[PMID: 38722379 PMCID: PMC11133156 DOI: 10.1007/s00464-024-10851-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Accepted: 04/10/2024] [Indexed: 05/30/2024]
Abstract
INTRODUCTION The introduction of the functional lumen imaging probe (FLIP) has provided objective, real-time feedback on the geometric variations with each component of a hiatal hernia repair (HHR). The utility of this technology in altering intraoperative decision-making has been scarcely reported. Herein, we report a single-center series of intraoperative FLIP during HHR. METHODS A retrospective review of electronic medical records between 2020 and 2022 was conducted and all patients undergoing non-recurrent HHR with FLIP were queried. Patient and hernia characteristics, intraoperative FLIP values and changes in decision-making, as well as early post-operative outcomes were reported. Both diameter and distensibility index (DI) were measured at 40 ml and 50 ml balloon inflation after hiatal dissection, after hiatal closure, and after fundoplication when indicated. RESULTS Thirty-three patients met inclusion criteria. Mean age was 62 ± 14 years and mean BMI was 28 ± 6 kg/m2. The majority (53%) were type I hiatal hernias. The largest drop in DI occurred after hiatal closure, with minimal change seen after fundoplication (mean DI of 4.3 ± 2. after completion of HH dissection, vs 2.7 ± 1.2 after hiatal closure and 2.3 ± 1 after fundoplication when performed). In 13 (39%) of cases, FLIP values directly impacted intraoperative decision-making. Fundoplication was deferred in 4/13 (31%) patients, the wrap was loosened in 2/13 (15%); the type of fundoplication was altered to achieve adequate anti-reflux values in 2/13 (15%) patients, and in 1/13 (3%) the wrap was tightened. CONCLUSION FLIP measurements can be used intraoperatively to guide decision-making and alter management plan based on objective values. Long-term outcomes and further prospective studies are required to better delineate the value of this technology.

Abstract
Gastroesophageal reflux disease (GERD), a prevalent condition with multifactorial pathogenesis, involves esophageal motor dysmotility as a key contributing factor to its development. When suspected GERD patients have an inadequate response to proton-pump inhibitor (PPI) therapy and normal upper endoscopy results, high-resolution manometry (HRM) is utilized to rule out alternative diagnosis such as achalasia spectrum disorders, rumination, or supragastric belching. At present, HRM continues to provide supportive evidence for diagnosing GERD and determining the appropriate treatment. This review focuses on the existing understanding of the connection between esophageal motor findings and the pathogenesis of GERD, along with the significance of esophageal HRM in managing GERD patients. The International GERD Consensus Working Group introduced a three-step method, assessing the esophagogastric junction (EGJ), esophageal body motility, and contraction reserve with multiple rapid swallow (MRS) maneuvers. Crucial HRM abnormalities in GERD include frequent transient lower esophageal sphincter relaxations, disrupted EGJ, and esophageal body hypomotility. Emerging HRM metrics like EGJ-contractile integral and innovative provocative maneuver like straight leg raise have the potential to enhance our understanding of factors contributing to GERD, thereby increasing the value of HRM performed in patients who experience symptoms suspected of GERD.

Abstract
Background and Aim Previous studies on age differences in proton pump inhibitor (PPI)-resistant reflux esophagitis (RE) have found that stenosis and bleeding complications were significantly more common in the elderly than in the non-elderly. We sought to examine differences between two groups of elderly (75 years or older) and non-elderly (<75 years) patients with (PPI)-resistant severe RE and also the efficacy of vonoprazan (VPZ) in these patients. Methods There were 14 patients in the elderly group and 15 in the non-elderly group. Information was obtained on patient background (sex, body mass index [BMI], gastric mucosal atrophy, and the presence of hernia and collagen disease), and all patients underwent the saliva secretion test and esophagogastroduodenoscopy (EGD). The saliva secretion test (amount of saliva secreted, salivary pH, and the acid-buffering capacity) was performed by chewing sugar-free gum for 3 min before EGD. The efficacy of VPZ in both groups was also assessed. Results Saliva secretion, sex, BMI, and the presence of gastric mucosal atrophy did not significantly differ between the two groups. The number of hernias larger than 4 cm was significantly higher in the elderly PPI-resistant group, and significantly more patients had collagen disease in the non-elderly group. The efficacy of VPZ was not significantly different between the two groups; however, 10 patients in the non-elderly group had collagen disease, and 4 did not achieve esophageal mucosal healing even with VPZ 20 mg. Conclusion The number of large hernias (>4 cm) was significantly higher in the elderly group, while significantly more non-elderly patients had collagen disease. In the non-elderly group with scleroderma, the efficacy of VPZ 20 mg may not be sufficient.

Abstract
INTRODUCTION The Valsalva maneuver and its modifications have been utilized across several conditions in medicine; however, there have been difficulties in its application. Thus, at the University of Texas Health Science Center in San Antonio, we designed and patented an affordable and accessible device that mimics Valsalva called "Forced Inspiratory Suction and Swallow Tool (FISST). AREAS COVERED In this review, we discuss the premise for the design of FISST, based on applications of the law of conservation energy, the continuity equation, and Bernoulli's principle. We then detail the mechanism by which FISST stimulates hiccup cessation by increasing negative inspiratory pressure when drinking through the apparatus, causing diaphragmatic contraction and disruption of the hiccup reflex. We then detail the efficacy and future applications of FISST in addressing other pathologies. EXPERT OPINION FISST has been used to address hiccups by utilizing its reverse-Valsalva effect to increase parasympathetic stimulation by increasing vagal tone. In a prospective study that we conducted on a cohort of 249 hiccup subjects worldwide, this tool achieved 92% effectiveness. Additionally, several cases, including a published case report, have found FISST successful in terminating supraventricular tachycardias (SVT). FISST may be further utilized in diagnosing or addressing various upper airway pathologies and should be explored further.

Abstract
Laparoscopic placement of the LINX Magnetic Sphincter Augmentation (MSA) device has become an accepted alternative to fundoplication in appropriate patients. Initial studies of MSA targeted to patients with 'early' disease allowed for the most minimal dissection of the esophagus to place the device, without hiatal dissection or repair (NoHHR), in patients with no or minimal hernia findings at surgery. Subsequent studies have compared systematic formal hiatal dissection and repair (Formal HHR) with the original minimal dissection technique. Review of published literature on MSA includes discussion on treatment of hiatal hernia at the time of implantation, accompanying the review of the physiology of the crural diaphragm. Formal hiatal hernia repair at the time of MSA implantation results in better control of reflux with less dysphagia and risk of postoperative hernia than NoHHR, regardless of the presence or size of hiatal hernia. Systematic crural repair should accompany any MSA implantation regardless of the presence or size of hiatal hernia.

Abstract
The diagnosis of hiatal hernia (HH), causing severe gastroesophageal reflux disease and complications in children with cerebral palsy (CP) is cumbersome because invasive investigations are required for diagnosis. Hip displacement, one of the most common complications in children with CP, can be diagnosed with a simple pelvic radiograph. This study aimed to evaluate the association between the severity of hip displacement and HH and the diagnostic accuracy of Reimers' hip migration percentage (MP) on pelvic radiography in assessing the presence of HH. A total of 52 children with CP (27 boys, 25 girls; mean age, 6.3 years; range, 0.6-17.4 years) who underwent esophagogastroduodenoscopy, upper gastrointestinal series and pelvic radiography between March 2013 and February 2020 were recruited. Demographic and clinical characteristics, as well as endoscopic and radiological findings, were evaluated and statistically analyzed. HH was defined as ≥ 2 cm proximal displacement of the gastroesophageal junction identified in esophagogastroduodenoscopy or upper gastrointestinal series, and MP was calculated by evaluating the pelvic radiograph. Of the 52 children enrolled in this study, HH was diagnosed in 18 children (34.6%). When the patients were classified and analyzed according to the MP result, HH was observed in 10%, 26.7%, and 70.6% in MP <33%, MP 33%-39%, and MP > 40% groups, respectively (P < .001). The optimal MP cutoff of 36.5% distinguished pediatric CP patients with HH from those without HH with a sensitivity of 78%, specificity of 68%, a positive predictive value of 56.0%, and a negative predictive value of 85.2%, respectively. The application of MP and the severity of hip displacement, which can be easily measured by simple radiography, may be useful and reliable in screening for detecting HH in children with CP. Retrospectively registered. This study was approved by the Institutional Review Board of Seoul National University Bundang Hospital (IRB No. B-2007-627-106).

