Nissen vs Toupet laparoscopic fundoplication

Systematic review of the perioperative classification, diagnosis, description and repair of hiatus hernias in randomized controlled trials

Hiatus hernias (HH) are a common cause of symptoms and complications, with considerable variation in anatomy, function, diagnosis and treatment. We undertook the first systematic review to appraise how HH are diagnosed and classified in the literature, using randomized controlled trials as a sample. A search was performed in July 2021of the PubMed, EMBASE and Cochrane Central Register of Controlled Trials, and 2832 articles were identified and 64 were included. Median Jadad score was 2. Studies demonstrated considerable variation in diagnosis, classification and minimum surgical steps. The commonest classifications before surgery were axial length and the Type I-IV classification, variably assessed by endoscopy and contrast swallow. Intra-operatively, the commonest classification was type I-IV. A minority used more than one classification, or alternatives such as defect size and Hill classification. Most studies reported minimum steps, but these varied. Only a minority reported criteria for diagnosing recurrence. Using randomized controlled trials to appraise the highest quality evidence in the literature, we found considerable variation and inconsistency in the way HH are diagnosed and classified. This lack of a 'common language' has significant impacts for the generalizability of evidence, study synthesis and design. We propose the development of an internationally accepted classification. We wish to confirm that there are no known conflicts of interest associated with this publication and there has been no significant financial support for this work that could have influenced its outcome. We confirm that the manuscript has been read and approved by all named authors and that there are no other persons who satisfied the criteria for authorship but are not listed. We further confirm that the order of authors listed in the manuscript has been approved by all of us.

Laparoscopic floppy Nissen fundoplication with valve calibration: a safe and efficient procedure

PURPOSES

A floppy Nissen fundoplication with valve calibration (FNF-VC) performed by laparotomy has been described, to reduce postoperative dysphagia and gas bloating after 360°-fundoplication. As laparoscopy is the gold standard for fundoplication, this study reports the first results of a modified FNF-VC adapted for laparoscopy (LFNF).

METHODS

Seventy-two consecutive patients, who underwent LFNF for refractory GERD between 2012 and 2021, were included. Postoperative outcomes and quality of life (QoL) by GERSS, GERD-HRQL, and GIQLI scores before and after surgery were assessed.

RESULTS

The main symptoms were pyrosis (81%), regurgitation (39%), Ear-Nose-Throat symptoms (22%), and thoracic pain (24%). Hiatal hernia was present in 85% (n = 61) of the patients. There was no postoperative mortality, and the severe postoperative morbidity rate (Dindo-Clavien ≥ III) was 6%. After a median follow-up of 3.6 years, only 8% of patients were still taking proton-pump inhibitors. Long-term residual dysphagia was noted in 15% of the patients, but none required reoperation or interventional endoscopic procedures. QoL improved, with a significant reduction in GERSS and GERD-HRQL scores and a postoperative GIQLI of 101.75 (75-117.5).

CONCLUSION

This series reports the safety and efficacy of an FNF-VC adapted for laparoscopy to treat GERD with a limited rate of residual dysphagia.

Short-term results of laparoscopic anti-reflux surgery with the RefluxStop device in patients with gastro-esophageal reflux disease and ineffective esophageal motility

PURPOSE

In gastro-esophageal reflux disease (GERD) requiring surgical treatment, concomitant ineffective esophageal motility (IEM) is a decisive factor in surgical planning, due to concern regarding dysphagia. Anti-reflux surgery with the RefluxStop device is a promising technique. We assessed initial feasibility and clinical outcomes of RefluxStop surgery in patients with GERD and IEM.

METHODS

Retrospective analysis of patients with GERD, hiatal hernia (HH), and IEM, who underwent surgery with RefluxStop at our institution and achieved 12-month follow-up. Technique feasibility was assessed, in addition to symptom resolution (GERD-HRQL questionnaire), adverse events, HH recurrence, dysphagia, and patient satisfaction. Placement of the device was confirmed by video fluoroscopy on postoperative day 1, and at 3 and 12 months.

RESULTS

Between June 2020 and November 2022, 20 patients with IEM underwent surgery with RefluxStop and completed 12-month follow-up. All patients reported typical symptoms of GERD, and 12 had preoperative dysphagia. The median HH length was 4.5 cm (IQR, 3.75-5). The median operating time was 59.5 min (IQR, 50.25-64) with no implant-related intra- or postoperative complications. No HH recurrence was observed. One patient reported persistent left-sided thoracic pain at 11 months post-surgery, which required diagnostic laparoscopy and adhesiolysis. Three patients reported severe postoperative dysphagia: balloon dilatation was performed towards resolution. The mean GERD-HRQL scores improved (from 40.7 at baseline to 4.8 at 3 months and 5.7 at 12 months (p <0.001)).

CONCLUSION

RefluxStop surgery was feasible and offered effective treatment for this group of patients with GERD and IEM. All patients had complete resolution or significant improvement of GERD symptoms, and 90% of them were satisfied with their quality of life 1 year after surgery.

Impedance planimetry (EndoFLIPTM) and surgical outcomes after Hill compared to Toupet fundoplication

INTRODUCTION

Endoluminal functional lumen imaging probe (EndoFLIP) provides a real-time assessment of gastroesophageal junction (GEJ) compliance during fundoplication. Given the limited data on EndoFLIP measurements during the Hill procedure, we investigated the impact of the Hill procedure on GEJ compliance compared to Toupet fundoplication.

METHODS

Patients who underwent robotic Hill or Toupet fundoplication with intraoperative EndoFLIP between 2017 and 2022 were included. EndoFLIP measurements of the GEJ included cross sectional surface area (CSA), intra-balloon pressure, high pressure zone length (HPZ), distensibility index (DI), and compliance. Subjective reflux symptoms, gastroesophageal reflux disease-health related quality of life (GERD-HRQL) score, and dysphagia score were assessed pre-operatively as well as at short- and longer-term follow-up.

RESULTS

One-hundred and fifty-four patients (71.9%) had a Toupet fundoplication while sixty (28%) patients underwent the Hill procedure. The CSA [27.7 ± 10.9 mm2 vs 42.2 ± 17.8 mm2, p < 0.0001], pressure [29.5 ± 6.2 mmHg vs 33.9 ± 8.5 mmHg, p = 0.0009], DI [0.9 ± 0.4 mm2/mmHg vs 1.3 ± 0.6 mm2/mmHg, p = 0.001], and compliance [25.9 ± 12.8 mm3/mmHg vs 35.4 ± 13.4 mm3/mmHg, p = 0.01] were lower after the Hill procedure compared to Toupet. However, there was no difference in post-fundoplication HPZ between procedures [Hill: 2.9 ± 0.4 cm, Toupet: 3.1 ± 0.6 cm, p = 0.15]. Follow-up showed no significant differences in GERD-HRQL scores, overall dysphagia scores or atypical symptoms between groups (p > 0.05).

CONCLUSION

The Hill procedure is as effective to the Toupet fundoplication in surgically treating gastroesophageal reflux disease (GERD) despite the lower CSA, DI, and compliance after the Hill procedure. Both procedures led to DI < 2 mm2/mmHg with no significant differences in dysphagia reporting (12-24) months after the procedure. Further studies to elucidate a cutoff value for DI for postoperative dysphagia development are still warranted.

Laparoscopic Nissen Versus Toupet Fundoplication for Short- and Long-Term Treatment of Gastroesophageal Reflux Disease: A Meta-Analysis and Systematic Review

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) is the most common standard technique worldwidely for Gastroesophageal reflux disease (GERD). Another type of fundoplication, laparoscopic Toupet fundoplication (LTF), intends to reduce incidence of postoperative complications. A systematic review and meta-analysis are required on short- and long-term outcomes based on randomized controlled trials (RCTs) between LNF and LTF.

