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.     

A prospective randomized trial of laparoscopic Nissen fundoplication with anterior vs posterior hiatal repair.

HYPOTHESIS: The technique used for repair of the esophageal hiatus during laparoscopic Nissen fundoplication can influence the likelihood of postoperative dysphagia. DESIGN: A prospective double-blind randomized control trial. SETTING: A university teaching hospital. PARTICIPANTS: A total of 102 patients with proven gastroesophageal reflux disease, undergoing a laparoscopic Nissen fundoplication were randomized to undergo fundoplication with either anterior (47 patients) or posterior (55 patients) repair of the diaphragmatic hiatus. Patients were excluded for the following reasons: they had esophageal motility disorders, required a concurrent abdominal procedure, had undergone previous antireflux surgery, or had very large hiatus hernias. INTERVENTIONS: Laparoscopic Nissen fundoplication with anterior vs posterior hiatal repair. MAIN OUTCOME MEASURES: Independent assessment of dysphagia, heartburn, patient satisfaction, and other symptoms 1, 3, and 6 months following surgery, using multiple standardized clinical grading systems. Objective measurement of lower esophageal sphincter pressure, esophageal emptying time, distal esophageal acid exposure, and endoscopic assessment of postoperative anatomy and esophageal mucosa. RESULTS: Symptoms of postoperative dysphagia, relief of heartburn, and overall satisfaction 6 months after surgery were not influenced by the hiatal repair technique. However, to achieve a similar incidence of dysphagia, more patients who initially underwent posterior hiatal repair required a second surgical procedure (6 vs 0 patients). The hiatal repair technique did not affect the likelihood of early postoperative paraesophageal herniation. CONCLUSION: Anterior suturing of the hiatus appears to be at least as good in the short-term as posterior suturing as a method of narrowing the hiatus during laparoscopic Nissen fundoplication.     

Chronic dysphagia following laparoscopic fundoplication

BACKGROUND: Many surgeons practise tailored laparoscopic antireflux surgery in an attempt to prevent postoperative dysphagia. The aim of this study was to determine the effect of 360 degrees fundoplication (Nissen) or 270 degrees fundoplication (Toupet), and the influence of abnormal oesophageal peristalsis, upon postoperative dysphagia. METHODS: This was a cohort study from three tertiary referral centres, using dysphagia before laparoscopic fundoplication and 1 year after operation as the main outcome variable. Preoperative oesophageal manometry was performed on all patients. RESULTS: Some 761 patients underwent Nissen and 85 underwent Toupet fundoplication. Only 2 per cent reported severe postoperative dysphagia. There was a significant selection bias towards the Toupet operation for patients with abnormal oesophageal motility (P < 0.001). For patients whose oesophageal manometric findings were normal there was a significant improvement in dysphagia after Nissen fundoplication (P = 0.02), and no significant change following Toupet fundoplication. There was no significant change in the rate of dysphagia following either method of fundoplication amongst other subgroups in which oesophageal manometry was stratified as non-specific motor disorder, low-amplitude peristalsis, or aperistalsis. CONCLUSION: A tailored approach to the degree of fundoplication is unnecessary as patients with dysmotility suffer no more dysphagia after full laparoscopic Nissen fundoplication than those who have a partial Toupet wrap.     

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 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.

Dysphagia after laparoscopic antireflux surgery. The impact of operative technique.

