Quality of life and symptomatic outcome three to five years after laparoscopic Toupet fundoplication in gastroesophageal reflux disease patients with impaired esophageal motility

Antireflux Surgery Versus Antireflux Medication and Risk of Esophageal Adenocarcinoma in Patients With Barrett's Esophagus

BACKGROUND & AIMS

Antireflux treatment is recommended to reduce esophageal adenocarcinoma in patients with Barrett's esophagus. Antireflux surgery (fundoplication) counteracts gastroesophageal reflux of all types of carcinogenic gastric content and reduces esophageal acid exposure to a greater extent than antireflux medication (eg, proton pump inhibitors). We examined the hypothesis that antireflux surgery prevents esophageal adenocarcinoma to a larger degree than antireflux medication in patients with Barrett's esophagus.

METHODS

This multinational and population-based cohort study included all patients with a diagnosis of Barrett's esophagus in any of the national patient registries in Denmark (2012-2020), Finland (1987-1996 and 2010-2020), Norway (2008-2020), or Sweden (2006-2020). Patients who underwent antireflux surgery were compared with nonoperated patients using antireflux medication. The risk of esophageal adenocarcinoma was calculated using multivariable Cox regression, providing hazard ratios (HRs) and 95% CIs adjusted for age, sex, country, calendar year, and comorbidity.

RESULTS

The cohort consisted of 33,939 patients with Barrett's esophagus. Of these, 542 (1.6%) had undergone antireflux surgery. During up to 32 years of follow-up, the overall HR was not decreased in patients having undergone antireflux surgery compared with nonoperated patients using antireflux medication, but rather increased (adjusted HR, 1.9; 95% CI, 1.1-3.5). In addition, HRs did not decrease with longer follow-up, but instead increased for each follow-up category, from 1.8 (95% CI, 0.6-5.0) within 1-4 years of follow-up to 4.4 (95% CI, 1.4-13.5) after 10-32 years of follow-up.

CONCLUSIONS

Patients with Barrett's esophagus who undergo antireflux surgery do not seem to have a lower risk of esophageal adenocarcinoma than those using antireflux medication.

Lap. Nissen fundoplication leads to better respiratory symptom control than Toupet in the long term of 20 years

INTRODUCTION

Having performed anti-reflux surgery for thirty years, it was important to reexamine our patients in the long term to enlarge the body of evidence concerning classical and extraesophageal symptoms that are differently controlled by Nissen or Toupet fundoplication.

OBJECTIVES

We report a cohort of 155 GERD patients who underwent fundoplication within a tailored approach between 1994 and 2000. Changes in the perioperative functional outcome, GERD symptoms, and quality of life are being analyzed 10 and 20 years after the operation.

RESULTS

The operation resulted in a superior quality of life compared to a patient cohort treated with PPI therapy. We found that both surgical methods (laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication) cure classical symptoms equally (heartburn, regurgitation, and dysphagia). GERD patients receiving a Toupet fundoplication seem more likely to suffer from extraesophageal GERD symptoms 10 and 20 years after surgery than patients with a Nissen fundoplication. On the other hand, some patients with Nissen fundoplication report dysphagia even 10 and 20 years after surgery.

CONCLUSION

Both the laparoscopic Nissen and Toupet fundoplications provide excellent symptom control in the long term. Moreover, the Nissen fundoplication seems to be superior in controlling extraesophageal reflux symptoms, but at the expense of dysphagia. In summary, tailoring the operation based on symptoms seems advantageous.

Quality of life in benign colorectal disease-a review of the assessment with the Gastrointestinal Quality of Life Index (GIQLI)

BACKGROUND AND PURPOSE

The Gastrointestinal Quality of Life Index (GIQLI) is an instrument for the assessment of quality of life (QOL) in diseases of the upper and lower GI tract, which is validated in several languages around the world. The purpose of this literature review is the assessment of the GIQLI in patients with benign colorectal diseases. Reports on GIQLI data are collected from several institutions, countries, and different cultures which allows for comparisons, which are lacking in literature.

METHODS

The GIQL Index uses 36 items around 5 dimensions (gastrointestinal symptoms (19 items), emotional dimension (5 items), physical dimension (7 items), social dimension (4 items), and therapeutic influences (1 item). The literature search was performed on the GIQLI and colorectal disease, using reports in PubMed. Data are presented descriptively as GIQL Index points as well as a reduction from 100% maximum possible index points (max 144 index points = highest quality of life).

