RESUMEN
Background: Eosinophilic esophagitis (EoE) is recognized as a chronic type 2 inflammatory disease characterized by the eosinophilic infiltration of the esophageal tissue, posing a significant disease burden and highlighting the necessity for novel management strategies to address unmet clinical needs. Objectives: To critically evaluate the existing literature on the epidemiology and management of EoE, identify evidence gaps, and assess the efficacy of current and emerging treatment modalities. Design: An extensive literature review was conducted, focusing on the epidemiological trends, diagnostic challenges, and therapeutic interventions for EoE. This was complemented by a survey among physicians and consultations with a scientific expert panel, including a patient's association (ESEO Italia), to enrich the study findings. Data sources and methods: The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, scrutinizing epidemiological studies and management research to compile comprehensive insights into the disease's landscape. The physician survey and expert panel discussions aimed to bridge identified evidence gaps. Results: The review included 59 epidemiological and 51 management studies, uncovering variable incidence and prevalence rates of EoE globally, with an estimated diagnosed prevalence of 41 per 100,000 in Italy. Diagnostic challenges were identified, including nonspecific symptoms and the lack of definitive biomarkers, which complicate the use of endoscopy. Treatment options such as elimination diets, proton-pump inhibitors, and swallowed corticosteroids were found to have varying success rates, while Dupilumab, an emerging therapy targeting interleukin (IL)-4 and IL-13, shows promise. Conclusion: Despite advancements in understanding and managing EoE, significant unmet clinical needs remain, particularly in biomarker identification, therapy personalization, and cost-effectiveness evaluation. A comprehensive, multidimensional approach to patient management is required, emphasizing the importance of early symptom recognition, accurate diagnosis, and tailored treatment strategies. Dupilumab offers potential as a novel treatment, underscoring the need for future research to explore the economic and social dimensions of EoE care pathways.
Understanding and improving care for eosinophilic esophagitis: bridging gaps in diagnosis and treatment Eosinophilic esophagitis (EoE) is a chronic inflammatory condition affecting the esophagus. We reviewed studies on how common EoE is and how it's managed. In Italy, about 41 out of 100,000 people may have it. Diagnosis can be tricky due to vague symptoms, and current treatments vary in effectiveness. We found a need for better ways to diagnose and treat EoE, including exploring new therapies. A promising development is a biologic called Dupilumab. Future research should also consider the costs and social aspects of caring for people with EoE.
RESUMEN
OBJECTIVE: A definitive diagnosis of gastroesophageal reflux disease (GERD) depends on endoscopic and/or pH-study criteria. However, high resolution manometry (HRM) can identify factors predicting GERD, such as ineffective esophageal motility (IEM), esophago-gastric junction contractile integral (EGJ-CI), evaluating esophagogastric junction (EGJ) type and straight leg raise (SLR) maneuver response. We aimed to build and externally validate a manometric score (Milan Score) to stratify the risk and severity of the disease in patients undergoing HRM for suspected GERD. METHODS: A population of 295 consecutive patients undergoing HRM and pH-study for persistent typical or atypical GERD symptoms was prospectively enrolled to build a model and a nomogram that provides a risk score for AET > 6%. Collected HRM data included IEM, EGJ-CI, EGJ type and SLR. A supplemental cohort of patients undergoing HRM and pH-study was also prospectively enrolled in 13 high-volume esophageal function laboratories across the world in order to validate the model. Discrimination and calibration were used to assess model's accuracy. Gastroesophageal reflux disease was defined as acid exposure time >6%. RESULTS: Out of the analyzed variables, SLR response and EGJ subtype 3 had the highest impact on the score (odd ratio 18.20 and 3.87, respectively). The external validation cohort consisted of 233 patients. In the validation model, the corrected Harrel c-index was 0.90. The model-fitting optimism adjusted calibration slope was 0.93 and the integrated calibration index was 0.07, indicating good calibration. CONCLUSIONS: A novel HRM score for GERD diagnosis has been created and validated. The MS might be a useful screening tool to stratify the risk and the severity of GERD, allowing a more comprehensive pathophysiologic assessment of the anti-reflux barrier. TRIAL REGISTRATION: ClinicalTrials.gov (Identifier: NCT05851482).