BACKGROUND. Concerns about laparoscopic antireflux surgery include the frequent appearance of troublesome postoperative dysphagia. This study reviews the frequency of early (less than 6 weeks) and persistent (greater than 6 weeks) solid food dysphagia in patients undergoing Toupet, Rosetti-Nissen, or Nissen fundoplications. METHODS. One hundred eighty-four consecutive patients with normal esophageal peristalsis undergoing laparoscopic antireflux surgery were prospectively studied. Before operation, all patients had endoscopy, 24-hour pH study, and an esophageal motility study. The choice of operation was dependent on anatomy and surgeon preference. Before discharge, all patients were given instructions on a soft diet. Postoperative symptoms were scored by the patients as absent, mild, moderate, or severe 4 weeks and 12 weeks after operation. The option of esophageal dilation was offered to patients with moderate to severe persistent solid food dysphagia. RESULTS. New onset moderate to severe dysphagia to solid foods was present in 30 (54%), 8 (17%), and 13 (16%) patients undergoing Rosetti-Nissen, Nissen, and Toupet fundoplications, respectively, in the first month after operation (p < 0.001). Moderate to severe dysphagia persisted at 3 months in six (11%), one (2%), and two (2%) patients undergoing laparoscopic Rosetti-Hell, Nissen, and Toupet fundoplications, respectively (p < 0.05). Esophageal dilatation was performed in five (4%), zero, and one (1%) patients undergoing laparoscopic Rosetti-Nissen, Nissen, and Toupet fundoplications, respectively (p < 0.05). There was no additional morbidity related to division of short gastric vessels in patients undergoing Nissen fundoplication. CONCLUSIONS. Laparoscopic Rosetti-Nissen fundoplication is associated with a higher rate of early and persistent postoperative dysphagia than either laparoscopic Nissen fundoplication or Toupet fundoplication. Consideration of complete fundus mobilization should be a part of all laparoscopic antireflux procedures.     

Laparoscopic anterior esophageal myotomy and toupet fundoplication for achalasia.

Achalasia is an esophageal motility disorder characterized by the failure of lower esophageal sphincter relaxation and the absence of esophageal peristalsis. The purpose of this study was to evaluate the clinical outcomes of patients undergoing laparoscopic esophageal myotomy and Toupet fundoplication for achalasia. A 9-cm myotomy was performed in most cases extending 7 cm above and 2 cm below the gastroesophageal junction. Severity of dysphagia, heartburn, chest pain, and regurgitation was graded preoperatively and postoperatively using a five-point symptomatic scale (0-4). Patients also graded their outcomes as excellent, good, fair, or poor. Between December 1995 and November 2000 a total of 49 patients (23 male, 26 female) with a mean age of 44.3 years (range 23-71 years) were diagnosed with achalasia. Mean duration of symptoms was 40.2 months (range 4-240 months). Thirty-seven patients (76%) had had a previous nonsurgical intervention or combinations of nonsurgical interventions [pneumatic dilation (23), bougie dilation (five), and botulinum toxin (19)], and two patients had failed esophageal myotomies. Forty-five patients underwent laparoscopic esophageal myotomy and Toupet fundoplication. Two patients received laparoscopic esophageal myotomies without an antireflux procedure, and two were converted to open surgery. One patient presented 10 hours after a pneumatically induced perforation and underwent a successful laparoscopic esophageal myotomy and partial fundoplication. Mean operative time was 180.5 minutes (range 145-264 minutes). Mean length of stay was 1.98 days (range 1-18 days). There were five (10%) perioperative complications but no esophageal leaks. There was a significant difference (P < 0.05) between the preoperative and postoperative dysphagia, chest pain, and regurgitation symptom scores. All patients stated that they were improved postoperatively. Eighty-six per cent rated their outcome as excellent, 10 per cent as good, and 4 per cent as fair. Laparoscopic anterior esophageal myotomy and Toupet fundoplication effectively alleviates dysphagia, regurgitation, and chest pain accompanying achalasia and is associated with high patient satisfaction, a rapid hospital discharge, and few complications.     

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.

Laparoscopic Heller myotomy with Toupet fundoplication: outcomes predictors in 121 consecutive patients

