Failure of antireflux surgery: causes and management strategies

Tension-free repair of hiatal hernia during laparoscopic fundoplication: a ten-year experience

BACKGROUND

The breakdown of a hiatal hernia repair can lead to clinical failure. The use of prosthetic material at the esophageal hiatus to strengthen the crural repair is relatively new and questions remain. This report examines the safety and efficacy of a tension-free crural repair with mesh.

PATIENTS AND METHODS

Since 1993, 135 consecutive patients (19-86) [9 re-do] completed laparoscopic tension-free hiatal hernia repair prior to Nissen wrap. Esophageal hiatus was patched with a PTFE mesh (first 112 patients) or a PTFE/ePTFE composite (23 patients) secured across the defect with staples to each crura. 130 patients completed a phone questionnaire during 2003/2004 (mean f/u 64 months).

RESULTS

There have been no short-term nor long-term infections related to the PTFE mesh. Symptoms were resolved or improved and resolved with meds in 122/130 (94%). Early re-herniation occurred in one patient after vigorous exercise.

CONCLUSIONS

Mesh repair/patch of the esophageal hiatus can be done without infection, with results similar to standard crural repair and consistent with surgical principles of non-tension.

Failed fundoplications

BACKGROUND

Five percent of patients who undergo fundoplication will require reoperation. The cause of this high failure rate and the best management for these patients remains poorly understood. The aim of this study was to identify patterns and causes of failure of primary antireflux procedures.

METHODS

Retrospective review of the medical records of patients who underwent revisional antireflux surgery at 2 tertiary referral centers.

RESULTS

Between 1998 and 2003, 39 patients underwent laparoscopic revisional antireflux surgery. The time between primary and revisional surgery was 5.9 +/- 0.4 years. Primary operations included 26 laparoscopic and 13 open fundoplications. All of the 39 revisional operations were attempted laparoscopically, and there was 1 open conversion. Revisional procedures included 31 Nissen and 8 partial fundoplications. The duration of surgery was 138 +/- 10 minutes. Length of hospital stay was 2.1 +/- 0.3 days. At a mean follow-up of 6 months, reflux resolved in 94% of patients. Morbidity occurred in 23% of patients. Four types of failure were identified: type 1 = herniation of the gastroesophageal junction through the hiatus with or without the wrap (n = 21); type 2 = paraesophageal hernia (n = 9); type 3 = malformation of the wrap (n = 2). Six patients had primary wrap failure, and 1 had esophageal dysmotility.

CONCLUSIONS

Laparoscopic revisional antireflux surgery is effective treatment for patients with failed primary fundoplications. Successful revisional surgery depends on identification and correction of the reason for primary fundoplication failure.

Reoperative laparoscopic fundoplication for the treatment of failed fundoplication

OBJECTIVE

This study was undertaken to determine the safety and efficacy of reoperative laparoscopic fundoplication for patients with failed fundoplication.

METHODS

Thirty-nine of 612 consecutive patients who had undergone fundoplication underwent laparoscopic reoperative fundoplication for recurrent symptoms, persistent dysphagia, or gas bloat. An additional 15 patients were referred from outside facilities for reoperation. Preoperative evaluation included barium swallow (n = 54), esophagogastroduodenoscopy (n = 54), esophageal manometry (n = 34), and 24-hour ambulatory pH measurement (n = 32). Symptom severity before and after surgery was evaluated with a visual analog scoring scale. The mean follow-up was 22.5 months.

RESULTS

The primary symptoms that led to reoperation in the 54 patients were heartburn (n = 26), dysphagia (n = 23), and gas bloat (n = 5). Average time from initial operation to reoperation was 22.7 months. There were 3 conversions to open technique. An anatomic reason for the failure of the initial fundoplication was found in 69% of cases: slipped or misplaced fundoplication (n = 14), disrupted fundoplication (n = 8), transdiaphragmatic herniation (n = 7), achalasia (n = 1), and tight fundoplication (n = 7). Fourteen patients had 15 perioperative complications. Mean hospital stay was 2.3 days. Symptoms such as heartburn, dysphagia, and gas bloat improved significantly after reoperation; 40% to 50% of patients had scores 0 to 2, 21% to 45% had scores 3 to 7, and 9% to 29% had scores 8 to 10. Proton-pump inhibitor use after operation decreased from 88% to 36%. Fifty-two percent of patients completely discontinued any antireflux medications. Three patients had failure of the reoperation and required additional procedures.

CONCLUSION

Laparoscopic reoperation for failed fundoplication is feasible and can achieve resolution of symptoms for a significant percentage of patients.

Late laparoscopic reoperation of failed antireflux procedures

Failures of antireflux procedures occur in 5% to 10% of the patients. Our objective is to report our experience with laparoscopic management of failed antireflux operations. Of 1698 patients who underwent laparoscopic treatment of gastroesophageal reflux disease (GERD), 53 were reoperations following either a previous open or laparoscopic antireflux procedure. The indications for surgical reoperation were persistent or recurrent GERD in 35 patients (66%), presence of paraesophageal hiatal hernia in 4 (7.5%), and severe dysphagia in 14 (26.4%). Hospital stay varied from 1 to 8 days, with an average of 1.2 days. Conversion to open laparotomy occurred in 10 patients (18.8%). The main causes for persistent or recurrent GERD were herniation (n=20) and disruption (n=12) of the fundoplication. Two patients had both herniation and disruption of the fundoplication. The main reason for severe dysphagia was tight hiatus. The most common reoperations were hiatal repair for hernia correction (n=26), redo fundoplication (n=16), and widening of the hiatus (n=12). Two patients had both hiatal repair and redo fundoplication. Intra (n=5) and postoperative (n=16) complications were frequent, but they were usually minor. There was no mortality. The present study demonstrated that laparoscopic reoperation for failed antireflux procedures may be performed safely in most patients with excellent result, low severe morbidity, and no mortality.

The Nissen fundoplication: indication, technical aspects and postoperative outcome

INTRODUCTION

Gastroesophageal reflux disease (GERD) is the most common foregut disease, with a great impact on quality of life and with intestinal, respiratory and cardiac symptoms and implications of carcinogenesis of the oesophagus. Medical therapy often fails, due to the complex pathophysiology of GERD. Surgery can cure the disease, since it is able to restore the anti-reflux barrier. It improves quality of life and prevents carcinogenesis.

METHODS

Review of the literature and presentation of our own experience and data in a series of more than 4,000 evaluated patients referred for suspected reflux disease, of whom 382 have been operated on.

CONCLUSION

The laparoscopic Nissen fundoplication is the most commonly used operation technique. It provides good long-term results in the majority of patients. However, due to an increase of outflow resistance of the oesophagus this operation is associated with some postoperative side effects. Therefore, alternative anti-reflux procedures may be indicated in selected patients.

The management of patients who have "failed" antireflux surgery

Gastroenterologists may be called upon to manage patients who have had antireflux surgery that failed. The available literature on this topic comprises predominantly reports on retrospective, observational studies written by surgeons who often have focused on how technical deficiencies in performing the operation led to the failure. Such reports are of limited value to the gastroenterologist seeking guidance on patient management. Furthermore, comparisons among the reports are confounded by the lack of a standardized definition for failed antireflux surgery. This report critically reviews the available literature, and suggests a practical approach to the management of patients who have symptoms that were not completely relieved, that reappeared later, or that were caused by antireflux surgery.