BACKGROUND: The diagnosis of gastro-oesophageal reflux disease (GERD) based on otolaryngologist's assessment of laryngoscopic findings remains contentious in terms of sensitivity and specificity. AIMS: To evaluate GERD prevalence, applying Lyon 2.0 Consensus criteria, in patients with extra-oesophageal symptoms undergoing laryngoscopic examination and impedance-pH monitoring. METHODS: In this retrospective assessment, we included 470 patients with extra-oesophageal symptoms, either isolated or combined with typical symptoms, who had been referred to six tertiary Italian Gastroenterology Units between January and December 2020. Of these, 274 underwent 24-h impedance-pH monitoring and laryngoscopy off PPI therapy. GERD diagnosis followed Lyon Consensus 2.0 criteria, incorporating mean nocturnal baseline impedance when pH-impedance monitoring was inconclusive. RESULTS: Laryngoscopic examination revealed pathological findings (predominantly posterior laryngitis) in 71.2% (195/274). GERD was diagnosed in 29.2% (80/274) via impedance-pH monitoring. The prevalence of GERD in patients with positive or negative laryngoscopy was similar (32.3% vs. 21.5%, p = 0.075). No significant difference in proximal reflux occurrences was noted between positive and negative laryngoscopy groups (33.3% vs. 24.1%, p = 0.133). Laryngoscopy demonstrated sensitivity and specificity of 78.8% and 32.0%, respectively, with a positive predictive value (PPV) of 32.3% and negative predictive value (NPV) of 28.4%. In contrast, a threshold of four concurrent laryngoscopic signs, identified in only eight patients, demonstrated a PPV of 93.8% and a NPV of 73.6% (sensitivity 25.4%, specificity 99.2%). CONCLUSION: This study underscores the limited diagnostic accuracy of laryngoscopy, emphasising the necessity of impedance-pH monitoring for confirming GERD diagnoses using Lyon 2.0 criteria in patients with suspected extra-oesophageal symptoms.

The present document constitutes Part 2 of the EoETALY Consensus Statements guideline on the diagnosis and management of eosinophilic esophagitis (EoE) developed by experts in the field of EoE across Italy (i.e., EoETALY Consensus Group). Part 1 was published as a different document, and included three chapters discussing 1) definition, epidemiology, and pathogenesis; 2) clinical presentation and natural history and 3) diagnosis of EoE. The present work provides guidelines on the management of EoE in two final chapters: 4) treatment and 5) monitoring and follow-up, and also includes considerations on knowledge gaps and a proposed research agenda for the coming years. The guideline was developed through a Delphi process, with grading of the strength and quality of the evidence of the recommendations performed according to accepted GRADE criteria.This document has received the endorsement of three Italian national societies including the Italian Society of Gastroenterology (SIGE), the Italian Society of Neurogastroenterology and Motility (SINGEM), and the Italian Society of Allergology, Asthma, and Clinical Immunology (SIAAIC). The guidelines also involved the contribution of members of ESEO Italia, the Italian Association of Families Against EoE.

Eosinophilic esophagitis (EoE) is a chronic type 2-mediated inflammatory disease of the esophagus that represents the most common eosinophilic gastrointestinal disease. Experts in the field of EoE across Italy (i.e., EoETALY Consensus Group) including gastroenterologists, endoscopists, allergologists/immunologists, and paediatricians conducted a Delphi process to develop updated consensus statements for the management of patients with EoE and update the previous position paper of the Italian Society of Gastroenterology (SIGE) in light of recent evidence. Grading of the strength and quality of the evidence of the recommendations was performed using accepted GRADE criteria. The guideline is divided in two documents: Part 1 includes three chapters, namely 1) definition, epidemiology, and pathogenesis; 2) clinical presentation and natural history, and 3) diagnosis, while Part 2 includes two chapters: 4) treatment and 5) monitoring and follow-up. This document has received the endorsement of three Italian national societies including the SIGE, the Italian Society of Neurogastroenterology and Motility (SINGEM), and the Italian Society of Allergology, Asthma, and Clinical Immunology (SIAAIC). With regards to patients' involvement, these guidelines involved the contribution of members of ESEO Italia, the Italian Association of Families Against EoE.