HYPOTHESIS: This study was performed to assess the intermediate-term outcomes after laparoscopic Heller myotomy and posterior Toupet fundoplication in a single-surgeon series with the expectation of identifying patient and disease factors associated with poor outcomes. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Tertiary care teaching hospital with a comprehensive esophageal physiology laboratory. PATIENTS: A total of 121 patients undergoing laparoscopic Heller myotomy with Toupet fundoplication (between December 1, 1996, and December 31, 2004) for achalasia were included. INTERVENTIONS: All patients had preoperative objective documentation of achalasia. A 5- to 6-cm-long myotomy was performed on the distal esophagus. The myotomy incision was extended 2 cm onto the stomach. A partial (270 degrees ) posterior Toupet fundoplication was performed as an antireflux mechanism in all patients. MAIN OUTCOME MEASURES: Data on preoperative and postoperative symptoms, manometry, and 24-hour ambulatory pH were prospectively collected. Symptoms were recorded with a standardized assessment tool. Patients with postoperative dysphagia scores of 2 or greater were considered treatment failure. Logistic regression modeling was performed to identify variables significant for poor outcomes. RESULTS: Preoperatively, 89 patients (73.6%) had severe dysphagia (dysphagia score, 3 or 4) and 32 patients (26.4%) had mild or moderate dysphagia (dysphagia score, 1 or 2). After a median follow-up period of 9 months, 102 patients (84.3%) (P<.001) had excellent relief of dysphagia (dysphagia score, 0 or 1). Eight additional patients (6.6%) demonstrated a significant (25%-75% [P=.01]) improvement in dysphagia scores. Only 11 patients (9.0%) had either no change or worse dysphagia. Postoperatively, all patients with manometry had a normal lower esophageal sphincter pressure (mean +/- SD, 14.7 +/- 6.6 mm Hg; P<.001) and good lower esophageal sphincter relaxation. Odds of failure were greatest for patients with severe preoperative dysphagia, male patients, and patients with classic amotile achalasia. Of the 60 patients having heartburnlike symptoms preoperatively (mean +/- SD score, 2.52 +/- 1.00), 19 (31.7%) continued to have similar symptoms after surgery. Sixteen (33.3%) of the 48 patients having postoperative pH studies demonstrated objective reflux (DeMeester score, >14.7). Five (31.2%) of these patients had symptoms of their reflux. CONCLUSIONS: Dysphagia improves in most patients after laparoscopic Heller myotomy with partial fundoplication. Patients with severe preoperative dysphagia, esophageal dilation, or amotile achalasia may have greater chances of a poor outcome.     

Laparoscopic Heller myotomy with Toupet fundoplication for achalasia straightens the esophagus and relieves dysphagia

BACKGROUND: A standard procedure for the treatment of achalasia remains to be established. We assessed the usefulness of a laparoscopic Heller myotomy with a Toupet fundoplication (LHT). METHODS: LHT was performed in 30 patients (12 men, 18 women; mean age, 41.8 y) who had esophageal achalasia with severe dysphagia. Caution was exercised when the esophagus was pulled downward and straightened. Symptoms and esophageal function were evaluated before and after surgery. RESULTS: The esophagus was straightened surgically in 22 (88%) of 25 patients with esophageal curvature on preoperative esophagography. The dysphagia score decreased to 1.7 +/- 1.2 (mean +/- SD) points from a preoperative value of 10. The lower esophageal sphincter pressure decreased significantly. Two patients (7%) had esophageal diverticula as postoperative sequelae. Pathologic acid reflex was noted in 3 patients (12%). CONCLUSIONS: LHT is a useful procedure for straightening the esophagus, reducing lower esophageal sphincter pressure, and relieving dysphagia in patients with achalasia.     

Early reoperation following laparoscopic antireflux surgery

PURPOSE: To assess the outcome for patients undergoing early reoperation following laparoscopic antireflux surgery. METHODS: The outcome was prospectively determined for 28 patients who underwent 30 reoperative procedures within 4 weeks of their initial laparoscopic fundoplication between 1992 and 1998. Follow-up ranged from 3 months to 4 years (median 2 years). Before mid 1994, patients were assessed and managed based on clinical findings (first 192 patients in overall series), whereas subsequently (for the most recent 530 patients) all patients underwent routine early postoperative barium swallow radiography, and laparoscopic exploration during the first postoperative week if problems were suspected. RESULTS: The reoperations were performed for acute paraoesophageal hiatus hernia (8 patients), tight oesophageal hiatus (7), postoperative haemorrhage (3), tight Nissen fundoplication (8), early recurrent reflux (1), and coeliac/superior mesenteric artery thrombosis (1). Two patients required a second operation for persistent dysphagia due to a tight hiatus. Both patients initially underwent loosening of their fundoplication. Before mid 1994, reoperations were usually undertaken by an open approach, whereas subsequently a laparoscopic approach has usually been successful. Laparoscopic reintervention was easily achieved within 7 days of the first procedure whereas subsequent surgery was more difficult and often required open surgery. The change in protocol was associated with an improvement in overall patient satisfaction and dysphagia in the latter part of this experience. CONCLUSIONS: Routine early contrast radiology following laparoscopic fundoplication and a low threshold for laparoscopic reexploration facilitates early identification of postoperative problems at a time when laparoscopic correction is easily achieved. This may result in an improved overall outcome for patients requiring early reintervention following laparoscopic antireflux surgery.     

