Symptomatic and functional outcome after laparoscopic reoperation for failed antireflux surgery

Does crural repair with biosynthetic mesh improve outcomes of revisional surgery for recurrent hiatal hernia?

BACKGROUND

Laparoscopic revisional surgery for recurrent hiatal hernia (HH) is technically demanding. Re-recurrences are common and esophageal hiatus mesh reinforcement might improve durability of the repair, thus minimizing the risk of re-herniation.

PURPOSE

Assess safety and effectiveness of simple suture repair (no mesh group) vs. crural augmentation with a biosynthetic absorbable mesh (mesh group) in patients with recurrent HH.

METHODS

Observational retrospective study from September 2012 to December 2022. Only patients undergoing redo surgery for previous failures of hiatal hernia repair were enrolled. Surgical failure was defined as symptomatic recurrent HH with > 2 cm of gastric tissue above the diaphragmatic impression at upper gastrointestinal endoscopy and/or swallow study. Gastro-Esophageal Reflux Disease Health-Related Quality of Life (GERD-HRQL) and Short Form-36 (SF-36) questionnaires were used to assess and preoperative and postoperative symptoms and quality of life.

RESULTS

One hundred four patients were included. Overall, 60 patients (57.7%) underwent mesh-reinforced cruroplasty, whereas 44 (42.3%) underwent simple suture cruroplasty. Mesh and no mesh groups had similar baseline demographics, symptoms, prevalence of esophagitis and Barrett's esophagus, and HH size. A composite crural repair was most commonly performed in the mesh group (38.3% vs. 20.5%; p = 0.07). In addition to cruroplasty, most patients (91%) underwent a Toupet fundoplication. The 90-day postoperative complication rate was 8.6%, and there was no mortality. Recurrent HH was diagnosed in 21 patients (20.2%) with a clinical trend toward reduced incidence in the mesh group (16.7% vs. 25%; p = 0.06). Compared to baseline, there was a statistically significant improvement of median GERD-HRQL score (p < 0.01) and all SF-36 items (p < 0.01).

CONCLUSIONS

Laparoscopic revisional surgery for recurrent HH is safe and effective. Selective use of biosynthetic mesh may protect from early recurrence and has the potential to reduce re-herniation in the long-term.

Current Status of Anti-Reflux Surgery as a Treatment for GERD

Anti-reflux surgery (ARS) is an efficient treatment option for gastroesophageal reflux disease (GERD). Despite growing evidence of the efficacy and safety of ARS, medications including proton pump inhibitors (PPIs) remain the most commonly administered treatments for GERD. Meanwhile, ARS can be an effective treatment option for patients who need medications continuously or for those who are refractory to PPI treatment, if proper candidates are selected. However, in practice, ARS is often regarded as a last resort for patients who are unresponsive to PPIs. Accumulating ARS-related studies indicate that surgery is equivalent to or better than medical treatment for controlling typical and atypical GERD symptoms. Furthermore, because of overall reduced medication expenses, ARS may be more cost-effective than PPI. Patients are selected for ARS based on endoscopic findings, esophageal acid exposure time, and PPI responsiveness. Although there is limited evidence, ARS may be expanded to include patients with normal acid exposure, such as those with reflux hypersensitivity. Additionally, other factors such as age, body mass index, and comorbidities are known to affect ARS outcomes; and such factors should be considered. Nissen fundoplication or partial fundoplication including Dor fundoplication and Toupet fundoplication can be chosen, depending on whether the patient prioritizes symptom improvement or minimizing postoperative symptoms such as dysphagia. Furthermore, efforts to reduce and manage postoperative complications and create awareness of the long-term efficacy and safety of the ARS are recommended, as well as adequate training programs for new surgeons.

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.

A retrospective multicenter analysis on redo-laparoscopic anti-reflux surgery: conservative or conversion fundoplication?

BACKGROUND

Nearly 20% of patients who undergo hiatal hernia (HH) repair and anti-reflux surgery (ARS) report recurrent HH at long-term follow-up and may be candidates for redo surgery. Current literature on redo-ARS has limitations due to small sample sizes or single center experiences. This type of redo surgery is challenging due to rare but severe complications. Furthermore, the optimal technique for redo-ARS remains debatable. The purpose of the current multicenter study was to review the outcomes of redo-fundoplication and to identify the best ARS repair technique for recurrent HH and gastroesophageal reflux disease (GERD).