RESULTS

The GIQLI was found in 122 reports concerning benign colorectal diseases, of which 27 were finally selected for detailed analysis. From these 27 studies, information on 5664 patients (4046 female versus 1178 male) was recorded and summarized. The median age was 52 years (range 29-74.7). The median GIQLI of all studies concerning benign colorectal disease was 88 index points (range 56.2-113). Benign colorectal disease causes a severe reduction in QOL for patients down to 61% of the maximum.

CONCLUSIONS

Benign colorectal diseases cause substantial reductions in the patient's QOL, well documented by GIQLI, which allows a comparison QOL with other published cohorts.

Gastrointestinal Quality of Life in Gastroesophageal Reflux Disease: A Systematic Review

BACKGROUND

The Gastrointestinal Quality of Life Index (GIQLI) is a well-established instrument for the assessment of quality of life (QOL) in gastrointestinal (GI) diseases. The purpose of this literature review was to investigate QOL by means of GIQLI in patients with gastroesophageal reflux disease (GERD) prior to any interventional therapy. There are several reports on GIQLI data; however, comparisons from different countries and/or different GERD cohorts assessing the same disease have to date not been conducted.

METHODS

The GIQLI uses 36 items around 5 dimensions (GI symptoms [19 items], emotional dimension [5 items], physical dimension [7 items], social dimension [4 items], and therapeutic influences [1 item]). A literature search was conducted on the application of GIQLI in GERD patients prior to interventional therapy using reports in PubMed. Data on the mean GIQLI as well as index data for the 5 dimensions as originally validated were extracted from the published patient cohorts. A comparison with the normal healthy control group from the original publication of the GIQLI validation conducted by Eypasch was performed. Data are presented descriptively as GIQLI points as well as a reduction from 100% maximum possible index points (max 144 index points = highest QOL).

RESULTS

In total, 77 abstracts from studies using the GIQLI on patients with GERD were identified. After screening for content, 21 publications were considered for further analysis. Ten studies in GERD patients comprised complete calculations of all dimensions and were included in the analysis. Data from 1,682 study patients were evaluated with sample sizes ranging from 33 to 568 patients (median age of 789 females and 858 males: 51.8 years). The median overall GIQLI for the patient group was 91.7 (range 86-102.4), corresponding to 63.68% of the maximum GIQLI. The dimensions with the largest deviation from the respective maximum score were the physical dimension (55% of maximum) followed by the emotional dimension (60% of maximum). In summary, the GIQLI level in GERD cohorts was reduced to 55-75% of the maximum possible index.

CONCLUSIONS

Severe GERD causes substantial reductions in the patient's QOL. The level of GIQLI can carry between different studied GERD cohorts from different departments and countries. GIQLI can be used as an established tool to assess the patient's condition in various dimensions.

Complete Fundus Mobilization Reduces Dysphagia After Nissen Procedure

Background. Anti-reflux surgery is an effective treatment for gastroesophageal reflux disease (GERD). Nevertheless, surgery is still indicated with great caution in relation to the risk of complications, and in particular to postoperative dysphagia (PD). Objective. To compare the clinical outcomes, with particular focus on the incidence and severity of PD, of laparoscopic Nissen-Rossetti fundoplication (NRF) and floppy Nissen fundoplication (FNF) with complete fundus mobilization, in the surgical treatment of GERD. Methods. Ninety patients with GERD were enrolled. Forty-four patients (21[47.7%] men, 23[52.2%] women; mean age 42.4 ± 14.3 years) underwent NRF (Group A), and 46 patients (23[50%] men, 23[50%] women; mean age 43.3 ± 15.4 years) received laparoscopic FNF with complete fundus mobilization (Group B). Clinical assessment was performed using a structured questionnaire and SF-36 quality of life (QoL) score. PD was assessed using a validated classification, and an overall outcome was also determined by asking the patient to score it. Results. At 24-month follow-up, 38 (88.3%) patients in Group A vs 39 (86.6%) in Group B reported to be completely satisfied with reflux relief and free of protonic pump inhibitors (PPIs), while 3 (6.9%) in Group A vs 2(4.4%) in Group B reported occasional PPI intake and 2(4.6%) in Group A vs 4(8.8%) in Group B needed regular PPI use. Persistent PD was observed in 8(18.6%) patients in Group A and in 2(4.4%) in Group B (P = .03). No significant differences were found in the QoL score and in the overall outcome perceived by the patients. Conclusion. FNF, with complete fundus mobilization, appears to be associated with a lower rate of postoperative persistent dysphagia.

