High-Resolution Manometry Contributions to the Physiology of Phonation

High-resolution manometry (HRM) is a motility diagnostic system that measures intraluminal pressure of the gastrointestinal tract using a series of closely spaced pressure sensors. The topographic plot generated by HRM software makes it possible to visualize phonation pressures at the pharynx, UES, and body of the esophagus in real time, indicating pressure intensity by color, which permits easy data interpretation. It has been largely used for swallowing study and dysphagia diagnosis. Due to the proximity of the pharyngoesophageal and laryngeal structures, this technology instigated voice researchers. Despite the few studies published so far, high-resolution manometry has yet proven to be an extremely useful tool in obtaining entire pharyngoesophageal segment pressure measurements during phonation. It also allows natural voice production not interfering with the mouth area. HRM data already brought light to subglottic pressure, vertical laryngeal excursion, cricopharyngeal muscle activation, air flow, muscle tension associated with vocalization and pressure variations associated with different phonatory stimuli.

La manometría de alta resolución (HRM, por sus siglas en inglés) es un sistema de diagnóstico de motilidad que mide la presión intraluminal del tracto gastrointestinal mediante una serie de sensores de presión dispuestos de manera cercana. El gráfico topográfico generado por el software de HRM permite visualizar las presiones de fonación en la faringe, el EEI y el cuerpo del esófago en tiempo real, indicando la intensidad de la presión mediante colores que facilitan la interpretación de los datos. Ha sido ampliamente utilizado para el estudio de la deglución y el diagnóstico de la disfagia. Debido a la proximidad de las estructuras faringoesofágicas y laríngeas, esta tecnología ha despertado el interés de los investigadores en voz. A pesar de los pocos estudios publicados hasta ahora, la manometría de alta resolución ha demostrado ser una herramienta extremadamente útil para obtener mediciones de presión de todo el segmento faringoesofágico durante la fonación. Además, permite la producción natural de la voz sin interferir en el área de la boca. Los datos de HRM ya han arrojado luz sobre la presión subglótica, la excursión laríngea vertical, la activación del músculo cricofaríngeo, el flujo de aire, la tensión muscular asociada con la vocalización y las variaciones de presión asociadas con diferentes estímulos fonatorios.

Dyssynergic Defecation Concerning Proctalgia Fugax: An Observational Study

Introduction: There is no clarity about manometric findings in patients with proctalgia fugax; evidence shows different results. This study aims to evaluate dyssynergic defecation through anorectal manometry in Colombian patients in two gastroenterology centers in Bogotá, Colombia. Materials and methods: A cross-sectional descriptive observational study in adult patients with proctalgia fugax undergoing anorectal manometry and treated in two gastroenterology centers in Bogotá between 2018 and 2020. Results: 316 patients were included, predominantly women (65%), with a median age of 45.2 (range: 18-78; standard deviation [SD]: 28.3). Four percent of patients had hypertonicity, 50% were normotonic, and 46% were hypotonic. Regarding manometric parameters, 50% had normal pressure, and 46% had anal sphincter hypotonia; 76% had a normal voluntary contraction test. Dyssynergic defecation was documented in 5% of patients, and the most frequent was type I, followed by type III. A rectoanal inhibitory reflex was identified in all patients, 42% with altered sensory threshold and 70% with abnormal balloon expulsion. There was an agreement between the results of the anorectal manometry and the subjective report of the digital rectal exam by the head nurse who performed the procedure. Conclusions: The data obtained in the present study suggest that proctalgia is not related to the elevated and sustained basal contracture of the sphincter but neither to the alteration in voluntary contraction since most patients have typical values.

Introducción: Actualmente, no hay claridad acerca de los hallazgos manométricos en pacientes con proctalgia fugaz, y la evidencia muestra diferentes resultados. Se plantea como objetivo en el presente estudio evaluar la presencia de disinergia defecatoria con manometría anorrectal en pacientes colombianos en dos centros de gastroenterología en Bogotá, Colombia. Metodología: Estudio observacional descriptivo de corte transversal en pacientes adultos sometidos a manometría anorrectal con proctalgia fugaz y atendidos en dos centros de gastroenterología de la ciudad de Bogotá entre el 2018 y el 2020. Resultados: Se incluyó a 316 pacientes, predominantemente mujeres (65%), con mediana de edad 45,2 (rango: 18-78; desviación estándar [DE]: 28,3). El 4% de los pacientes presentaban hipertonicidad, el 50% eran normotónicos y el 46%, hipotónicos. En cuanto a parámetros manométricos, el 50% tenía presión normal y el 46%, hipotonía de esfínter anal. El 76% tuvo una prueba de contracción voluntaria normal. En 5% pacientes se documentó disinergia defecatoria, y la más frecuente fue el tipo I, seguido del tipo III. En todos los pacientes se identificó reflejo recto anal inhibitorio, 42% con alteración en umbral sensitivo y 70% con expulsión de balón anormal, y hubo concordancia entre los resultados de la manometría anorrectal y el reporte subjetivo del tacto rectal de la jefe de enfermería que realizó el procedimiento. Conclusiones: Los datos obtenidos en el presente estudio sugieren que la proctalgia no está relacionada con la contractura basal elevada y sostenida del esfínter, pero tampoco con la alteración en la contracción voluntaria, ya que la mayoría de los pacientes presentan valores normales.

