Outcome of laparoscopic redo fundoplication

Outcomes of Laparoscopic Redo Fundoplication in Patients With Failed Antireflux Surgery: A Systematic Review and Meta-analysis

OBJECTIVE

The aim of this meta-analysis was to summarize the current available evidence regarding the surgical outcomes of laparoscopic redo fundoplication (LRF).

SUMMARY OF BACKGROUND DATA

Although antireflux surgery is highly effective, a minority of patients will require a LRF due to recurrent symptoms, mechanical failure, or intolerable side-effects of the primary repair.

METHODS

A systematic electronic search on LRF was conducted in the Medline database and Cochrane Central Register of Controlled Trials. Conversion and postoperative morbidity were used as primary endpoints to determine feasibility and safety. Symptom improvement, QoL improvement, and recurrence rates were used as secondary endpoints to assess efficacy. Heterogeneity across studies was tested with the Chi-square and the proportion of total variation attributable to heterogeneity was estimated by the inconsistency (I2) statistic. A random-effect model was used to generate a pooled proportion with 95% confidence interval (CI) across all studies.

RESULTS

A total of 30 studies and 2,095 LRF were included. The mean age at reoperation was 53.3 years. The weighted pooled proportion of conversion was 6.02% (95% CI, 4.16%-8.91%) and the meta-analytic prevalence of major morbidity was 4.98% (95% CI, 3.31%-6.95%). The mean follow-up period was 25 (6-58) months. The weighted pooled proportion of symptom and QoL improvement was 78.50% (95% CI, 74.71%-82.03%) and 80.65% (95% CI, 75.80%-85.08%), respectively. The meta-analytic prevalence estimate of recurrence across the studies was 10.71% (95% CI, 7.74%-14.10%).

CONCLUSIONS

LRF is a feasible and safe procedure that provides symptom relief and improved QoL to the vast majority of patients. Although heterogeneously assessed, recurrence rates seem to be low. LRF should be considered a valuable treatment modality for patients with failed antireflux surgery.

Redo Surgery after Failure of Antireflux Surgery

Surgery for refractory gastroesophageal reflux disease (GERD) has a satisfactory outcome for most patients; however, sometimes redo surgery is required. The Outcome and morbidity of a redo are suggested to be less successful than those of primary surgery. The aim of this study was to describe our experience, long-term results, and complications in redo surgery. From 2000 to 2016, 765 patients were operated on for GERD at our hospital. A retrospective analysis of 56 patients (7.3%) who underwent redo surgery was conducted. Large symptomatic recurrent hiatal hernia (50%) and dysphagia (28.6%) were the most frequent indications for redo. An open approach was chosen in 64.5 per cent of patients. Intraoperative and postoperative complication rates were 18 per cent and 14.3 per cent, respectively. Mortality rate was 1.8 per cent. Symptomatic outcome was successful in 71.3 per cent. Patients reoperated because of dysphagia and large recurrent hiatal hernia had a significantly higher failure rate (32.3% and 31.2%, respectively; P = 0.001). Complication rate was significantly lower in the laparoscopic group (0% vs 22.2%; P = 0.04). There were no statistical differences between expert and nonexpert surgeons. Laparoscopic approach has increased to 83.3 per cent in the last five years. Symptomatic outcome after redo surgery was less satisfactory than that after primary surgery. Complications were lower if a minimally invasive surgical approach was used.

Evaluation of conventional laparoscopic versus robot-assisted laparoscopic redo hiatal hernia and antireflux surgery: a cohort study

Surgery for refractory gastroesophageal reflux disease (GERD) and hiatal hernia leads to recurrence or persisting dysphagia in a minority of patients. Redo antireflux surgery in GERD and hiatal hernia is known for higher morbidity and mortality. This study aims to evaluate conventional versus robot-assisted laparoscopic redo antireflux surgery, with the objective to detect possible advantages for the robot-assisted approach. A single institute cohort of 75 patients who underwent either conventional laparoscopic or robot-assisted laparoscopic redo surgery for recurrent GERD or severe dysphagia between 2008 and 2013 were included in the study. Baseline characteristics, symptoms, medical history, procedural data, hospital stay, complications and outcome were prospectively gathered. The main indications for redo surgery were dysphagia, pyrosis or a combination of both in combination with a proven anatomic abnormality. The mean time to redo surgery was 1.9 and 2.0 years after primary surgery for the conventional and robot-assisted groups, respectively. The number of conversions was lower in the robot-assisted group compared to conventional laparoscopy (1/45 vs. 5/30, p = 0.035) despite a higher proportion of patients with previous surgery by laparotomy (9/45 vs. 1/30, p = 0.038). Median hospital stay was reduced by 1 day (3 vs. 4, p = 0.042). There were no differences in mortality, complications or outcome. Robotic support, when available, can be regarded beneficial in redo surgery for GERD and hiatal hernia. Results of this observational study suggest technical feasibility for minimal-invasive robot-assisted redo surgery after open primary antireflux surgery, a reduced number of conversions and shorter hospital stay.