Endoscopic treatment of gastro-oesophageal reflux disease (GORD): a systematic review

Gastro-oesophageal reflux disease represents an extremely common disorder which has a substantial impact on patients' quality of life and use of health care resources. Gastro-oesophageal reflux disease is a chronic relapsing disease for which a lifelong solution is needed. Until now the two competing therapeutic modalities have been the medical and surgical therapies. Quite recently a third option has become available. A number of endoscopic anti-reflux procedures have been described, with the common goal of creating an anti-reflux barrier, thus obviating long-term proton pump inhibitors and the cost and potential risk of laparoscopic Nissen fundoplication. In this review the different techniques are thoroughly examined and the results are critically evaluated, giving special emphasis to efficacy, safety and durability of these new anti-reflux procedures. Available data show that these anti-reflux techniques produce significant improvement in gastro-oesophageal reflux disease symptomatology and quality of life as well as reduce the use of anti-reflux medication, without causing serious morbidity or mortality. However, the majority of these techniques have failed to adequately control oesophageal acid reflux. Endoscopic anti-reflux therapies therefore sound very attractive-being less invasive than surgery-and show a significant promise, but are still in the early stages of assessment. Large-scale randomized multi-centre trials comparing control groups with sham procedures are essential to confirm their efficacy. Further studies are also necessary to determine what modifications these techniques require in order to produce maximum clinical efficacy and durability. However, considering that current therapies (both medical and surgical) of gastro-oesophageal reflux disease are highly effective, the need for such new endoscopic modalities may be questionable. Moreover, appropriate trials in dedicated centres should be carried out to assure that the enthusiasm commonly associated with new technology is justified and can be generalized to open-access endoscopists.

Impact of anatomical wrap position on the outcome of Nissen fundoplication

BACKGROUND

The importance of anatomical reposition and fixation of the type I hiatal hernia during antireflux surgery has often been emphasized. It is not known whether the initial anatomical repair withstands the test of time and whether this repair is necessary for a successful outcome.

METHODS

The relationship between the objective anatomical and subjective symptomatic outcome of Nissen fundoplication was investigated prospectively in 57 patients. Findings of herniation, telescoping and obstruction at the level of the lower oesophageal sphincter on barium swallow were scored 2 years after operation by investigators who were unaware of the symptoms, and were related to symptoms and patient satisfaction evaluated by a standard questionnaire.

RESULTS

According to strict criteria, some 55 per cent of patients had some degree of anatomical failure; if only complete herniation, significant telescoping and signs of obstruction were scored as abnormal, 27 per cent had anatomical failure. There was no relation to subjective outcome; relief was reported by 48 of 49 patients, 25 of whom were cured and 23 significantly improved.

CONCLUSION

Anatomical repair during antireflux surgery does not stand the test of time. Although this has no demonstrable influence on the subjective outcome, the authors do not recommend deviating from well designed surgical guidelines. Current theories on the mechanism of antireflux surgery require further evaluation.

Results of surgical treatment for recurrent postoperative gastroesophageal reflux

The rate of recurrence of reflux esophagitis after classic antireflux surgery (fundoplication) is 10-15%. This rate is different in patients with esophagitis with and without Barrett's esophagus. We evaluated the clinical and laboratory findings in 104 patients with postoperative recurrent reflux esophagitis, determining the results of repeat antireflux surgery or an acid suppression-bile diversion procedure. Repeat fundoplication was performed in 26 patients, and truncal vagotomy, antrectomy, and Roux-en-Y gastrojejunostomy in 78 patients. Esophagectomy as a third operation was performed in seven patients. After repeat antireflux surgery, endoscopic evaluation demonstrated improvement of esophagitis in a small proportion of patients. Barrett's esophagus remained unchanged, and no regression of ulcer or stricture was observed. These complications improved significantly after acid suppression-bile diversion surgery. Incompetent lower esophageal sphincter (LES) was present in 55.8% after initial surgery and in 23% after reoperation. Acid reflux, initially present in 94.6% of patients, was also observed in 93.6% after fundoplication, 68.8% after redo fundoplication, and 16.6% after treatment with the acid suppression-bile diversion technique. A positive Bilitec test was present in 78% of patients before the operation and 56.6% after the repeat operation, and was negative after bile diversion surgery. Among 13 patients (50%) submitted to repeat surgery alone, esophagectomy as a third operation was necessary as a result of severe non-dilatable stricture in seven patients. Our conclusions are that repeat antireflux surgery alone failed to improve Barrett's esophagus complications and that the best results were obtained in patients submitted to acid suppression-bile diversion surgery.

Determining an appropriate threshold for referral to surgery for gastroesophageal reflux disease

BACKGROUND

Persistent symptomatic gastroesophageal reflux disease (GERD) can be treated with medication or surgery. The purposes of this study were (1) to determine how poor the quality of life on medication would need to be to justify assuming the risks of surgery, and (2) to estimate the proportion of patients currently on medication whose quality of life is below this value.

METHODS

We developed a Markov decision analysis model to simulate health outcomes (measured in quality adjusted life years [QALY]) over 10 years for medication and surgery in patients with typical GERD symptoms. We included probabilities of events obtained from a systematic literature review. Quality of life adjustments, expressed as utilities, were drawn from a survey of 131 patients 1 to 5 years after antireflux surgery. By using this model, we calculated what quality of life on medications would change the optimal strategy from medication to surgery (threshold). To determine the proportion of patients below this value, we prospectively surveyed 40 medically treated GERD patients at our hospital.

RESULTS

Surgery resulted in more QALYs than medical therapy when the utility with medication use was below 0.90. Sensitivity analysis showed this value to be relatively insensitive to reasonable variations in surgical risks (mortality, failures, reoperation) and quality of life after surgery. Among those surveyed on medications, 48% fell below this threshold and would be predicted to benefit from surgery.

CONCLUSION

Our model suggests that surgery would likely benefit a high proportion of medically treated GERD patients. Individual assessment of quality of life with GERD should be considered to aid clinical decision making.

Surgical and endoscopic treatment of gastroesophageal reflux disease

There is no evidence to advocate medical or surgical therapy as the best therapy for GERD. The decision to have antireflux surgery must be individualized. All patients taking long-term medications for GERD should receive advice on the safety and wisdom of staying on that therapy and information on antireflux surgery. Fundoplication should be considered in three circumstances [4]: 1. Patients who are intolerant of PPI therapy because of side effects should be considered for surgery. This situation will be less common now with five PPIs, however. 2. Patients who are poorly responsive to PPI therapy should be considered for surgery. This situation is probably not common, given the effectiveness of the currently available PPIs. It is more common in patients with atypical GERD. The gastroenterologist should be as certain as possible that the patient not only has GERD, but also that the patient's symptoms are reflux related. 3. Surgery should be considered when patients desire a permanent solution to free them of the need to take medications. These patients must be warned about the potential suboptimal results, including the frequent need for medication within a few years of having the procedure and the small but real possibility of becoming worse after the operation. Even in experienced hands, 1% to 2% of patients are worse after the procedure. A careful preoperative evaluation to ensure that the patient's symptoms are reflux related and that the right operative procedure is performed offers the patient the best opportunity for success. Widespread use of endoscopic therapy for GERD is probably still several years away. The best endoscopic therapy is yet to be determined, but it will need to be safe, effective, and easy to use.

