Nichterosive und erosive gastroösohageale Refluxerkrankung

BACKGROUND: The aim of this study was to evaluate long-term results of laparoscopic anterior semifundoplication in patients with nonerosive (NERD) and erosive (ERD) gastroesophageal reflux disease.PATIENTS AND METHODS: The study includes the period from May 1997 to July 2005. Upper gastrointestinal endoscopy was performed in all 190 patients. The severity of reflux esophagitis was classified according to Savary and Miller (grades I-IV). A standardized questionnaire was used for follow-up, and the modified symptomatic DeMeester score was assessed.RESULTS: 58.5 years of age (range 27-80), patients with nonerosive reflux disease (n=83) were significantly older than those with erosive reflux disease (n=107) (48 years range 15-84) (p=0.0001). Patients with NERD had a lower modified symptomatic DeMeester score postoperatively of 0 (range 0-4) than patients with ERD, of 1 (range 0-5), though without statistical significance (p=0.151).CONCLUSION: Laparoscopic anterior semifundoplication leads to comparable symptomatic long-term results in both NERD and ERD. Anterior semifundoplication is a good therapeutic option for selected patients with persistent reflux-associated symptoms and endoscopically negative esophagitis.     

Laparoscopic Gastric Banding and Crural Repair in the Obese Patient with a Hiatal Hernia

Background: A hiatal hernia is present in up to 50% of patients undergoing bariatric surgery. It has been claimed that laparoscopic adjustable gastric banding (LAGB) can both improve and induce reflux symptoms. The effect of a simultaneous crural repair and gastric banding has not yet been reported. Methods: Since 1999, all patients undergoing LAGB have a simultaneous crural repair if a hiatal hernia is present. Gastroesophageal reflux disease and dysphagia were assessed preoperatively and postoperatively using the modified DeMeester symptom-scoring system and the use of anti-reflux medication. Results: 62 patients with a hiatal hernia have undergone simultaneous LAGB and crural repair, with a median follow up of 14 (3-38) months. There was no mortality, and complications occurred in 3 patients, namely pulmonary embolus, slippage requiring repositioning of the band and persistent dysphagia requiring band removal. 24 months following LAGB and crural repair, median BMI had fallen from 43 to 31 kg/m² and median excess weight loss was 53%. Modified DeMeester symptom-score fell from a preoperative median of 3 (0-5) to a postoperative median of 0 (0-2) (P < 0.01, Mann Whitney U), and the number of patients on anti-reflux medication decreased from 44 to 6 (P < 0.01, Chi-squared). Conclusion: Crural repair in addition to LAGB does not increase the risk of slippage or dysphagia, significantly improves reflux symptoms and decreases the need for anti-reflux medication.     

Laparoscopic Dor-hemifundoplication for therapy of gastroesophageal reflux disease

INTRODUCTION: Gastroesophageal reflux disease is a major health problem in western industrial nations. Several prospective randomized studies showed the operative therapy of GERD superior to a steady medication with omeprazole regarding recurrence rate as well as rate of side effects. The today most performed 360 degrees fundoplication (Nissen-Rossetti) leads in 10-30% to a persisting postoperative dysphagia. We prefer the anterior semifundoplication by Dor. Aim of our study is to find out if our results are comparable to current literature and to open procedure. PATIENTS: Between 1.1.03 and 30.6.05 one operator performed on 100 consecutive patients (57 female, 43 male) between 29 and 86 years of age an anterior Dor-semifundoplication with posterior hiatal repair. In 37 cases we performed a cholecystectomy simultaneously, on two patients a sigmoid resection and in one case a left pancreatic resection. 52 Patients were re-evaluated after six months (median follow up nine months). RESULTS: Median operation time was 71 min (30-250 min). The learning curve showed a time reduction of initially 102 to 40 min in the last 10 cases. Blood loss was between 10 and 300 ml (median 40 ml). No conversion was necessary). As intraoperative complication in one case the right pleural cavity was opened. Postoperative complications were found to be wound infection in one case and urinary tract infection in another. Postoperative stay was four days (2-19 d) and eight days respectively for patients after sigmoid resection or left pancreatic resection. After median follow up of nine months 45 of 52 re-evaluated patients (86%) were free of reflux symptoms, 47 (90%) were pleased or very pleased with the result of the operation. Four patients felt at least a reduction of preoperative symptoms. CONCLUSION: The anterior Dor semifundoplication is a technically easy and low risk procedure, which has a lower side effect rate than the 360 degrees operation and will heal 90% of the patients from their reflux disease.     