Use of acid-suppressive therapy before anti-reflux surgery in 2922 patients: a nationwide register-based study in Denmark

BACKGROUND

Guidelines recommend that patients with gastro-oesophageal reflux disease are adequately treated with acid-suppressive therapy before undergoing anti-reflux surgery. Little is known of the use of acid-suppressive drugs before anti-reflux surgery.

AIM

To determine the use of proton pump inhibitors and H2 -receptor antagonists in the year before anti-reflux surgery.

METHODS

A nationwide retrospective study of all patients aged ≥18 undergoing first-time anti-reflux surgery in Denmark during 2000-2012 using data from three different sources: the Danish National Register of Patients, the Danish National Prescription Register, and the Danish Person Register.

RESULTS

The study population thus included 2922 patients (median age: 48 years, 55.7% male). The annual proportion of patients redeeming ≥180 DDD of acid-suppressive therapy increased from 17.0% 5 years before anti-reflux surgery to 64.9% 1 year before. The probability for inadequate dosing 1 year before surgery (<180 DDD) was significantly increased for younger patients, patients operated in the period 2000-2003, patients who had not undergone pre-surgical manometry, pH- or impedance monitoring, and patients who had not redeemed prescriptions on NSAID or anti-platelet drugs.

CONCLUSION

Compliance with medical therapy should be evaluated thoroughly before planning anti-reflux surgery, as a high proportion of patients receive inadequate dosing of acid-suppressive therapy prior to the operation.

Reoperative antireflux surgery

Patient satisfaction with primary antireflux surgery is high, but a small percentage of patients experience recurrent reflux and dysphagia, requiring reoperation. The major anatomic causes of failed fundoplication are slipped fundoplication, failure to identify a short esophagus, and problems with the wrap. Minimally invasive surgery has become more common for these procedures. Options for surgery include redo fundoplication with hiatal hernia repair if needed, conversion to Roux-en-Y anatomy, or, as a last resort, esophagectomy. Conversion to Roux-en-Y anatomy has a high rate of success, making this approach an important option in the properly selected patient.

Does BMI predict recurrence or complications after reoperative reflux surgery? Review of a single center's experience and a comparison of outcomes

INTRODUCTION

Obese patients who fail primary surgical management of gastroesophageal reflux present a significant challenge. We reviewed our outcomes with reoperative reflux surgery in obese (body mass index (BMI) >30) and nonobese patients to identify predictors of failure and complications and evaluate whether reoperative fundoplication is the ideal solution for obese patients.

METHODS

We conducted a retrospective review of consecutive patients undergoing reoperation for failed anti-reflux surgery between 1994 and 2013. Medical record review identified preoperative, intraoperative, and postoperative characteristics. Short- and long-term outcomes for obese and nonobese patients were compared using descriptive statistics and logistic regression.

RESULTS

One hundred and nine interventions were identified in 95 patients. Clinical characteristics were similar between obese and nonobese patients. Eighty-eight (83.8%) patients underwent laparoscopic repair, 87 (79.8%) of whom had a Nissen fundoplication. Obese patients were more likely to fail via a slipped wrap (64.7 vs. 40.0%; p = 0.02). No differences were seen in short- or long-term symptomatic relief or major complications. In bivariate analysis, short-term outcomes were predicted by preoperative albumin <3.5 mg/dL (odds ratio (OR), 0.27 (confidence interval (CI), 0.08-0.96); p = 0.04) and laparoscopic conversion (OR, 0.19 (CI, 0.04-1.03); p = 0.05). Laparoscopic conversion was associated with major complications (OR, 7.33 (CI, 1.33-40.55); p = 0.02). BMI was a significant predictor for long-term outcome (p = 0.03) as a continuous variable in sensitivity analyses.

CONCLUSIONS

Obese patients with recurrence after failed anti-reflux operation may be safely treated with a repeat operation. Our data indicate no difference in outcomes for patients with BMI >30, underscoring the importance of preoperative discussion as to the best approach: reoperative fundoplication or a gastric bypass.

Reoperation rates after laparoscopic fundoplication

INTRODUCTION

Current literature on redo antireflux surgery has limitations due to small sample size or single center experiences. This study aims to evaluate the reoperation rate of laparoscopic fundoplication in a large population database.

METHODS

A longitudinal version of the California Office of Statewide Health Planning and Development database from 1995 to 2010 was used. Inclusion criteria were patients who received a laparoscopic fundoplication for uncomplicated gastroesophageal reflux disease (GERD) or hiatal hernia. Patients were excluded if they had complications of GERD, esophageal or gastric cancer, prior esophageal or gastric surgery, vagotomy, esophageal dysmotility, and diaphragmatic hernia with gangrene or obstruction. The outcome was reoperation, specified as another fundoplication or reversal. Analysis was carried out via a Kaplan-Meier plot, hazard curve, and multivariate analysis adjusting for age, race, gender, comorbidities, insurance status, hospital teaching status, and year of procedure.

