Airway pepsinogen A4 identifies lung transplant recipients with microaspiration and predicts chronic lung allograft dysfunction. J Heart Lung Transplant 2024; 43:973-982. [PMID: 38211836 DOI: 10.1016/j.healun.2024.01.002] [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: 08/13/2023] [Revised: 12/04/2023] [Accepted: 01/02/2024] [Indexed: 01/13/2024] Open
Abstract
BACKGROUND Aspiration is a known risk factor for adverse outcomes post-lung transplantation. Airway bile acids are the gold-standard biomarker of aspiration; however, they are released into the duodenum and likely reflect concurrent gastrointestinal dysmotility. Previous studies investigating total airway pepsin have found conflicting results on its relationship with adverse outcomes post-lung transplantation. These studies measured total pepsin and pepsinogen in the airways. Certain pepsinogens are constitutively expressed in the lungs, while others, such as pepsinogen A4 (PGA4), are not. We sought to evaluate the utility of measuring airway PGA4 as a biomarker of aspiration and predictor of adverse outcomes in lung transplant recipients (LTRs) early post-transplant. METHODS Expression of PGA4 was compared to other pepsinogens in lung tissue. Total pepsin and PGA4 were measured in large airway bronchial washings and compared to preexisting markers of aspiration. Two independent cohorts of LTRs were used to assess the relationship between airway PGA4 and chronic lung allograft dysfunction (CLAD). Changes to airway PGA4 after antireflux surgery were assessed in a third cohort of LTRs. RESULTS PGA4 was expressed in healthy human stomach but not lung. Airway PGA4, but not total pepsin, was associated with aspiration. Airway PGA4 was associated with an increased risk of CLAD in two independent cohorts of LTRs. Antireflux surgery was associated with reduced airway PGA4. CONCLUSIONS Airway PGA4 is a marker of aspiration that predicts CLAD in LTRs. Measuring PGA4 at surveillance bronchoscopies can help triage high-risk LTRs for anti-reflux surgery.

Laparoscopic Large Hiatal Hernia Repair With RefluxStop: Outcomes of Six Months Follow-up in Thirty Patients. Surg Laparosc Endosc Percutan Tech 2024; 34:143-149. [PMID: 38421213 PMCID: PMC10986782 DOI: 10.1097/sle.0000000000001256] [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: 03/15/2023] [Accepted: 10/04/2023] [Indexed: 03/02/2024]
Abstract
OBJECTIVE The antireflux surgical technique with the RefluxStop device is one of the latest approaches to treating patients with gastroesophageal reflux disease (GERD). The aim of this study was to assess the safety and feasibility of laparoscopic hiatal hernia (HH) repair with the RefluxStop device in patients with GERD and concurrent large HH (≥4 cm). PATIENTS AND METHODS A retrospective chart review was performed for the first 30 patients with a large HH who consented and underwent HH surgery with the RefluxStop device. The operative technique and outcomes were evaluated to assess safety and feasibility, HH recurrence, dysphagia, and patient satisfaction. RESULTS Between May 2020 and April 2022, 30 patients underwent laparoscopic HH repair with the RefluxStop device. All patients had typical symptoms of GERD, such as heartburn and regurgitation, and 15 patients (50%) had preoperative dysphagia. Median HH size was 5 cm (interquartile range, 4 to 5). Median operating time was 56 minutes (interquartile range, 52 to 63), with no intra and postoperative complications related to the device. One patient required laparotomy due to adhesions and associated bleeding when accessing the abdomen. All patients had postoperative imaging (video fluoroscopy) on postoperative day 1 and at 3 months, confirming the correct location of the RefluxStop device. One patient (3.3%) needed postoperative balloon dilatation due to severe dysphagia. Reflux symptoms (heartburn and acid regurgitation) resolved significantly in all patients ( P < 0.001) at 6 months. One episode of recurrence of HH (3.3%) occurred during the follow-up period of 6 months. CONCLUSION This study demonstrates the short-term safety and feasibility of laparoscopic HH repair with the RefluxStop device in patients with large HH, with a low rate of postoperative dysphagia and subsequent improvement or resolution of reflux symptoms in all patients.

Abstract
BACKGROUND Different surgical techniques exist in the treatment of giant and complex hiatal hernia. The aim of this study was to identify the role of the Belsey Mark IV (BMIV) antireflux procedure in the era of minimally invasive techniques. METHODS A single-center, retrospective cohort study was conducted. All patients who underwent an elective BMIV procedure aged 18 years or older, during a 15-year period (January 1, 2002 until December 31, 2016), were included. Demographics, pre-, per- and postoperative data were analyzed. Three groups were compared. Group A: BMIV as first procedure-group B: BMIV as a second procedure (first redo intervention)-group C: patients who had two or more previous antireflux interventions. RESULTS A total of 216 patients were included for analysis (group A n = 127; group B n = 51; group C n = 38). Median follow-up in groups A, B and C was 28, 48 and 56 months, respectively. Patients in group A were older and had a higher American Society of Anesthesiologists score compared to groups B and C. There was zero mortality in all groups. The severe complication rate of 7.9% in group A was higher compared with the 2.9% in group B and 3.9% in group C. Long-term outcome showed true recurrence, defined as both radiographic recurrence as well as associated symptoms, in 9.5% of cases in group A, 24.5% in group B and 44.7% in group C. CONCLUSIONS The BMIV procedure is a safe procedure with good results, moreover in the aging and comorbid patient with primary repair of a giant hiatal hernia.

Abstract
Background: The current gold standard of treatment for giant hiatal hernias (GHHs) is laparoscopic surgery. Laparoscopic surgery was performed as a less invasive procedure for paraesophageal hernias more than 25 years ago. Its viability and safety have almost all been shown. Materials and Methods: A review of recent and current studies' literature was done. Prospective randomized trials, systematic reviews, clinical reviews, and original articles were all investigated. The data were gathered in the form of a narrative evaluation. We examine the state of laparoscopic GHH repair today and outline the GHH management strategy. Results: In this review, we clear up misunderstandings of GHH and address bad habits that may have contributed to poor results, and we have consequently performed a methodical evaluation of GHH. First, we address subcategorizing GHH and provide criteria to define them. The preoperative workup strategies are then discussed, with a focus on any pertinent and frequent atypical symptoms, indications for surgery, timing of surgery, and the importance of surgery. The approach to the techniques and the logic behind surgery are then presented along with some important dissection techniques. Finally, we debate the role of mesh reinforcement and evaluate the data in terms of recurrence, reoperation rate, complications, and delayed stomach emptying. Finally, we suggest a justification for common postoperative investigations. Conclusions: Surgery is the only effective treatment for GHH at the moment. If the right operational therapy principles are applied, this is generally successful. There is a growing interest in laparoscopic paraesophageal hiatal hernia repair as a result of the introduction of laparoscopic antireflux surgery. Today's less invasive procedures provide a better therapeutic choice with a lower risk.

Is systematic formal crural repair mandatory at the time of magnetic sphincter augmentation implantation? Dis Esophagus 2023:6972914. [PMID: 36617229 DOI: 10.1093/dote/doac108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 10/21/2022] [Accepted: 12/06/2022] [Indexed: 01/09/2023]
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
Coronary atherosclerosis (CAS) and gastroesophageal reflux disease (GERD) share common risk factors. The existing CAS may not only increase the possibility of GERD to be refractory GERD (RGERD), but also increase the risk of antireflux surgery for these patients. The aim of this study was to estimate the prevalence of CAS and its potential risk factors in patients with RGERD ready for antireflux surgery. The retrospective analysis was performed in the digestive disease center of Suining Central Hospital, a teritary hospital in Sichuan, China. Records of patients with RGERD admitted to the hospital for antireflux surgery between July 2018, and June 2021 were included. The included patients were divided into the RGERD group and RGERD-CAS group based on the coronary computed tomography angiography (CCTA) results, which were defined as no CAS and CAS (<50% mild stenosis or ≥50% significant stenosis). In total, 448 patients with RGERD qualified for the study. The prevalence of CAS in these patients was 45.1%. Specifically, 246 patients (54.9%) were in the RGERD group, and 202 patients (45.1%) were in the RGERD-CAS group. Among these 202 patients with CAS, 120 patients (59.4%) had mild CAS (<50% stenosis), 82 patients (40.6%) had significant CAS (≥50% stenosis). Five independent risk factors, including male sex, high blood pressure (HBP), diabetes mellitus (DM), Barrett's esophagus (BE) and family history of coronary artery disease were identified for the occurrence of CAS in patients with RGERD ready for antireflux surgery after adjusting for other factors. CAS is prevalent in patients with RGERD ready for antireflux surgery. Routing CTTA was suggested to exclude potential coronary artery disease in RGERD patients ready for antireflux surgery with independent risk factors.

