Causes of dissatisfaction after laparoscopic fundoplication: the impact of new symptoms, recurrent symptoms, and the patient experience

A retrospective study assessing RefluxStop surgery for gastroesophageal reflux disease: Clinical outcomes in 79 patients from Germany

Background

This study reports outcomes of the RefluxStop procedure treating gastroesophageal reflux disease (GERD) in clinical practice at a high-volume regional hospital in Germany.

Methods

A retrospective analysis was conducted on 79 patients with chronic GERD that underwent the RefluxStop procedure, comprising high mediastinal dissection, loose cruroplasty, esophagogastroplication between vagal trunks, and fundus invagination of the RefluxStop implant. The primary outcome was GERD Health-Related Quality-of-Life (GERD-HRQL) score and improvement from baseline. Secondary outcomes included proton pump inhibitor (PPI) use and intra- and postoperative complications, including dysphagia, esophageal dilatation, and reoperation.

Results

Baseline characteristics (n = 79) included large hiatal hernia >3 cm (32.4 %) and previous antireflux surgery (20.3 %). At mean (SD) follow-up of 11 (4.4) months ranging from 4 to 19 months, the median (IQR) and mean (SD) improvements in GERD-HRQL score were 100 % (90.2-100 %) and 92.4 % (13.9 %) from baseline, respectively. Significant reduction in PPI use was observed from a baseline of 94.9 % to 2.5 % at follow-up. All cases of preoperative dysphagia (7.6 %) completely resolved. New-onset, mild dysphagia occurred in one subject (1.3 %) at final follow-up. One subject (1.3 %) experienced asymptomatic device migration into the stomach, likely due to surgical technique with a much too tight invagination, with subsequent conversion to Toupet fundoplication.

Conclusion

Analysis of this cohort that underwent RefluxStop surgery indicates excellent safety and effectiveness over this short-term follow-up. Significant improvements in quality of life and PPI use were observed in a population where half had either large hiatal hernia >3 cm or reoperation for previously failed antireflux surgery, a demographic with usually much higher complication rates.

Determination of causes of post-operative dysphagia after anti-reflux surgery based on intra-operative planimetry

INTRODUCTION

Dysphagia after anti-reflux surgery (ARS) is one of the most common indications for re-operative anti-reflux surgery and a leading cause of patient dissatisfaction. Unfortunately, the factors affecting its development are poorly understood. We investigated the correlation between pre-operative manometric and the intra-operative impedance planimetry (EndoFLIP™) measurements and development of post-operative dysphagia.

METHODS

A review of patients who underwent index robotic ARS in our institution. Patients who underwent pre-operative manometry and intra-operative EndoFLIP™ were included in our study. Dysphagia was assessed pre-operatively and at 3-month after surgery.

RESULTS

Fifty-five patients (26.9%) reported post-operative dysphagia, and 34 (16.6%) reported new or worsening dysphagia. On pre-operative manometry, patients with post-operative dysphagia had a lower distal contractile integral [868.7 (IQR 402.2-1447) mmHg s cm vs 1207 (IQR 612.1-2111) mmHg s cm, p = 0.006) and lower esophageal sphincter (LES) pressure [14.7 IQR (8.9-23.6) mmHg vs 20.7 IQR (10.2-32.6) mmHg, p = 0.01] compared to those without post-operative dysphagia. They were also found to have higher pre-operative cross-sectional surface area (CSA) [83 IQR (44.5-112) mm2 vs 66 IQR (42-93) mm2, p = 0.02], and distensibility index (DI) [4.2 IQR (2.2-5.5) mm2/mmHg vs 2.9 IQR (1.6-4.6) mm2/mmHg, p = 0.003] compared to patients without post-operative dysphagia. Additionally, the decrease in CSA [- 34 (- 18.5, - 74.5) mm2 vs - 26.5 (- 10.5, - 53.7) mm2, p = 0.03] and DI [- 2.3 (- 1.2, - 3.7) mm2/mmHg vs - 1.6 (- 0.7, - 3.3) mm2/mmHg, p = 0.03] measurements were greater in patients with post-operative dysphagia.

CONCLUSION

Patients who developed dysphagia post-operatively had poorer pre-operative motility and a greater change in LES characteristics intra-operatively. This finding suggests the utility of pre-operative manometry and intra-operative EndoFLIP in identifying patients at risk of developing dysphagia post-operatively.

Treating acid reflux without compressing the food passageway: 4-year safety and clinical outcomes with the RefluxStop device in a prospective multicenter study

INTRODUCTION

RefluxStop is an implantable device for laparoscopic surgical treatment of gastroesophageal reflux disease (GERD) to restore and maintain lower esophageal sphincter and angle of His anatomy without encircling and putting pressure on the food passageway, thereby avoiding side effects such as dysphagia and bloating seen with traditional fundoplication. This study reports the clinical outcomes with RefluxStop at 4 years following implantation of the device.

METHODS

A prospective, single arm, multicenter clinical investigation analyzing safety and effectiveness of the RefluxStop device in 50 patients with chronic GERD.

RESULTS

Available data are presented for 44 patients at 4 years with the addition of three patients at 3 years carried forward. At 4 years, median GERD-HRQL score was 90% reduced compared to baseline. Two patients (2/44) used regular daily proton pump inhibitors (PPIs) despite subsequent 24-h pH monitoring off PPI therapy yielding normal results. There were no device-related adverse events (AEs), esophageal dilations, migrations, or explants during the entire study period. AEs reported between 1 and 4 years were as follows: one subject with heartburn and a pathologic pH result with device positioned too low at surgery; one subject with dysphagia, thus, 46/47 patients reported no dysphagia-related AEs between years 1 and 4. Two patients (2/47) were dissatisfied with treatment despite normal 24-h pH monitoring, of whom one had manometry-verified dysmotility at 6 months, indicating dissatisfaction for reasons other than acid reflux.

CONCLUSION

These results confirm the excellent and already published 1-year results as stable in the long-term, supporting the safety and effectiveness of the RefluxStop device in treating GERD for over 4 years. GERD-HRQL score, pH testing, and PPI usage indicate treatment success without dysphagia or gas-bloating and only minimal incidence of other AEs. This favorably low rate of AEs is likely attributable to RefluxStop's dynamic physiologic interaction and non-encircling nature.

A decade of experience with minimally invasive anti-reflux operations: robot vs. LESS

BACKGROUND

The increasing use of robotic systems for anti-reflux operations prompted this study to evaluate and compare the efficacy of robotic and Laparo-Endoscopic Single-Site (LESS) approaches.

METHODS

From 2012, 228 robotic fundoplication and 518 LESS fundoplication patients were prospectively followed, analyzing perioperative metrics. Data are presented as median (mean ± SD); significance at p ≤ 0.05.

RESULTS

Patients undergoing a robotic vs. LESS fundoplication were 67 (64 ± 13.7) vs. 61 (59 ± 15.1) years-old with BMIs of 25 (25 ± 3.2) vs. 26 (25 ± 3.9) kg/m2 (p = 0.001 and 1.00, respectively). 72% of patients who underwent the robotic approach had a previous abdominal operation(s) vs 44% who underwent the LESS approach (p = 0.0001). 38% vs. 8% had a re-operative fundoplication (p = 0.0001), 59% vs. 45% had a type IV hiatal hernia (p = 0.0004). Operative duration was 160 (176 ± 76.7) vs. 130 (135 ± 50.5) min (p = 0.0001). There were 0 (robotic) vs. 5 (LESS) conversions to a different approach (p = 0.33). 5 Patients vs. 3 patients experienced postoperative complications (p = 0.06), and length of stay (LOS) was 1 (2 ± 2.6) vs. 1 (1 ± 3.2) days (p = 0.0001). Patient symptomatic dysphagia preoperatively for the robotic vs. LESS approach was scored as 2 (2.4 ± 1.9) vs. 1 (1.9 ± 1.6). Postoperatively, symptomatic dysphagia was scored as 1 (1.5 ± 1.6) vs. 1 (1.7 ± 1.7). The change in these scores was - 1 (- 1 ± 2.2) vs. 0 (- 0.5 ± 2.2) (p = 0.004).

CONCLUSION

Despite longer operative times and LOS in older patients, the robotic approach is efficient in undertaking very difficult operations, including patients with type IV or recurrent hiatal hernias. Furthermore, preoperative anti-reflux operations were more likely to be undertaken with the robotic approach than the LESS approach. The patient's postoperative symptomatic dysphagia improved relatively more than after the LESS approach. The vast majority of patients who underwent the LESS approach enjoyed improved cosmesis, thus, making LESS a stronger candidate for more routine operations. Despite patient selection bias, the robotic and LESS approaches to anti-reflux operations are safe, efficacious, and should be situationally utilized.

Malpractice claims after antireflux surgery and paraesophageal hernia repair: a population-based analysis

BACKGROUND

The complication rate of modern antireflux surgery or paraesophageal hernia repair is unknown, and previous estimates have been extrapolated from institutional cohorts.