METHODS

Data on 975 consecutive patients undergoing hiatal hernia and GERD repair were retrospectively collected in five European high-volume centers. Patient data included demographics, BMI, techniques of the first and redo surgeries (mesh/type of ARS), perioperative morbidity, perioperative complications, duration of hospitalization, time to recurrence, and follow-up. We analyzed the independent risk factors associated with recurrent symptoms and complications during the last ARS. Statistical analysis was performed using GraphPad Prism^® and R software^®.

RESULTS

Seventy-three (7.49%) patients underwent redo-ARS during the last decade; 71 (98%) of the surgeries were performed using a minimally invasive approach. Forty-two (57.5%) had conversion from Nissen to Toupet. In 17 (23.3%) patients, the initial Nissen fundoplication was conserved. The initial Toupet fundoplication was conserved in 9 (12.3%) patients, and 5 (6.9%) had conversion of Toupet to Nissen. Out of the 73 patients, 10 (13%) underwent more than one redo-ARS. At 8.5 (1-107) months of follow-up, patients who underwent reoperation with Toupet ARS were less symptomatic during the postoperative period compared to those who underwent Nissen fundoplication (p = 0.005, OR 0.038). Patients undergoing mesh repair during the redo-fundoplication (21%) were less symptomatic during the postoperative period (p = 0.020, OR 0.010). The overall rate of complications (Clavien-Dindo classification) after redo surgery was 11%. Multivariate analysis showed that the open approach (p = 0.036, OR 1.721), drain placement (p = 0.0388, OR 9.308), recurrence of dysphagia (p = 0.049, OR 8.411), and patient age (p = 0.0619, OR 1.111) were independent risk factors for complications during the last ARS.

CONCLUSIONS

Failure of ARS rarely occurs in the hands of experienced surgeons. Redo-ARS is feasible using a minimally invasive approach. According to our study, in terms of recurrence of symptoms, Toupet fundoplication is a superior ARS technique compared to Nissen for redo-fundoplication. Therefore, Toupet fundoplication should be considered in redo interventions for patients who initially underwent ARS with Nissen fundoplication. Furthermore, mesh repair in reoperations has a positive impact on reducing the recurrence of symptoms postoperatively.

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.

UK guidelines on oesophageal dilatation in clinical practice

These are updated guidelines which supersede the original version published in 2004. This work has been endorsed by the Clinical Services and Standards Committee of the British Society of Gastroenterology (BSG) under the auspices of the oesophageal section of the BSG. The original guidelines have undergone extensive revision by the 16 members of the Guideline Development Group with representation from individuals across all relevant disciplines, including the Heartburn Cancer UK charity, a nursing representative and a patient representative. The methodological rigour and transparency of the guideline development processes were appraised using the revised Appraisal of Guidelines for Research and Evaluation (AGREE II) tool.Dilatation of the oesophagus is a relatively high-risk intervention, and is required by an increasing range of disease states. Moreover, there is scarcity of evidence in the literature to guide clinicians on how to safely perform this procedure. These guidelines deal specifically with the dilatation procedure using balloon or bougie devices as a primary treatment strategy for non-malignant narrowing of the oesophagus. The use of stents is outside the remit of this paper; however, for cases of dilatation failure, alternative techniques-including stents-will be listed. The guideline is divided into the following subheadings: (1) patient preparation; (2) the dilatation procedure; (3) aftercare and (4) disease-specific considerations. A systematic literature search was performed. The Grading of Recommendations Assessment, Develop-ment and Evaluation (GRADE) tool was used to evaluate the quality of evidence and decide on the strength of recommendations made.