Fluorescence-Guided Surgery (FGS) during a Laparoscopic Redo Nissen Fundoplication: The First Case in Children. CHILDREN (BASEL, SWITZERLAND) 2022; 9:947.

Abstract
We present the first case of fluorescence-guided surgery (FGS) using indocyanine green (ICG) in a pediatric redo-Nissen fundoplication. The patient is a 17-year-old male with recurrent gastroesophageal symptoms who underwent primary antireflux surgery at 10 months of age. During the redo fundoplication, ICG was intravenously administered to help the visualization during the adhesiolysis between liver, stomach and right crus of the diaphragm and to spare small oesophageal vessels and the left gastric artery. In this case, FGS made the surgery easier than usual and likely reduced the risk of intra-operative complications. Therefore, we believe that this new technology should be regularly used in these types of complex intra-abdominal redo operations.

How effective is laparoscopic redo- antireflux surgery? Dis Esophagus 2022; 35:6490086.

Abstract
BACKGROUND The failure-rate after primary antireflux surgery ranges from 3 to 30%. Reasons for failures are multifactorial. The aim of this study is to gain insight into the complex reasons for, and management of, failure after antireflux surgery. METHODS Patients were selected for redo-surgery after a diagnostic workup consisting of history and physical examination, upper gastrointestinal endoscopy, quality-of-life assessment, screening for somatoform disorders, esophageal manometry, 24-hour-pH-impedance monitoring, and selective radiographic studies such as Barium-sandwich for esophageal passage and delayed gastric emptying. Perioperative and follow-up data were compiled between 2004 and 2017. RESULTS In total, 578 datasets were analyzed. The patient cohort undergoing a first redo-procedure (n = 401) consisted of 36 patients after in-house primary LF and 365 external referrals (mean age: 62.1 years [25-87]; mean BMI 26 [20-34]). The majority of patients underwent a repeated total or partial laparoscopic fundoplication. Major reasons for failure were migration and insufficient mobilization during the primary operation. With each increasing number of required redo-operations, the complexity of the redo-procedure itself increased, follow-up quality-of-life decreased (GIQLI: 106; 101; and 100), and complication rate increased (intraoperative: 6,4-10%; postoperative: 4,5-19%/first to third redo). After three redo-operations, resections were frequently necessary (morbidity: 42%). CONCLUSIONS Providing a careful patient selection, primary redo-antireflux procedures have proven to be highly successful. It is often the final chance for a satisfying result may be achieved upon performing a second redo-procedure. A third revision may solve critical problems, such as severe pain and/or inadequate nutritional intake. When resection is required, quality of life cannot be entirely normalized.

Abstract
Background Assessing the value of a treatment is of great importance. Typical methods are directed toward policy decisions. However, individual stakeholders will have different valuation based on their interests. Methods Formulas were developed to quantify the value of a treatment from the patient, surgeon, hospital, and private third-party payer. These formulas are based on observed factors that go into treatment decision-making for each stakeholder. Using the example of four surgical treatment options for gastroesophageal reflux disease, values for each factor were obtained from publically available documents or were arbitrarily estimated. Results From the patient perspective, the laparoscopic Nissen fundoplication (LNF) provided the best value at 2.99 quality-adjusted life years per $1,000 spent. From the surgeon perspective, it provided the best value at $752.20 earned per hour effort. From the hospital perspective, LNP provided the best value at $3,446 earned per episode of care. Lastly, from the third-party payer perspective, total incisionless fundoplication provided the best value at $13,336 per year. Conclusions Because value is measured differently for each stakeholder, there will be conflicts as to how treatment options are valued.

Abstract
In up to half of patients with symptoms suspected to stem from gastroesophageal reflux disease (GERD), these symptoms persist despite treatment with daily proton pump inhibitor (PPI) therapy. The symptoms may be characterized as typical (eg, heartburn or regurgitation) or atypical (eg, chest pain or cough). These refractory symptoms, which are frequently encountered in clinical practice, may stem from GERD as well as non-GERD etiologies. Among those patients with objective GERD proven on esophagogastroduodenoscopy (EGD) and/ or ambulatory reflux testing, approximately one-fifth may manifest suboptimal symptom response to PPI therapy. After introducing the initial evaluation of patients with suspected GERD symptoms, this article discusses approaches to the esophageal diagnostic workup of patients with refractory symptoms in the setting of proven GERD, focusing on EGD, high-resolution manometry (HRM), and pH-impedance monitoring during treatment with PPI therapy. EGD evaluates for esophagitis, peptic stricture, and hiatal hernia, as well as eosinophilic esophagitis. HRM rules out confounding esophageal motor disorders, identifies behavioral disorders, characterizes the antireflux barrier, and assesses esophageal contractile reserve to help tailor potential antireflux interventions. pH-impedance monitoring during treatment with PPI therapy can help distinguish between PPI-refractory GERD-as evidenced by pathologic acid exposure despite PPI therapy and/or excess burden of reflux events regardless of acidity-and PPI-controlled GERD. This article also discusses potential approaches for patients with symptoms stemming from refractory GERD, encompassing lifestyle, pharmacologic, endoscopic, and surgical management options.

Abstract
GOALS To assess the long-term results of transoral incisionless fundoplication (TIF 2). BACKGROUND TIF with the EsophyX2 is an accepted procedure to treat gastroesophageal reflux disease (GERD). Long-term data have been limited. We report clinical outcomes of 151 patients followed up to 9 years. STUDY A single institution prospective registry of patients undergoing TIF 2 between 11/2008 and 7/2015. Outcomes were assessed by complications, re-interventions, and a mixed effect model of clinical response over time. RESULTS A total of 151 patients (87 women), mean age 62 years (30-91), mean body mass index (BMI) 26.6 (20-36.1), 93% on daily proton pump inhibitor (PPI), underwent TIF 2 without hiatal hernia repair; 131 of the 151 patients (86%) were available for follow-up at a median of 4.92 years (0.7-9.7 years). Of 120 patients ⩾5 years post-TIF, 62 (51%) were followed for a median 6.8 years. Median GERD-health-related quality of life (HRQL) scores decreased from 21 (interquartile range (IQR) 9.5-30) off PPI and 14 (4-24) on PPI at baseline to 4 (2-8) at 4.92 years and remained at 5 (2-9) in the 62 patients 5-9 years post-TIF. Sixty-four per cent had successful (>50%) reductions in GERD-HRQL scores at 4.92 years and 68% of patients followed ⩾5 years. Median regurgitation decreased from 15 (8-20) off PPI and 11 (5-20) on PPI at baseline to 0 (0-4) at 4.92 years, remaining at 1 (0-3) in 62 patients 5-9 years post-TIF. Mixed model analyses confirmed significant and stable improvements in GERD-HRQL and regurgitation scores at all annual follow-up time points after TIF. Daily PPI use decreased from 93% to 32% at 4.92, and 22% at ⩾5 years post-TIF. Revision to laparoscopic fundoplication in 33(22%) showed comparable outcomes. Two patients recovered uneventfully after laparoscopic surgery for localized perforation. CONCLUSIONS TIF 2 provides durable relief of GERD symptoms at up to 9 years with 69-80% of patients having a successful outcome by symptom response and PPI use.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is associated with accelerated decline in lung health in children with cystic fibrosis (CF). Thus, antireflux surgery (ARS) is offered to a selected CF cohort with refractory GERD, but outcomes remain poorly investigated. This study aimed to determine the incidence of GERD in children with CF and to evaluate complications and outcomes of ARS. MATERIALS AND METHODS A systematic literature-based search was conducted using various online databases according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The number of GERD cases in pediatric CF cohorts who underwent diagnostic investigation(s) was recorded. Data on postoperative complications and outcomes (including symptoms, lung function, and nutritional status) following ARS were analyzed. RESULTS Ten articles (n = 289 patients) met the defined inclusion criteria (51% male; age range, 0.5 month-36 years). The overall incidence of GERD was 46% (range, 19-81%), derived from seven studies (n = 212 patients). Four publications (n = 82 patients) reported on ARS due to uncontrolled GERD. All ARSs were Nissen fundoplication (majority with gastrostomy placement). Major postoperative complications occurred in 15 (18%) patients, two required redo-ARS. Median follow-up time was 2 years (range, 3 months-6 years); 59% showed symptom improvement, and pulmonary exacerbations and decline in lung function were reduced. Nutritional status mainly improved in milder CF cases. There were no deaths related to ARS. CONCLUSION Approximately half of pediatric CF patients have GERD. Published data for children with CF are limited and heterogeneous in terms of GERD diagnosis and outcomes following ARS. However, ARS has shown to slow the deterioration of lung function in CF.

