RESUMEN
INTRODUCTION: The EndoFLIP (for its acronym in English: endoluminal functional luminal probe) is a system that measures in real time the compliance index of the gastroesophageal junction and secondary esophageal peristalsis, based on the principle of impedance planimetry. Although this technology is relatively new and its diagnostic usefulness is still being evaluated, its use in clinical practice is increasingly recognized, fundamentally in those patients where there is no conclusive manometric diagnosis of esophageal motor pathology, mainly esophagogastric junction outflow obstruction and achalasia. OBJECTIVE: The aim of the present study is to describe the experience with EndoFLIP at the San Ignacio University Hospital in Bogotá, Colombia. MATERIAL AND METHODS: Descriptive observational case series study, which included patients over 18 years of age who had undergone EndoFLIP at the San Ignacio University Hospital from 2021 to 2022, either in-hospital or outpatient, with a clear indication of performance of the study, previously discussed in the multidisciplinary Gastroenterology Board. RESULTS: A total of 27 patients with an average age of 55 years were included in the study, of which 20 were women (74%) and 7 men (26%). The most frequent indication of the study was an inconclusive diagnosis of outflow tract obstruction identified in high-resolution esophageal manometry according to Chicago 4.0 criteria (14 patients), followed by hypercontractile esophagus (4 patients) and ineffective esophageal motility (3 patients). When evaluating the contractile response, it was found that 9 patients with an inconclusive diagnosis of outflow tract obstruction had a normal response, 3 absent and one altered; and in the patients with an inconclusive diagnosis of achalasia, one of them had a borderline contractile response and two had no response. All patients with a previous diagnosis of absent contractility had an equally absent contractile response in EndoFLIP. CONCLUSION: Endoluminal functional luminal imaging is a technique that evaluates biomechanical properties such as distensibility, volume, pressure and even diameters of sphincter regions such as the gastroesophageal junction, pylorus and anus. Its usefulness has been highlighted for several indications, the most important being manometrically inconclusive diagnoses of esophageal motor disorders such as achalasia and outflow tract obstruction, pathologies that have a significant impact on the quality of life of patients and whose diagnosis is essential to be able to provide the best treatment option.

INTRODUCTION: Attempts have been made to identify the genetic factors related to susceptibility to inflammatory bowel disease (IBD), and the current conclusions are in favor of a complex pathology model, without a clear hereditary pattern. OBJECTIVE: To perform phenotypic and genotypic characterization of patients with IBD in Colombian population and to describe its possible association with predisposition. MATERIALS AND METHODS: case series, 16 patients with IBD according to clinical and pathological criteria, onset of gastrointestinal symptoms after 18 years of age. All had pre-test genetic counseling and family trees of at least three generations were made. Also, genotyping, using a multi-gene panel that included genes related to IBD and some autoimmune disorders. Finally, a genomic analysis of variants was performed. RESULTS: 9 women and 7 men, with mean age of diagnosis of IBD of 35 years, and gastrointestinal symptoms appearance of 32 years. 11/16 (68.75%) required biological therapy. 10/16 (62.5%) were refractory to standard therapy. 3/16 (18.75%) had positive family history of IBD. 100% cases presented at least one single nucleotide polymorphism related to IBD risk in more than one gene. The genes most related to ulcerative colitis (UC) were CD48, CD6, and TYK2 for UC, and CD6 and ITGAM for Crohn's disease. The most frequent gene was CD6. It was found presence of up to 5 genes in 3/16 (18.75%), 4 in 3/16 (18.75%), and three in 5/16 (31.25%). CONCLUSION: In IBD there is the presence of genetic variants with associated predisposition, but without confirmed pathogenicity, and whose sum seems to contribute to its pathophysiology.