Abstract
Background and study aims The endoscopic pressure study integrated system (EPSIS), a novel diagnostic tool for gastroesophageal reflux disease (GERD), allows evaluation of the anti-reflux barrier using endoscopy by monitoring the intragastric pressure (IGP) during insufflation. In this study, we evaluated the association between EPSIS results and lower esophageal sphincter (LES) function measured by high-resolution manometry (HRM) to elucidate whether EPSIS can evaluate the LES function. Patients and methods A retrospective, single-center study of patients with GERD symptoms who underwent endoscopy, pH-impedance monitoring, EPSIS, and HRM was conducted. The primary outcome was basal LES pressure and the secondary outcomes were end-respiratory LES pressure and integrated relaxation pressure (IRP). As EPSIS parameters, the following were measured: 1) pressure difference (mmHg), the difference between maximum and basal IGP; and 2) pressure gradient (mmHg/s), calculated by dividing pressure difference by the insufflating time. Pressure difference < 4.7 mmHg or pressure gradient < 0.07 mmHg/s was defined as an EPSIS GERD pattern. Results Forty-seven patients (median age: 53 years, 37 female) were analyzed. Pressure difference and pressure gradient significantly correlated with basal LES pressure (ρ = 0.29; P = 0.04 and ρ = 0.29; P = 0.04). Patients with EPSIS GERD pattern showed significantly lower basal LES pressure [13.2 (4.8-26.6) vs 25.3 (10.4-66.7) mmHg, P = 0.002], lower end-respiratory LES pressure [8.5 (1.1-15.9) vs 15.5 (1.9-43.9) mmHg, P = 0.019] and lower IRP [5.9 (1.0-12.0) vs 9.8 (1.3-17.8) mmHg, P = 0.020]. Conclusions This study showed a close association between EPSIS results and LES pressures measured by HRM. This indicates that EPSIS can evaluate the LES function during endoscopy and endorse the role of EPSIS as a diagnostic tool for GERD.

Abstract
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 (Dmin) 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 Dmin (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 Dmin 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.

Abstract
Gastroesophageal reflux (GOR) is defined as "the passage of gastric contents into the esophagus with or without regurgitation and vomiting" and gastroesophageal reflux disease (GORD) is defined "when GOR leads to troublesome symptoms affecting the daily functioning and/or complications." This definition was first developed in 2006 by the Montreal consensus group (1) and later on adopted by pediatric gastroenterology societies such as ESPGHAN and NASPGHAN in 2009 (2). The definition of gastroesophageal reflux reveals little about its pathophysiology and is focused on symptomatology. In this way, it acts as an umbrella term for the multifactorial causes of the disease and the various phenotypes encountered; from functional heartburn to hypersensitive esophagus and nonerosive reflux disease, to erosive esophagitis and Barrett's esophagus. This article is devoted to the pathophysiology of pediatric GORD in comparison to adult GORD and is divided in 2 parts. In the first part, we will systematically describe the different mechanisms for the generation and clearance of reflux events, while on the second part we will discuss the mechanisms involved in symptoms generation. Finally, we will discuss the similarities and differences between pediatric and adult GORD.

Abstract
BACKGROUND Hiatal hernia is clinically important because it impairs the protective mechanism that prevents gastroesophageal reflux-induced injury. Diagnosing hiatal hernia is more important in neurologically impaired children because hiatal hernia-induced gastroesophageal reflux often causes severe complications such as aspiration pneumonia or malnutrition. We aimed to evaluate the patient characteristics and early predictors of hiatal hernia in neurologically impaired children. METHODS We retrospectively investigated 97 neurologically impaired children who underwent esophagogastroduodenoscopy and upper gastrointestinal series between March 2004 and June 2019. Demographic and clinical characteristics, as well as endoscopic and radiological findings, were statistically analyzed. RESULTS Of the 97 children recruited, 22 (22.7%) had hiatal hernia. When comparing the non-hiatal hernia group with the hiatal hernia group, neurological disease longer than 6 months (odds ratio 10.9, 95% confidence interval 1.2-96.5), wasting (odds ratio 4.6, 95% confidence interval 1.3-16.3), enteral tube feeding (odds ratio 9.2, 95% confidence interval 1.6-53.0), and history of aspiration pneumonia (odds ratio 6.5, 95% confidence interval 1.2-34.5) were identified as early predictors of hiatal hernia. CONCLUSIONS Timely identification of predictors of developing hiatal hernia in neurologically impaired children is important for early diagnostic confirmation to initiate optimal medical or surgical treatment of hiatal hernia to avoid serious complications such as aspiration pneumonia and malnutrition.

[PMID: 34874494 PMCID: PMC8977262 DOI: 10.1007/s11604-021-01210-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Accepted: 10/11/2021] [Indexed: 11/30/2022]
Abstract
Purpose To assess the esophagogastric junction (EGJ) on real-time MRI and compare imaging parameters to EGJ morphology on high-resolution manometry (HRM). Methods A total of 105 of 117 eligible patients who underwent real-time MRI and high-resolution manometry for GERD-like symptoms between 2015 and 2018 at a single center were retrospectively evaluated (male n = 57; female n = 48; mean age 52.5 ± 15.4 years). Real-time MRI was performed at a median investigation time of 15 min (1 frame/40 ms). On HRM, EGJ morphology was assessed according to the Chicago classification of esophageal motility disorders. Real-time MRI was performed at 3 T using highly undersampled radial fast low-angle shot acquisitions with NLINV image reconstruction. A 10 mL pineapple juice bolus served as oral contrast agent at supine position. Real-time MRI films of the EGJ were acquired during swallowing events and during Valsalva maneuver. Anatomic and functional MRI parameters were compared to EGJ morphology on HRM. Results On HRM, n = 42 patients presented with EGJ type I (40.0%), n = 33 with EGJ type II (31.4%), and n = 30 with EGJ type III (28.6%). On real-time MRI, hiatal hernia was more common in patients with EGJ type III (66.7%) than in patients with EGJ type I (26.2%) and EGJ type II (30.3%; p < 0.001). Sliding hiatal hernia was more frequent in patients with EGJ type II (33.3%) than in patients with EGJ type III (16.7%) and EGJ type I (7.1%; p = 0.017). The mean esophagus–fundus angle of patients was 85 ± 31° at rest and increased to 101 ± 36° during Valsalva maneuver. Conclusion Real-time MRI is a non-invasive imaging method for assessment of the esophagogastric junction. Real-time MRI can visualize dynamic changes of the EGJ during swallowing events.

