Heartburn is more likely to recur after Toupet fundoplication than Nissen fundoplication

Toupet (270 degrees) fundoplication is commonly recommended for patients with gastroesophageal reflux (GER) and esophageal dysmotility. However, Toupet fundoplication may be less effective at protecting against reflux than Nissen (360 degrees) fundoplication. We therefore compared the effectiveness and durability of both types of fundoplication as a function of preoperative esophageal motility. From January 1992 through January 1998, 669 patients with GER underwent laparoscopic fundoplication (78 Toupet, 591 Nissen). Patients scored heartburn, regurgitation, and dysphagia preoperatively, and at 6 weeks and 1 year postoperatively, using a 0 ("none") to 3 ("severe") scale. We compared symptom scores (Wilcoxon rank sum test) and redo fundoplication rates (Fisher exact test) in Toupet and Nissen patients. We also performed subgroup analyses on 81 patients with impaired esophageal motility (mean peristaltic amplitude, <30 mm Hg or peristalsis <70% of wet swallows) and 588 patients with normal esophageal motility. Toupet and Nissen patients reported similar preoperative heartburn, regurgitation, and dysphagia. At 6 weeks after operation, heartburn and regurgitation were similarly improved in both groups, but dysphagia was more prevalent among Nissen patients. After 1 year, heartburn and regurgitation were re-emerging in Toupet patients, and dysphagia was again similar between groups. Patients with impaired motility who have Nissen fundoplication are no more likely to suffer persistent dysphagia than their counterparts who have Toupet fundoplication. In addition, patients with normal motility are more likely to develop symptom recurrence after Toupet fundoplication than Nissen fundoplication, with no distinction in dysphagia rates. We conclude that since Toupet patients suffer more heartburn recurrence than Nissen patients, with similar dysphagia, selective use of Toupet fundoplication requires further study.     

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.     

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.     

Complete fundoplication has similar long-term results in patients with and without esophageal body dysmotility

Background: Partial fundoplication is advocated for the treatment of gastroesophageal reflux disease in patients with poor esophageal body function. We hypothesized that a complete floppy wrap may be just as safe in patients with poor esophageal motility. Methods: A retrospective, case-control study was performed on patients who underwent a complete fundoplication and had poor esophageal motility. Study patients were matched with controls with normal esophageal body pressures according to sex, age, and duration of reflux symptoms. Patients were followed up and interviewed using a modified symptom and life quality questionnaire. Results: Twenty-two patients and 22 matched controls underwent a complete fundoplication. The mean esophageal body pressure was 42.1 and 87.5 mmHg in the study and control groups, respectively (p <0.05). Average time to resolution of dysphagia was 10.1 weeks in the study group and 12 weeks in the control group. All patients but 1 (control) graded their life quality improvement as good to excellent. Conclusion: Our data suggest that a 360° fundoplication has similar long-term results regardless of esophageal body motility. We suggest that a partial fundoplication may be reserved for patients with severe esophageal body dysfunction. The role of manometry in the preoperative workup should be reassesed: it may be mandatory only in patients with preoperative dysphagia or when achalasia is suspected.     

Techniques and outcomes of laparoscopic surgery in gastroesophageal reflux disease

BACKGROUND: The purpose of this study is to report personal experience in laparoscopic antireflux surgery and to analyze the clinical and functional outcomes of this procedure, also in relation to the different techniques used. METHODS: From 1996 to 2000, 20 patients with gastroesophageal reflux disease associated with hiatal hernia underwent laparoscopic surgery. The indication for surgery was failure of long-term medical therapy. All patients had severe acid reflux on 24 hrs-pH monitoring, endoscopic evidence of esophagitis and hiatal hernia, and defective lower esophageal sphincter. A Nissen fundoplication was performed in 13 patients with normal esophageal body motility, and a 270 degrees posterior fundoplication in seven patients with low esophageal motility. RESULTS: Mortality and conversion rate were 0. Mean operative time was 135 min and mean postoperative hospital stay 5 days. Operative morbidity was 15%. All the patients were completely cured of reflux symptoms; transient mild postoperative dysphagia occurred in two patients (10%). There was a significantly improvement of the results in postoperative esophageal manometry and 24 hrs-pH monitoring. CONCLUSIONS: This preliminary experience suggests that laparoscopic surgery represents a safe and effective procedure for the treatment of gastroesophageal reflux disease. Precise selection of patients and adequate surgical technique are essential.     