Laparoscopic repair of chronic intrathoracic gastric volvulus

BACKGROUND: Totally intrathoracic gastric volvulus is an uncommon presentation of hiatal hernia, in which the stomach undergoes organoaxial torsion predisposing the herniated stomach to strangulation and necrosis. This may occur as a surgical emergency, but some patients present with only chronic, non-specific symptoms and can be treated electively. The aim of this study is to describe a comprehensive approach to laparoscopic repair of chronic intrathoracic gastric volvulus and to critically assess the pre-operative work-up. METHODS: Eight patients (median age, 71 years) underwent complete laparoscopic repair of chronic intrathoracic gastric volvulus. Symptoms of epigastric pain and early satiety were universally present. Five patients had reflux symptoms. The diagnostic evaluation included a video esophagogram, upper endoscopy, 24-hour pH measurement, and esophageal manometry in all patients. Operative results and postoperative outcome were recorded and follow-up at 1 year included a barium swallow in all patients. RESULTS: All patients had documented intrathoracic stomach. Five of 8 patients had a structurally normal lower esophageal sphincter. All 4 patients with reflux esophagitis on upper endoscopy had a positive 24-hour pH study, and 2 of these patients had a structurally defective lower esophageal sphincter on manometry. None of the patients had preoperative evidence of esophageal shortening. All procedures were completed laparoscopically. The procedure included reduction of the stomach into the abdomen, primary closure of the diaphragmatic defect, and the construction of a short, floppy Nissen fundoplication. There were no major complications. One patient required repair of a trocar site hernia 6 months postoperatively. At 1-year follow-up, there were no radiologic recurrences of the volvulus. One patient complained of temporary swallowing discomfort and another had recurrent gastroesophageal reflux disease (GERD) symptoms caused by a breakdown of the wrap. All other patients remained asymptomatic during follow-up. CONCLUSIONS: The repair of chronic gastric volvulus can be accomplished successfully with a laparoscopic approach. A preoperative endoscopy and esophagogram are crucial to detect esophageal stricture or shortening, and manometry is needed to access esophageal motility; pH measurements do not affect operative strategy. The procedure should include a Nissen fundoplication to treat preoperative GERD, to prevent possible postoperative GERD, and to secure the stomach in the abdomen. The procedure is safe but technically challenging, requiring previous laparoscopic foregut surgical expertise.     

Anterior semifundoplication in the treatment of gastroesophageal reflux disease: long-term results following conventional surgery]

INTRODUCTION: According to randomized studies, semifundoplication in the treatment of gastroesophageal reflux disease (GERD) is related to lower postoperative dysphagia rates than with fundoplication in comparable reflux controls. However there is a lack of long-term results. The object of this study was therefore to determine the influence of partial anterior fundoplication on the long-term clinical outcome (>1 year) in patients with GERD. METHOD: From December 1986 until May 2000, 100 patients suffering from GERD were operated on. Seven of them were not evaluated, four because of revisional surgery, two because of preceding multiple abdominal operations (MEN, colitis ulcerosa), and one because of Nissen fundoplication. In all, the perioperative results of 93 patients (51 men and 42 women aged 21 to 86 years) were evaluated. Fourteen patients died during the follow-up period and two were lost because of changes in address. Thus, 77 patients with a median follow-up of 88 months (range 15-94) were interviewed with a list of standardized questions concerning reflux control and dysphagia. RESULTS: The median operation time was 110 m (range 55-270). In one patient, an esophageal mucosal tear was detected intraoperatively and promptly repaired. Postoperatively, 71.4% (55/77) had no reflux complaints, 85.7% (66/77) had dysphagia, 66.2% took no further medication, and 31.2% (24/77) continued taking medication. The median interval free of symptoms was 25.5 months, and in 40.9% of the patients, symptoms recurred within the first year after operation. Five patients were in need of reoperation. A total of 77.9% of the patients were satisfied with the results of the operation. CONCLUSIONS: With regard to reflux control, long-term results of anterior semifundoplication are comparable to those of fundoplication. However, considering postoperative dysphagia, the technically easier anterior semifundoplication is less eventful and therefore a good alternative which in the long run shows good results after laparoscopic intervention.     