THE KOREAN JOURNAL OF GASTROENTEROLOGY 2021; 76:134-141. [PMID: 32969361 DOI: 10.4166/kjg.2020.76.3.134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 05/25/2020] [Accepted: 06/04/2020] [Indexed: 11/03/2022]
Abstract
Background/Aims A diagnosis of gastroesophageal reflux disease is challenging in patients who have reflux symptoms but do not respond to proton pump inhibitors nor have reflux esophagitis and hiatal hernia (HH) on endoscopy. This study examined the predictive role of the endoscopic findings, including the flap valve grade for pathologic acid exposure (PAE) to establish an endoscopic prediction model in patients with neither reflux esophagitis nor HH. Methods Five hundred seventy-eight patients who underwent upper endoscopy and 24 hours pH monitoring for reflux esophageal symptoms without evidence of reflux esophagitis and HH were analyzed. The gastroesophageal flap valve (GEFV), esophageal metaplasia, and chronic atrophic gastritis were assessed. The association between the endoscopic parameters and PAE was evaluated. Results Four hundred ninety-four patients were enrolled. The most common complaint was chest discomfort (42.3%) followed by globus (31.8%), dysphagia (7.9%), and heartburn (7.7%). PAE was present in 43 patients (8.7%). Multivariable analysis revealed PAE to be associated with the GEFV grade (p<0.001) and inversely associated with the chronic atrophic gastritis grade (p=0.005). Using these features, a predictive model was established and showed an area under the receiver operating characteristic curve of 0.705 (95% CI 0.619-0.790). The cutoff value of 12.0 had a sensitivity and specificity of 44.0% and 84.0%, respectively. Conclusions A loosened GEFV is associated with a risk of PAE in patients with neither reflux esophagitis nor HH, while atrophic gastritis is preventive. On the other hand, the endoscopic predictive model revealed a low sensitivity for detecting PAE. Thus, reflux testing needs to be performed further when gastroesophageal reflux disease is suspected, even without endoscopic evidence.

Abstract
Gastroesophageal reflux disease (GERD) is steadily increasing in incidence and now affects 18% to 28% of the population in the United States. A thorough understanding of the pathophysiology underlying this disease is necessary to improve the current standard of care. Most GERD pathophysiology models focus on the lower esophageal sphincter (LES) as the key element which prevents esophageal reflux. More recent research has highlighted the crural diaphragm (CD) as an additional critical component of the GERD barrier. We now know that the CD actively relaxes when the distal esophagus is distended and contracts when the stomach is distended. Crural myotomy in animal models increases esophageal acid exposure, highlighting the CD's vital role. There are also multiple physiological studies in patients with symptomatic hiatal hernia that demonstrate CD dysfunction is associated with GERD. Finally, computer models integrating physiological data predict that the CD and the LES each contribute roughly 50% to the GERD barrier. This more robust understanding has implications for future procedural management of GERD. Specifically, effective GERD management mandates repair of the CD and reinforcement of the LES. Given the high rate of hiatal hernia recurrences, it seems that novel antireflux procedures should target this essential component of the GERD barrier. Future research should focus on methods to maintain crural integrity, decrease hiatal hernia recurrence, and improve long-term competency of the GERD barrier.

Abstract
The need for an antireflux procedure during repair of a paraesophageal hernia (PEH) has been the subject of a long-standing controversy. With most centers now performing routine fundoplication during PEH repair, high-quality data on whether crural repair alone or using a mesh may provide adequate anti-reflux effect is still scarce. We sought to answer to the question: "Is fundoplication routinely needed during PEH repair?". Our endpoints were (I) rates of postoperative gastroesophageal reflux disease (GERD) (either symptomatic or objectively assessed), (II) rates of recurrence, and (III) rates of postoperative dysphagia. We searched the MEDLINE, Cochrane, PubMed, and Embase databases for papers published between 1995 and 2019, selecting comparative cohort studies and only including papers reporting the rationale for performing or not performing fundoplication. Overall, nine papers were included for review. While four of the included studies recommended selective or no fundoplication, most of these data come from earlier retrospective studies. Higher-quality data from recent prospective studies including two randomized controlled trials recommended routine fundoplication, mostly due to a significantly lower incidence of postoperative GERD. However, only a relatively short follow-up of 12 months was presented, which we recognize as an important limitation. Fundoplication did not seem to result in reduced recurrence rates when compared to primary repair alone.

Abstract
BACKGROUND Gastric obstructions, leaks and staple line bleeding are reported after laparoscopic sleeve gastrectomy (LSG). There is no ideal method or technique to avoid these mishaps. We added modified omentopexy (OP) to LSG to determine if there is any effect on gastric leaks and some other complications. METHODS This single institution case control study included two groups of morbidly obese patients undergoing LSG. They were grouped as omentopexy (OP) or no omentopexy (NP). Patient characteristics such as age, sex, ASA (American Society of Anesthesiologists) risk, body mass index (BMI), nutritional status and comorbidities were comparable. Postoperative follow-up was scheduled at 1 week, 1 month, 3 months, 6 months and 12 months. All received standard postoperative clinical, nutritional evaluation and PPI therapy for at least 3 months. RESULTS Total 737 patients underwent LSG from January 2012 to December 2017. Out of these, 370 that had OP and 367 that had NP were analyzed. NP group was subdivided into Lemberted Staple line (LS) and bioabsorbable staple line reinforcement (BSLR) groups. Gastric leaks and perforations were clubbed together as gastric disruptions (GD). Patients with at least 15 months of postoperative follow-up were included. Those who failed to follow up were excluded. GD was reported in 7 out of 367 NP patients (1.9%), while no GD was seen in 370 OP patients (P = 0.01). Bleeding was seen in 1 OP versus 2 NP patients (P = 0.6). Venous thromboembolism was reported in 2 OP versus 1 NP patients (P = 1). Wound infection was seen in 1 OP versus 2 NP patients (P = 0.6). Readmissions were noted in 2 OP versus 6 NP patients (P = 0.1). Pneumonia was seen in 2 OP and 2 NP patients (P = 1). Postoperative dehydration was seen in zero OP versus 1 NP patients (P = 0.4). Gastric obstruction was not seen in any of the patients. Postoperative gastric reflux was present in 49/370(13.2%) OP versus 57/367(15.4%) NP patients (P = 0.4). Within NP group, LS (Lemberting of Staple line) patients (286/367) had 4 GD (1.39%) versus no GD in OP (P = 0.03). BSLR (Bioabsorbable Staple line re-enforcement) patients (81/367) had 3 GD (3.7%) versus no GD in OP (P = 0.005). None of the groups had any mortality. CONCLUSIONS GD (gastric disruptions) were statistically significant, but the following bleeding, venous thromboembolism and gastroesophageal reflux did not reach statistical significance, which indicates that OP, if performed correctly with LSG, has favorable effects on gastric leaks.

Abstract
BACKGROUND The mechanisms associated with gastro-esophageal reflux (GER) episodes were studied using combined High-resolution Impedance Manometry (HRIM) and pH monitoring in ambulant subjects with different patterns of GERD. METHODS Sixteen subjects with mild-moderate esophagitis (Los Angeles (LA) grade A&B) (group A) and 11 subjects with severe esophagitis (LA grade C&D) or Barrett's esophagus (BE) were studied before and after a meal, resting, while walking, and during standardized exercise, using a HRIM and a pH probe. KEY RESULTS Post-prandial acid GER episodes were more common in group B (median 10 range (3-18) vs A (6.5 (0-18), p = 0.048). Postprandial acid clearance time was much longer in group B (median 0.71( 0.07-2.66 min) vs A (0.17 (0.04-2.44 min), p = 0.02). Transient lower esophageal sphincter relaxation (TLESR) was the most frequent mechanism associated with GER episodes in both groups. Post-prandial TLESRs with GER were more common in group B (median 17 (9-24) vs A 13.5 (7-34), p = 0.014), particularly during exercise (B 8 (6-9) vs A 6 (5-6.8), p = 0.007). Post-prandially TLESR with acid reflux increased during exercise in both groups (A rest median 2.4 (0-6.4) per hour vs exercise 4.7 (0-17.3), p = 0.005 and B 4 (0.8-9.6) vs 5.3 (2.7-13.3) per hour, p = 0.045). CONCLUSIONS AND INFERENCES TLESR was the most common mechanism associated with reflux episodes in all subjects. Acid reflux episodes were more common in subjects with severe esophagitis or BE and esophageal acid clearance was much slower. Post-prandial exercise increased TLESR with acid reflux and GERD patients should be encouraged to avoid exercise immediately after a meal.