Pre-operative clinical and instrumental factors as antireflux surgery outcome predictors

Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. Many patients with mild reflux symptoms are treated adequately with lifestyle modifications, dietary changes, and low-dose proton pump inhibitors (PPIs). For those with refractory GERD poorly controlled with daily PPIs, numerous treatment options exist. Fundoplication is currently the most commonly performed antireflux operation for management of GERD. Outcomes described in current literature following laparoscopic fundoplication indicate that it is highly effective for treatment of GERD; early clinical studies demonstrate relief of symptoms in approximately 85%-90% of patients. However it is still unclear which factors, clinical or instrumental, are able to predict a good outcome after surgery. Virtually all demographic, esophagogastric junction anatomic conditions, as well as instrumental (such as presence of esophagitis at endoscopy, or motility patterns determined by esophageal high resolution manometry or reflux patterns determined by means of pH/impedance-pH monitoring) and clinical features (such as typical or atypical symptoms presence) of patients undergoing laparoscopic fundoplication for GERD can be factors associated with symptomatic relief. With this in mind, we sought to review studies that identified the factors that predict outcome after laparoscopic total fundoplication.

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.

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.

Minimally invasive Roux-en-Y gastric bypass for fundoplication failure offers excellent gastroesophageal reflux control

Roux-en-Y gastric bypass (RYGB) may represent a superior alternative to reoperative fundoplication in patients with symptomatic failure. Our goal was to assess early outcomes of patients after RYGB for failed fundoplication. Records of patients who underwent fundoplication takedown and RYGB from March 2007 to June 2013 were reviewed for demographics, comorbidities, operative findings, and perioperative outcomes. Data are reported as medians (range). Forty-five patients who had undergone 64 prior antireflux procedures (range, one to three fundoplications) were identified. Median patient age was 56 years (range, 25 to 72 years) with a body mass index of 33 kg/m(2) (range, 22 to 51 kg/m(2)). Most patients had comorbidities: hypertension (60%), anxiety/depression (44.4%), dyslipidemia (33.3%), asthma (31%), obstructive sleep apnea (26.7%), arthritis (22.2%), and diabetes (11.1%). Median symptom-free interval was 3 years (range, 0 to 25 years). All patients had an anatomic reason for failure: 83 per cent had a hiatal hernia and 35 per cent had a slipped Nissen fundoplication. The procedures were accomplished laparoscopically in 28, robotically in 13, and open in four cases. Median operative time was 367 minutes (range, 190 to 600 minutes) and estimated blood loss averaged 100 mL (range, 25 to 500 mL). Five patients (11%) required reoperation: one for an anastomotic leak, one for anastomotic obstruction, and three for early obstruction resulting from adhesions. Two patients developed respiratory failure requiring prolonged mechanical ventilation. Length of stay averaged four days (range, 1 to 33 days) with two readmissions: one for melena and one for vomiting and dehydration; neither required intervention. There was no mortality. At 11 months of follow-up (range, 2.3 to 54 months), 93.3 per cent of patients were symptom-free. When primary fundoplication for gastroesophageal reflux disease fails, fundoplication takedown and RYGB can be accomplished safely with minimally invasive techniques. The conversion to a RYGB has an acceptable perioperative morbidity and excellent early symptom control, and, therefore, should be considered for reoperative patients gastroesophageal reflux disease.

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.

Surgical treatment of GERD: where have we been and where are we going?

Surgical management of gastroesophageal reflux disease has evolved from relatively invasive procedures requiring open laparotomy or thoracotomy to minimally invasive laparoscopic techniques. Although side effects may still occur, with careful patient selection and good technique, the overall symptomatic control leads to satisfaction rates in the 90% range. Unfortunately, the next evolution to endoluminal techniques has not been as successful. Reliable devices are still awaited that consistently produce long-term symptomatic relief with correction of pathologic reflux. However, newer laparoscopically placed devices hold promise in achieving equivalent symptomatic relief with fewer side effects. Clinical trials are still forthcoming.

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.

Update on fundoplication for the treatment of GERD

Rudolph Nissen firstly implemented the idea of surgical treatment of gastroesophageal reflux more than 55 years ago. Today, laparoscopic fundoplication has become the surgical "golden standard" for the treatment of GERD. However, the initial enthusiasm and increasing number of performed procedures in the early 1990s declined dramatically between 2000 and 2006. Despite its excellent outcome, laparoscopic fundoplication is only offered to a minority of patients who are suffering from GERD. In this article we review the current indications for antireflux surgery, technical and intraoperative aspects of fundoplication, perioperative complications as well as short and long-term outcome. The focus is on the laparoscopic approach as the current surgical procedure of choice.

