Laparoscopic Heller myotomy and Dor fundoplication for achalasia: analysis of successes and failures.

BACKGROUND: In the treatment of achalasia, surgery has been traditionally reserved for patients with residual dysphagia after pneumatic dilatation. The results of laparoscopic Heller myotomy have proven to be so good, however, that most experts now consider surgery the primary treatment. HYPOTHESIS: The outcome of laparoscopic myotomy and fundoplication for achalasia is dictated by technical factors. SETTING: University hospital tertiary care center. DESIGN: Retrospective study. PATIENTS AND METHODS: One hundred two patients with esophageal achalasia underwent laparoscopic Heller myotomy and Dor fundoplication. Fifty-seven patients had been previously treated by pneumatic dilatation or botulinum toxin. The design of the operation involved a 7-cm myotomy, which extended 1.5 cm onto the gastric wall, and a Dor fundoplication. Esophagrams, esophageal manometric findings, and video records of the procedure were analyzed to determine the technical factors that contributed to the clinical success or failure of the operation. MAIN OUTCOME MEASURE: Swallowing status. RESULTS: In 91 (89%) of the 102 patients, good or excellent results were obtained after the first operation. A second operation was performed in 5 patients to either lengthen the myotomy (3 patients) or take down the fundoplication (2 patients). Dysphagia resolved in 4 of these patients. The remaining 6 patients were treated by pneumatic dilatation, but dysphagia improved in only 1. At the conclusion of treatment, excellent or good results had been obtained in 96 (94%) of the 102 patients. CONCLUSIONS: These data show that a Heller myotomy was unsuccessful in patients with an esophageal stricture; a short myotomy and a constricting Dor fundoplication were the avoidable causes of residual dysphagia; a second operation, but not pneumatic dilatation, was able to correct most failures; and that the identified technical flaws were eliminated from the last half of the patients in the series.     

Laparoscopic Heller myotomy and Dor fundoplication for esophageal achalasia in children

BACKGROUND/PURPOSE: In the past, surgical treatment in achalasia usually has been reserved for patients whose dysphagia does not respond to pneumatic dilatation. The success of minimally invasive myotomy, however, has resulted in a shift in practice in adult patients, whereby laparoscopic surgery is becoming preferred as primary treatment by most gastroenterologists and surgeons. The aim of this study was to assess the efficacy of laparoscopic Heller myotomy and Dor fundoplication for esophageal achalasia in children. METHODS: Thirteen patients with esophageal achalasia (median age, 15 years; 6 boys and 7 girls; median duration of symptoms, 24 months) underwent laparoscopic Heller myotomy and Dor fundoplication between 1996 and 1999. Two patients had been treated previously by pneumatic dilatation, and 1 patient had received intrasphincteric Botulinum toxin injections. RESULTS: Median duration of the operation was 130 minutes. The patients were fed after an average of 33 hours, and they all left the hospital within 2 days. At a median follow-up of 19 months, there was no residual dysphagia in any patient. CONCLUSIONS: Laparoscopic Heller myotomy and Dor fundoplication were effective and safe for children with esophageal achalasia. Hospital stay and recovery time was short, and the functional results were excellent. These data support the notion that laparoscopic Heller myotomy should become the primary treatment of esophageal achalasia in children.     

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 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.     

Comparison of laparoscopic total and partial fundoplication for gastroesophageal reflux

Approximately 25% of patients with gastroesophageal reflux, severe enough to be considered for surgical treatment have dysfunction of esophageal peristalsis in addition to dysfunction of the lower esophageal sphincter. A standard total (i.e., Nissen) fundoplication in these patients may be followed by dysphagia, so many experts recommend a partial fundoplication as an alternative. The goal of this study was to compare the clinical results and changes in esophageal function following laparoscopic total and partial fundoplication. Ninety-three patients with gastroesophageal reflux disease had laparoscopic antireflux operations. Total fundoplication was performed in 50 patients with normal esophageal peristalsis. Partial fundoplication was chosen for 43 patients with severe abnormalities of esophageal peristalsis. Partial fundoplication of patients has resolution of heartburn (93%) and regurgitation (97%) after partial as compared to total fundoplication. Dysphagia developed in four patients (8%) after total fundoplication (one patient required dilatation) and in no patients after partial fundoplication. Both operations produced similar changes in lower esophageal sphincter function, but only partial fundoplication was associated with improvement in esophageal dysfunction. Esophageal acid exposure became normal in 92% of patients after total and in 91% of patients after partial fundoplication. Partial fundoplication improves lower esophageal sphincter pressure and esophageal body function and, in patients with abnormal esophageal peristalsis, it corrects reflux without producing dysphagia. Partial and total fundoplication are both indicated in patients with gastroesophageal reflux disease, and the choice of which procedure to use should be based on each patient's specific esophageal motor function abnormalities.