INTRODUCTION: Treatment of functional disorders of the anorectal unit should focus on the underlying cause. Biofeedback therapy is a functional retraining of the pelvic floor that has proven useful in the treatment of constipation associated with dyssynergia and in the management of fecal incontinence. This study describes the first experiences with this form of biofeedback therapy in Colombia. OBJECTIVE: Describe our experience with biofeedback therapy in the gastrointestinal neurophysiology unit. MATERIALS AND METHODS: This historical cohort included patients with an indication for biofeedback therapy for constipation or fecal incontinence in the gastrointestinal neurophysiology unit during the data collection period. The response to therapy is described by comparing manometricfindings before and after 10 biofeedback sessions. RESULTS: 21 patients were included(71.4% women, the average age was 68, 9 with constipation and 12 with fecal incontinence.Among the patients with constipation there was a significant improvement in 71.4% of those who had rectal hyposensitivity and in 57.1% of those with dyssynergia. Biofeedback therapysignificantly increased the balloon expulsion rate (11.1 vs. 66.7%, p=0.02). In patients with fecal incontinence, there was improvement in 50% of those who had anal hypotonia and in 80% of those who had anal hyposensitivity. CONCLUSIONS: This study demonstrates that biofeedback therapy has a favorable impact on a high number of patients with constipationand fecal incontinence; in our center, the response is similar to that of the world literature.

INTRODUCTION: Currently there is little information in Latin America on the clinical outcome and manometric evolution of patients with Achalasia undergoing peroral endoscopic myotomy (POEM). PRIMARY OUTCOME: Evaluate the manometric and clinical changes in adult patients with achalasia after peroral endoscopic myotomy at a referral center in Bogotá, Colombia. METHODS: Observational, analytical, longitudinal study. Adult patients with achalasia according to the Chicago 4.0 criteria were included. Sociodemographic, clinical and manometric variables were described. To compare the pre- and post-surgical variables, the Student's or Wilcoxon's t test was used for the quantitative variables according to their normality, and McNemar's chi-square for the qualitative variables. RESULTS: 29 patients were included, 55.17% (n=16) women, with a mean age at the time of surgery of 48.2 years (±11.33). The mean post-procedure evaluation time was 1.88±0.81 years. After the procedure, there was a significant decrease in the proportion of patients with weight loss (37.93% vs 21.43% p 0.0063), chest pain (48.28% vs 21.43, p 0.0225) and the median Eckardt score (8 (IQR 8 -9) vs 2(IQR 1-2), p <0.0001). In addition, in fourteen patients with post-surgical manometry, significant differences were found between IRP values (23.05±14.83mmHg vs 7.69±6.06mmHg, p 0.026) and in the mean lower esophageal sphincter tone (9.63±7.2mmHg vs 28.8±18.60mmHg, p 0.0238). CONCLUSION: Peroral endoscopic myotomy has a positive impact on the improvement of symptoms and of some manometric variables (IRP and LES tone) in patients with achalasia.

BACKGROUND: Diagnosing gastroesophageal reflux disease (GERD) can be challenging given varying symptom presentations, and complex multifactorial pathophysiology. The gold standard for GERD diagnosis is esophageal acid exposure time (AET) measured by pH-metry. A variety of additional diagnostic tools are available. The goal of this consensus was to assess the individual merits of GERD diagnostic tools based on current evidence, and provide consensus recommendations following discussion and voting by experts. METHODS: This consensus was developed by 15 experts from nine countries, based on a systematic search of the literature, using GRADE (grading of recommendations, assessment, development and evaluation) methodology to assess the quality and strength of the evidence, and provide recommendations regarding the diagnostic utility of different GERD diagnosis tools, using AET as the reference standard. KEY RESULTS: A proton pump inhibitor (PPI) trial is appropriate for patients with heartburn and no alarm symptoms, but nor for patients with regurgitation, chest pain, or extraesophageal presentations. Severe erosive esophagitis and abnormal reflux monitoring off PPI are clearly indicative of GERD. Esophagram, esophageal biopsies, laryngoscopy, and pharyngeal pH monitoring are not recommended to diagnose GERD. Patients with PPI-refractory symptoms and normal endoscopy require reflux monitoring by pH or pH-impedance to confirm or exclude GERD, and identify treatment failure mechanisms. GERD confounders need to be considered in some patients, pH-impedance can identify supragrastric belching, impedance-manometry can diagnose rumination. CONCLUSIONS: Erosive esophagitis on endoscopy and abnormal pH or pH-impedance monitoring are the most appropriate methods to establish a diagnosis of GERD. Other tools may add useful complementary information.