Laparoscopic refundoplication with prosthetic hiatal closure for recurrent hiatal hernia after primary failed antireflux surgery

BACKGROUND: One of the most frequent complications after laparoscopic antireflux surgery is estimated to be the intrathoracic herniation of the wrap into the chest. Therefore, in up to 5% of patients, revisional surgery is necessary. HYPOTHESIS: Patients who undergo laparoscopic refundoplication for postoperative intrathoracic wrap herniation using a circular polypropylene mesh for hiatal closure have a good to excellent functional outcome, during a complete follow-up of 1 year. DESIGN: Prospective nonrandomized trial of a consecutive sample. SETTING: University-affiliated community hospital. PATIENTS: Twenty-four patients undergoing laparoscopic refundoplication for persistent or recurrent symptoms of gastroesophageal reflux disease as a result of postoperative intrathoracic wrap migration. INTERVENTION: All patients underwent laparoscopic refundoplication with a circular polypropylene mesh for hiatal closure. MAIN OUTCOME MEASURES: Recurrences, complications, postoperative lower esophageal sphincter pressure, DeMeester score, esophagogastroduodenoscopy results, and barium swallow results. RESULTS: All refundoplications were completed laparoscopically. There were no intraoperative complications. Twenty-one patients underwent laparoscopic Nissen fundoplication; in 3 patients, a laparoscopic Toupet fundoplication was performed. Previous antireflux procedures included an open Nissen fundoplication (n = 5), a laparoscopic Nissen fundoplication (n = 15), and a laparoscopic Toupet fundoplication (n = 4). Postoperatively, one patient had severe dysphagia and had to undergo pneumatic dilatation once. During a follow-up of 1 year after surgery, no patient developed a recurrent hiatal hernia, with or without intrathoracic wrap herniation. The mean lower esophageal sphincter pressure increased significantly (P<.01) at 3 months (12.2 mm Hg) and 1 year (11.9 mm Hg) after refundoplication. The mean DeMeester score decreased significantly (P<.01) from 50.5 points preoperatively to 16.0 points at 3 months and 14.7 points at 1 year after refundoplication. CONCLUSION: Laparoscopic refundoplication with prosthetic hiatal closure is a safe and effective procedure for preventing recurrent intrathoracic wrap herniation, with good to excellent functional outcome for a complete follow-up of 1 year.

Laparoskopische Fundoplicatio nach Nissen und Toupet bei Patienten mit gastroösophagealer Refluxkrankheit und Motilitätsstörung des distalen Ösophagus