Esclerodermia y alteraciones esofágicas documentadas por manometría / Scleroderma and Esophageal Alterations Documented by Manometry

Introducción: Las manifestaciones gastrointestinales y en especial la disfunción esofágica son frecuentes en pacientes con diagnóstico de esclerosis sistémica. Objetivos: Determinar los hallazgos manométricos en el esófago de pacientes con esclerosis sistémica. Métodos: Se realizó un estudio descriptivo de corte transversal, en 86 pacientes con diagnóstico de esclerosis sistémica que fueron atendidos en el Servicio de Reumatología del Hospital Hermanos Ameijeiras, en el período comprendido de enero de 2020 a diciembre de 2021. Resultados: La edad media fue de 49,5 ± 15,3 años, (94,3 por ciento) en el sexo femenino. El (90,7 por ciento) tenía trastornos de la motilidad esofágica, principalmente los trastornos mayores (58,1por ciento) y el esfínter esofágico corto (62,8 por ciento). La presencia de síntomas como la regurgitación, la pirosis y la disfagia se relacionaron de forma significativa en la mayoría de los parámetros manométricos. De igual forma, el tiempo de evolución de la enfermedad (10,1 ± 9,1 frente a 5,9 ± 5,9 años), el fenómeno de Raynaud (93,9 por ciento frente a 25,0 por ciento) y la esclerosis sistémica difusa (96,2 por ciento frente a 82,4 por ciento) fueron significativamente mayores en pacientes con trastornos de la motilidad esofágica. La edad y el sexo no mostraron una asociación significativa con las alteraciones manométricas. Conclusiones: Se concluye que los pacientes con esclerosis sistémica difusa, fenómeno de Raynaud, a partir de la presencia de los síntomas y de la evolución de la enfermedad tienen una elevada probabilidad de padecer trastornos de la motilidad esofágica(AU)

Introduction: Gastrointestinal manifestations, and especially esophageal dysfunction, are common in patients diagnosed with systemic sclerosis. Objectives: To determine the manometric findings in the esophagus of patients with systemic sclerosis. Methods: A descriptive cross-sectional study was carried out on 86 patients with a diagnosis of systemic sclerosis who were treated in the Rheumatology Service of Hermanos Ameijeiras Hospital from January 2020 to December 2021. Results: The mean age was 49.5 ± 15.3 years, (94.3percent) in females. 90.7percent had esophageal motility disorders, mainly major disorders (58.1percent) and 62.8percent had short esophageal sphincter. The presence of symptoms such as regurgitation, heartburn and dysphagia were significantly related to most manometric parameters. Similarly, the duration of the disease (10.1 ± 9.1 versus 5.9 ± 5.9 years), Raynaud's phenomenon (93.9percent versus 25.0percent) and sclerosis diffuse systemic (96.2percent vs. 82.4percent) were significantly higher in patients with esophageal motility disorders. Age and sex did not show significant association with manometric alterations. Conclusions: It is concluded that patients with diffuse systemic sclerosis, Raynaud's phenomenon, based on the presence of symptoms, and the evolution of the disease, have high probability of suffering from esophageal motility disorders(AU)

Introducción. La acalasia es un trastorno motor del esófago caracterizado por la ausencia de peristalsis y la alteración en la relajación del esfínter esofágico inferior. La cardiomiotomía laparoscópica de Heller más funduplicatura parcial es el tratamiento estándar. La mejoría sintomática ha sido bien documentada, pero no hay suficiente información objetiva respecto a los cambios fisiológicos y radiográficos luego del procedimiento. Métodos. Estudio de cohorte bidireccional de pacientes llevados a cardiomiotomía laparoscópica de Heller, entre los años 2018 y 2021, en el Hospital Universitario San Vicente Fundación de Medellín, Colombia. Se describen variables demográficas y clínicas. Se realizaron puntaje sintomático de Eckardt, manometría esofágica y radiografía de esófago en el pre y postoperatorio. Se hizo comparación de síntomas, presión basal del esfínter esofágico inferior, presión de relajación integrada y diámetro del esófago antes y después de la intervención. Resultados. Se incluyeron 24 pacientes. El 63 % fueron mujeres y la edad promedio fue de 44 años. Los valores promedio preoperatorios vs postoperatorios fueron: puntaje de Eckardt 10,6 vs 1,4 puntos (p<0,001), presión basal de 41,4 vs 18,1 mmHg (p=0,004) y presión de relajación integrada de 28,6 vs 12,5 mmHg (p=0,001). El diámetro del esófago no presentó cambios. No hubo correlación de síntomas con los cambios de presión del esfínter esofágico inferior. El tiempo de seguimiento fue de 20 meses. Conclusiones. La cardiomiotomía de Heller es un procedimiento altamente efectivo para el tratamiento definitivo de la acalasia, logrando una mejoría subjetiva y objetiva basada en síntomas y en parámetros de manometría, respectivamente

