Long-term results of laparoscopic antireflux surgery.

BackgroundIt is estimated that laparoscopic antireflux surgery has replaced the open approach in centers worldwide. Findings show it to be an established treatment option for chronic gastroesophageal reflux disease with an excellent clinical outcome and success rates between 85% and 95%. This prospective study aimed to evaluate surgical outcome and analysis of failure after 500 laparoscopic antireflux procedures followed up for as long as 5 years.MethodsBetween September 1993 and May 2000, 500 laparoscopic antireflux procedures were performed in our surgical unit. In 345 patients, a laparoscopic “floppy” Nissen fundoplication was performed, and in 155 patients, a Toupet fundoplication was carried out with standard mobilization of the upper part of the gastric fundus and with division of the short gastric vessels. Preoperative and postoperative data including 24-h pH monitoring, esophageal manometry, and analysis of failure were prospectively reviewed.ResultsConversion to open surgery was necessary in two patients (0.4%). Morbidity was 7%, including 24 patients (4.8%) for whom a laparoscopic redoprocedure was necessary because of failed primary intervention. There was no mortality. During a follow-up period of 3 months to 5 years, 24-h pH monitoring and esophageal manometry showed normal values in 95% of the patients including patients who had undergone redosurgery.ConclusionThe results of the current study demonstrate that laparoscopic antireflux surgery is feasible and effective, and that it can be performed safely without mortality and with low morbidity, yielding good to excellent results over a follow-up period up to 5 years.

Respiratory symptoms in patients with gastroesophageal reflux disease following medical therapy and following antireflux surgery.

BACKGROUND It is not known whether antireflux surgery is more effective than medical therapy to control respiratory symptoms (RS) in gastroesophageal reflux disease (GERD). METHODS In 21 GERD patients with RS, reflux was assessed by endoscopy, manometry, and pH monitoring. Patients had proton pump inhibitor therapy and cisapride for 6 months. After GERD relapsed following withdrawal of medical therapy, 7 patients with normal esophageal peristalsis had a laparoscopic Nissen fundoplication and 14 with impaired peristalsis a Toupet fundoplication. Respiratory symptoms were scored prior to treatment, at 6 months following medical therapy, and at 6 months after surgery. RESULTS Heartburn and esophagitis were effectively treated by medical and surgical therapy. Only surgery improved regurgitation. Respiratory symptoms improved in 18 patients (85.7%) following surgery and in only 3 patients (14.3%) following medical therapy (P <0.05). Esophageal peristalsis improved following the Toupet fundoplication. CONCLUSION Medical therapy fails to control reflux since it does not inhibit regurgitation. Surgery controls reflux and improves esophageal peristalsis, which contributes to its superiority over medical therapy in the treatment of RS associated with GERD.

Laparoscopic antireflux surgery: Tailoring the hiatal closure to the size of hiatal surface area

BackgroundThe closure of the hiatal crura has proven to be a fundamental issue in laparoscopic antireflux surgery. In particular, the use of prosthetic meshes for crural closure results in a significantly lower rate of postoperative hiatal hernia recurrence with or without intrathoracic migration of the fundic wrap. The aim of the present study was to evaluate different methods of crural closure depending on the size of the hiatal defect by measuring the hiatal surface area.MethodsFifty-five consecutive patients (mean age = 53 years) with symptomatic gastroesophageal reflux disease (GERD) were scheduled for laparoscopic antireflux surgery (LARS) in our surgical unit. Intraoperatively, the length, breadth, and diameter of the hiatal defect was measured using an endoscopic ruler. In every patient, the hiatal surface area (HSA) was calculated using an arithmetic formula. Depending on the calculated HSA, hiatal closure was performed by (1) simple sutures, (2) simple sutures with a 1 × 3-cm polypropylene mesh, (3) simple sutures with dual Parietex® dual mesh, or (4) “tension-free” polytetrafluoroethylene BARD Crurasoft® mesh.ResultsTwenty-six patients (47.2%) underwent laparoscopic 360° “floppy” Nissen fundoplication. The remaining 29 patients (52.8%) with esophageal body motility disorder underwent laparoscopic 270° Toupet fundoplication. Mean calculated HSA in all patients was 5.092 cm2. Thirty-two patients (58.2%) with a smaller hiatal defect (mean HSA = 3.859 cm2) underwent hiatal closure with simple sutures (mean number of sutures: = 2.0). In 12 patients (21.8%) with a mean HSA of 7.148 cm2, hiatal closure was performed with a 1 × 3-cm polypropylene mesh in addition to simple sutures. Five patients with a mean HSA of 6.703 cm2 underwent hiatal closure with Parietex mesh, and in the remaining six patients, who had a mean HSA of 8.483 cm2, the hiatus was closed using BARD Crurasoft mesh. For a mean followup period of 6.3 months, only one patient (1.8%) developed a postoperative partial intrathoracic wrap migration.ConclusionMeasurement of HSA with subsequent tailoring of the hiatal closure to the hiatal defect is an effective procedure to prevent hiatal hernia recurrence and/or intrathoracic wrap migration in laparoscopic antireflux surgery.