RESULTS

13,050 patients were included in the study. The 5 and 10-year cumulative reoperation rates were 5.2 % (95 % CI 4.8-5.7%) and 6.9 % (95 % CI 6.1-7.9%), respectively. Of these reoperations, 30 % were performed at a different hospital from that of the initial fundoplication. Reoperation rate was highest at 1 year post-operatively (1.7 % per year), and steadily declined until 4 years post-operatively, after which it remained at approximately 0.5 % per year. Multivariate analysis demonstrated significantly higher rates of reoperation among younger patients (HR = 3.56 for <30yo; HR = 1.89 for 30-50yo; HR = 1.65 for 50-65yo) and female patients (HR = 1.35).

CONCLUSIONS

Nearly one third of reoperations after failed laparoscopic fundoplication occur at a hospital different from the initial operation, which raises concern that existing literature does not reflect the true reoperation rate. The reoperation rate is highest in the first year postoperatively. The reasons for the higher rate of reoperation in females and younger patients remain unclear and warrant further study.

EAES recommendations for the management of gastroesophageal reflux disease

BACKGROUND

Gastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett's esophagus, and enteroesophageal and duodenogastroesophageal reflux.

METHODS

The European Association of Endoscopic Surgery (EAES) has tasked a group of experts, based on their clinical and scientific expertise in the field of GERD, to establish current guidelines in a consensus development conference. The expert panel was constituted in May 2012 and met in September 2012 and January 2013, followed by a Delphi process. Critical appraisal of the literature was accomplished. All articles were reviewed and classified according to the hierarchy of level of evidence and summarized in statements and recommendations, which were presented to the scientific community during the EAES yearly conference in a plenary session in Vienna 2013. A second Delphi process followed discussion in the plenary session.

RESULTS

Recommendations for pathophysiologic and epidemiologic considerations, symptom evaluation, diagnostic workup, medical therapy, and surgical therapy are presented. Diagnostic evaluation and adequate selection of patients are the most important features for success of the current management of GERD. Laparoscopic fundoplication is the most important therapeutic technique for the success of surgical therapy of GERD.

CONCLUSIONS

Since the background of GERD is multifactorial, the management of this disease requires a complex approach in diagnostic workup as well as for medical and surgical treatment. Laparoscopic fundoplication in well-selected patients is a successful therapeutic option.

Evaluation of gastrectomy in patients with delayed gastric emptying after antireflux surgery or large hiatal hernia repair

BACKGROUND

Revision antireflux surgery and large hiatal hernia repair require extensive dissection at the gastroesophageal junction. This may lead to troublesome symptoms due to delayed gastric emptying, eventually requiring gastrectomy. The aim of this study was to evaluate the outcome of gastrectomy for severely delayed gastric emptying after large hiatal hernia repair or redo antireflux surgery.

METHODS

Eleven patients were treated between 1995 and 2010 and entered in the study. Preoperative and operative data were retrospectively collected. Standardized questionnaires were sent to all of the patients to evaluate symptomatic outcome.

RESULTS

The primary intervention was Nissen fundoplication in nine patients, Toupet fundoplication in one, and cruroplasty in another. The repairs were for refractory gastroesophageal reflux disease in five patients and a symptomatic large hiatal hernia in six. Subsequent gastrectomy was partial in four patients, subtotal in six, and total in one. There was one minor postoperative complication. After a mean (±SD) duration of 102 ± 59 months, nine patients were available for symptomatic follow-up. Eight patients experienced daily symptoms related to dumping. Daily symptoms indicative of delayed gastric emptying were present in seven patients at follow-up. Mean general quality of life was increased from 3.8 ± 2.2 before gastrectomy to 5.4 ± 1.8 at follow-up. Eight patients reported gastrectomy as worthwhile.

CONCLUSION

Gastrectomy after previous antireflux surgery or large hiatal hernia repair is safe with the potential to improve quality of life. Although upper gastrointestinal symptoms tend to persist, gastrectomy can be considered a reasonable, last-resort surgical option for alleviating upper gastrointestinal symptoms after this kind of surgery.

Laparoscopic revision of failed antireflux surgery: a systematic review

BACKGROUND

Laparoscopic antireflux surgery is an accepted treatment for persistent gastroesophageal reflux but about 4% of patients will eventually require revision surgery.

METHODS

We searched The Cochrane Collaboration, Medline, and EMBASE databases, augmented by Google Scholar and PubMed related articles from January 1, 1990, to November 22, 2010. Twenty studies met the inclusion criteria, reporting on 930 surgeries.

RESULTS

The mean surgical duration was 166 minutes and conversion to open revision fundoplication was required in 7% of cases. Complications were reported in 14% of cases and the mean length of stay varied between 1.2 and 6 days. A good to excellent result was reported for 84% of surgeries and 5% of patients required a further revisional procedure.

CONCLUSIONS

Laparoscopic revision antireflux surgery appears to be feasible and safe, but subject to somewhat greater risk of conversion, higher morbidity, longer hospital stay, and poorer outcomes than primary laparoscopic fundoplication.

Nissen fundoplication after failure of endoluminal fundoplication: short-term results

BACKGROUND

Endoluminal fundoplication (ELF) with EsophyX is a new attractive investigational procedure for the control of gastroesophageal reflux disease (GERD). The aim of this work is to evaluate the short-term results of Nissen fundoplication (NF) after failure of ELF.