Abstract
OBJECTIVES Esophageal variceal bleeding can be fatal in patients with liver cirrhosis. The aim of this study was to investigate the relationship between gastroesophageal flap valve (GEFV) and esophageal variceal bleeding. METHODS Subjects were cirrhotic patients with endoscopically diagnosed esophageal varices treated at our hospital between 2005 and 2019, excluding those with F3 form and red color (RC) signs at first endoscopy. Sixty-five patients with normal GEFV (Hill grade I or II) and 42 with abnormal GEFV (Hill grade III or IV) were enrolled. Propensity score matching eliminated the baseline differences, resulting in a sample size of 30 patients per cohort. The primary endpoint was esophageal variceal bleeding, and the secondary endpoint was variceal bleeding or appearance of RC sign. We analyzed the cumulative incidences and predictors of each endpoint. RESULTS The 3-, 5-, and 10-year cumulative incidences of the primary endpoints were all 3.4% in the normal GEFV group, and 19.0%, 24.6% and 34.0% in the abnormal GEFV group, respectively (log-rank P = 0.011). Cumulative incidence of the secondary endpoint was 13.8%, 33.1% and 39.2% in the normal GEFV group, and 42.2%, 54.6% and 84.9% in the abnormal GEFV group, respectively (log-rank P = 0.001). In multivariate Cox regression analyses, hazard ratios of abnormal GEFV of the primary and secondary endpoints were 12.79 (95% confidence interval 1.331-122.8) and 3.600 (1.653-7.840), respectively. CONCLUSIONS Abnormal GEFV was an independent risk factor for esophageal variceal bleeding and appearance of RC sign.

Abstract
OBJECTIVE To determine whether an anatomical difference in esophageal hiatus (EH) size exists between brachycephalic and nonbrachycephalic dogs. STUDY DESIGN Retrospective clinical study. ANIMALS Client-owned dogs (n = 87). METHODS Clinical records and images of dogs that underwent computed tomography between June 2015 and September 2018 were reviewed. For the first part of the study, EH and aortic (Ao) cross-sectional surface areas were measured in brachycephalic (group 1) and nonbrachycephalic dogs of similar body size (<15 kg) without respiratory or gastroesophageal (GE) signs (group 2) by using multiplanar reconstruction. Esophageal hiatus:aortic ratio was calculated. In the second part of the study, absolute EH measurements were also compared in weight-matched (WM) dogs (8-10 kg) from groups 1 and 2. RESULTS Mean (±SD) of EH:Ao values for group 1 (8.1 ± 2.8) were higher (P < .0001) than those for group 2 (3.7 ± 1.1). In addition, EH measurements of 20 WM dogs in group 1 were higher than those of 20 dogs in group 2 (P < .05). CONCLUSION Esophageal hiatus cross-sectional surface area (directly and indirectly measured) in brachycephalic dogs was considerably larger than that in nonbrachycephalic dogs of generally similar body size. CLINICAL SIGNIFICANCE Results of this study provide evidence to support the existence of a specific anatomical factor that could likely correlate to functional GE alterations (eg, regurgitation, gastroesophageal reflux, and sliding hiatal hernia) commonly seen in brachycephalic dogs.

Abstract
Patients with esophageal symptoms potentially associated with gastroesophageal reflux disease such as heartburn, regurgitation, chest pain, or cough represent one of the most frequent reasons for referral to gastroenterological evaluation. The utility of esophageal reflux monitoring in clinical practice is: (1) to accurately define reflux burden, (2) to segregate patients according to reflux monitoring results as true GERD, reflux hypersensitivity and functional heartburn, and (3) to establish a treatment plan. With this in mind, in the last decade, investigations and technical advances, with the introduction of impedance-pH monitoring and wireless pH capsule, have enhanced our understanding and management of GERD. The following recommendations were discussed and approved after a comprehensive review of the medical literature pertaining to reflux testing techniques and their recent application. This review created under the auspices of the Società Italiana di Gastroenterologia ed Endoscopia Digestiva (SIGE), Società Italiana di Neuro-Gastro-Enterologia e Motilità (SINGEM) and Associazione Italiana Gastroenterologi ed Endoscopisti Digestivi Ospedalieri (AIGO) is intended to help clinicians in applying reflux studies in the most fruitful manner within the context of their patients with esophageal symptoms.

Abstract
BACKGROUND A proportion of patients with gastroesophageal reflux disease (GERD) do not respond to proton pump inhibitor (PPI) therapy. AIM OF THE STUDY To determine the findings on high-resolution esophageal manometry (HREM) and 24-h pH recording in patients with typical GERD symptoms, refractory to PPI treatment. METHODS Retrospective analysis of prospectively maintained database of patients referred for HREM and 24-h pH recording was done. We selected patients who were referred for evaluation of refractory GERD symptoms despite > 8 weeks of at least once-daily PPI treatment. Details noted were demographic profile, upper gastrointestinal endoscopy report, HREM findings and 24-h pH findings. RESULTS Ninety-six patients had symptoms of GERD that were refractory to PPI therapy. Seven patients (7.1%) were diagnosed having diseases mimicking GERD: eosinophilic esophagitis (n=2), supragastric belching (n=4) and rumination (n=1). After excluding these patients and those with insufficient data, the final study cohort included 82 cases. Fifty patients (61%) had normal motility. Major motility disorders were detected in 8 (9.75%) patients: achalasia cardia (6) and distal esophageal spasm (2). Ineffective esophageal motility was noted in 24 patients. A total of 74 patients underwent 24-h pH testing. Significant acid reflux with good symptom correlation was noted in 56 patients. Eighteen patients did not have significant acid reflux (Johnson-DeMeester score < 14.7): hypersensitive esophagus (12) and functional heartburn (6). CONCLUSION Fifty-six patients (68.3%) had definite diagnosis of GERD and 31.7% (26) had non-GERD conditions like motility disorders, functional heartburn and hypersensitive esophagus.

Abstract
Objectives The role of gastroesophageal reflux disease (GERD) in the aetiology of laryngopharyngeal reflux (LPR) is poorly understood and remains a controversial issue. The 24-hour impedance monitoring has shown promise in the evaluation of LPR but is problematic in pharyngeal recording. We have shown the utility of scintigraphic studies in the detection of LPR and lung aspiration of refluxate. Correlative studies were obtained in patients with a strong history of LPR and severe GERD. Methods A highly selected sequential cohort of patients with a high pre-test probability of LPR/severe GERD who had failed maximal medical therapy were evaluated with 24-hour impedance/pH, manometry and scintigraphic reflux studies. Results The study group comprised 34 patients (15 M, 19 F) with a mean age of 56 years (range: 28-80 years). The majority had LPR symptoms (mainly cough) in 31 and severe GERD in 3. Impedance bolus clearance and pH studies were abnormal in all patients in the upright and supine position. A high rate of non-acid GERD was detected by impedance monitoring. LOS tone and ineffective oesophageal clearance were found in the majority of patients. Scintigraphic studies showed strong correlations with impedance, pH and manometric abnormalities, with 10 patients showing pulmonary aspiration. Conclusion Scintigraphic studies appear to be a good screening test for LPR and pulmonary aspiration as there is direct visualisation of tracer at these sites. Impedance studies highlight the importance of non-acidic reflux and bolus clearance in the causation of cough and may allow the development of a risk profile for pulmonary aspiration of refluxate.