METHODS

A population-based retrospective cohort study of patient injury cases involving antireflux surgery and paraesophageal hernia repair from the Finnish National Patient Injury Centre (PIC) register between Jan 2010 and Dec 2020. Additionally, the baseline data of all the patients who underwent antireflux and paraesophageal hernia operations between Jan 2010 and Dec 2018 were collected from the Finnish national care register.

RESULTS

During the study period, 5734 operations were performed, and the mean age of the patients was 54.9 ± 14.7 years, with 59.3% (n = 3402) being women. Out of all operations, 341 (5.9%) were revision antireflux or paraesophageal hernia repair procedures. Antireflux surgery was the primary operation for 79.9% (n = 4384) of patients, and paraesophageal hernia repair was the primary operation for 20.1% (n = 1101) of patients. A total of 92.5% (5302) of all the operations were laparoscopic. From 2010 to 2020, 60 patient injury claims were identified, with half (50.0%) of the claims being related to paraesophageal hernia repair. One of the claims was made due to an injury that resulted in a patient's death (1.7%). The mean Comprehensive Complication Index scores were 35.9 (± 20.7) and 47.6 (± 20.8) (p = 0.033) for antireflux surgery and paraesophageal hernia repair, respectively. Eleven (18.3%) of the claims pertained to redo surgery.

CONCLUSIONS

The rate of antireflux surgery has diminished and the rate of paraesophageal hernia repair has risen in Finland during the era of minimally invasive surgery. Claims to the PIC remain rare, but claims regarding paraesophageal hernia repairs and redo surgery are overrepresented. Additionally, paraesophageal hernia repair is associated with more serious complications.

Robotic-assisted versus laparoscopic redo antireflux surgery in children: A cost-effectiveness study

INTRODUCTION

Robotic-assisted redo fundoplication has some advantages compared to the laparoscopic approach in adults, although to date there are no studies in children.

METHODS

A retrospective case-control study was performed among consecutive children who underwent redo antireflux surgery between 2004 and 2020, divided into two groups: LAF group (laparoscopic redo-fundoplication) and RAF group (robotic-assisted redo-fundoplication). Demographics, clinical, intraoperative, postoperative and economic data were compared.

RESULTS

A total of 24 patients were included (10 LAF group; 14 RAF group) without demographic or clinical differences. The RAF group presented lower intraoperative blood loss (52 ± 19 vs. 145 ± 69 mL; p < 0.021), shorter surgery time (135 ± 39 vs. 179 ± 68 min; p = 0.009) and shorter length of hospital stay (median 3 days [2-4] vs. 5 days [3-7]; p = 0.002). The RAF group presented a higher rate of symptom improvement (85.7% vs. 60%; p = 0.192) and lower overall associated economic costs (25 800$ vs. 45 500$; p = 0.012).

CONCLUSION

Robotic-assisted redo antireflux surgery may offer several benefits over the laparoscopic approach. Prospective studies are still needed.

Magnetic sphincter augmentation may limit access to magnetic resonance imaging

Magnetic sphincter augmentation (MSA) is an alternative surgical treatment for gastroesophageal reflux disease; however, >1.5 T magnetic resonance imaging (MRI) is contraindicated for patients who have undergone MSA with the LINX Reflux Management System (Torax Medical, Inc. Shoreview, Minnesota, USA). This drawback can impose a barrier to access of MRI, and cases of surgical removal of the device to enable patients to undergo MRI have been reported. To evaluate access to MRI for patients with an MSA device, we conducted a structured telephone interview with all diagnostic imaging providers in Arizona in 2022. In 2022, only 54 of 110 (49.1%) locations that provide MRI services had at least one 1.5 T or lower MRI scanner. The rapid replacement of 1.5 T MRI scanners by more advanced technology may limit healthcare options and create an access barrier for patients with an MSA device.

Robotic revision surgery after failed Nissen anti-reflux surgery: a single center experience and a literature review

BACKGROUND

The gastroesophageal reflux disease (GERD) worldwide prevalence is increasing maybe due to population aging and the obesity epidemic. Nissen fundoplication is the most common surgical procedure for GERD with a failure rate of approximately 20% which might require a redo surgery. The aim of this study was to evaluate the short- and long-term outcomes of robotic redo procedures after anti-reflux surgery failure including a narrative review.

METHODS

We reviewed our 15-year experience from 2005 to 2020 including 317 procedures, 306 for primary, and 11 for revisional surgery.

RESULTS

Patients included in the redo series underwent primary Nissen fundoplication with a mean age of 57.6 years (range, 43-71). All procedures were minimally invasive and no conversion to open surgery was registered. The meshes were used in five (45.45%) patients. The mean operative time was 147 min (range, 110-225) and the mean hospital stay was 3.2 days (range, 2-7). At a mean follow-up of 78 months (range, 18-192), one patient suffered for persistent dysphagia and one for delayed gastric emptying. We had two (18.19%) Clavien-Dindo grade IIIa complications, consisting of postoperative pneumothoraxes treated with chest drainage.

CONCLUSION

Redo anti-reflux surgery is indicated in selected patients and the robotic approach is safe when it is performed in specialized centers, considering its surgical technical difficulty.

Crural closure, not fundoplication, results in a significant decrease in lower esophageal sphincter distensibility

INTRODUCTION

The esophagogastric junction (EGJ) is a complex anti-reflux barrier whose integrity relies on both the intrinsic lower esophageal sphincter (LES) and extrinsic crural diaphragm. During hiatal hernia repair, it is unclear whether the crural closure or the fundoplication is more important to restore the anti-reflux barrier. The objective of this study is to analyze changes in LES minimum diameter (D_min) and distensibility index (DI) using the endoluminal functional lumen imaging probe (FLIP) during hiatal hernia repair.

METHODS

Following implementation of a standardized operative FLIP protocol, all data were collected prospectively and entered into a quality database. This data were reviewed retrospectively for all patients undergoing hiatal hernia repair. FLIP measurements were collected prior to hernia dissection, after hernia reduction, after cruroplasty, and after fundoplication. Additionally, subjective assessment of the tightness of crural closure was rated by the primary surgeon on a scale of 1 to 5, 1 being the loosest and 5 being the tightest.

RESULTS

Between August 2018 and February 2020, 97 hiatal hernia repairs were performed by a single surgeon. FLIP measurements collected using a 40-mL volume fill without pneumoperitoneum demonstrated a significant decrease in LES D_min (13.84 ± 2.59 to 10.27 ± 2.09) and DI (6.81 ± 3.03 to 2.85 ± 1.23 mm²/mmHg) after crural closure (both p < 0.0001). Following fundoplication, there was a small, but also statistically significant, increase in both D_min and DI (both p < 0.0001). Additionally, subjective assessment of crural tightness after cruroplasty correlated well with DI (r = - 0.466, p < 0.001) and all patients with a crural tightness rating ≥ 4.5 (N = 13) had a DI < 2.0 mm²/mmHg.

CONCLUSION

Cruroplasty results in a significant decrease in LES distensibility and may be more important than fundoplication in restoring EGJ competency. Additionally, subjective estimation of crural tightness correlates well with objective FLIP evaluation, suggesting surgeon assessment of cruroplasty is reliable.

Postoperative Dysphagia Following Esophagogastric Fundoplication: Does the Timing to First Dilation Matter?

BACKGROUND

Postoperative dysphagia after anti-reflux surgery typically resolves in a few weeks. However, even after the initial swelling has resolved at 6 weeks, dysphagia can persist in 30% of patients necessitating esophageal dilation. The purpose of this study was to investigate the effect of esophageal dilation on postoperative dysphagia, the recurrence of reflux symptoms, and the efficacy of pneumatic dilations on postoperative dysphagia.

METHODS

A prospectively collected database was reviewed for patients who underwent partial/complete fundoplication with/without paraesophageal hernia repair between 2006 and 2014. Patient age, sex, BMI, DeMeester score, procedure type, procedure duration, length of stay, postoperative dysphagia, time to first pneumatic dilation, number of dilations, and the need for reoperations were collected.

RESULTS

The study included 902 consecutive patients, 71.3% females, with a mean age of 57.8 ± 14.7 years. Postoperative dysphagia was noted in 26.3% of patients, of whom 89% had complete fundoplication (p < 0.01). Endoscopic dilation was performed in 93 patients (10.3%) with 59 (63.4%) demonstrating persistent dysphagia. Recurrent reflux symptoms occurred in 35 (37.6%) patients who underwent endoscopic dilation. Patients who underwent a dilation for symptoms of dysphagia were less likely to require a revisional surgery later than patients who had dysphagia but did not undergo a dilation before revisional surgery (17.2% vs 41.7%, respectively, p < 0.001) in the 4-year follow-up period. The duration of initial dilation from surgery was inversely related to the need for revisional surgery (p = 0.047), while more than one dilation was not associated with additive benefit.

CONCLUSION

One attempt at endoscopic dilation of the esophagogastric fundoplication may provide relief in patients with postoperative dysphagia and can be used as a predictive factor for the need of revision. However, there is an increased risk for recurrent reflux symptoms and revisional surgery may ultimately be indicated for control of symptoms.