Postoperative symptoms and failure after antireflux surgery

BACKGROUND: Outcomes in patients having surgery for gastroesophageal reflux disease are most commonly determined by symptomatic assessment. Objective testing is usually reserved for symptomatic patients. HYPOTHESIS: To evaluate the relationship between symptomatic and objective outcomes after antireflux surgery. DESIGN: Retrospective analysis of prospectively collected data. SETTING: A tertiary care teaching hospital with a comprehensive esophageal physiology laboratory. INTERVENTIONS: A 360 degrees (Nissen) fundoplication or a 270 degrees (Toupet) posterior fundoplication was performed based on esophageal motility. Twenty-four-hour pH monitoring was used as a gold standard for assessing postoperative acid reflux. PATIENTS: Two hundred nine consecutive patients with preoperative and postoperative symptomatic and objective testing performed between January 1, 1996, and June 15, 2001. MAIN OUTCOME MEASURES: Data on preoperative and postoperative symptoms, DeMeester scores, and esophageal motility were prospectively collected. Objective testing was performed after at least 6 months. RESULTS: The preoperative median DeMeester score was 50.0 (interquartile [IQ] range, 30.3-87.0). One hundred eighty patients had a Nissen and 29 patients had a Toupet fundoplication. After a median postoperative interval of 7.7 months (IQ range, 6.7-9.5 months), 174 patients (83.3%) had normal DeMeester scores (median, 2.2; IQ range, 0.8-5.0; P<.001). Of 58 patients (27.7%) who had reflux symptoms after surgery, only 17 (29.3%) had abnormal DeMeester scores (median, 36.9; IQ range, 748.4-20.0; P =.001). Eighteen (11.9%) of the 151 asymptomatic patients had abnormal DeMeester scores (median, 32.5; IQ range, 22.2-57.5; P =.006). CONCLUSIONS: There is poor correlation between postoperative reflux symptoms and actual reflux (abnormal DeMeester scores). Surgeons must be careful to define their terms when reporting success or failure rates after antireflux surgery. Routine use of medical therapy for suppressing postoperative gastroesophageal reflux disease symptoms is not supported by these data, and postoperative therapy should be based on objective testing only.     

Relationship between symptom response and oesophageal acid exposure after medical and surgical treatment for gastro-oesophageal reflux disease

BACKGROUND: The relationship between symptom severity and objective evidence of gastro-oesophageal reflux disease (GORD) after medical and surgical treatment has recently been questioned. This study aimed to compare the symptomatic and physiological response (as measured by pHmetry) to the treatment of GORD by proton pump inhibitors (PPIs) and by laparoscopic antireflux surgery, and to examine the relationship between the patient's subjective and objective response to treatment of GORD. METHODS: Seventy patients underwent 24-h oesophageal pH measurement and DeMeester symptom assessment (for heartburn and regurgitation, grade 0-3) while off medical treatment, while taking PPIs and after laparoscopic fundoplication. RESULTS: The median percentage total time with oesophageal pH < 4 off treatment, during medical treatment and after fundoplication was 9.5, 4.3 and 0.5 per cent respectively. After medical treatment 30 patients became asymptomatic although 18 of these still had pathological reflux on pH testing. Of the 19 patients who remained symptomatic after surgery only two had pathological acid reflux. CONCLUSION: The symptomatic response of patients to either PPIs or antireflux surgery is a poor indicator of successful treatment in terms of reduced lower oesophageal acid exposure. A high proportion of patients whose symptoms are improved by PPIs still have pathological levels of acid reflux. Conversely, most patients who complain of reflux symptoms after antireflux surgery have no evidence of residual reflux on pHmetry.     