Abstract
BACKGROUND Chronic gastroesophageal reflux predisposes to the development of esophageal adenocarcinoma (EAC). Asthma and medication to treat it are associated with gastroesophageal reflux and EAC. We studied subjects with chronic obstructive pulmonary disease (COPD) to examine the relationship between COPD and medication used to treat it, and the risk of reflux esophagitis, Barrett's esophagus, and EAC. METHODS A case-control study from the UK General Practice Research Database was conducted. Cases were aged 50 or above with a diagnosis of COPD and were matched with controls without a diagnosis of COPD by age, general practitioners practice, and time on the database. EAC was confirmed by cross-referencing cancer registry data. Cox-regression analysis was performed to assess the relationship between COPD, reflux esophagitis, Barrett's esophagus, and EAC. RESULTS A total of 45,141 cases were studied [24,464 male, age 75 (50 to 100) years]. Among COPD cases there were 55 esophageal cancers (30 EAC) and 506 Barrett's esophagus, compared with 62 (34 EAC) and 329 Barrett's esophagus among controls. COPD was not associated with EAC on univariable [0.92 (0.56 to 1.50), P=0.73] and multivariable analysis [0.85 (0.52 to 1.40), P=0.53]. COPD was however, associated with Barrett's esophagus on univariable [0.92 (0.56 to 1.50), P=0.73] and multivariable [1.53 (1.31 to 1.78), P<0.001] analysis and reflux esophagitis on univariable [1.41 (1.36 to 1.48), P<0.001] and multivariable [1.33 (1.27 to 1.40), P<0.001] analysis. CONCLUSION COPD is associated with an increased risk of reflux esophagitis and Barrett's esophagus but not EAC.

Abstract
BACKGROUND Diaphragmatic and hiatus hernias can cause mild chronic symptoms or have an acute presentation with gastric volvulus and obstruction. Elective or emergency surgery is indicated in symptomatic patients and nowadays is generally performed laparoscopically. METHODS We report four different types of hernias: a giant hiatus hernia following a gastric pull-up for recurrent congenital diaphragmatic hernia; a Bochdalek hernia in a pregnant young woman; concomitant hiatus and Morgagni hernias; and a giant hiatus hernia occupying the right chest. All were approached laparoscopically, either electively or as an emergency. RESULTS Surgery led to a resolution of symptoms in all the cases. We had no any intraoperative complications. Two patients developed minor postoperative complications (chest infection). No recurrences were found during a mean follow-up of 18 months. CONCLUSIONS Transabdominal laparoscopic approach is a safe and feasible approach to all cases of symptomatic hiatus and diaphragmatic hernia.

Abstract
Manometry and 24-h pH interpretation have seldom been studied. Our aim was to study these parameters as gold standard in reflux disease and to identify predictors of pathological acid reflux. Retrospective case record review of all patients with reflux disease evaluated using endoscopy, manometry, and 24-h pH testing from 2010 to 2016. Patients were categorized using Johnson-DeMeester score into two groups-group I (score > 14.7, normal study) and group II (< 14.7, normal study). These groups were compared for the above-mentioned parameters. Appropriate statistical tests were applied. P-value < 0.05 was considered significant. The study group includes 94 patients (median age 44 years, 63.8% males). Sixty (63.8%) and 34 patients belonged to groups I and II, respectively, 76.6% patients had normal endoscopy while the remaining had mild esophagitis. Peristalsis was normal in 66%, followed by ineffective esophageal motility (19.1%) and fragmented peristalsis (14.9%). Demography, symptoms, endoscopy findings, and peristalsis characteristics were similar between the two groups. Group II patients had significantly lower basal lower esophageal sphincter (LES) pressure (11.9 vs. 16.6; p < 0.02), lower integrated relaxation pressure (5.7 vs. 7.4; p < 0.01), and larger separation between LES and crural diaphragm (1.7 vs. 1.4 cm; p < 0.003). Basal LES pressure < 10 mmHg had the highest likelihood ratio (2.2) to predict an abnormal pH study. Basal LES pressure, integrated relaxation pressure, and hiatus size correlated with pathological acid reflux. Hypotensive basal lower esophageal sphincter pressure was the best predictor of an abnormal pH study but with negative linear correlation.

Abstract
Background Previous studies suggest clinical effectiveness of endoscopic full-thickness plication in selected patients with gastroesophageal reflux disease (GERD). The aim of this study was to assess the clinical safety and efficiency of the GERDx™ device by evaluating clinical parameters, reflux symptom scores, and quality of life (QoL). Methods Prospective one-arm trial evaluating the outcome of forty patients with GERD subjected to endoscopic plication with the GERDx™ device. We included patients with at least one typical reflux symptom despite treatment with a PPI for > 6 months, pathologic esophageal acid exposure, hiatal hernia of size < 2 cm, and endoscopic Hill grade II–III. Evaluation of Gastrointestinal Quality of Life Index (GIQLI), symptom scores, esophageal manometry, and impedance-pH-monitoring were performed at baseline and at 3 months after surgery. (Trial Registration: ClinicalTrials.gov NCT 01798212.) Results There were no intraoperative complications. Four out of forty patients experienced postoperative complications requiring intervention. Seven of forty patients were subjected to laparoscopic fundoplication 3 months after endoscopic plication due to persistent symptoms and were lost to further follow-up. Thirty out of forty patients were available at 3-month follow-up. There was an improvement of the GIQLI score, from a mean of 92.45 ± 18.47 to 112.03 ± 13.11 (p < 0.001). The general reflux-specific score increased from a mean of 49.84 ± 24.83 to 23.93 ± 15.63 (p < 0.001), and the DeMeester score from a mean of 46.48 ± 30.83 to 20.03 ± 23.62 (p < 0.001). There was no significant change in manometric data after intervention. Three of thirty patients continued daily antireflux medication. Conclusions Endoscopic plication with the GERDx™ device reduced distal acid exposure of the esophagus, reflux-related symptoms, and improved GIQLI scores with minimal side effects in a selected cohort of patients and may be a safe alternative in the treatment of GERD.

Abstract
Magnetic sphincter augmentation is a novel surgical procedure for gastroesophageal reflux disease. Limited dissection at the hiatus is one of the benefits of the procedure, but makes precise and accurate preoperative assessment of even small hiatal hernia critical. Retrospective cohort study of 136 patients having undergone both endoscopy (EGD) and videoesophagography followed by operative assessment for hiatal hernia during magnetic sphincter augmentation. The objective of the study is to determine which preoperative modality more accurately predicts operative hiatal hernia size. Videoesophagography underestimated operative measurement by 0.37 ± 1.41 cm ( P = 0.003) and was less accurate in predicting intraoperative hiatal hernia size than EGD on linear regression analysis (β -0.729, SE 0.057, P < 0.001). EGD was less accurate at predicting hiatal hernia size as patient age increased (β -0.018, SE 0.007, P = 0.014) and with larger hernias (β -0.615, standard error (SE) 0.067, P < 0.001); however, endoscopic measurements did not differ significantly from intraoperative measurements (0.93 ± 1.23 cm vs 1.12 ± 1.43 cm, P = 0.12). EGD better predicts the size of small hiatal hernia measured during subsequent laparoscopic surgery.

Abstract
Exercise-inducible laryngeal obstruction (EILO) has been recognized as a not rare respiratory problem in youth practicing sports. The aim of the study was to test the mechanosensitivity of the larynx, and to identify the factors affecting it in a group of youth with proven EILO. Laryngeal sensory testing was performed in 54 adolescents and young adults with EILO. Laryngeal mucosal alterations were assessed according to the Reflux Finding Score (RFS). The data concerning diseases possibly affecting the upper airway, findings of previously performed flexible videolaryngoscopy during exercise, and RFS score were compared between the participants with laryngeal hyposensitivity and those with normal sensitivity. The participants with isolated vocal folds' adduction during an EILO attack were compared with those who demonstrated supraglottis collapse. Testing revealed an increased threshold for mechanical stimuli in 81.5% of participants. Among participants with hyposensitivity, there were significantly more participants with dysphagia during EILO attacks than among the participants with normal laryngeal sensitivity. The hyposensitivity group had a significantly higher RFS score compared with the other group. Isolated vocal folds' approximation was only observed in 11.9% of participants. These participants were younger and had asthma more frequently compared with the others. Only 16.9% of participants with EILO did not state symptoms related to gastroesophageal reflux. The decreased mechanosensitivity was detected in the majority of participants, suggesting that laryngopharyngeal reflux can be an important etiological factor. The problem of breathing difficulties during sport activities in youth can also be associated with the disproportionate growth of the respiratory tract.