Laparoscopic Nissen fundoplication in patients with nonerosive reflux disease. Long-term quality-of-life assessment and surgical outcome.

BackgroundIt is known that laparoscopic antireflux surgery (LARS) can achieve an excellent surgical outcome including quality of life improvement in patients with erosive gastroesophageal reflux disease (GERD; EGD-positive). Less is known about the long-term surgical outcome in GERD patients who have no evidence of esophagitis (EGD-negative) before surgery. The aim of this study was to evaluate the surgical outcome in a well-selected group of EGD-negative patients compared to that of EGD-positive patients.MethodsFrom a large sample of more than 500 patients who underwent LARS, 89 EGD-negative patients (mean age, 51 ± 6 years; 56 males) were treated surgically because of persistent reflux-related symptoms despite medical therapy. In all cases, preoperative 24-h pH monitoring showed pathological values. To perform a comparative analysis, a matched sample of EGD-positive patients (mean age, 54 ± 10 years; 58 males) was selected from the database. Surgical outcome included for all patients objective data (e.g., manometry and pH data and endoscopy), quality of life evaluation [Gastrointestinal Quality of Life Index (GIQLI)] symptom evaluation, as well as patients’ satisfaction with surgery. The data of a complete 5-year follow-up are available.ResultsThere were no significant differences in symptomatic improvement, percentage of persistent surgical side-effects, or objective parameters. In general, patients’ satisfaction with surgery was comparable in both groups: 95% rated long-term outcome as excellent or good and would undergo surgical treatment again if necessary, respectively. Quality of life improvement was significantly better (p < 0.05) in the EGD-negative group because of the fact that GIQLI was more impaired before surgery (preoperative GIQLI, 81.7 ± 11.6 points/EGD-negative vs 93.8 ± 10.3 points/EGD-positive). Five years after surgery, GIQLI in both groups (121.2 ± 8.5 for EGD-negative vs 120.9 ± 7.3 for EGD-positive) showed comparable values to healthy controls (122.6 ± 8.5).ConclusionWe suggest that LARS is an excellent treatment option for well-selected patients with persistent GERD-related symptoms who have no endoscopic evidence of esophagitis.

Predictability of dysphagia after laparoscopic nissen fundoplication.

OBJECTIVE:Dysphagia is the most common complication of antireflux surgery. Temporary dysphagia occurs in addition to persistent dysphagia because of technical or physiological problems. Temporary dysphagia may be due to the patients personal perception or faulty eating habits. The aim of this study was to investigate the impact of the patients personality as it relates to temporary dysphagia and individual impairment.METHODS:Several studies have used the construct of personality known as “health locus of control” to predict health-related behavior and convalescence after medical or surgical treatments. This study investigates the predictability of the subjective degree of dysphagia and its perceived degree of impairment in relation to the health locus of control after laparoscopic so-called “floppy” Nissen fundoplication in 90 patients. Several questionnaires and single-item questions were given to the patients preoperatively, and 1 wk, 6 wk, and 3 months after surgery. The answers to the questions provided the data for this study.RESULTS:Preoperatively, 92% of the patients had no dysphagia and 8% had a mild subjective degree of dysphagia. Temporary postoperative dysphagia was found in approximately 50% of the patients 1 wk after surgery. The intensity of the dysphagia ranged among mild (18%), moderate (15%), and severe (16%). Three months postoperatively about 80% had no dysphagia and only 2% severe dysphagia. Correlations between the construct of personality and the intensity of postoperative dysphagia and its impairment revealed a significant relationship at all times. Patients with high expectations for their own health-related abilities (internal control) had less dysphagia (r =−0.78 after 1 wk [p < 0.001], r =−0.71 after 6 wk [p < 0.001], and r =−0.64 after 3 months [p < 0.001]), compared with patients who believed that their convalescence depended more on luck, chance, or fate (external control) (r = 0.67 after 1 wk [p < 0.01], r = 0.72 after 6 wk [p < 0.001], and r = 0.63 after 3 months [p < 0.01]). These results are highly significant. The correlation between health locus of control and the degree of a subjective impairment from perceived dysphagia showed similar results (p < 0.01).CONCLUSIONS:The subjective degree of dysphagia and the perceived impairment as a result of laparoscopic antireflux surgery can be predicted according to the personality of the patient. Those patients with low expectations for their own abilities can be identified before surgery, thereby allowing adaptation techniques to be applied that could improve the results and well-being of patients after antireflux surgery.

