Laparoscopic toupet fundoplication for gastroesophageal reflux disease with poor esophageal body motility

Impaired esophageal body motility is a complication of chronic gastroesophageal reflux disease (GERD). In patients with this disease, a 360-degree fundoplication may result in severe postoperative dysphagia. Forty-six patients with GERD who had a weak lower esophageal sphincter pressure and a positive acid reflux score associated with impaired esophageal body peristalsis in the distal esophagus (amplitude <30 mm Hg and >10% simultaneous or interrupted waves) were selected to undergo laparoscopic Toupet fundoplication. They were compared with 16 similar patients with poor esophageal body function who underwent Nissen fundoplication. The patients who underwent Toupet fundoplication had less dysphagia than those who had the Nissen procedure (9% vs. 44%;P=0.0041). Twenty-four-hour ambulatory pH monitoring and esophageal manometry were repeated in 31 Toupet patients 6 months after surgery. Percentage of time of esophageal exposure to pH <4.0, DeMeester reflux score, lower esophageal pressure, intra-abdominal length, vector volume, and distal esophageal amplitude all improved significantly after surgery. Ninety-one percent of patients were free of reflux symptoms. The laparoscopic Toupet fundoplication provides an effective antireflux barrier according to manometric, pH, and symptom criteria. It avoids potential postoperative dysphagia in patients with weak esophageal peristalsis and results teria. It avoids potential postoperative dysphagia in patients with weak esophageal peristalsis and results in improved esophageal body function 6 months after, surgery.

Prevalent esophageal body motility disorders underlie aggravation of GERD symptoms in morbidly obese patients following adjustable gastric banding

HYPOTHESIS: Preexisting gastroesophageal reflux disease (GERD) and esophageal motility disorders may affect the outcome of laparoscopic adjustable gastric banding (AGB). DESIGN: Prospective cohort study. SETTING: Tertiary referral center. PATIENTS: Between January 1, 1996, and December 31, 2002, AGB procedures were performed in 587 patients (mean body mass index, 46.7 [calculated as weight in kilograms divided by the square of height in meters]). The study population was composed of patients with preoperative GERD (assessed by a symptom-score questionnaire) and was divided into group 1 (those with preoperative GERD symptoms only) and group 2 (those with preoperative and postoperative GERD symptoms). INTERVENTIONS: Laparoscopic AGB was performed according to the pars-flaccida technique. MAIN OUTCOME MEASURES: All patients underwent preoperative and annual postoperative symptom scoring, endoscopy, esophageal barium swallow tests, esophageal manometry, and 24-hour pH monitoring. RESULTS: Mean follow-up time was 33 months (range, 12-49 months). A total of 164 patients (27.9%) were diagnosed as having preoperative GERD symptoms. In 112 (68.3%) of these patients GERD symptoms vanished postoperatively (group 1), whereas 52 patients (31.7%) remained symptomatic after undergoing laparoscopic AGB implantation (group 2). Preoperatively, group 2 patients showed significantly poorer esophageal body motility compared with group 1 patients (20.8% vs 12.8% defective propagations; P = .007). In group 2 the mean symptom scores for dysphagia (0.4 vs 0.9) and regurgitation (0.6 vs 1.4) deteriorated significantly following laparoscopic AGB implantation, respectively. Eighteen patients (34.6%) in group 2 developed esophageal dilatation. CONCLUSIONS: Adjustable gastric banding provides a sufficient antireflux barrier in most of the obese patients with GERD. However, in patients with preoperatively defective esophageal body motility, AGB may aggravate GERD symptoms and esophageal dilatation. Alternative bariatric surgical procedures should be considered in these patients.     

Preoperative Lower Esophageal Sphincter Manometry Data Neither Impact Manifestations of GERD nor Outcome After Laparoscopic Nissen Fundoplication

Background  Experience with laparoscopic antireflux surgery (LARS) in patients with gastroesophageal reflux disease (GERD) and manometrically intact lower esophageal sphincter (LES) is limited. The disease pattern may be different and LARS may fail to control reflux or result in higher rates of dysphagia. This is the first study investigating the impact of preoperative LES manometry data not only on manifestations of GERD and subjective outcome alone but also on objective outcomes 1 year after LARS. Methods  Three hundred fifty-one GERD patients underwent LARS and had subjective symptom and quality of life assessment, upper gastrointestinal endoscopy, barium swallow esophagogram, 24-h esophageal pH monitoring, and manometry pre- and 1 year postoperatively. Patients were divided into those with a preoperatively intact versus defective LES based on intraabdominal length and resting pressure. Baseline and 1-year postoperative follow-up data were compared. Results  Preoperative manifestations of GERD were similar in each group. Postoperatively, all symptoms except flatulence, quality of life scores, and objective manifestations improved significantly in each group. Conclusions  The preoperative manometric character of the LES neither impacts the manifestations of GERD nor subjective and objective outcomes after LARS. Patients with GERD and manometrically intact LES have no higher risk for postoperative dysphagia.     

