symptoms are equally common in men and women, we hypothesized that sex influences diagnostic and therapeutic approaches in patients with GER. PubMed database between 1997 and October 2011 was searched for English language studies describing symptoms, consultative visits, endoscopic findings, use and results of ambulatory pH study, and surgical therapy for GER. Using data from Nationwide Inpatient Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, we determined the sex distribution for admissions and reflux surgery between 1997 and 2008. Studies on symptoms or consultative visits did not show sex-specific differences. Even though women are less likely to have esophagitis or Barrett's esophagus, endoscopic studies enrolled as many women as men, and women were more likely to undergo ambulatory pH studies with a female predominance in studies from the US. Surgical GER treatment is more commonly performed in men. However, studies from the US showed an equal sex distribution, with Nationwide Inpatient Sample data demonstrating an increase in women who accounted for 63% of the annual fundoplications in 2008. Despite less common or severe mucosal disease, women are more likely to undergo invasive diagnostic testing. In the US, women are also more likely to undergo antireflux surgery. These results suggest that healthcare-seeking behavior and socioeconomic factors rather than the biology of disease influence the clinical approaches to reflux disease.

Postoperative dysphagia is not predictive of long-term failure after laparoscopic antireflux surgery

INTRODUCTION

Dysphagia is a common postoperative symptom after laparoscopic antireflux surgery, usually attributed to postoperative edema or a "too tight" fundoplication. Although it is usually self-limited, it occasionally requires endoscopic dilation and rarely revisionary surgery. It has not been previously described whether postoperative dysphagia is associated with poorer long-term reflux control after fundoplication.

METHODS

We hypothesized that the presence of dysphagia in the early postoperative period is associated with long-term failure of the antireflux procedure and recurrence of gastroesophageal reflux disease (GERD) symptoms. A retrospective review of a prospectively maintained database of patients undergoing antireflux surgery was performed. The study population included patients, who underwent primary laparoscopic Nissen fundoplication between the years 1991 and 2010. The presence of dysphagia on their first postoperative visit (<30 days) was used to classify them in the early-dysphagia (ED) and the no-early-dysphagia (NED) groups. The recurrence of heartburn or regurgitation, as well as the pH studies on long-term follow-up (more than 6 months) were compared between the two groups. A grading system (range 0-4) was used to measure the severity of foregut symptoms.

RESULTS

1223 patients underwent primary laparoscopic Nissen fundoplications during the study period and met the inclusion criteria. Both short and long-term follow-up was available in 821 patients, who were analyzed. 423 patients were included in the ED group, whereas 398 in the NED group. The mean regurgitation score of the ED group on the long-term follow-up was 0.25 compared to 0.20 for the NED group (P = 0.21). The heartburn score was 0.38 for the ED group compared to 0.33 for the NED group (P = 0.38). Long-term dysphagia was higher in the ED group. These findings were confirmed when ED patients were subclassified based on the degree of early post-operative dysphagia. Of the 821 patients, 599 underwent routine postoperative pH testing. The mean DeMeester score in the ED group (n = 308) was 11.7 compared to 13.2 for the NED group (n = 291; P = 0.54). The percentage of patients with abnormal pH testing was similar between the two groups.

CONCLUSIONS

Early postoperative dysphagia is not associated with worse long-term GERD symptom control after primary laparoscopic antireflux surgery.

Laparoscopic Nissen versus Toupet fundoplication: objective and subjective results of a prospective randomized trial

BACKGROUND

Although symptom outcomes following laparoscopic fundoplication have been adequately evaluated in the past, comparative subjective data of laparoscopic Nissen and Toupet fundoplications are scarce. Multichannel intraluminal impedance monitoring (MII) has not been used so far for comparison of objective data.

METHODS

One hundred patients with documented chronic gastroesophageal reflux disease (GERD) were randomly allocated to either floppy Nissen fundoplication (group I, n = 50) or Toupet fundoplication (group II, n = 50). Gastrointestinal Quality of Life Index (GIQLI), symptom grading, esophageal manometry, and MII data were documented preoperatively and 3 months after surgery. Subjective and objective outcome data were compared to those of healthy individuals.