RESUMEN
The Lyon Consensus provides conclusive criteria for and against the diagnosis of gastro-oesophageal reflux disease (GERD), and adjunctive metrics that consolidate or refute GERD diagnosis when primary criteria are borderline or inconclusive. An international core and working group was assembled to evaluate research since publication of the original Lyon Consensus, and to vote on statements collaboratively developed to update criteria. The Lyon Consensus 2.0 provides a modern definition of actionable GERD, where evidence from oesophageal testing supports revising, escalating or personalising GERD management for the symptomatic patient. Symptoms that have a high versus low likelihood of relationship to reflux episodes are described. Unproven versus proven GERD define diagnostic strategies and testing options. Patients with no prior GERD evidence (unproven GERD) are studied using prolonged wireless pH monitoring or catheter-based pH or pH-monitoring off antisecretory medication, while patients with conclusive GERD evidence (proven GERD) and persisting symptoms are evaluated using pH-impedance monitoring while on optimised antisecretory therapy. The major changes from the original Lyon Consensus criteria include establishment of Los Angeles grade B oesophagitis as conclusive GERD evidence, description of metrics and thresholds to be used with prolonged wireless pH monitoring, and inclusion of parameters useful in diagnosis of refractory GERD when testing is performed on antisecretory therapy in proven GERD. Criteria that have not performed well in the diagnosis of actionable GERD have been retired. Personalisation of investigation and management to each patient's unique presentation will optimise GERD diagnosis and management.

There is little information on the degree of concordance between the results obtained using the Chicago 3.0 (CCv3.0) and Chicago 4.0 (CCv4.0) protocols to interpret high-resolution manometry (HRM) seeking to determine the value provided by the new swallowing maneuvers included in the last protocol. This is a study of diagnostic tests, evaluating concordance by consistency between the results obtained by the CCv3.0 and CCv4.0 protocols, in patients undergoing HRM. Concordance was assessed with the kappa test. Bland-Altman scatter plots, and Lin's correlation-concordance coefficient (CCC) were used to assess the agreement between IRP measured with swallows in the supine and seated position or with solid swallows. One hundred thirty-two patients were included (65% women, age 53 ± 17 years). The most frequent HRM indication was dysphagia (46.1%). Type I was the most common type of gastroesophageal junction. The most frequent CCv4.0 diagnoses were normal esophageal motility (68.9%), achalasia (15.5%), and ineffective esophageal motility (IEM; 5.3%). The agreement between the results was substantial (Kappa 0.77 ± 0.05), with a total agreement of 87.9%. Diagnostic reclassification occurred in 12.1%, from IEM in CCv3.0 to normal esophageal motility in CCv4.0. Similarly, there was a high level of agreement between the IRP measured in the supine compared to the seated position (CCC0.92) and with solid swallows (CCC0.96). In conclusion, the CCv4.0 protocol presents a high concordance compared to CCv3.0. In the majority of manometric diagnoses there is no reclassification of patients with provocation tests. However, the more restrictive criteria of CCv4.0 achieve a better reclassification of patients with IEM.

Sjögren's syndrome is a systemic autoimmune disease characterized by dry eyes and mouth due to the involvement of exocrine glands. However, it can manifest with GI symptoms that cover a broad spectrum from esophageal and intestinal dysmotility, achalasia, hypochlorhydria, and chronic atrophic gastritis to pancreatic enzyme deficiency, biliary dysfunction, and liver cirrhosis, which varies in its clinical manifestations and is often associated with erroneous approaches. This article reviews the GI manifestations of Sjögren's syndrome. It presents the case of a woman in her eighth decade of life with this syndrome. She showed asymptomatic hepatobiliary disease, documented abnormalities in liver profile tests, and a subsequent diagnosis of primary sclerosing cholangitis, for which she received initial treatment with ursodeoxycholic acid. During her condition, the patient has had three episodes of cholangitis, requiring endoscopic retrograde cholangiopancreatography with no findings of stones, with scant biliary sludge and discharge of purulent bile precipitated by her underlying liver disease. The association between Sjögren's syndrome and primary sclerosing cholangitis is rare and calls for special consideration.