GOALS: Develop quality indicators for ineffective esophageal motility (IEM). BACKGROUND: IEM is identified in up to 20% of patients undergoing esophageal high-resolution manometry (HRM) based on the Chicago Classification. The clinical significance of this pattern is not established and management remains challenging. STUDY: Using RAND/University of California, Los Angeles Appropriateness Methods, we employed a modified-Delphi approach for quality indicator statement development. Quality indicators were proposed based on prior literature. Experts independently and blindly scored proposed quality statements on importance, scientific acceptability, usability, and feasibility in a 3-round iterative process. RESULTS: All 10 of the invited esophageal experts in the management of esophageal diseases invited to participate rated 12 proposed quality indicator statements. In round 1, 7 quality indicators were rated with mixed agreement, on the majority of categories. Statements were modified based on panel suggestion, modified further following round 2's virtual discussion, and in round 3 voting identified 2 quality indicators with comprehensive agreement, 4 with partial agreement, and 1 without any agreement. The panel agreed on the concept of determining if IEM is clinically relevant to the patient's presentation and managing gastroesophageal reflux disease rather than the IEM pattern; they disagreed in all 4 domains on the use of promotility agents in IEM; and had mixed agreement on the value of a finding of IEM during anti-reflux surgical planning. CONCLUSION: Using a robust methodology, 2 IEM quality indicators were identified. These quality indicators can track performance when physicians identify this manometric pattern on HRM. This study further highlights the challenges met with IEM and the need for additional research to better understand the clinical importance of this manometric pattern.
RESUMEN
BACKGROUND: Mechanisms underlying perception of dysphagia and chest pain have not been completely elucidated, although oesophageal mucosal afferent nerves might play an important role. AIMS: To evaluate the relationship between oesophageal mucosal afferent nerves and the severity of dysphagia and chest pain in oesophageal motility disorders. METHODS: We prospectively recruited patients with oesophageal motility disorders having dysphagia and/or chest pain from whom oesophageal biopsies were obtained. High-resolution manometry classified patients into disorders of oesophagogastric junction (OGJ) outflow and disorders of peristalsis. Symptom severity was assessed using validated questionnaires including Brief Oesophageal Dysphagia Questionnaire (BEDQ). Immunohistochemistry was performed on oesophageal biopsies to evaluate the location of calcitonin gene-related peptide (CGRP)-immunoreactive mucosal afferent nerves. Findings were compared to existing data from 10 asymptomatic healthy volunteers. RESULTS: Of 79 patients, 61 patients had disorders of OGJ outflow and 18 had disorders of peristalsis. CGRP-immunoreactive mucosal nerves were more superficially located in the mucosa of patients with oesophageal motility disorders compared to healthy volunteers. Within disorders of OGJ outflow, the location of CGRP-immunoreactive nerves negatively correlated with BEDQ score both in the proximal (ρ = -0.567, p < 0.001) and distal oesophagus (ρ = -0.396, p = 0.003). In the proximal oesophagus, strong chest pain was associated with more superficially located mucosal nerves than weak chest pain (p = 0.04). Multivariate analysis showed superficial nerves in the proximal oesophagus was independently associated with severe dysphagia in disorders of OGJ outflow (p = 0.008). CONCLUSIONS: Superficial location of mucosal nerves in the proximal oesophagus might contribute to symptoms, especially severe dysphagia, in disorders of OGJ outflow.