Results of the Collis-Nissen gastroplasty to control reflux disease in patients who have Barrett's esophagus

Barrett's esophagus is an end-stage gastroesophageal reflux complication with a potential for malignant transformation. This condition probably is involved in esophageal cancer being perceived today as the most rapidly increasing cancer in Western countries. Numerous observations suggest that standard antireflux operations fail over time because of long-term inflammatory and fibrotic changes in the esophageal wall that cause shortening of the esophagus. The addition of esophageal elongation by gastroplasty provides a reliable repair by creation of a tension-free repair, whereas the durable antireflux effects are provided by the total fundoplication around the neoesophagus. The restored LES tone further helps control the mucosal damage and the chronic inflammatory changes. Complete regression of the abnormal mucosa still does not occur, and persistent irritation of that mucosa still entails the risk for progression toward dysplasia. The natural history of the columnar-lined mucosa in BE may be altered by medical or surgical intervention. It is too early to judge in which settings these interventions will be meaningful.

Surgical clips to help identify anatomy after a Nissen fundoplication

Laparoscopic fundoplication has had a remarkable growth in the treatment of gastroesophageal reflux disease. But a failure rate of more than 5% has led to increasing numbers of patients with recurrent symptoms presenting for corrective surgery. A simple technique of placing surgical clips on the sutures used to place the wrap helps identify the anatomy during contrast studies and helps plan for corrective surgery.

Obesity adversely affects the outcome of antireflux operations

BACKGROUND

We hypothesized that obesity was associated with long-term failure of antireflux procedures, and that in obese patients antireflux operations were easier to perform via thoracotomy, and therefore likely to have a higher success rate than transabdominal (laparoscopic or open) antireflux procedures. The aims of this study was to determine the impact of obesity on the success of antireflux operations, and to compare the success rates of transthoracic and laparoscopic approaches in obese patients with gastroesophageal reflux.

METHODS

The records of 224 consecutive patients undergoing antireflux surgery by two surgeons in a university-based tertiary care center were reviewed and patients contacted for follow-up assessment. The patients were classified into groups based on the type of operation performed and the calculated body mass index (BMI): normal (BMI 30). Recurrences were documented by symptoms responsive to acid-suppressive medication and radiologic or pH probe studies.

RESULTS

Among the 224 patients included in this study, 187 underwent laparoscopic Nissen fundoplications (LNF) and 37 underwent Belsey Mark IV(BM4) procedures. The mean follow-up period was 37 months. The three groups included 89 (39.7%) patients classified as having normal weight, 87 (38.8%) as overweight and 48 (21.4%) as obese. Normal, overweight, and obese patients were similar in terms of age, gender, hiatal hernia size, degree of esophagitis, and comorbid conditions. A total of 26 recurrences occurred, giving an overall recurrence rate of 11.6%. There were 4 recurrences in the normal group (4.5%), 7 in the overweight group (8.0%; p not significant vs normal), and 15 in the obese group (31%; p < 0.001 vs normal; p <.001 vs overweight). The recurrence rate was similar between LNF and BM4 in each BMI subgroup, although in aggregate, the recurrence rate after BMW was greater than after LNF (10/37 vs 16/187; p < 0.02).

CONCLUSIONS

Obesity adversely affects the long-term success of antireflux operations. Although athoracotomy provides optimal exposure of the hiatal structures in obese patients, a transthoracic approach was associated with a higher recurrence rate than LNF. Given the high failure rate of antireflux operations in obese patients, intensive efforts at sustained weight loss should be made before consideration of surgery.

Analysis and surgical treatment of persistent dysphagia after Nissen fundoplication

BACKGROUND

After Nissen fundoplication, troublesome dysphagia develops in 5-10 per cent of patients. The mechanism of dysphagia has not been fully resolved, in spite of a number of studies focusing on oesophageal motility and lower oesophageal sphincter (LOS) dynamics. Tightness and length of the wrap have had considerable attention, without giving a fully satisfactory explanation of the pathophysiological mechanism.

METHODS

Eighteen patients with persistent dysphagia after Nissen fundoplication needing reoperation were studied. Eighteen patients, matched for age and sex, without dysphagia after Nissen fundoplication were used as controls. Reoperation consisted of conversion of a 360 degrees into a 270 degrees wrap. Barium swallow, endoscopy, oesophageal manometry and 24-h pH monitoring were performed before and after (re)operation.

RESULTS

Peristaltic amplitude, velocity and duration of contraction were not significantly influenced by operation. In 16 of 18 patients with dysphagia, LOS relaxation was incomplete and the residual relaxation pressure was significantly higher than that in the group without dysphagia (P < 0.01). No correlation was found between LOS pressure and peristaltic amplitude, nor between LOS pressure and ramp pressure in the distal oesophagus. After reoperation, basal LOS pressure decreased significantly (P < 0.01) and LOS relaxation was complete in all but three patients; residual relaxation pressure decreased (P < 0.01) and was significantly lower than that after uncomplicated Nissen fundoplication. In the latter group, LOS pressure, residual relaxation pressure and ramp pressure increased significantly after operation (P < 0.01).

CONCLUSION

A return to complete LOS relaxation and a decrease in residual relaxation pressure play an important role in resolving dysphagia.

Quality of life before and after laparoscopic Nissen fundoplication

BACKGROUND

Gastroesophageal reflux disease (GERD) is a common disorder in the Western world. The acute disease can usually be managed by medical therapy. To prevent relapse, many patients require lifelong medication. In these patients, laparoscopic antireflux surgery offers a good alternative. The aim of this study was to evaluate the postoperative results and compare pre- and postoperative quality of life after laparoscopic Nissen fundoplication.

METHODS

Clinical investigations, including esophageal manometry, pH monitoring, and endoscopy, and a previously validated Quality of Life Index, were performed before and a median of 41 month after antireflux surgery in 75 patients.

RESULTS

After laparoscopic Nissen fundoplication, the percentage of total time with pH <4 decreased from 10.4% to 3.2% on 24-h pH monitoring. The mean pressure of the lower esophageal sphincter improved from 8.1 to 12.3 mmHg. Esophagitis healed in 63 of 66 patients in whom it was present prior to surgery. The overall Quality of Life Index improved significantly from 86 +/- 16 to 116 +/- 16.

CONCLUSION

Laparoscopic fundoplication provides effective and durable relief of reflux in patients with GERD. The Quality of Life Index showed significant improvement after surgery.

Esophagogastric fistula secondary to teflon pledget: a rare complication following laparoscopic fundoplication

Laparoscopic fundoplication has become the standard operation for gastroesophageal reflux disease. In our service, a laparoscopic fundoplication is performed as a 2-cm floppy 360 degrees wrap with division of the short gastric vessels and the fundoplication is sutured using a prolene 2/0 mattress suture (Ethicon, USA) and buttressed laterally with two teflon pledgets (PTFE 1.85 mm; low porosity, Bard, USA). We report a patient with post-operative dysphagia due to an esophagogastric fistula caused by erosion of a teflon pledget. This is the first such case in 734 laparoscopic fundoplications performed between January 1991 and December 1998. Reoperation was required, resulting in a prolonged convalescence. A review of current literature has not revealed any similar cases. Causes for this rare complication are postulated.

Psychiatric disorders affect outcomes of antireflux operations for gastroesophageal reflux disease

BACKGROUND

Most of the information used to determine a patient's candidacy for antireflux surgery has centered on physiologic measurements of esophageal functioning and quantitative assessment of acid reflux. Unfortunately, little attention has been paid to the study of psychosocial factors that could affect outcomes. The purpose of this study was to establish whether concomitant psychiatric disorders might affect the symptomatic outcomes of antireflux surgery.