Abstract
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.

Abstract
Background. Anti-reflux surgery is an effective treatment for gastroesophageal reflux disease (GERD). Nevertheless, surgery is still indicated with great caution in relation to the risk of complications, and in particular to postoperative dysphagia (PD). Objective. To compare the clinical outcomes, with particular focus on the incidence and severity of PD, of laparoscopic Nissen-Rossetti fundoplication (NRF) and floppy Nissen fundoplication (FNF) with complete fundus mobilization, in the surgical treatment of GERD. Methods. Ninety patients with GERD were enrolled. Forty-four patients (21[47.7%] men, 23[52.2%] women; mean age 42.4 ± 14.3 years) underwent NRF (Group A), and 46 patients (23[50%] men, 23[50%] women; mean age 43.3 ± 15.4 years) received laparoscopic FNF with complete fundus mobilization (Group B). Clinical assessment was performed using a structured questionnaire and SF-36 quality of life (QoL) score. PD was assessed using a validated classification, and an overall outcome was also determined by asking the patient to score it. Results. At 24-month follow-up, 38 (88.3%) patients in Group A vs 39 (86.6%) in Group B reported to be completely satisfied with reflux relief and free of protonic pump inhibitors (PPIs), while 3 (6.9%) in Group A vs 2(4.4%) in Group B reported occasional PPI intake and 2(4.6%) in Group A vs 4(8.8%) in Group B needed regular PPI use. Persistent PD was observed in 8(18.6%) patients in Group A and in 2(4.4%) in Group B (P = .03). No significant differences were found in the QoL score and in the overall outcome perceived by the patients. Conclusion. FNF, with complete fundus mobilization, appears to be associated with a lower rate of postoperative persistent dysphagia.

Abstract
Background. Objective measures including the DeMeester score, lower esophageal sphincter (LES) pressure, acid exposure time, and body mass index (BMI) are used to determine gastroesophageal reflux disease (GERD) severity and eligibility for various antireflux surgical procedures. The GERD Health-Related Quality of Life (GERD-HRQL) survey is widely used to evaluate patients' subjective severity of symptoms and GERD-related quality of life. The purpose of this project was to identify whether or not the subjective measure (GERD-HRQL) correlated with objective measures (DeMeester score, LES, acid exposure time, and BMI) of GERD severity. Methods. A retrospective review of the medical records of patients who underwent antireflux surgery from 2013-2018 was completed. Patients' GERD severity was measured preoperatively and postoperatively using the GERD-HRQL. Statistical analysis included the calculation of Spearman correlation coefficients, Wilcoxon rank sum, sign, and chi-square tests. Results. 151 patients were included in the study; 64% were female. The mean age and BMI were 54.6 ± 14.6 years and 30.1 ± 4.1 kg/m2, respectively. The mean preoperative DeMeester score was 43.1 ± 36.1, LES pressure was 19.9 ± 18.4 mmHg, and acid exposure time was 11.4 ± 9.6. Mean GERD-HRQL scores decreased from 27.3 ± 9.2 preoperative to 5.3 ± 4.5 postoperative; P < .0001. Preoperative GERD-HRQL scores were not correlated with the DeMeester score (r = .11; P = .389), LES pressure (r = -.20; P = .089), acid exposure time (r = .05; P = .755), BMI (r = .10; P = .329), or age (r = -.16; P = .118). Conclusions. Total GERD-HRQL scores significantly decreased from pre- to postoperative. There was no correlation between subjective and objective GERD scoring. These data indicate the need for both physiologic evaluation and subjective assessment of patient symptoms during preoperative workup. There is a need for a contemporary, validated GERD questionnaire that correlates with objective pH testing.

Abstract
Introduction: Many studies on short-term efficacy of laparoscopic antireflux surgery (LARS) have shown good to excellent results on reflux symptom control and health-related quality of life (HRQoL). Prospective studies on the long-term efficacy, however, are scarce and indicate that the efficacy of symptom control may decline over time. The aim of this study is to assess the 2-year outcome on reflux symptoms and HRQoL after LARS. Materials and Methods: Between 2011 and 2013, 25 children (12 males, median age 6 [2-18] years) with proton pump inhibitor-resistant gastroesophageal reflux disease were included in a prospective longitudinal cohort study. To assess reflux symptoms and HRQoL, patients and/or their caregivers were asked to fill out the validated age-appropriate gastroesophageal reflux symptom questionnaire and Pediatric Quality of Life Inventory™ before, 3 months, 1 year, and 2 years after LARS. Results: Two years after LARS, 29% of patients had moderate to severe reflux symptoms compared with 92% (P < .001) before operation and 12% 3-4 months after operation (P = .219). The significant increase in HRQoL shortly after fundoplication (80.0 compared with 69.5 (P = .004)) is not observed after 2 years (72.0 compared with 69.5, P = .312). Correlation between the impaired HRQoL scores and the recurrence of symptoms could not be verified. Conclusions: Although the efficacy of LARS tends to deteriorate after 2 years, LARS is still effective in controlling reflux symptoms in the majority of patients. The short-term improvement in HRQoL after LARS appears to be transient.

Pyloric distensibility measurement after gastric surgery: Which surgeries are associated with pylorospasm? Neurogastroenterol Motil 2020; 32:e13790. [PMID: 31916346 DOI: 10.1111/nmo.13790] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Accepted: 12/13/2019] [Indexed: 01/19/2023]
Abstract
BACKGROUND AND STUDY AIMS History of gastric surgery is found in 10% of patients with gastroparesis, and vagal lesion is often suspected to be the cause of pylorospasm. Recently, pyloric distensibility measurement using the EndoFLIP® system showed that pylorospasm was present in 30%-50% of gastroparetic patients. Our objective was to assess whether pylorospasm, diagnosed using EndoFLIP® system was observed in three different types of gastric surgeries: antireflux surgery, sleeve gastrectomy, and esophagectomy. PATIENTS AND METHODS Pyloric distensibility and pressure were measured using the EndoFLIP® system in 43 patients from two centers (18 antireflux surgery, 16 sleeve gastrectomy, and nine esophagectomy) with dyspeptic symptoms after gastric surgery, and in 21 healthy volunteers. Altered pyloric distensibility was defined as distensibility below 10 mm2 /mm Hg as previously reported. RESULTS Compared to healthy volunteers (distensibility: 25.2 ± 2.4 mm2 /mm Hg; pressure: 9.7 ± 4.4 mm Hg), pyloric distensibility was decreased in 61.1% of patients in the antireflux surgery group (14.5 ± 3.4 mm2 /mm Hg; P < .01) and 75.0% of patients in the esophagectomy group (10.8 ± 2.1 mm2 /mm Hg; P < .05), while pyloric pressure was only increased in the antireflux surgery group (18.9 ± 2.2 mm Hg; P < .01). Pyloric distensibility and pressure were similar in healthy volunteers and in sleeve gastrectomy (distensibility: 20.3 ± 3.8 mm2 /mm Hg; pressure: 15.8 ± 1.6 mm Hg) groups, with decreased pyloric distensibility affecting 18.7% of sleeve gastrectomy patients. CONCLUSION Antireflux surgery and esophagectomy were associated with pylorospasm although pylorospasm was not found in all patients. Sleeve gastrectomy was not associated with altered pyloric distensibility nor altered pyloric pressure.