Abstract
The pathogenesis of gastroesophageal reflux disease (GERD) is complex and involves changes in reflux exposure, epithelial resistance, and visceral sensitivity. The gastric refluxate is a noxious material that injures the esophagus and elicits symptoms. Esophageal exposure to gastric refluxate is the primary determinant of disease severity. This exposure arises via compromise of the anti-reflux barrier and reduced ability of the esophagus to clear and buffer the refluxate, leading to reflux disease. However, complications and symptoms also occur in the context of normal reflux burden, when there is either poor epithelial resistance or increased visceral sensitivity. Reflux therefore develops via alterations in the balance of aggressive and defensive forces.

Abstract
BACKGROUND To determine the correlation between asthma and hiatal hernia (HH) in patients with gastroesophageal reflux disease (GERD)-related asthma requiring laparoscopic anti-reflux surgery. METHODS One hundred and thirty-six GERD patients with medically refractory asthma with (80 patients) or without HH (56 patients) were enrolled. Gastroesophageal reflux disease was assessed by endoscopy, esophageal manometry, reflux monitoring and symptom questionnaires, and treated with laparoscopic Nissen fundoplication (LNF) or LNF with concomitant hiatal hernia repair (LNF-HHR). The outcome measures included patients' satisfaction and drug independence. RESULTS The patients with HH had lower esophageal sphincters (P = .005) and higher DeMeester scores (P = .014) than those without HH. After an average follow-up of 24 months, symptom scores were significantly decreased from the preoperative values (P < .05). Compared to LNF, LNF-HHR showed a better improvement in both esophageal and asthmatic symptoms (P < .0001 and P = .016, respectively). CONCLUSIONS The patients with GERD with asthma have a high prevalence of HH. The presence of HH maybe correlated with asthma and severe GERD. Actively treating HH not only improved reflux, but also controlled asthma symptoms.

Abstract
Gastro-oesophageal reflux disease (GORD) develops when reflux of gastric content causes troublesome symptoms or complications. The main symptoms are heartburn and acid regurgitation and complications include oesophagitis, strictures, Barrett's oesophagus and oesophageal adenocarcinoma. In addition to hereditary influence, GORD is associated with lifestyle factors, mainly obesity. Tobacco smoking is regarded as an aetiological factor of GORD, while alcohol consumption is considered a triggering factor of reflux episodes and not a causal factor. Yet, both tobacco smoking and alcohol consumption can reduce the lower oesophageal sphincter pressure, facilitating reflux. In addition, tobacco smoking reduces the production of saliva rich in bicarbonate, which is important for buffering and clearance of acid in the oesophagus. Alcohol also has a direct noxious effect on the oesophageal mucosa, which predisposes to acidic injury. Tobacco smoking cessation reduces the risk of GORD symptoms and avoidance of alcohol is encouraged in individuals where alcohol consumption triggers reflux.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is becoming the most performed bariatric procedure; however, data available on long-term follow-up are scanty. OBJECTIVES The aim of the present study was to evaluate the 5-year efficacy of LSG on weight loss, gastroesophageal reflux disease (GERD) symptoms, and obesity-associated co-morbidities. SETTING Tertiary-care referral hospital. METHODS This study retrospectively analyzed 105 obese patients undergoing LSG from January 2006 to December 2009. The preoperative evaluation included demographic characteristics, evaluation of co-morbidities, a double-contrast barium swallow, and an upper-gastrointestinal endoscopy. The following data were collected at 1, 3, and 5 years after surgery: weight, improvement/remission of co-morbidities, complications, and revisional surgery. RESULTS According to preoperative body mass index (BMI), patients were divided into Group 1 (n = 61) with BMI≤50 kg/m(2) and Group 2 (n = 44) with BMI>50 kg/m(2). The follow-up rate was 94% after 5 years (n = 99). Delta BMI (BMI at follow-up-preoperative BMI) was significantly higher in Group 2 than in Group 1 at 1-3 years and 5 years (P<.001). Furthermore, at 5 years, Group 2 showed a significantly higher percentage total weight loss (%TWL) (26.6%±18.3% versus 33.5%±12.9%, P = .006) than Group 1, whereas percentage excess weight loss was similar (58.4%±21.8% versus 55.3%±19.5%, P = .5).Younger age at surgery and absence of postoperative GERD were associated with a better %TWL at 5 years (P<.001 and P = .03). CONCLUSION LSG is an effective procedure at long-term, with good weight loss outcomes and with a considerable improvement of obesity-associated co-morbidities. Younger age at surgery and absence of postoperative GERD were associated with a better %TWL at 5 years.

Abstract
Case summary A 10-month-old domestic shorthair cat was evaluated for severe esophagitis and protracted vomiting and regurgitation secondary to a sliding (type I) hiatal hernia. The hernia and concurrent upper airway obstruction (nasopharyngeal polyp) were diagnosed with a multi-modality approach, including thoracic and abdominal radiographs, abdominal ultrasound, computed tomography and endoscopy. Following unsuccessful attempts at medical management, lower esophageal incompetence was successfully treated by employing a combination of surgical techniques, including herniorrhaphy, esophagopexy and modified (floppy) Nissen fundoplication. Relevance and novel information A multi-modality imaging approach was valuable in completely assessing the extent of this cat’s disease. Although an untraditional approach, the authors report herein the first clinical description of the use of combined surgical techniques with the floppy Nissen fundoplication technique (an antireflux procedure) in a cat. This procedure was used as a first-line surgical technique in this cat with severe lower esophageal incompetence, and may be a viable option for cases non-responsive to other therapeutic interventions. Further investigation of this surgical technique is warranted.

Abstract
BACKGROUND Accurate measurement of esophageal hiatus size is clinically important, especially when antireflux surgery is planned. We present a novel method for in vivo measurement of esophageal hiatal surface area using MDCT multiplanar reconstruction. We aimed to determine whether large hiatal area is associated with hiatal hernia and gastroesophageal reflux disease. METHODS We retrospectively analyzed subjects prospectively enrolled in the COPDGene(®) project. We created two test groups, one with hiatal hernia on chest CT and one with GERD on medical treatment identified by history without hernia. Matched control groups were formed. We performed CT postprocessing to define the double-oblique plane of the esophageal hiatus, on which the hiatal surface area is manually traced. RESULTS Subjects with hernia (n = 48) had larger mean hiatus areas than matched controls (6.9 vs. 2.5 cm(2), p < 0.0001), and were more likely to have GERD (42 vs. 10 %, p < 0.0005). Subjects with mixed (type III) hernias had larger hiatuses compared to subjects with sliding (type I) hernias, who, in turn, had larger hiatuses than subjects without hernia (p < 0.0001). Hernia-negative subjects with GERD (n = 55) did not have significantly larger mean hiatal areas compared to matched controls (3.0 vs. 2.5 cm(2), p = 0.12). Twenty measurements obtained by two radiologists showed correlation of 0.93, with mean difference of 0.5 cm(2) (p = 0.20). CONCLUSIONS We devised a method to measure in vivo esophageal hiatal surface area using MDCT reconstruction and established the normal size range for the first time. This methodology has the potential to guide decision-making in antireflux surgery technique preoperatively, and assess surgical result postoperatively. The presence of hernia correlated with large hiatuses and GERD. However, hiatal area failed to identify those with GERD in the absence of hiatal hernia.