Laparoscopic fundoplication: Nissen versus Toupet two-year outcome of a prospective randomized study of 200 patients regarding preoperative esophageal motility

Objective To determine the influence of preoperative esophageal motility on clinical and objective outcome of the Toupet or Nissen fundoplication and to evaluate the success rate of these procedures. Summary background data Nissen fundoplication (360°) is the standard operation in the surgical management of gastroesophageal reflux disease (GERD). In order to avoid postoperative dysphagia it has been proposed to tailor antireflux surgery according to pre-existing esophageal motility. Postoperative dysphagia is thought to occur more commonly in patients with esophageal dysmotility and it has been recommended to use the Toupet procedure (270°) in these patients. We performed a randomized trial to evaluate this tailored concept and to compare the two operative techniques concerning reflux control and complication rate (dysphagia). Methods 200 patients with GERD were included in a prospective, randomized study. After preoperative examinations (clinical interview, endoscopy, 24-hour pH-metry and esophageal manometry) 100 patients underwent either a laparoscopic Nissen procedure (50 with and 50 without motility disorders), or Toupet (50 with and 50 without motility disorders). Postoperative follow-up after two years included clinical interview, endoscopy, 24-hour pH-metry, and esophageal manometry. Results After two years 85% (Nissen) and 85% (Toupet) of patients were satisfied with the operative result. Dysphagia was more frequent following a Nissen fundoplication compared to Toupet (19 vs. 8, p < 0.05) and did not correlate with preoperative motility. Concerning reflux control the Toupet proved to be as good as the Nissen procedure. Conclusion Tailoring antireflux surgery according to the esophageal motility is not indicated, as motility disorders are not correlated with postoperative dysphagia. The Toupet procedure is the better operation as it has a lower rate of dysphagia and is as good as the Nissen fundoplication in controlling reflux.     

Laparoscopic Fundoplication in Patients with a Hypertensive Lower Esophageal Sphincter

Background  A small proportion of patients evaluated with manometry prior to a fundoplication have a high-pressure lower esophageal sphincter (LES). This paper examines the outcome of laparoscopic fundoplication for these patients. Material and Methods  Between October 1991 and December 2006, 1,886 patients underwent primary laparoscopic fundoplication. Those with a high-pressure LES on preoperative manometry (LESP ≥30 mm Hg at end expiration) were identified from a prospective database. Long-term outcomes were determined using analogue symptom scores (0–10) for heartburn, dysphagia, and patient satisfaction and compared to those of a matched control group. Results  Thirty patients (1.6%), nine men and 21 women, median age 51 years, had a hypertensive LES (mean, 36 mmHg; range, 30–55). Median follow-up after fundoplication was 99 (12–182) months. These patients had similar mean symptom scores to 30 matched controls for heartburn (2.3 vs. 2.2, P = 0.541), dysphagia (2.7 vs. 3.1, P = 0.539), and satisfaction (7.4 vs. 7.6, P = 0.546). Five patients required revision for dysphagia compared to no control patients (P = 0.005). These patients had a higher preoperative dysphagia score (6.6 vs. 3.1, P = 0.036). Conclusion  Laparoscopic fundoplication can be performed with good long-term results for patients with reflux and a hypertensive LES. However, those with preoperative dysphagia have a higher failure rate.     