Advances in the diagnosis and management of gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is a multifaceted disorder encompassing a family of syndromes attributable to, or exacerbated by, gastroesophageal reflux that impart morbidity, mainly through troublesome symptoms. Major GERD phenotypes are non-erosive reflux disease, GERD hypersensitivity, low or high grade esophagitis, Barrett's esophagus, reflux chest pain, laryngopharyngeal reflux, and regurgitation dominant reflux. GERD is common throughout the world, and its epidemiology is linked to the Western lifestyle, obesity, and the demise of Helicobacter pylori. Because of its prevalence and chronicity, GERD is a substantial economic burden measured in physician visits, diagnostics, cancer surveillance protocols, and therapeutics. An individual with typical symptoms has a fivefold risk of developing esophageal adenocarcinoma, but mortality from GERD is otherwise rare. The principles of management are to provide symptomatic relief and to minimize potential health risks through some combination of lifestyle modifications, diagnostic testing, pharmaceuticals (mainly to suppress or counteract gastric acid secretion), and surgery. However, it is usually a chronic recurring condition and management needs to be personalized to each case. While escalating proton pump inhibitor therapy may be pertinent to healing high grade esophagitis, its applicability to other GERD phenotypes wherein the modulating effects of anxiety, motility, hypersensitivity, and non-esophageal factors may dominate is highly questionable.

Ineffective Esophageal Motility in Patients with GERD is no Contraindication for Nissen Fundoplication

BACKGROUND

Patients with preoperative ineffective esophageal motility (IEM) are thought to be at increased risk for postoperative dysphagia leading to the recommendations for tailoring or avoiding anti-reflux surgery in these patients. The aim of this study was to evaluate if IEM has an influence on postoperative outcome after laparoscopic Nissen fundoplication (LNF).

METHODS

Seventy-two consecutive patients with IEM underwent LNF and were case-matched with 72 patients without IEM based on sex, age, BMI, HH size, total pH percentage time, total number of reflux episodes and the presence of BE. Standardized interview assessing postoperative gastrointestinal symptoms, proton pump inhibitor intake, GERD-health-related-quality-of-life (GERD-HRQL), alimentary satisfaction and patients' overall satisfaction was evaluated.

RESULTS

Although a higher rate of preoperative dysphagia was observed in patients with IEM (29% IEM vs. 11% no IEM, p = 0.007), there was no significant difference in rates of dysphagia postoperatively (2 IEM vs. 1 no IEM, p = 0.559). Furthermore, no distinction was found in the postoperative outcome regarding symptom relief, quality of life, gas bloating syndrome, ability to belch and/or vomit or revision surgery between the two groups.

CONCLUSION

Although preoperative IEM has an influence on GERD presentation, it has no effect on postoperative outcome after LNF. IEM should not be a cause for avoiding LNF, as is has been shown as the most effective and safe anti-reflux treatment.

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.

Typical symptoms and not positive reflux-cough correlation predict cure of gastroesophageal reflux disease related chronic cough after laparoscopic fundoplication: a retrospective study

Background

The effect of laparoscopic fundoplication on reflux-related chronic cough is unpredictable, the aim of the study is to investigate the predictive effect of positive reflux-cough correlation on the resolution of reflux-related chronic cough after anti-reflux surgery.

Methods

A 5 years retrospective review was performed. Logistic regression analysis was used to determine the independent predictors on the cure of chronic cough.

Results

Seventy-nine patients were included in this study, among which chronic cough was cured in 47 (59.5%) and significantly improved in 10 (12.7%) patients. Present of typical symptoms (odds ratio = 6.435,95% confidence interval [CI] = 1.427–29.032, p = 0.015) and number of Reflux episodes (impedance) ≥73 (odds ratio = 0.306, 95% confidence interval [CI] = 0.107–0.874, p = 0.027) were significantly associated with the cure of chronic cough.

Conclusions

laparoscopic fundoplicaiton is effective for the management of reflux-related chronic cough, particularly with the present of typical symptoms.

Persistent dysphagia is a rare problem after laparoscopic Nissen fundoplication

BACKGROUND

Although around 30% of patients with gastroesophageal reflux disease (GERD) are insufficiently treated with medical therapy, only 1% opt for surgical therapy. One of the reasons behind this multifactorial phenomenon is the described adverse effect of long-term dysphagia or gastric bloating syndrome after surgical treatment. Aim of this study was to evaluate the most common side effects associated with anti-reflux surgery, as well as long-term outcomes in a large cohort of highly surgically standardized patients after laparoscopic Nissen fundoplication (LNF).