Robotic Complex Fundoplication in Patients at High-Risk to Fail

Background:

This study was undertaken to analyze our outcomes after robotic fundoplication for GERD in patients with failed antireflux procedures, with type IV (i.e., giant) hiatal hernias, or after extensive intra-abdominal surgery with mesh, and to compare our results to outcomes predicted by the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) Surgical Risk Calculator and to national outcomes reported by NSQIP.

Methods:

100 patients undergoing robotic fundoplication for the aforementioned factors were prospectively followed.

Results:

100 patients, aged 67 (67 ± 10.3) years with body mass index (BMI) of 26 (25 ± 2.9) kg/m² underwent robotic fundoplication for failed antireflux fundoplications (43%), type IV hiatal hernias (31%), or after extensive intra-abdominal surgery with mesh (26%). Operative duration was 184 (196 ± 74.3) min with an estimated blood loss of 24 (51 ± 82.9) mL. Length of stay was 1 (2 ± 3.6) day. Two patients developed postoperative ileus. Two patients were readmitted within 30 days for nausea.

Nationally reported outcomes and those predicted by NSQIP were similar. When comparing our actual outcomes to predicted and national NSQIP outcomes, actual outcomes were superior for serious complications, any complications, pneumonia, surgical site infection, deep vein thrombosis, readmission, return to OR, and sepsis (P < 0.05); our actual outcomes were not worse for renal failure, deaths, cardiac complications, and discharge to a nursing facility.

Conclusions:

Our patients were not a selective group; rather they were more complex than reported in NSQIP. Most of our results after robotic fundoplication were superior to predicted and national outcomes. The utilization of the robotic platform for complex operations and fundoplications to treat patients with GERD is safe and efficacious.

Importance of esophageal pH monitoring and manometry in indicating surgical treatment of gastroesophageal reflux disease

OBJECTIVE

To demonstrate the need of performing esophageal pH monitoring and manometry in patients with clinical suspicion of Gastroesophageal reflux disease, as more accurate and practical complementary exams in the indication of surgical treatment.

METHODS

A systematic review was carried out in the PubMed/Medline database, based on the recommendations of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, selecting studies in humans, published in Portuguese, Spanish, and English, from January 1, 2009 to August 5, 2020. The following descriptors were used: "reflux gastroesophageal" AND "surgery" AND "surgical treatment" AND "esophageal manometry" OR "pH monitoring". After that, retrospective or prospective observational studies with a sample of less than 100 individuals, or with limited access, reports or case series, review articles, letters, comments, or book chapters were excluded. To facilitate the application of the exclusion criteria, the Rayyan management base was used.

RESULTS

Out of the 676 studies found, 19 valid and eligible studies were selected to make inferences.

CONCLUSIONS

Based on the best evidence, currently, considering national particularities, performing a 24-hour esophageal pH monitoring and esophageal manometry for all patients undergoing anti-reflux surgery.

Safety and efficacy of an implantable device for management of gastroesophageal reflux in lung transplant recipients

Background

Magnetic sphincter augmentation (MSA) is a promising minimally invasive surgical technique for management of gastroesophageal reflux disease (GERD); however, device implantation after transplantation has not been studied and may be concerning in these immunosuppressed patients. We explored the safety of the LINX Reflux Management System (MSA device) for management of GERD following lung transplantation (LTx).

Methods

Lung transplant recipients who underwent LINX implantation at our institution between 2017 and 2019 were followed prospectively in the Reflux Following Lung Transplantation and Associated Treatment Registry. Ambulatory pH testing and acid-suppressing medication use were compared before and after LINX implantation. One-year outcomes and change in pulmonary function were compared between matched LINX and fundoplication groups.

Results

Of 17 patients who underwent post-lung transplant LINX implantation, 8 (47.1%) agreed to undergo post-LINX pH testing. Three/eight (37.5%) patients achieved normal esophageal acid exposure time; 14 (82.4%) remained on acid-suppressing medication at one-year under the direction of their transplant teams. One-year patient survival and change in pulmonary function were similar between groups. LINX patients experienced more early side effects.

Conclusions

Use of the LINX MSA device in a cohort of lung transplant recipients at our institution was associated with similar short-term safety compared to traditional fundoplication, however assessment of efficacy was limited. Further investigation is needed to characterize the long-term efficacy of LINX implantation after LTx.

The prevalence of intestinal dysbiosis in patients referred for antireflux surgery

Background

Prior to antireflux surgery, most patients with symptoms of gastroesophageal reflux disease (GERD) have been taking long-term proton pump inhibitors (PPIs). PPIs have been shown to cause changes to the intestinal microbiota, such as small intestinal bacterial overgrowth (SIBO), which is characterised by symptoms of gas bloating. Patients undergoing antireflux surgery are not routinely screened for SIBO, yet many patients experience gas-related symptoms postoperatively.

Methods

Data from consecutive patients (n = 104) referred to a speciality reflux centre were retrospectively assessed. Patients underwent a routine diagnostic workup for GERD including history, endoscopy, oesophageal manometry and 24-h pH-impedance monitoring off PPIs. Intestinal dysbiosis was determined by hydrogen and methane breath testing with a hydrogen-positive result indicative of SIBO and a methane-positive result indicative of intestinal methanogen overgrowth (IMO).

Results

60.6% of patients had intestinal dysbiosis (39.4% had SIBO and 35.6% had IMO). Patients with dysbiosis were more likely to report bloating (74.6% vs 48.8%; P = 0.01) and belching (60.3% vs 34.1%; P = 0.01). The oesophageal acid exposure time and number of reflux episodes were similar between dysbiosis and non-dysbiosis groups, but patients with dysbiosis were more likely to have a positive reflux-symptom association (76.2% vs 31.7%; P < 0.001), especially for regurgitation in those with SIBO (P = 0.01). Hydrogen gas production was significantly greater in patients with a positive reflux-symptom association for regurgitation (228.8 ppm vs 129.1 ppm, P = 0.004) and belching (mean AUC 214.8 ppm vs 135.9 ppm, P = 0.02).

Conclusions

The prevalence of intestinal dysbiosis is high in patients with GERD, and these patients are more likely to report gas-related symptoms prior to antireflux surgery. Independently, SIBO may be a contributory factor to refractory reflux symptoms and gas bloating in antireflux surgery candidates.

ENDOSCOPIC EVALUATION OF POST-FUNDOPLICATION ANATOMY AND CORRELATION WITH SYMPTOMATOLOGY

Background:

Upper digestive endoscopy is important for the evaluation of patients submitted to fundoplication, especially to elucidate postoperative symptoms. However, endoscopic assessment of fundoplication anatomy and its complications is poorly standardized among endoscopists, which leads to inadequate agreement.

Aim:

To assess the frequency of postoperative abnormalities of fundoplication anatomy using a modified endoscopic classification and to correlate endoscopic findings with clinical symptoms.

Method:

This is a prospective observational study, conducted at a single center. Patients were submitted to a questionnaire for data collection. Endoscopic assessment of fundoplication was performed according to the classification in study, which considered four anatomical parameters including the gastroesophageal junction position in frontal view (above or at the level of the pressure zone); valve position at retroflex view (intra-abdominal or migrated); valve conformation (total, partial, disrupted or twisted) and paraesophageal hernia (present or absent).

Results:

One hundred patients submitted to fundoplication were evaluated, 51% male (mean age: 55.6 years). Forty-three percent reported postoperative symptoms. Endoscopic abnormalities of fundoplication anatomy were reported in 46% of patients. Gastroesophageal junction above the pressure zone (slipped fundoplication), and migrated fundoplication, were significantly correlated with the occurrence of postoperative symptoms. There was no correlation between symptoms and conformation of the fundoplication (total, partial or twisted).

Conclusion:

This modified endoscopic classification proposal of fundoplication anatomy is reproducible and seems to correlate with symptomatology. The most frequent abnormalities observed were slipped and migrated fundoplication, and both correlated with the presence of symptoms.

Mind the Gap: Current Treatment Alternatives for GERD Patients Failing Medical Treatment and Not Ready for a Fundoplication

BACKGROUND

Gastroesophageal reflux disease is associated with Barrett esophagus, esophageal adenocarcinoma, and significantly impacts quality of life. Medical management is the first line therapy with surgical fundoplication as an alternative therapy. However, a small portion of patients who fail medical therapy are referred for surgical consultation. This creates a "gap" in therapy for those patients dissatisfied with medical therapy but are not getting referred for surgical consultation. Three procedures have been designed to address these patients. These include radiofrequency ablation (RFA) of the lower esophageal sphincter, transoral incisionless fundoplication (TIF), and magnetic sphincter augmentation.

MATERIALS AND METHODS

A Pubmed literature review was conducted of all publications for RFA, TIF, and MSA. Four most common endpoints for the 3 procedures were compared at different intervals of follow-up. These include percent of patients off proton pump inhibitors (PPIs), GERD-HRQL score, DeMeester score, and percent of time with pH <4. A second query was performed for patients treated with PPI and fundoplications to match the same 4 endpoints as a control.