El síndrome de Sjögren es una enfermedad autoinmune sistémica que se caracteriza por la sequedad ocular y bucal debido a la afección de glándulas exocrinas; sin embargo, puede manifestarse con síntomas gastrointestinales que abarcan un espectro amplio desde la dismotilidad esofágica e intestinal, acalasia, hipoclorhidria y gastritis crónica atrófica hasta enzimodeficiencia pancreática, disfunción biliar y cirrosis hepática, que tiene variación en sus manifestaciones clínicas y se asocia con abordajes erróneos en muchas ocasiones. En este artículo se hace una revisión acerca de las manifestaciones gastrointestinales de síndrome de Sjögren y se presenta el caso de una mujer en la octava década de la vida con este síndrome, que cursa con enfermedad hepatobiliar asintomática, documentación de alteración en pruebas de perfil hepático y diagnóstico ulterior de colangitis esclerosante primaria, por lo que recibió un tratamiento inicial con ácido ursodesoxicólico. Durante el curso de su enfermedad ha presentado 3 episodios de colangitis, con requerimiento de colangiopancreatografía retrógrada endoscópica sin hallazgos de cálculos, con escaso barro biliar y salida de bilis purulenta, precipitada por su enfermedad hepática de base. La asociación entre el síndrome de Sjögren y la colangitis esclerosante primaria es infrecuente y justifica una consideración especial.
RESUMEN
Introduction: Limited information is available regarding the clinical and manometric characteristics of different subtypes of achalasia. This study aims to describe these characteristics in patients treated at a prominent hospital in Colombia. Methods: This descriptive observational study included patients diagnosed with achalasia using high-resolution esophageal manometry at Hospital Universitario San Ignacio in Bogotá, Colombia, between 2016 and 2020. We documented the clinical manifestations, manometric findings, treatment approaches, and response to treatment based on the subtype of achalasia. Results: A total of 87 patients were enrolled, with a median age of 51 years, and 56.4% of them were female. The majority had type II achalasia (78.1%), followed by type I (16%) and type III (5.7%). All patients presented with dysphagia, 40.2% experienced chest pain, and 27.6% had gastroesophageal reflux. The clinical parameters, including integrated relaxation pressure value (IRP; median: 24 mmHg, interquartile range [IQR]: 19-33), upper esophageal sphincter pressure (UES; median: 63 mmHg, IQR: 46-98), and lower esophageal sphincter pressure (LES; median: 34 mm Hg, IQR: 26-45), were similar across the different subtypes. Esophageal clearance was incomplete in all patients. Among the 35 patients who received intervention, Heller's myotomy was the most commonly employed procedure (68.5%), followed by esophageal dilation (28.6%). All patients experienced symptomatic improvement, with a median pre-treatment Eckardt score of 5 (IQR: 5-6) and a post-treatment score of 1 (IQR: 1-2). Conclusions: Type II achalasia is the most prevalent subtype. The clinical and manometric findings, as well as treatment response, exhibit similarities among the different subtypes of achalasia. In Colombia, the outcomes of this condition align with those reported in other parts of the world.