INTRODUCTION: A Nissen fundoplication for gastrooesophageal reflux disease may more often lead to persistent dysphagia than a Toupet fundoplication. The aim of this study was to assess the results of laparoscopic Nissen versus Toupet fundoplication in patients with reflux disease and impaired distal esophageal motility. PATIENTS AND METHODS: In 15 patients a laparoscopic Nissen and in 17 a laparoscopic Toupet fundoplication was carried out. Criteria for an impaired motility of the distal esophagus were a mean amplitude of < 30 mm Hg of swallow-induced contractions, or > 33% non-propulsive or non-transmitted contraction waves. Before surgery, heartburn, dysphagia, regurgitation and other symptoms were scored and endoscopic, manometric and 24 hour pH-metric investigations performed. Patients were reinvestigated 3 to 30 (median 15) months after Nissen and 3 to 42 (median 7) months after Toupet fundoplication. RESULTS: After Nissen as well as after Toupet fundoplication heartburn was significantly less frequent, whereas dysphagia and all other symptom-scores remained unchanged. In the 26 patients reinvestigated manometrically, the resting pressure of the lower esophageal sphincter was significantly higher following both operations and the residual sphincter pressure upon swallowing higher only after Nissen fundoplication. The amplitude of swallow-induced contractions and the percentages of non-propulsive and non-transmitted contraction waves were not significantly changed after either operation. In the 23 patients restudied pH-metrically, reflux activity was significantly reduced after both Nissen and Toupet fundoplication. CONCLUSION: In patients with reflux disease and impaired distal esophageal motility, laparoscopic Nissen and Toupet fundoplication both yielded satisfactory results and neither operation led to increased dysphagia.     

Laparoscopic cardiomyotomy for achalasia after failed balloon dilatation

Background: This study was designed to determine the feasibility and outcome of laparoscopic cardiomyotomy in patients with achalasia who have persistent or recurrent dysphagia following balloon dilatation. Methods: Ten patients who had undergone a minimum of two (range, two to seven) previous balloon dilatations underwent a single anterior cardiomyotomy extending from the gastroesophageal junction onto the esophagus proximally for 6 cm. Four patients had a Toupet fundoplication. Patients were analyzed using pre- and postoperative DeMeester symptom scores for dysphagia, regurgitation, and heartburn (0 = none–3 = maximal) and esophageal manometry. Results: Mean operating time was 90 min. Periesophagitis was noted in some patients but was rarely troublesome. Submucosal fibrosis was present in all patients and made dissection more difficult particularly around the cardioesophageal junction. As a result, three patients had mucosal perforations that required repair by laparoscopic suturing. There were no subsequent postoperative complications. Median (IQR) postoperative stay was 3 (2–4) days. At 3-month reassessment, there was a reduction in the median dysphagia score from 3 to 0, and also in the regurgitation score from 3 to 0. At last follow-up (median, 22 months), one patient had developed recurrent dysphagia (grade 2), which improved with dilatation. Overall success of the laparoscopic procedure was therefore 90%. Only one patient developed new symptoms of reflux (mild, grade 1) after surgery. Conclusions: Laparoscopic cardiomyotomy provides good control of the symptoms of dysphagia and regurgitation without the morbidity of a laparotomy or thoracotomy incision. Although technically more difficult, the technique can be extended to those who have had previous balloon dilatation with complication and success rates similar to published results in patients who have not undergone previous dilatation.

Selective application of fundoplication during laparoscopic heller myotomy ensures favorable outcomes

We propose that selective fundoplication during laparoscopic Heller myotomy achieves optimal outcomes. Fundoplication was applied selectively in 21 of 100 patients undergoing laparoscopic Heller myotomy with hiatus hernia, patulous esophageal hiatus, or intraoperative perforation. Dysphagia and heartburn incidence and severity in patients undergoing myotomy with or without fundoplication were compared before and after myotomy. Median follow-up was 19 months and was similar for both groups. Preoperative symptoms were similar for both groups of patients and showed significant improvement following myotomy with or without fundoplication. As well, there were no significant differences in postoperative dysphagia (26% vs. 14%), dysphagia score (1.1 +/- 1.4 vs. 0.8 +/- 1.3), heartburn (21% vs. 27%), or heartburn score (0.9 +/- 1.5 vs. 1.4 +/- 1.6). Overall improvement was seen in 86% of patients undergoing myotomy with fundoplication and in 97% without fundoplication (P = 0.06). Selective application of fundoplication during laparoscopic Heller myotomy promotes optimal outcomes.     