Dysphagia and quality of life after laparoscopic Nissen fundoplication in patients with and without prostetic reinforcement of the hiatal crura

BackgroundRecurrent hiatal hernia with or without intrathoracic wrap migration (“slipping Nissen”) is one of the most common complications after laparoscopic Nissen fundoplication (LNF). Therefore, we decided to reinforce the hiatal crura using a prostetic mesh prothesis in an attempt to reduce recurrent hiatal hernia.MethodsThe current nonrandomized study compares the surgical outcome, including quality of life data [Gastrointestinal Quality of Life Index (GIQLI)] and subjective degree of dysphagia, in a total of 200 patients with (n=100) or without (n=100) mesh prothesis for a follow-up for at least 1 year.ResultsThere are no significant differences between groups in postoperative DeMeester score or lower esophageal sphincter pressure. In the group without mesh prothesis, in 6 cases laparoscopic redo surgery was necessary due to severe and persistent dysphagia (n=2) or a slipping Nissen (n=4). Additionally, in 5 patients we found recurrent hiatal hernia, but patients have been without symptoms for at least 1 year. In the group with mesh prothesis, laparoscopic refundoplication was performed in only 1 patient due to a slipping Nissen. In this group, recurrent hiatal hernia was not found in endoscopy. After laparoscopic antireflux surgery, GIQLI showed an equal improvement in both groups with an outcome comparable to that for healthy individuals. Postoperative dysphagia was significantly higher in the group with mesh prothesis within the 3 first months after surgery. One year after surgery no differences could be found.ConclusionsOur findings suggest that LNF with reinforcement of the hiatal crura reduces the risk of recurrent hiatal hernia with or without wrap migration. In addition, LNF with mesh prothesis improves patient’s quality of life significantly to the same level as that in patients without mesh prothesis. Postoperative dysphagia is higher in the early period after surgery, but this is only temporary. Long-term results of a randomized tiral must be obtained before a general standardization can be discussed.

EAES recommendations for the management of gastroesophageal reflux disease

BackgroundGastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett’s esophagus, and enteroesophageal and duodenogastroesophageal reflux.MethodsThe European Association of Endoscopic Surgery (EAES) has tasked a group of experts, based on their clinical and scientific expertise in the field of GERD, to establish current guidelines in a consensus development conference. The expert panel was constituted in May 2012 and met in September 2012 and January 2013, followed by a Delphi process. Critical appraisal of the literature was accomplished. All articles were reviewed and classified according to the hierarchy of level of evidence and summarized in statements and recommendations, which were presented to the scientific community during the EAES yearly conference in a plenary session in Vienna 2013. A second Delphi process followed discussion in the plenary session.ResultsRecommendations for pathophysiologic and epidemiologic considerations, symptom evaluation, diagnostic workup, medical therapy, and surgical therapy are presented. Diagnostic evaluation and adequate selection of patients are the most important features for success of the current management of GERD. Laparoscopic fundoplication is the most important therapeutic technique for the success of surgical therapy of GERD.ConclusionsSince the background of GERD is multifactorial, the management of this disease requires a complex approach in diagnostic workup as well as for medical and surgical treatment. Laparoscopic fundoplication in well-selected patients is a successful therapeutic option.