Introducción: existe información limitada sobre las características clínicas y manométricas de los diferentes subtipos de acalasia. Este estudio describe dichas características en pacientes manejados en un hospital de referencia en Colombia. Método: estudio descriptivo observacional que incluye a pacientes con diagnóstico de acalasia por manometría esofágica de alta resolución manejados en el Hospital Universitario San Ignacio de Bogotá, Colombia, entre 2016 y 2020. Se describen las manifestaciones clínicas, hallazgos manométricos, tratamiento utilizado y respuesta al mismo según el subtipo de acalasia. Resultados: se incluyeron a 87 pacientes (mediana de edad: 51 años, 56,4% mujeres). La mayoría de tipo II (78,1%), seguido por tipo I (16%) y tipo III (5,7%). Todos presentaron disfagia, 40,2% dolor torácico y 27,6% reflujo gastroesofágico. La clínica y los valores del integral de presión de relajación (IRP; mediana: 24 mm Hg, rango intercuartílico [RIC]: 19-33), presión del esfínter esofágico superior (EES; mediana: 63 mm Hg, RIC: 46-98) y presión del esfínter esofágico inferior (EEI; mediana: 34 mm Hg, RIC: 26-45) fueron similares en los diferentes subtipos. El aclaramiento esofágico fue incompleto en todos los pacientes. Entre 35 pacientes que recibieron manejo intervencionista, la miotomía de Heller fue la intervención más utilizada (68,5%), seguido por la dilatación esofágica (28,6%). La totalidad de estos pacientes presentó una mejoría sintomática con la mediana de Eckardt pretratamiento de 5 (RIC: 5-6) y postratamiento de 1 (RIC: 1-2). Conclusiones: la acalasia tipo II es la más común. La clínica y los hallazgos manométricos y respuesta a tratamiento son similares entre los subtipos de acalasia. En Colombia, esta entidad se comporta de forma similar a lo reportado en otras partes del mundo.
RESUMEN
BACKGROUND AND AIMS: The Rome Foundation Global Epidemiology Study (RFGES) assessed the prevalence, burden, and associated factors of Disorders of Gut-Brain Interaction (DGBI) in 33 countries around the world. Achieving worldwide sampling necessitated use of two different surveying methods: In-person household interviews (9 countries) and Internet surveys (26 countries). Two countries, China and Turkey, were surveyed with both methods. This paper examines the differences in the survey results with the two methods, as well as likely reasons for those differences. METHODS: The two RFGES survey methods are described in detail, and differences in DGBI findings summarized for household versus Internet surveys globally, and in more detail for China and Turkey. Logistic regression analysis was used to elucidate factors contributing to these differences. RESULTS: Overall, DGBI were only half as prevalent when assessed with household vs Internet surveys. Similar patterns of methodology-related DGBI differences were seen within both China and Turkey, but prevalence differences between the survey methods were dramatically larger in Turkey. No clear reasons for outcome differences by survey method were identified, although greater relative reduction in bowel and anorectal versus upper gastrointestinal disorders when household versus Internet surveying was used suggests an inhibiting influence of social sensitivity. CONCLUSIONS: The findings strongly indicate that besides affecting data quality, manpower needs and data collection time and costs, the choice of survey method is a substantial determinant of symptom reporting and DGBI prevalence outcomes. This has important implications for future DGBI research and epidemiological research more broadly.

BACKGROUND: In Latin America, there are scarce data on the epidemiology of DGBI. The Rome Foundation Global Epidemiology Study (RFGES) Internet survey included 26 countries, four from Latin America: Argentina, Brazil, Colombia, and Mexico, with a 40.3% prevalence of Rome IV DGBI. We aimed at comparing the prevalence of DGBI and associated factors among these countries. METHODS: The frequency of DGBI by anatomical region, specific diagnoses, sex, age, diet, healthcare access, anxiety, depression, and HRQOL, were analyzed and compared. RESULTS: Subjects included Argentina n = 2057, Brazil = 2004, Colombia = 2007, and Mexico = 2001. The most common DGBI were bowel (35.5%), gastroduodenal (11.9%), and anorectal (10.0%). Argentina had the highest prevalence of functional diarrhea (p = 0.006) and IBS-D; Brazil, esophageal, gastroduodenal disorders, and functional dyspepsia; Mexico functional heartburn (all <0.001). Overall, DGBI were more common in women vs. men and decreased with age. Bowel disorders were more common in the 18-39 (46%) vs. 40-64-year (39%) groups. Diet was also different between those with DGBI vs. those without with subtle differences between countries. Subjects endorsing criteria for esophageal, gastroduodenal, and anorectal disorders from Mexico, more commonly consulted physicians for bowel symptoms vs. those from Argentina, Brazil, and Colombia. General practitioners were the most frequently consulted, by Mexicans (50.42%) and Colombians (40.80%), followed by gastroenterologists. Anxiety and depression were more common in DGBI individuals in Argentina and Brazil vs. Mexico and Colombia, and they had lower HRQOL. CONCLUSIONS: The prevalence of upper and lower DGBI, as well as the burden of illness, psychological impact and HRQOL, differ between these Latin American countries.