Efficacy and feasibility of laparoscopic redo fundoplication

BACKGROUND

Nearly 15% of patients who undergo anti-reflux surgery report recurrent symptoms on long-term follow-up and may be candidates for redo anti-reflux surgery (redo-ARS). In the last 10 years, several studies have evaluated the feasibility and short-term results of redo-ARS. The purpose of the present study was to critically review our experience with 102 redo fundoplications with short- to medium-term follow-up and special emphasis on subjective outcomes for redo-ARS.

METHODS

A retrospective chart analysis was done on consecutive 102 redo fundoplications performed between December 2003 and March 2008. The patients were divided into two groups, the open group (group A) and the laparoscopic (group B). Subjective symptom analysis was performed on an annual basis using a standard questionnaire.

RESULTS

There was no significant difference in mean age, body mass index (BMI), or time since first surgery between the two groups. Significant differences were noted between operative time, estimated blood loss, and median hospital stay between the two groups. A total of 16 patients were found to have short esophagus and underwent Collis gastroplasty. Complications included 11 hollow viscus injuries seen in group A and 13 such injuries in group B. There was significant improvement in all symptom scores in the two groups, along with a significant decrease in the use of acid suppression therapy. In the open group 58% of patients rated their satisfaction as excellent compared to 90% in the laparoscopic group.

CONCLUSIONS

This study clearly establishes the safety and efficacy of redo laparoscopic anti-reflux surgery with excellent outcomes after short- to medium-term follow-up.

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.

Reoperative antireflux surgery for dysphagia

BACKGROUND

Troublesome dysphagia is a common indication for redo antireflux surgery (Re-ARS). This study is aimed to analyze the efficacy of Re-ARS in resolving dysphagia and to identify risk factors for persistent or new-onset dysphagia after Re-ARS.

METHODS

A prospectively maintained database was retrospectively reviewed to identify patients after Re-ARS. Dysphagia severity was graded on a scale of 0 to 3 before and after Re-ARS based on responses to a standardized questionnaire. Patients reporting grade 2 or 3 symptoms were considered to have significant dysphagia. Satisfaction was graded using a 10-point analog scale.

RESULTS

Between December 2003 and July 2008, 106 patients underwent Re-ARS. Significant preoperative dysphagia was reported by 54 patients, and impaired esophageal motility was noted in 31 patients. Remedial surgery included redo fundoplication (n = 87), Collis gastroplasty with redo fundoplication (n = 16), and takedown of the fundoplication or hiatal closure alone (n = 3). At least 1 year follow-up period (mean 21.8 months) was available for 92 patients. For patients with significant preoperative dysphagia (n = 46), the mean symptom score declined from 2.35 to 0.78 (p < 0.0001). Persistent dysphagia was reported by 13 patients and new-onset dysphagia by 4 patients. No patients reported grade 3 dysphagia after Re-ARS. Dilations were used to treat 11 patients. Multivariate logistic regression analysis identified Collis gastroplasty (p = 0.03; adjusted odds ratio [OR], 5.74) and preoperative dysphagia (p = 0.01; adjusted OR, 6.80) as risk factors for significant postoperative dysphagia. The overall satisfaction score was 8.3, but certain subsets had significantly lower satisfaction scores. These subsets included patients with esophageal dysmotility (7.1; p = 0.04), patients who required Collis gastroplasty (7.0; p = 0.09), and patients with esophageal dysmotility who required Collis gastroplasty (5.0; p < 0.01).

CONCLUSION

Although dysphagia is a common symptom among patients requiring Re-ARS, intervention provides a significant benefit. Patients with preoperative dysphagia, especially those requiring Collis gastroplasty, are at increased risk for persistent dysphagia and decreased satisfaction after Re-ARS.

Gastroesophageal reflux disease: medical or surgical treatment?

BACKGROUND

Gastroesophageal reflux disease is a common condition with increasing prevalence worldwide. The disease encompasses a broad spectrum of clinical symptoms and disorders from simple heartburn without esophagitis to erosive esophagitis with severe complications, such as esophageal strictures and intestinal metaplasia. Diagnosis is based mainly on ambulatory esophageal pH testing and endoscopy. There has been a long-standing debate about the best treatment approach for this troublesome disease.