Background: Videocapsule endoscopy (VCE) and double-balloon enteroscopy (DBE) are part of the diagnostic and therapeutic work-up of indications other than suspected small bowel bleeding (OSBB). The literature is currently lacking studies describing these procedures in this particular setting. Objectives: We assessed the clinical impact of VCE and DBE in a large monocentric cohort of OSBB patients, as compared to a control group of suspected small bowel bleeding (SSBB) patients who underwent enteroscopy over the same period. Design: Monocentric, retrospective, cohort study. Methods: We collected the data of consecutive patients with OSBB undergoing VCE and/or DBE from March 2001 to July 2020. The demographic and clinical parameters of the patients, technical characteristics, and adverse events for each procedure were collected. The impact of VCE and DBE was defined in terms of diagnostic yield (DY). The patients were subdivided according to the main indication into four groups: celiac disease, Crohn's disease (CD), neoplasia, and persistent gastrointestinal symptoms. Results: A total of 611 VCEs and 387 DBEs were performed for OSBB. The main indications were complicated celiac disease and CD. The DYs of VCE and DBE overall were 53 and 61.7%, respectively, with some variance among the four groups. We report no statistical differences in the DY of VCE and DBE in SSBB vs OSBB (57.7% vs 53%, p = 0.0859 and 68.8% vs 61.7%, p = 0.0582, respectively). OSBB patients were significantly younger than those with SSBB. However, similarly to SSBB (k = 0.059), poor agreement between the enteroscopic techniques was found in the OSBB population (k = 0.109). The safety of both procedures in OSBB was comparable to that in SSBB patients. Conclusion: VCE and DBE are effective and safe in suspected OSBB, where their role is similar to that in SSBB, their main indication.
RESUMEN
BACKGROUND: Question prompt lists (QPLs) are structured sets of disease-specific questions, intended to encourage question-asking by patients and enhance patient-physician communication. To date, a dysphagia-specific QPL has not been developed for patients with esophageal dysphagia symptoms. We aim to develop a dysphagia-specific QPL incorporating both esophageal expert and patient perspectives, applying rigorous methodology. METHODS: The QPL content was generated applying a two-round modified Delphi (RAND/UCLA) method among 11 experts. In round one, experts provided five answers to the prompts: "What general questions should patients ask when being seen for dysphagia?" and "What questions do I not hear patients asking but, given my experience, I believe they should be asking?" In round two, experts rated proposed questions on a 5-point Likert scale. Responses rated as "essential" or "important", determined by an a priori median threshold of ≥4.0, were accepted for inclusion. Subsequently, 20 patients from Stanford Health Care were enrolled to modify the preliminary QPL, to incorporate their perspectives and opinions. Patients independently rated questions applying the same 5-point Likert scale. At the end, patients were encouraged to propose additional questions to incorporate into the QPL by open-endedly asking "Are there questions we didn't ask, that you think we should?" KEY RESULTS: Eleven experts participated in both voting rounds. Of 85 questions generated from round one, 60 (70.6%) were accepted for inclusion, meeting a median value of ≥4.0. Questions were combined to reduce redundancy, narrowing down to 44 questions. Questions were categorized into the following six themes: 1. "What is causing my dysphagia?"; 2. "Associated symptoms"; 3. "Testing for dysphagia"; 4. "Lifestyle modifications"; 5. "Treatment for dysphagia"; and 6. "Prognosis". The largest number of questions covered "What is causing my dysphagia" (27.3%). Twenty patients participated and modified the QPL. Of the 44 questions experts agreed were important, only 30 questions (68.2%) were accepted for inclusion. Six patients proposed 10 additional questions and after incorporating the suggested questions, the final dysphagia-specific QPL created by esophageal experts and modified by patients consisted of 40 questions. CONCLUSIONS & INFERENCES: Incorporating expert and patient perspectives, we developed a dysphagia-specific QPL to enhance patient-physician communication. Our study highlights importance of incorporating patient perspective when developing such a communication tool. Further studies will measure the impact of this communication tool on patient engagement.

PURPOSE: Garlic consumption has been inversely associated to intestinal adenoma (IA) and colorectal cancer (CRC) risk, although evidence is not consistent. Gut microbiota has been implied in CRC pathogenesis and is also influenced by garlic consumption. We analyzed whether dietary garlic influence CRC risk and bacterial DNA in blood. METHODS: We conducted a case-control study in Italy involving 100 incident CRC cases, 100 IA and 100 healthy controls matched by center, sex and age. We used a validated food frequency questionnaire to assess dietary habits and garlic consumption. Blood bacterial DNA profile was estimated using qPCR and16S rRNA gene profiling. We derived odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) of IA and CRC according to garlic consumption from multiple conditional logistic regression. We used Mann-Whitney and chi-square tests to evaluate taxa differences in abundance and prevalence. RESULTS: The OR of CRC for medium/high versus low/null garlic consumption was 0.27 (95% CI = 0.11-0.66). Differences in garlic consumption were found for selected blood bacterial taxa. Medium/high garlic consumption was associated to an increase of Corynebacteriales order, Nocardiaceae family and Rhodococcus genus, and to a decrease of Family XI and Finegoldia genus. CONCLUSIONS: The study adds data on the protective effect of dietary garlic on CRC risk. Moreover, it supports evidence of a translocation of bacterial material to bloodstream and corroborates the hypothesis of a diet-microbiota axis as a mechanism behind the role of garlic in CRC prevention.