Inflammatory bowel disease (IBD) comprises a spectrum of chronic immune-mediated diseases that affect the gastrointestinal tract. Onset typically occurs in early adulthood. The incidence of this disease has increased worldwide. Its prevalence has increased in Colombia and occurs predominantly in women. Considering that this disease is not curable, the main objective of management is to achieve remission. Many women are affected by IBD during different stages of their lives, including their reproductive life, pregnancy, and menopause. Because of this, the way the disease is managed in women of reproductive age can affect the course of IBD. Treatment and health maintenance strategies are very relevant; for patients with a desire to conceive, remission of the disease is very important at the time of conception and throughout the pregnancy to ensure adequate outcomes for both mother and fetus. Also, remission is necessary at least 3 months prior to conception. It is well known that active disease during conception and pregnancy is associated with adverse outcomes. In addition, active perianal disease is an indication of cesarean delivery, resulting in an increased risk of intestinal surgery and post-operative complications.
RESUMEN
Abstract Autoimmune gastritis is an underdiagnosed disease in the pediatric population due to the absence of specific signs and symptoms and late clinical manifestations. Iron deficiency anemia has recently been identified as an early hematological manifestation, allowing an early diagnostic approach. We present the case of a Colombian teenager, with no history of autoimmunity, with refractory iron deficiency. He underwent extension studies; biopsies and serology compatible with autoimmune gastritis were documented, requiring parenteral iron in its evolution. This pathology is underdiagnosed in our context since early diagnosis requires a high index of suspicion to prevent associated complications.
Resumen La gastritis autoinmune es una enfermedad subdiagnosticada en la población pediátrica. Lo anterior se debe a la ausencia de signos y síntomas específicos y manifestaciones clínicas tardías. Recientemente se ha identificado la anemia ferropénica como una manifestación hematológica precoz, lo que permite un enfoque diagnóstico temprano. Se presenta el caso de un adolescente colombiano, sin antecedentes de autoinmunidad, con ferropenia refractaria, en el que se realizaron estudios de extensión y se documentaron biopsias y serología compatible con gastritis autoinmune, con requerimiento de hierro parenteral en su evolución. Esta patología es subdiagnosticada en nuestro medio, ya que el diagnóstico temprano requiere un alto índice de sospecha, lo que permite la prevención de las complicaciones asociadas.

INTRODUCTION: Grading dysphagia is crucial for clinical management of patients. The Eckardt score (ES) is the most commonly used for this purpose. We aimed to compare the ES with the recently developed Brief Esophageal Dysphagia Questionnaire (BEDQ) in terms of their correlation and discriminative capacity for clinical and manometric findings and evaluate the effect of gastroesophageal reflux symptoms on both. METHODS: Symptomatic patients referred for high-resolution manometry (HRM) were prospectively recruited from seven centers in Spain and Latin America. Clinical data and several scores (ES, BEDQ, GERDQ) were collected and contrasted to HRM findings. Standard statistical analysis was performed. KEY RESULTS: 426 patients were recruited, 31.2% and 41.5% being referred exclusively for dysphagia and GERD symptoms, respectively. Both BEDQ and ES were independently associated with achalasia. Only BEDQ was independently associated with being referred for dysphagia and with relevant HRM findings. ROC curve analysis for achalasia diagnosis showed AUC of 0.809 for BEDQ and 0.765 for ES, with the main difference being higher BEDQ sensitivity (80.0% vs 70.8% for ES). GERDQ independently predicted ES but not BEDQ. In the absence of dysphagia (BEDQ = 0), GERD symptoms significantly determine ES. CONCLUSIONS AND INFERENCES: Our study suggests both the BEDQ and ES can complementarily describe symptomatic burden in achalasia. BEDQ has several advantages over the ES in the dysphagia evaluation, basically due to its higher sensitivity for manometric diagnosis and independence of GERD symptoms. ES should be used as an achalasia-specific metric, while BEDQ is a better symptom-generic evaluating tool.