Laparoscopic fundoplication for dysphagia and peptic esophageal stricture

Peptic esophageal stricture with dysphagia is a late manifestation of severe gastroesophageal reflux disease (GERD). Although laparoscopic fundoplication is an effective antireflux operation, its efficacy for persons with peptic esophageal stricture and dysphagia has not been well defined. The aim of this study was to evaluate outcomes after fundoplication in this subgroup of GERD patients. Forty GERD patients with moderate, severe, or incapacitating dysphagia and peptic esophageal stricture were compared to a control group of 121 GERD patients without significant dysphagia or stricture. Reflux symptom severity was scored by each patient preoperatively and at most recent follow-up postoperatively (mean 1.5 years) using a scale ranging from 0 to 4 (0 = symptoms absent; 4 = symptoms incapacitating). Symptom scores were compared by the Wilcoxon rank-sum test. Postoperative redilation and fundoplication failure rates were also determined. At a mean follow-up of 1.5 years after fundoplication, the median dysphagia score had improved from 3 to 0 (P <0.001) in stricture patients and remained low (score 0) in the control group. The median heartburn score also improved from 3 to 0 (P <0.001) in stricture patients, with an identical response in the control group (P <0.001). Among dysphagia/stricture patients, 35 (87.5%) reported overall satisfaction and have not required secondary medical treatment or esophageal dilation. Four patients (10%) have required endoscopic redilation for residual dysphagia and one (2.5%) had re-operation for fundoplication herniation shortly after operation. Laparoscopic fundoplication is an effective therapy for patients with dysphagia and peptic esophageal stricture.

Laparoscopic antireflux surgery in the elderly

Background: Laparoscopic antireflux surgery is frequently denied to older patients with gastroesophageal reflux disease (GERD) because of a perceived higher operative complication rate, a decreased impact of the intervention on quality of life, and decreased cost effectiveness. This study compares disease severity, surgical outcomes, and impact on quality of life between elderly and young patients with GERD. Methods: Patients were selected from a prospectively maintained database of 1100 patients who underwent various laparoscopic esophageal procedures at our institution. Only patients having chronic intractable GERD and a minimum 6 months' follow-up were included in the study. Thirty elderly patients with a mean age of 71.2 years (SD ± 5.6) were compared with a group of 30 younger patients (mean age, 43.9 ± 12.8 years). Comparisons were made between subjective and objective outcomes, operative results, and health-related quality of life (HQRL) scores using SF-36 instruments. Results: The preoperative symptom assessment scores (representing frequency of symptoms on a 0-4 scale), and preoperative pH and manometry data were comparable in the two groups. Elderly patients had significantly higher ASA (American Society of Anesthesiologists) scores. Each group demonstrated a significant improvement in the postoperative symptom assessment scores and the esophageal functional studies (p<0.05). However, no significant differences were found in terms of postoperative complications, postoperative hospital stay, postoperative symptom scores, Demeester scores, or the HRQL data. Conclusion: Laparoscopic antireflux surgery in elderly patients improves acid reflux and appears to be safe and effective as measured by postoperative testing in elderly and young patients.     

Effectiveness of laparoscopic fundoplication in relieving the symptoms of gastroesophageal reflux disease (GERD) and eliminating antireflux medical therapy

Background: Recent reports have suggested that antireflux surgery should not be advised with the expectation of elimination of medical treatment. We reviewed our results with laparoscopic fundoplication as a means of eliminating the symptoms of gastroesophageal reflux disease (GERD), improving quality of life, and freeing patients from chronic medical treatment for GERD. Methods: A total of 297 patients who underwent laparoscopic fundoplication (Nissen, n = 252; Toupet, n = 45) were followed for an average of 31.4 months. Preoperative evaluation included endoscopy, barium esophagram, esophageal manometry, and 24-h pH analysis. A preoperative and postoperative visual analogue scoring scale (0–10 severity) was used to evaluate symptoms of heartburn, regurgitation, and dysphagia. A GERD score (2–32) as described by Jamieson was also utilized. The need for GERD medications before and after surgery was assessed. Results: At 2-year follow-up, the average symptom scores decreased significantly in comparison to the preoperative values: heartburn from 8.4 to 1.7, regurgitation from 7.2 to 0.7, and dysphagia from 3.7 to 1.0. The Jamieson GERD score also decreased from 25.7 preoperatively to 4.1 postoperatively. Only 10% of patients were on proton pump inhibitors (PPI) at 2 years after surgery for typical GERD symptoms. A similar percentage of patients (8.7%) were on PPI treatment for questionable reasons, such as Barretts esophagus, sensitive stomach, and irritable bowel syndrome. Seventeen patients (5.7%) required repeat fundoplication for heartburn (n = 9), dysphagia (n = 5), and gas/bloating (n = 3). Conclusions: Laparoscopic fundoplication can successfully eliminate GERD symptoms and improve quality of life. Significant reduction in the need for chronic GERD medical treatment 2 years after antireflux surgery can be anticipated.