METHODS

We retrospectively reviewed a prospectively gathered database of patients with gastroesophageal reflux disease (GERD) who underwent either open or laparoscopic antireflux surgery. A history of a psychiatric disorder was considered to be present if the patient had been previously diagnosed with a DSM-IV psychiatric diagnosis and was being medically treated for it. Preoperatively, patients were evaluated with the symptom severity questionnaire, the GERD-HRQL (best score 0, worst score 50). Later in the series, patients were also evaluated with the generic quality-of-life questionnaire, the SF-36 (best score 100, worst score 0). After antireflux surgery, patients completed both questionnaires 6 weeks postoperatively.

RESULTS

A total of 94 patients underwent antireflux surgery. Seventy-seven of them had laparoscopic antireflux surgery (either Nissen or Toupet fundoplication), and 17 had open antireflux surgery (Nissen, Toupet, Collis-Nissen, or Belsey fundoplications). Nine patients had psychiatric disorders (five major depression, four anxiety disorders). At 6-week follow-up, 95.3% of patients without psychiatric disorders were satisfied with surgery, as compared to 11.1% of patients with psychiatric disorders (p < 0.000001). Patients satisfied with surgery had a median SF-36 mental health domain score of 76, as compared to a score of 36 for patients dissatisfied with surgery (p = 0.0002). Patients without psychiatric disorders showed improvement in the median total GERD-HRQL score from 27 preoperatively to 1 postoperatively (p < 0.000001), whereas patients with psychiatric disorders demonstrated less improvement, from 30 preoperatively to 10.5 postoperatively (p = 0.03).

CONCLUSIONS

Patients with psychiatric disorders are rarely satisfied with the results of antireflux surgery. Moreover, these patients demonstrated less symptomatic relief than patients without psychiatric disorders. Patients who were dissatisfied with antireflux surgery--even those without psychiatric disorders--had lower scores on the SF-36 mental health domain. These results suggest that even patients who might otherwise be candidates for antireflux surgery may have a poor symptomatic outcome, if they also have low mental health domain scores. Antireflux surgery in patients who suffer from major depression or anxiety disorder should be approached with great trepidation.

Anti-reflux surgery in the laparoscopic era

The introduction of laparoscopic anti-reflux surgery has led to a renewed interest in the operative treatment of gastro-oesophageal reflux disease (GORD). Three groups of patients can be identified who are particularly suited to laparoscopic anti-reflux surgery. Failure to respond to medical treatment has been historically the main determinant for those referred for anti-reflux surgery. With the availability of modern anti-secretory drugs most patients with chronic GORD can control their symptoms adequately by these means. Even effective medical therapy, however, is not without problems. In many patients rapid and consistent relapse of symptoms and oesophagitis occurs on cessation of therapy. Some of these patients do not want to be reliant on a form of medication that has yet to firmly establish its record for safety over many years of continued use. A second readily identifiable group of patients are those who are often described as 'volume refluxers'. They are bothered by persistent fluid regurgitation despite adequate control of their heartburn with acid suppressive drugs. Third there are those individuals who develop oesophageal strictures and those with Barrett's oesophagus and concomitant reflux symptoms and also those with respiratory complications associated with presumed aspiration of gastric juice into the pharynx and into the respiratory tree. The low morbidity associated with laparoscopic surgery that has been achieved in the best modern series means that the pendulum may swing back to surgery and therefore it is even more important that the right operation (fundoplication) is done for the right patient. Failure to create an adequate crural repair behind the wrap is associated with a risk of early post-operative para-oesophageal herniation and proximal wrap migration. The question of tailored anti-reflux surgery based on the pre-operative motor function of the body of the oesophagus is widely applied, although the scientific basis for these selective approaches is rather weak. Partial fundoplication seems to be associated with very low rates of dysphagia and of gas bloat. Assessment of the post-operative result should ideally be done by an independent observer and should consider not only traditional outcome measures but also the impact of surgery on the quality of the patient's life. Investigations on the cost effectiveness of these surgical therapeutic strategies suggest important benefits of surgery, which should be incorporated into the clinical decision process when assessing different long-term management alternatives for patients with chronic GORD.

Laparoscopic esophageal surgery

In its 9-year history, laparoscopic esophageal surgery has become second only to gallbladder surgery in the frequency of minimally invasive procedures performed in routine surgical practice. Laparoscopic fundoplication has assumed a central role in the surgical treatment of gastroesophageal reflux. Laparoscopic myotomy has emerged as the optimal form of therapy for achalasia, and staging laparoscopy has been identified as an important adjunct to the preoperative evaluation of esophageal and gastroesophageal junction carcinoma. Laparoscopic paraesophageal hernia repair and remedial laparoscopic antireflux surgery currently are gaining acceptance. Laparoscopic gastroplasty, esophagectomy, and diverticulectomy are undergoing clinical trials, and their roles remain to be defined.

Minimally invasive approaches to antireflux surgery

Gastroesophageal reflux disease is one of the most common disorders affecting western civilization. Historically, surgical antireflux therapy was reserved for patients who had failed medical therapy, typically in the presence of refractory ulcers or difficult-to-manage strictures. More recently, with improvements in acid control, these acid-pepsin-related complications of reflux have been replaced by the malignant complications of reflux disease, with emphasis now on total control of reflux. Recent developments in surgical technique and the demonstrated effectiveness of a variety of minimally invasive treatment options have changed our approach to these patients. This article summarizes the recommended diagnostic evaluation of patients with reflux symptoms and the current indications for antireflux surgery. The techniques of commonly performed minimally invasive antireflux procedures are described along with a review of the results to be expected. Future prospects for improving the management of reflux are discussed; these include recently described nonsurgical methods for restoring competency to the lower esophageal sphincter.

Accurate placement of the esophageal pH electrode for 24-hour pH monitoring using a combined pH/manometry probe

OBJECTIVE

Accurate placement of a pH electrode requires manometric localization of the lower esophageal sphincter (LES). Combined manometry/pH devices using water-perfused tubes attached to pH catheters and the use of an electronic "LES locator" have been reported. We investigated whether accurate placement of pH probes can be achieved using such a probe, and whether this may reduce the need for the performance of the usual stepwise pull-back manometry.

METHODS

Thirty consecutive patients (15 men, 15 women; median age, 56 yr; interquartile range, 42-68 yr) referred for manometry and pH testing were included in the study. The localization of the LES was determined with standard esophageal manometry. After that, a second 3-mm pH electrode with an internal perfusion port was passed into the stomach. Using this catheter, a single stepwise pull-through manometry was performed and the LES position was noted. LES location, mean pressure, and length obtained with standard manometry were compared to data from the combined pH/manometry catheter. Additionally the time necessary to perform each of the procedures was noted and the patient's discomfort caused by the catheter was evaluated using a standardized questionnaire.

RESULTS

The LES location with the pH/manometry probe was proximal to that with standard manometry in 19 patients (63%), the same in nine patients (30%), and distal in two patients (7%). The differences were <2 cm in 29 of 30 (97%) patients. The LES location with the pH/manometry probe required a median of 6.5 min (interquartile range: 3.5-8.5 min) versus a median of 21.5 min (interquartile range: 14.5-26.5 min) for standard manometry (p < 0.0001). In addition, LES evaluation using the combined pH/manometry probe provided accurate data on the resting pressure, as well as overall and intraabdominal length of the LES. All patients tolerated the combination probe better than the standard manometry probe (p < 0.001).