RESULTS

Symptom intensity was significantly more severe and GIQLI showed impairment in the examined patient population compared to healthy controls. Both procedures resulted in a significant improvement in GIQLI and GERD symptoms (p < 0.01). Dysphagia improved significantly only in group II, while cough, asthma, and distortion of taste improved significantly in both groups. Hoarseness symptoms showed some degree of improvement in both groups but reached statistical significance only in group I. Postoperatively, bowel symptoms partly increased and the ability to belch decreased in both groups (p < 0.05). Comparison of postoperative GIQLI and symptom scores showed no significant difference between the two groups, except for the ability to belch, which was more impaired after Nissen fundoplication. Both procedures resulted in a significant improvement in lower esophageal sphincter (LES) pressure; however, the improvement was greater in group I than in group II. MII data showed more reflux control after Nissen, but the differences between the procedures were not significant.

CONCLUSIONS

Both procedures equally improve quality of life and GERD symptoms. Bowel symptoms may increase after both procedures at the 3-month follow-up. Manometry and MII data favor Nissen fundoplication, but dysphagia and the inability to belch are more common compared to Toupet fundoplication.

Partial or total fundoplication (with or without division of the short gastric vessels): which is the best laparoscopic choice in GERD surgical treatment?

BACKGROUND

Gastroesophageal reflux disease (GERD) has emerged as one of the most common diseases in the modern civilization.The immense success of laparoscopic surgery as an effective treatment of GERD has established the minimally invasive surgery as the gold standard for this condition with lower morbidity and mortality, shorter hospital stay, faster recovery, and reduced postoperative pain.

METHODS

Articles were sourced from PubMed and Medline, using the MeSH terms "gastroesophageal reflux disease" and "laparoscopic surgery" and "fundoplication technique." The selection of articles was based on peer review, journal, relevance, and English language.

RESULTS AND CONCLUSIONS

There are some controversies with regard to the technique. First, whether total or partial fundoplication is the more appropriate treatment for GERD; second, if a total fundoplication (360 degrees) is performed, what is the effect of fundic mobilization and the division of short gastric vessels. In this review article the authors evaluate the most recent articles to establish the parameters for a "gold standard technique" in antireflux surgery.

A meta-analysis comparing laparoscopic partial versus Nissen fundoplication

BACKGROUND

For proven gastro-oesophageal reflux disease, partial fundoplication is considered as effective as Nissen, but with fewer side effects. The aim of this meta-analysis was to compare the effect of laparoscopic partial fundoplication (LPF) with laparoscopic Nissen fundoplication (LNF).

METHODS

Extensive medical literature searches of the PubMed, Medline and Embase databases were performed up to April 2010 for all randomized clinical trials that compared LPF versus LNF. The effect variables analysed were the incidence of post-operative dysphagia, heartburn, inability to belch, outcome or satisfaction and Visick score. Meta-analyses were carried out using odds ratios (ORs) with 95% confidence interval.

RESULTS

Thirteen randomized trials were considered suitable for the meta-analysis. A total of 1374 patients underwent LPF or LNF. There was a significant reduction of the incidence of post-operative dysphagia (OR = 0.44, P < 0.0001) and inability to belch (OR = 0.41, P < 0.005) for the LPF compared to that of the LNF group. Compared with LPF, LNF resulted in a significant reduction of the incidence of post-operative heartburn (OR = 1.94, P < 0.01). The outcome or satisfaction of patients and Visick I and II scores were comparable between the two groups.

CONCLUSION

Both LPF and LNF are effective for the treatment of proven gastro-oesophageal reflux disease. LPF enables a decreased post-operative dysphagia and gas-related side effects, while LNF is more successful in controlling reflux symptoms, particularly heartburn, than LPF. A balance should be found between anti-reflux and side effects.