Preoperative esophageal transit studies are a useful predictor of dysphagia after fundoplication

Fundoplication performed for gastroesophageal reflux disease may be complicated by postoperative dysphagia despite successful reduction in reflux symptoms. This is more likely in those patients with reflux who have concurrent esophageal dysmotility. The aim of this study was to establish whether esophageal transit studies using a technetium-99m jello bolus (jello esophageal transit) could detect the presence of motility disorders preoperatively and hence predict surgical outcome. Transit studies in 33 healthy volunteers yielded a normal range of 2 to 24 seconds using ninety-fifth percentile distribution. In the second phase of the study, 26 patients accepted for laparoscopic fundoplication were enrolled: jello esophageal transit, manometry, and endoscopy were attempted preoperatively in all subjects. A clinical dysphagia score was assigned from a questionnaire. Six months after surgery, five patients had dysphagia and of these four were found to have abnormal preoperative jello esophageal transit, for a sensitivity of 80%. Of the 21 patients who had no dysphagia after surgery, 20 patients had normal preoperative jello esophageal transit, showing a specificity of 95%. This esophageal transit study is noninvasive, reliable, and sensitive. When performed prior to fundoplication, it appears to be of significant value in detecting a subtle functional motility disorder that predisposes to postoperative dysphagia. Jello esophageal transit may assist the surgeon in planning treatment of gastroesophageal reflux disease.

Laparoscopic repair of gastroesophageal reflux disease

Summary This report describes our preliminary experience with two surgical laparoscopic fundoplication procedures, the Nissen technique and the Toupet operation, in which the fundal wrap is reduced from 360° to 180–200°. Fourteen patients with symptomatic gastroesophageal reflux disease who were refractory to pharmacologic and medical therapy underwent a laparoscopic Nissen fundoplication; in an additional 14 patients, we performed a laparoscopic Toupet partial fundoplication. Our laparoscopic approach to the two procedures does not differ significantly from the traditional open methods and the effectiveness of the laparoscopic fundoplication procedures appears similar to that of the same conventional techniques. Oral feedings can be resumed on the first postoperative day and patients typically are discharged on the second day after surgery. Operative time for performing the Toupet procedure averaged just approximately 1.6 h and was shorter than that for the Nissen fundoplication, due to the use of a stapler to secure the fundal wrap. Confirming earlier observations, the laparoscopic Toupet 180–200° fundoplication was associated with a lower incidence of postoperative digestive complications, such as dysphagia, than was the laparoscopic Nissen operation. The laparoscopic fundoplication approach offers the advantages of clear visualization, adequate dissection and precise repair, along with the benefits associated with endoscopic surgery: diminished postoperative pain and discomfort, reduced hospitalization, and quicker return to normal activities. Our experience indicates that the Toupet fundoplication may be preferable to the Nissen technique for many patients requiring surgical treatment of their reflux disease.     

Randomized clinical trial of laparoscopic versus open fundoplication for gastro-oesophageal reflux disease

BACKGROUND: The aim of this study was to compare laparoscopic and open Nissen fundoplication for gastro-oesophageal reflux disease in a randomized clinical trial. METHODS: Ninety-nine patients were randomized to either laparoscopic (52) or open (47) Nissen fundoplication. Patients with oesophageal dysmotility, those requiring a concurrent abdominal procedure and those who had undergone previous antireflux surgery were excluded. Independent assessment of dysphagia, heartburn and patients' satisfaction 1, 3, 6 and 12 months after surgery was performed using multiple standardized clinical grading systems. Objective measurement of oesophageal acid exposure and lower oesophageal sphincter pressure before and after surgery, and endoscopic assessment of postoperative anatomy, were performed. RESULTS: Operating time was longer in the laparoscopic group (median 82 versus 46 min). Postoperative pain, analgesic requirement, time to solid food intake, hospital stay and recovery time were reduced in the laparoscopic group. Perioperative outcomes, postoperative dysphagia, relief of heartburn and overall satisfaction were equally good at all follow-up intervals. Reduction in oesophageal acid exposure, increase in lower oesophageal sphincter tone and improvement in endoscopic appearances were the same for the two groups. CONCLUSION: The laparoscopic approach to Nissen fundoplication improved early postoperative recovery, with an equally good outcome up to 12 months.