CONCLUSIONS

Placement of the esophageal electrode for 24-h esophageal pH monitoring using a combined pH/manometry probe is accurate. The technique is simple, time-saving, and convenient for the patients. Because it is possible to accurately evaluate the LES using this technique, it may even replace conventional manometry before pH probe placement.

Life after antireflux surgery

Laparoscopic fundoplication technique has become the operative modality of choice for antireflux surgery. An increasing number of patients and physicians have enthusiastically embraced this "minimally-invasive" technologic development for treatment of gastroesophageal reflux disease (GERD). However, laparoscopic fundoplication has been frequently advertised as the therapeutic solution for all GERD patients. Subsequently, the number and severity of complications resulting from laparoscopic surgery--often performed indiscriminately--has increased dramatically. This article reviews the efficacy of the laparoscopic fundoplication operation for GERD based on current, relatively short-term reports from centers specializing in this treatment modality. The majority of these reports are very positive. Unfortunately, the results of fundoplication operations performed by community surgeons are unknown. There are a number of disturbing factors relating to laparoscopic treatment for GERD that should raise a red flag of caution to the medical community, particularly primary-care physicians and their patients. The central portion of this report devotes itself to discussing the problems associated with this new minimally-invasive technique for fundoplication operations. These problems include the selectivity of current reports on outcomes of the laparascopic fundoplication operation and the lack of uniform data acquisition associated with these postoperative studies. The technical difficulties of the laparascopic fundoplication surgery are discussed, and the need for operator expertise and appreciation of esophageal physiology and anatomy are stressed. Finally, the long-term durability of the fundoplication wrap is questioned and the morbidity associated with the operation--particularly dysphagia--is addressed. In the final segment, the complications encountered after laparoscopic fundoplication operations are detailed and the techniques for evaluating the symptomatic postfundoplication patient are discussed. Laparoscopic fundoplication operation is good therapy in an appropriate clinical setting when performed by a well-trained and experienced surgeon. However, the operation should not be first-line therapy for the majority of GERD patients. An esophagus disabled by an inappropriate or dysfunctional fundoplication wrap is a terrible price to pay for control of acid reflux.

Laparoscopic anti-reflux surgery in New Zealand: a trend towards partial fundoplication

BACKGROUND

The advent of laparoscopic anti-reflux surgery has generated considerable debate regarding the best technique. The present study was undertaken to determine the trends and current technique in laparoscopic anti-reflux surgery in New Zealand.

METHODS

A confidential nationwide postal survey was sent to all general surgeons in New Zealand; it was repeated after a month, and followed up with a telephone prompt, if necessary.

RESULTS

Of the 146 questionnaires sent out, 126 were returned (response rate: 86%), and 104 were excluded (no anti-reflux surgery performed (n = 96); surgeon retired (n = 5); paediatric surgeon (n = 3)). The number of operations performed by the 22 (16%) adult general surgeons who had performed laparoscopic anti-reflux surgery increased 4.6 times from 1991 to 1997 (474 open and 1218 laparoscopic operations). The median number of cases per surgeon was 30 (range: 5-300). In 1997 there were 208 (60%) total fundoplications (TF) and 135 (40%) partial fundoplications (PF) performed. Variations in the technique of TF included the Nissen-DeMeester (10 surgeons), the Nissen-Rosetti (nine surgeons), division of short gastric vessels (10 surgeons), and routine cruroplasty (14 surgeons). A PF had never been performed by six surgeons, was preferred by six surgeons, and four other surgeons were performing it more often. Variations in the technique of PF included posterior (12 surgeons) and anterior (four surgeons) forms.

CONCLUSION

There is significant variation in the technique of laparoscopic anti-reflux surgery in New Zealand. A TF is preferred by 16 surgeons, but there appears to be a trend towards PF among the more experienced surgeons.

Surgical treatment for recurrent gastro-oesophageal reflux disease after failed antireflux surgery

BACKGROUND

Recurrent or persistent symptoms occur in 10-15 per cent of patients after antireflux surgery. Failure of surgery is not uniform in its presentation. The cause of failure is not easily detected and even harder to treat. Different approaches have been proposed and few reports are available on the objective and subjective outcome of reoperation.

METHODS

This study focuses on 30 patients (16 men and 14 women; age range 20-69 years) with recurrent symptomatic gastro-oesophageal reflux disease (GORD) resistant to medical treatment. In all patients reoperation was by the Belsey Mark IV antireflux operation. A clinical history, endoscopy and oesophageal manometry were obtained in all patients, and 24-h pH monitoring was performed in 27 of 30 before and in most patients after the Belsey procedure.

RESULTS

Symptomatic improvement was reported in 24 of 30 patients. Oesophagitis (present before operation in 19 patients) was cured or remained absent in 24 of 30 patients, stabilized in one, improved in four and deteriorated in one. Relief of symptoms combined with absence of oesophagitis was obtained in 21 of 30 patients, with concomitant normalization of the 24-h pH profile in 11 of 22 patients. The median basal lower oesophageal sphincter (LOS) pressure increased significantly from 6. 9 to 9.0 mmHg (P < 0.01). Redo surgery had no effect on oesophageal body motility.

CONCLUSION

Reoperation performed for documented recurrent GORD had a good and lasting effect on symptoms, on oesophagitis (both in 24 of 30 patients) and on the combination of both (21 of 30). In these patients reoperation increased basal LOS pressure and decreased reflux time. Overall, the results approximate to those of primary operation.

Feasibility of 23-hour hospitalization after laparoscopic fundoplication

PURPOSE

In order to reduce the costs of laparoscopic fundoplication, a pilot program for outpatient surgery was instituted in 1995. The risks and benefits of reducing postoperative hospitalization to < or =23 hours were assessed.

PATIENTS AND METHODS

Patients in ASA grade I or II (N = 22) with refractory gastroesophageal reflux disease underwent laparoscopic fundoplication over a 21-month period in a hospital-affiliated outpatient facility. The results were compared with those of a similar group of 16 patients whose surgery was performed on an inpatient basis.

RESULTS

Seventeen patients (77%) were discharged within 23 hours of surgery. The maximum length of stay was 3 days. There were no deaths. Nineteen patients (86%) reported excellent results. The average facility cost declined from $7,169 for the inpatient group to $4,588 for patients on operated under the outpatient protocol. The decrease resulted from a reduction in the cost of room, operating suite, supplies, and anesthesia.

CONCLUSION

Laparoscopic fundoplication can be performed safely in a hospital-affiliated outpatient setting, resulting in a significant reduction in procedure costs.

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 patient's personal perception or faulty eating habits. The aim of this study was to investigate the impact of the patient's 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 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.

Open Nissen fundoplication and highly selective vagotomy as a treatment for gastro-oesophageal reflux disease

BACKGROUND

Open Nissen fundoplication has been the most common surgical treatment of gastro-oesophageal reflux disease (GORD). The present paper describes the symptomatic result, and quantifies the acid reduction achieved by open Nissen fundoplication combined with highly selective vagotomy (HSV) in a consecutive case series.

METHODS

A study of 106 patients undergoing open Nissen fundoplication and HSV for GORD was performed between 1988 and 1996. A history consistent with reflux was obtained and the diagnosis confirmed with ambulatory oesophageal pH studies and endoscopy. Postoperative pH studies were performed, and peri-operative and late complications were recorded. A standard questionnaire was sent out to patients postoperatively to assess the efficacy of surgery.