METHODS

We searched databases including PubMed, Cochrane, Embase, and Web of Knowledge for RCTs comparing LNF and LTF. Outcomes included postoperative reflux recurrence, postoperative heartburn, dysphagia and postoperative chest pain, inability to belch, gas bloating, satisfaction with intervention, postoperative esophagitis, postoperative DeMeester scores, operating time (min), in-hospital complications, postoperative use of proton pump inhibitors, reoperation rate, postoperative lower oesophageal sphincter (LOS) pressure (mmHg). We assessed data using risk ratios and weighted mean differences in meta-analyses.

RESULTS

Eight eligible RCTs comparing LNF (n = 605) and LTF (n = 607) were identified. There were no significant differences between the LNF and LTF in terms of postoperative reflux recurrence, postoperative heartburn, postoperative chest pain, satisfaction with intervention, reoperation rate in short and long term, in-hospital complications, esophagitis in short term, and gas bloating, postoperative DeMeester scores, postoperative use of proton pump inhibitors, reoperation rate in long term. LTF had lower LOS pressure (mmHg), fewer postoperative dysphagia and inability to belch in short and long term and gas bloating in short term compared to LNF.

CONCLUSION

LTF were equally effective at controlling reflux symptoms and improving the quality of life, but with lower rate of complications compared to LNF. We concluded that LTF surgical treatment was superior for over 16 years old patients with typical symptoms of GERD and without upper abdominal surgical history upon high-level evidence of evidence-based medicine.

Prolapse of duodenal bulb from esophageal hiatal hernia: A case report

INTRODUCTION

The number of patients with hiatal hernia has increased. Paraesophageal and mixed hiatal hernias are absolute indications for surgical treatment due to the possibility of blood flow disturbances to the stomach and other organs.

CASE PRESENTATION

A 77-year-old woman with a history of type IV esophageal hiatal hernia (under observation), multiple operations presented with a chief complaint of vomiting. She was diagnosed with a type IV esophageal hiatal hernia with incarceration of the duodenal bulb into the mediastinum. Although the incarceration was relieved with conservative treatment, the patient was at a high risk for recurrence; therefore, surgical hernia repair was performed. Intraoperatively, the hernia portal was severely dilated and the duodenal bulb was easily accessible to the mediastinum due to its high mobility. Fundoplication was performed using the Toupet procedure. No stenosis at the fundoplication site was observed on intraoperative upper gastrointestinal endoscopy.

DISCUSSION

The causes of prolapse and incarceration of the duodenal bulb into the mediastinum were speculated to be weakening of the tissue due to aging, adhesion of the omentum to the hernia portal due to chronic prolapse of the stomach toward the mediastinum, increased intra-abdominal pressure due to a rounded back, and anatomical shortening of the distance between the esophageal hiatus and the duodenal bulb. The Toupet method was used as it is associated with a lower incidence of dysphagia.

CONCLUSION

Further investigation is needed to determine the best surgical technique.

The Angle of His as a Measurable Element of the Anti-reflux Mechanism

BACKGROUND

Gastroesophageal reflux disease (GERD) is a common condition, resulting from the loss of the anti-reflux barrier. Laparoscopic fundoplication is the surgical procedure of choice for treatment of GERD; however, there remains a debate on the exact mechanism through which it prevents reflux.

OBJECTIVES

Our aim was to understand the relationship between reflux, fundoplication, and the angle of His on an experimental model.

METHODS

The study was conducted on four groups of fresh explanted swine stomachs: control group, myotomy, myotomy with Nissen fundoplication, and myotomy with Toupet fundoplication. The stomachs were placed in a specially designated container on an inclinable platform which would increase the hydrostatic pressure on the esophago-gastric junction. Measurements of the angle of His using fluoroscopy and the esophago-gastric orifice area using endoscopy were performed, and the occurrence of reflux was documented.

RESULTS

Each group of the study contained nine swine stomachs. In the control and myotomy groups, the angle became wider as the incline level increased the pressure and was significantly different between the groups (p < .001). Both groups demonstrated an increase in the orifice area as the incline level increased the pressure. There was a significant correlation between the angle of His and the area of the esophago-gastric orifice (p < .001). In the control group, the reflux began at the 0°. In the myotomy group, it began at the + 15° incline (less pressure). Reflux rarely occurred in the Nissen and Toupet groups, with the breaking point being mostly defined as "beyond - 30°". A significant difference was noted in the occurrence of reflux between fundoplication and the non-fundoplication groups (p < 0.001), while there was no significant difference between the Toupet and Nissen groups (p = 0.134). Analysis showed a significant independent correlation between both the angle of His and the orifice area with the presence of reflux (p = .002 and p = .024 respectively).

CONCLUSIONS

In this study, we developed an experimental model to enable careful evaluation of the elements of the anti-reflux mechanism, of which, the angle of His has a measurable element. We demonstrated that as the angle of His becomes wider the esophago-gastric orifice area becomes larger. Additionally, a wider angle of His and a larger esophago-gastric orifice area were correlated independently with more reflux. This suggests that the fundoplication creates an acute angle of His which is correlated with a smaller area of the esophago-gastric orifice and eventually with a lower incidence of reflux.

Nissen Versus Toupet Fundoplication For Gastro-oesophageal Reflux Disease, Short And Long-term Outcomes. A Systematic Review And Meta-analysis

BACKGROUND

Gastroesophageal reflux disease (GERD) remains one of the most commonly encountered gastrointestinal disorders. Proton pump inhibitors still show an inadequate effect on about 10% to 40% of the patients. Laparoscopic antireflux surgery is the surgical alternative for managing GERD in patients who are not responding to proton pump inhibitors.

AIM OF THE STUDY

This study objected at comparing laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication (LTF) concerning the short-term and long-term outcomes.

PATIENTS AND METHODS

This is a systematic review and meta-analysis that evaluated the studies comparing between Nissen fundoplication and LTF for the treatment of GERD. Studies were obtained by searching on the EMBASE, the Cochrane Central Register of Controlled Trials, and PubMed central database.

RESULTS

The LTF group showed significantly longer operation time, less postoperative dysphagia and gas bloating, less pressure on the lower esophageal sphincter, and higher Demeester scores. No statistically significant differences were found between the 2 groups in the perioperative complications, the recurrence of GERD, the reoperation rate, the quality of life, or the reoperation rate.

CONCLUSION

LTF is favored for the surgical treatment of GERD being of lower postoperative dysphagia and gas bloating rates. These benefits were not at the expense of significantly additional perioperative complications or surgery failure.

Multi-society consensus conference and guideline on the treatment of gastroesophageal reflux disease (GERD)

BACKGROUND

Gastroesophageal reflux disease (GERD) is one of the most common diseases in North America and globally. The aim of this guideline is to provide evidence-based recommendations regarding the most utilized and available endoscopic and surgical treatments for GERD.

METHODS

Systematic literature reviews were conducted for 4 key questions regarding the surgical and endoscopic treatments for GERD in adults: preoperative evaluation, endoscopic vs surgical or medical treatment, complete vs partial fundoplication, and treatment for obesity (body mass index [BMI] ≥ 35 kg/m²) and concomitant GERD. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Recommendations for future research were also proposed.

RESULTS

The consensus provided 13 recommendations. Through the development of these evidence-based recommendations, an algorithm was proposed for aid in the treatment of GERD. Patients with typical symptoms should undergo upper endoscopy, manometry, and pH-testing; additional testing may be required for patients with atypical or extra-esophageal symptoms. Patients with normal or abnormal findings on manometry should consider undergoing partial fundoplication. Magnetic sphincter augmentation or fundoplication are appropriate surgical procedures for adults with GERD. For patients who wish to avoid surgery, the Stretta procedure and transoral incisionless fundoplication (TIF 2.0) were found to have better outcomes than proton pump inhibitors alone. Patients with concomitant obesity were recommended to undergo either gastric bypass or fundoplication, although patients with severe comorbid disease or BMI > 50 should undergo Roux-en-Y gastric bypass for the additional benefits that follow weight loss.