METHODS

Out of a prospective patients' database including all patients that underwent anti-reflux surgery between 01/2003 and 01/2017 at our institution, 350 consecutive patients after highly standardized LNF were included in this study. A standardized interview was performed by one physician assessing postoperative gastrointestinal symptoms, proton pump inhibitor intake (PPI), GERD-Health-Related-Quality-of-Life (GERD-HRQL), Alimentary Satisfaction (AS), and patients' overall satisfaction.

RESULTS

After a median follow-up of 4 years, persistent dysphagia (PD) after LNF was observed in 8 (2%) patients, while postoperative gas-bloat syndrome in 45 (12.7%) cases. Endoscopic dilatation was needed in 7 (2%) patients due to dysphagia, and 19 (5%) patients underwent revision surgery due to recurrence of GERD. The postoperative GERD-HRQL total score was significantly reduced (2 (IQR 0-4.3) vs. 19 (IQR 17-32); p < 0.000) and the median AS was 9/10. Heartburn relief was achieved in 83% of patients. Eighty-three percent of patients were free of PPI intake after follow-up, whereas 13% and 4% of the patients reported daily and irregular PPI use, respectively.

CONCLUSION

LNF is a safe and effective surgical procedure with low postoperative morbidity rates and efficient GERD-related symptom relief. PD does not represent a relevant clinical issue when LNF is performed in a surgical standardized way. These results should be the benchmark to which long-term outcomes of new surgical anti-reflux procedures are compared.

Psychosocial Factors Are Associated with Quality of Life After Laparoscopic Antireflux Surgery

BACKGROUND

Laparoscopic antireflux surgery (LARS) is the gold standard treatment for refractory gastroesophageal reflux disease (GERD). Traditional surgical outcomes following LARS are well described, but limited data exist regarding patient-reported outcomes. We aimed to identify preoperative characteristics that were independently associated with a high GERD health-related quality of life (GERD-HRQL) following LARS.

METHODS

Clinical data from our single institution foregut surgery database were used to identify all patients with GERD who underwent primary LARS from June 2010 to November 2015. Electronic health record data were reviewed to extract patient characteristics, diagnostic study characteristics, and operative data. Postoperative GERD-HRQL data were obtained through telephone follow-up. Variables hypothesized a priori to be associated with high GERD-HRQL after LARS, which were significant at P ≤ .2 on bivariate analysis, were entered into a multivariable linear regression model with GERD-HRQL as the outcome.

RESULTS

The study included 248 patients; 69.0% were female, 56.9% were married, and 58.1% had concurrent atypical symptoms. The most commonly performed fundoplications were Nissen (44.8%), Toupet (41.3%), and Dor (14.1%), respectively. The median follow-up interval was 3.4 years. The telephone response rate was 60.1%. GERD-HRQL scores improved from 24.8 (SD ±11.4) preoperatively to 3.0 (SD ±5.9) postoperatively. 79.9% of patients were satisfied with their condition at follow-up. On multivariable analysis, being married (P = .04) and absence of depression (P = .02) were independently associated with a higher postoperative QoL.

CONCLUSIONS

Strong social support and psychiatric well-being appear to be important predictors of a higher QoL following LARS. Optimizing social support and treating depression preoperatively and postoperatively may improve QoL outcomes for LARS patients.

Effect of laparoscopic antireflux surgery on esophageal motility

BACKGROUND/AIMS

The effect of laparoscopic antireflux surgery on esophageal motility is incompletely understood, and any indication for this procedure in patients with motility disorder is disputed in literature. We evaluated the influence of laparoscopic Nissen fundoplication on impaired esophageal motility.

METHODS

In this pathological manometric study, we divided the patients into two groups preoperatively: the hypomotility group (mean amplitude of esophageal contraction wave <40 mm Hg; HYPO group, n = 11) and the normal group (mean amplitude of esophageal contraction wave >40 mm Hg; NORM group, n = 43). The amplitudes of esophageal contraction waves 3 and 8 cm above the lower esophageal sphincter and the percentage of peristaltic contraction waves of the tubular esophagus were analyzed pre- and postoperatively.

RESULTS

In total, 54 patients with GERD underwent esophageal manometry before and 6 months after Nissen fundoplication. The length and pressure of the lower esophageal sphincter were increased in both groups postoperatively (p < 0.01). Patients in the HYPO group (n = 11) showed a statistically significant increase of mean amplitude of esophageal contraction (32.8 vs. 57.3 mm Hg; p < 0.01), while no change was found in the NORM group (n = 43). A total of 72% of patients with preoperative motility disorder showed normal postoperative manometry.