Symptomatic and functional outcome after laparoscopic reoperation for failed antireflux surgery

BACKGROUND: The aim was to determine symptomatic and functional outcome after reoperative antireflux surgery for recurrent reflux, persistent dysphagia and severe gas bloat, using a primarily laparoscopic surgical approach. METHODS: This was a retrospective analysis of prospectively collected data from 118 patients, of whom 70 had reoperative surgery for recurrent reflux, 35 for dysphagia and 13 for gas bloat. DeMeester scores before and 1 year after surgery, functional symptoms after surgery and overall patient satisfaction were analysed. RESULTS: Reoperation was completed laparoscopically in 101 patients (85.6 per cent), in 28 after previous open hiatal surgery. The operation was converted from an initial laparoscopic approach to open surgery in 17 patients. One-year follow-up data were available for 104 patients (88.1 per cent). After reoperation for recurrent reflux, 84 per cent had a DeMeester heartburn score of zero or one, and 87 per cent had a regurgitation score of zero or one. After reoperation for dysphagia, 21 of 32 patients had a dysphagia score of zero or one, with improvement observed in 25. All patients undergoing reoperation for severe gas bloat were satisfied with the outcome 1 year after operation. CONCLUSION: Revisional surgery for recurrent reflux using a laparoscopic approach offered high rates of success and patient satisfaction. Swallowing returned to normal in two-thirds of patients after reoperation.     

Comparison of three different procedures for antireflux surgery

BACKGROUND: No long-term comparisons of the various open and laparoscopic antireflux procedures have been undertaken. The aim of this study was to compare symptomatic outcomes of three procedures for antireflux surgery performed at three specialist units. METHODS: Patients undergoing open Nissen fundoplication, laparoscopic Nissen fundoplication and laparoscopic anterior partial fundoplication between December 1993 and February 2001 were identified. Patient outcome was assessed by means of a postal questionnaire. This was a hypothesis-generating study. RESULTS: Three hundred and fifty-seven patients (80.0 per cent) completed the questionnaire, with no differences in response rate between centres. Overall, a mean of only 7.6 per cent of patients reported a poor outcome. Logistic regression revealed no significant differences amongst the three procedures for any symptoms, after allowing for the effect of time. There was a general increase in the DeMeester score with increasing time from operation. The incidence of revisional reflux surgery was similar in the three groups. CONCLUSION: Medium-term symptomatic outcome following all three procedures was similar. There was some recurrence of symptoms of gastro-oesophageal reflux with time for all procedures, suggesting that the effects of surgery diminish with time. The level of experience of the surgeon in a particular operation was more important than the procedure performed.     

Laparoskopische partielle Fundoplicatio nach Toupet als generelle chirurgische Therapieform der gastrooesophagealen Refluxkrankheit 1-Jahresresultate einer auf 5 Jahre ausgelegten prospektiven Langzeitstudie

INTRODUCTION: A variety of laparoscopic antireflux operations exist for patients with gastroesophageal reflux diseases (GERD). Most surgeons operate using the concept of "tailored approach", which depends on esophageal motility. We have abandoned this concept because of the relatively high incidence of wrap-related complications in patients treated with laparoscopic Nissen fundoplication compared with patients treated with partial fundoplication. It is our policy to perform laparoscopic Toupet partial fundoplication in all patients suffering from GERD, independent of their esophageal motility. METHODS: In a prospective trial we have assessed and evaluated our 1-year results of the first 100 consecutive patients treated with Toupet partial fundoplication. All patients underwent esophagogastroscopy and 24-h pH manometry before operation. One third of patients (n = 34) underwent control manometry 8 weeks postoperatively. The patients were followed up clinically 1, 2, 6 and 12 months postoperatively. RESULTS: In this study group we achieved a healing rate in GERD of 97%. In 3% of patients GERD recurred. The median clinical DeMeester score decreased from 4.27 +/- 1.5 points preoperatively to 0.25 +/- 0.5 points 1 year postoperatively (P < 0.0005). The median fractional time with pH < 4 decreased from 17.8% +/- 12.5% preoperatively to 0.9% +/- 1.2% 8 weeks postoperatively (P < 0.0005). Because of persistent dysphagia 5% of our patients required postoperative dilatation therapy. The rate of reoperation and mortality was 0%. The total morbidity rate was 18%. In 50% of patients with preoperatively recorded esophageal motility disorder, an improvement of esophageal motility was found postoperatively. CONCLUSIONS: Our 1-year results encourage us to continue to perform laparoscopic Toupet partial fundoplication as the primary repair in all GERD patients, independent of their esophageal motility. Laparoscopic Toupet partial fundoplication has proven to be a safe and highly successful therapeutic option in these patients.     