INTRODUCTION: The Lyon Consensus designates Los Angeles (LA) grade C/D esophagitis or acid exposure time (AET) >6% on impedance-pH monitoring (MII-pH) as conclusive for gastroesophageal reflux disease (GERD). We aimed to evaluate proportions with objective GERD among symptomatic patients with LA grade A, B, and C esophagitis on endoscopy. METHODS: Demographics, clinical data, endoscopy findings, and objective proton-pump inhibitor response were collected from symptomatic prospectively enrolled patients from 2 referral centers. Off-therapy MII-pH parameters included AET, number of reflux episodes, mean nocturnal baseline impedance, and postreflux swallow-induced peristaltic wave index. Objective GERD evidence was compared between LA grades. RESULTS: Of 155 patients (LA grade A: 74 patients, B: 61 patients, and C: 20 patients), demographics and presentation were similar across LA grades. AET >6% was seen in 1.4%, 52.5%, and 75%, respectively, in LA grades A, B, and C. Using additional MII-pH metrics, an additional 16.2% with LA grade A and 47.5% with LA grade B esophagitis had AET 4%-6% with low mean nocturnal baseline impedance and postreflux swallow-induced peristaltic wave index; there were no additional gains using the number of reflux episodes or symptom-reflux association metrics. Compared with LA grade C (100% conclusive GERD based on endoscopic findings), 100% of LA grade B esophagitis also had objective GERD but only 17.6% with LA grade A esophagitis ( P < 0.001 compared with each). Proton-pump inhibitor response was comparable between LA grades B and C (74% and 70%, respectively) but low in LA grade A (39%, P < 0.001). DISCUSSION: Grade B esophagitis indicates an objective diagnosis of GERD.

BACKGROUND & AIMS: Incomplete esophageal emptying is a key variable predicting symptom relapse after achalasia treatment. Although optimally evaluated using the timed barium esophagogram (TBE), incomplete esophageal emptying can also be identified on rapid drink challenge (RDC) performed during high-resolution manometry. METHODS: We evaluated if RDC differentiates complete from incomplete esophageal emptying in treated patients with achalasia, against a TBE gold standard. Unselected treated patients with achalasia with both TBE (200 mL of low-density barium suspension) and RDC (200 mL of water in sitting position) were enrolled in 5 tertiary referral centers. TBE barium column height at 1, 2, and 5 minutes were compared with RDC variables: pressurizations >20 mmHg, maximal RDC pressurization, proportion of RDC time occupied by pressurizations, trans-esophagogastric junction gradient, and integrated relaxation pressure. RESULTS: Of 175 patients recruited (mean age, 59 years; 47% female), 138 (79%) were in clinical remission. Complete TBE emptying occurred in 45.1% at 1 minute, 64.0% at 2 minutes, and 73.1% at 5 minutes. RDC integrated relaxation pressure correlated strongly with TBE column height, and a 10-mmHg threshold discriminated complete from incomplete emptying at all 3 TBE time points with area under receiver operating characteristic curves of 0.85, 0.87, and 0.85, respectively. This threshold had high negative predictive values for complete emptying (88% at 2 minutes, 94% at 5 minutes), and modest positive predictive values for incomplete emptying (77% at 2 minutes, 62% at 5 minutes). CONCLUSIONS: RDC during high-resolution manometry is an effective surrogate for TBE in assessing esophageal emptying in treated patients with achalasia.