CONCLUSION

Nissen fundoplication normalizes esophageal motility, especially in patients with preoperative hypomotility. Patients with impaired esophageal motility should not per se be excluded from antireflux surgery.

Systematic review: Laparoscopic fundoplication for gastroesophageal reflux disease in partial responders to proton pump inhibitors

AIM: To assess laparoscopic fundoplication (LF) in partial responders to proton pump inhibitors (PPIs) for gastroesophageal reflux disease (GERD).

METHODS: We systematically searched PubMed and Embase (1966-Dec 2011) for articles reporting data on LF efficacy in partial responders. Due to a lack of randomized controlled trials, observational studies were included. Of 558 articles screened, 17 were eligible for inclusion. Prevalence data for individual symptoms were collated across studies according to mutually compatible time points (before and/or after LF). Where suitable, prevalence data were presented as percentage of patients reporting symptoms of any frequency or severity.

RESULTS: Due to a lack of standardized reporting of symptoms, the proportion of patients experiencing symptoms was recorded across studies where possible. After LF, the proportion of partial responders with heartburn was reduced from 93.1% (5 studies) to 3.8% (5 studies), with similar results observed for regurgitation [from 78.4% (4 studies) to 1.9% (4 studies)]. However, 10 years after LF, 35.8% (2 studies) of partial responders reported heartburn and 29.1% (1 study) reported regurgitation. The proportion using acid-suppressive medication also increased, from 8.8% (4 studies) in the year after LF to 18.2% (2 studies) at 10 years. In the only study comparing partial responders to PPI therapy with complete responders, higher symptom scores and more frequent acid-suppressive medication use were seen in partial responders after LF.

CONCLUSION: GERD symptoms improve after LF, but subsequently recur, and acid-suppressive medication use increases. LF may be less effective in partial responders than in complete responders.

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.

Age and body mass index: significant predictive factors for successful laparoscopic antireflux surgery

PURPOSE

Laparoscopic antireflux surgery (LARS) is a feasible treatment for gastroesophageal reflux disease (GERD) patients, but it is unclear who will benefit from the surgery. This study investigated patients' GERDspecific quality of life (GsQOL) and analyzed the factors leading to the performance of successful LARS.

METHODS

Twenty-six (57.8%) of 45 consecutive patients who underwent LARS for GERD during the last decade were enrolled. All patients were evaluated by 24-h pH monitoring, esophageal manometry, esophagogastro-duodenoscopy and physical examinations. GsQOL was assessed by a visual analog scale, and the difference between the pre- and postoperative scores was defined as the visual analog scale improvement score (VASIS). The patients were classified into three groups based on the VASIS, and their clinical factors and surgical outcomes were compared.

RESULTS

The high VASIS group patients (>70 VASIS; Excellent group) patients were significantly younger and obese in comparison to low the VASIS group (<30 VASIS; Poor group) consisting of older nonobese patients (P < 0.05). A multiple regression analysis revealed that age <60 years and body mass index (BMI) >25 kg/m(2) were significant factors that affected postoperative GsQOL. No other clinical or surgical factors had any influence on the postoperative GsQOL.

CONCLUSION

These results suggest that age and BMI can be predictive factors for the performance of successful LARS.

The laparoscopic Nissen fundoplication--a better operation?

BACKGROUND

Laparoscopic Nissen fundoplication has become the method of choice in antireflux surgery replacing its open counterpart before the long-term results of controlled clinical trials were available. METHODS AND AIM: Review of the literature to highlight the long-term results of laparoscopic Nissen fundoplication.

RESULTS

Long-term symptom relief regarding significant reflux symptoms of heartburn and regurgitation can be achieved by laparoscopic fundoplication in 84% to 97% and patients' overall satisfaction with the result of their laparoscopic fundoplication surgery is high, ranging from 86% to 96%. The long-term results of randomised trials have shown no statistically significant differences in subjective symptomatic outcome between laparoscopic and open Nissen fundoplication. Complaints regarding the scar, incisional hernias and higher incidence of defective wraps were associated with the open approach.

CONCLUSION

At long-term follow-up the laparoscopic Nissen fundoplication has a similar long-term subjective symptomatic outcome as the open procedure but laparoscopic Nissen fundoplication is associated with a significantly lower incidence of incisional hernias and defective fundic wraps at endoscopy, defining laparoscopic Nissen fundoplication as the procedure of choice in surgical management of gastro-oesophageal reflux disease.