Effect of laparoscopic antireflux operation on esophageal manometry, 24 hours pH-metry and quality of life in gastroesophageal reflux disease

It has been suggested that laparoscopic Nissen fundoplication is an effective procedure for the treatment of gastroesophageal reflux disease (GERD). Twenty-six patients with chronic gastroesophageal reflux disease underwent laparoscopic floppy Nissen fundoplication. 24 hours pH-metry, manometry and Gastrointestinal Quality of Life Index (GIQLI) questionnaire were done preoperatively, six-month and one year after the operation. The six weeks control investigation was limited to 24 pH-metry and GIQLI interview. Adequate reflux control was obtained in all patients, with reduction in acid reflux variables at six weeks, six months as well as at one year after the operation. Preoperative reflux index and DeMeester score was significantly higher than those we found postoperatively at both time period. Preoperative lower esophageal sphincter tone and length was abnormal on average. Both parameters increased significantly at six-month and one year after the operation. GIQLI also showed characteristic changes. Compared to preoperative values we found significantly higher GIQLI at both six-month and one year following surgery. Laparoscopic Nissen fundoplication provides an excellent symptomatic and physiologic outcome in patients with esophageal reflux disease.     

Results after laparoscopic fundoplication: does age matter?

Antireflux fundoplications are undertaken with hesitation in older patients because of presumed higher morbidity and poorer outcomes. This study was undertaken to determine if symptoms of gastroesophageal reflux disease (GERD) could be safely abrogated in a high-risk/reward popu lation of older patients. One hundred eight patients more than 70 years of age (range, 70-90 years) underwent laparoscopic Nissen fundoplications undertaken between 1992 and 2005 and were compared with 108 concurrent patients less than 60 years of age (range, 18-59 years) to determine relative outcomes. Before and after fundoplication, patients scored the severity of reflux and dysphagia on a Likert Scale (0 = minor, 10 = severe). Before fundoplication, older patients had lower reflux scores (P < 0.01), but not lower dysphagia scores or DeMeester scores. One patient (86 years old) died from myocardial infarction; otherwise, complications occurred infrequently, inconsequentially, and regardless of age. At similar durations of follow-up, reflux and dysphagia scores significantly improved (P < 0.01) for older and younger patients. After fundoplication, older patients had lower dysphagia scores (P < 0.01) and lower reflux scores (P < 0.01). At the most recent follow-up, 82 per cent of older patients rated their relief of symptoms as good or excellent. Similarly, 81 per cent of the younger patients reported good or excellent results. Ninety-one per cent of patients 70 years of age or more versus 85 per cent of patients less than 60 years would undergo laparoscopic Nissen fundoplication again, if necessary. With fundoplication, symptoms of GERD improve for older and younger patients, with less symptomatic dysphagia and reflux in older patients after fundoplication. Laparoscopic fundoplication safely ameliorates symptoms of GERD in elderly patients with symptomatic outcomes superior to those seen in younger patients.     

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.     

Die anteriore Semifundoplicatio zur Behandlung der gastroösophagealen Refluxkrankheit

Feasibility of surgical technique and evaluation of postoperative quality of life after laparoscopic treatment of intrathoracic stomach

Background Because of the risk of life-threatening complications, the discovery of a complete intrathoracic stomach demands urgent surgery with the aim of repositioning the stomach and gastropexy, and secondarily, to improve life quality. In this study the feasibility of surgical technique and postoperative quality of life after laparoscopic treatment of complete intrathoracic stomach has been evaluated.Methods From June 1999 to December 2001 16 patients with an intrathoracic stomach (hiatus hernia Types IIB and III) were treated by laparoscopic techniques, including the repositioning of the stomach, hemi-fundoplication and anterior gastropexy. During the postoperative follow-up the recurrence rate and quality of life (Eypasch index) were evaluated.Results All operations were performed laparoscopically without conversion, with a mean operating time of 155 min. Pleural injuries occurred in 31% of patients and pleural effusions in 38%, which required puncture in three cases. Complete follow-up showed no recurrences at a median of 14 months. The median quality of life index was 84.6 preoperatively and had significantly improved to 117.8 after the operation.Conclusion Laparoscopic access for the treatment of intrathoracic stomach represents a minimally invasive and safe treatment option for complete intrathoracic stomach, with a low level of perioperative morbidity and significant improvement in quality of life.     