METHOD

During the period April 2007-January 2010, nine patients previously treated with ELF for GERD were submitted to laparoscopic NF for persistent reflux.

RESULTS

All patients were symptomatic for GERD, had a pathological esophageal acid exposure at multichannel intraluminal impedance (MII pH/24 h), and all of them were on proton pump inhibitor. Mean duration of the NF was 85 min (range, 56-104). There were no intraoperative complications. One patient had a postoperative mild peritoneal bleeding treated conservatively. After a mean follow-up of 24.9 months (4-34), all patients are asymptomatic for reflux. Two patients have a mild or moderate dysphagia at follow-up. Five patients underwent MII pH/24 h 1 year after surgery. Mean total reflux time was 0.3%, and acid reflux percent time was 0.

CONCLUSIONS

Patients with persistent symptomatic reflux after a failing ELF can still undergo NF with good results; the endoluminal procedure does not seem to modify the results of the laparoscopic procedure, although an increased incidence of dysphagia pos-NF may be observed.

Meta-analysis of randomized clinical trials comparing open and laparoscopic anti-reflux surgery

OBJECTIVES

The aim of this study was to conduct a meta-analysis of randomized evidence to determine the relative merits of laparoscopic anti-reflux surgery (LARS) and open anti-reflux surgery (OARS) for proven gastro-esophageal reflux disease (GERD).

METHODS

A search of the Medline, Embase, Science Citation Index, Current Contents, and PubMed databases identified all randomized clinical trials that compared LARS and OARS and that were published in the English language between 1990 and 2007. A meta-analysis was carried out in accordance with the QUOROM (Quality of Reporting of Meta-Analyses) statement. The six outcome variables analyzed were operating time, hospital stay, return to normal activity, perioperative complications, treatment failure, and requirement for further surgery. Random-effects meta-analyses were carried out using odds ratios (ORs) and weighted mean differences (WMDs).

RESULTS

Twelve trials were considered suitable for the meta-analysis. A total of 503 patients underwent OARS and 533 had LARS. For three of the six outcomes, the summary point estimates favored LARS over OARS. There was a significant reduction of 2.68 days in the duration of hospital stay for the LARS group compared with that for the OARS group (WMD: -2.68, 95% confidence interval (CI): -3.54 to -1.81; P<0.0001), a significant reduction of 7.75 days in return to normal activity for the LARS group compared with that for the OARS group (WMD: -7.75, 95% CI: -14.37 to -1.14; P=0.0216), and finally, there was a statistically significant reduction of 65% in the relative odds of complication rates for the LARS group compared with that for the OARS group (OR: 0.35, 95% CI: 0.16-0.75; P=0.0072). The duration of operating time was significantly longer (39.02 min) in the LARS group (WMD: 39.02, 95% CI: 17.99-60.05; P=0.0003). Treatment failure rates were comparable between the two groups (OR: 1.39, 95% CI: 0.71-2.72; P=0.3423). Despite this, the requirement for further surgery was significantly higher in the LARS group (OR: 1.79, 95% CI: 1.00-3.22; P=0.05).

CONCLUSIONS

On the basis of this meta-analysis, the authors conclude that LARS is an effective and safe alternative to OARS for the treatment of proven GERD. LARS enables a faster convalescence and return to productive activity, with a reduced risk of complications and a similar treatment outcome, than an open approach. However, there is a significantly higher rate of re-operation (79%) in the LARS group.

Management of complications after laparoscopic Nissen's fundoplication: a surgeon's perspective

Introduction

Gastro-oesophageal reflux disease (GORD) is a common problem in the Western countries, and the interest in the minimal access surgical approaches to treat GORD is increasing. In this study, we would like to discuss the presentations and management of complications we encountered after Laparoscopic Nissen's fundoplication in our District General NHS Hospital. The aim is to recognise these complications at the earliest stage for effective management to minimise the morbidity and mortality.

Methods

301 patients underwent laparoscopic treatment for GORD by a single consultant surgeon in our NHS Trust from September 1999. The data was prospectively collected and entered into a database. The data was retrospectively analysed for presentations for complications and their management.

Results

Surgery was completed laparoscopically in all patients, except in five, where the operation was technically difficult due to pre-existing conditions. The complications we encountered during surgery and follow-up period were major intra-operative bleeding (n = 1, 0.33%), severe post-operative nausea and vomiting (n = 1, 0.33%), wound infection (n = 3, 1%), port-site herniation (n = 1, 0.33%), wrap-migration (n = 2, 0.66%), wrap-ischaemia (n = 1, 0.33%), recurrent regurgitation (n = 4, 1.32%), recurrent heartburn (n = 29, 9.63%), tension pneumothorax (n = 2, 0.66%), surgical emphysema (n = 8, 2.66%), and port-site pain (n = 4, 1.33%).

Conclusion

Minimal access approach to treat GORD has presented with some specific and unique complications. It is important to recognise these complications at the earliest possible stage as some of these patients may present in an acute setting requiring emergency surgery. All members of the department, and not just the members of the specialised team, should be aware about these complications to minimise the morbidity and mortality.