CONCLUSION

Using the recommendations an algorithm was developed by this panel, so that physicians may better counsel their patients with GERD. There are certain patient factors that have been excluded from included studies/trials, and so these recommendations should not replace surgeon-patient decision making. Engaging in the identified research areas may improve future care for GERD patients.

Outcomes of partial fundoplication for GERD-related allograft decline after lung transplantation

INTRODUCTION

Gastroesophageal reflux disease contributes to allograft decline secondary to bronchiolitis obliterans after lung transplantation. Antireflux surgery (ARS) slows the decline in lung function related to GERD. ARS operations range from Nissen fundoplications to partial fundoplications, such as the Toupet and Dor. Research in the general population has indicated that partial fundoplication is effective at controlling reflux. We explored lung function and reflux outcomes in a cohort of lung transplant patients who received partial fundoplications.

METHODS

Data from an institutional lung transplant registry was reviewed for patients between 2009 and 2020 who underwent fundoplication after transplant. Lung transplant patients underwent routine pulmonary function testing. Patients with FEV1 values within 180 days pre-fundoplication and two years post-fundoplication were included in the analysis. All patients referred for fundoplication underwent esophageal pH testing, manometry, UGI, and EGD. Most patients underwent Toupet fundoplication, but those with severe dysmotility underwent Dor fundoplication.

RESULTS

53 patients were included in the analysis. Median time to fundoplication after transplant was 403 days. 48 patients underwent Toupet fundoplication. Five underwent Dor fundoplication. 40% of patients had abnormal high-resolution manometry. A linear mixed-effects model tested for a change in FEV1 trajectory up to two years post-fundoplication with an auto-regressive correlation structure. Post-fundoplication FEV1 values decreased by 7 mL per month, and suggested a slow in the decline by 2 mL per month, but this was not significant (p = 0.8). In patients for whom postoperative DeMeester scores were available (19), there was a decline in acid exposure from a median of 45.8 to 1.8 after ARS (p = 0.0003).

CONCLUSION

Although our results did not reach statistical significance, there was a trend towards a decrease in the rate of decline of allograft function before and after partial fundoplication. In the patients whom results were available, a partial fundoplication appropriately controlled acid exposure.

A Rare Occurrence of Rotational Retro-Esophageal Gastric Body Herniation Through a Nissen Fundoplication

Anti-reflux procedures have become a mainstay in managing gastroesophageal reflux disease (GERD) and hiatal hernia. Unfortunately, post-operative events such as breakdown of the wrap, downward slippage, or transdiaphragmatic herniation of an intact wrap cause these procedures to fail and create complications such as recurrent hiatal hernia and reflux dysphagia, regurgitation, and obstruction requiring revision surgery. We discuss a case of a rotational retro-esophageal herniation of the gastric body through a Nissen fundoplication presenting as obstruction, dysphagia, and regurgitation, highlighting the peculiar nature of this presentation and the ease of misdiagnosis given its rarity.

Surgical treatment of recalcitrant gastroesophageal reflux disease in patients with systemic sclerosis: a systematic review

Introduction

Gastroesophageal reflux disease (GERD) is frequently seen in patients with systemic sclerosis (SSc). Long-standing GERD may cause esophagitis, long-segment strictures, and Barrett’s esophagus and may worsen pre-existing pulmonary fibrosis with an increased risk of end-stage lung disease. Surgical treatment of recalcitrant GERD remains controversial. The purpose of this systematic review was to summarize the current data on surgical treatment of recalcitrant GERD in SSc patients.

Materials and methods

A systematic literature review according to PRISMA and MOOSE guidelines. PubMed, EMBASE, and Web of Science databases were consulted.

Results

A total of 101 patients were included from 7 studies. The age ranged from 34 to 61 years and the majority were females (73.5%). Commonly reported symptoms were heartburn (92%), regurgitation (77%), and dysphagia (74%). Concurrent pulmonary disease was diagnosed in 58% of patients. Overall, 63 patients (62.4%) underwent open fundoplication, 17 (16.8%) laparoscopic fundoplication, 15 (14.9%) Roux en-Y gastric bypass (RYGB), and 6 (5.9%) esophagectomy. The postoperative follow-up ranged from 12 to 65 months. Recurrent symptoms were described in up to 70% and 30% of patients undergoing fundoplication and RYGB, respectively. Various symptoms were reported postoperatively depending on the type of surgical procedures, anatomy of the valve, need for esophageal lengthening, and follow-up.

Conclusions

The treatment of recalcitrant GERD in SSc patients is challenging. Esophagectomy should be reserved to selected patients. Minimally invasive RYGB appears feasible and safe with promising preliminary short-term results. Current evidence is scarce while a definitive indication about the most appropriate surgical treatment is lacking.

Complete vs partial fundoplication: a laboratory measurement of functionality and effectiveness

BACKGROUND

Complete or partial fundoplication remains controversial for the surgical treatment of GERD. While partial fundoplication is considered less effective, it is associated with less post-operative dysphagia and gas bloating compared with complete fundoplication.

AIM

To compare the mechanical efficiency of the three different types of fundoplication.

MATERIAL AND METHOD

Two studies of the LES were performed on explanted stomachs: distensibility and failure point. Measurements were taken before and after fundoplication.

RESULTS

There was no difference in distensibility between Nissen and Toupet fundoplication, however, the EGJ was more distensible following Dor fundoplication. According to failure point measurements, Nissen fundoplication was significantly more effective than Toupet, Toupet was significantly more effective than Dor (p = .016, p = .017, respectively).

CONCLUSIONS

There were significant differences in distensibility between Dor and both Nissen and Toupet, however no statistical difference between Toupet and Nissen. There was a significant difference in effectiveness between all three types of fundoplication according to the failure point. These laboratory findings demonstrate that the mechanical orientation of Nissen and Toupet have similar functionality suggesting that Toupet is as good as Nissen. While in clinical studies Toupet has fewer post-operative complications these findings support the proponents of Toupet for GERD. Abbreviation: GERD: Gastroesophageal reflux disease.

Laparoscopic Fundoplication Is Effective Treatment for Patients with Gastroesophageal Reflux and Absent Esophageal Contractility

BACKGROUND

Anti-reflux surgery in the setting of preoperative esophageal dysmotility is contentious due to fear of persistent long-term dysphagia, particularly in individuals with an aperistaltic esophagus (absent esophageal contractility). This study determined the long-term postoperative outcomes following fundoplication in patients with absent esophageal contractility versus normal motility.

METHODS

A prospective database was used to identify all (40) patients with absent esophageal contractility who subsequently underwent fundoplication (36 anterior partial, 4 Nissen). Cases were propensity matched based on age, gender, and fundoplication type with another 708 patients who all had normal motility. Groups were assessed using prospective symptom assessment questionnaires to assess heartburn, dysphagia for solids and liquids, regurgitation, and satisfaction with surgery, and outcomes were compared.

RESULTS

Across follow-up to 10 years, no significant differences were found between the two groups for any of the assessed postoperative symptoms. Multivariate analysis found that patients with absent contractility had worse preoperative dysphagia (adjusted mean difference 1.09, p = 0.048), but postoperatively there were no significant differences in dysphagia scores at 5- and 10-year follow-up. No differences in overall patient satisfaction were identified across the follow-up period.

CONCLUSION

Laparoscopic partial fundoplication in patients with absent esophageal contractility achieves acceptable symptom control without significantly worse dysphagia compared with patients with normal contractility. Patients with absent contractility should still be considered for surgery.