Laparoscopic toupet fundoplication is an inadequate procedure for patients with severe reflux disease

Recently we have shown that laparoscopic Toupet fundoplication is associated with a high degree of late failure when employed as a primary treatment for gastroesophageal reflux disease (GERD). This study defines preoperative risk factors that predispose patients to failure. Data from 48 patients with objective follow-up performed as part of a prospective long-term outcomes project (24-hour pH monitoring, manometry, and esophagogastroduodenoscopy [EGD] at 6 months, 3 years, and 6 years) was analyzed. Preoperative studies of patients with documented postoperative failure (n = 22), defined as an abnormal 24-hour pH study (DeMeester score >14.9), were compared to preoperative studies of patients with normal 24-hour pH studies (n = 26). Outcomes were assessed at a mean of 22 months (range 18 to 37 months) postoperatively. Of the 22 patients in the failure group, 16 (77%) were symptomatic and the majority (64%) had resumed proton pump inhibitor therapy. Preoperative indices of severe reflux were significantly more prevalent in the failure group including a very low or absent lower esophageal sphincter (LES) pressure on manometry, biopsy-proved Barrett’s metaplasia, presence of a stricture, grade III or greater esophagitis, and a DeMeester score greater than 50 with ambulatory 24-hour pH testing. Comparison of pre- and postoperative manometric analysis of the LES revealed adequate augmentation of the LES in both groups and there were no wrap disruptions documented by postoperative EGD or manometry, indicating that reflux was most likely occurring through an intact wrap in the failure group. Esophageal dysmotility was present before surgery in four of the nonrefluxing patients and in three of the failures. Intact wraps were noted to have herniated in eight patients, all of whom had postoperative reflux. Laparoscopic Toupet fundoplication is associated with a high rate of failure both clinically and by objective testing. Surgery is more likely to fail in patients with severe GERD than in patients with uncomplicated or mild disease. A preoperative DeMeester score greater than 50 was 86% sensitive for predicting failure in our patient population. Laparoscopic Toupet fundoplication should not be used as a standard antireflux procedure particularly in patients with severe or complicated reflux disease.

A simplified technique for intrathoracic stomach repair: laparoscopic fundoplication with Vicryl mesh and BioGlue crural reinforcement

Background

Laparoscopic repair of an intrathoracic stomach has been associated with a high recurrence rate. The use of biologic or synthetic mesh to reinforce the crural repair has been shown to reduce recurrence. This study aimed to assess a simplified technique for reinforcing the crural repair using absorbable Vicryl mesh secured with BioGlue during laparoscopic repair of an intrathoracic stomach.

Methods

The charts of all patients who underwent laparoscopic repair of an intrathoracic stomach from June 2006 to March 2009 using the described technique were retrospectively reviewed. Intrathoracic stomach was defined as more than 50% of the stomach herniated into the chest. Follow-up assessment was routinely performed 1 year or more after surgery and included endoscopy, video esophagram, Bravo 48-h pH monitoring, and a gastroesophageal reflux disease (GERD)–health-related quality-of-life (HRQL) questionnaire.

Results

A total of 35 patients (male:female = 10:25) with a mean age of 70 years (48–89 years) and a mean body mass index (BMI) of 30.4 kg/m² (20.4–44.8 kg/m²) underwent repair using this technique. The median operating time was 144 min (101–311 min), and the median hospital stay was 2 days (1–21 days). There were three conversions (8.6%) and one intraoperative complication (2.9%). Three patients (8.6%) experienced postoperative complications. No mesh-related complications occurred. Follow-up assessment 1 year or more after surgery was available for 21 of the 25 eligible patients [median follow-up period, 14 months (11–34 months)]. There were two recurrences (9.5%), one of them asymptomatic. The median GERD-HRQL score was 5 (2–28). Nearly all the patients (91.3%) were satisfied with the operation, and 96% would have it again.

Conclusion

Vicryl mesh secured with BioGlue is a simple and easy method for reinforcing the crural closure during laparoscopic repair of an intrathoracic stomach. The recurrence rate at 1 year is low and comparable with that of other series using biologic mesh secured with sutures or tacks.     