Evidence-based appraisal in laparoscopic Nissen and Toupet fundoplications for gastroesophageal reflux disease

AIM: To demonstrate the optimal surgical procedure for gastroesophageal reflux disease.

METHODS: The electronic databases of Medline, Elsevier, Springerlink and Embase over the last 16 years were searched. All clinical trials involved in the outcomes of laparoscopic Nissen fundoplication (LNF) and laparoscopic Toupet fundoplication (LTF) were identified. The data of assessment in benefits and adverse results of LNF and LTF were extracted and compared using meta-analysis.

RESULTS: We ultimately identified a total of 32 references reporting nine randomized controlled trials, eight prospective cohort trials and 15 retrospective trials. These studies reported a total of 6236 patients, of whom 4252 (68.18%) underwent LNF and 1984 (31.82%) underwent LTF. There were no differences between LNF and LTF in patients’ satisfaction, perioperative complications, postoperative heartburn, reflux recurrence and re-operation. Both LNF and LTF enhanced the function of lower esophageal sphincter and improved esophagitis. The postoperative dysphagia, gas-bloating syndrome, inability to belch and the need for dilatation after LNF were more common than after LTF. Subgroup analyses showed that dysphagia after LNF and LTF was similar in patients with normal esophageal peristalsis (EP), but occurred more frequently in patients with weak EP after LNF than after LTF. Furthermore, patients with normal EP after LNF still had a higher risk of developing dysphagia than did patients with abnormal EP after LTF.

CONCLUSION: Compared with LNF, LTF offers equivalent symptom relief and reduces adverse results.

Endoscopic and laparoscopic treatment of gastroesophageal reflux

Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.

Evaluating outcomes of endoscopic full-thickness plication for gastroesophageal reflux disease (GERD) with impedance monitoring

BACKGROUND

Endoscopic full-thickness plication allows transmural suturing at the gastroesophageal junction to recreate the antireflux barrier. Multichannel intraluminal impedance monitoring (MII) can be used to detect nonacid or weakly acidic reflux, acidic swallows, and esophageal clearance time. This study used MII to evaluate the outcome of endoscopic full-thickness plication.

METHODS

In this study, 12 subsequent patients requiring maintenance proton pump inhibitor therapy underwent endoscopic full-thickness plication for treatment of gastroesophageal reflux disease. With patients off medication, MII was performed before and 6-months after endoscopic full-thickness plication.

RESULTS

The total median number of reflux episodes was significantly reduced from 105 to 64 (p = 0.016). The median number of acid reflux episodes decreased from 73 to 43 (p = 0.016). Nonacid reflux episodes decreased from 23 to 21 (p = 0.306). The median bolus clearance time was 12 s before treatment and 11 s at 6 months (p = 0.798). The median acid exposure time was reduced from 6.8% to 3.4% (p = 0.008), and the DeMeester scores were reduced from 19 to 12 (p = 0.008).

CONCLUSION

Endoscopic full-thickness plication significantly reduced total reflux episodes, acid reflux episodes, and total reflux exposure time. The DeMeester scores and total acid exposure time for the distal esophagus were significantly improved. No significant changes in nonacid reflux episodes and median bolus clearance time were encountered.

Endoscopic full-thickness plication for the treatment of gastroesophageal reflux disease using multiple Plicator implants: 12-month multicenter study results

BACKGROUND

The full-thickness Plicator (Ethicon Endosurgery, Sommerville, NJ, USA) was developed for endoscopic treatment of gastroesophageal reflux disease (GERD). The goal is to restructure the antireflux barrier by delivering transmural pledgeted sutures through the gastric cardia. To date, studies using this device have involved the placement of a single suture to create the plication. The purpose of this study was to evaluate the 12-month safety and efficacy of this procedure using multiple implants to restructure the gastroesophageal (GE) junction.