The outcome of laparoscopic antireflux surgery in relation to patients' subjective degree of compliance with former antireflux medication

It is well known that several patient-related factors are able to affect the surgical outcome such as quality of life or symptom relief after laparoscopic antireflux surgery. The aim of the current study was to evaluate and compare surgical outcome up to 1 year after laparoscopic antireflux surgery in relation to patients' subjective degree of compliance with former antireflux medication. Based on a three-level grading of subjective compliance with primary antireflux medication, a total of 140 patients undergoing antireflux surgery were divided into three subgroups: group 1/TC (totally compliant; n = 60), group 2/PC (partially compliant; n = 49); and group 3/NC (noncompliant; n = 31). Gastrointestinal Quality of Life Index (GIQLI), satisfaction with surgery, and the subjective degree of dysphagia as well as traditional outcome data (e.g., DeMeester score, lower esophageal sphincter pressure, side effects) were evaluated in all patients. As a result of surgery, only patients out of group 1/TC (GIQLI, preoperative 86.3 + 9.3 vs. 1 year postoperatively 123.1 + 7.2 points) and group 2/PC (GIQLI, preoperative 94.2 + 8.6 vs. 1 year postoperatively 120.8 + 7.8 points) showed a significant quality of life improvement that remained stable for at least 1 year (P < 0.05-0.01). In contrast, group 3/NC (GIQLI, preoperative 100.2 + 6.1 vs. 1 year postoperatively 117.2 + 9.8 points) patients had no significant quality of life improvement and patient satisfaction with surgery was less good when compared with that of the other groups. In these patients, also the subjective degree of postoperative dysphagia was significantly (P < 0.05-0.001) higher during the 1-year follow-up when compared with patients from group 1/TC or group 2/PC. A total of 42% of group 3/NC patients reported surgical side effects, whereas only 3% from group 1/TC and 10% from group 2/PC stated to be affected by any new symptoms (P < 0.0001). None of group 1/TC or group 2/PC patients suffered from recurrent symptoms or underwent laparoscopic reoperation. Of group 3/NC, a total of four patients (13%) needed any kind of additional intervention in relation to antireflux surgery (reoperation, n = 3; pneumatic dilatation, n = 1). There were no significant differences between the three groups when postoperative values of esophageal manometry and 24-hour pH monitoring were compared. What the current study does show is that the efficacy and the surgical outcome after laparoscopic antireflux surgery partly depends on the subjective degree of patient compliance with primary antireflux medication. Patients with no compliance in relation to former antireflux medication should generally not be refused antireflux surgery. But these patients should be evaluated with great care before surgery and should also be informed that surgical outcome may be affected in several aspects.     

Nissen vs toupet laparoscopic fundoplication

BACKGROUND: Nissen fundoplication (360 degrees ) is the standard operation for the surgical management of gastroesophageal reflux disease (GERD). To avoid postoperative dysphagia, it has been proposed that antireflux surgery be tailored according to the degree of preexisting esophageal motility. Postoperative dysphagia is thought to occur more commonly in patients with esophageal dysmotility and the Toupet procedure (270 degrees ) has been recommended for these patients. We performed a randomized trial to evaluate this tailored concept and to compare the two operative techniques in terms of reflux control and complication rate (dysphagia). Our objective was to determine the impact of preoperative esophageal motility on the clinical and objective outcome, following Toupet vs Nissen fundoplication and to evaluate the success rate of these procedures. METHODS: From May 1999 until May 2000, 200 patients with GERD were included in a prospective randomized study. After preoperative examinations (clinical interview, endoscopy, 24-h pH study and esophageal manometry), 100 patients underwent either a laparoscopic Nissen (50 with and 50 without motility disorders), or a Toupet procedure (50 with and 50 without motility disorders). Postoperative follow-up after 4 months included clinical interview, endoscopy, 24-h pH study and esophageal manometry. RESULTS: Interviews showed that 88% (Nissen) and 90% (Toupet) of the patients, respectively, were satisfied with the operative result. Dysphagia was more frequent following a Nissen fundoplication than after a Toupet (30 vs 11, p <0.001) and did not correlate with preoperative motility. In terms of reflux control, the Toupet proved to be as effective as the Nissen procedure. CONCLUSION: Tailoring antireflux surgery to esophageal motility is not indicated, since motility disorders are not correlated with postoperative dysphagia. The Toupet procedure is the better operation because it has a lower rate of dysphagia and is as effective as the Nissen fundoplication in controlling reflux.     