Randomized Trial of Laparoscopic Nissen vs. Anterior 180 Degree Partial Fundoplication - Late Clinical Outcomes at 15-20 years

OBJECTIVE

To determine very late clinical outcomes at up to 20 years follow-up from a randomized controlled trial of Nissen vs. anterior 180-degree partial fundoplication.

SUMMARY BACKGROUND DATA

Nissen fundoplication for gastroesophageal reflux can be followed by troublesome side effects. To address this, partial fundoplications have been proposed. Previously reports from a randomized controlled trial of Nissen vs. anterior 180-degree partial fundoplication at up to 10 years follow-up showed good outcomes for both procedures.

METHODS

107 participants were randomized to Nissen vs. anterior 180-degree partial fundoplication. 15-20 year follow-up data was available for 79 (41 Nissen, 38 anterior). Outcome was assessed using a standardized questionnaire with 0-10 analogue scores and yes/no questions to determine reflux symptoms, side-effects and satisfaction with surgery.

RESULTS

After anterior fundoplication heartburn (mean score 3.2 vs 1.4, p = 0.001) and proton pump inhibitor use (41.7% vs 17.1%, p = 0.023) were higher, offset by less dysphagia for solids (mean score 1.8 vs 3.3, p = 0.015), and better ability to belch (84.2% vs 65.9%, p = 0.030). Measures of overall outcome were similar for both groups (mean satisfaction score 8.4 vs 8.0, p = 0.444; 86.8% vs 90.2% satisfied with outcome). Six participants underwent revision following anterior fundoplication (Nissen conversion for reflux - 6), and 7 underwent revision following Nissen fundoplication (Nissen to partial fundoplication for dysphagia - 5; redo Nissen for reflux - 1; paraesophageal hernia -1).

CONCLUSIONS

At 15-20 years follow-up Nissen and anterior 180-degree partial fundoplication achieved similar success, but with trade-offs between better reflux control vs. more side-effects after Nissen fundoplication.

Patients with ineffective esophageal motility benefit from laparoscopic antireflux surgery

BACKGROUND

Gastroesophageal reflux disease (GERD) is a common chronic disorder of the gastrointestinal tract, affecting more than 50% of Americans. The development of GERD may be associated with ineffective esophageal motility (IEM). The impact of esophageal motility on outcomes post laparoscopic antireflux surgery (LARS), including quality of life (QOL), remains to be defined. The purpose of this study is to analyze and compare QOL outcomes following LARS among patients with and without ineffective esophageal motility (IEM).

METHODS

This is a single-institution, retrospective review of a prospectively maintained database of patients who underwent LARS, from January 2012 to July 2019, for treatment of GERD at our institution. Patients undergoing revisional surgery were excluded. Patients with normal peristalsis (non-IEM) were distinguished from those with IEM, defined using the Chicago classification, on manometric studies. Four validated QOL surveys were used to assess outcomes: Reflux Symptom Index (RSI), Gastroesophageal Reflux Disease Health-Related QOL (GERD-HRQL), Laryngopharyngeal Reflux Health-Related QOL (LPR-HRQL), and Swallowing Disorders (SWAL) survey.

RESULTS

203 patients with complete manometric data were identified (75.4% female) and divided into two groups, IEM (n = 44) and non-IEM (n = 159). IEM and Non-IEM groups were parallel in age (58.1 ± 15.3 vs. 62.2 ± 12 years, p = 0.062), body mass index (27.4 ± 4.1 vs. 28.2 ± 4.9 kg/m², p = 0.288), distribution of comorbid disease, sex, and ASA scores. The groups differed in manometry findings and Johnson-DeMeester score (IEM: 38.6 vs. Non-IEM: 24.0, p = 0.023). Patients in both groups underwent similar rates of Nissen fundoplication (IEM: 84.1% vs. Non-IEM: 93.7%, p = 0.061) with greater improvements in dysphagia (IEM: 27.4% vs. 44.2%) in Non-IEM group but comparable benefit in reflux reduction (IEM: 80.6% vs. 72.4%) in both groups at follow-up. There were no differences in postoperative outcomes. Satisfaction rates with LARS were similar between groups (IEM: 80% vs. non-IEM: 77.9%, p > 0.05).

CONCLUSION

Patients with ineffective esophageal motility derive significant benefits in perioperative and QOL outcomes after LARS. Nevertheless, as anticipated, their baseline dysmotility may reduce the degree of improvement in dysphagia rates post-surgery compared to patients with normal motility. Furthermore, the presence of preoperative IEM should not be a contraindication for complete fundoplication. Key to optimal outcomes after LARS is careful patient selection based on objective perioperative data, including manometry evaluation, with the purpose of tailoring surgery to provide effective reflux control and improved esophageal clearance.

Assessing the efficacy and safety of laparoscopic antireflux procedures for the management of gastroesophageal reflux disease: a systematic review with network meta-analysis

BACKGROUND

Despite the extensive literature on laparoscopic antireflux surgery, comparative evidence across different procedures is scarce. The aim of this study was to assess and rank the most efficacious and safe laparoscopic procedures for the management of gastroesophageal reflux disease.

METHODS

Medline, Embase, AMED, CINAHL, CENTRAL, and OpenGrey databases were queried for randomized trials comparing two or more laparoscopic antireflux procedures with each other or with medical treatment for the management of gastroesophageal reflux disease. Pairwise meta-analyses were conducted for each pair of interventions using a random-effects model. Network meta-analysis was employed to assess the relative efficacy and safety of laparoscopic antireflux procedures for the management of gastroesophageal reflux disease.

RESULTS

Forty-four publications reporting 29 randomized trials which included 1892 patients were identified. The network of treatments was sparse with only a closed loop between different types of wraps; 270°, 360°, anterior 180° and anterior 90°; and star network between 360° and other treatments; and between anterior 180° and other treatments. Laparoscopic 270° (odds ratio, OR 1.19, 95% confidence interval, CI 0.64-2.22), anterior 180°, and anterior 90° were equally effective as 360° for control of heartburn, although this finding was supported by low quality of evidence according to GRADE modification for NMA. The odds for dysphagia were lower after 270° (OR 0.38, 95%, CI 0.24-0.60), anterior 90° (moderate quality evidence), and anterior 180° (low-quality evidence) compared to 360°. The odds for gas-bloat were lower after 270° (OR 0.51, 95% CI 0.27, 0.95) and after anterior 90° compared to 360° (low-quality evidence). Regurgitation, morbidity, and reoperation were similar across treatments, albeit these were associated with very low-quality evidence.

CONCLUSION

Laparoscopic 270° fundoplication achieves a better outcome than 360° total fundoplication, especially in terms of postoperative dysphagia, although other types of partial fundoplication might be equally effective.

Robotic approach for Collis gastroplasty

The true short esophagus is an entity of controversy among surgeons. Studies have been published about its diagnosis and laparoscopic treatment, without existing to date, publication of the treatment with robotic approach. We present, as a case report, our experience in robotic surgery for hiatal hernia with true short esophagus treated with Collis gastroplasty and Toupet fundoplication. Robotic surgery on the true short esophagus can facilitate mediastinal dissection and allow a more accurate suture technique. Studies are needed to compare the long-term results of this surgical technique between the conventional laparoscopic approach and the robotic approach.

Hiatal Hernia Presenting with Recurrent Non-ST Elevation Myocardial Infarction and Cardiac Tamponade

Hiatal hernia is a common pathology, particularly among the elderly or obese populations. Occasionally, markedly dilated hernias can impinge on surrounding structures, notably the heart or lung. In such cases, morbidity can be considerable. We present a case of an enlarging hiatal hernia that compressed the heart, leading to recurrent non-ST elevation myocardial infarction with cardiac tamponade. The patient was successfully managed with nasogastric decompression and surgical repair. We recommend that extrapericardial pathology be considered in tamponade patients with concurrent hiatal hernia and that surgery should be considered the definitive treatment modality.

