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.

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.

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.

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.

Austrian experiences with redo antireflux surgery

BackgroundFrom 1996, the entire number of fundoplications performed in Austria increased dramatically, favoring the laparoscopic technique. Despite good results, some patients experience failure of antireflux surgery and therefore require redo surgery if medical therapy fails to control symptoms. The aim of the study was to describe the refundoplication policy in Austria with evaluation of the postoperative results.MethodsA questionnaire was sent to all Austrian surgical departments at the beginning of 2003 with questions about redo fundoplications (number, techniques, intraoperative complications, history, migration of patients, preoperative workup, mortality, and postoperative long-term complaints). It also included questions about primary fundoplications (number, technique, postoperative symptoms).ResultsOut of 4,504 primary fundoplications performed in Austria since 1990, 3,952 have been carried out laparoscopically. In a median of 31 months after the primary operation, 225 refundoplications have been performed, laparoscopically in the majority of patients. The Nissen and the partial posterior fundoplication were the preferred techniques. The conversion rate in these was 10.8%, mainly because of adhesions and lacerations of the spleen, the stomach, and the esophagus. The mortality rate after primary fundoplications was 0.04%, whereas the rate after refundoplications was 0.4%, all resulting from an open approach.ConclusionLaparoscopic refundoplications are widely accepted as a treatment option after failed primary antireflux surgery in Austria. However, the conversion rate is 6 times higher and the mortality rate is 10 times higher than for primary antireflux surgery. Therefore, redo fundoplications should be performed only in departments with large experience.

Is laparoscopic refundoplication feasible in patients with failed primary open antireflux surgery

Background: Due to the widespread availability and acceptance of minimal-access surgery, laparoscopic antireflux surgery has become the standard procedure for the treatment of severe gastroesophageal reflux disease (GERD). However, open and laparoscopic antireflux procedures sometimes result in failure, so that redosurgery is required in some cases. The aim of this prospective study was to evaluate the surgical outcome and quality of life of patients who underwent refundoplication after the failure of primary open antireflux surgery. Methods: Twenty patients with a mean age of 52 years (range, 33–69) underwent laparoscopic refundoplication after primary open antireflux surgery. Four of them had undergone surgery twice previously. Preoperative and postoperative data, including esophageal manometry, 24-h pH monitoring, and assessment of quality of life, were reviewed prospectively. Quality of life was evaluated using the Gastrointestinal Quality of Life Index (GIQLI). Results: In 18 patients (90%), the reoperation was completed successfully laparoscopically. Two others (10%) required conversion to an open procedure. One of them had an injury of the gastric wall; in the other case, severe bleeding of the spleen necessitated the conversion. The average operating time was 245 min. Preoperatively, the main symptoms were recurrent reflux in 14 cases and a combination of re-reflux and dysphagia in six cases. The anatomic findings were telescope phenomenon (n = 6), hiatal disruption (n = 10), and wrap breakdown (n = 4). Postoperatively, two patients suffered from dysphagia and required pneumatic dilatation. The lower esophageal sphincter (LES) pressure increased significantly from a preoperative value of 6.08 mmHg to 12.2 mmHg at 3 months and 11.9 mmHg at 1 year after surgery. The DeMeester score decreased from a preoperative value of 69.8 to 17.1 at 3 months and 14.6 at 1 year postoperatively. The GIQLI score increased from a preoperative value of 84.9 points to 119.6 points at 3 months and 120.1 points at 1 year. Conclusion: Laparoscopic refundoplication after the failure of a primary open intervention is an effective procedure that can be performed safely by experienced laparoscopic surgeon. The procedure yields excellent functional results and leads to significant improvement in the patients quality of life.