Impact of laparoscopic nissen fundoplication with prosthetic hiatal closure on esophageal body motility: Results of a prospective randomized trial

HYPOTHESIS: Prosthetic crural closure does not adversely influence esophageal body motility. In most patients, postoperative increased dysphagia resolves spontaneously during the first months after surgery. DESIGN: Prospective randomized trial. We compared patients who underwent laparoscopic Nissen fundoplication with simple sutured hiatal closure and those who underwent laparoscopic Nissen fundoplication with prosthetic hiatal closure. SETTING: University-affiliated community hospital. PATIENTS: Forty consecutive patients who underwent laparoscopic Nissen fundoplication for gastroesophageal reflux disease. INTERVENTIONS: A 360 degrees Nissen fundoplication with simple sutured crura (n = 20; nonmesh group) vs the same procedure with posterior 1 x 3-cm polypropylene onlay mesh prosthesis (n = 20; mesh group). MAIN OUTCOME MEASURES: Recurrences; postoperative dysphagia rate; localization, length, and pressure of the lower esophageal sphincter (LES); results of 24-hour pH monitoring; esophageal body motility; peristalsis; and esophageal amplitude of contraction and interrupted waves. RESULTS: Preoperatively, both groups had pathological LES pressure and DeMeester scores. These values improved significantly (P < .01) after surgery and remained stable at 1 year after surgery. Patients in the nonmesh group had a significantly lower LES pressure 1 year after surgery compared with those in the mesh group. There were no significant differences in postoperative mean LES length (4.1 vs 3.8 cm), LES relaxation (93.4% vs 92.4%), and intra-abdominal LES length (2.1 vs 2.1 cm). Patients in the mesh group had fewer simultaneous waves and interrupted waves 1 year after surgery, but the difference between groups was not significant. There were no significant differences in interrupted waves and amplitude of contraction between groups 1 year after surgery. CONCLUSION: Laparoscopic Nissen fundoplication with prosthetic crural closure does not impair postoperative esophageal body motility compared with laparoscopic Nissen fundoplication with simple suture hiatal closure, although it is associated with a higher rate of short-term dysphagia.     

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 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     

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 Heller myotomy relieves dysphagia in achalasia when the esophagus is dilated

Background: It has been said that a Heller myotomy cannot improve dysphagia in achalasia when the esophagus is markedly dilated or sigmoid shaped. Those who hold this belief recommend esophagectomy as the primary treatment in such cases. This study aimed to compare the results of laparoscopic Heller myotomy combined with Dor fundoplication in 66 patients with and without esophageal dilatation, all of whom had achalasia. Methods: On the basis of the maximal diameter of the esophageal lumen and the shape of the esophagus, the patients were placed into four groups: group A (esophageal diameter <4.0 cm; 26 patients), group B (diameter 4.0–6.0 cm; 21 patients), group C1 (diameter >6.0 cm and straight esophageal axis; 12 patients), and group C2 (diameter >6.0 cm and sigmoid-shaped esophagus; 7 patients). All patients underwent a laparoscopic Heller myotomy and Dor fundoplication. Results: The duration of the operation and the length of hospital stay were similar among the four groups. Excellent or good results were obtained in 88% of group A, 100% of group B, 83% of group C1, and 100% of group C2. No patient in this consecutive series ultimately required an esophagectomy. Conclusions: In patients with achalasia who have esophageal dilation, a laparoscopic Heller myotomy and Dor fundoplication (a) took no longer and was no more difficult, (b) was associated with no more postoperative complications, and (c) gave just as good relief of dysphagia. We conclude that esophageal dilation by itself should rarely serve as an indication for esophagectomy rather than myotomy as the initial surgical treatment.

Laparoscopic Heller myotomy relieves dysphagia in patients with achalasia and low LES pressure following pneumatic dilatation