Use of Endoluminal Antireflux Therapies for Obese Patients with GERD

Background  Obese patients with gastroesophageal reflux disease (GERD) refractory to medical therapy are a challenging patient population as obesity is a preoperative predictor of failure after antireflux surgery. We therefore sought to evaluate outcomes using one of two commercially available endoluminal therapies in this population. Methods  Consecutive obese patients (body mass index (BMI) > 30) with GERD (DeMeester >14.5) undergoing either Plicator (NDO) or Stretta (Curon) were identified in our single-institution prospective database. Outcomes assessed were: (1) failure rate (absolutely no symptomatic improvement after procedure and/or need for subsequent antireflux surgery), (2) postoperative vs. preoperative symptom (heartburn, chest pain, regurgitation, dysphagia, cough, hoarseness, and asthma) scores, and (3) proton-pump inhibitor (PPI) medication use. Results  Twenty-two patients each underwent an endoluminal therapy (ten Plicator patients and 12 Stretta patients) with mean follow-up of 1.5 years. There were no treatment-associated complications. Mean BMI was not different between Plicator and Stretta groups (39.6 vs. 38.6, respectively, p = 0.33). The failure rate for the entire cohort was 28% (10% Plicator vs. 42% Stretta, p = 0.11). The proportion of patients reporting moderate/severe symptoms postop was significantly less than preop: chest pain 9% vs. 13% (p = 0.04), cough 22% vs. 36% preop (p = 0.025), voice changes 9% vs. 36% preop (p = 0.012), and dysphagia 9% vs. 32% preop (p = 0.04). The proportion of patients on PPI medications postop was also less than preop (45% vs. 81%, p = 0.1) Conclusion  Endoluminal treatment can provide a safe means of improving GERD symptoms for some obese patients, though many will continue to require medication therapy also. Further work aimed at understanding optimal candidates for endoluminal therapy in this patient population is warranted.     

Prospective Study Examining the Impact of Multichannel Intraluminal Impedance on Antireflux Surgery

Background Reflux monitoring using combined multichannel intraluminal impedance (MII) and pH-metry increases the sensitivity for identifying gastroesophageal reflux episodes. The likelihood of a positive symptom index (SI) for patients with reflux disease (gastroesophageal reflux disease [GERD] or nonerosive reflux disease [NERD]) receiving proton pump inhibitor (PPI) treatment has been used to select candidates for antireflux surgery. Little is known about the advantages of MII-pH monitoring compared with pH monitoring alone for evaluating GERD/NERD patients off PPI treatment considered as candidates for antireflux surgery or for assessing changes in MII-pH-detected reflux episodes after antireflux surgery. This study aimed to determine the additional value of MII over pH-metry alone for patients off PPI treatment before and after antireflux surgery. Methods For this study 12 patients (4 women and 8 men; mean age, 45 years; range, 27–74 years) were evaluated using ambulatory MII-pH monitoring before and 3 months after mesh-augmented hiatoplasty. Reflux events were identified by MII-pH (A) and pH-metry (B) as patients recorded symptoms on a data logger. For each symptom, a symptom index was calculated for reflux events identified by MII-pH and by pH-monitoring alone. Results Preoperatively, MII-pH monitoring identified 71.9 ± 8.4 reflux episodes, whereas pH monitoring identified only 51.0 ± 7.8 (p < 0.05). Postoperatively, MII-pH monitoring identified 35.5 ± 6.6 reflux episodes, whereas pH monitoring identified only 19.6 ± 4.7 (p < 0.05). The pre- and postoperative symptom index for MII-pH monitoring was higher than pH monitoring (preoperative 91.7% vs 25%, p = 0.006; postoperative 50% vs 16.7%, p = 0.012). Conclusion Combined MII-pH-metry improves the pre- and postoperative assessment of GERD patients off PPI and results in a higher symptom-reflux association.     

Clinical outcomes after laparoscopic antireflux surgery in patients with and without preoperative endoscopic esophagitis

A wide spectrum of endoscopic findings exists in patients with gastroesophageal reflux disease (GERD). This study compared clinical outcomes after laparoscopic antireflux surgery (LARS) in patients who had GERD with and without preoperative endoscopic esophagitis. From 1992 to 2001, a total of 414 patients who underwent LARS with 6 months or more of follow-up were prospectively entered into a database. Among these patients, 84 (20%) had no endoscopic evidence of esophagitis on preoperative endoscopy (group 1), whereas 330 (80%) did have esophagitis (group 2). Perioperative outcomes, GERD symptom relief, and the use of acid-reducing medication were assessed. Preoperative DeMeester scores in groups 1 and 2 were 44 ± 29 and 61 ± 62 (P < 0.05) and mean esophageal peristaltic amplitude was 86 ± 32 mm Hg vs. 60 ± 42 mm Hg, respectively (P < 0.05). Although procedure time was significantly shorter in group 1, other perioperative outcomes were similar. At postoperative follow-up, the use of proton pump inhibitors was reduced in both groups (86% to ≤14%). With the exception of postoperative dysphagia, there was no difference in GERD symptom relief between groups 1 and 2. The presence or absence of preoperative esophagitis has minimal effect on favorable symptomatic outcomes after LARS. Thus LARS is an effective treatment option for patients, irrespective of endoscopic evidence of esophagitis, leading to excellent symptom relief and a marked reduction in the use of proton pump inhibitors.