Postoperative esophageal physiology studies may help to predict long-term symptoms following laparoscopic Nissen fundoplication

Background Laparoscopic Nissen fundoplication is an established treatment for gastroesophageal reflux disease (GERD). Postoperative improvement in esophageal physiology can be indicative of successful surgery, but the degree to which it correlates with symptom control remains questionable. We have performed this study to assess the utility of postoperative esophageal physiology studies in predicting long-term symptomatic outcome. Methods Between August 1997 and August 2003, 145 patients with symptomatic GERD underwent laparoscopic Nissen fundoplication as part of a randomized trial. Four months after surgery patients were invited to have postoperative esophageal physiology studies. In November 2005, a postal questionnaire was sent to all patients in order to assess reflux symptomatology (DeMeester symptom score). Results Completed symptom questionnaires were returned by 108 patients (74%) after a median of 5.7 years postoperatively. Linear regression of manometry data showed a significant correlation between the level of postoperative neosphincter pressure either above or below the median and long-term scores for heartburn (p = 0.03), dysphagia (p = 0.02), regurgitation (p = 0.01), and total symptom score (p = 0.002). In contrast, there was no evidence of a significant correlation between results of postoperative esophageal pH studies and symptom scores. Conclusion Postoperative physiology studies, particularly manometry, may be predictive of long-term symptoms following laparoscopic Nissen fundoplication.

Laparoscopic Nissen fundoplication ameliorates symptoms of reflux, especially for patients with very abnormal DeMeester scores

Intuitively, more severe acid reflux causes more severe symptoms. This study was undertaken to correlate preoperative DeMeester scores with symptoms before and after laparoscopic Nissen fundoplication. Before fundoplication, all patients with gastroesophageal reflux disease underwent 24 to 48 hour pH testing. Before and after fundoplication, the frequency and severity of reflux symptoms were scored using a Likert scale. Four hundred and eighty-one patients underwent fundoplication and were followed for a mean of 32 months. The preoperative median DeMeester score was 41 (range 14.8 to 361.5). Before fundoplication, DeMeester scores correlated with severity of gastroesophageal reflux disease symptoms (Spearman regression analysis, P < 0.05 for all). Postoperatively, all symptom scores improved (Wilcoxon matched pairs test, P < 0.05 for all). After fundoplication, preoperative DeMeester scores did not correlate with the frequency or severity of symptoms. For patients with excessive acid reflux, reflux severity impacts the frequency and severity of symptoms before fundoplication. Laparoscopic Nissen fundoplication improves the frequency and severity of all reflux symptoms. The severity of preoperative reflux does not impact the frequency or severity of symptoms after fundoplication. Relief of excessive acid reflux, regardless of severity or degree (i.e., DeMeester scores), ameliorates symptoms of acid reflux thereby encouraging fundoplication, especially for patients with very abnormal DeMeester scores.     

Laparoscopic anterior 90 degree fundoplication for reflux or large hiatus hernia

Anterior 90 degree partial fundoplication has been proposed as technique to minimize the risk of side-effects following surgery for gastro-oesophageal reflux. We have applied this approach for the treatment of gastro-oesophageal reflux and/or large hiatus hernias. Previous studies have shown that this type of procedure can achieve good control of reflux, with fewer side-effects. However, only short-term follow up has been reported. In this study, we determined later clinical outcomes in patients who have undergone this procedure. All patients who underwent a laparoscopic anterior 90 degree partial fundoplication surgery were identified from a database, which collected prospective clinical data. Patients completed a standardized questionnaire 3 months after surgery and then yearly to assess clinical symptoms of reflux and postoperative side-effects. Between February 1999 and January 2006, 246 patients underwent surgery--74 in conjunction with repair of a large hiatus hernia and 172 for reflux. Three patients underwent further surgery within 2 days of the original procedure (one for repair of a perforated oesophagus) and four underwent later surgical revision (reflux 3, dysphagia 1). Clinical follow-up data were available for 98% at 3-84 months (median 36). Most patients had effective relief of reflux symptoms at up to 3 years follow up. Dysphagia scores improved following surgery. The magnitude of this improvement was greater in patients with large hiatus hernias. More than 80% of the patients were able to belch normally at all time points after surgery and most were highly satisfied with the overall outcome. Satisfaction scores were higher following repair of a large hiatus hernia. The clinical results of laparoscopic anterior 90 degree fundoplication for either reflux or as part of repair of a large hiatus hernia are encouraging, although longer-term follow up is required to confirm durability of reflux control.