Abstract
Gastroesophageal reflux disease (GERD) is a common disorder that is treated with lifestyle modification, weight loss, and medications, such as proton pump inhibitors (PPIs). An empiric course of PPI therapy is an effective and cost-effective strategy for the management of GERD. However, in some patients, PPI therapy and lifestyle changes are inadequate to control symptoms. When there is persistence of symptoms despite empiric therapy, patients are labeled as having refractory GERD. This label underestimates the wide differential diagnosis of foregut pathology that can mimic symptoms of GERD. A careful history of symptoms, response to PPI therapy, adherence, compliance, and timing helps elucidate if medication has been helping. When patients are refractory, alternative etiologies of GERD must be considered. Many of these alternatives can be determined on an upper endoscopy or with complementary testing, such as high-resolution esophageal manometry or gastric emptying testing as symptoms dictate. When an alternative cause is not found and index endoscopy is normal, additional testing with either traditional pH or impedance testing can be completed based on prior examination results and response to therapy. Further therapy, including medical, endoscopic, or surgical, can then be targeted at the etiology.

Abstract
OBJECTIVE To identify predictors of and factors associated with the performance of antireflux surgery during the first year of life in children born with esophageal atresia. STUDY DESIGN All patients were included in a French registry for esophageal atresia. All 38 multidisciplinary French centers completed questionnaires about perinatal characteristics and one-year outcome for children born with esophageal atresia. RESULTS Of 835 infants with esophageal atresia born in France from 2010 to 2014, 682 patients, excluding those with long-gap esophageal atresia, were included. Three patients had type I, 669 had type III, and 10 had type IV esophageal atresia. Fifty-three children (7.8%) received fundoplication during the first year of life. The median age at the time of the end-to-end esophageal anastomosis was 1.1 day (range 0-15). Multivariate analysis identified three perioperative factors that predicted the need for early antireflux surgery: anastomotic tension (P = .004), associated malformations (P = .019), and low birth weight (P = .018). Six other factors, measured during the first year of life, were associated with the need for antireflux surgery: gastroesophageal reflux (P < .001), anastomotic stricture (P < .001), gastrostomy (P < .001), acute life-threatening event (P = .002), respiratory complications (P = .045), and poor nutritional status (P < .001). CONCLUSIONS Gastroesophageal reflux disease, low birth weight, poor nutrition, and surgical anastomosis difficulties predicted the performance of antireflux surgery in the first year of life in infants with esophageal atresia.

Gastroesophageal reflux in children: an updated review. Drugs Context 2019; 8:212591.

Abstract
Background Gastroesophageal reflux is a common disorder in pediatrics. Clinicians should be familiar with the proper evaluation and management of this condition. Objective To provide an update on the current understanding, evaluation, and management of gastroesophageal reflux in children. Methods A PubMed search was performed with Clinical Queries using the key term ‘gastroesophageal reflux’. The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to the English literature and the pediatric age group. Results Regurgitation is the most frequent symptom of gastroesophageal reflux and is present in nearly all cases. Gastroesophageal reflux occurs normally in infants, is often physiological, peaks at 4 months of age, and tends to resolve with time. Gastroesophageal reflux disease occurs when gastric contents reflux into the esophagus or oropharynx and produce troublesome symptom(s) and/or complication(s). A thorough clinical history and a thorough physical examination are usually adequate for diagnosis. When the diagnosis is ambiguous, diagnostic studies may be warranted. A combined esophageal pH monitoring and multichannel intraluminal esophageal electrical impedance device is the gold standard for the diagnosis of gastroesophageal reflux disease if the diagnosis is in doubt. In the majority of cases, no treatment is necessary for gastroesophageal reflux apart from reassurance of the benign nature of the condition. Treatment options for gastroesophageal reflux disease are discussed. Conclusion In most cases, no treatment is necessary for gastroesophageal reflux apart from reassurance because the condition is benign and self-limiting. Thickened feedings, postural therapy, and lifestyle changes should be considered if the regurgitation is frequent and problematic. Pharmacotherapy should be considered in the treatment of more severe gastroesophageal reflux disease for patients who do not respond to conservative measures. Proton pump inhibitors are favored over H2-receptor antagonists because of their superior efficacy. Antireflux surgery is indicated for patients with significant gastroesophageal reflux disease who are resistant to medical therapy.

Abstract
AIM As a result of the difficulty in effective prevention of gastroesophageal reflux, no standard reconstruction procedure after proximal gastrectomy (PG) has yet been established. The double-flap technique (DFT), or Kamikawa procedure, is an antireflux reconstruction procedure in esophagogastrostomy. The efficacy of DFT has recently been reported in several studies. However, these were all single-center studies with a limited number of cases. METHODS We conducted a multicenter retrospective study in which patients who underwent DFT, irrespective of disease type and reconstruction approach, at each participating institution between 1996 and 2015 were registered. Primary endpoint was incidence of reflux esophagitis at 1-year after surgery, and secondary endpoint was incidence of anastomosis-related complications. RESULTS Of 546 patients who were eligible for this study, 464 patients who had endoscopic examination at 1-year follow up were evaluated for reflux esophagitis. Incidence of reflux esophagitis of all grades was 10.6% and that of grade B or higher was 6.0%. Male gender and anastomosis located in the mediastinum/intra-thorax were independent risk factors for grade B or higher reflux esophagitis (odds ratio [OR]: 4.21, 95% confidence interval [CI]: 1.44-10.9, P = 0.0109). Total incidence of anastomosis-related complications was 7.2%, including leakage in 1.5%, strictures in 5.5% and bleeding in 0.6% of cases. Laparoscopic reconstruction was the only independent risk factor for anastomosis-related complications (OR: 3.93, 95% CI: 1.93-7.80, P = 0.0003). CONCLUSION Double-flap technique might be a feasible option after PG for effective prevention of reflux, although anastomotic stricture is a complication that must be well-prepared for.

Abstract
BACKGROUND Controversy exists regarding the best surgical approach for the management of gastroesophageal reflux disease (GORD) and associated preoperative esophageal dysmotility. Our aim was to conduct a systematic review and meta-analysis to compare the outcomes of Toupet fundoplication (TF) and Nissen fundoplication (NF) in patients with GORD and coexistent preoperative esophageal dysmotility. METHODS We conducted a systematic search of electronic information sources, including MEDLINE, EMBASE, CINAHL, CENTRAL, ClinicalTrials.gov , and bibliographic reference lists. We applied a combination of free text search and controlled vocabulary search adapted to thesaurus headings, search operators, and limits in each of the above-mentioned databases. Postoperative dysphagia and improvement in dysphagia were primary outcome parameters. RESULTS We identified 3 randomized controlled trials and 1 observational study reporting a total of 220 patients, of whom 126 underwent TF and the remaining 94 patients had NF. Despite the existence of significantly higher preoperative dysphagia in the TF group (29.3% vs 4.2%, P = .05), TF was associated with significantly lower postoperative dysphagia (odds ratio [OR] = 0.31, P = .002) with low between-study heterogeneity ( I2 = 11%, P = .34), and significantly higher improved dysphagia (OR = 10.32, P < .0001) with moderate between-study heterogeneity ( I2 = 31%, P = .23) compared with NF. CONCLUSION TF may be associated with significantly lower postoperative dysphagia than NF in patients with GORD and associated preoperative esophageal dysmotility. However, no definite conclusions can be drawn as the best available evidence comes mainly from a limited number of heterogeneous randomized controlled trials. Future studies are encouraged to include patients with similar preoperative dysphagia status and report the outcomes with respect to recurrence of acid reflux symptoms.