Surgical reintervention after failed antireflux surgery: a systematic review of the literature

BACKGROUND

Outcome and morbidity of redo antireflux surgery are suggested to be less satisfactory than those of primary surgery. Studies reporting on redo surgery, however, are usually much smaller than those of primary surgery. The aim of this study was to summarize the currently available literature on redo antireflux surgery.

MATERIAL AND METHODS

A structured literature search was performed in the electronic databases of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials.

RESULTS

A total of 81 studies met the inclusion criteria. The study design was prospective in 29, retrospective in 15, and not reported in 37 studies. In these studies, 4,584 reoperations in 4,509 patients are reported. Recurrent reflux and dysphagia were the most frequent indications; intraoperative complications occurred in 21.4% and postoperative complications in 15.6%, with an overall mortality rate of 0.9%. The conversion rate in laparoscopic surgery was 8.7%. Mean(+/-SEM) duration of surgery was 177.4 +/- 10.3 min and mean hospital stay was 5.5 +/- 0.5 days. Symptomatic outcome was successful in 81.1% and was equal in the laparoscopic and conventional approach. Objective outcome was obtained in 24 studies (29.6%) and success was reported in 78.3%, with a slightly higher success rate in case of laparoscopy than with open surgery (85.8% vs. 78.0%).

CONCLUSION

This systematic review on redo antireflux surgery has confirmed that morbidity and mortality after redo surgery is higher than after primary surgery and symptomatic and objective outcome are less satisfactory. Data on objective results were scarce and consistency with regard to reporting outcome is necessary.

Laparoscopic redo fundoplication in children: failure causes and feasibility

PURPOSE

This retrospective study reports our experience in laparoscopic approach after failure of antireflux surgery. It evaluates the results and circumstances of failure of the initial procedure to understand indications of refundoplication.

METHODS

Four hundred seventeen patients were operated on for a gastroesophageal reflux disease (GERD) by laparoscopy in our unit from August 1993 to February 2005. Thirty redo procedures (7.19%) were performed. The indications were 24 (80%) recurrent reflux resistant to the medical treatment and 6 (20%) severe dysphagia resistant to iterative dilatations. The average age was 57.6 months. Nineteen patients (63%) were males and 11 patients (37%) were females. The time between the first and the redo procedure was an average of 16 months. Ten (33%) of them were neurologically impaired (NI); in 7 patients, a percutaneus gastrostomy was also associated. The techniques previously used were 13 Nissen, 7 Nissen-Rossetti, and 10 Toupet.

RESULTS

The redo procedure was performed by laparoscopy in 27 cases. A conversion was necessary in 3 children because of a difficult dissection. In the 24 cases of recurrent reflux, we realized a valve disassembly, reconstruction of hiatus and Nissen refundoplication. In 3 cases of dysphagia, the release of the hiatus needed a complete valve redo. The mean operative time was 140 minutes (110 to 240 minutes). The sole complication was a pleural perforation. All patients were fed on the first day. The mean duration of hospitalization was 3.1 days. The follow-up was from 48 months to 12 years. A new recurrent reflux occurred in 6 patients; 5 of them were NI.

CONCLUSION

The failure rate of the antireflux laparoscopic surgery is similar to the conventional surgery. The redo procedure is possible by laparoscopic with a success rate similar to the open redo surgery. The rate and morbidity of complications are acceptable and decrease with experienced surgeons. The indications of redo procedures should be similar to conventional surgery.

Vagotomy during hiatal hernia repair: a benign esophageal lengthening procedure

INTRODUCTION

This study describes the use of vagotomy in patients during complex laparoscopic esophageal surgery (e.g., reoperative antireflux surgery (rLARS) or paraesophageal hernia (PEH) repair) when, after extensive esophageal mobilization, the gastroesophageal junction cannot be made to reach the abdomen without tension. In doing so, we hope to understand the risk incurred by vagus nerve division in this setting in order to evaluate its role in managing the short esophagus.

METHODS

One hundred and sixty-six patients underwent rLARS or PEH repair between 1/1998 and 6/2003 at our institution. Clinical data was obtained from a prospectively maintained database and systematic patient questionnaires administered for this study. Follow-up was available for 102 (61%) of these patients, at a median of 19 months (range 6-69 months).

RESULTS

Fifty-two patients underwent rLARS while 50 patients underwent PEH repair. Thirty patients had a vagotomy during the course of their operation (Vag Group; 20 anterior, six posterior, four bilateral), 13 in the rLARS group (25%), and 17 in the PEH group (34%). The primary presenting symptoms for rLARS and PEH repair patients were improved in 89% in the Vag Group and 91% in the No Vag Group. Similarly, there was no difference in the severity of abdominal pain, bloating, diarrhea, or early satiety between the Vag and No Vag groups at follow-up. No patient required a subsequent operation for gastric outlet obstruction.

CONCLUSIONS

Vagotomy during rLARS and PEH repair does not lead to a higher rate delayed gastric emptying, dumping syndrome, or other side effects. Thus, we propose vagotomy to be a legitimate alternative to Collis gastroplasty when extensive mobilization of the esophagus fails to provide adequate esophageal length.