RESULTS

Variable freedom from PPI was reported at 1 year for RFA with a weighted mean of 62%, TIF with a weighted mean of 61%, MSA with a weighted mean of 85%, and fundoplications with a weighted mean of 84%. All procedures including PPIs improved quality-of-life scores but were not equal. Fundoplication had the best improvement followed by MSA, TIF, RFA, and PPI, respectively. DeMeester scores are variable after all procedures and PPIs. All MSA studies showed normalization of pH, whereas only 4 of 17 RFA studies and 3 of 11 TIF studies reported normalization of pH.

CONCLUSIONS

Our literature review compares 3 rival procedures to treat "gap" patients for gastroesophageal reflux disease with 4 common endpoints. Magnetic sphincter augmentation appears to have the most reproducible and linear outcomes but is the most invasive of the 3 procedures. MSA outcomes most closely mirrors that of fundoplication.

Postoperative Gastrointestinal Complaints After Laparoscopic Nissen Fundoplication

PURPOSE

To investigate the postoperative gastrointestinal complaints and their effects on the satisfaction level of patients after laparoscopic Nissen fundoplication (LNF).

MATERIALS AND METHODS

Over a 7-year period, 553 patients who underwent "floppy" LNF were evaluated for preoperative and postoperative complaints. For this purpose, a set of questions derived from gastroesophageal reflux disease-health-related quality-of-life questionnaire (GERD-HRQL) was used. A P-value of <0.05 was considered to show a statistically significant result.

RESULTS

The present study included 215 patients with a mean follow-up of 60 months. Reflux-related symptoms [regurgitation (17.7%), heartburn (17.2%), and vomiting (3.7%)] and nonspecific symptoms [bloating (50.2%), abdominal pain (15.3%), and belching (27%)] showed a significant decrease (P<0.001) after the surgery. Inability to belch (25.1%) and early satiety (29.3%) were the newly emerged symptoms. The percentage of patients with flatulence increased from 23.3% to 38.1% after LNF. There was no significant difference for dysphagia (25.6%) and diarrhea (15.3%) in the postoperative period. Of the patients, 15.3% had recurrent preoperative complaints and 9.8% were using drugs for that condition. Satisfaction level and preference for surgery were 82.8% and 91.6%, respectively. There was no significant difference in GERD-HRQL score according to body mass index.

CONCLUSIONS

This is the first study in which postoperative reflux-related and nonspecific gastrointestinal complaints are analyzed together for a long follow-up period. We found a significant decrease in many reflux-related and nonspecific symptoms. Although some disturbing complaints like inability to belch, early satiety, and flatulence emerged, the preference for surgery did not change.

Feasibility and outcomes of anti-reflux mucosectomy for proton pump inhibitor dependent gastroesophageal reflux disease: First Indian study (with video)

BACKGROUND

Anti-reflux mucosectomy (ARMS) is a newfangled minimally invasive technique, with successful outcomes for the management of gastroesophageal reflux (GER). We present our initial experience (success rate) and safety profile for this procedure.

METHODS

Consecutive patients with daily dependence on proton pump inhibitor (PPI) for GER were prospectively enrolled from September 2016 to August 2019 and underwent ARMS using a cap assisted endoscopic mucosal resection. Severity was assessed by gastroesophageal reflux disease questionnaire. Gastroscopy and 24-h pH-metry was done pre and post procedure. Patient characteristics, PPI requirement, adverse events and follow-up were documented.

RESULTS

Sixty-two patients [44 (71%) male] underwent successful ARMS with a mean age (SD) of 36 (9.9) years. Technical success was achieved in 100 % of patients. Intraoperative bleeding was noted in 62 (100%) patients, endoscopic hemostasis was successfully achieved. At follow-up dysphagia was seen in 5 (8%) patients which needed a single session of endoscopic dilation. At 2 months, mean (SD) DeMeester score normalized in 45 (72.5%) patients from 76.8 (18.3) to 14.3 (6.1) (P < 0.001). PPI could be stopped in 43 (69.4%) patients. The mean (SD) GERD-Q score reduced from 10.6 (1.9) to 3.4 (1.5) (P < 0.001). However, in 12 (19.3%) patients low dose of PPIs was continued, while 7 (11.3%) patients continued full dose. Thirty-eight (61.3%) patients telephonically reported symptomatic improvement and were off PPIs at 12 months.

CONCLUSIONS

Anti-reflux mucosectomy is safe and effective for treatment of GER. The long term outcomes are favorable, response is durable and promising at our center. Appropriate patient selection still remains primal to the overall success of ARMS.

Long-term patient satisfaction and durability of laparoscopic anti-reflux surgery in a large Danish cohort: study protocol for a retrospective cohort study with development of a novel scoring system for patient selection

INTRODUCTION

Laparoscopic anti-reflux surgery is standard of care in surgical treatment of gastro-oesophageal reflux disease and is not without risks of adverse effects, including disruption of the fundoplication and postfundoplication dysphagia, in some cases leading to reoperation. Non-surgical factors such as pre-existing anxiety or depression influence postoperative satisfaction and symptom relief. Previous studies have focused on a short-term follow-up or only certain aspects of disease, such as reoperation or postoperative quality of life. The aim of this study is to evaluate long-term patient-satisfaction and durability of laparoscopic anti-reflux surgery in a large Danish cohort using a comprehensive multimodal follow-up, and to develop a clinically applicable scoring system usable in selecting patients for anti-reflux surgery.

METHODS AND ANALYSIS

The study is a retrospective cohort study utilising data from patient records and follow-up with patient-reported quality of life as well as registry-based data. The study population consists of all adult patients having undergone laparoscopic anti-reflux surgery at The Department of Surgery, Kolding Hospital, a part of Lillebaelt Hospital Denmark in an 11-year period. From electronic records; patient characteristics, preoperative endoscopic findings, reflux disease characteristics and details on type of surgery, will be identified. Disease-specific quality of life and dysphagia will be collected from a patient-reported follow-up. From Danish national registries, data on comorbidity, reoperative surgery, use of pharmacological anti-reflux treatment, mortality and socioeconomic factors will be included. Primary outcome of this study is treatment success at follow-up.

ETHICS AND DISSEMINATION

Study approval has been obtained from The Danish Patient Safety Agency, The Danish Health Data Authority and Statistics Denmark, complying to Danish and EU legislation. Inclusion in the study will require informed consent from participating subjects. The results of the study will be published in peer-reviewed medical journals regardless of whether these are positive, negative or inconclusive.

Asymmetrical elevation of esophagogastric junction pressure suggests hiatal repair contributes to antireflux surgery dysphagia

The radial distribution of esophago-gastric junction (EGJ) pressures with regard to troublesome dysphagia (TDysph) after antireflux surgery is poorly understood. Before and after antireflux surgery, end-expiratory and peak-inspiratory EGJ pressures were measured at eight angles of 45° radial separation in patients with reflux disease. All 34 patients underwent posterior crural repair, then either 90° anterior (N = 13) or 360° fundoplication (N = 21). Dysphagia was assessed prospectively using a validated questionnaire (score range 0-45) and TDysph defined as a dysphagia score that was ≥5 above pre-op baseline. Compared with before surgery, for 90° fundoplication, end-expiratory EGJ pressures were highest in the left-anterolateral sectors, the position of the partial fundoplication. In other sectors, pressures were uniformly elevated. Compared with 90° fundoplication, radial pressures after 360° fundoplication were higher circumferentially (P = 0.004), with a posterior peak. Nine patients developed TDysph after surgery with a greater increase in end-expiratory and peak-inspiratory EGJ pressures (P = 0.03 and 0.03, respectively) and significantly higher inspiratory pressure at the point of maximal radial pressure asymmetry (P = 0.048), compared with 25 patients without TDysph. Circumferential elevation of end-expiratory EGJ pressure after 90° and 360° fundoplication suggests hiatal repair elevates EGJ pressure by extrinsic compression. The highly localized focal point of elevated EGJ pressure upon inspiration in patients with TDysph after surgery is indicative of a restrictive diaphragmatic hiatus in the presence of a fundoplication.

Laparoendoscopic Single-Site (LESS) versus Robotic “Redo” Hiatal Hernia Repair with Fundoplication: Which Approach is Better?