Five-year subjective and objective results of laparoscopic and conventional Nissen fundoplication: a randomized trial

OBJECTIVE

The purpose of this prospective study was to compare the subjective and objective outcome of laparoscopic (LNF) and conventional Nissen fundoplication (CNF) up to 5 years after surgery as obtained in a multicenter randomized controlled trial.

SUMMARY OF BACKGROUND DATA

LNF is regarded as surgical treatment of first choice for refractory gastroesophageal reflux disease by many surgeons based on several short- and mid-term studies. The long-term efficacy of Nissen fundoplication, however, is still questioned as objective data gathered from prospective studies are lacking.

METHODS

From 1997 to 1999, 177 patients were randomized to undergo LNF or CNF. Five years after surgery, all patients were requested to fill in questionnaires and to undergo esophageal manometry and 24-hour pH-metry.

RESULTS

A total of 148 patients agreed to participate in the follow-up study: 79 patients after LNF and 69 after CNF. Of these, 97 patients (48 LNF, 49 CNF) consented to undergo esophageal manometry and 24-hour pH-metry. At 5 years follow-up, 20 patients had undergone reoperation: 12 after LNF (15%) and 8 after CNF (12%). There was no difference in subjective outcome, with overall satisfaction rates of 88% and 90%, respectively. Total esophageal acid exposure times (pH < 4) were 2.1% +/- 0.5% and 2.0% +/- 0.6%, respectively (P = 0.21). Antisecretory medication was taken daily in 14% and 16%, respectively (P = 0.29). There was no correlation between medication use and acid exposure and indices of symptom-reflux association (symptom index and symptom association probability). No significant differences between subjective and objective results at 3 to 6 months and results obtained at 5 years after surgery were found.

CONCLUSIONS

The effects of LNF and CNF on general state of health and objective reflux control are sustained up to 5 years after surgery and the long-term results of LNF and CNF are comparable. A substantial minority of patients in both groups had a second antireflux operation or took antisecretory drugs, although the use of those medications did not appear to be related to abnormal esophageal acid exposure.

Evaluation of health-related quality of life in gastroesophageal reflux disease patients before and after treatment with pantoprazole

Gastrooesophageal reflux disease (GERD) is highly prevalent in the Western world but its true population prevalence is difficult to estimate without a validated instrument to detect it. The evaluation of health-related quality of life (HRQoL) is an useful tool in this assessment. The aims of this study are to translate and validate a GERD specific HRQoL questionnaire and evaluate HRQoL in a Brazilian population before and after GERD treatment. GERD patients with typical symptoms and Los Angeles Classes A to C esophagitis were included in the study. Two HRQoL questionnaires and upper digestive endoscopy were performed before and after 6 weeks treatment with pantoprazole 40 mg/day followed by 80 mg/day for another 8 weeks if healing did not occur. A generic (SF-36) and one disease-specific questionnaire (GERD score) were used. The latter was translated and validated for Brazilian Portuguese. From January 2002 to December 2003, 100 patients were enrolled. Of these, 78 patients were evaluated in a per protocol analysis (35 men, mean age: 40 years). The translated questionnaire (Brazilian GERD Score, BGERDS) demonstrated adequate psychometric properties (validity, responsiveness and reliability). SF-36 and BGERDS domains significantly improved after treatment (P < 0.01 and P < 0.001 respectively). The BGERDS was shown to be valid and reliable. Patients with esophagitis showed an impaired HRQoL that improved or normalized after treatment with pantoprazole.

Effects of laparoscopic Nissen fundoplication on esophageal motility

BACKGROUND

This study aimed to evaluate the long-term impact of laparoscopic Nissen fundoplication on esophageal motility in patients with preoperative esophageal dysmotility.

METHODS

This study prospectively followed 580 patients who underwent laparoscopic Nissen fundoplication between 1992 and 1999. Esophageal manometry, 24-h pH monitoring, and symptom score assessment were performed before surgery, then 6 months, 2 years, and 5 years after surgery. Preoperatively, 533 of the patients (93.5%) had normal esophageal contractile pressure (group 1), whereas 38 of the patients (6.5%) had reduced contractile pressure (<30 mmHg) (group 2).

RESULTS

Esophageal contractile pressures increased significantly in the patients with low preoperative values, whereas it remained unchanged in the patients with normal preoperative contractile pressures. Both groups reported a significant reduction in the dysphagia symptom score after surgery.

