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.     

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.     

Does Barrett's esophagus impact outcome after laparoscopic Nissen fundoplication?

BACKGROUND: This study was undertaken to compare patients with gastroesophageal reflux disease (GERD) with or without Barrett's esophagus for severity and frequency of symptoms and their response to antireflux surgery. METHODS: Eighty patients with GERD and Barrett's esophagus and 93 concurrent patients with GERD alone, all of whom underwent laparoscopic Nissen fundoplication, were compared by using symptom scores graded by a Likert scale. RESULTS: Before fundoplication, patients with Barrett's esophagus had higher DeMeester scores. Symptom scores were not different for patients with versus without Barrett's esophagus before or after laparoscopic Nissen fundoplication. CONCLUSIONS: Before and after fundoplication, patients with Barrett's esophagus, despite more severe reflux, have symptoms nearly identical in frequency and severity when compared with patients with GERD alone. Regardless of presence of Barrett's, all improve dramatically with laparoscopic Nissen fundoplication. Barrett's esophagus does not impact presentation before or outcome after laparoscopic Nissen fundoplication.     

Ten-year clinical outcome of a prospective randomized clinical trial of laparoscopic Nissen versus anterior 180( degrees ) partial fundoplication

Background:

A randomized trial of laparoscopic Nissen fundoplication and anterior 180° partial fundoplication was undertaken to determine whether the anterior procedure might reduce the incidence of dysphagia and other adverse outcomes following surgery for gastro‐oesophageal reflux disease. This study evaluated clinical outcomes after 10 years.

Methods:

Some 107 patients were randomized to undergo laparoscopic Nissen or anterior 180° partial fundoplication. Ten‐year data were not available for 18 patients. Information was obtained from 89 patients (48 Nissen, 41 anterior fundoplication) using a standard clinical questionnaire that focused on symptoms of reflux, potential postoperative side‐effects and overall satisfaction with the outcome of surgery.

Results:

There were no significant differences between the two groups with regard to reflux symptoms, dysphagia, abdominal bloating, ability to belch and overall satisfaction. Between 5 and 10 years after surgery, revisional surgery was required for reflux in two patients after anterior fundoplication. Two patients had revision after Nissen fundoplication, for reflux and recurrent hiatus hernia.

Conclusion:

Both laparoscopic anterior 180° partial and Nissen fundoplication are safe, effective and durable at 10 years' follow‐up. Most patients are satisfied with the clinical outcome. Copyright © 2008 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.     

Single center prospective randomized trial of laparoscopic Nissen versus anterior 90° fundoplication

Although Nissen fundoplication is a very effective treatment for gastroesophageal reflux, it is associated with a small incidence of troublesome postoperative side effects. To prevent this, progressive modification of surgical techniques has led to the development of an anterior 90° fundoplication. We undertook a prospective randomized trial to compare this procedure with Nissen fundoplication to determine whether it would achieve a better clinical outcome. Patients presenting to a single center for primary laparoscopic antireflux surgery were randomized to undergo either an anterior 90° fundoplication (n=40) or a Nissen fundoplication without division of the short gastric vessels (n=39). Clinical questionnaires were used to assess outcome at 1 month, 3–6 months, and 12 months. Both patients and the clinical interviewer were masked as to which procedure was performed. Follow-up with endoscopy, esophageal manometry, and pH monitoring was also undertaken. Operating time was similar for the two procedures (60 minutes for anterior vs. 55 minutes for Nissen fundoplication). Early postoperative complications were more common after Nissen fundoplication (18% vs. 5%). Two patients underwent laparoscopic reoperation for recurrent reflux after anterior 90° fundoplication, and four underwent laparoscopic reoperation after Nissen fundoplication (dysphagia, 3 patients; acute hiatus hernia, 1 patient). One year after surgery, dysphagia and other wind-related side effects were less common after anterior 90° fundoplication. Control of reflux symptoms and satisfaction with the overall outcome was similar for the two procedures. Anterior 90° fundoplication is followed by fewer side effects than Nissen fundoplication. This advantage is offset by a greater likelihood of reflux recurrence. However, this does not diminish patient satisfaction. Financial support for this study was provided from a project grant (no. 157986) from the National Heath and Medical Research Council of Australia (to D.I.W. and G.G.J.).     

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.     

Laparoscopic Nissen fundoplication is a good option in patients with abnormal esophageal motility

Background

Patients with gastroesophageal reflux disease (GERD) and abnormal esophageal motility are the most controversial subgroup of surgically treated patients because of potentially increased risk of postoperative dysphagia. Our study aim was to determine if Nissen fundoplication is associated with increased postoperative dysphagia in patients with ineffective esophageal motility.