Only a small percentage of patients fail laparoscopic fundoplications undertaken for gastroesophageal reflux disease. But because many laparoscopic fundoplications have been undertaken, surgeons frequently encounter patients in need of “redo” operations. This study was undertaken to evaluate the robotic approach versus laparoendoscopic single-site (LESS) approach for redo fundoplications. With an Institutional Review Board approval, 64 patients undergoing LESS (n = 32) or robotic (n = 32) redo antireflux operations were prospectively followed up. Data are presented as median (mean + SD). For LESS versus robotic redo operations, the operative duration was 145 (143 ± 33.5) versus 196 (208 ± 76.7) minutes ( P < 0.01), estimated blood loss was 50 (80 ± 92.1) versus 20 (43 ± 57.1) mL ( P = 0.07), and length of stay was 1 (3 ± 5.4) versus 1 (2 ± 1.9) day ( P = 0.57); 1 LESS operation was converted to “open.” Operative duration was longer for men ( P = 0.01). Postoperative complications were not more frequent after Nissen (n = 36) or Toupet (n = 28) fundoplication, regardless of the approach. When matched by BMI, operative duration was prolonged by a large Type I to IV hiatal hernia ( P = 0.01). Symptoms improved dramatically and were similar with both approaches, and patient satisfaction was high. Robotic redo antireflux operations take longer than LESS operations. LESS and robotic redo antireflux operations are both safe and offer significant and similar amelioration of symptoms after failed fundoplications.

Acceptable outcomes after fundoplication-different views are held by patients, GPs, and surgeons

Antireflux surgery aims to improve quality of life. However, whether patients and clinicians agree on what this means, and what is an acceptable outcome following fundoplication, is unknown. This study used clinical scenarios pertinent to laparoscopic fundoplication for gastroesophageal reflux to define acceptable outcomes from the perspective of patients, surgeons, and general practitioners (GPs). Patients who had previously undergone a laparoscopic fundoplication, general practitioners, and esophagogastric surgeons were invited to rank 11 clinical scenarios of outcomes following laparoscopic fundoplication for acceptability. Clinicopathological and practice variables were collated for patients and clinicians, respectively. GPs and esophagogastric surgeons additionally were asked to estimate postfundoplication outcome probabilities. Descriptive and multivariate statistical analyses were undertaken to examine for associations with acceptability. Reponses were received from 331 patients (36.4% response rate), 93 GPs (13.4% response), and 60 surgeons (36.4% response). Bloating and inability to belch was less acceptable and dysphagia requiring intervention more acceptable to patients compared to clinicians. On regression analysis, female patients found bloating to be less acceptable (OR: 0.51 [95%CI: 0.29-0.91]; P = 0.022), but dysphagia more acceptable (OR: 1.93 [95%CI: 1.17-3.21]; P = 0.011). Postfundoplication estimation of reflux resolution was higher and that of bloating was lower for GPs compared to esophagogastric surgeons. Patients and clinicians have different appreciations of an acceptable outcome following antireflux surgery. Female patients are more concerned about wind-related side effects than male patients. The opposite holds true for dysphagia. Surgeons and GPs differ in their estimation of event probability for patient recovery following antireflux surgery, and this might explain their differing considerations of acceptable outcomes.

Endoscopic magnet placement into subadventitial tunnels for augmenting the lower esophageal sphincter using submucosal endoscopy: ex vivo and in vivo study in a porcine model (with video)

BACKGROUND AND AIMS

Endolumenal therapies serve as a treatment option for GERD. This study aimed to determine if magnets could be placed endoscopically using the adventitial layer to create a subadventitial space near the esophagogastric junction to augment the lower esophageal sphincter using submucosal endoscopy.

METHODS

This study consisted of 2 phases, ex vivo and in vivo, with domestic pig esophagus. A long submucosal tunnel was made at the mid to lower esophagus. The muscularis propria was incised by a needle-knife within the submucosal tunnel. A subadventitial tunnel was made by biliary balloon catheter blunt dissection, and a magnet was deployed in the subadventitial space. The same maneuver was done within the opposing esophageal wall, with magnet placement in the opposing subadventitial space.

RESULTS

Submucosal tunnels and subadventitial tunnels were successful without perforation ex vivo in all attempts and in 9 of 10 cases, respectively. Magnets were deployed in the subadventitial space in 7 cases. Magnets connected and separated with atraumatic endoscope passage into the stomach and reconnected when the endoscope was withdrawn under fluoroscopy in 5 of 7 cases (71.4%). In vivo submucosal tunnels and subadventitial tunnels were successful in all 5 cases, and magnet augmentation was functionally active in 4 cases (80%).

CONCLUSION

Subadventitial tunnels were feasible and could represent a new working space for endoscopic treatment. Endoscopic placement of magnets within the subadventitial space may be an attractive alternative endolumenal therapy for GERD.

Laparoscopic magnetic sphincter augmentation versus double-dose proton pump inhibitors for management of moderate-to-severe regurgitation in GERD: a randomized controlled trial

BACKGROUND AND AIMS

GERD patients frequently complain of regurgitation of gastric contents. Medical therapy with proton-pump inhibitors (PPIs) is frequently ineffective in alleviating regurgitation symptoms, because PPIs do nothing to restore a weak lower esophageal sphincter. Our aim was to compare effectiveness of increased PPI dosing with laparoscopic magnetic sphincter augmentation (MSA) in patients with moderate-to-severe regurgitation despite once-daily PPI therapy.

METHODS

One hundred fifty-two patients with GERD, aged ≥21 years with moderate-to-severe regurgitation despite 8 weeks of once-daily PPI therapy, were prospectively enrolled at 21 U.S. sites. Participants were randomized 2:1 to treatment with twice-daily (BID) PPIs (N = 102) or to laparoscopic MSA (N = 50). Standardized foregut symptom questionnaires and ambulatory esophageal reflux monitoring were performed at baseline and at 6 months. Relief of regurgitation, improvement in foregut questionnaire scores, decrease in esophageal acid exposure and reflux events, discontinuation of PPIs, and adverse events were the measures of efficacy.

RESULTS

Per protocol, 89% (42/47) of treated patients with MSA reported relief of regurgitation compared with 10% (10/101) of the BID PPI group (P < .001) at the 6-month primary endpoint. By intention-to-treat analysis, 84% (42/50) of patients in the MSA group and 10% (10/102) in the BID PPI group met this primary endpoint (P < .001). Eighty-one percent (38/47) of patients with MSA versus 8% (7/87) of patients with BID PPI had ≥50% improvement in GERD-health-related quality of life scores (P < .001), and 91% (43/47) remained off of PPI therapy. A normal number of reflux episodes and acid exposures was observed in 91% (40/44) and 89% (39/44) of MSA patients, respectively, compared with 58% (46/79) (P < .001) and 75% (59/79) (P = .065) of BID PPI patients at 6 months. No significant safety issues were observed. In MSA patients, 28% reported transient dysphagia; 4% reported ongoing dysphagia.

CONCLUSION

Patients with GERD with moderate-to-severe regurgitation, especially despite once-daily PPI treatment, should be considered for minimally invasive treatment with MSA rather than increased PPI therapy. (Clinical trial registration number: NCT02505945.).

Reflux and Belching after Laparoscopic 270 degree Posterior Versus 180 degree Anterior Partial Fundoplication

BACKGROUND

Laparoscopic 270 degree posterior, or Toupet (LTF), and 180 degree anterior partial fundoplication (LAF) ensure equal reflux control and reduce the risk of gas-related symptoms compared to 360 degree (Nissen) fundoplication. It is unclear which type of partial fundoplication is superior in preventing gas-related side-effects. The aim of this study was to determine differences in effect of LTF and LAF on reflux characteristics and belching patterns.

METHODS

Upper gastrointestinal endoscopy, esophageal manometry, and 24-h combined pH-impedance monitoring were performed before and 6 months after fundoplication (n = 10, LTF vs. n = 10, LAF). Observed changes after surgery (∆) were compared between the two procedures.

RESULTS

Symptomatic reflux control as well as the reduction in the mean number of acid (∆ - 58.5 vs. - 66.5; P = 0.912), liquid (∆ - 17.0 vs. - 43.5; P = 0.247), and mixed liquid gas reflux episodes (∆ - 38.0 vs. - 40.0; P = 0.579) were comparable following LTF and LAF. There were no differences in the mean number of weakly acidic reflux episodes after LTF and LAF (1.0 (0.8-4) vs. 1.0 (0-3), P = 0.436). The reduction in proximal (P = 1.000), mid-esophageal (P = 0.063), and distal reflux episodes (P = 0.315) was comparable. Both procedures equally reduced the number of gastric belches (P = 0.278) and supragastric belches (P = 0.123), with no significant reduction in the number of air swallows after either procedure (P = 0.278).

CONCLUSION

LTF and LAF provide similar reflux control, with a comparable effect on acidic, liquid, and gas reflux. Both procedures equally reduced the number of belches and supragastric belches. This study provides the physiological evidence for the published randomized trials reporting similar symptomatic outcome after both types of partial fundoplication.

Complications of Antireflux Surgery

Antireflux surgery anatomically restores the antireflux barrier and is a therapeutic option for proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease or PPI intolerance. Laparoscopic fundoplication is the standard antireflux surgery, though its popularity has declined due to concerns regarding wrap durability and adverse events. As the esophagogastric junction is an anatomically complex and dynamic area subject to mechanical stress, wraps are susceptible to disruption, herniation or slippage. Additionally, recreating an antireflux barrier to balance bidirectional bolus flow is challenging, and wraps may be too tight or too loose. Given these complexities it is not surprising that post-fundoplication symptoms and complications are common. Perioperative mortality rates range from 0.1 to 0.2% and prolonged structural complications occur in up to 30% of cases. Upper gastrointestinal endoscopy with a comprehensive retroflexed examination of the fundoplication and barium esophagram are the primary tests to assess for structural complications. Management hinges on differentiating complications that can be managed with medical and lifestyle optimization versus those that require surgical revision. Reoperation is best reserved for severe structural abnormalities and troublesome symptoms despite medical and endoscopic therapy given its increased morbidity and mortality. Though further data are needed, magnetic sphincter augmentation may be a safer alternative to fundoplication.