The value of multiple rapid swallows during preoperative esophageal manometry before laparoscopic antireflux surgery

Background

When multiple swallows are rapidly administered, esophageal peristalsis is inhibited, and pronounced lower esophageal sphincter relaxation ensues. After the last swallow of the series, a robust contraction sequence results. The authors hypothesize that multiple rapid swallows (MRS) may have value in predicting esophageal transit symptoms in patients undergoing laparoscopic antireflux surgery (LARS).

Methods

Records of patients undergoing esophageal high-resolution manometry (HRM) before LARS were evaluated. The evaluation of MRS included adequate inhibitory response during swallows and the contraction pattern after MRS. Dysphagia was scored based on a product of symptom frequency and severity using 5-point Likert scales. A composite dysphagia score comprised the sum of scores for solid and liquid dysphagia, and a score of 4 or higher was considered clinically significant. The normal and abnormal MRS responses of patients with preoperative, early, and late postoperative dysphagia were compared with those of patients with no dysphagia.

Results

In this study, 63 patients (mean age, 60.3?±?1.7?years, 48 women) undergoing HRM before LARS successfully performed MRS (median, 5 swallows; longest interval between swallows, 3.2?±?0.1?s). After MRS, 14 patients (22.2?%) had an intact peristaltic sequence. Complete failure of peristalsis was seen in 21 (33.3?%), and incomplete esophageal inhibition in 25 (39.7?%) of the remaining patients. When stratified by presence or absence of dysphagia, 58.3?% of the subjects without dysphagia had a normal MRS response, whereas 83.3?% had formation of peristaltic segments after MRS. In contrast, only 14?% of the subjects with dysphagia had a normal MRS response (p????0.003 vs. the subjects with no dysphagia). Abnormal MRS responses were more prevalent in the patients with any preoperative and late postoperative dysphagia (p?=?0.04 across groups) and in those with clinically significant dysphagia (p?=?0.08 across groups).

Conclusions

High-resolution manometry with MRS helps to predict dysphagia in subjects undergoing preoperative esophageal function testing before LARS.     

Laparoscopic Nissen fundoplication with prosthetic hiatal closure reduces postoperative intrathoracic wrap herniation: preliminary results of a prospective randomized functional and clinical study

BACKGROUND: Postoperative intrathoracic wrap migration is the most frequent morphological complication after laparoscopic antireflux surgery. Previous authors have studied the use of prosthetic materials for hiatal closure to prevent recurrence of hiatal hernia and/or postoperative intrathoracic wrap herniation. HYPOTHESIS: Patients with prosthetic hiatal closure have a higher rate of short-term dysphagia but a significantly lower rate of postoperative intrathoracic wrap herniation at follow-up. DESIGN: Prospective randomized trial. We compared patients who underwent laparoscopic Nissen fundoplication with simple sutured hiatoplasty with those who underwent laparoscopic Nissen fundoplication with prosthetic hiatal closure. SETTING: University-affiliated community hospital. PATIENTS: One hundred consecutive patients undergoing laparoscopic Nissen fundoplication for gastroesophageal reflux disease and hiatal hernia repair. INTERVENTION: Laparoscopic Nissen fundoplication with simple sutured crural closure (n = 50 [group 1]) vs laparoscopic Nissen fundoplication with simple sutured cruroplasty and onlay of a polypropylene mesh (n = 50 [group 2]). MAIN OUTCOME MEASURES: Recurrences; complications; results of esophageal manometry, 24-hour pH monitoring, esophagogastroduodenoscopy, and barium swallow test; and symptomatic outcome. RESULTS: Patients in both groups had similar preoperative values in esophageal manometry, 24-hour pH monitoring, and symptom scoring. At the 3-month and 1-year follow-ups, functional outcome variables (lower esophageal sphincter pressure and DeMeester score) improved significantly compared with the preoperative values. A higher postoperative dysphagia rate could be evaluated in group 2. An intrathoracic wrap migration occurred in 13 patients (26%) in group 1 vs 4 (8%) in group 2 (P<.001). CONCLUSION: Laparoscopic Nissen fundoplication with prosthetic cruroplasty is an effective procedure to reduce the incidence of postoperative hiatal hernia recurrence and intrathoracic wrap herniation.     