CONCLUSION

Nissen fundoplication produces a significant long-lasting increase in esophageal contractile pressures in patients with preoperative esophageal dysmotility (i.e., contractile pressure lower than 30 mmHg). Preoperative esophageal dysmotility is therefore not a contraindication to laparoscopic Nissen fundoplication.

Citric acid cough threshold in patients with gastroesophageal reflux disease rises after laparoscopic fundoplication

BACKGROUND

It has been reported that antireflux surgery can diminish chronic cough due to gastroesophageal reflux disease (GERD) that is resistant to pharmacologic therapy. The aim of this study was the assessment of citric acid cough threshold (CACT) in patients with chronic cough due to GERD before and 3 months after laparoscopic Toupet fundoplication.

METHODS

Thirty subjects (20 women and 10 men; median age, 45.3 years) with chronic cough due to GERD and 15 healthy volunteers underwent cough challenge with doubling concentrations of citric acid. Twenty subjects with GERD, a group of 14 women and 6 men (mean age, 45.5 years), underwent the same protocol 3 months after laparoscopic fundoplication. Daytime and nighttime cough score questionnaires (verbal category descriptive score) were completed in all groups.

RESULTS

The geometric mean of CACT was significantly lower in GERD patients (9.62 mg/mL) than in healthy volunteers (50.8 mg/mL, p < 0.001). The results of cough score measurement significantly improved within 2 weeks after laparoscopic surgery. In 13 weeks of postoperative follow-up, cough disappeared or was greatly improved in 14 of the 20 patients (70%); in 3 other patients, cough resolved partially. In three patients. there was no improvement in cough. Cough challenge after surgery revealed a significant increase in mean cough threshold, from 8.28 to 19.03 mg/mL (p < 0.05).

CONCLUSIONS

The results suggest that GERD influences CACT, which was significantly lower in GERD patients compared to healthy subjects. A significant correlation was found between subjective and objective measurements of cough in GERD patients. We found laparoscopic fundoplication to be objectively beneficial in GERD-induced chronic cough, as it reduced the CACT.

Laparoscopic reoperative surgery after laparoscopic fundoplication: an initial experience

BACKGROUND

Primary fundoplication results are good to excellent. We explored failure patterns and results of redo fundoplication surgery.

STUDY DESIGN

Between January 1999 and July 2002, 10 redo laparoscopic fundoplications were attempted, 1 for the third time. Indications were large symptomatic hiatal hernia-2, hiatal hernia with reflux-2, hiatal hernia with reflux and dysphagia-1, hiatal hernia with dysphagia-2, bloating with dysphagia-1, dysphagia-1, and dysphagia for the third attempt.

RESULTS

Two conversions (20%) were caused by dense adhesions at the crura and mediastinum. There were 8 recurrent hiatal hernia repairs. Fundoplication was left in place in 2 patients. Fundoplication was redone in 4 (2 were slipped), converted to Toupet in 2, or taken down in 1 (with esophageal myotomy). Pyloroplasty was performed in 2 patients and cruroplasty in 1. Laparoscopy operating room time was 140 (64 to 210) minutes and converted 210 and 295 minutes. Intraoperative complications occurred in 30% of patients (gastric perforation 1, bilateral chest tubes 2). Length of hospital stay was 3 (1 to 8) days for laparoscopic, 3 and 5 for converted. One patient was reoperated on acutely for a hiatal reherniation. Follow-up was 16 (1 to 40) months: 3 were symptom free, 2 had mild reflux symptoms, and were on prn H2 blockers, 1 mild bloating, 2 mild dysphasia, 2 moderate dysphagia, 1 had been dilated, and the other failed dilation and was redone.

CONCLUSIONS

Hiatal hernia was the most common cause of symptoms leading to redo surgery. Laparoscopic redo surgery is effective for dysphagia and recurrent heartburn. Results are not as good as for first-time fundoplication and morbidity is higher.

The Impact of Minimally Invasive Surgical Techniques

The use of minimally invasive techniques (MIT) in patient care is well documented in ancient history; however, it was not until the 1990s that advancements in technology enabled surgeons to realize the true potential of this approach. The minimally invasive approach has revolutionized surgical care, significantly reducing postoperative pain, recovery time, and hospital stays with marked improvements in cosmetic outcome and overall cost-effectiveness. It is now used around the world and in all major fields of surgery, compelling changes in training programs in order to assure quality control and patient safety. The bond between surgeons practicing minimally invasive surgery (MIS) and the high-tech industry is of utmost importance to future developments. Surgical robotic systems represent the most technologically advanced product of this collaboration, and their potential application in MIS shows much promise. As technology advances, additional developments in MIT are likely.