Abstract
Since 2011, endoscopic correction of vesicoureteral reflux using dextranomer-hyaluronic acid copolymer (Deflux®) has been widely accepted in Japan due to its safety and minimally invasive nature. However, long-term complications are unknown. We present a case of Deflux® implants calcification mimicking distal ureteral calculi in a 12-year-old boy with a history of Deflux® injection performed at three years of age for primary VUR. We should be aware of this complication to avoid misdiagnosis and unnecessary invasive examination such as radiological imaging or endoscopy.

Peroral endoscopic myotomy versus surgical myotomy for primary achalasia: single-center, retrospective analysis of 74 patients. Dis Esophagus 2017; 30:1-7.

Abstract
Achalasia is a neurodegenerative motility disorder of the esophagus; dysphagia, weight loss, chest pain, and regurgitation are its main symptoms. Surgical myotomy (HM) is considered the gold standard treatment. However, peroral endoscopic myotomy (POEM) seems to be a safe and effective alternative option. The aim of this study is to compare the safety and efficacy of these techniques. From March 2012 to June 2015, 74 patients with symptomatic primary achalasia underwent myotomy. The two groups were compared in terms of intraoperative and postoperative outcomes and Eckardt score at last follow-up. A morphofunctional comparison was also performed. Thirty-two myotomies were performed endoscopically (POEM group) and 42 were performed laparoscopically with a 180° anterior fundoplication (surgical myotomy [SM] group). Operative time was significantly shorter for the POEM group (63 [range: 32-114] vs. 76 minutes [54-152]; P = 0.0005). Myotomy was significantly longer for the POEM group (12 [range: 10-15] vs. 9 cm [range: 7-10]; P = 0.0001). Postoperative morbidity occurred in two patients (4.7%) in the SM group; no complications (P = not significant) were recorded for the POEM group. The median Eckardt score at last follow-up decreased for each group from 6 to 1 (P < 0.001). Morphological evaluation was performed for 20 patients and functional evaluation was performed in 18 patients of each group. Lower esophageal sphincter resting and relaxation pressures were significantly reduced in both groups (P < 0.001). Eight patients in the POEM group (40%) had esophagitis at endoscopy: 4 (20%) with Los Angeles (LA) grade A, 3 (15%) with LA grade B, and 1 patient with LA grade D (5%). Five patients in POEM group (28%) had a pathologic DeMeester score. In the SM group, one patient (5%) had esophagitis (P = 0.04; 95% CI) and 4 patients (22%) presented a pathological DeMeester score. Perioperative results for POEM and SM are similar. The absence of an antireflux wrap leads to an increased risk of reflux with consequent esophagitis. SM with an antireflux wrap could be a preferred choice when a long standing gastroesophageal reflux could potentially lead to a damage as, for example, in young patients.

Abstract
BACKGROUND Laparoscopic Nissen fundoplication is a commonly performed antireflux surgery, after which reflux symptoms are well controlled, however, complications such as inability to belch or dyspeptic symptoms (mimicking those of functional dyspepsia [FD]) might occur. The aim of the study was to prospectively evaluate symptom pattern and underlying pathophysiological mechanisms in patients with post-Nissen dyspepsia. METHODS Twenty-four patients (12 f, mean age 44.5±2.8 years) with post-Nissen dyspepsia symptoms, five patients (3 f, mean age 38.8±3.2 years) with post-Nissen dysphagia symptoms and 14 pre-fundoplication patients (3 f, mean age 42.1±2.5 years) were evaluated. Patients filled out a Rome II-based dyspepsia symptom severity score, performed a gastric emptying test, and a gastric barostat study was used to evaluate the function of the proximal stomach. KEY RESULTS Upper abdominal bloating scores were higher in post-Nissen dyspepsia patients (P=.016) and symptoms of postprandial distress syndrome (PDS) were more present in post-Nissen dyspepsia patients compared to the other two groups (P=.07). Weight loss was significantly higher in the post-Nissen groups compared to the pre-fundoplication (P=.02). Gastric emptying rates were similar in the three groups. Gastric accommodation (GA) was significantly impaired in the post-Nissen dyspepsia group (dyspepsia -30[-86-83] vs dysphagia 163[148-203] vs pre-fundoplication 147[75-174] mL, P=.004) and the prevalence of patients with impaired GA was higher in the post-Nissen group (P=.007). Postprandial fullness was more prevalent in patients with impaired GA compared to those with normal GA (P=.01). CONCLUSIONS AND INTERFERENCES Patients with post-Nissen dyspepsia show a symptom pattern similar to that in FD patients with PDS, and the main underlying mechanism seems to be impaired gastric accommodation to a meal.

Abstract
A large variety of foregut symptoms can occur in patients with gastroesophageal reflux disease (GERD), which can overlap with other disorders such as somatoform disorders and dyspepsia. Due to unclear diagnostic situations, these patients are often not adequately treated. The aim of this study was the evaluation of patients with foregut symptoms, referred for possible antireflux surgery, regarding their relationship with GERD and somatization tendencies based on control data from an unselected population. Symptom evaluation and somatization screening were initiated both in volunteers and in patients with foregut symptoms and GERD. Unselected volunteers from a village population were also evaluated by symptom analysis and for somatisation tendency. In addition, patients with foregut symptoms were diagnosed for GERD, and symptom analysis and psychodiagnostic evaluation were performed. There is no major significant difference in the symptom-spectrum in patients with foregut symptoms, whether they have a proven pathologic acid exposure from GERD or not. The probability for the risk of somatization was 5.6% in the unselected population of nonpatient volunteers (n = 267). In patients with foregut symptoms (n = 750), the probability for the presence of somatoform tendencies was approximately 20%, independent whether these patients had a documented GERD or a normal esophageal acid exposure, implicating further diagnostic work-up for the selection of patients for antireflux surgery. There is a remarkable symptom load and variety in patients with GERD, in patients with foregut symptoms, and in an unselected population of volunteers. There is no difference in the risk for somatization between patients with foregut symptoms and those with documented GERD. Therapeutic decision making especially prior to antireflux surgery requires an awareness of mental and emotional challenges.

Abstract
The prevalence of abnormal acid gastroesophageal reflux (GER) is higher in patients with idiopathic pulmonary fibrosis (IPF) than in matched control subjects. Several studies demonstrated that more than one-third of patients with IPF have abnormal esophageal acid exposures. In addition, many of these studies indicate that the majority of patients with IPF have silent reflux with no symptoms of GER. Findings of abnormal reflux persist in a large proportion of patients with IPF placed on antacid therapy such as proton pump inhibitors (PPIs). This seemingly paradoxical observation suggests that either patients with IPF are somehow resistant to PPI-based intervention or PPIs are inherently unable to suppress acid GER. By contrast, patients with IPF who undergo Nissen fundoplication surgery are effectively relieved from the complications of GER, and retrospective studies suggest improved lung function. Retrospective, anecdotal data suggest a beneficial role of PPIs in IPF including stabilization of lung function, reduction in episodes of acute exacerbation, and enhanced longevity. The recent evidence-based guidelines for treatment of IPF approved conditional recommendation of PPIs for all patients with IPF regardless of their GER status. Recently, we have reported that PPIs possess antiinflammatory and antifibrotic activities by directly suppressing proinflammatory cytokines, profibrotic proteins, and proliferation of lung fibroblasts. Our study provides an alternative explanation for the beneficial effect of PPIs in IPF. In this Perspective, we reviewed emerging progress on antifibrotic effect of PPIs using IPF as a disease model. In addition, we summarized surgical and pharmacological interventions for GER and their downstream effect on lung physiology.