Abstract
The worldwide incidence of GORD and its complications is increasing along with the exponentially increasing problem of obesity. Of particular concern is the relationship between central adiposity and GORD complications, including oesophageal adenocarcinoma. Driven by progressive insight into the epidemiology and pathophysiology of GORD, the earlier belief that increased gastroesophageal reflux mainly results from one dominant mechanism has been replaced by acceptance that GORD is multifactorial. Instigating factors, such as obesity, age, genetics, pregnancy and trauma may all contribute to mechanical impairment of the oesophagogastric junction resulting in pathological reflux and accompanying syndromes. Progression of the disease by exacerbating and perpetuating factors such as obesity, neuromuscular dysfunction and oesophageal fibrosis ultimately lead to development of an overt hiatal hernia. The latter is now accepted as a central player, impacting on most mechanisms underlying gastroesophageal reflux (low sphincter pressure, transient lower oesophageal sphincter relaxation, oesophageal clearance and acid pocket position), explaining its association with more severe disease and mucosal damage. Since the introduction of proton pump inhibitors (PPI), clinical management of GORD has markedly changed, shifting the therapeutic challenge from mucosal healing to reduction of PPI-resistant symptoms. In parallel, it became clear that reflux symptoms may result from weakly acidic or non-acid reflux, insight that has triggered the search for new compounds or minimally invasive procedures to reduce all types of reflux. In summary, our view on GORD has evolved enormously compared to that of the past, and without doubt will impact on how to deal with GORD in the future.

Abstract
BACKGROUND The diagnosis of a sliding hiatal hernia is classically made with endoscopy or barium esophagogram. Spatial separation of the lower esophageal sphincter (LES) and diaphragm, the hallmark of hiatal hernia, can also be observed on high-resolution manometry (HRM), but the diagnostic accuracy of this finding has not yet been investigated. To determine the diagnostic value of HRM in the detection of hiatal hernia. METHODS HRM recordings, endoscopy reports, and barium esophagograms of 90 patients were analyzed for the presence and size of a hiatal hernia. The diagnostic value of a hernia specific HRM pressure pattern was calculated, and the agreement of HRM with endoscopy and barium esophagogram for the assessment of hernia size. KEY RESULTS HRM was found to be highly sensitive and specific for hiatal hernia detection, with a sensitivity of 92% and specificity of 95%, exceeding the sensitivity of endoscopy or radiography alone (both 73%). Patients with a hiatal hernia on HRM were manometrically characterized by an esophagogastric junction (EGJ) with partial or complete separation of the LES and crural diaphragm (CD), the latter being associated with significantly lower EGJ pressure. A cutoff value of spatial LES-CD separation on HRM of 1.85 cm yielded the optimal performance in identifying hiatal hernia. Agreement between HRM, endoscopy, and radiography for size of hiatal hernias was good (ICC [95% CI] 0.74 [0.65-0.82]). CONCLUSIONS & INFERENCES With HRM, the presence or absence and size of a hiatal hernia can be assessed with greater sensitivity than with endoscopy or radiography alone.

Abstract
BACKGROUND Esophageal acid retention in a hiatal hernia (HH) may play a role in gastro-esophageal reflux. The aims of this study were to determine the prevalence of bolus retention (BR) in HH and to compare pressure profiles in patients with HH with BR in the hernia to those with bolus clearance (BC) through the hernia using high-resolution esophageal manometry with impedance (HREMI). METHODS Clinical HREMI studies with HH ≥1.5 cm were analyzed for lower esophageal sphincter (LES) and crural diaphragm (CD) pressures and pressure profiles during 12 saline swallows. Impedance was analyzed for swallow retention in the HH. KEY RESULTS Bolus retention in a HH was present in 35 of 53 (66%) patients with a HH. Patients with BR had overall lower pressure profiles including a lower basal LES pressure (14.8 ± 10.6 vs 28.9 ± 16.8 mmHg; p = 0.0001), LES-CD gradient (6.8 ± 17.9 vs 20.6 ± 12.2 mmHg; p = 0.002), residual LES pressure (2.5 ± 4.6 vs 6.1 ± 12.2 mmHg; p = 0.017), amplitude of distal esophageal contractions (83.2 ± 38.8 vs 111.2 ± 42.8 mmHg; p = 0.020), and distal contractile integral (1487 ± 1016 vs 2608 ± 1221 mmHg-cm-sec; p = 0.001) compared to the BC group. Patients with BR were more likely to have a larger sized HH compared to the BC group (3.1 ± 1.6 vs 2.1 ± 0.6 cm; p = 0.016); similar pressure changes were found when the groups were divided up by HH sizes. CONCLUSIONS & INFERENCES Bolus retention was seen in 66% of patients with HH. Bolus retention in the HH was associated with larger HH size, lower LES pressure, and lower esophageal contractile pressures compared to those with BC.

Abstract
OBJECTIVES/HYPOTHESIS Ambulatory esophageal impedance monitoring is commonly employed to assess for nonacid reflux in patients with extraesophageal reflux. We aimed to determine if on therapy impedance data can be predicted from off therapy upper endoscopy, manometry, or pH parameters. STUDY DESIGN Prospective Cohort Study. METHODS Patients with extraesophageal reflux symptoms and either partial- or nonresponders to twice-daily PPI underwent impedance monitoring on twice-daily PPI, as well as manometry, upper endoscopy, and 48-hour wireless pH monitoring off acid-suppressive medications for 1 week. Percent time pH < 4 and number of reflux episodes were obtained. Multivariable linear regression was used to determine association between the impedance data on therapy and upper endoscopy, manometry, and pH parameters measured off therapy. RESULTS Seventy-five patients (77% female, median BMI 29, 38% with hiatal hernia, and 19% with esophagitis) were studied both on and off therapy. Thirty-five percent had abnormal impedance monitoring on therapy and 84% had abnormal pH testing off therapy. There was no significant (P = 0.184) overall correlation between total number of impedance events and the baseline physiologic parameters of hiatal hernia, degree of acid reflux, or manometric findings, with only weak correlation (r = 0.54, P = 0.045) with % time pH < 4 among patients with esophagitis. CONCLUSIONS In patients with suspected extraesophageal reflux refractory to PPI therapy, impedance measures on therapy cannot be predicted from traditional baseline esophageal physiologic parameters. We recommend caution regarding over-interpretation of impedance data. LEVEL OF EVIDENCE 2b.

Abstract
BACKGROUND Laparoscopic Nissen fundoplication is comprised of: a wrap thought responsible for the lower esophageal sphincter function and crural closure performed to prevent herniation. We hypothesized gastroesophageal junction competence effected by Nissen fundoplication results from closure of the crural diaphragm and creation of the fundoplication. METHODS Patients with uncomplicated reflux undergoing Nissen fundoplication were prospectively enrolled. After hiatal dissection, patients were randomized to crural closure followed by fundoplication (group 1) or fundoplication followed by crural closure (group 2). Intra-operative high-resolution manometry collected sphincter pressure and length data after complete dissection and after each component repair. RESULTS Eighteen patients were randomized. When compared to the completely dissected hiatus, the mean sphincter length increased 1.3 cm (p < 0.001), and mean sphincter pressure was increased by 13.7 mmHg (p < 0.001). Groups 1 and 2 had similar sphincter length and pressure changes. Crural closure and fundal wrap contribute equally to sphincter length, although crural closure appears to contribute more to sphincter pressure. CONCLUSION The Nissen fundoplication restores the function of the gastroesophageal junction and thus the reflux barrier by means of two main components: the crural closure and the construction of a 360° fundal wrap. Each of these components is equally important in establishing both increased sphincter length and pressure.