Outcome for Patients With Pathological Esophageal Acid Exposure After Laparoscopic Fundoplication

OBJECTIVE

The aim of the current study was to assess symptomatic outcome and need for surgical reintervention for patients identified with pathological esophageal acid exposure by routine postoperative 24-hour pH-monitoring.

BACKGROUND

Although laparoscopic fundoplication is associated with excellent short- and midterm results, recurrent symptoms pose an important challenge. Postoperative pH-monitoring is considered the "gold standard" for diagnosing recurrent GERD and frequently used for routine postoperative follow up.

METHODS

Analysis of prospectively collected data from patients who underwent laparoscopic fundoplication between April 1994 and June 2015 and underwent routine postoperative 24-hour pH-monitoring was performed. Symptomatic outcome and need for surgical reintervention up to 5 years was compared between patients with pathological and physiological postoperative esophageal acid exposure. Primary endpoints were heartburn score and need for surgical reintervention for recurrent reflux.

RESULTS

A total of 309 patients in whom routine postoperative 24-hour pH-monitoring was performed were included. Pathological acid exposure was present in 33 patients (11%) compared with 276 patients (89%) with physiological acid exposure. During 5-year follow up, there were no differences in heartburn, dysphagia, or satisfaction scores. Eighteen percent of all patients with abnormal postoperative pH-studies underwent redo fundoplication during 5-year follow up.

CONCLUSIONS

Pathological acid exposure demonstrated by routine postoperative pH-monitoring was not associated with worse symptomatic outcome in terms of reflux control and satisfaction. A possible explanation for this finding is that laparoscopic fundoplication reduces the patients' ability to perceive reflux. This underlines the importance of assessing the association between symptomatic outcome and esophageal function tests in determining outcome of antireflux surgery.

A modified Nissen fundoplication: subjective and objective midterm results

PURPOSE

The failure rate of laparoscopic anti-reflux surgery is approximately 10-20%. The aim of our prospective study was to investigate whether a modified Nissen fundoplication (MNF) can improve reflux symptoms and prevent surgical treatment failure in the midterm.

METHODS

The MNF consisted of (1) suturing the esophagus to the diaphragmatic crura on each side using four non-absorbable stitches, (2) reinforcing clearly weak crura with a tailored Ultrapro mesh, and (3) fixing the upper stitch of the valve to the diaphragm. Forty-eight consecutive patients experiencing typical gastroesophageal reflux disease (GERD) symptoms at least three times per week for 6 months or longer were assessed before and after surgery using validated symptom and quality of life (GERD-HRQL) questionnaires, high-resolution manometry, 24-h impedance-pH monitoring, endoscopy, and barium swallow.

RESULTS

Mortality and perioperative complications were nil. At median follow-up of 46.7 months, the patients experienced significant improvements in symptom and GERD-HRQL scores. One patient presented with severe dyspepsia and another complained of dysphagia requiring a repeat surgery 12 months after the first operation. Esophageal acid exposure (8.8 vs 0.1; p < 0.0001), reflux number (62 vs 8.5; p < 0.0001), and symptom-reflux association (19 vs 0; p < 0.0001) significantly decreased postoperatively. The median esophagogastric junction contractile integral (EGJ-CI) from 31 cases (8.2 vs 21.2 mmHg cm; p = 0.0003) and the abdominal length of the lower esophageal sphincter (LES) (0 vs 16 mm; p = 0.01) increased postoperatively.

CONCLUSIONS

Our data demonstrate that the MNF is a safe and effective procedure both in the short term and midterm.

Post-fundoplication symptoms and complications: Diagnostic approach and treatment

Laparoscopic Nissen fundoplication is currently considered the surgical treatment of choice for gastroesophageal reflux disease (GERD) and its long-term effectiveness is above 90%. Adequate patient selection and the experience of the surgeon are among the predictive factors of good clinical response. However, there can be new, persistent, and recurrent symptoms after the antireflux procedure in up to 30% of the cases. There are numerous causes, but in general, they are due to one or more anatomic abnormalities and esophageal and gastric function alterations. When there are persistent symptoms after the surgical procedure, the surgery should be described as "failed". In the case of a patient that initially manifests symptom control, but the symptoms then reappear, the term "dysfunction" could be used. When symptoms worsen, or when symptoms or clinical situations appear that did not exist before the surgery, this should be considered a "complication". Postoperative dysphagia and dyspeptic symptoms are very frequent and require an integrated approach to determine the best possible treatment. This review details the pathophysiologic aspects, diagnostic approach, and treatment of the symptoms and complications after fundoplication for the management of GERD.

Esophageal Penetration of the Magnetic Sphincter Augmentation Device: History Repeats Itself

BACKGROUND

An alternative approach to the treatment of gastroesophageal reflux disease (GERD) has recently been introduced in clinical practice, involving the implantation of a magnetic sphincter augmentation device (MSAD). This "magnetic ring" is implanted laparoscopically around the lower esophageal sphincter to improve its barrier function. The literature is still limited on the midterm results achieved in controlling reflux because the MSAD is a very new procedure. So far, only a few cases of the MSAD causing erosion of the esophagus have been reported.

METHODS

We report on two cases of progressive and severe dysphagia after the implantation of an MSAD elsewhere. In both cases, the symptoms were caused by the migration of the device into the esophagus.

RESULTS

The devices were removed endoscopically in a single step in both cases, using the Olympus cutter. After 3 months, the first patient had a laparoscopic Nissen fundoplication without any complications and with a good final reflux control. The second only underwent removal of the device, using the same endoscopic approach and again without any complications.

CONCLUSIONS

Judging from the literature, MSAD implantation may be an effective way to control GERD, but the method can carry major complications, such as migration of the device into the esophagus (as in the two cases reported here). Endoscopic removal of a device possibly penetrating inside the esophagus is feasible and safe, and may later be followed up with a laparoscopic antireflux procedure without any particular difficulty.

A modification of Nissen fundoplication improves patients' outcome and may reduce procedure-related failure rate

BACKGROUND

Laparoscopic anti-reflux surgery has a failure rate of 10-20%. We aimed to investigate whether a modification of Nissen fundoplication (MNF) may improve patients' outcome and reduce failure rate.

MATERIALS & METHODS

We prospectively compared 40 consecutive patients with gastroesophageal reflux disease who underwent anti-reflux surgery: 20 Nissen fundoplication (NF) and 20 the MNF approach. Eight cases in the MNF group needed redo surgery. The MNF consisted in suturing the esophagus to the diaphragmatic crura on each side by means of 4 non-absorbable stitches and in fixing the upper stitch of the valve to diaphragm. In case of clearly weak crura, a reinforcement with Ultrapro mesh was used. All patients were assessed before and after surgery using validated symptoms and quality of life (GERD-HRQL) questionnaires, manometry and 24-h impedance-pH monitoring, endoscopy and barium-swallow.

RESULTS

Mortality and postoperative complications were nil. At a median follow-up of 36 months, no significant differences emerged between the MNF and NF group in terms of symptoms, GERD-HRQL scores, manometric findings, and impedance-pH features. Dysphagia was not reported by the MNF group, while it was quite common (20% vs.0%, p = ns) in the NF group. Anti-reflux surgery was successful in all patients in the MNF group, whereas two patients in the NF group presented a slipped wrap and one recurrent reflux; two of these cases required redo-surgery (10% vs. 0%, p = ns).

CONCLUSIONS

Our preliminary data demonstrated that the MNF is a safe and effective procedure. Further, it seems to reduce the failure rate associated to the surgical procedure.

Fundoplication for Gastroesophageal Reflux Disease: Tips for Success

Gastroesophageal reflux disease affects almost 20% of the population in the United States. Today, proton pump inhibitors are the most frequently prescribed drugs, with an estimated cost of 10 billion dollars per year. Although these medications control heartburn in the majority of patients, other symptoms such as regurgitation and respiratory symptoms often are not controlled, particularly in patients with large hiatal hernias. In these patients a properly performed laparoscopic fundoplication controls esophageal and extraesophageal symptoms and avoids life-long medical therapy. Key elements for the success of a fundoplication are careful patient selection, a complete preoperative evaluation, and a properly executed operation.

Laparoscopic antireflux surgery increases health-related quality of life in children with GERD

INTRODUCTION

Improving health-related quality of life (HRQoL) is increasingly recognized as an essential part of patient care outcome. Little is known about the effect of laparoscopic antireflux surgery (LARS) on the HRQoL in the pediatric patients. The aims of this study were to evaluate the effect of LARS on HRQoL in children with gastroesophageal reflux disease (GERD) and to identify predictors that influence HRQoL outcome after LARS.