Medication usage and additional esophageal procedures after antireflux surgery

One of the goals of antireflux surgery (ARS) is to lower medications usage for heartburn symptoms. There has been some controversy as to whether this is accomplished by surgery. In addition, there is little comparative data of medical usage in patients suffering from gastroesophageal reflux disease (GERD) treated nonoperatively with those treated with surgery, and no data on additional esophageal procedures, such as upper endoscopy or dilation. The purpose of this study was to determine these differences in a matched group of medically and surgically treated patients with at least 1 year of follow-up. All patients who underwent ARS with at least 1 year of follow-up were included. These patients were matched to a group of medically treated patients for gender, age, and month of surgery to month of gastroenterologic clinic visit. Information was gathered through the medical record or direct contact for the present use of medications and additional esophageal procedures related to GERD. One hundred twenty-two patients in each group were studied. Medication usage consisted of 13% of ARS patients versus 95% of medical patients (P < 0.0001). ARS patients had used 359 patient-months of medications versus 3578 in the medical group (P < 0.0001). Only 25% of ARS patients prescribe medications actually responded to their use. Additional procedures consisted of 9% of ARS patients versus 64% of medical patients (P < 0.0001). In conclusion, ARS leads to decreased medication use and to decreased use of subsequent esophageal procedures. In addition, most postoperative ARS patients placed on medications do not respond, and therefore require an objective evaluation for their symptoms.

Long-term follow-up after laparoscopic refundoplication for failed antireflux surgery: quality of life, symptomatic outcome, and patient satisfaction

Quality of life and patient satisfaction have been shown to be important factors in evaluating outcome of laparoscopic antireflux surgery (LARS). The aim of this study was to evaluate data pertaining to quality of life, patient satisfaction, and changes in symptoms in patients who underwent laparoscopic redo surgery after primary failed open or laparoscopic antireflux surgery 3 to 5 years postoperatively. Between March 1995 and June 1998, a total of 27 patients whose mean age was 57 years (range 35 to 78 years) underwent laparoscopic refundoplication for primary failed open or laparoscopic antireflux surgery. Quality of life was evaluated by means of the Gastrointestinal Quality of Life Index (GIQLI). Additionally, patient satisfaction and symptomatic outcome were evaluated using a standardized questionnaire. Three to 5 years after laparoscopic refundoplication, patients rated their quality of life (GIQLI) in an overall score of 113.4 points. Twenty-five patients (92.6%) rated their satisfaction with the redo procedure as very good and would undergo surgery again, if necessary. These patients were no longer taking any antireflux medication at follow-up. Two patients (7.4%) reported rare episodes of heartburn, which were managed successfully with proton pump inhibitors on demand, and four patients (14.8%) reported some episodes of regurgitation but with no decrease in quality of life. Seven patients (25.9%) suffer from mild-to-moderate dysphagia 5 years postoperatively, and 12 patients (44.4%) report having occasional chest pain but no other symptoms of gastroesophageal reflux disease. Nine of these patients suffer from concomitant cardiopulmonary disease. Laparoscopic refundoplication after primary failed antireflux surgery results in a high degree of patient satisfaction and significant improvement in quality of life with a good symptomatic outcome for a follow-up period of 3 to 5 years after surgery.

Gastric surgery

Most significant research relating to gastric surgery in the past year has centered on surgery for gastroesophageal reflux disease (GERD). Antireflux surgery has become more popular with advanced laparoscopic technology. Two previously accepted surgical principles have been challenged by current studies: the importance of division of the short gastrics and the dictum that partial fundoplication is preferred for patients at risk for dysphagia. Additionally, risk factors for postoperative dysphagia have been identified, allowing for better patient selection and education. Further study on the cause of GERD has shown a positive correlation between pathologic gastroesophageal reflux and those with hiatal hernia or disordered esophageal peristalsis, although cause or effect has not yet been established. Literature relating to bariatric surgery has confirmed the safety and efficacy of the laparoscopic Roux-en-Y gastric bypass, and several papers address the appropriateness of prophylactic cholecystectomy in these patients. The role of laparoscopic surgery for treatment of perforated peptic ulcer disease has now been validated, with subsequent eradication of Helicobacter pylori infection. The relationship of H. pylori infection to acutely bleeding ulcers is less clear. Indications for ulcer surgery are predominantly limited now to perforation and bleeding because of the availability of effective acid-reducing medications and recognition of the role of H. pylori infection.