Selective use of esophageal manometry and 24-Hour pH monitoring before laparoscopic fundoplication

BACKGROUND: Preoperative esophageal manometry and 24-hour pH monitoring commonly are used in preoperative evaluation of patients undergoing fundoplication. Here we review our experience with the selective preoperative workup of patients undergoing fundoplication to treat gastroesophageal reflux disease. STUDY DESIGN: A series of 628 consecutive antireflux procedures was reviewed. History and physical examination, upper endoscopy, and upper gastrointestinal videofluoroscopy were obtained preoperatively on all patients; the first 30 patients also underwent esophageal manometry and pH monitoring (routine evaluation group). Thereafter, pH monitoring only was performed for atypical reflux symptoms, and manometry only was performed for a history of dysphagia, odynophagia, or for abnormal motility on videofluoroscopy (selective evaluation group). All patients underwent a laparoscopic floppy Nissen fundoplication, and then endoscopy and fluoroscopy at 3 months and 12 months postoperatively. RESULTS: Eighty-five of the patients in the selective evaluation group (14%) required manometry, and 88 (15%) underwent pH monitoring. Eighteen of the 115 patients who underwent manometry (16%) had evidence of dysmotility. None of these 18 patients had increased dysphagia postoperatively; 8 of 18 reported improvement with swallowing. Five patients in the selective group (0.8%) had persistent postoperative dysphagia caused by technical error (four patients) or with no identifiable cause (one patient). The estimated charge or collection reduction with use of the selective evaluation was 1,253,100 US dollars or 395,000 US dollars, respectively. CONCLUSIONS: Selective use of manometry and pH monitoring was cost effective and safe in this series. Although esophageal manometry and 24-hour pH monitoring might be necessary with abnormal findings on videofluoroscopy or atypical symptoms, in our experience, their routine use is not essential in preoperative evaluation of patients undergoing fundoplication for gastroesophageal reflux disease.     

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.

Acid normalization and improved esophageal motility after Nissen fundoplication: equivalent outcomes in patients with normal and ineffective esophageal motility

BACKGROUND: Severe gastroesophageal reflux disease may result in acquired esophageal dysmotility. The correct surgical approach to associated gastroesophageal reflux disease and dysmotility is controversial, in particular whether the "gold-standard" total fundoplication of Nissen is appropriate compared with partial fundoplication. Our unit has performed total fundoplication for all patients, irrespective of esophageal motility, and this article describes that experience. METHODS: Ninety-eight patients undergoing antireflux surgery were divided into 2 groups. Group 1 (n=60) consisted of patients with normal esophageal motility, and group 2 (n=38) had dysmotility. All patients underwent preoperative and postoperative manometry, 24-hour pH testing, symptom scoring, and quality-of-life assessment. RESULTS: The median postoperative acid score was not significantly different between groups 1 and 2. Eighty-eight percent of patients with normal motility and 89% of patients with dysmotility had no symptoms or minor symptoms, with a significant improvement in quality of life 6 months after surgery. There was a significant increase in esophageal wave amplitude in both groups, and 20 patients (53%) in the dysmotility group reverted to normal motility after surgery. Recurrent symptoms were associated with postoperative abnormal pH profiles in 5 patients from group 1 and 3 from group 2. CONCLUSIONS: Preoperative dysmotility is not a contraindication for total fundoplication. Postoperative acid control is associated with improved esophageal clearance and symptoms.     