RESULTS

Pre-operative pH studies were performed on 104 (98%) patients, and on 97 (91.5%) following surgery. There was a highly significant improvement in all parameters of the pH study postoperatively. All symptoms, including bloating and dysphagia, improved significantly postoperatively, except flatulence, which was exacerbated. The majority of patients were very satisfied with their outcome, 82% rating the operation from 80 to 100% successful. Complications were rare and there was no mortality.

CONCLUSIONS

Open Nissen fundoplication and HSV is an effective method of treating GORD, producing an improvement in symptoms and in ambulatory pH studies.

Laparoscopic refundoplications after failed antireflux surgery

BACKGROUND

Open and laparoscopic antireflux procedures may require reoperation for failures of the initial procedure in about 3% to 6% of cases. The purpose of this study is to describe our operative experiences, postoperative results, and patients' view of outcome following laparoscopic refundoplication.

METHODS

Thirty patients (18 men, 12 women), mean age 56 years (range 37 to 77) underwent laparoscopic redo surgery. In 18 patients the initial surgery was done by the open technique, and 3 had surgery twice previously. Twelve patients had previous laparoscopic antireflux surgery. Indications for redo surgery were recurrent reflux (n = 17), dysphagia (n = 6), and the combination of both (n = 7).

RESULTS

Twenty-eight patients were completed laparoscopically, 21 with a floppy Nissen and 7 with a Toupet fundoplication. Two patients were converted to the open procedure because of intraoperative technical problems. In 5 cases there was an injury to the stomach wall, successfully managed laparoscopically. Postoperatively 1 patient had dysphagia and required pneumatic dilatation, another had gas bloat. There was a significant increase in lower esophageal sphincter pressure at 3 months (12.4+/-4.8 mm Hg; n = 30) and 1 year (12.3+/-4.5 mm Hg; n = 30). Twenty-four hour pH monitoring showed a decrease of the DeMeester Score at 3 months after surgery from 14.7+/-10.6 (n = 30) and 1 year after surgery from 12.1+/-8.7 (n = 30). Gastrointestinal quality of life index increased from 87 points preoperatively to 121 at 3 months and 123 at 1 year, which is comparable with a healthy population (123 points).

CONCLUSIONS

Laparoscopic refundoplication is a feasible and effective procedure with excellent postoperative results, independent of whether the primary procedure was done by the open or laparoscopic technique.

Postfundoplication complications. Prevention and management

Management of post-fundoplication problems begins by preventing complications from occurring. The prevention of complications after antireflux surgery can be divided into three important areas: (1) patient selection, (2) selection of the surgery, and (3) selection of the surgeon. After addressing prevention techniques, the author discusses the management of new postoperative symptoms such as Dysphagia, gas-bloat syndrome, and nausea and vomiting.

Interposition of a jejunal segment between esophagus and pylorus for treatment of multirecurrent gastroesophageal reflux

Here the authors report the clinical experience with placement of an isolated jejunal segment between the esophagus and pylorus for treatment of multirecurrent gastroesophageal reflux (GER) in a child. A 6-year-old neurologically normal girl experienced severe symptomatic GER after 3 previous well-constructed Nissen fundoplications that failed over a 4-year period. The gastric cardia was closed, and a 16-cm isolated segment of proximal jejunum was placed in an isoperistaltic direction between the distal esophagus and an incision through the pylorus, extending onto both the antrum and duodenum. A gastrostomy was used for 3 months. The patient recovered from the operation without complications and has been completely relieved of reflux symptoms during the 15 months postoperation. She has gained over 6.5 kg in weight and 3.2 cm in height during this period and has not experienced difficulty swallowing solid foods. Esophagogastric dissociation with placement of an isolated jejunal segment between the esophagus and pylorus may have a useful role in the surgical management of multirecurrent symptomatic GER as a "rescue procedure" with low risk compared with other options.

Laparoscopic fundoplication failures: patterns of failure and response to fundoplication revision

OBJECTIVE

To determine rates and mechanisms of failure in 857 consecutive patients undergoing laparoscopic fundoplication for gastroesophageal reflux disease or paraesophageal hernia (1991-1998), and compare this population with 100 consecutive patients undergoing fundoplication revision (laparoscopic and open) at the authors' institution during the same period.

SUMMARY BACKGROUND DATA

Gastroesophageal fundoplication performed through a laparotomy or thoracotomy has a failure rate of 9% to 30% and requires revision in most of the patients who have recurrent or new foregut symptoms. The frequency and patterns of failure of laparoscopic fundoplication have not been well studied.

METHODS

All patients undergoing fundoplication revision were included in this study. Symptom severity was scored before and after surgery by patients on a 4-point scale. Evaluation of patients included esophagogastroscopy, barium swallow, esophageal motility, 24-hour ambulatory pH, and gastric emptying studies. Statistical analysis was performed with multiple chi-square analyses, Fisher exact test, and analysis of variance.

RESULTS

Laparoscopic fundoplication was performed in 758 patients for gastroesophageal reflux disease and in 99 for paraesophageal hernia. Median follow-up was 2.5 years. Thirty-one patients (3.5%) have undergone revision for fundoplication failure. The mechanism of failure was transdiaphragmatic herniation of the fundoplication in 26 patients (84%). In 40 patients referred from other institutions, after laparoscopic fundoplication, only 10 (25%) had transdiaphragmatic migration (p < 0.01); a slipped or misplaced fundoplication occurred in 13 patients (32%), and a twisted fundoplication in 12 patients (30%). The failure mechanisms of open fundoplication (29 patients) followed patterns previously described. Fundoplication revision procedures were initiated laparoscopically in 65 patients, with six conversions (8%). The morbidity rate was 4% in laparoscopic procedures and 9% in open ones. There was one death, from aspiration and adult respiratory distress syndrome after open fundoplication. A year or more after revision operation, heartburn, chest pain, and dysphagia were rare or absent in 88%, 78%, and 91%, respectively, after laparoscopic revision, and were rare or absent in 91%, 83%, and 70%, respectively, after open revision, but 11 patients ultimately required additional operations for continued or recurrent symptoms, 3 after open revision (17%), and 8 after laparoscopic fundoplication (11%).

CONCLUSIONS

Laparoscopic fundoplication failure is infrequent in experienced hands; the rate may be further reduced by extensive esophageal mobilization, secure diaphragmatic closure, esophageal lengthening (applied selectively), and avoidance of events leading to increased intraabdominal pressure. When revision is required, laparoscopic access may be used successfully by the laparoscopically experienced esophageal surgeon.

Antireflux surgery followed by bipolar electrocoagulation in the treatment of Barrett's esophagus

BACKGROUND

Management of Barrett's esophagus requires reduction of gastric acid secretion and screening for the development of adenocarcinoma. However, the current therapeutic options are ineffective in reducing the Barrett's mucosa. The aim of this study was to evaluate the effectiveness of endoscopic thermal coagulation of Barrett's mucosa as an alternative therapeutic approach and the recurrence of the disease in the long term.

METHODS

Fourteen patients (11 men, 3 women; mean age 45.7 years) with Barrett's esophagus participated in the study. They underwent laparoscopic fundoplication and were symptom free with no defective fundoplication wraps before therapeutic endoscopy. Endoscopic thermocoagulation was performed with a flexible videoendoscope and a bipolar probe. Mucosal areas were treated once a month until the Barrett's mucosa disappeared. Endoscopy was performed 1 and 7 months after completion of the treatments and once a year thereafter.