BACKGROUND: Question prompt lists (QPLs) are structured sets of disease-specific questions that enhance patient-physician communication by encouraging patients to ask questions during consultations. AIM: The aim of this study was to develop a preliminary achalasia-specific QPL created by esophageal experts. METHODS: The QPL content was derived through a modified Delphi method consisting of 2 rounds. In round 1, experts provided 5 answers to the prompts "What general questions should patients ask when given a new diagnosis of achalasia" and "What questions do I not hear patients asking, but given my expertise, I believe they should be asking?" In round 2, experts rated questions on a 5-point Likert scale. Questions considered "essential" or "important" were accepted into the QPL. Feedback regarding the QPL was obtained in a pilot study wherein patients received the QPL before their consultation and completed surveys afterwards. RESULTS: Nineteen esophageal experts participated in both rounds. Of 148 questions from round 1, 124 (83.8%) were accepted into the QPL. These were further reduced to 56 questions to minimize redundancy. Questions were categorized into 6 themes: "What is achalasia," "Risks with achalasia," "Symptom management in achalasia," "Treatment of achalasia," "Risk of reflux after treatment," and "Follow-up after treatment." Nineteen patients participated in the pilot, most of whom agreed that the QPL was helpful (84.2%) and recommended its wider use (84.2%). CONCLUSIONS: This is the first QPL developed specifically for adults with achalasia. Although well-received in a small pilot, follow-up studies will incorporate additional patient feedback to further refine the QPL content and assess its usability, acceptability, and feasibility.

BACKGROUND AND AIMS: To investigate the effectiveness of double-balloon enteroscope-assisted retrograde cholangiopancreatography (DBE-ERCP) in patients with gastrointestinal surgically altered anatomy (SAA). METHODS: From May 2013 to October 2021, all consecutive patients undergoing DBE-ERCP in three gastroenterological referral centers in Northern Italy were enrolled in the study. Patients were assessed regarding their medical history, previous surgery, time from previous surgery to the DBE-ERCP procedure, and the success or failure of DBE-ERCP. RESULTS: Fifty-three patients (60% men, median age 65 (23-89) years) undergoing 67 DBE-ERCP procedures (1-3 DBE-ERCP per patient) were enrolled. Reasons for SAA included orthotopic liver transplantation (23%), ulcers (15%), malignancies (43%), difficult cholecystectomy (17%), and other causes (2%). Types of surgery included Roux-en-Y biliodigestive anastomosis (45%), Roux-en-Y gastrectomy (32%), pancreaticoduodenectomy (17%), and Billroth II gastrectomy (6%). The overall DBE-ERCP success rate was 86%. The type of surgery, indications, and the length of time between previous surgery and DBE-ERCP were not statistically associated with DBE-ERCP success. The DBE-ERCP success rate increased from 2018 to 2021. CONCLUSIONS: DBE-ERCP is a successful procedure in challenging patients with SAA. The improvement in results over time indicates the necessity of adequate training and of centralizing patients in referral centers.

Flavonoids have been inversely associated to colorectal cancer (CRC) and are plausible intermediaries for the relation among gut microbiome, intestinal permeability and CRC. We analyzed the relation of flavonoid intake with CRC and blood bacterial DNA. We conducted a case-control study in Italy involving 100 incident CRC cases and 200 controls. A valid and reproducible food-frequency questionnaire was used to assess dietary habits and to estimate six flavonoid subclass intakes. We applied qPCR and 16S rRNA gene profiling to assess blood bacterial DNA. We used multiple logistic regression to derive odds ratios (ORs) of CRC and Mann-Whitney and chi--square tests to evaluate abundance and prevalence of operational taxonomic units (OTUs) according to flavonoid intakes. Inverse associations with CRC were found for anthocyanidins (OR for the highest versus the lowest tertile = 0.24, 95% confidence interval, CI = 0.11-0.52) and flavanones (OR = 0.18, 95% CI = 0.08-0.42). We found different abundance and prevalence according to anthocyanidin and flavanone intake for OTUs referring to Oligoflexales order, Diplorickettsiaceae family, Staphylococcus, Brevundimonas, Pelomonas and Escherischia-Shigella genera, and Flavobacterium and Legionella species. The study provides evidence to a protective effect of dietary anthocyanidins and flavanones on CRC and suggests an influence of flavonoids on blood bacterial DNA, possibly through intestinal permeability changes.