Laparoscopic gastric fundus tamponade: a novel adaptation of the Toupet fundoplication for large paraesophageal hernia repair

BACKGROUND

Laparoscopic repair of large paraesophageal hiatal hernia with defects too large to close primarily or greater than 8 cm is technically challenging. The ideal repair remains unclear and is often debated. Utilizing the gastric fundus as an autologous patch to obliterate and tamponade large hiatal defects may offer a new solution. The aim of this study was to evaluate the short-term outcomes following partial posterior fundoplication with gastric fundus tamponade.

METHODS

Retrospective chart review and prospective patient follow up was conducted on patients who underwent laparoscopic hiatal hernia repair between 2015 and 2019 by a single surgeon. Basic demographics, pre-operative diagnoses, operative technique, and clinical outcomes were recorded.

RESULTS

Fifteen patients underwent the described technique for repair of large paraesophageal hiatal hernia. All procedures were completed laparoscopically with a short post-operative length of stay (mean of 3 days) and no 30-day readmissions. The majority of patients reported resolution of their pre-operative symptoms. Only one patient required surgery for emergent indications and the same patient was the only mortality in the study, which was secondary to respiratory failure, necrotizing pneumonia, and sepsis as a result of gastric volvulus and obstruction.

CONCLUSION

Utilizing the gastric fundus as an autologous patch to repair large hiatal hernia may be a safe and efficacious solution with good short-term outcomes. However, further studies should be conducted to elucidate long-term results.

Comparison of laparoscopic Toupet and laparoscopic Nissen fundoplications in neurologically normal children

INTRODUCTION

We compared laparoscopic Toupet fundoplication (LTF) and laparoscopic Nissen fundoplication (LNF) in neurologically normal children.

METHODS

Forty neurologically normal children who were followed up for more than 3 years after LTF (n = 22) or LNF (n = 18) were reviewed retrospectively. LTF and LNF were performed between 2006 and 2012.

RESULTS

There were no significant differences in gender (LTF, 15 male and 7 female patients; LNF:, 12 male and 6 female patients), mean age at surgery (LTF vs LNF: 2.5 vs 2.3 years), mean weight at surgery (LTF vs LNF: 9.6 vs 8.9 kg), preoperative symptoms, preoperative pH monitoring (pH <4) (LTF vs LNF: 26.7% vs 21.8%), mean operative time (LTF vs LNF: 117 vs 126 min), postoperative recommencement of enteral feeding (LTF vs LNF: 3.7 vs 3.8 days), or duration of hospitalization (LTF vs LNF: 5.5 vs 6.3 days). Intraoperative complications were esophageal trauma (LTF; n = 1; 4.5%) and liver trauma (LNF; n = 1; 5.6%) (P = 0.70). Post-LTF complications were wrap stenosis (n = 1; 4.5%), and post-LNF complications were wrap stenosis (n = 1; 5.5%) and gastric outlet obstruction (n = 1; 5.5%) (P = 0.43); all were managed conservatively. No case required conversion to open repair. There was no recurrence after LTF, but there were three cases (16.7%) after LNF (P = 0.08). Reoperation was performed at 4, 11, and 13 months, respectively.

CONCLUSION

Despite LTF and LNF appearing to be equally effective, three LNF cases required reoperation.

[Quality of life of patients with complicated reflux-esophagitis followed antireflux surgery]

AIM

To analyze quality of life of patients with complicated reflux-esophagitis followed antireflux surgery.

MATERIAL AND METHODS

The trial enrolled 200 patients who underwent surgical treatment at the Burdenko Faculty Surgery Clinic of Sechenov First Moscow State Medical University for complicated reflux esophagitis from 2008 to 2015. Inclusion criteria were long-standing reflux esophagitis irresistible to conservative treatment, hiatal hernia with shortening of the esophagus and/or peptic stricture and/or Barrett's esophagus. Patients were divided into 2 groups according to the degree of esophagus shortening: group I - 98 patients with esophagus shortening degree I; group II - 102 patients with shortening grade II. Men/women ratio was 87(43.5%)/113(56.5%). Mean age was 56.0±13.9 years (16-83 years). We performed fundoplication in A.F. Chernousov modification in the first group and modified valvular gastroplication in the second group. All patients underwent survey within 6 months - 10 years after surgery to assess long-term outcomes. X-ray examination, upper GI endoscopy, standard laboratory tests were performed with pH-impedance and computed tomography if it was necessary. Quality of life was estimated by RAND SF-36 and GSRS (Gastrointestinal Symptom Rating Scale) questionnaires.

RESULTS

SF-36 questionnaire revealed postoperative changes of physical, psychological and social values and was able to compare them with those in general population. Postoperative overall health was significantly higher in both groups compared with preoperative level and comparable with general population. GSRS questionnaire have also revealed positive changes. Overall postoperative GSRS score was 1.6±0.5 and 1.6±0.6 points in groups I and II respectively that corresponds to minor concern after surgery.

Barrett’s esophagus in 2016: From pathophysiology to treatment

Esophageal complications caused by gastroesophageal reflux disease (GERD) include reflux esophagitis and Barrett’s esophagus (BE). BE is a premalignant condition with an increased risk of developing esophageal adenocarcinoma (EAC). The carcinogenic sequence may progress through several steps, from normal esophageal mucosa through BE to EAC. A recent advent of functional esophageal testing (particularly multichannel intraluminal impedance and pH monitoring) has helped to improve our knowledge about GERD pathophysiology, including its complications. Those findings (when properly confirmed) might help to predict BE neoplastic progression. Over the last few decades, the incidence of EAC has continued to rise in Western populations. However, only a minority of BE patients develop EAC, opening the debate regarding the cost-effectiveness of current screening/surveillance strategies. Thus, major efforts in clinical and research practice are focused on new methods for optimal risk assessment that can stratify BE patients at low or high risk of developing EAC, which should improve the cost effectiveness of screening/surveillance programs and consequently significantly affect health-care costs. Furthermore, the area of BE therapeutic management is rapidly evolving. Endoscopic eradication therapies have been shown to be effective, and new therapeutic options for BE and EAC have emerged. The aim of the present review article is to highlight the status of screening/surveillance programs and the current progress of BE therapy. Moreover, we discuss the recent introduction of novel esophageal pathophysiological exams that have improved the knowledge of the mechanisms linking GERD to BE.

Laparoscopic Toupet fundoplication for gastroesophageal reflux: a series of 131 neurologically impaired pediatric cases at a single children's hospital

PURPOSE

To present the medium to long-term outcome of the largest pediatric series of laparoscopic Toupet fundoplications (LTF) performed at a single institution.

PATIENTS AND METHODS

Subjects were 131 neurologically impaired children (81 M, 50 F) who underwent LTF between 2003 and 2013. Our LTF involves full dissection of the crus of the diaphragm to allow the intraabdominal esophagus to be mobilized at least 3-4 cm.

RESULTS

Preoperative mean fraction time for pH <4 was 14.6 %. Mean age at LTF was 6.7 years (3 months-18 years). Mean duration of follow-up was 5.7 years (range 1.2-12.1 years). One case required conversion to open surgery. Intra-operative complications were all injuries to the esophagus/gastric wall (n = 4; 3.0 %) including full-thickness perforation (n = 1; 0.8 %). Postoperative complications included pyloric stenosis (n = 4; 3.0 %), dysphagia (n = 1; 0.8 %), incisional hernia (n = 1; 0.8 %), hemorrhage requiring transfusion (n = 1; 0.8 %), recurrence (n = 3; 2.3 % at 11, 13, and 48 months, respectively), and gastrostomy site infection (n = 7; 5.3 %). Mean operative time decreased significantly with experience from 180.8 min for the first quarter of subjects to 150.6 (2nd quarter), 128.6 (3rd) and 109.2 min (4th).