Complete fundoplication is not associated with increased dysphagia in patients with abnormal esophageal motility

Abnormal esophageal motility is a relative contraindication to complete (360-degree) fundoplication because of a purported risk of postoperative dysphagia. Partial fimdoplication, however, may be associated with increased postoperative esophageal acid exposure. Our aim was to determine if complete fundoplication is associated with increased postoperative dysphagia in patients with abnormal esophageal motor function. Medical records of 140 patients (79 females; mean age 48 ±1.1 years) who underwent fundoplication for gastroesophageal reflux disease (GERD) were reviewed retrospectively to document demographic data, symptoms, and diagnostic test results. Of the 126 patients who underwent complete fundoplication, 25 met manometric criteria for abnormal esophageal motility (≤30 mm Hg mean distal esophageal body pressure or ≤80% peristalsis), 68 had normal esophageal function, and 33 had incomplete manometric data and were therefore excluded from analysis. Of the 11 patients who underwent partial fundoplication, eight met criteria for abnormal esophageal motility, two had normal esophageal function, and one had incomplete data and was therefore excluded. After a median follow-up of 2 years (range 0.5 to 5 years), patients were asked to report heartburn, difficulty swallowing, and overall satisfaction using a standardized scoring scale. Complete responses were obtained in 72%. Sixty-five patients who underwent complete fundoplication and had manometric data available responded (46 normal manometry; 19 abnormal manometry). Outcomes were compared using the Mann-Whitney U test. After complete fundoplication, similar postoperative heartburn, swallowing, and overall satisfaction were reported by patients with normal and abnormal esophageal motility. Likewise, similar outcomes were reported after partial fundoplication. This retrospective study found equally low dysphagia rates regardless of baseline esophageal motility; therefore a randomized trial comparing complete versus partial fundoplication in patients with abnormal esophageal motility is warranted.

Laparoscopic hiatal hernia repair in patients with poor esophageal motility or paraesophageal herniation

Laparoscopic repair for gastroesophageal reflux disease is now an accepted therapy. However, controversy exists with regard to the choice of operation between complete 360-degree Nissen fundoplication versus partial 270-degree Toupe fundoplication. In addition there is some controversy with regard to the proper choice of operation in patients with poor esophageal motility. Another class of hiatal hernia patients are those patients with paraesophageal herniation. Questions regarding the approach to these patients include whether or not to use a reflux procedure at the time of repair and the role of mesh in repair of these large hernias. This retrospective study was undertaken to compare the results of laparoscopic Nissen fundoplication and Toupe fundoplication in patients with both normal and abnormal esophageal motility. In addition the subset of patients with paraesophageal herniation was studied in an effort to ascertain the best surgical approach in these patients. In this study a retrospective analysis was performed on 188 consecutive patients during the period 1995 to 2001. All patients who presented with hiatal hernia surgical problems during this period were included. Endoscopy was performed in all patients with esophageal reflux. Manometry was performed in all patients except those presenting as emergency incarcerations. pH probe testing was performed in those patients in whom it was deemed necessary to establish the diagnosis. Upper gastrointestinal radiographs were used to define anatomy in paraesophageal hernia patients when possible. All patients with esophageal reflux were first treated with a trial of medical therapy. Patients with esophageal reflux and normal esophageal motility underwent 360-degree Nissen fundoplication. Those patients with poor esophageal motility (less than 65 mm of mercury) underwent laparoscopic 270-degree Toupe fundoplication. Patients presenting with paraesophageal herniation underwent laparoscopic repair. When possible esophageal manometry was performed on these patients preoperatively and if normal peristalsis was documented a Nissen fundoplication was performed. If poor esophageal motility was documented before surgery a Toupe fundoplication was performed. Mesh reinforcement of the diaphragmatic hiatus was used if necessary to complete a repair without tension. Patients were followed both by their primary gastroenterologist and their surgeon. Follow-up studies including endoscopy, pH probe, and upper gastrointestinal series were used as necessary in the postoperative period to document any problems as they occurred. Of the 188 patients in the study 141 patients underwent Nissen fundoplication, 21 patients underwent Nissen fundoplication and repair of paraesophageal hernia, 15 underwent Toupe fundoplication, seven underwent Toupe and paraesophageal hernia repair, and four paraesophageal hernia repair alone. One hundred eighty-three patients underwent a laparoscopic operation. Five patients of the 188 underwent an initial open operation-two of these patients because of the size of their paraesophageal hernia. Three of these patients had reoperations of remote operations done years before at other institutions. Twenty-two patients with poor esophageal motility (11.7 %) were included in the study. Fifteen patients required Toupe fundoplication whereas seven patients required Toupe fundoplication and repair of paraesophageal hernias. Mesh repair of paraesophageal hernias was accomplished in ten patients. Patients undergoing Toupe fundoplication had a 13 per cent dysphagia rate less than 4 weeks postoperatively and a 0% dysphagia rate greater than four weeks postoperatively. Patients undergoing Nissen fundoplication had a 16 per cent dysphagia rate less than 4 weeks postoperatively, 2 per cent dysphagia rate greater than 4 weeks postoperatively and no dysphagia at 6 weeks postoperatively. Recurrent symptomatic reflux occurred in 1.4 per cent of Nissen fundoplications and 6.7 per cent of Toupe fundoplications. Of Nissen and paraesophageal repairs 14.2 per cent had reflux and 14.3 per cent of Toupe and paraesophageal repairs had recurrent symptomatic reflux. Overall, complication rate was low. Use of mesh to repair large paraesophageal hernias resulted in a recurrence rate of 0 per cent. There was no instance of infection or bowel fistulization related to the use of mesh. We conclude that laparoscopic Nissen fundoplication in patients with normal esophageal motility is associated with a low rate of dysphagia and a low rate of recurrent reflux. Toupe fundoplication when used in reflux patients with poor esophageal motility is associated with a low rate of dysphagia and an acceptable rate of recurrent reflux. Laparoscop     