Subjective results and symptomatic outcome after fundoplication revision

OBJECTIVE

In a small proportion of patients, fundoplication fails and a reoperation is required. However, there are few reports on the symptomatic outcome after reoperative antireflux surgery. The aim of this study was to evaluate the results after fundoplication revision.

MATERIAL AND METHODS

All patients (n=71) undergoing fundoplication revision between 1997 and 2005 were included in this study. The follow-up data were collected both from the hospital records and during postoperative control visits, including a personal interview using a structured questionnaire; follow-up was completed by 61 patients (88.4%).

RESULTS

The primary fundoplications included both open (n=21) and laparoscopic (n=40) approaches; 92% (n=56) of the reoperations were open procedures. The morbidity rate was 21% and the reoperation rate 16%. Fifty-six percent (n=34) of the patients regarded the result of their reoperative surgery as excellent, good or satisfactory at a mean follow-up of 51 months; 66% of the patients had no significant reflux symptoms after re-fundoplication. With the benefit of hindsight, 77% of the patients would again choose to undergo re-fundoplication, but only 48% of the patients would again primarily choose surgical treatment. Mortality rate was 1.4% (n=1) and in three patients the reoperative treatment required total gastrectomy.

CONCLUSIONS

These suboptimal results show that surgical treatment for gastro-oesophageal reflux disease in general is far from being perfect and this is even more marked after reoperative antireflux surgery, as fundoplication revision can result in severe complications. This emphasizes the importance of proper patient selection for both initial and reoperative antireflux surgery.

Medium- and long-term outcome of laparoscopic redo fundoplication

BACKGROUND

For a small subset of patients, laparoscopic fundoplication fails, typically resulting in recurrent reflux or severe dysphagia. Although redo fundoplications can be performed laparoscopically, few studies have examined their long-term efficacy.

METHODS

Using a prospectively maintained database, the authors identified and contacted 41 patients who had undergone redo laparoscopic fundoplications at the University of Washington between 1996 and 2001. The median follow-up period was 50 months (range, 20-95 months). Current symptoms were compared with those acquired and entered into the authors' database preoperatively. Patients also were asked to return for esophageal manometry and pH testing.

RESULTS

All redo fundoplications were performed laparoscopically. There were no conversions. The most common indication for redo fundoplication was recurrent reflux. The most common anatomic abnormality was a herniated wrap. Heartburn improved in 61%, regurgitation in 69%, and dysphagia in 74% of the patients. Complete resolution of these symptoms was achieved, respectively, in 45%, 41% and 38% of these same patients. Overall, 68% of the patients rated the success of the procedure as either "excellent" or "good," and 78% said they were happy they chose to have it. For those who underwent reoperation for gastroesophageal reflux disease, distal esophageal acid exposure according to 24-h pH monitoring decreased after redo fundoplication from 15.7% +/- 18.1% to 3.4% +/- 3.6% (p = 0.041).

CONCLUSION

Although not as successful as primary fundoplication, a majority of patients can expect durable improvement in their symptoms with a laparoscopic redo fundoplication.

"Redo" fundoplications: satisfactory symptomatic outcomes with higher cost of care

INTRODUCTION

With ever greater numbers of fundoplications being undertaken, inevitably there will be an increase in the number of failed fundoplications, which will be considered for operative revision. This study was undertaken to compare the hospital costs of and outcomes after "redo" fundoplications to those of "first time" fundoplications.

METHODS

Patients undergoing anti-reflux surgery were prospectively followed. From 2000 to 2006, costs of and outcomes after 76 "redo" fundoplications were compared with 76 concurrent "first time" fundoplications. Prior to and after fundoplication, patients scored the frequency and severity of many symptoms, including dysphagia, chest pain, regurgitation, choking, and heartburn, using a Likert scale (0 = none/never, 10 = severe/always). The cost of care, including medical equipment, operating room expenses, and anesthesia was determined with standardization to 2006 cost and dollars. Data are presented as median (mean +/- standard deviation) where appropriate.

RESULTS

Prior to "redo" fundoplications, patients reported significantly greater dysphagia frequency and severity scores and significantly greater chest pain severity. DeMeester scores for patients undergoing "redo" fundoplications versus "first time" fundoplications were similar (45 (62 +/- 55.6) versus 39 (44 +/- 27.7)). After fundoplication, dysphagia frequency and severity significantly improved for all patients. Length of stay was significantly longer for patients requiring "redo" fundoplications [3 d (6 +/- 8.5) versus 1 d (3 +/- 7.6)]. Hospital costs for patients undergoing "redo" fundoplications were significantly greater.

CONCLUSIONS

Patients requiring re-operative fundoplications report more frequent and severe symptoms, especially of dysphagia, when compared with patients undergoing "first-time" fundoplications. Laparoscopic "redo" fundoplications are technically challenging, more expensive, and more morbid (e.g., longer hospital stays). However, symptoms of reflux and dysphagia are ameliorated with "redo" fundoplications and application of "redo" fundoplication is warranted.