Abstract
INTRODUCTION Use of the magnetic sphincter augmentation device (MSAD) for gastroesophageal reflux disease (GERD) is increasing. As this innovative treatment for GERD gains widespread use and adoption, an assessment of its safety since U.S. market introduction is presented. METHODS Events were collected from the Manufacturer and User Facility Device Experience (MAUDE) database, which reports events submitted to the Food and Drug Administration (FDA) of suspected device-associated deaths, serious injuries, and malfunctions. The reporting period was from March 22, 2012 (FDA approval) through May 31, 2016, and included only events occurring in the United States. Additional information was provided by the manufacturer, allowing calculation of implant rates and durations. RESULTS An estimated 3283 patients underwent magnetic sphincter augmentation (165 surgeons at 191 institutions). The median implant duration was 1.4 years, with 1016 patients implanted for at least 2 years. No deaths, life-threatening events, or device malfunctions were reported. The overall rate of device removal was 2.7% (89/3283). The most common reasons for device removal were dysphagia (52/89) and persistent reflux symptoms (19/89). Removal for erosion and migration was 0.15% (5/3283) and 0% (0/3283), respectively. There were no perforations. Of the device removals, 57.3% (51/89) occurred <1 year after implant, 30.3% (27/89) between 1 and 2 years, and 12.4% (11/89) >2 years after implant. The rate of device removal and erosion with an implant duration >2 years were 1.1% (11/1016) and 0.1% (1/1016), respectively. All device removals and erosions were managed nonemergently, with no complications or long-term consequences. CONCLUSIONS During a 4-year period in more than 3000 patients, no unanticipated MSAD complications have emerged, and there is no data to suggest a trend of increased events over time. The presentation and management of device-related issues have been less complicated than revisions for laparoscopic fundoplication or other interventions for GERD. MSAD is considered safe for the widespread treatment of GERD.

Temporal patterns of hiatus hernia recurrence and hiatal failure: quality of life and recurrence after revision surgery. Dis Esophagus 2017; 30:1-8. [PMID: 28375479 DOI: 10.1093/dote/dow035] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Accepted: 12/16/2016] [Indexed: 12/11/2022]
Abstract
Antireflux and paraesophageal hernia repair surgery is increasingly performed and there is an increased requirement for revision hiatus hernia surgery. There are no reports on the changes in types of failures and/or the variations in location of crural defects over time following primary surgery and limited reports on the outcomes of revision surgery. The aim of this study is to report the changes in types of hernia recurrence and location of crural defects following primary surgery, to test our hypothesis of the temporal events leading to hiatal recurrence and aid prevention. Quality of life scores following revision surgery are also reported, in one of the largest and longest follow-up series in revision hiatus surgery. Review of a single-surgeon database of all revision hiatal surgery between 1992 and 2015. The type of recurrence and the location of crural defect were noted intraoperatively. Recurrence was diagnosed on gastroscopy and/or contrast study. Quality of life outcomes were measured using Visick, dysphagia, atypical reflux symptoms, satisfaction scores, and Gastrointestinal Quality of Life Index (GIQLI). Two-hundred eighty four patients (126 male, 158 female), median age 60.8(48.2-69.1), underwent revision hiatal surgery. Median follow-up following primary surgery was 122.8(75.3-180.3) and 91.6(40.5-152.5) months after revision surgery. The most common type of hernia recurrence in the early period after primary surgery was 'telescope'(42.9%), but overall, fundoplication apparatus transhiatal migration was consistently the predominant type of recurrence at 1-3 years (54.3%), 3-5 years (42.5%), 5-10 years (45.1%), and >10 years (44.1%). The location of crural defects changed over duration following primary surgery as anteroposterior defects was most common in the early period (45.5% in <1 year) but decreased over time (30.3% at 1-3 years) while anterior defects increased in the long term with 35.9%, 40%, and 42.2% at 3-5 years, 5-10 years, and >10 years, respectively. Revision surgery intraoperative morbidity was 19.7%, mainly gastric (9.5%) and esophageal (2.1%) perforation. There was a 75% follow-up rate and recurrence following revision surgery was 15.4%(44/284) in unscreened population and 21%(44/212) in screened population. There was no difference in recurrence rate based on size of hiatus hernia at primary surgery, or at revision surgery. There were significant improvements in the Visick score (3.3 vs. 2.4), the modified Dakkak score (23.2 vs. 15.4), the atypical reflux symptom score (23.7 vs. 15.4), and satisfaction scores (0.9 vs. 2.2), but no difference in the various domains (symptom, physical, social, and medical) of the GIQLI scores following revision surgery. Revision hiatal surgery has higher intraoperative morbidity but may achieve adequate long-term satisfaction and quality of life. The most common type of early recurrence following primary surgery is telescoping, and overall is wrap herniation. Anterior crural defects may be strong contributor to late hiatus hernia recurrence. Symptom-specific components of GIQLI, but not the overall GIQLI score, may be required to detect improvements in QOL.

Abstract
Laparoscopic antireflux surgery is a frequently performed procedure for the treatment of gastroesophageal reflux in surgical clinics. Reflux can recur in between 3% and 30% of patients on whom antireflux surgery has been performed, and so revision surgery can be required due to recurrent symptoms or dysphagia in approximately 3% to 6% of the patients. The objective of this study is to evaluate the mechanism of recurrences after antireflux surgery and to share our results after revision surgery in recurrent cases.From 2001 to 2014, revision surgery was performed on 43 patients (31 men, 12 women) between the ages of 24 and 70 years. The technical details of the first operation, recurrence symptoms, endoscopy, and manometry findings were evaluated. The findings of revision surgery, surgical techniques, morbidity rates, length of hospitalization, and follow-up period were also recorded and evaluated.The first operation was Nissen fundoplication in 34 patients and Toupet fundoplication in 9 patients. Mesh hiatoplasty was performed for enforcement in 18 (41.9%) of these patients. The period between the first operation and the revision surgery ranged from 4 days to 60 months. The most common finding was slipped fundoplication and presence of hiatal hernia during revision surgery. Revision fundoplication and hernia repair with mesh reinforcement were used in 33 patients. The other techniques were Collis gastroplasty, revision fundoplication, and hernia repair without mesh. The range of follow-up period was from 2 to 134 months. Recurrence occurred in 3 patients after revision surgery (6.9%). Although revision surgery is difficult and it has higher morbidity, it can be performed effectively and safely in experienced centers.

Abstract
With the introduction of laparoscopy, the outcomes of patients undergoing paraesophageal hernia repair have improved dramatically. When the fundamentals of a proper repair are followed, patients can expect to have improvement in gastroesophageal reflux symptoms, including heartburn, regurgitation, chest pain, dysphagia, and dyspnea. Adhering to these principles will alleviate patients' symptoms and avoid reoperation. This article describes the approach to paraesophageal hernia repair, including patient evaluation, operative technique, and postoperative management. Esophageal lengthening and crural reinforcement with mesh are addressed as well. Adhering to the basic techniques outlined in this article should lead to successful and durable patient outcomes following a paraesophageal hernia repair.