Problems associated with a Nissen fundoplication following tracheoesophageal fistula and esophageal atresia repair

Gastroesophageal reflux is frequently associated with esophageal atresia and tracheoesophageal fistula repair. Following unsuccessful medical treatment, 14 (45%) of 31 patients underwent a Nissen fundoplication. Five of these 14 patients had prolonged dysphagia requiring supplemental gastrostomy feeding. Four of these five patients underwent postoperative manometry and extended pH monitoring, which revealed a normal lower-esophageal sphincter pressure (greater than 15 mm Hg), normal pH results, and marked esophageal dysmotility. The fundoplication creates a mechanical obstruction for those patients with a dyskinetic esophagus who cannot generate the pressure to open the "new sphincter". To avoid this complication, antireflux surgery should be deferred, if possible, in those patients with severe gastroesophageal reflux and marked esophageal motility abnormalities.     

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.

Postoperative symptoms and failure after antireflux surgery

BACKGROUND: Outcomes in patients having surgery for gastroesophageal reflux disease are most commonly determined by symptomatic assessment. Objective testing is usually reserved for symptomatic patients. HYPOTHESIS: To evaluate the relationship between symptomatic and objective outcomes after antireflux surgery. DESIGN: Retrospective analysis of prospectively collected data. SETTING: A tertiary care teaching hospital with a comprehensive esophageal physiology laboratory. INTERVENTIONS: A 360 degrees (Nissen) fundoplication or a 270 degrees (Toupet) posterior fundoplication was performed based on esophageal motility. Twenty-four-hour pH monitoring was used as a gold standard for assessing postoperative acid reflux. PATIENTS: Two hundred nine consecutive patients with preoperative and postoperative symptomatic and objective testing performed between January 1, 1996, and June 15, 2001. MAIN OUTCOME MEASURES: Data on preoperative and postoperative symptoms, DeMeester scores, and esophageal motility were prospectively collected. Objective testing was performed after at least 6 months. RESULTS: The preoperative median DeMeester score was 50.0 (interquartile [IQ] range, 30.3-87.0). One hundred eighty patients had a Nissen and 29 patients had a Toupet fundoplication. After a median postoperative interval of 7.7 months (IQ range, 6.7-9.5 months), 174 patients (83.3%) had normal DeMeester scores (median, 2.2; IQ range, 0.8-5.0; P<.001). Of 58 patients (27.7%) who had reflux symptoms after surgery, only 17 (29.3%) had abnormal DeMeester scores (median, 36.9; IQ range, 748.4-20.0; P =.001). Eighteen (11.9%) of the 151 asymptomatic patients had abnormal DeMeester scores (median, 32.5; IQ range, 22.2-57.5; P =.006). CONCLUSIONS: There is poor correlation between postoperative reflux symptoms and actual reflux (abnormal DeMeester scores). Surgeons must be careful to define their terms when reporting success or failure rates after antireflux surgery. Routine use of medical therapy for suppressing postoperative gastroesophageal reflux disease symptoms is not supported by these data, and postoperative therapy should be based on objective testing only.     