Complications and frequency of redo antireflux surgery in Denmark: a nationwide study, 1997-2005

BACKGROUND

Outcomes after redo fundoplication (RF) in recurrent gastroesophageal reflux disease (GERD) are debatable, and they may include lower success rates with higher postoperative morbidity and mortality than outcomes after primary fundoplication (PF). However, data from large, nationwide studies are not available. Accordingly, the aim of the present study was to evaluate nationwide Danish data on RF in a nine-year period.

METHOD

Data in the period from 1997 through 2005 were extracted from the National Patient Register. The following information was procured: frequency of RF, rate of conversion to open surgery, rate of complications requiring reoperation, and 30-day mortality. Data for RF were compared to PF.

RESULTS

A total of 2589 fundoplications were performed in 2465 patients. Thus, 113 patients underwent a total of 124 RF (RF rate = 5.0%). Most RF (84.7%) were performed at high-volume departments. Patients who underwent RF were converted to open surgery more often (16.1% vs. 6.1% in PF) (P < 0.0001). The median postoperative hospital stay was 3 days after RF and 2 days after PF (P = 0.96). Following RF 1.6% of the patients had complications requiring surgery compared with 1.3% after PF (P = 0.79), and 30-day mortality was 0.81% after RF compared with 0.45% after PF (P = 0.57).

CONCLUSION

This nationwide Danish study showed a low rate of redo fundoplication and a similar morbidity and mortality rate after redo surgery compared with that of primary surgery.

Results of laparoscopic reoperation for failed antireflux surgery: does the indication for redo surgery affect the outcome?

Short and medium term outcomes from laparoscopic antireflux surgery are generally excellent. A small number of patients suffer recurrent reflux or intolerable side-effects and may require reoperation. In this paper we describe our experience of 35 laparoscopic reoperations from a single center. Data on patients undergoing antireflux surgery in our unit has been prospectively collected and includes more than 600 primary laparoscopic antireflux operations since 1993. Laparoscopic reoperations have been performed between 1996 and 2005 for patients suffering recurrent reflux, dysphagia or severe gas bloat symptomatic despite medical treatment. All patients underwent preoperative barium studies and endoscopy with selective manometry and pH studies. Symptomatic outcomes were evaluated at 6 weeks and 12 months with Visick scores. Anatomical results were assessed with barium studies at between 6 and 12 months. Thirty-five laparoscopic reoperations were performed in 20 women and 13 men (median age 56 years). Primary surgery had been performed in our unit in 27 (77%) and elsewhere in eight (23%). Median time from primary surgery was 28.5 months (5-360). Two patients underwent a second reoperation. Indication was recurrent reflux in 28 (80%), dysphagia in five (14%) and gas bloat in two (6%). Thirty-two of the 35 reoperations (91.4%) were completed laparoscopically, median operating time was 120.5 min (65-210) and median hospital stay 2 days. There was no mortality and there were only five minor complications. Twelve-month follow-up was available for 32 reoperations (91%). Overall good symptomatic outcomes were obtained in 26 (74%) Visick I or II at 6 weeks and 24 of 32 (75%) at 12 months. In reoperations for dysphagia/gas bloat there was a relative risk of 4.26 of a poor symptomatic outcome (Visick III or IV) at 12 months compared to those for recurrent reflux (P < 0.05, Fisher's exact test). Laparoscopic reoperation is feasible with low conversion rates and minimal morbidity for patients who have undergone previous abdominal or thoracic hiatal repair. Symptomatic outcomes are generally good, particularly if the indication is recurrent reflux.

Gastrectomy as a remedial operation for failed fundoplication

The decision for, and choice of, a remedial antireflux procedure after a failed fundoplication is a challenging clinical problem. Success depends upon many factors including the primary symptom responsible for failure, the severity of underlying anatomic and physiologic defects, and the number and type of previous remedial attempts. Satisfactory outcomes after reoperative fundoplication have been reported to be as low as 50%. Consequently, the ideal treatment option is not clear. The purpose of this study was to evaluate the outcome of gastrectomy as a remedial antireflux procedure for patients with a failed fundoplication. The study population consisted of 37 patients who underwent either gastrectomy (n = 12) with Roux-en-Y reconstruction or refundoplication (n = 25) between 1997-2005. Average age, M/F ratio, and preoperative BMI were not significantly different between the two groups. Outcome measures included perioperative morbidity, relief of primary and secondary symptoms, and the patients' overall assessment of outcome. Mean follow up was 3.5 and 3.3 years in the gastrectomy and refundoplication groups, respectively (p = 0.43). Gastrectomy patients had a higher prevalence of endoscopic complications of GERD (58% vs 4%, p = 0.006) and of multiple prior fundoplications than those having refundoplication (75% vs 24%, p = 0.004). Mean symptom severity scores were improved significantly by both gastrectomy and refundoplication, but were not significantly different from each other. Complete relief of the primary symptom was significantly greater after gastrectomy (89% vs 50%, p = 0.044). Overall patient satisfaction was similar in both groups (p = 0.22). In-hospital morbidity was higher after gastrectomy than after refundoplication (67% vs 20%, p = 0.007) and new onset dumping developed in two gastrectomy patients. In select patients with severe gastroesophageal reflux disease (GERD) and multiple previous fundoplications, primary symptom resolution occurs significantly more often after gastrectomy than after repeat fundoplication. Gastrectomy, however, is associated with higher morbidity. Gastrectomy is an acceptable treatment option for recurrent symptoms particularly when another attempt at fundoplication is ill advised, such as in the setting of multiple prior fundoplications or failed Collis gastroplasty.