Abstract
BACKGROUND This research aims to assess the response to acid suppression therapy in gastroesophageal reflux disease (GERD)-related chronic laryngitis (CL). METHODS Data were extracted from Web of Knowledge, Embase, and PubMed for English language article published up to March 2016. Pooled overall response rate (ORR) rates were evaluated to determine acid suppression treatment efficacy. Random effects model was used with standard approaches to sensitivity analysis, quality assessment, heterogeneity, and exploration of publication bias. RESULTS Pooled data from 21 reports (N = 2864, antireflux medicine: 2741; antireflux surgery: 123, study duration 4-108 week) were analyzed. With the random-effect model, the ORR was 66% (95% confidence interval [CI] 54%-78%). The ORRs were 80% for antireflux surgery (95% CI 67%-93%, 3 studies, 123 patients), whereas 64% for antireflux medicine (95% CI 50%-77%, 18 studies, 2741 patients), and the ORR was 70% (95% CI 55%-85%, 15 reports, 2731 patients) for >8 weeks' therapy duration, whereas 57% (95% CI 48%-65%, 6 reports, 133 patients) for ≤8 weeks' duration of therapy. CONCLUSIONS Acid suppression seems to be an effective therapy for GERD-related CL. There was an increase in effect among patients with surgery therapeutic method and longer therapy duration.

Abstract
Laparoscopic antireflux surgery is an effective treatment for patients with gastro-esophageal reflux disease, when it is refractory to conservative management. In experienced centers the procedure is safe, although complications may develop either during surgery or in the early or late postoperative period, which may necessitate revisional surgery. Between 1998 and 2015 a total of 407 patients underwent laparoscopic antireflux surgery at the Department of Surgery, University of Pécs. This interval was divided into two periods. In the first one, between 1998 and 2006, we operated on 241 patients who were all enrolled in a prospective study. All the diagnostic examinations were carried out at our institution. In the second period 166 patients were treated with minimal invasive surgery and the data were analyzed retrospectively. The 407 patients comprised 161 men and 246 women with a median age of 53,1 years. Hiatoplasty was reinforced with teres ligament in 27 cases, a prosthetic mesh was used in 28 cases and fascia lata in a four cases, when hiatal closures were not considered reliable. In 16 cases (4%) the operation was converted to open procedure, and our mortality rate was 0,5%. Revisional surgery was performed laparoscopically in 39 patients, and thoraco-laparotomy was done in six cases (12%). 5 additional reoperations were performed in patients, who had their primary antireflux surgery in another institution. Our 4% conversion, 12% reoperation and 0,5% mortality rates correspond to the figures published in the literature. In conclusion, this study confirms that laparoscopic antireflux surgery is a safe procedure with very good clinical outcomes. Late complications, such as recurrent reflux disease and reherniation, as well as revisional surgery occured almost exclusively after surgical treatment of the large hiatal hernias.

Abstract
Patients experiencing heartburn and acid regurgitation despite proton pump inhibition therapy who are averse to antireflux surgery fall into what is called the gastroesophageal reflux disease (GERD) treatment gap. This gap may be potentially addressed by several endoscopic and laparoscopic techniques, including gastric bypass surgery for those patients who are obese. These novel techniques do not significantly alter the anatomy of the esophagogastric junction, minimizing short- and long-term adverse effects. This review provides an overview of the assessment of patients with refractory GERD and highlights the strengths and weaknesses of these minimally invasive therapies.

Abstract
BACKGROUND Esophagogastric junction contractile integral (EGJ-CI) assesses EGJ barrier function on esophageal high resolution manometry (HRM). We assessed EGJ-CI values in achalasia and gastroesophageal reflux disease (GERD) to determine if postoperative EGJ-CI changes reflected surgical intervention. METHODS Twenty-one achalasia patients (42.8 ± 3.2 years, 62% F) with HRM before and after Heller myotomy (HM) and 68 GERD patients (53.9 ± 1.8 years, 66% F) undergoing antireflux surgery (ARS) were compared to 21 healthy controls (27.6 ± 0.6 years, 52% F). Esophagogastric junction contractile integral (mmHg.cm) was calculated using the distal contractile integral measurement across the EGJ, measured above the gastric baseline and corrected for respiration. Pre and postsurgical EGJ-CI and conventional lower esophageal sphincter pressure (LESP) metrics were compared within and between these groups using non-parametric tests. Correlation between EGJ-CI and conventional LESP metrics was assessed. KEY RESULTS Baseline EGJ-CI was higher in achalasia compared to GERD (p < 0.001) or controls (p = 0.03). Esophagogastric junction contractile integral declined by 59.2% after HM in achalasia (p = 0.001), and increased by 26.3% after ARS in GERD (p = 0.005). End-expiratory and basal LESP decreased by 74.5% and 64.5% with HM, but increased by only 17.8% and 4.3% with ARS. Differences were noted between Dor vs Toupet fundoplication in achalasia (p = 0.007), and partial vs complete ARS in GERD (p = 0.03). Esophagogastric junction contractile integral correlated modestly with both end-expiratory and basal LESP (Pearson's r of 0.8 for all), but was less robust in GERD (0.7). CONCLUSIONS & INFERENCES Esophagogastric junction contractile integral has clinical utility in assessing EGJ barrier function at baseline and after surgical intervention to the EGJ, and could complement conventional EGJ metrics.

Incidence of true short esophagus among patients submitted to laparoscopic Nissen fundoplication. Wideochir Inne Tech Maloinwazyjne 2015; 10:10-4.

Abstract
Introduction The last two decades have observed development of surgical treatment of benign conditions of the gastroesophageal junction (GEJ), including anti-reflux surgery, due to the growing popularity of the laparoscopic approach. Migration of the fundoplication band and recurrent hiatal hernia are a result of the lack of correct diagnosis and appropriate management of the so-called short esophagus. According to various authors, short esophagus is present in up to 60% of patients qualified for anti-reflux surgery. However, some researchers question the existence of this condition. Aim To analyze the prevalence of short esophagus in patients subjected to laparoscopic Nissen fundoplication. Material and methods The study included 202 patients who were subjected to laparoscopic Nissen fundoplication. Results As many as 96% of the patients qualified for the surgical treatment showed supradiaphragmatic location of the high pressure zone. The extent of GEJ protrusion ranged from 0 cm to 3 cm (mean: 2 cm). The extent of dissection within the mediastinum was determined by the level of GEJ protrusion, and ranged from 5 cm to 12 cm (mean: 6 cm). Upon complete mobilization of the esophagus within the mediastinum, no cases of significantly shortened esophagus, precluding downward retraction of at least a 2.5-cm segment below the diaphragmatic crura, were documented. Therefore, none of the patients required Collis gastroplasty. Conclusions The presence of “true” short esophagus is a sporadic finding among patients qualified for anti-reflux surgery. Mediastinal dissection of the esophagus and its mobilization at an appropriate, individually defined level seems a sufficient treatment in the vast majority of these patients.

Current Diagnosis and Management of Suspected Reflux Symptoms Refractory to Proton Pump Inhibitor Therapy. Gastroenterol Hepatol (N Y) 2014; 10:547-555.

Abstract
Suspected reflux symptoms that are refractory to proton pump inhibitors (PPIs) are rapidly becoming the most common presentation of gastroesophageal reflux disease (GERD) in patients seen in gastroenterology clinics. These patients are a heterogeneous group, differing in symptom frequency and severity, PPI dosing regimens, and responses to therapy (from partial to absent). Before testing, the physician needs to question the patient carefully about PPI compliance and the timing of drug intake in relation to meals. Switching PPIs or doubling the dose is the next step, but only 20% to 25% of the group refractory to PPIs will respond. The first diagnostic test should be upper gastrointestinal endoscopy. In more than 90% of cases, the results will be normal, but persistent esophagitis may suggest pill esophagitis, eosinophilic esophagitis, or rarer diseases, such as lichen planus, Zollinger-Ellison syndrome, or genotype variants of PPI metabolism. If the endoscopy results are normal, esophageal manometry and especially reflux testing should follow. Whether patients should be tested on or off PPI therapy is controversial. Most physicians prefer to test patients off PPIs to identify whether abnormal acid reflux is even present; if it is not, PPIs can be stopped and other diagnoses sought. Testing patients on PPI therapy allows nonacid reflux to be identified, but more than 50% of patients have a normal test result, leaving the clinician with a conundrum-whether to stop PPIs or continue them because the GERD is being treated adequately. Alternative diagnoses in patients with refractory GERD and normal reflux testing include achalasia, eosinophilic esophagitis, gastroparesis, rumination, and aerophagia. However, more than 50% will be given the diagnosis of functional heartburn, a visceral hypersensitivity syndrome. Treating patients with PPI-refractory GERD-like symptoms can be difficult and frustrating. Any of the following may help: a histamine-2 receptor antagonist at night, baclofen to decrease transient lower esophageal sphincter relaxations, pain modulators, acupuncture, or hypnotherapy. At this time, antireflux surgery should be limited to patients with abnormal acid reflux defined by pH testing and a good correlation of symptoms with acid reflux.