Fundoplication improves disordered esophageal motility

Patients with gastroesophageal reflux disease (GERD) and disordered esophageal motility are at risk for postoperative dysphagia, and are often treated with partial (270-degree) fundoplication as a strategy to minimize postoperative swallowing difficulties. Complete (360-degree) fundoplication, however, may provide more effective and durable reflux protection over time. Recently we reported that postfundoplication dysphagia is uncommon, regardless of preoperative manometric status and type of fundoplication. To determine whether esophageal function improves after fundoplication, we measured postoperative motility in patients in whom disordered esophageal motility had been documented before fundoplication. Forty-eight of 262 patients who underwent laparoscopic fundoplication between 1995 and 2000 satisfied preoperative manometric criteria for disordered esophageal motility (distal esophageal peristaltic amplitude ≤30 mm Hg and/or peristaltic frequency ≤80%). Of these, 19 had preoperative manometric assessment at our facility and consented to repeat study. Fifteen (79%) of these patients had a complete fun-doplication and four (21%) had a partial fundoplication. Each patient underwent repeat four-channel esophageal manometry 29.5 ± 18.4 months (mean ± SD) after fundoplication. Distal esophageal peristaltic amplitude and peristaltic frequency were compared to preoperative data by paired t test. After fun-doplication, mean peristaltic amplitude in the distal esophagus increased by 47% (56.8 ± 30.9 mm Hg to 83.5 ± 36.5 mm Hg; P < 0.001) and peristaltic frequency improved by 33% (66.4 ± 28.7% to 87.6 ± 16.3%; P< 0.01). Normal esophageal motor function was present in 14 patients (74%) after fundoplication, whereas in five patients the esophageal motor function remained abnormal (2 improved, 1 worsened, and 2 remained unchanged). Three patients with preoperative peristaltic frequencies of 0%, 10%, and 20% improved to 84%, 88%, and 50%, respectively, after fundoplication. In most GERD patients with esophageal dysmotility, fundoplication improves the amplitude and frequency of esophageal peristalsis, suggesting refluxate has an etiologic role in motor dysfunction. These data, along with prior data showing that postoperative dysphagia is not common, imply that surgeons should apply complete fun-doplication liberally in patients with disordered preoperative esophageal motility.

Multicenter, prospective, double-blind, randomized trial of laparoscopic nissen vs anterior 90 degrees partial fundoplication