Methods

Medical records of all adult (>18 years old) patients who underwent laparoscopic Nissen fundoplication for GERD over 8 years were reviewed retrospectively. Of the 151 patients, 28 (group A) met manometric criteria for abnormal esophageal motility (<30 mmHg mean contractile pressure or <80% peristalsis), whereas 63 (group B) had normal esophageal function. Sixty patients had no manometric data and were therefore excluded from analysis. Follow-up time ranged from 1 month to 5 years. Outcomes (postoperative dysphagia, recurrence of GERD symptoms, free of medications) were compared between groups.

Results

Group A had higher age and American Society of Anesthesiologists (ASA) score (p = 0.016 and 0.020), but this did not correlate with outcome. Two patients (7.1%) in group A and three patients (5.3%) in group B had postoperative dysphagia. When adjusted for follow-up time, there was no significant difference between the groups (p = 0.94). Group B had more cases of recurrent heartburn (10.7% versus 3.6%, p = 0.039), and more patients in this group were back on medications (21.4% versus 7.1%, p < 0.05)

Conclusions

This retrospective study found equally low rates of dysphagia following Nissen fundoplication regardless of baseline esophageal motility. Preoperative esophageal dysmotility therefore does not seem to be a contraindication for laparoscopic Nissen fundoplication.     

Predicting patient dissatisfaction following laparoscopic Nissen fundoplication: an analysis of symptoms

Background

Nissen fundoplication is a well-established treatment for gastroesophageal reflux disease (GERD) with a high success rate and a long-lasting effect. However, the literature reports that a persistent, small group of patients is not fully satisfied with the outcome. Identifying this patient group preoperatively would prevent disappointment for both patients and surgeon. This has proven difficult since dissatisfaction was related to nondisease-related factors instead of typical symptoms of GERD or the objective findings of investigations. We studied our series of patients who underwent laparoscopic Nissen fundoplication to identify predictors of patient dissatisfaction and the impact of surgery on individual symptoms.

Methods

All consecutive private patients undergoing Nissen fundoplication were asked to complete a preoperative and postoperative questionnaire concerning symptoms, medication use, and satisfaction. Demographics, investigations, complications, and reinterventions were documented. A standard laparoscopic Nissen fundoplication was performed.

Results

Over an 11-year period 222 patients underwent surgery for GERD. The postoperative response rate to the questionnaire was 77.5 %, with dissatisfaction reported by 12.8 % of the patients. Of these dissatisfied patients, only 13.6 % had proven disease recurrence. Both satisfied and dissatisfied patients presented with an inconsistent pattern of symptoms. None of the preoperative symptoms and investigations or the patient’s age and gender was predictive of postoperative dissatisfaction. Only postoperative heartburn, regurgitation, and bloating significantly correlated with patient dissatisfaction.

Conclusion

Nissen fundoplication has a very high satisfaction rate overall. A small percentage of patients are not fully satisfied and dissatisfaction is associated with reported persistent symptoms and side effects of surgery rather than gender or preoperative symptom pattern, severity of esophagitis, or total 24 h esophageal acid exposure.     

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.     

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.     

Causes of long-term dysphagia after laparoscopic Nissen fundoplication.

BACKGROUND: Laparoscopic fundoplication has revolutionized the surgical treatment of gastroesophageal reflux disease. Despite improvements in the technique of fundoplication, persistent dysphagia remains a significant cause of postoperative morbidity. METHOD: Causes of persistent postoperative dysphagia were analyzed in a consecutive series of 167 patients after laparoscopic Nissen fundoplication. Short gastric vessel division and its effect on postoperative dysphagia were analyzed. RESULTS: Follow-up was possible in 139 patients (83%). The mean follow-up period was 27 +/- 21 months. Nine patients (6%) had persistent (moderate to severe) dysphagia, and 33 patients (24%) had mild dysphagia. The satisfaction score among patients with persistent dysphagia was significantly lower than that in patients with mild dysphagia (P < 0.0002). On the other hand, the satisfaction rate among patients with mild dysphagia and those who are asymptomatic was similar. Manometry, performed in 7 of 9 persistent dysphagia patients revealed no difference in postoperative lower esophagus sphincter (LES) pressure and relaxation as compared with that in the control group (n = 52). Six of 9 patients with persistent dysphagia underwent a re-do antireflux procedure. Dysphagia as related to fundic mobilization (complete vs. partial) or bougie size (< 58 Fr. vs. > or = 58 Fr.) revealed no difference in the dysphagia ratings. CONCLUSIONS: Laparoscopic short Nissen fundoplication with or without fundic mobilization achieved an acceptable long-term dysphagia rate. Careful patient selection, identification of the short esophagus, and accurate construction of the fundoplication can lead to a decrease in the incidence of persistent postoperative dysphagia.     