Abstract
BACKGROUND Robot-assisted general surgery operations are being performed more frequently. This review investigates whether robotic assistance results in significant advantages or disadvantages for the operative treatment of gastro-oesophageal reflux disease and achalasia. METHODS The electronic databases (Medline, Embase, PubMed) were searched for original English language publications for antireflux surgery and Heller's myotomy between January 1990 and December 2013. RESULTS Thirty-three publications included antireflux operations and 20 included Heller's myotomy. The publications indicate that the safety and effectiveness of robotic surgery is similar to that of conventional minimally invasive surgery for both operations. The six randomized trials of robot-assisted versus laparoscopic antireflux surgery showed no significant advantages but significantly higher costs for the robotic method. Gastric perforation during non-redo robotic fundoplication occurred in four trials. CONCLUSIONS No consistent advantage for robot-assisted antireflux surgery has been demonstrated, and there is an increased cost with current robotic technology. A reported advantage for robotic in reducing the perforation rate during Heller's myotomy for achalasia remains unproven. Gastric perforation during robotic fundoplication may be due to the lack of haptic feedback combined with the superhuman strength of the robot.

Abstract
Antireflux surgery with a magnetic sphincter augmentation device (MSAD) restores the competency of the lower esophageal sphincter with a device rather than a tissue fundoplication. As a regulated device, safety information from the published clinical literature can be supplemented by tracking under the Safe Medical Devices Act. The aim of this study was to examine the safety profile of the MSAD in the first 1000 implanted patients. We compiled safety data from all available sources as of July 1, 2013. The analysis included intra/perioperative complications, hospital readmissions, procedure-related interventions, reoperations, and device malfunctions leading to injury or inability to complete the procedure. Over 1000 patients worldwide have been implanted with the MSAD at 82 institutions with median implant duration of 274 days. Event rates were 0.1% intra/perioperative complications, 1.3% hospital readmissions, 5.6% endoscopic dilations, and 3.4% reoperations. All reoperations were performed non-emergently for device removal, with no complications or conversion to laparotomy. The primary reason for device removal was dysphagia. No device migrations or malfunctions were reported. Erosion of the device occurred in one patient (0.1%). The safety analysis of the first 1000 patients treated with MSAD for gastroesophageal reflux disease confirms the safety of this device and the implantation technique. The overall event rates were low based on data from 82 institutions. The MSAD is a safe therapeutic option for patients with chronic, uncomplicated gastroesophageal reflux disease.

The effects and efficacy of antireflux surgery in children with gastroesophageal reflux disease: a systematic review. J Gastrointest Surg 2011; 15:1872-8.

Abstract
BACKGROUND Antireflux surgery (ARS) for gastroesophageal reflux disease (GERD) is one of the most frequently performed major operations in children. Many studies have described the results of ARS in children, however, with a wide difference in outcome. This study aims to systematically review the efficacy of pediatric ARS and its effects on gastroesophageal function, as measured by gastroesophageal function tests. This is the first systematic review comprising only prospective, longitudinal studies, minimizing the risk of bias. METHODS Three electronic databases (Medline, Embase, and the Cochrane Library) were searched for prospective studies reporting on ARS in children with GERD. RESULTS In total, 17 eligible studies were identified, reporting on a total of 1,280 children. The median success rate after ARS was 86% (57-100%). The success rate in neurologically impaired children was worse in one study, but similar in another study compared to normally developed children. Different surgical techniques (total versus partial fundoplication, or laparoscopic versus open approach) showed similar reflux recurrence rates. However, less postoperative dysphagia was observed after partial fundoplication and laparoscopic ARS was associated with less pain medication and a shorter hospital stay. Complications of ARS varied from minimal postoperative complications to severe dysphagia and gas bloating. The reflux index (RI), obtained by 24-h pH monitoring (n = 8) decreased after ARS. Manometry, as done in three studies, showed no increase in lower esophageal sphincter pressure after ARS. Gastric emptying (n = 3) was reported either unchanged or accelerated after ARS. No studies reported on barium swallow x-ray, endoscopy, or multichannel intraluminal impedance monitoring before and after ARS. CONCLUSION ARS in children shows a good overall success rate (median 86%) in terms of complete relief of symptoms. Efficacy of ARS in neurologically impaired children may be similar to normally developed children. The outcome of ARS does not seem to be influenced by different surgical techniques, although postoperative dysphagia may occur less after partial fundoplication. However, these conclusions are bound by the lack of high-quality prospective studies on pediatric ARS. Similar studies on the effects of pediatric ARS on gastroesophageal function are also very limited. We recommend consistent use of standardized assessment tests to clarify the effects of ARS on gastroesophageal function and to identify possible risk factors for failure of ARS in children.

[PMID: 19347410 PMCID: PMC2710493 DOI: 10.1007/s11605-009-0873-z] [Citation(s) in RCA: 148] [Impact Index Per Article: 9.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2008] [Accepted: 03/12/2009] [Indexed: 02/06/2023]
Abstract
BACKGROUND Outcome and morbidity of redo antireflux surgery are suggested to be less satisfactory than those of primary surgery. Studies reporting on redo surgery, however, are usually much smaller than those of primary surgery. The aim of this study was to summarize the currently available literature on redo antireflux surgery. MATERIAL AND METHODS A structured literature search was performed in the electronic databases of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials. RESULTS A total of 81 studies met the inclusion criteria. The study design was prospective in 29, retrospective in 15, and not reported in 37 studies. In these studies, 4,584 reoperations in 4,509 patients are reported. Recurrent reflux and dysphagia were the most frequent indications; intraoperative complications occurred in 21.4% and postoperative complications in 15.6%, with an overall mortality rate of 0.9%. The conversion rate in laparoscopic surgery was 8.7%. Mean(+/-SEM) duration of surgery was 177.4 +/- 10.3 min and mean hospital stay was 5.5 +/- 0.5 days. Symptomatic outcome was successful in 81.1% and was equal in the laparoscopic and conventional approach. Objective outcome was obtained in 24 studies (29.6%) and success was reported in 78.3%, with a slightly higher success rate in case of laparoscopy than with open surgery (85.8% vs. 78.0%). CONCLUSION This systematic review on redo antireflux surgery has confirmed that morbidity and mortality after redo surgery is higher than after primary surgery and symptomatic and objective outcome are less satisfactory. Data on objective results were scarce and consistency with regard to reporting outcome is necessary.

Abstract
Gastroesophageal reflux disease has different clinical presentations that require different diagnostic and therapeutic approaches. This paper describes the appropriate use of diagnostic tests before and after treatment. Each diagnostic tool is examined from a practical point of view to determine the information it can provide and its possible pitfalls, and to comment on how it can influence therapeutic choices. Performing a preoperative diagnostic evaluation is especially stressed, so as not to select the wrong patient or the wrong procedure. Finally, failures of surgery are examined to understand their causes and to prevent them. The value of the most relevant examinations for diagnosing the causes of failures and choosing the appropriate solution are discussed.