RESULTS

The mean follow-up period was 21.6 months (range 18 to 30 months). The mean length of Barrett's esophagus was 4.8 cm. Successful ablation of the columnar epithelium was achieved in 3.7 sessions, as defined by demonstration of normal squamous epithelium at histologic examination of biopsy samples collected after completion of the treatments and at follow-up evaluations. Three patients experienced short-term (10 days) odynophagia or dysphagia. All patients were symptom free with no evidence of Barrett's esophagus at the end of the study.

CONCLUSIONS

Bipolar electrocoagulation after antireflux operations is effective in promoting regression of Barrett's esophagus and has few complications. Endoscopic thermal coagulation might reduce risk for adenocarcinoma among these patients.

Anatomic fundoplication failure after laparoscopic antireflux surgery

OBJECTIVE

Anatomic fundoplication failure occurs after antireflux surgery and may be more common in the learning curve of laparoscopic antireflux surgery (LARS). The authors' aims were to assess the incidence, presentation, precipitating factors, and management of anatomic fundoplication failures after LARS.

SUMMARY BACKGROUND DATA

The advent of LARS has increased the frequency with which antireflux surgery is performed for the treatment of gastroesophageal reflux disease. Postoperative symptoms frequently occur and may result from physiologic abnormalities or anatomic failure of the fundoplication (e.g., displacement or disruption). Few data exist on the potential causes or best treatment of anatomic fundoplication failures.

METHOD

LARS was performed in 290 patients by one of the authors over a 6-year period. In the first 53 patients (group 1), the short gastric vessels were divided on a selective basis and the diaphragmatic crura were closed only when large hiatal hernias were present. In the subsequent 237 patients (group 2), the crura were always approximated posterior to the short gastric vessels and full fundic mobilization was performed. Clinical postoperative evaluation was performed on a regular basis, with detailed tests of anatomy and physiology when untoward symptoms developed. Postoperative foregut symptoms were reported by 26% of the patients, of whom 73% were found to have an intact fundoplication. In 7% of the entire group, anatomic failure of the fundoplication was demonstrated, with the majority exhibiting intrathoracic migration of the wrap with or without disruption of the fundoplication. New-onset postoperative epigastric or substernal chest pain frequently heralded fundoplication failure. Factors correlated with the development of anatomic fundoplication failure included presence in group 1, early postoperative vomiting, other diaphragm "stressors," and large hiatal hernias. Repeat operation has been performed in 8 of the 20 patients (40%), with 5 patients successfully treated using laparoscopic techniques.

CONCLUSIONS

Anatomic fundoplication failure occurred in 7% of patients undergoing LARS, with the majority occurring in patients who underwent surgery during the learning curve. Anatomic failure is associated with technical shortcomings, large hiatal hernias, and early postoperative vomiting. Full esophageal mobilization and meticulous closure of the diaphragmatic crura posterior to the esophagus should minimize anatomic functional failure after LARS.

Laparoscopic reoperation following failed antireflux surgery

BACKGROUND

The aim was to determine the feasibility of laparoscopic revision surgery following previous open and laparoscopic antireflux operations.

METHODS

The outcome was determined for 27 patients (14 men, 13 women) who had undergone attempted laparoscopic revision between 3 months and 25 years after a previous antireflux operation. Median follow-up was 12 (range 3-48) months.

RESULTS

Thirteen patients had previously had an open antireflux procedure (Nissen fundoplication, seven; transthoracic anatomical repair, five; Belsey procedure, one) and 14 a laparoscopic procedure (Nissen, 12; anterior partial fundoplication, two). The indications for revision were: recurrent reflux, 15; paraoesophageal hiatus hernia, six; troublesome dysphagia, six. Fifteen procedures comprised construction of a new Nissen fundoplication, six conversion from a Nissen to a partial wrap, three repair of a paraoesophageal hernia and three widening of the oesophageal hiatus. Revision was successfully completed laparoscopically in 12 patients following a previous laparoscopic procedure and in nine following a previous open operation. Median operating time was 105 min after previous open surgery and 80 min after laparoscopic surgery. No perioperative complications occurred in either group and a good outcome was achieved in 25 of the 27 patients.

CONCLUSION

Laparoscopic reoperative antireflux surgery is feasible. Reoperation is likely to be more difficult following failure of an open procedure than a laparoscopic one.

Management of intrathoracic stomach with polypropylene mesh prosthesis reinforced transabdominal hiatus hernia repair

BACKGROUND

Posterior cruroplasty repair of a large paraesophageal hiatus hernia has a higher than desirable rate of recurrence attributable to the inexorable cyclic negative intrathoracic pressure of respiration and positive intraabdominal pressure produced by straining, physical exertion, and coughing. To reduce the risk of recurrence after repair of a large hiatus hernia and intrathoracic stomach, we have used posterior cruroplasty reinforced with an onlay polypropylene mesh prosthesis. This paper reviews the feasibility of this technique.

STUDY DESIGN

We did a retrospective review of 44 patients with large hiatus hernia and intrathoracic stomach who had posterior cruroplasty and onlay of polypropylene mesh prosthesis applied to the crura and adjacent diaphragm to repair the hiatal defect.

RESULTS

Preoperative symptoms (mean duration, 26 months) included pain (33 patients), vomiting (21), dysphagia (19) and anemia (8). The typical patient (28 men and 16 women, mean age, 60) had two-thirds or more of the stomach above the diaphragm. Organoaxial gastric volvulus and herniated large or small bowel were present in 10 and 9 patients, respectively. A gastrostomy was performed for temporary drainage in 38 patients in addition to the hernia repair; 11 patients underwent a concomitant Nissen fundoplication. Postoperative complications included pleural effusion (four patients), atrial dysrhythmia (three patients), and superficial wound infection (two patients). Mean followup for 43 patients was 52 months. There have been no clinical recurrences.

CONCLUSIONS

Mesh prosthesis reinforced hiatus hernia repair is effective, appears to have a low clinical recurrence rate, and should be an option in the treatment of a large hiatus hernia with intrathoracic stomach.

Comparison of outcomes of open versus laparoscopic Nissen fundoplication performed in a single practice

BACKGROUND

We reviewed Nissen fundoplications performed in a single practice from January 1989 to March 1997, encompassing our transition from open to laparoscopic procedures. Because all operations were done by two surgeons in the same two hospitals, the study is well controlled for comparisons.

METHODS

Records of 271 consecutive patients were reviewed.

RESULTS

From 1989 to 1992 all patients underwent open fundoplication (n = 78). Thereafter, with increasing frequency, laparoscopic fundoplication was performed. The laparoscopic group was slightly younger (48 +/- 14 years) than the open group (54 +/- 13 years), but gender distribution and body mass index (BMI) did not differ. Mean operating time for laparoscopic cases was 163 +/- 58 minutes compared with 148 +/- 59 minutes for open cases (NS). Intraoperative complication rate was 8% for both groups. Length of hospitalization was shorter for patients undergoing laparoscopic surgery (2.4 days versus 7.2 for open procedures, P <0.05). In follow-up, 82% of the open Nissen group were asymptomatic compared with 84% of the laparoscopic Nissen group. The same proportion of patients required reoperation for dysphagia (3% for each group). Of patients who had the open procedure, 21% had wound complications. None of those treated laparoscopically had long-term morbidity from trocar insertion sites.

CONCLUSION

Equal effectiveness in treating reflux combined with shorter hospitalization and absence of wound complications makes the laparoscopic approach the preferred method for performing fundoplication.