Background: Although pneumatic dilatation is said to relieve dysphagia in achalasia if it decreases lower esophageal sphincter (LES) pressure to <10 mmHg, dysphagia persists in some cases. Performing a Heller myotomy in this setting has been challenged on the assumption that everything possible has already been done to eliminate the barrier posed by the malfunctioning sphincter. Therefore, we set out to assess the results of laparoscopic Heller myotomy and Dor fundoplication in achalasia in relation to LES pressure. Methods: Fifty-seven patients with achalasia were divided into the following three groups, based on the LES pressure and previous treatment: group A, previous balloon dilatation and LES pressure ?10 mmHg (n = 9); group B, previous balloon dilatation and LES pressure >10 mmHg (n = 23); group C, no previous balloon dilatation and LES pressure >10 mmHg (n = 25). All patients underwent a laparoscopic Heller myotomy and Dor fundoplication. The severity of dysphagia was gauged on a scale of 0-4. Results: In group A, LES pressure was 7 ± 2 mmHg preoperatively and 8 ± 3 mmHg postoperatively; the dysphagia score was 3.3 ± 0.7 preoperatively and 0.9 ± 1.1 postoperatively. Eighty-nine percent of patients had excellent or good results. In group B, LES pressure was 23 ± 8 mmHg preoperatively and 10 ± 1 mmHg postoperatively; the dysphagia score was 3.3 ± 0.7 preoperatively and 0.3 ± 0.5 postoperatively. All patients had excellent or good results. In group C, LES pressure was 23 ± 11 mmHg preoperatively and 14 ± 12 mmHg postoperatively; the dysphagia score was 3.6 ± 0.6 preoperatively and 0.2 ± 0.5 postoperatively. All patients had excellent or good results. Conclusions: These results show that (a) a LES pressure of <10 mmHg after pneumatic dilatation does not guarantee relief of dysphagia, and (b) laparoscopic Heller myotomy relieves dysphagia in most patients with a postdilatation LES pressure <10 mmHg. Thus, a laparoscopic Heller myotomy is indicated if dilatation does not relieve dysphagia, even if LES pressure has been decreased to <10 mmHg. Esophagectomy should be reserved for the occasional failure of this simpler operation. apd: 11 May 2001     

Laparoscopic approach for esophageal achalasia with epiphrenic diverticulum

We report the case of a 65-year-old woman with a 10-year history of dysphagia, regurgitation, cough, and 10-kg weight loss caused by an epiphrenic diverticulum associated with esophageal achalasia managed with a laparoscopic approach. A preoperative barium swallow showed a dilated sigmoid esophagus with a 6-cm epiphrenic diverticulum. Esophageal manometry confirmed the absence of peristalsis in the esophageal body. We performed a laparoscopic diverticulectomy and a 7-cm distal esophageal myotomy with a Dor fundoplication. The postoperative course was uneventful. On the third postoperative day a barium swallow showed no leak, and the patient started oral intake. She was discharged home 5 days after the operation free of symptoms and tolerating a soft diet. Sixteen months after surgery, she was asymptomatic and had gained 8 kg. A barium swallow showed a normal-size esophagus with regular emptying. We reaffirm the feasibility, safety, and efficacy of the laparoscopic diverticulectomy and distal myotomy with Dor fundoplication to manage epiphrenic diverticula resulting from esophageal achalasia.     

Hiatus calibration decreases postoperative dysphagia after laparoscopic fundoplication: case-report study

STUDY AIM: The risk of dysphagia after antireflux surgery seems to be increased with laparoscopy compared with open surgery. Calibration of the hiatus is usually done by the surgeon's finger during open surgery. The aim of this study was to assess the results of laparoscopic calibration with a Fogarty balloon catheter. PATIENTS AND METHODS: Between 1999 and 2001, 21 patients had a laparoscopic Toupet 240 degrees fundoplication with hiatus calibration using a 4 ml-inflated 8G Fogarty balloon catheter. These patients were compared with a group of 21 patients without hiatus calibration, matched for age, sex, preoperative dysphagia and esophageal dysmotility. Judgment criteria was early and/or late postoperative dysphagia (> 3 months). RESULTS: Median follow-up was 13 months. The rate of early dysphagia with and without calibration were 66% and 48% respectively (NS). Median duration of early dysphagia with and without calibration were 25 and 43 days respectively (p = 0.05). No patient with calibration had late dysphagia. One patient (5%) without calibration had unexplained late dysphagia for 2 years. He had preoperative esophageal dysmotility without oesophagitis. CONCLUSION: Hiatus calibration with a Fogarty balloon catheter decreased early postoperative dysphagia duration after Toupet laparoscopic fundoplication. This easily reproducible technical point standardizes the hiatus closure and should be recommended.     