Abstract
Bariatric surgery, when combined with lifestyle and medical interventions, is a common and successful treatment modality in the obese patient. Laparoscopic sleeve gastrectomy is one such procedure that has increased in popularity as a definitive bariatric operation. Although laparoscopic sleeve gastrectomy has been shown to be effective in producing weight loss and improving type 2 diabetes mellitus, its effect on gastroesophageal reflux disease (GERD) has been inconsistent. This paper aims to summarize the available literature regarding GERD prevalence following laparoscopic sleeve gastrectomy, 8 studies demonstrate increased GERD prevalence, and 5 demonstrate decreased GERD prevalence following laparoscopic sleeve gastrectomy. The relationship between GERD and SG is complex and no clear relationship exists. The anatomic and physiologic changes caused by laparoscopic sleeve gastrectomy are discussed in the context of these inconsistent results.

Abstract
BACKGROUND Subjective and especially objective data after endoluminal full-thickness gastroplication are scarce. OBJECTIVE To evaluate symptoms and reflux activity 12 months after gastroplication by using multichannel intraluminal impedance monitoring. DESIGN Open-label, prospective, single-center study. SETTING Tertiary referral hospital in Zell am See, Austria. PATIENTS Subjects without hiatal hernias with documented GERD and persistent or recurrent symptoms despite treatment with a proton pump inhibitor. INTERVENTIONS A total of 36 patients underwent endoscopic full-thickness gastroplication with 1 or more Plicator implants. MAIN OUTCOME MEASUREMENTS Mean Gastrointestinal Quality of Life Index and reflux-specific symptom scores significantly improved on follow-up (P < .01). Atypical reflux, gas/bloating, and bowel dysfunction-specific symptom scores as well as belching and dysphagia scores improved. Twenty-two patients returned for esophageal manometry and multichannel intraluminal impedance testing 1 year after surgery. DeMeester scores decreased from 20 to 10 (P < .029). The median numbers of total, acid, proximal, upright, and recumbent reflux episodes were all significantly reduced (P < .05). Manometric data were virtually unchanged. The percentage of patients taking proton pump inhibitors on daily basis after the procedure was 11.5%. There was only 1 postprocedure incident (bleeding) that required intervention. Three of 36 patients (8.3%) were considered treatment failures because of persistent symptoms and were assigned to undergo laparoscopic fundoplication. LIMITATIONS No randomized comparison with a sham procedure or laparoscopic fundoplication; follow-up interval. CONCLUSIONS Endoscopic plication is safe and improves objective and subjective parameters at 1-year follow-up, without side effects seen after laparoscopic fundoplication. Further studies on the clinical merit of this procedure in specific patient populations are warranted.

Abstract
BACKGROUND & AIMS Radiofrequency ablation (RFA) is a safe alternative to esophagectomy for patients with dysplastic Barrett's esophagus (BE). Although some studies have indicated that RFA is effective at eradicating dysplasia, most have found that RFA is not as effective in eradicating intestinal metaplasia. We investigated whether uncontrolled reflux is associated with persistent intestinal metaplasia after RFA. METHODS Thirty-seven patients with BE underwent RFA, high-resolution manometry, and 24-hour impedance-pH testing; they received proton pump inhibitors twice daily. Patients returned every 2 months for repeat treatment or standard surveillance. Patients were classified as complete responders (CRs) if all intestinal metaplasia was eradicated in fewer than 3 ablation sessions. We analyzed clinical parameters to identify factors associated with a CR or incomplete responder (ICR). RESULTS Among the 37 patients, 22 had a CR and 15 had an ICR. Mann-Whitney U tests revealed that length of BE, size of hiatal hernia, and frequency of reflux, but not acid reflux, differed between CRs and ICRs. CRs had fewer weakly acidic events than ICRs (29.5 vs 52; P < .05) and total reflux events (33.5 vs 60; P < .05), and a trend toward fewer weakly alkaline events (1.0 vs 5.0; P = .06). No other clinical or manometric features differed between groups. CONCLUSIONS Uncontrolled, predominantly weakly acidic reflux despite twice-daily proton pump inhibitor therapy before RFA increases the incidence of persistent intestinal metaplasia after ablation in patients with BE. Length of BE and size of hiatal hernia also were associated with persistent intestinal metaplasia after RFA.

BACKGROUND AND AIM The aim of this study was to assess whether the efficacy of proton pump inhibitors (PPI) therapy at a standard dose in esophageal acid control is affected by the presence of hiatus hernia in Chinese gastroesophageal reflux disease patients, and whether a higher dose of PPI is required for acid control. METHODS Consecutive gastroesophageal reflux disease patients who had typical reflux symptoms and abnormal baseline 24-h esophageal pH and underwent upper endoscopy were enrolled to receive esomeprazole at 40 mg once daily for 4 weeks. Patients underwent the dual-channel 24-h pH test at the end of 4-week therapy. If the 24-h esophageal pH was still abnormal at the end of 4-week therapy, then esomeprazole at 40 mg twice daily was given for another 4 weeks after a washout interval of 1 week, and a 24-h pH test was repeated at the end of the therapy. RESULTS Overall, 76 patients were included, 13 with hiatus hernia. Of the 76 patients treated with a 40 mg of esomeprazole daily, esophageal acid exposure was normalized in 64 (84.2%). Normalization of acid exposure was achieved by standard PPI therapy in 53.2% (7/13) of patients with hiatus hernia and 90.5% (57/63) of those without (P = 0.004). A double dose of esomeprazole was successful in normalizing the esophageal pH in all 12 non-responders to the standard dose of esomeprazole, including the six patients with hiatus hernia and six patients without. CONCLUSIONS The standard-dose of esomeprazole fails to normalize the esophageal pH in almost 50% of patients with hiatus hernia, in whom the "double-dose" esomeprazole therapy is required.

Abstract
Hiatal hernia is an underlying factor contributing to gastroesophageal reflux disease (GERD). However, it remains elusive whether the size of the esophageal hiatus has a de facto influence on the lower esophageal sphincter (LES), on the intensity of patient reflux, on GERD symptoms and on the quality of life (QoL). One hundred patients with documented chronic GERD underwent laparoscopic fundoplication. QoL was evaluated before surgery using the Gastrointestinal Quality of Life Index (GIQLI). Additionally, GERD symptoms and nonspecific gastrointestinal symptoms were documented using a standardized questionnaire (score 0-224). The size of the esophageal hiatus was measured during surgery by calculating the hiatal surface area (HSA). Correlation analysis between the preoperative QoL, GERD symptoms, esophageal manometry, multichannel intraluminal impedance monitoring data and HSA size was performed, in order to investigate whether the HSA has an influence on the patients'symptoms, GIQLI, manometry and multichannel intraluminal impedance monitoring data. Statistical significance was set at a P-value of 0.05. The HSA sizes ranged from 1.51cm(2) to 16.09cm(2) (mean 4.14cm(2) ). The preoperative GIQLI ranged from 15 points to 133 points (mean 94.37 points). Symptom scores ranged from 2 points to 192 points (mean 49.84 points). No significant influence of the HSA on GIQLI or preoperative symptoms was recorded. HSA size had a significant negative effect on LES pressure. Additionally, there was a significant positive correlation between HSA size and number of refluxes in supine position. For the rest of the evaluated data, including DeMeester score, total number of refluxes, refluxes in upright position, acid reflux events, proximal reflux events, LES length and body motility, no significant correlation was found. Although patients subjectively are not significantly affected by the size of the hiatus, it has significant effects on the LES pressure and on gastroesopageal reflux in supine position.

Abstract
High-resolution manometry (HRM) has now become widely available and currently is moving into mainstream clinical practice. This article provides an HRM-related atlas of esophageal motility disorders focused on dysphagia and gastroesophageal reflux disease (GERD). Although there is some overlap between esophageal motor disorders associated with dysphagia and the defects and esophageal motor function that would predispose the patient to more severe GERD, this review is organized to differentiate the distinct pathophysiologic components of the two disease groups. A section on impaired bolus transit is also included to highlight the important aspect of impaired clearance in the pathogenesis of GERD.