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.     

Randomized double-blind trial of laparoscopic Nissen fundoplication versus anterior partial fundoplication

BACKGROUND: This double-blind, randomized study compared outcomes of laparoscopic Nissen total fundoplication and anterior partial fundoplication carried out by a single surgeon in a private practice. METHODS: All patients with proven gastro-oesophageal reflux disease, regardless of motility, presenting for laparoscopic antireflux surgery were randomized to either Nissen total or anterior partial fundoplication. Primary outcome measures were dysphagia and abolition of reflux. Secondary outcome measures were Visick scores, bloating, patient satisfaction and reoperation rate. RESULTS: Complete follow-up was available for 161 (98.8 per cent) of 163 patients (84 Nissen, 79 anterior). There were no differences in mean heartburn scores between groups. Recurrent reflux was observed in ten patients after anterior fundoplication, but none after the Nissen procedure. Dysphagia scores for both liquids and solids were lower after anterior fundoplication. Four patients had persistent troublesome dysphagia after Nissen fundoplication compared with none after anterior fundoplication. There were no differences between groups in postoperative bloating. The overall reoperation rate at 2 years was 7 per cent, all achieved laparoscopically. CONCLUSION: Nissen fundoplication cured reflux in all patients up to 2 years, but 5 per cent required revisional surgery. Recurrent reflux was more common after anterior fundoplication, but dysphagia was rare. Patient satisfaction was excellent in both groups. Revisional laparoscopic surgery was safe and usually successful.     

Laparoscopic conversion from Nissen to partial fundoplication for refractory dysphagia

Laparoscopic Nissen fundoplication is effective for treating gastroesophageal reflux and is usually well tolerated. Some patients, however, experience postoperative dysphagia refractory to conservative measures. We report our experience and operative technique for laparoscopic conversion of previous laparoscopic Nissen fundoplication to partial fundoplication to relieve dysphagia. We retrospectively reviewed the medical records of 6 patients with refractory dysphagia after laparoscopic Nissen fundoplication who underwent laparoscopic conversion to partial fundoplication using a laparoscopic linear stapler. There were no perioperative deaths and no fundoplication-related complications. In short-term follow-up, all patients reported improvement of dysphagia symptoms.     

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 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.     

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

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

Laparoscopic Cardial Calibration and Gastropexy for Treatment of Patients with Reflux Esophagitis: Pathophysiological basis and Result

Laparoscopic antireflux surgery is the gold standard procedure for treatment of patients with reflux esophagitis. The current results of the laparoscopic approach are absolutely comparables with the results obtained during the open surgery era. The Nissen, Nissen-Rossetti, or Toupet techniques are the more frequently used. We have performed cardial calibration and posterior gastropexy or Nissen fundoplication by the open approach with similar results. The purpose of this article is to present the anatomo-physiological basis for employing cardial calibration and posterior gastropexy in patients with reflux esophagitis. This study includes 108 symptomatic patients, 12 of them with associated extraesophageal manifestations ( posterior laryngitis). Endoscopic mild or moderate esophagitis was confirmed in 83 patients, Barrett’s esophagus in 12 patients, and type I or II hiatal hernia in 13 patients. All patients were also submitted to manometry, 24 hour intraesophageal pH monitoring, and barium swallow before and after surgery. Follow-up ranged from 12 to 36 months. There were no conversion, major intraoperative, or postoperative complications; nor were there any deaths. Postoperative dysphagia was present in 5% of cases. Symptomatic recurrence of reflux was observed in 10.3% and endoscopic presence of esophagitis in 12.3% of cases . Lower esophageal sphincter pressure increased significantly after surgery, even in patients with endoscopic recurrence. 24-hour intraesophageal monitoring improved after surgery, except in patients with objective recurrence of esophagitis. In conclusion, laparoscopic cardial calibration with posterior gastropexy presents comparable results to those reported after Nissen fundoplication and therefore could be another excellent therapeutic option in patients with reflux esophagitisThis paper was accepted for presentation as a free paper oral presentation for the last World Congress of ISS-SIC (cancelled).     

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.

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.