A 28-year-old woman, with a history of liver transplantation with Roux-en-Y hepaticjejunostomy, was admitted for melena and severe anemia. Bidirectional endoscopy was normal. Capsule endoscopy demonstrated fresh blood in the efferent limb downstream of the jejuno-jejunostomy. Anterograde double-balloon enteroscopy (DBE) showed an adherent clot with a visible vessel oozing next to the hepaticojejunostomy. Bleeding was treated firstly with argon plasma coagulation and endoclips and further treated with dual emission laser, achieving complete hemostasis. At the 3 months follow-up, hemoglobin was stable without evidence of re-bleeding.
RESUMEN
BACKGROUND: Chicago classification version 4.0 (CCv4.0) introduced stringent diagnostic criteria for oesophagogastric junction outflow obstruction (EGJOO), in order to increase the clinical relevance of the diagnosis, although this has not yet been demonstrated. AIMS: To determine the prevalence of EGJOO using CCv4.0 criteria in patients with CCv3.0-based EGJOO, and to assess if provocative manoeuvres can predict a conclusive CCv4.0 diagnosis of EGJOO. METHODS: Clinical presentation, high resolution manometry (HRM) with rapid drink challenge (RDC), and timed barium oesophagogram (TBE) data were extracted for patients diagnosed with EGJOO as per CCv3.0 between 2018 and 2020. Patients were then re-classified according to CCv4.0 criteria, using clinically relevant symptoms (dysphagia and/or chest pain), and abnormal barium emptying at 5 min on TBE. Receiver operating characteristic (ROC) analyses identified HRM predictors of EGJOO. RESULTS: Of 2010 HRM studies, 144 (7.2%) fulfilled CCv3.0 criteria for EGJOO (median age 61 years, 56.9% female). Upon applying CCv4.0 criteria, EGJOO prevalence decreased to 1.2%. On ROC analysis, integrated relaxation pressure during RDC (RDC-IRP) was a significant predictor of a conclusive EGJOO diagnosis by CCv4.0 criteria (area under the curve: 96.1%). The optimal RDC-IRP threshold of 16.7 mm Hg had 87% sensitivity, 97.1% specificity, 95.7% negative predictive value and 91.3% positive predictive value for a conclusive EGJOO diagnosis; lower thresholds (10 mmHg, 12 mmHg) had better sensitivity but lower specificity. CONCLUSION: CCv4.0 criteria reduced the prevalence of EGJOO by 80%, thereby refining the diagnosis and identifying clinically relevant outflow obstruction. Elevated RDC-IRP can predict conclusive EGJOO per CCv4.0.

The clinical diagnosis of gastro-esophageal reflux disease (GERD) is based on the presence of typical esophageal troublesome symptoms. In clinical practice, heartburn relief following a proton pump inhibitor (PPI) trial or endoscopy can confirm a diagnosis of GERD. In cases of diagnostic uncertainty or before anti-reflux interventions, combined impedance-pH monitoring (MII-pH) provides a comprehensive assessment of both physical and chemical properties of the refluxate, allowing to achieve a conclusive diagnosis of GERD. Recently, the Lyon Consensus proposed the use of mean nocturnal baseline impedance (MNBI) and post-reflux swallow-induced peristaltic wave index (PSPW-I) as novel MII-pH metrics to support the diagnosis of GERD. The calculation of MNBI and PSPW-I currently needs to be performed manually, but artificial intelligence systems for the automated analysis of MII-pH tracings are being developed. Several studies demonstrated the increased diagnostic yield MNBI and PSPW-I for the categorization of patients with GERD at both on- and off-PPI MII-pH monitoring. Accordingly, we performed a narrative review on the clinical use and diagnostic yield of MNBI and PSPW-I when the diagnosis of GERD is uncertain. Based on currently available evidence, we strongly support the evaluation of PSPW-I and MNBI as part of the standard assessment of MII-pH tracings for the evaluation of GERD, especially in patients with endoscopy-negative heartburn.