METHODS AND RESULTS

Medical treatment with PPIs has an excellent efficacy in reversing the symptoms of GERD, but they should be taken for life, and long-term side effects do exist. However, patients who desire a permanent cure and have severe complications or cannot tolerate long-term treatment with PPIs are candidates for surgical treatment. Laparoscopic antireflux surgery achieves a significant symptom control, increased patient satisfaction, and complete withdrawal of antireflux medications, in the majority of patients.

CONCLUSION

Surgical treatment should be reserved mainly for young patients seeking permanent results. However, the choice of the treatment schedule should be individualized for every patient. It is up to the patient, the physician and the surgeon to decide the best treatment option for individual cases.

Anatomical failure following laparoscopic antireflux surgery (LARS): does it really matter?

INTRODUCTION

Failure rates of laparoscopic antireflux surgery (LARS) vary from 2-30%. A degree of anatomical failure is common, and the most common failure is intrathoracic wrap herniation. We have assessed anatomical integrity of the crural repair and wrap using marking Liga clips placed at the time of surgery and compared this with symptomatic outcome.

PATIENTS AND METHODS

A prospective study was undertaken on 50 patients who underwent LARS in a single centre over a 3-year period. Each had an X-ray on the first postoperative day and a barium swallow at 6 months at which the distance was measured between the marking Liga clips. An increase in interclip distance of > 25-49% was deemed 'mild separation', and an increase of > 50% 'moderate separation'. Patients completed a standardised symptom questionnaire at 6 months.

RESULTS

At 6 months' postoperatively, 22% had mild separation of the crural repair with a mean Visick score of 1.18, and 54% had moderate separation with a mean Visick score of 1.26. Mild separation of the wrap occurred in 28% with a mean Visick score of 1.21 and 22% moderate separation with a mean Visick score of 1.18. Three percent had mild separation of both the crural repair and wrap with a mean Visick score of 1.0, and 16% moderate separation with a mean Visick score of 1.13. Of patients, 14% had evidence of some degree of failure on barium swallow but only one of these was significant intrathoracic migration of the wrap which was symptomatic and required re-do surgery.

CONCLUSIONS

The prevalence of some form of anatomical failure, as determined by an increase in the interclip distance, is high at 6 months' postoperatively following LARS. However, this does not seem to correlate with a subjective recurrence of symptoms.

Laparoscopic upper gut surgery

Australian surgeons have been prominent in the introduction, development, and consolidation of laparoscopic surgery of the upper gut. In doing this, some of the very best principles of surgical innovation have been in evidence: preliminary animal work in which to test hypotheses and techniques, followed by careful application and documentation in the clinical setting, randomized clinical trials and finally academic reporting and ongoing development. This review documents the introduction of laparoscopic surgery for gastroesophageal reflux, hiatus hernia, achalasia, gastroesophageal malignancy, obesity, and a range of emergency conditions in Australia. Those involved are regarded as world leaders in their field. A vital component of this success has been the close cooperation between surgeons and gastroenterologists within the Gastroenterological Society of Australia.

Laparoscopic revision of failed fundoplication and hiatal herniorraphy

OBJECTIVE

The aim of this study was to evaluate the mechanisms of failure after laparoscopic fundoplication and the results of revision laparoscopic fundoplication.

BACKGROUND

Laparoscopic Nissen fundoplication has become the most commonly performed antireflux procedure for the treatment of gastroesophageal reflux disease, with success rates from 90 to 95%. Persistent or new symptoms often warrant endoscopic and radiographic studies to find the cause of surgical failure. In experienced hands, reoperative antireflux surgery can be done laparoscopically. We performed a retrospective analysis of all laparoscopic revision of failed fundoplications done by the principle author and the respective fellow within the laparoscopic fellowship from 1992 to 2006.

METHODS

A review was performed on patients who underwent laparoscopic revision of a failed primary laparoscopic fundoplication.