Does major depression in patients with gastroesophageal reflux disease affect the outcome of laparoscopic antireflux surgery?

Background: It is known that psychological factors can affect end points of surgical treatment. The current study aimed to evaluate the outcome of laparoscopic antireflux surgery (LARS) in patients with gastroesophageal reflux disease (GERD) who experience concomitant major depression in comparison with GERD patients who have no known comorbidity. Methods: Among a sample of more than 550 patients who underwent LARS, a group of 38 GERD patients with concomitant major depression (MD) were included in this study. The patients included 24 women and 14 men, with a mean age of 51 years. A group of 38 control patients (non-MD) matched in terms of age, gender, and esophageal manometry findings was selected from the database for comparison of surgical outcomes between patients with GERD accompanied by concomitant major depression and GERD patients with no known comorbidity. In each group, 23 patients received a Toupet fundoplication and 15 patients underwent a "floppy" Nissen fundoplication. The following factors were evaluated before surgery, 3 months afterward, and 1 year after LARS: symptoms (heartburn, regurgitation, chest pain, bloating, and dysphagia), quality of life (Gastrointestinal Quality of Life Index [GIQLI]), lower esophageal sphincter pressure (LESP), and 24-h pH monitoring (DeMeester score). Results: Before and after surgery, there were no significant differences between the two groups in terms of LESP and DeMeester score. Preoperative GIQLI showed significant differences (p < 0.05) between the two groups (MD group, 71.8 ± 8.6 vs non-MD group, 91.1 ± 9.8), and significant differences (p < 0.01–0.001) between the mean data and that for healthy individuals (122.6 ± 8.5). The GIQLI scores had improved significantly at 3 months and at 1 year after surgery (p < 0.05–0.001) in all the patients (1 year postoperatively: MD group, 99.3 ± 8.6 vs non-MD group, 121.9 ± 9.7). Before surgery, when symptoms were compared between the two groups, significant differences (p < 0.001) were found in the percentage of chest pain (81.6% vs 37.4%) and bloating (92.2% vs 37.4%), showing that these symptoms were more predominant and graded as much more severe among patients with MD. In both groups, all the symptoms but dysphagia showed a significant improvement in severity (p < 0.05–0.0001). A comparison of both groups postoperatively showed that significant differences were still present in chest pain (44.7% vs 2.6%), bloating (68.4% vs 18.4), and dysphagia (50.1% vs 2.6%). A significant difference (p < 0.001) was observed only in patients with major depression and depending on the kind of wrap procedure (Nissen vs Toupet), showing that dysphagia (78.9% vs 21.1%) and chest pain (82.4% vs 17.6%) were much more predominant in patients who underwent "floppy" Nissen fundoplication. Conclusions: Even if they are good surgical candidates from a physiologic point of view, GERD patients with concomitant major depression should be selected carefully. In these patients, LARS can normalize physiologic data, but some patients have demonstrated less symptomatic relief, suffered from postoperative dysphagia, and showed less quality-of-life improvement. Eventually, laparoscopic Toupet fundoplication used with these patients could result in a better subjective outcome.     

Postoperative esophageal physiology studies may help to predict long-term symptoms following laparoscopic Nissen fundoplication

Background Laparoscopic Nissen fundoplication is an established treatment for gastroesophageal reflux disease (GERD). Postoperative improvement in esophageal physiology can be indicative of successful surgery, but the degree to which it correlates with symptom control remains questionable. We have performed this study to assess the utility of postoperative esophageal physiology studies in predicting long-term symptomatic outcome. Methods Between August 1997 and August 2003, 145 patients with symptomatic GERD underwent laparoscopic Nissen fundoplication as part of a randomized trial. Four months after surgery patients were invited to have postoperative esophageal physiology studies. In November 2005, a postal questionnaire was sent to all patients in order to assess reflux symptomatology (DeMeester symptom score). Results Completed symptom questionnaires were returned by 108 patients (74%) after a median of 5.7 years postoperatively. Linear regression of manometry data showed a significant correlation between the level of postoperative neosphincter pressure either above or below the median and long-term scores for heartburn (p = 0.03), dysphagia (p = 0.02), regurgitation (p = 0.01), and total symptom score (p = 0.002). In contrast, there was no evidence of a significant correlation between results of postoperative esophageal pH studies and symptom scores. Conclusion Postoperative physiology studies, particularly manometry, may be predictive of long-term symptoms following laparoscopic Nissen fundoplication.