Quality of life and symptomatic outcome three to five years after laparoscopic Toupet fundoplication in gastroesophageal reflux disease patients with impaired esophageal motility

BACKGROUND Many centers practice a tailored approach to laparoscopic antireflux surgery in attempt to prevent postoperative side effects in gastroesophageal reflux disease (GERD) patients with an impaired esophageal motility. As a result of controversial findings reported in literature no worldwide accepted consensus exists regarding the appropriate indication for this tailored approach. The aim of this prospective study was to evaluate quality of life and symptomatic outcome in selected patients for a follow-up of 3 to 5 years. METHODS A total of 155 patients with esophageal dismotility underwent laparoscopic Toupet fundoplication (LTF). Basic requirements for surgery included in all patients a detailed evaluation of symptoms and quality of life (Gastrointestinal Quality of Life Index [GIQLI]), esophagogastroduodenoscopy, 24-hour pH monitoring, and esophageal manometry. Patients were evaluated 6 weeks, 3 months, 1 year, and 3 to 5 years after LTF. RESULTS GERD-related symptoms such as heartburn, regurgitation, dysphagia, or chest pain showed a significant improvement (P <0.05 to 0.001) in all gradings immediately after surgery. During the complete follow-up, a total of 4 patients (2.6%) required laparoscopic redo surgery because of recurrent GERD symptoms. Two patients (1.3%) were adequately maintained on short-term proton pump inhibitor therapy because of mild symptoms. All these patients have shown a pathological DeMeester score within the early period after surgery (3 months or 1 year control). Severe and persistent side effects have been present in 7 patients (4.5%), mild to moderate side effects in 11 patients (7.1%). Other side effects have been temporary and resolved spontaneously. GIQLI improved significantly (P <0.05 to 0.01) in all dimensions and persisted for at least 5 years with mean values comparable with healthy individuals. CONCLUSIONS LTF is effective, well tolerated, and improves quality of life, improving long-term outcome with an acceptable rate of long-term side effects in GERD patients with moderate to severe esophageal dismotility for a follow-up period of 3 to 5 years.

Measurement of the esophageal hiatus by calculation of the hiatal surface area (HSA). Why, when and how?

I read with great pleasure the ‘‘Letters to the editor’’ by Dr. Fourtanier and Dr. Reardon [1,2] regarding the problem of hiatal closure and particularly the definition and measurement of the hiatal defect. The growing discussion of this issue is distinguishing for its importance and relevance. The prevention of postoperative dysphagia caused by a too tight hiatal closure on the one hand as well as the prevention of a postoperative recurrent intrathoracic migration of the fundic wrap caused by inadequate crural closure on the other hand appears to be like being caught between a rock and a hard place. Undoubtedly, an exact and definite assessment of hiatal hernia size as well as a postoperative comparison of different hiatal closure techniques seems to be impossible as long as we perform the crural closure by our subjective estimation. Hence, I totally agree with Dr. Reardońs and Dr. Fourtanieŕs suggestion that there is a need for a standardized method for gauging the size of the hiatal defect and therefore allow an accurate comparison of crural closure techniques. As mentioned previously [2], the fundamental statement is that: [1] the closure of the hiatus is an important step of an antireflux procedure, [2] that calibration seems essential, and [3] particularly, it should be reproducible for all surgeons. A feasible device for hiatal calibration has been inaugurated by Dr. Fourtanier. With the HiaTech device (Laboratoire Surgical IOC Saint Etienne, France), a disposable instrument which is filled with 9ml serum and then passed through the hiatal orifice, a standardized method for hiatal closure seems to be available. This method appears to be a quick, simple and safe approach to a reproducible closure technique. However, the best way to get a maximum of information of the hiatal defect, and accordingly find the ideal diameter for closure of the hiatus, might be an exact definition of the real size of a hiatal hernia. In the same way as we do, Dr. Reardon recommends the measurement of the diameter of the hiatus by gauging the anteroposterior dimensions of the hiatus before closure, and consequently find an appropriate final diameter for adequate crural closure. In analogy to this method we have developed a method to define the size of the hiatal defect by calculating the so-called hiatal surface area (HSA), which should allow us to determine the two-dimensional expanse of the hiatal orifice and then adapt the crural closure to the exact dimension of the hiatal orifice. For measurement of the hiatal defect, an endoscopic ruler is brought intrabdominally. Firstly, the length of the crura is measured in centimetres beginning at the crural commisure up to the edge where the Pars flaccida begins (radius R). Then the circuit between the both crural edges are measured (s). With these two values, the angle of the crural commissure (a) is calculated using an inverse function (Figures 1 and 2):