CONCLUSIONS

Our LTF would appear to be safe for treating GERD in children because of reliable outcome and low recurrence.

A Meta-Analysis of Randomized Controlled Trials to Compare Long-Term Outcomes of Nissen and Toupet Fundoplication for Gastroesophageal Reflux Disease

Aim

In recent years, several studies with large sample sizes and recent follow-up data have been published comparing outcomes between laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication. It is now timely to be re-evaluated and synthesized long-term efficacy and adverse events of both total and partial posterior fundoplication.

Materials and Methods

Electronic searches for RCTs comparing the outcome after laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication were performed in the databases of MEDLINE, EMBASE, and the Cochrane Center Register of Controlled Trials. The data of evaluation in positive and adverse results of laparoscopic Nissen fundoplication and laparoscopic Nissen fundoplication were extracted and compared using meta-analysis.

Results

13 RCTs were ultimately identified involving 814 (52.05%) and 750 (47.95%) patients who underwent laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication, respectively. The operative time, perioperative complications, postoperative satisfaction, recurrence, and the rates of medication adoption or re-operation due to recurrence were not significantly different between two groups. The two types of fundoplication both reinforced the anti-reflux barrier and elevated the lower esophageal sphincter pressure. However, rates of adverse results involving dysphasia, gas-bloat syndrome, inability to belch and re-operation due to severe dysphasia were significantly higher after LNF. In the subgroup analysis of wrap length≤2cm, laparoscopic Nissen fundoplication was associated with a significantly higher incidence of postoperative dysphagia. However, in the subgroup wrap length>2cm, the difference was not statistically significant.

Conclusion

Laparoscopic Toupet fundoplication might be the better surgery approach for gastroesophageal reflux disease with a lower rate of postoperative adverse results and equal effectiveness as Laparoscopic Nissen fundoplication.

A prospective cross-sectional study of laparoscopic subtotal Lind fundoplication for gastro-oesophageal reflux disease--a durable and effective anti-reflux procedure

INTRODUCTION

Laparoscopic partial fundoplication for gastro-oesophageal reflux disease (GORD) is reported to have fewer side effects when compared to Nissen fundoplication, but doubts remain over its long term durability in controlling reflux. The aim of this study was to assess outcome of symptoms for all patients presenting with GORD undergoing routine laparoscopic subtotal Lind fundoplication.

MATERIALS & METHODS

All patients undergoing laparoscopic fundoplication between August, 1999 and November, 2007 performed by a single surgeon were included in the study. The anti-reflux procedure studied was laparoscopic Lind (300°) fundoplication with crural repair in all cases. Patients completed pre and post-operative questionnaires containing validated scoring systems for heartburn, gas bloat, dysphagia and overall patient satisfaction.

RESULTS

Over the 100-month period, 320 consecutive patients underwent laparoscopic subtotal Lind fundoplication. Of these, 256 (80%) replied to the questionnaire at a mean of 31 months (range 3-96 months) following surgery. 91.4% of respondents had an improvement in heartburn symptom score with a significant reduction in score from 7.74 preoperatively to 1.25 postoperatively (p<0.001). There was also a significant reduction of mean modified Visick score for reflux control (heartburn and regurgitation) from 3.49 preoperatively to 1.48 after surgery (p<0.001). In total, 22 patients developed recurrent reflux symptoms with half of these reporting their recurrence within two years following surgery. Because of this all were tested with post-operative pH testing, yet only one had a 24-h pH time outside the normal range. Overall patient satisfaction was high with a visual analogue score of 9 and 88% of the patients claimed they would have the operation again.

CONCLUSION

Laparoscopic Lind fundoplication demonstrates excellent reflux control when performed routinely for all patients presenting with GORD. This technique is both durable and efficacious in controlling reflux symptoms.

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.

[The Mexican consensus on gastroesophageal reflux disease. Part II]

OBJECTIVE

To update the themes of endoscopic and surgical treatment of Gastroesophageal Reflux Disease (GERD) from the Mexican Consensus published in 2002.

METHODS

Part I of the 2011 Consensus dealt with the general concepts, diagnosis, and medical treatment of this disease. Part II covers the topics of the endoscopic and surgical treatment of GERD. In this second part, an expert in endoscopy and an expert in GERD surgery, along with the three general coordinators of the consensus, carried out an extensive bibliographic review using the Embase, Cochrane, and Medline databases. Statements referring to the main aspects of endoscopic and surgical treatment of this disease were elaborated and submitted to specialists for their consideration and vote, utilizing the modified Delphi method. The statements were accepted into the consensus if the level of agreement was 67% or higher.

RESULTS

Twenty-five statements corresponding to the endoscopic and surgical treatment of GERD resulted from the voting process, and they are presented herein as Part II of the consensus. The majority of the statements had an average level of agreement approaching 90%.

CONCLUSION

Currently, endoscopic treatment of GERD should not be regarded as an option, given that the clinical results at 3 and 5 years have not demonstrated durability or sustained symptom remission. The surgical indications for GERD are well established; only those patients meeting the full criteria should be candidates and their surgery should be performed by experts.

A clinical comparison of laparoscopic Nissen and Toupet fundoplication for gastroesophageal reflux disease

AIM

To compare the advantages and disadvantages of laparoscopic Nissen and Toupet fundoplication in the treatment of gastroesophageal reflux disease (GERD) and their indications.

PATIENTS AND METHODS

From June 2001 to December 2011, 383 patients with GERD were randomized into two groups according to the last number in their hospitalization number. Overall, 215 patients underwent laparoscopic Nissen fundoplication, and 168 underwent laparoscopic Toupet fundoplication.

RESULTS

No conversions to laparotomy or deaths were observed, and the symptoms disappeared completely postoperatively in both groups. Average follow-up was 5.6 years. No recurrence of symptoms was observed in the Nissen group. Eighteen patients experienced recurrence of symptoms in the Toupet group and were administered acid-suppressing drugs. Esophageal manometry and acid reflux testing were performed 4 months postoperatively, with normal results in both groups. The cure rate of esophageal inflammation was 88.4% in the Nissen group and 67.7% in the Toupet group. Four days postoperatively, the incidences of dysphagia and abdominal distension were significantly higher in the Nissen group compared with the Toupet group (28.4% and 16.7%, respectively); the difference between the two groups significantly decreased 1 year postoperatively (1.5% and 0.8%, respectively).

CONCLUSIONS

In the short term, the incidence of dysphagia was significantly lower after Toupet fundoplication, but the difference decreased significantly with extension of the postoperative recovery period. For patients with moderate to severe GERD, the laparoscopic Nissen fundoplication may be optimal; for elderly patients or for patients with significantly reduced esophageal peristalsis detected in preoperative examinations, the laparoscopic Toupet fundoplication should be considered.

Influence of wrap length on the effectiveness of Nissen and Toupet fundoplications: 5-year results of prospective, randomized study

BACKGROUND

Long-term results in antireflux surgery may depend on fundoplication type and wrap length. We compared the outcome of two different wrap lengths among the patients undergoing partial or total fundoplications. This study is the next part of a prospective 5-year follow-up assessment.

METHODS

A total of 153 patients were randomized to Nissen or Toupet 1.5- or 3-cm wrap laparoscopic fundoplication. The primary endpoint--treatment failure rate was defined as a recurrent GERD or persistent dysphagia. Intensity of heartburn, dysphagia, gas-bloating, presence of esophagitis were assessed as a secondary outcome at 1-year and 5-year follow-up.