BACKGROUND: High-resolution impedance manometry (HRIM) evaluates esophageal peristalsis and bolus transit. We used esophageal impedance integral (EII), the ratio between bolus presence before and after an expected peristaltic wave, to evaluate predictors of bolus transit. METHODS: From HRIM studies performed on 61 healthy volunteers (median age 27 years, 48%F), standard metrics were extracted from each of 10 supine water swallows: distal contractile integral (DCI, mmHg cm s), integrated relaxation pressure (IRP, mmHg), and breaks in peristaltic integrity (cm, using 20 mmHg isobaric contour). Pressure and impedance coordinates for each swallow were exported into a dedicated, python-based program for EII calculation (EII ratio ≥ 0.3 = abnormal bolus clearance). Univariate and multivariate analyses were performed to assess predictors of abnormal bolus clearance. KEY RESULTS: Of 591 swallows, 80.9% were intact, 10.5% were weak, and 8.6% failed. Visual analysis overestimated abnormal bolus clearance compared to EII ratio (p ≤ 0.01). Bolus clearance was complete (median EII ratio 0.0, IQR 0-0.12) in 82.0% of intact swallows in contrast to 53.3% of weak swallows (EII ratio 0.29, IQR 0.0-0.57), and 19.6% of failed swallows (EII ratio 0.5, IQR 0.34-0.73, p < 0.001). EII correlated best with break length (ρ = 0.52, p < 0.001), compared to IRP (ρ: -0.17) or DCI (ρ: -0.42). On ROC analysis, breaks predicted abnormal bolus transit better than DCI or IRP (AUC 0.79 vs. 0.25 vs. 0.44, p ≤ 0.03 for each). On logistic regression, breaks remained independently predictive of abnormal bolus transit (p < 0.001). CONCLUSIONS & INFERENCES: Breaks in peristaltic integrity predict abnormal bolus clearance better than DCI or IRP in healthy asymptomatic subjects.

OBJECTIVE: High-resolution manometry (HRM) is the current standard for characterization of esophageal body and esophagogastric junction (EGJ) function. We aimed to examine the prevalence of abnormal esophageal motor patterns in health, and to determine optimal thresholds for software metrics across HRM systems. DESIGN: Manometry studies from asymptomatic adults were solicited from motility centers worldwide, and were manually analyzed using integrated relaxation pressure (IRP), distal latency (DL), and distal contractile integral (DCI) in standardized fashion. Normative thresholds were assessed using fifth and/or 95th percentile values. Chicago Classification v3.0 criteria were applied to determine motor patterns across HRM systems, study positions (upright vs supine), ages, and genders. RESULTS: Of 469 unique HRM studies (median age 28.0, range 18-79 years). 74.6% had a normal HRM pattern; none had achalasia. Ineffective esophageal motility (IEM) was the most frequent motor pattern identified (15.1% overall), followed by EGJ outflow obstruction (5.3%). Proportions with IEM were lower using stringent criteria (10.0%), especially in supine studies (7.1%-8.5%). Other motor patterns were rare (0.2%-4.1% overall) and did not vary by age or gender. DL thresholds were close to current norms across HRM systems, while IRP thresholds varied by HRM system and study position. Both fifth and 95th percentile DCI values were lower than current thresholds, both in upright and supine positions. CONCLUSIONS: Motor abnormalities are infrequent in healthy individuals and consist mainly of IEM, proportions of which are lower when using stringent criteria in the supine position. Thresholds for HRM metrics vary by HRM system and study position.