Factors predictive of dysphagia after laparoscopic Nissen fundoplication

Background: Persistent postoperative dysphagia occurs in up to 24% of patients who undergo a laparoscopic Nissen fundoplication for reflux disease [7]. We hypothesized that patient history, pH testing, and esophageal manometry could be used to preoperatively identify patients at risk for this complication. Methods: Of 156 laparoscopic Nissen fundoplications performed over a 27-month period, we identified 19 patients (12%) who suffered from postoperative dysphagia longer than 3 months. The presenting complaint of preoperative swallowing difficulty was noted as was the presence of a known esophageal stricture. Preoperative pH testing and esophageal manometry were performed for all subjects. We compared the following parameters to an age and gender-matched control group: history of esophageal stricture, presence of preoperative dysphagia, DeMeester reflux score, upper esophageal sphincter pressure and relaxation, esophageal body motility, location of respiratory inversion point, and lower esophageal sphincter length, resting pressure, and relaxation. Data were compared via t-test and Fisher's exact test. Results: Patients who presented before surgery with complaints of difficulty swallowing were more likely to suffer from postoperative dysphagia (p= 0.029). Incidence of stricture, DeMeester score, and manometric measurements did not differ between the dysphagia and control groups (p > 0.05 for all parameters). Conclusions: Although preoperative studies are not helpful in identifying patients at risk for persistent dysphagia after laparoscopic Nissen fundoplication, patients presenting with the preoperative complaint of difficulty swallowing are at increased risk for this complication.

Obesity is not a contraindication to laparoscopic nissen fundoplication

Obesity has been shown to be a significant predisposing factor for gastroesophageal reflux disease (GERD). However, obesity is also thought to be a contraindication to antireflux surgery. This study was undertaken to determine if clinical outcomes after laparoscopic Nissen fundoplications are influenced by preoperative body mass index (BMI). From a prospective database of patients undergoing treatment for GERD, 257 consecutive patients undergoing laparoscopic Nissen fundoplication were studied. Patients were stratified by preoperative BMI: normal (<25), overweight (25-30), and obese (>30). Clinical outcomes were scored by patients with a Likert scale. Overweight and obese patients had more severe preoperative reflux, although symptom scores for reflux and dysphagia were similar among all weight categories. There was a trend toward longer operative times for obese patients. Mean follow-up was 26 ± 23.9 months. Mean heartburn and dysphagia symptom scores improved for patients of all BMI categories (P < 0.001). Postoperative symptom scores and clinical success rates did not differ among BMI categories. Most patients undergoing laparoscopic Nissen fundoplication are overweight or obese with moderate dysphagia and severe acid reflux. Clinical outcomes after laparoscopic Nissen fundoplication did not differ among patients stratified by preoperative BMI. Obesity is not a contraindication to laparoscopic Nissen fundoplication.

Laparoscopic antireflux surgery for the elderly: A surgical and quality-of-life study

Purpose Laparoscopic antireflux surgery (LARS) has long been introduced as an alternative method for the treatment of gastroesophageal reflux disease (GERD) in young adults. However, the safety of this procedure and the associated improvement in the quality of life for the elderly are rarely discussed. This study compared the results between young and elderly patients who underwent laparoscopic fundoplication for the treatment of GERD. Methods From January 1999 to January 2006, there were 231 adult patients who underwent LARS for GERD at a single institute. Among all patients, 33 patients were older than 70 years old (14.3%, 73.0 ± 1.9, range 70–76), 198 patients were younger than 70 years old (85.7%, 46.6 ± 11.5, range 20–69). The clinical characteristics, operation time, postoperative hospital stay, surgical complications, and quality of life were retrospectively analyzed. Results The mean operation time had no significant difference between the younger group and the elderly group. The mean postoperative hospital stay in the elderly group was slightly longer than the younger group (4.1 ± 2.5 days vs 3.4 ± 1.3 days, P = 0.19). There were no mortalities and no major complications found in each group. No patients required conversion to an open procedure. Four patients had minor complications (three in the elderly group, rate: 9.0%; one in the younger group, rate: 0.5%, P < 0.05). There were two patients in the nonelderly group who had recurrence. A comparison of the preoperative and postoperative Gastro-Intestinal Quality of Life Index (GIQLI) scores showed significant improvements (99.3 ± 19.2 points, and 110.2 ± 20.6 points, respectively, P < 0.05) with no significant difference between the two groups. Conclusion Laparoscopic antireflux surgery thus appears to provide an equivalent degree of safety and symptomatic relief for elderly patients with GERD as that observed in young patients.