Long-term follow-up after laparoscopic refundoplication for failed antireflux surgery: Quality of life, symptomatic outcome, and patient satisfaction

Quality of life and patient satisfaction have been shown to be important factors in evaluating outcome of laparoscopic antireflux surgery (LARS). The aim of this study was to evaluate data pertaining to quality of life, patient satisfaction, and changes in symptoms in patients who underwent laparoscopic redo surgery after primary failed open or laparoscopic antireflux surgery 3 to 5 years postoperatively. Between March 1995 and June 1998, a total of 27 patients whose mean age was 57 years (range 35 to 78 years) Underwent laparoscopic refundoplication for primary failed open or laparoscopic antireflux surgery. Quality of life was evaluated by means of the Gastrointestinal Quality of Life Index (GIQLI). Additionally, patient satisfaction and symptomatic outcome were evaluted using a standardized questionnaire. Three to 5 years after laparoscopic refundoplication, patients rated their quality of life (GIQLI) in an overall score of 113.4 points. Twenty-five patients (92.6%) rated their satisfaction with the redo procedure as very good and would undergo surgery again, if necessary. These patients were no longer taking any antireflux medication at follow-up. Two patients (7.4%) reported rare episodes of heartburn, which were managed successfully with proton pump inhibitors on demand, and four patients (14.8%) reported some episodes of regurgitation but with no decrease in quality of life. Seven patients (25.9%) suffer from mild-to-moderate dysphagia 5 years postoperatively, and 12 patients (44.4%) report having occasional chest pain but no other symptoms of gastroesophageal reflux disease. Nine of these patients suffer from concomitant cardiopulmonary disease. Laparoscopic refundoplication after primary failed antireflux surgery results in a high degree of patient satisfaction and significant improvement in quality of life with a good symptomatic outcome for a follow-up period of 3 to 5 years after surgery.

Dysphagia after laparoscopic antireflux surgery: a problem of hiatal closure more than a problem of the wrap.

BackgroundPostoperative dysphagia after laparoscopic antireflux surgery usually is transient and resolves within weeks after surgery. Persistent dysphagia develops in a small percentage of patients after surgery. There still is debate about whether postoperative dysphagia is caused by the type or placement of the fundic wrap or by mechanical obstruction of the hiatal crura. This study aimed to investigate patients who experienced recurrent or persistent dysphagia after laparoscopic antireflux surgery, and to identify the morphologic reason for this complication.MethodsA sample of 50 patients consecutively referred to the authors’ unit with recurrent, persistent, or new-onset of dysphagia after laparoscopic antireflux surgery were prospectively reviewed to identify the morphologic cause of postoperative dysphagia. According to their radiologic findings, these patients were divided into three groups: patients with signs of obstruction at or above the gastroesophageal junction suspicious of crural stenosis (group A; n = 18), patients with signs of total or partial migration of the wrap intrathoracically (group B; n = 27), and patients in whom the hiatal closure was radiologically assessed to be correct with a supposed stenosis of the wrap (group C; n = 5). The exact diagnosis of a too tight (group A) or too loose (group B) hiatus in contrast to a too tight wrap (group C) was established during laparoscopic redo surgery (groups B and C) or by x-ray during pneumatic dilation (group A).ResultsFor all 18 group A patients, intraoperative x-ray during pneumatic dilation showed the typical signs of hiatal tightness. Of these, 15 were free of symptoms after dilation, and 3 had to undergo laparoscopic redo surgery because of persistent dysphagia. In all these patients, the hiatal closure was narrowing the esophagus. All the group B patients underwent laparoscopic redo surgery because of intrathoracic wrap migration. Intraoperatively, all the patients had an intact fundoplication, which slipped above the diaphragm. Definitely, only in 10% of all 50 patients (group C) presenting with the symptom of dysphagia, was the morphologic reason for the obstruction a problem of the fundic wrap.ConclusionsIn most patients, postoperative dysphagia is more a problem of hiatal closure than a problem of the fundic wrap.

Lower recurrence rates after mesh-reinforced versus simple hiatal hernia repair: a meta-analysis of randomized trials.

Mesh hiatoplasty has been postulated to reduce recurrence rates, it is however prone to esophageal stricture, and early-term and mid-term dysphagia. The present meta-analysis was designed to compare the outcome between mesh-reinforced and primary hiatal hernia repair. The databases of Medline, EMBASE, and the Cochrane Library were searched; only randomized controlled trials entered the meta-analytical model. Anatomic recurrence documented by barium oesophagography was defined as the primary outcome endpoint. Three randomized controlled trials reporting the outcomes of 267 patients were identified. The follow-up period ranged between 6 and 12 months. The weighted mean recurrence rates after primary and mesh-reinforced hiatoplasty were 24.3% and 5.8%, respectively. Pooled analysis demonstrated increased risk of recurrence in primary hiatal closure (odds ratio, 4.2; 95% confidence interval, 1.8-9.5; P=0.001). Mesh-reinforced hiatal hernia repair is associated with an approximately 4-fold decreased risk of recurrence in comparison with simple repair. The long-term results of mesh-augmented hiatal closure remain to be investigated.