Esophagectomy for unsuccessful antireflux operations

BACKGROUND

Primary antireflux surgery provides excellent symptom relief in most patients. Unfortunately, the results of redo surgery are less predictable. In these patients, esophageal injury from long-standing reflux of gastric contents and operative trauma from previous failed antireflux procedures results in progressive deterioration in esophageal propulsion, poor clearance of reflux episodes, mucosal damage, and, in some cases, stricture formation. For the past 16 years, we have selectively used esophageal resection and replacement instead of another reoperation in these challenging patients.

METHODS

Seventeen patients with end-stage esophageal body dysfunction and one or more previously unsuccessful antireflux procedures underwent esophagectomy and reconstruction by colon interposition in 15 patients and jejunum interposition in 2 patients. The indications for esophagectomy rather than a redo antireflux procedure were a global loss of effective esophageal motility in 13 and a nondilatable stricture in four. Their outcome was compared with that of 32 patients with adequate motility and 18 with a similar global loss of motility who had a redo antireflux procedure. Perioperative complications after esophagectomy were recorded, and long-term outcome was assessed by means of a standardized questionnaire at a median of 7 years after the operation.

RESULTS

Patients with profound esophageal body dysfunction who underwent esophageal resection had outcomes similar to those with normal motility who underwent a redo antireflux procedure. Those with profound esophageal motility dysfunction who underwent a redo antireflux procedure had a worse outcome than those who underwent resection. Esophageal resection and replacement was performed without mortality or graft failure. All patients who underwent resection stated that their preoperative symptoms were relieved completely (n = 6) or improved (n = 10). Thirteen patients (81%) were able to eat three meals a day, and 12 patients (75%) enjoyed an unrestricted diet. Two thirds of the patients were at or above their ideal body weight, and 88% were fully satisfied with the outcome of the procedure.

CONCLUSION

Patients with end-stage esophageal body dysfunction who have had a previous unsuccessful antireflux procedure can be treated by esophageal resection with a high expectation of success.

Laparoscopic antireflux surgery and the thoracic surgeon: what now?

OBJECTIVE

Minimal invasive antireflux surgery is now a well accepted technique gaining a wide spread popularity. Simultaneously there is a growing tendency to fit all surgical candidates into one single type of operation, i.e. laparoscopic Nissen antireflux operation. This study evaluates the impact of this new technology on the strategy and practice of a major referral centre for antireflux surgery.

METHODS

An analysis was made of indications for the different types of antireflux techniques performed between July, 1993 and 1995. If on Barium swallow the gastro-oesophageal (GO) junction proved to be reducible, a laparoscopic approach was proposed, if not, an open transthoracic access was preferred.

RESULTS

One hundred and fifteen patients were operated. Fifty five patients underwent a minimal invasive approach: 49 Nissen (are the total fundoplication) and 3 Lind (are the partial fundoplication) operations through laparoscopy, 3 Belsey Mark IV through video assisted thoracic surgery (VATS). Sixty patients were treated by open surgery for following reasons: conversion to open surgery in 2 cases, redo surgery in 15 cases, previous other major abdominal surgery in 12, irreducible GO junction in 5, paraoesophageal or mixed type hernia in 12, Barrett and or oesophagitis IV in 4, combined antireflux surgery and feeding gastrostomy in 5, abdominal partial fundoplication by principle in 1, associated motility disorder in 1, combined reflux and gastric ulcer disease in 2, and severe emphysema in 1. In the laparoscopic series reflux control at 1 year post surgery as measured by 24 h pH study in 28 patients was obtained in 89.5%. One patient required a reoperation for symptomatic recurrence.

CONCLUSIONS

(1) Laparoscopic antireflux surgery is a feasible and well accepted technique; (2) careful study of each individual patient is of paramount importance to choose the correct type of operation and access as well. Therefore, fitting every patient into a single type of operation, i.e. laparoscopic Nissen, should be avoided; (3) thoracic surgeons with a major interest in GO reflux disease should familiarize themselves with laparoscopic antireflux procedures.

Management of the failed antireflux operation

A further operation is required in a small proportion of patients who have had prior antireflux surgery. This has a surprisingly good chance for success in appropriately evaluated patients. The surgeon must make very specific decisions regarding the surgical approach. The use of laparoscopy for redo surgery is being defined.

The surgical management of Barrett's esophagus

Barrett's esophagus is an increasing health concern in most Western countries. The diagnosis is usually made during investigation of patients with symptoms of gastroesophageal reflux disease. The appropriate antireflux procedure, performed in properly selected patients, provides long-term symptomatic relief in 80% to 90% of patients. The effect of reliable and complete control of gastroesophageal reflux on the natural history of Barrett's metaplasia once it has developed and on its prevention in symptomatic patients who have not yet developed Barrett's changes is one of the most important areas of study over the next decade.

Laparoscopic redo Nissen fundoplication

Nine patients underwent redo laparoscopic Nissen fundoplication because of failed primary laparoscopic antireflux procedure. Symptoms prior to reoperation included heartburn (n = 5), dysphagia (n = 2), dysphagia and heartburn (n = 1), and early satiety and epigastric pain (n = 1). Endoscopic and radiologic findings prior to reoperation included esophagitis (n = 6), reflux (n = 6), stenosis (n = 2), and hiatal hernia (n = 1). Findings at reoperation included fundoplication positioned on the stomach (n = 5); a disrupted cruroplasty (n = 1); gastric volvulus (n = 1); and an excessively tight wrap (n = 1) or cruroplasty (n = 1). Reconstruction of the fundoplication was performed according to accepted principles for this procedure. All patients were discharged within 2 days after the redo procedure. Follow-up time is 4-14 months. Preoperative symptoms were relieved in all patients and all antireflux medication have been discontinued. Routine postoperative esophagram and endoscopy demonstrated intact repair and without gastroesophageal reflux or stenosis. Reoperative laparoscopic Nissen fundoplication is feasible and effective.

Long-term results after reoperation for failed antireflux procedures

From January 1960 to June 1995, 185 patients underwent reoperation without esophageal resection for symptoms of recurrent gastroesophageal reflux disease. There were 102 men and 83 women. Median age was 58 years (range 20 to 84 years). A single previous antireflux operation had been performed in 147 patients, two in 33, and three in 5. The median interval between the reoperation and the previous operation was 36 months (range 1 to 291 months). Indications for reoperation were symptoms in 184 patients and a large paraesophageal hernia in one patients. The surgical approach was by means of a thoracotomy in 133 patients (71.9%), laparotomy in 27 (14.6%), and a thoracoabdominal incision in 25 (13.5%). A Nissen fundoplication was performed in 107 patients (57.8%), Belsey fundoplication in 47 (25.4%), truncal vagotomy and antrectomy with Roux-en-Y reconstruction in 17 (9.2%), anatomic hernia repair in 12 (6.5%), and Hill gastropexy in 2 (1.1%). A Collis gastroplasty was added to the fundoplication in 116 patients (62.7%), and a pyloroplasty was performed in 17 (9.2%). There was one operative death (0.5%). Complications occurred in 47 patients (25.4%). Median postoperative hospitalization was 9 days (range 5 to 58 days). Follow-up was complete in 156 patients (84.3%) and ranged from 3 to 283 months (median 44 months). Improvement occurred in 137 patients (87.8%). Functional results were classified as excellent in 65 patients (41.6%), good in 29 (18.6%), fair in 43 (27.6%), and poor in 19 (12.2%). No single operative approach or procedure proved to be functionally superior. We conclude that reoperation with esophageal preservation after a failed antireflux procedure will result in significant functional benefit and can be performed with low mortality and acceptable morbidity. The type of repair should be tailored to the individual patient.