METHODS

Between 2011 and 2013, 25 patients with therapy-resistant GERD [median age 6 (2-18) years] were included prospectively. Caregivers and children with normal neurodevelopment (>4 years) were asked to fill out the validated PedsQL 4.0 Generic Core Scales before and 3-4 months after LARS.

RESULTS

The PedsQL was completed by all caregivers (n = 25) and 12 children. HRQoL total score improved significantly after LARS, both from a parental (p = 0.009) and child's perspective (p = 0.018). The psychosocial health summary and physical health summary scores also improved significantly after LARS. HRQoL before and after LARS was significantly lower in children with impaired neurodevelopment (p < 0.001). However, neurodevelopment did not influence the effect of LARS on HRQoL. The only significant predictor for improvement in HRQoL after LARS was age at the time of operation (p = 0.001).

CONCLUSIONS

HRQoL significantly improves after LARS. Although children with impaired neurodevelopment had lower overall HRQoL, neurodevelopment by itself does not predict inferior improvement in HRQoL after LARS. Older children have a more favorable HRQoL outcome after LARS compared to younger children. This may suggest caution when considering LARS in younger GERD patients.

Effects and efficacy of laparoscopic fundoplication in children with GERD: a prospective, multicenter study

INTRODUCTION

Laparoscopic antireflux surgery (LARS) in children primarily aims to decrease reflux events and reduce reflux symptoms in children with therapy-resistant gastroesophageal reflux disease (GERD). The aim was to objectively assess the effect and efficacy of LARS in pediatric GERD patients and to identify parameters associated with failure of LARS.

METHODS

Twenty-five children with GERD [12 males, median age 6 (2-18) years] were included prospectively. Reflux-specific questionnaires, stationary manometry, 24-h multichannel intraluminal impedance pH monitoring (MII-pH monitoring) and a ¹³C-labeled Na-octanoate breath test were used for clinical assessment before and 3 months after LARS.

RESULTS

After LARS, three of 25 patients had persisting/recurrent reflux symptoms (one also had persistent pathological acid exposure on MII-pH monitoring). New-onset dysphagia was present in three patients after LARS. Total acid exposure time (AET) (8.5-0.8 %; p < 0.0001) and total number of reflux episodes (p < 0.001) significantly decreased and lower esophageal sphincter (LES) resting pressure significantly increased (10-24 mmHg, p < 0.0001) after LARS. LES relaxation, peristaltic contractions and gastric emptying time did not change. The total number of reflux episodes on MII-pH monitoring before LARS was a significant predictor for the effect of the procedure on reflux reduction (p < 0.0001).

CONCLUSIONS

In children with therapy-resistant GERD, LARS significantly reduces reflux symptoms, total acid exposure time (AET) and number of acidic as well as weakly acidic reflux episodes. LES resting pressure increases after LARS, but esophageal function and gastric emptying are not affected. LARS showed better reflux reduction in children with a higher number of reflux episodes on preoperative MII-pH monitoring.

Long-term Outcomes of Patients Receiving a Magnetic Sphincter Augmentation Device for Gastroesophageal Reflux

BACKGROUND & AIMS

Based on results from year 2 of a 5-year trial, in 2012 the US Food and Drug Administration approved the use of a magnetic device to augment lower esophageal sphincter function in patients with gastroesophageal reflux disease (GERD). We report the final results of 5 years of follow-up evaluation of patients who received this device.

METHODS

We performed a prospective study of the safety and efficacy of a magnetic device in 100 adults with GERD for 6 months or more, who were partially responsive to daily proton pump inhibitors (PPIs) and had evidence of pathologic esophageal acid exposure, at 14 centers in the United States and The Netherlands. The magnetic device was placed using standard laparoscopic tools and techniques. Eighty-five subjects were followed up for 5 years to evaluate quality of life, reflux control, use of PPIs, and side effects. The GERD-health-related quality of life (GERD-HRQL) questionnaire was administered at baseline to patients on and off PPIs, and after placement of the device; patients served as their own controls. A partial response to PPIs was defined as a GERD-HRQL score of 10 or less on PPIs and a score of 15 or higher off PPIs, or a 6-point or more improvement when scores on vs off PPI were compared.

RESULTS

Over the follow-up period, no device erosions, migrations, or malfunctions occurred. At baseline, the median GERD-HRQL scores were 27 in patients not taking PPIs and 11 in patients on PPIs; 5 years after device placement this score decreased to 4. All patients used PPIs at baseline; this value decreased to 15.3% at 5 years. Moderate or severe regurgitation occurred in 57% of subjects at baseline, but only 1.2% at 5 years. All patients reported the ability to belch and vomit if needed. Bothersome dysphagia was present in 5% at baseline and in 6% at 5 years. Bothersome gas-bloat was present in 52% at baseline and decreased to 8.3% at 5 years.

CONCLUSIONS

Augmentation of the lower esophageal sphincter with a magnetic device provides significant and sustained control of reflux, with minimal side effects or complications. No new safety risks emerged over a 5-year follow-up period. These findings validate the long-term safety and efficacy of the magnetic sphincter augmentation device for patients with GERD.

A Novel Sleep Positioning Device Reduces Gastroesophageal Reflux: A Randomized Controlled Trial

GOAL

We hypothesized that sleeping left-side down with the head/torso elevated reduces recumbent gastroesophageal reflux (GER).

BACKGROUND

Previous studies show that sleeping with head of bed elevated or on wedge reduces GER and lying left-side down reduces GER versus right-side down and supine. No prior studies have evaluated the potential compounding effects of lying in an inclined position combined with lateral positioning on GER.

STUDY

We evaluated a sleep-positioning device (SPD) consisting of an inclined base and body pillow that maintains lateral position while elevating the head/torso. This was a single institution, randomized controlled trial involving 20 healthy volunteers receiving 4 six-hour impedance-pH tests. After placement of reflux probe, subjects returned home, ate standardized meal, and lay down in randomly assigned positions: SPD right-side down (SPD-R), SPD left-side down (SPD-L), standard wedge any position (W), or flat any position (F). A wireless accelerometer documented position during each study. Number of reflux episodes (RE) and esophageal acid exposure (EAE) were calculated over 6 hours.

RESULTS

Significantly less EAE occurred during sleeping SPD-L versus sleeping W, SPD-R, and F. The most EAE occurred during sleeping SPD-R despite use of the positioning device. RE were significantly less SPD-L than SPD-R. Patients sleeping SPD-L and SPD-R spent the majority of first 2 hours and greater than half of 6 hours in assigned position. Patients sleeping W and F averaged more time supine than right or left.

CONCLUSIONS

The sleep positioning device maintains recumbent position effectively. Lying left-side down, it reduces recumbent esophageal acid exposure.

Laparoscopic fundoplication for gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is a condition that develops when the reflux of gastric contents into the esophagus leads to troublesome symptoms and/or complications. Heartburn is the cardinal symptom, often associated with regurgitation. In patients with endoscopy-negative heartburn refractory to proton pump inhibitor (PPI) therapy and when the diagnosis of GERD is in question, direct reflux testing by impedance-pH monitoring is warranted. Laparoscopic fundoplication is the standard surgical treatment for GERD. It is highly effective in curing GERD with a 80% success rate at 20-year follow-up. The Nissen fundoplication, consisting of a total (360°) wrap, is the most commonly performed antireflux operation. To reduce postoperative dysphagia and gas bloating, partial fundoplications are also used, including the posterior (Toupet) fundoplication, and the anterior (Dor) fundoplication. Currently, there is consensus to advise laparoscopic fundoplication in PPI-responsive GERD only for those patients who develop untoward side-effects or complications from PPI therapy. PPI resistance is the real challenge in GERD. There is consensus that carefully selected GERD patients refractory to PPI therapy are eligible for laparoscopic fundoplication, provided that objective evidence of reflux as the cause of ongoing symptoms has been obtained. For this purpose, impedance-pH monitoring is regarded as the diagnostic gold standard.

Would you have laparoscopic Nissen fundoplication again? A patient satisfaction survey in a UK population

OBJECTIVE

Laparoscopic Nissen fundoplication (LNF) effectively reduces objective gastro-oesophageal reflux. It can however cause side effects which affect quality of life or fail to improve subjective reflux symptoms. This study aims to assess patient satisfaction following LNF by assessing whether patients would have the procedure again.

DESIGN

Telephone survey using a structured questionnaire. Participation was voluntary.

SETTING

UK Foundation Trust (two university hospitals).

PATIENTS

All patients who had LNF performed by a single surgeon between November 2008 and June 2012.

MAIN OUTCOME MEASURES

Primarily, current reflux symptoms, antiacid medication requirement and whether participants would choose to have the procedure again (should they still have their initial symptoms). Further measures were conversion to open procedure, need for redo or reversal, and mortality.