RESULTS

At 5-year follow-up, data were collected from 129 (85 %) patients. At 1-year follow-up, 17 (11 %) treatment failures were detected. At the end of the fifth year, the numbers reached 23 (15 %). The failures were more common in the 1.5-cm Toupet (25 %) and the 3-cm Nissen group (18.2 %). The significant difference in failure rates was found between 1.5-cm and 3-cm Toupet groups (P < 0.05). Dysphagia remained low during the follow-up in all of the groups. The prevalence of higher scores of heartburn after 5 years was detected in Nissen 1.5-cm group (20.8 %). The lowest scores were observed in Toupet 3-cm group. Bloating symptoms were more prevalent among Nissen and Toupet 3-cm group patients at 5-year follow-up. At the end of the fifth year, the prevalence of esophagitis was lower in Nissen 1.5-cm (19.3 %) and Toupet 3-cm (13.3 %) groups. The highest prevalence of esophagitis-32.4 %-was found in Toupet 1.5-cm group.

CONCLUSIONS

Nissen and Toupet fundoplication achieved sufficient control of reflux with success rate of 85 % at 5-year follow-up. There were no significant differences in the postoperative dysphagia, esophagitis, and bloating rates. However, the distribution of treatment failures leads us to conclude that 1.5-cm wrap length is insufficient in cases of posterior partial fundoplication.

A prospective nonrandomized comparison of laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication in Indian population using detailed objective and subjective criteria

BACKGROUND:

Laparoscopic Nissen fundoplication (LNF) is a commonly performed procedure for the treatment of gastro esophageal reflux disease (GERD) worldwide. However, unfavourable postoperative sequel, including gas bloat and dysphagia, has encouraged surgeons to perform alternative procedures such as laparoscopic Toupet fundoplication (LTF). This prospective nonrandomized study was designed to compare LNF with LTF in patients with GERD.

MATERIALS AND METHODS:

Hundred and ten patients symptomatic for GERD were included in the study after having received intensive acid suppression therapy for a minimum of 8 weeks. A 24-hour pH metry was done on all patients. Fifty patients having reflux on 24-hour pH metry were taken up for the surgery. Patients were further divided into group-A (LNF) and group-B (LTF).

RESULTS:

The median percentage time with esophageal pH < 4 decreased from 10.18% and 12.31% preoperatively to 0.85% and 1.94% postoperatively in LNF and LTF-groups, respectively. There was a significant and comparable increase in length of lower esophageal sphincter (LES), length of intraabdominal part of LES and LES pressure at respiratory inversion point in both the groups. In LNF-group, five patients had early dysphagia that improved afterwards. There were no significant postoperative complications.

CONCLUSION:

LNF and LTF are highly effective in the management of GERD with significant improvement in symptoms and objective parameters. LNF may be associated with significantly higher incidence of short onset transient dysphagia that improves with time. Patients in both the groups showed excellent symptom and objective control on 24-hour pH metry on short term follow-up.

Five-year efficacy of laparoscopic Nissen fundoplication versus anterior 180° partial fundoplication in the management of reflux esophagitis: A randomized controlled trial

AIM: To evaluate the long-term clinical outcome of laparoscopic Nissen fundoplication versus anterior 180° partial fundoplication in the management of reflux esophagitis.

METHODS: One hundred and seven patients with reflux esophagitis were enrolled and randomly allocated into two groups to undergo laparoscopic Nissen fundoplication (Nissen group) and laparoscopic anterior 180° partial fundoplication (partial fundoplication group). The patients were followed for 5 years after operation, and clinical data, such as the incidences of heartburn, dysphagia, bloating or flatulence, belching ability, and degree of satisfaction with the operation, were collected.

RESULTS: There were no statistical significances between the two groups for the incidence of heartburn symptom and consumption of PPI. Though the incidence of dysphagia was similar between the two groups, the severity of the symptom in the partial fundoplication group was much lower than that in the Nissen group. There is a higher incidence of epigastric bloating, difficulty of belching and flatulence in the Nissen group. The degree of overall satisfaction with the operation was similar between the two groups. Most patients were free of reflux symptoms during the 5-year follow-up period.

CONCLUSION: Laparoscopic anterior 180° partial fundoplication has good and durable anti-reflux effect and is associated with a lower incidence of post-operative complications compared to Nissen fundoplication, and can be employed as a routine procedure for treatment of gastroesophageal reflux disease.

Surgical treatment of gastroesophageal reflux disease: total or partial fundoplication? systematic review and meta-analysis

CONTEXT

Although the high incidence of gastroesophageal reflux disease (GERD) in the population, there is much controversy in this topic, especially in the surgical treatment. The decision to use of a total or partial fundoplication in the treatment of GERD is still a challenge to many surgeons because the few evidence found in the literature.

OBJECTIVE

To bring more clear evidence in the comparison between total and partial fundoplication.

DATA SOURCES

A systematic review of the literature and metaanalysis with randomized controlled trials accessed from MEDLINE, LILACS, Cochrane Controlled Trials Database was done. The outcomes remarked were: dysphagia, inability to belch, bloating, recurrence of acid reflux, heartburn and esophagitis. For data analysis the odds ratio was used with corresponding 95% confidence interval. Statistical heterogeneity in the results of the metaanalysis was assessed by calculating a test of heterogeneity. The software Review Manager 5 (Cochrane Collaboration) was utilized for the data gathered and the statistical analysis. Sensitive analysis was applied using only trials that included follow-up over 2 years.

RESULTS

Ten trials were included with 1003 patients: 502 to total fundoplication group and 501 to partial fundoplication group. The outcomes dysphagia and inability to belch had statistical significant difference (P = 0.00001) in favor of partial fundoplication. There was not statistical difference in outcomes related with treatment failure. There were no heterogeneity in the outcomes dysphagia and recurrence of the acid reflux.

CONCLUSION

The partial fundoplication has lower incidence of obstructive side effects.

Randomized clinical trial of laparoscopic anterior 180° partial versus 360° Nissen fundoplication: 5-year results

Anterior partial fundoplication (AF) has been popularized by a lower risk of mechanical side effects. The question then emerges whether anterior partial wrap has a similar antireflux effect with Nissen fundoplication (NF). We therefore conducted a randomized study to compare the long-term outcome of anterior fundoplication with NF. One hundred patients who enrolled in the trial from May 2003 to March 2005 were randomized to laparoscopic AF or laparoscopic NF. Endoscopy, pH monitoring, manometry, a detailed questionnaire, and a visual analog symptom score were completed preoperative at 6, 12, 24, and 60 months after surgical procedures. The postoperative adverse effects such as dysphagia and flatulence were compared between the two groups. Revision surgery or maintenance proton pump inhibitor therapy was defined as failure. Fifty procedures were performed in each group. The outcome at 5 years follow-up was determined for 96 patients (96%; 49 patients in the AF group and 47 in the NF group). Three patients (3%) died of unrelated causes during follow-up, and one patient changed address. Both fundoplications were found to provide good control of reflux-related symptoms in most of the patients. For 96 patients followed up more than 5 years, gastroesophageal reflux symptoms were well controlled in 81 patients (84.38%); the mean DeMeester scores in the AF group decreased from 106.89 ± 14.12 to 12.67 ± 3.14 and in the NF group from 109.51 ± 17.98 to 10.81 ± 2.65, and the esophagitis was ameliorated visibly. Moreover, there were significantly fewer patients in the AF group who complained of flatulence. Compared with NF, anterior 180° partial fundoplication is an effective treatment of gastroesophageal reflux and associates with fewer postoperative adverse effects.

Value of preoperative esophageal function studies before laparoscopic antireflux surgery

BACKGROUND

The value of esophageal manometry and ambulatory pH monitoring before laparoscopic antireflux surgery (LARS) has been questioned because tailoring the operation to the degree of hypomotility often is not required. This study evaluated a consecutive cohort of patients referred for esophageal function studies in preparation for LARS to determine the rates of findings that would alter surgical decisions.

METHODS

High-resolution manometry (HRM) was performed for each subject using a 21-lumen water-perfused system, and motor function was characterized. Gastroesophageal reflux disease (GERD) was evident from ambulatory pH monitoring if thresholds for acid exposure time and/or positive symptom association probability were passed.