Open vs laparoscopic partial posterior fundoplication. A prospective randomized trial

OBJECTIVE

This study compares outcomes following open and laparoscopic partial posterior fundoplication for gastroesophageal reflux disease concerning perioperative course, postoperative complications, symptomatic relief, recurrent disease, and the need for reinterventional surgery.

METHODS

A prospective randomized trial was performed. Pre- and postoperative testing included endoscopy, esophageal function testing, patient questionnaire, and clinical assessment. Patients were followed for three years.

MATERIALS

Ninety-three patients were randomized to open and 99 to laparoscopic surgery.

RESULTS

Complication rates were higher, and length of stay (LOS) [5 (3-36) vs 3 (1-12) days] and time off work [42 (12-76) vs 28 (0-108) days] was longer in the open group (p < 0.01). Early side effects and recurrences were more common (p < 0.05) in the laparoscopic group. One patient in the open group and 8 patients in the laparoscopic group required surgery for recurrent disease and 7 patients required surgery for incisional hernias after open surgery. Overall, at one and three years, there were no differences in patient-assessed satisfactory outcome (93.5/93.5 vs 88.8/90.8%) or reflux control (p = 0.53) between the open and laparoscopic groups.

CONCLUSIONS

The finding of fewer general complications, shorter length of stay and recovery, similar need for reoperations, and comparable 3-year outcomes, makes the laparoscopic approach the primary choice when considering surgical options for the treatment of gastroesophageal reflux disease (GERD).

Five-year subjective and objective results of laparoscopic and conventional Nissen fundoplication: a randomized trial

OBJECTIVE

The purpose of this prospective study was to compare the subjective and objective outcome of laparoscopic (LNF) and conventional Nissen fundoplication (CNF) up to 5 years after surgery as obtained in a multicenter randomized controlled trial.

SUMMARY OF BACKGROUND DATA

LNF is regarded as surgical treatment of first choice for refractory gastroesophageal reflux disease by many surgeons based on several short- and mid-term studies. The long-term efficacy of Nissen fundoplication, however, is still questioned as objective data gathered from prospective studies are lacking.

METHODS

From 1997 to 1999, 177 patients were randomized to undergo LNF or CNF. Five years after surgery, all patients were requested to fill in questionnaires and to undergo esophageal manometry and 24-hour pH-metry.

RESULTS

A total of 148 patients agreed to participate in the follow-up study: 79 patients after LNF and 69 after CNF. Of these, 97 patients (48 LNF, 49 CNF) consented to undergo esophageal manometry and 24-hour pH-metry. At 5 years follow-up, 20 patients had undergone reoperation: 12 after LNF (15%) and 8 after CNF (12%). There was no difference in subjective outcome, with overall satisfaction rates of 88% and 90%, respectively. Total esophageal acid exposure times (pH < 4) were 2.1% +/- 0.5% and 2.0% +/- 0.6%, respectively (P = 0.21). Antisecretory medication was taken daily in 14% and 16%, respectively (P = 0.29). There was no correlation between medication use and acid exposure and indices of symptom-reflux association (symptom index and symptom association probability). No significant differences between subjective and objective results at 3 to 6 months and results obtained at 5 years after surgery were found.

CONCLUSIONS

The effects of LNF and CNF on general state of health and objective reflux control are sustained up to 5 years after surgery and the long-term results of LNF and CNF are comparable. A substantial minority of patients in both groups had a second antireflux operation or took antisecretory drugs, although the use of those medications did not appear to be related to abnormal esophageal acid exposure.

Sub-diaphragmatic fascia: role in the recurrence of hiatal hernias

One of the most common causes of a failed Nissen fundoplication is disruption of the crural repair. We investigated the thickness of the subdiaphragmatic fascia overlying the right and left limb of the right crus in cadavers to determine any difference. Sub-diaphragmatic fascia specimens were obtained from three sites adjacent to the hiatus in 20 preserved cadavers. One square centimeter of fascia was excised 3 cm from the arch of the hiatus on each side and approximately 2-3 mm from the edge of the hiatal opening (labeled RL and LPL). A third sample was taken 1 cm from the arch of the hiatus on the left side (labeled LAL). The thickness of these tissues was measured. The mean tissue thickness of RL, LPL and LAL were 0.22 mm, 0.23 mm and 0.4 mm, respectively. There was no difference in tissue thickness between the lower specimens on both sides (RL vs. LPL); however, LAL was significantly thicker than both RL and LPL (P < 0.05). The thickness of the subdiaphragmatic fascia overlying the right and left limb of the right crus does not differ significantly in the region used for crus closure during antireflux surgery; however, the fascia on the left is thicker anteriorly.