METHODS

A multicenter, prospective, open-label trial was conducted at four tertiary centers. Eligibility criteria included symptomatic GERD [GERD Health-Related Quality-of-Life (GERD-HRQL) questionnaire, off of medication], and pathologic reflux (abnormal 24-h pH) requiring daily proton pump inhibitor therapy. Patients with Barrett's epithelium, esophageal dysmotility, hiatal hernia > 3 cm, and esophagitis (grade III or greater) were excluded. All patients underwent endoscopic full-thickness plication with linear placement of at least two transmural pledgeted sutures in the anterior gastric cardia.

RESULTS

Forty-one patients were treated. Twelve months post treatment, 74% of patients demonstrated improvement in GERD-HRQL scores by > or = 50%, with mean decrease of 17.6 points compared with baseline (7.8 vs. 25.4, p < 0.001). Using an intention-to-treat model, 63% of patients had symptomatic improvements of > or = 50%, with mean GERD-HRQL decrease of 15.0 (11.0 vs. 26.0, p < 0.001). The need for daily proton pump inhibitor (PPI) therapy was eliminated in 69% of patients at 12 months on a per-protocol basis, and 59% on an intention-to-treat basis. Adverse events included postprocedure abdominal pain (44%), shoulder pain (24%), and chest pain (17%). No long-term adverse events occurred.

CONCLUSIONS

Endoscopic full-thickness plication using multiple Plicator implants can be used safely and effectively to improve GERD symptoms and reduce medication use.

Recurrent symptoms after fundoplication with a negative pH study--recurrent reflux or functional heartburn?

INTRODUCTION

A small cohort of patients present after antireflux surgery complaining of recurrent heartburn. Over two thirds of these patients will have a negative 24-h pH study. The aim of our study is to determine whether these patients have an associated functional disorder or abnormal cytokine activity and to examine the reproducibility of pH testing.

METHODS

A prospective analysis was carried out on a cohort of patients who had undergone a fundoplication and postoperative pH testing for recurrent heartburn: group A--patients with recurrent heartburn and a negative 24-h pH study and group B (control group)--patients with recurrent heartburn and a positive pH study. Questionnaires, a blood sample, and repeat pH testing were completed.

RESULTS

Sixty-nine patients were identified. Group A's depression score (8.6 +/- 4.1) was significantly higher than group B's (5.9 +/- 4.2; P = 0.03). Cytokine levels were similar in both groups. Forty-seven of 49 (96%) patients who underwent repeat pH testing had a negative study. Symptom-reflux correlation was highly significant (P < 0.001).

CONCLUSION

Some patients with recurrent heartburn and a negative pH study have associated functional or psychiatric comorbidities such as depression. Reproducibility of 24-h pH testing in these patients is excellent.

Ten-year clinical outcome of a prospective randomized clinical trial of laparoscopic Nissen versus anterior 180( degrees ) partial fundoplication

BACKGROUND

A randomized trial of laparoscopic Nissen fundoplication and anterior 180 degrees partial fundoplication was undertaken to determine whether the anterior procedure might reduce the incidence of dysphagia and other adverse outcomes following surgery for gastro-oesophageal reflux disease. This study evaluated clinical outcomes after 10 years.

METHODS

Some 107 patients were randomized to undergo laparoscopic Nissen or anterior 180 degrees partial fundoplication. Ten-year data were not available for 18 patients. Information was obtained from 89 patients (48 Nissen, 41 anterior fundoplication) using a standard clinical questionnaire that focused on symptoms of reflux, potential postoperative side-effects and overall satisfaction with the outcome of surgery.

RESULTS

There were no significant differences between the two groups with regard to reflux symptoms, dysphagia, abdominal bloating, ability to belch and overall satisfaction. Between 5 and 10 years after surgery, revisional surgery was required for reflux in two patients after anterior fundoplication. Two patients had revision after Nissen fundoplication, for reflux and recurrent hiatus hernia.

CONCLUSION

Both laparoscopic anterior 180 degrees partial and Nissen fundoplication are safe, effective and durable at 10 years' follow-up. Most patients are satisfied with the clinical outcome.