HYPOTHESIS: Laparoscopic anterior 90 degrees partial fundoplication for gastroesophageal reflux is associated with a lower incidence of postoperative dysphagia and other adverse effects compared with laparoscopic Nissen fundoplication. DESIGN: A multicenter, prospective, double-blind, randomized controlled trial. SETTING: Nine university teaching hospitals in 6 major cities in Australia and New Zealand. PARTICIPANTS: One hundred twelve patients with proven gastroesophageal reflux disease presenting for laparoscopic fundoplication were randomized to undergo either a Nissen (52 patients) or an anterior 90 degrees partial procedure (60 patients). Patients with esophageal motility disorders, patients requiring a concurrent abdominal procedure, and patients who had undergone previous antireflux surgery were excluded from this study. INTERVENTIONS: Laparoscopic Nissen fundoplication with division of the short gastric vessels or laparoscopic anterior 90 degrees partial fundoplication. MAIN OUTCOME MEASURES: Independent assessment of dysphagia, heartburn, and overall satisfaction 1, 3, and 6 months after surgery using multiple clinical grading systems. Objective measurement of esophageal manometric parameters, esophageal acid exposure, and endoscopic assessment. RESULTS: Postoperative dysphagia, and wind-related adverse effects were less common after a laparoscopic anterior 90 degrees partial fundoplication. Relief of heartburn was better following laparoscopic Nissen fundoplication. Overall satisfaction was better after anterior 90 degrees partial fundoplication. Lower esophageal sphincter pressure, acid exposure, and endoscopy findings were similar for both procedures. CONCLUSIONS: At the 6-month follow-up, laparoscopic anterior 90 degrees culine partial fundoplication is followed by fewer adverse effects than laparoscopic Nissen fundoplication with full fundal mobilization, and it achieves a higher rate of satisfaction with the overall outcome. However, this is offset to some extent by a greater likelihood of recurrent gastroesophageal reflux symptoms.     

Indications for the laparoscopic treatment of gastroesophageal reflux disease.

BACKGROUND: The aim of the study was to evaluate the indications and surgical techniques for the treatment of gastroesophageal reflux disease. METHODS: From 1998 through 2000, we performed gastroesophageal reflux surgery on 12 patients. Preoperative studies revealed third-degree esophagitis in most patients with no functional alterations of the esophagus itself. The patients underwent a laparoscopic Nissen-Rossetti fundoplication. No conversions to open laparotomy were necessary. The mean operative time was 180 minutes. RESULTS: No intraoperative or immediate postoperative complications occurred. The mean postoperative stay was 6.2 days. Transitory postoperative dysphagia was noted in 8 patients. In 5 patients, it was mild and regressed after 2 weeks; in 3 cases, it was severe and regressed over 2 months. CONCLUSION: A laparoscopic surgical approach is a satisfactory method for correcting gastroesophageal reflux disease. The efficacy of medical therapy has been well established. However, in the young person who may be required to take medication for many years or in those persons who are intolerant of standard medical therapy for gastroesophageal reflux disease, a surgical intervention is a satisfactory option. The success of medical therapy can be used as a predictive criterion of the success of laparoscopic Nissen-Rosetti fundoplication when normal motility of the esophageal corpus is present.     

The effect of medical therapy and antireflux surgery on dysphagia in patients with gastroesophageal reflux disease without esophageal stricture

BACKGROUND: Poor esophageal body motility and trapping of the hernial sac by the hiatal crura are the major pathomechanisms of gastroesophageal reflux disease (GERD)-induced dysphagia. There is only little knowledge of the effect of medical therapy or antireflux surgery in reflux-induced dysphagia. METHODS: Fifty-nine consecutive GERD patients with dysphagia were studied by means of a symptom questionnaire, endoscopy, barium swallow, esophageal manometry, and 24-hour pH monitoring of the esophagus. Patients had proton pump inhibitor therapy and cisapride for 6 months. After GERD relapsed following withdrawal of medical therapy, 41 patients decided to have antireflux surgery performed. The laparoscopic Nissen fundoplication was chosen in 12 patients with normal esophageal body motility and the laparoscopic Toupet fundoplication in 29 patients with impaired peristalsis. Dysphagia was assessed prior to treatment, at 6 months of medical therapy, and at 6 months after surgery. RESULTS: Heartburn and esophagitis were effectively treated by medical and surgical therapy. Only surgery improved regurgitation. Dysphagia improved in all patients following surgery but only in 16 patients (27.1%) following medical therapy. Esophageal peristalsis was strengthened following antireflux surgery. CONCLUSIONS: Medical therapy fails to control gastroesophageal reflux as it does not inhibit regurgitation. Thus, it has little effect on reflux-induced dysphagia. Surgery controls reflux and improves esophageal peristalsis. This may contribute to its superiority over medical therapy in the treatment of GERD-induced dysphagia.     