RESULTS

Of 1,081 subjects (age, 48.4 ± 0.4 years; 56.7% female) undergoing preoperative HRM, 723 (66.9%) also had ambulatory pH testing performed. Lower esophageal sphincter (LES) hypotension (38.9%) and nonspecific spastic disorder (NSSD) of the esophageal body (36.1%) were common. Obstructive LES pathophysiology was noted in 2.5% (achalasia in 1%; incomplete LES relaxation in 1.5%), and significant esophageal body hypomotility in 4.5% (aperistalsis in 3.2%; severe hypomotility in 1.3%) of the subjects. Evidence of GERD was absent in 23.9% of the subjects. Spastic disorders were more frequent in the absence of GERD (43.9% vs. 23.1% with GERD; p < 0.0001), whereas hypomotility and normal patterns were more common with GERD.

CONCLUSIONS

Findings considered absolute or relative contraindications for standard 360º fundoplication are detected in 1 of 14 patients receiving preoperative HRM. Additionally, spastic findings associated with persistent postoperative symptoms are detected at esophageal function testing that could be used in preoperative counseling and candidate selection. Physiologic testing remains important in the preoperative evaluation of patients being considered for LARS.

A meta-analysis comparing laparoscopic partial versus Nissen fundoplication

BACKGROUND

For proven gastro-oesophageal reflux disease, partial fundoplication is considered as effective as Nissen, but with fewer side effects. The aim of this meta-analysis was to compare the effect of laparoscopic partial fundoplication (LPF) with laparoscopic Nissen fundoplication (LNF).

METHODS

Extensive medical literature searches of the PubMed, Medline and Embase databases were performed up to April 2010 for all randomized clinical trials that compared LPF versus LNF. The effect variables analysed were the incidence of post-operative dysphagia, heartburn, inability to belch, outcome or satisfaction and Visick score. Meta-analyses were carried out using odds ratios (ORs) with 95% confidence interval.

RESULTS

Thirteen randomized trials were considered suitable for the meta-analysis. A total of 1374 patients underwent LPF or LNF. There was a significant reduction of the incidence of post-operative dysphagia (OR = 0.44, P < 0.0001) and inability to belch (OR = 0.41, P < 0.005) for the LPF compared to that of the LNF group. Compared with LPF, LNF resulted in a significant reduction of the incidence of post-operative heartburn (OR = 1.94, P < 0.01). The outcome or satisfaction of patients and Visick I and II scores were comparable between the two groups.

CONCLUSION

Both LPF and LNF are effective for the treatment of proven gastro-oesophageal reflux disease. LPF enables a decreased post-operative dysphagia and gas-related side effects, while LNF is more successful in controlling reflux symptoms, particularly heartburn, than LPF. A balance should be found between anti-reflux and side effects.

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.

Meta-analysis of laparoscopic total (Nissen) versus posterior (Toupet) fundoplication for gastro-oesophageal reflux disease based on randomized clinical trials

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) is the standard procedure for surgical management of gastro-oesophageal reflux disease (GORD). Laparoscopic Toupet fundoplication (LTF) is reported to be as effective as LNF but to be associated with a lower incidence of post-operative dysphagia. This meta-analysis was performed to compare the two techniques with respect to reflux control and associated complications, particularly dysphagia.

METHODS

Pubmed, Medline, Embase and The Cochrane Library were searched. Only randomized controlled trials (RCTs) comparing LNF and LTF were included. Outcomes evaluated were occurrences of heartburn and associated complications (e.g. dysphagia) and degree of patient's satisfaction at early (three to six months) and later (one to three years) post-operative periods.

RESULTS

Of 939 patients in seven RCTs, 478 received LNF and 461 received LTF. For both groups, control of reflux was good and occurrence of heartburn were similar. A lower incidence of post-operative dysphagia for both early and later post-operative periods was observed for the LTF group. Patient's satisfaction following either procedure was similar.

CONCLUSION

LNF and LTF are both safe and effective. LTF is truly associated with a lower occurrence of dysphagia. However, LTF is more likely than LNF to be associated with early surgical complications. On the whole, post-surgical satisfaction ratios for the two groups were comparable.

Systematic review and meta-analysis of laparoscopic Nissen (posterior total) versus Toupet (posterior partial) fundoplication for gastro-oesophageal reflux disease

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) is currently considered the surgical approach of choice for gastro-oesophageal reflux disease (GORD). Laparoscopic Toupet fundoplication (LTF) has been said to reduce troublesome dysphagia and gas-related symptoms. A systematic review and meta-analysis of randomized clinical trials (RCTs) was performed to compare LNF and LTF.

METHODS

Four electronic databases (MEDLINE, Embase, Cochrane Library and ISI Web of Knowledge CPCI-S) were searched and the methodological quality of included trials was evaluated. Outcomes included recurrent pathological acid exposure, oesophagitis, dysphagia, dilatation for dysphagia and reoperation rate. Results were pooled in meta-analyses as risk ratios (RRs) and weighted mean differences.

RESULTS

Seven eligible RCTs comparing LNF (n = 404) with LTF (n = 388) were identified. LNF was associated with a significantly higher prevalence of postoperative dysphagia (RR 1.61 (95 per cent confidence interval 1.06 to 2.44); P = 0.02) and dilatation for dysphagia (RR 2.45 (1.06 to 5.68); P = 0.04). There were more surgical reinterventions after LNF (RR 2.19 (1.09 to 4.40); P = 0.03), but no differences regarding recurrent pathological acid exposure (RR 1.26 (0.82 to 1.95); P = 0.29), oesophagitis (RR 1.20 (0.78 to 1.85); P = 0.40), subjective reflux recurrence, patient satisfaction, operating time or in-hospital complications. Inability to belch (RR 2.04 (1.19 to 3.49); P = 0.009) and gas bloating (RR 1.58 (1.21 to 2.05); P < 0.001) were more prevalent after LNF.

CONCLUSION

LTF reduces postoperative dysphagia and dilatation for dysphagia compared with LNF. Reoperation rate and prevalence of gas-related symptoms were lower after LTF, with similar reflux control. These results provide level 1a support for the use of LTF as the posterior fundoplication of choice for GORD.

Evidence-based appraisal in laparoscopic Nissen and Toupet fundoplications for gastroesophageal reflux disease

AIM: To demonstrate the optimal surgical procedure for gastroesophageal reflux disease.

METHODS: The electronic databases of Medline, Elsevier, Springerlink and Embase over the last 16 years were searched. All clinical trials involved in the outcomes of laparoscopic Nissen fundoplication (LNF) and laparoscopic Toupet fundoplication (LTF) were identified. The data of assessment in benefits and adverse results of LNF and LTF were extracted and compared using meta-analysis.

RESULTS: We ultimately identified a total of 32 references reporting nine randomized controlled trials, eight prospective cohort trials and 15 retrospective trials. These studies reported a total of 6236 patients, of whom 4252 (68.18%) underwent LNF and 1984 (31.82%) underwent LTF. There were no differences between LNF and LTF in patients’ satisfaction, perioperative complications, postoperative heartburn, reflux recurrence and re-operation. Both LNF and LTF enhanced the function of lower esophageal sphincter and improved esophagitis. The postoperative dysphagia, gas-bloating syndrome, inability to belch and the need for dilatation after LNF were more common than after LTF. Subgroup analyses showed that dysphagia after LNF and LTF was similar in patients with normal esophageal peristalsis (EP), but occurred more frequently in patients with weak EP after LNF than after LTF. Furthermore, patients with normal EP after LNF still had a higher risk of developing dysphagia than did patients with abnormal EP after LTF.

CONCLUSION: Compared with LNF, LTF offers equivalent symptom relief and reduces adverse results.

Endoscopic and laparoscopic treatment of gastroesophageal reflux

Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.