RESULTS

99 patients underwent LNF in the quoted period; 71 were contactable and willing to participate. Of the 99, two required redo operations (neither of whom was contactable), and one had a reversal (primary operation included). Median time since the operation was 33 months (range 5-48 months). Compared with preoperatively, 72% rated their current reflux-symptom severity as ≤2/10, 23% as 3-6/10 and 4% as 7-10/10. 75% were not taking any antiacid medication. 89% of patients said that they would have the procedure again.

CONCLUSIONS

This study provides supporting evidence that LNF improves reflux symptoms and decreases medication use at intermediate-term follow-up. These results will aid counselling and reassurance of patients regarding the risks and benefits of LNF as the majority of postoperative patients were sufficiently satisfied to choose the operation again.

Identification of preoperative risk factors for persistent postoperative dysphagia after laparoscopic antireflux surgery

BACKGROUND

Postoperative dysphagia is common after antireflux surgery and generally runs a self-limiting course. Nevertheless, part of these patients report long-term dysphagia. Inadequate surgical technique is a well documented cause of this result.

AIM

This retrospective study evaluated the preoperative risk factors not surgery-related for persistent dysphagia after primary laparoscopic antireflux surgery.

METHODS

Patients who underwent laparoscopic antireflux surgery by the modified technique of Nissen were evaluated in the preoperative period retrospectively. Postoperative severity of dysphagia was evaluated prospectively using a stantardized scale. Dysphagia after six weeks were defined as persistent. Statistical tests of association and logistic regression were used to identify risk factors associated with persistent dysphagia.

RESULTS

A total of 55 patients underwent primary antireflux surgery by a single surgeon team. Of these, 25 patients had preoperative dysphagia (45,45%). Persistent postoperaive dysphagia was reported by 20 (36,36%). Ten patients (18,18%) required postoperative endoscopic dilatation for dysphagia. There was statistical association between satisfaction with surgery and postoperative dysphagia and requiring the use of antireflux medication after the procedure; and between preoperative dysphagia and postoperative dysphagia. Logistic regression identified significant preopertive dysphagia as risk factor for persistent postoperative dysphagia. No correlations were found with preoperative manometry.

CONCLUSIONS

Patients with significant preoperative dysphagia were more likely to report persistent postoperative dysphagia. This study confirms that the current manometric criteria used to define esophageal dysmotility are not reliable to identify patients at risk for post-fundoplication dysphagia. Minucious review of the clinical history about the presence and intensity of preoperative dysphagia is important in the selection of candidates for antireflux surgery.

A comparative trial of laparoscopic magnetic sphincter augmentation and Nissen fundoplication

BACKGROUND

Laparoscopic magnetic sphincter augmentation (MSA) with the LINX device is a promising new therapy for the treatment of gastroesophageal reflux disease (GERD). Initial studies have demonstrated MSA to be safe and effective. However, no direct comparison between MSA and laparoscopic Nissen fundoplication (LNF), the gold standard surgical therapy for GERD, has been performed.

METHODS

A single institution, case-control study was conducted of MSA performed from 2012 to 2013 and a cohort of LNF matched for age, gender, and hiatal hernia size.

RESULTS

MSA and LNF were both effective treatments for reflux with 75 and 83 % of patients, respectively, reporting resolution of GERD at short-term follow-up. Dysphagia was common following both MSA and LNF, but severe dysphagia requiring endoscopic dilation was more frequent after MSA (50 vs. 0 %, p = 0.01). Need for dilation did not correlate with size of the LINX device or any other examined patient factors. A trend toward decreased adverse GI symptoms of bloating, flatulence, and diarrhea was seen after MSA compared to LNF (0 vs. 33 %). MSA had a shorter operative time (64 vs. 90 min, p < 0.01) but other peri-operative outcomes, including pain, morbidity, and re-admissions were equivalent to LNF. MSA patients were more likely to be self-referred (58 vs. 0 %, p < 0.001).

CONCLUSIONS

MSA and LNF are both effective and safe treatments for GERD; however, severe dysphagia requiring endoscopic intervention is more common with MSA. Other adverse GI side effects may be less frequent after MSA. Consideration should be paid to these distinct post-operative symptom profiles when selecting a surgical therapy for reflux disease.

Short-term outcomes using magnetic sphincter augmentation versus Nissen fundoplication for medically resistant gastroesophageal reflux disease

BACKGROUND

In 2012 the United States Food and Drug Administration approved implantation of a magnetic sphincter to augment the native reflux barrier based on single-series data. We sought to compare our initial experience with magnetic sphincter augmentation (MSA) with laparoscopic Nissen fundoplication (LNF).

METHODS

A retrospective case-control study was performed of consecutive patients undergoing either procedure who had chronic gastrointestinal esophageal disease (GERD) and a hiatal hernia of less than 3 cm.

RESULTS

Sixty-six patients underwent operations (34 MSA and 32 LNF). The groups were similar in reflux characteristics and hernia size. Operative time was longer for LNF (118 vs 73 min) and resulted in 1 return to the operating room and 1 readmission. Preoperative symptoms were abolished in both groups. At 6 months or longer postoperatively, scores on the Gastroesophageal Reflux Disease Health Related Quality of Life scale improved from 20.6 to 5.0 for MSA vs 22.8 to 5.1 for LNF. Postoperative DeMeester scores (14.2 vs 5.1, p=0.0001) and the percentage of time pH was less than 4 (4.6 vs 1.1; p=0.0001) were normalized in both groups but statistically different. MSA resulted in improved gassy and bloated feelings (1.32 vs 2.36; p=0.59) and enabled belching in 67% compared with none of the LNFs.

CONCLUSIONS

MSA results in similar objective control of GERD, symptom resolution, and improved quality of life compared with LNF. MSA seems to restore a more physiologic sphincter that allows physiologic reflux, facilitates belching, and creates less bloating and flatulence. This device has the potential to allow individualized treatment of patients with GERD and increase the surgical treatment of GERD.

DYSPHAGIA AFTER LAPAROSCOPIC TOTAL FUNDOPLICATION: anterior or posterior gastric wall fundoplication?

ContextThe occurrence of severe dysphagia after laparoscopic total fundoplication is currently an important factor associated with loss of quality of life in patients undergoing this modality of treatment for gastroesophageal reflux disease.ObjectivesCompare the incidence and evaluate the causes of severe postoperative dysphagia in patients undergoing laparoscopic total fundoplication (LTF) without short gastric vessels division, using the anterior gastric wall (Rossetti LTF) or anterior and posterior gastric walls (Nissen LTF).MethodsAnalysis of the data of 289 patients submitted to LTF without short gastric vessels division from January 2004 to January 2012, with a minimum follow-up of 6 months. Patients were divided in Group 1 (Rossetti LTF – n = 160) and Group 2 (Nissen LTF – n = 129).ResultsThe overall incidence of severe postoperative dysphagia was 3.11% (4.37% in group 1 and 1.55% in group 2; P = 0.169). The need for surgical treatment of dysphagia was 2.5% in group 1 and 0.78% in group 2 (= 0.264). Distortions of the fundoplication were identified as possible causes of the dysphagia in all patients taken to redo fundoplication after Rossetti LTF. No wrap distortion was seen in redo fundoplication after Nissen LTF.ConclusionsThe overall incidence of severe postoperative dysphagia did not differ on the reported techniques. Only Rossetti LTF was associated with structural distortion of the fundoplication that could justify the dysphagia.

One hundred consecutive patients treated with magnetic sphincter augmentation for gastroesophageal reflux disease: 6 years of clinical experience from a single center

BACKGROUND

This study was undertaken to evaluate our clinical experience during a 6-year period with an implantable device that augments the lower esophageal sphincter for gastroesophageal reflux disease (GERD). The device uses magnetic sphincter augmentation (MSA) to strengthen the antireflux barrier.

STUDY DESIGN

In a single-center, prospective case series, 100 consecutive patients underwent laparoscopic MSA for GERD between March 2007 and February 2012. Clinical outcomes for each patient were tracked post implantation and compared with presurgical data for esophageal pH measurements, symptom scores, and proton pump inhibitor (PPI) use.

RESULTS

Median implant duration was 3 years (range 378 days to 6 years). Median total acid exposure time was reduced from 8.0% before implant to 3.2% post implant (p < 0.001). The median GERD Health Related Quality of Life score at baseline was 16 on PPIs and 24 off PPIs and improved to a score of 2 (p < 0.001). Freedom from daily dependence on PPIs was achieved in 85% of patients. There have been no long-term complications, such as device migrations or erosions. Three patients had the device laparoscopically removed for persistent GERD, odynophagia, or dysphagia, with subsequent resolution of symptoms.

CONCLUSIONS

Magnetic sphincter augmentation for GERD in clinical practice provides safe and long-term reduction of esophageal acid exposure, substantial symptom improvement, and elimination of daily PPI use. For candidates of antireflux surgery who have been carefully evaluated before surgery to confirm indication for MSA, MSA has become a standard treatment at our institution because control of reflux symptoms and pH normalization can be achieved with minimal side effects and preservation of gastric anatomy.