Prospective double-blind randomized trial of laparoscopic Nissen fundoplication with division and without division of short gastric vessels.

OBJECTIVE: To determine whether division of the short gastric vessels (SGVs) and full mobilization of the gastric fundus is necessary to reduce the incidence of postoperative dysphagia and other adverse sequelae of laparoscopic Nissen fundoplication. SUMMARY BACKGROUND DATA: Based on historical and uncontrolled studies, division of the SGVs has been advocated during laparoscopic Nissen fundoplication to improve postoperative clinical outcomes. However, this modification has not been evaluated in a large prospective randomized trial. METHODS: One hundred two patients with proven gastroesophageal reflux disease presenting for laparoscopic Nissen fundoplication were prospectively randomized to undergo fundoplication with (52 patients) or without (50 patients) division of the SGVs. Patients with esophageal motility disorders, patients requiring a concurrent abdominal procedure, and patients who had undergone previous antireflux surgery were excluded. Patients were blinded to the postoperative status of their SGVs. Clinical assessment was performed by a blinded independent investigator who used multiple standardized clinical grading systems to assess dysphagia, heartburn, and patient satisfaction 1, 3, and 6 months after surgery. Objective measurement of lower esophageal sphincter pressure, esophageal emptying time, and distal esophageal acid exposure and radiologic assessment of postoperative anatomy were also performed. RESULTS: Operating time was increased by 40 minutes (median 65 vs. 105) by vessel division. Perioperative outcomes and complications, postoperative dysphagia, relief of heartburn, and overall satisfaction were not improved by dividing the SGVs. Lower esophageal sphincter pressure, acid exposure, and esophageal emptying times were similar for the two groups. CONCLUSION: Division of the SGVs during laparoscopic Nissen fundoplication did not improve any clinical or objective postoperative outcome.     

Radiologic evaluation of the esophagus: methods and value in motility disorders and GERD

The barium esophagram is an essential component in the workup of a patient with dysphagia and gastroesophageal reflux disease, especially when considering antireflux surgery or after such surgery. The examination requires a flexible approach with an emphasis on the motility portion of the examination. When properly performed, the examination should identify the following: normal or impaired esophageal emptying; normal or abnormal motility; the presence and type of hiatal hernia; the presence of a distal stricture or mucosal ring; and in many instances, the presence of gastroesophageal reflux. In patients after antireflux surgery, the examination should identify the following: normal of impaired esophageal emptying; normal or abnormal motility; the location, tightness, and length of the fundoplication; the presence of a recurrent hernia; and the presence of gastroesophageal reflux.     

Minimally invasive surgery for gastroesophageal reflux disease

: The goal of this study was to determine if the outcome of antireflux surgery can be improved by: (1) conducting a careful preoperative workup to characterize gastroesophageal reflux disease (GERD) in the individual patient; and (2) tailoring the operation to the results of the preoperative function tests. : Sixty-eight patients had operations for GERD by minimally invasive techniques. : A Rossetti fundoplication was performed in 22 patients. Sixty-eight percent became asymptomatic. Twenty-seven percent developed dysphagia or gas bloat. Thirty-five patients had a Nissen fundoplication. Ninety-one percent are asymptomatic. Eleven patients with severe abnormalities of esophageal peristalsis underwent a Guarner fundoplication with relief of symptoms in 82% of patients. No patients in the Nissen or Guarner group developed postoperative persistent dysphagia or gas bloat. A pyloromyotomy was performed in 3 patients because of severe delayed gastric emptying. : Minimally invasive surgery for GERD gives good-to-excellent results even in patients with abnormal esophageal body function, provided that the operation is tailored to the individual patient based on the results of the preoperative function tests.