Improved outcome after extended gastric myotomy for achalasia

HYPOTHESIS: There is general agreement that a Heller myotomy should extend 6 to 7 cm above the gastroesophageal junction. Results of most previous studies have recommended that the myotomy extend 1 to 1.5 cm below the gastroesophageal junction. We speculated that the effectiveness of the operation could be improved if a longer, 3-cm myotomy was carried out below the gastroesophageal junction, as it would more completely obliterate the lower esophageal sphincter. We, therefore, changed our technique in 1998. Concurrently, we converted from a Dor fundoplication to a Toupet fundoplication. This study analyzes the results of our new strategy. DESIGN: A case series using a prospectively maintained database. SETTING: Tertiary referral center. PATIENTS: One hundred ten consecutive patients with achalasia undergoing laparoscopic Heller myotomy. INTERVENTION: We analyzed the course of 52 patients treated with a standard laparoscopic esophagogastric myotomy (1.5 cm in the stomach) and a Dor fundoplication between September 1, 1994, and August 31, 1998, and 58 treated with an extended gastric myotomy (3 cm below the gastroesophageal junction) and a Toupet fundoplication between September 1, 1998, and August 31, 2001. MAIN OUTCOME MEASURES: Esophageal function testing (esophageal manometry and 24-hour pH monitoring), symptom questionnaire (frequency and severity), and postoperative interventions required. RESULTS: Postoperatively the lower esophageal sphincter pressure was significantly lower after extended gastric myotomy and a Toupet fundoplication vs standard myotomy and a Dor fundoplication (9.5 vs 15.8 mm Hg). Dysphagia was both less frequent (1.2 vs 2.1) and less severe (visual analog scale, 3.2 vs 5.3) after extended gastric myotomy and Toupet fundoplication. In the standard laparoscopic esophagogastric myotomy and a Dor fundoplication group, 9 patients (17%) had recurrent, severe dysphagia, which was treated by dilation in 5 patients and by reoperation in 4 patients. In the extended gastric myotomy and Toupet fundoplication group, 2 patients (3%) developed recurrent dysphagia that resolved with dilatation. There were no reoperations in the extended gastric myotomy and Toupet fundoplication group. No difference was noted in the frequency of heartburn (1.3 vs 1.7), regurgitation (0.3 vs 0.8), and chest pain (0.3 vs 0.6), nor was there a difference between the 2 groups in proximal (1.7% vs 2.3%) and distal (6.0% vs 5.9%) esophageal acid exposure. CONCLUSION: An extended gastric myotomy (3 cm) more effectively disrupts the lower esophageal sphincter, thus improving the results of surgical therapy for achalasia for dysphagia without increasing the rate of abnormal gastroesophageal reflux provided that a Toupet fundoplication is added.

??Laparoscopic anterior 180° partial fundoplication versus Nissen fundoplication in elderly patients with gastroesophageal reflux disease??A randomized controlled trial ZHAO Hong-zhi, QIN Ming-fang. Center of Tianjin Minimally Invasive Surgery, Nankai Hospital, Tianjin 300100, China
Corresponding author ??ZHAO Hong-zhi, E-mail??tjzhhzh@sina.com
Abstract Objective To compare two anti-reflux procedures??laparoscopic anterior 180° partial fundoplication and Nissen fundoplication??in elderly patients with gastroesophageal reflux disease (GERD). Methods From July 2008 to June 2012, 78 elderly patients with GERD were admitted in Tianjin Nankai Hospital. All the patients were allocated into two groups randomly. Thirty-nine patients were performed laparoscopic anterior 180° partial fundoplication (anterior 180° group) and the other 39 patients were performed Nissen fundoplication (Nissen group). Perioperative clinical parameters were recorded for comparing efficacy between two groups. Results Laparoscopic surgery was accomplished in all patients. The mean operation time of anterior180° group was significantly less than that of Nissen group (P<0.05). There was no significant difference of the mean duration of postoperative hospital stay between two groups (P>0.05). The symptoms in most patients were adequately relieved after operation. Endoscopy, radiology, esophageal manometry and 24-hour pH monitoring were repeated 1 month after surgery. All the results returned to normal compared with preoperative data. A total of 76 patients got follow-up. One patient was lost. One patient died of heart infarction. During follow-up period of 6-54 months (mean 28.5 months), there was no statistical significance between groups for the recurrence rate and satisfaction rate of operation. There was a lower incidence of dysphagia and epigastric bloating in the anterior 180° group. Conclusion For elderly patients with GERD??laparoscopic anterior 180°partial fundoplication has a good and durable anti-reflux effect compared with laparoscopic Nissen fundoplication. With shorter operation time and lower incidence of postoperative complications (dysphagia and epigastric bloating) compared with Nissen fundoplication, laparoscopic anterior 180°partial fundoplication can be employed as a more appropriate procedure for treatment of GERD in elderly patients.     

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.     

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.     

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.     

Minimally invasive surgery for achalasia: A 10-year experience

Minimally invasive esophagomyotomy for achalasia has become the preferred surgical treatment; the employment of a concomitant fundoplication with the myotomy is controversial. Here we report a retrospective analysis of 53 patients with achalasia treated with laparoscopic Heller myotomy; fundoplication was used in all patients except one, and 48 of the fundoplications were complete (floppy Nissen). There were no deaths or reoperations, and minor complications occurred in three patients. Good-to-excellent long-term results were obtained in 92% of the subjects (median follow-up 3 years). Two cases (4%) of persistent postoperative dysphagia were documented, one of which was treated with dilatation. Postoperative reflux occurred in five patients, four of whom did not receive a complete fundoplication; these patients were well controlled with medical therapy. We suggest that esophageal achalasia may be successfully treated with laparoscopic Heller myotomy and floppy Nissen fundoplication with an acceptable rate of postoperative dysphagia.