RESULTS

Laparoscopic revision of failed fundoplication was performed on 68 patients between 1992 and 2006. The success rate of the laparoscopic redo Nissen fundoplication was 86%. Symptoms prior to the revision procedure included heartburn (69%), dysphagia (8.8%), or both (11.7%). Preoperative evaluation revealed esophagitis in 41%, hiatal hernia with esophagitis in 36%, hiatal hernia without esophagitis in 7.3%, stenosis in 11.74%, and dysmotility in 2.4%. The main laparoscopic revisions included fundoplication alone (41%) or fundoplication with hiatal hernia repair (50%). Four gastric perforations occurred; these were repaired primarily without further incident. An open conversion was performed in 1 patient. Length of stay was 2.5 +/- 1.0 days. Mean follow-up was 22 months (range, 6-42), during which failure of the redo procedure was noted in 9 patients (13.23%).

CONCLUSION

Laparoscopic redo antireflux surgery, performed in a laparoscopic fellowship program, produces excellent results that approach the success rates of primary operations.

Long-term outcomes of revisional surgery following laparoscopic fundoplication

BACKGROUND

A small proportion of patients who have laparoscopic antireflux procedures require revisional surgery. This study investigated long-term clinical outcomes.

METHODS

Patients requiring late revisional surgery following laparoscopic fundoplication for gastro-oesophageal reflux were identified from a prospective database. Long-term outcomes were determined using a questionnaire evaluating symptom scores for heartburn, dysphagia and satisfaction.

RESULTS

The database search found 109 patients, including 98 (5.6 per cent) of 1751 patients who had primary surgery in the authors' unit. Indications for surgical revision were dysphagia (52 patients), recurrent reflux (36), mechanical symptoms related to paraoesophageal herniation (16) and atypical symptoms (five). The median time to revision was 26 months. Outcome data were available for 104 patients (median follow-up 66 months) and satisfaction data for 102, 88 of whom were highly satisfied (62.7 per cent) or satisfied (23.5 per cent) with the outcome. Patients who had revision for dysphagia had a higher incidence of poorly controlled heartburn (20 versus 2 per cent; P = 0.004), troublesome dysphagia (16 versus 6 per cent; P = 0.118) and a lower satisfaction score (P = 0.023) than those with recurrent reflux or paraoesophageal herniation.

CONCLUSION

Revisional surgery following laparoscopic fundoplication can produce good long-term results, but revision for dysphagia has less satisfactory outcomes.

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.

Persistent dysphagia after laparoscopic fundoplication for gastro-esophageal reflux disease

Persistent postoperative dysphagia is a potentially severe complication of fundoplication for gastroesophageal reflux disease (GERD). The aim of this retrospective study was to analyze our experience of laparoscopic fundoplication for GERD in 276 consecutive patients, to determine the frequency of postoperative dysphagia and assess treatments and outcomes. There was no relation between preoperative dysphagia, present in 24 patients (8.7%), and postoperative DeMeester grade 2 or 3 dysphagia, present in 25 patients (9.1%). Ten (3.6%) patients had clinically significant postoperative dysphagia, eight (2.9%) underwent esophageal dilation, with symptom improvement in five. Four (1.4%) of our patients (two with failed dilation) and 11 patients receiving antireflux surgery elsewhere, underwent re-operation for persistent dysphagia 12 months (median) after the first operation. DeMeester grade 0 or 1 dysphagia was obtained in 10/13 evaluable patients. Our experience is fully consistent with that of the recent literature. Redo surgery is necessary in only a small fraction of operated patients with GERD with good probability of resolving the dysphagia. Best outcomes are obtained when an anatomical cause of the dysphagia is documented preoperatively.

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.

Pseudoachalasia occurring after laparoscopic Nissen fundoplication and crural mesh repair

BACKGROUND

Benign esophageal pseudoachalasia is a rare condition.

DISCUSSION

We report the case of a 70-year-old man who complained of severe dysphagia after laparoscopic Nissen fundoplication and crural mesh repair performed for long-standing gastroesophageal reflux disease. Severe dysphagia and nocturnal aspiration developed soon after the operation. A marked dilatation of the esophageal body and a manometric pattern resembling achalasia was documented.

RESULTS

Endoscopic balloon dilatation was ineffective. Five months after the initial operation, the patient underwent revisional laparoscopic surgery that consisted of Nissen's wrap takedown, enlargement of the hiatus with partial resection of the mesh, Heller myotomy, and Dor fundoplication. After a 2-year follow-up, the patient is doing well and is free of symptoms.