Introduction. Achalasia is a motor disorder of the esophagus characterized by the absence of peristalsis and impaired relaxation of the lower esophageal sphincter. Laparoscopic Heller ́s cardiomyotomy plus partial fundoplication is the standard treatment. Symptomatic improvement has been well documented, but there is insufficient objective information regarding physiologic and radiographic changes after the procedure. Methods. Bidirectional cohort study of patients underwent laparoscopic Heller ́s cardiomyotomy between 2018 and 2021 at the San Vicente Fundación University Hospital in Medellín, Colombia. Demographic and clinical variables are described. Eckardt symptom score, esophageal manometry, and esophageal radiography were performed pre and postoperatively. A comparison of symptoms, baseline lower esophageal sphincter pressure, integrated relaxation pressure, and esophageal diameter before and after intervention were performed.Results. 24 patients were included. 63% were women and the average age was 44 years. The preoperative vs. postoperative mean values were: Eckardt score 10.6 vs. 1.4 points (p<0.001), basal pressure of 41.4 vs. 18.1 mmHg (p=0.004) and integrated relaxation pressure of 28.6 vs. 12.5 mmHg (p=0.001). The diameter of the esophagus did not present changes. There was no correlation of symptoms with lower esophageal sphincter pressure changes. The follow-up time was 20 months. Conclusions. Heller cardiomyotomy is a highly effective procedure for the definitive treatment of achalasia, achieving subjective and objective improvements, based on symptoms and manometry parameters, respectively

Characterization of Achalasia Subtypes Based on High-Resolution Manometry in Patients at a Reference Hospital in Colombia

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.

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.

Diferencias en la duración del reflejo rectoanal inhibitorio en pacientes con constipación funcional refractaria y mielomeningocele / Differences in rectoanal inhibitory reflex duration between patients with refractory functional constipation and myelomeningocele

Introducción. Habitualmente, durante la manometría anorrectal, en lo correspondiente al reflejo rectoanal inhibitorio (RRAI) solo se pesquisa su presencia o ausencia. Estudios han reportado que su análisis detallado puede brindar datos de interés. Nuestra hipótesis es que la medición del RRAI puede dar información para reconocer causas orgánicas (médula anclada, lipoma, etc.) en pacientes en los que previamente se consideró como de causa funcional. Objetivos. Comparar la duración del reflejo rectoanal inhibitorio en la manometría anorrectal de pacientes con constipación funcional refractaria (CFR) y mielomeningocele (MMC). Población y métodos. Estudio observacional, transversal, analítico (2004-2019). Pacientes constipados crónicos con incontinencia fecal funcional y orgánica (mielomeningocele). Se les realizó manometría anorrectal con sistema de perfusión de agua y se midió la duración del RRAI con diferentes volúmenes (20, 40 y 60 cc). Grupo 1 (G1): 81 CFR. Grupo 2 (G2): 54 MMC. Se excluyeron pacientes con retraso madurativo, esfínter anal complaciente, agenesia sacra y aquellos no colaboradores. Resultados. Se incluyeron 135 sujetos (62 varones). La mediana de edad fue G1:9,57 años; G2: 9,63 años. Duración promedio G1 vs. G2 con 20 cc: 8,89 vs. 15,21 segundos; con 40 cc: 11.41 vs. 21,12 segundos; con 60 cc: 14,15 vs. 26,02 segundos. La diferencia de duración del RRAI entre ambos grupos con diferentes volúmenes fue estadísticamente significativa (p = 0,0001). Conclusión. La duración del RRAI aumenta a mayor volumen de insuflación del balón en ambas poblaciones. Pacientes con MMC tuvieron mayor duración del RRAI que aquellos con CFR. En los pacientes con RRAI prolongado, debe descartarse lesión medular.

Introduction. Usually, during anorectal manometry, only the presence or absence of rectoanal inhibitory reflex (RAIR) is investigated. Studies have reported that a detailed analysis may provide data of interest. Our hypothesis is that RAIR measurement may provide information to detect organic causes (tethered cord, lipoma, etc.) in patients in whom a functional cause had been previously considered. Objectives. To compare RAIR duration in anorectal manometry between patients with refractory functional constipation (RFC) and myelomeningocele (MMC). Population and methods. Observational, analytical, cross-sectional study (2004­2019). Patients with chronic constipation and functional and organic fecal incontinence (myelomeningocele). The anorectal manometry was performed with a water-perfused system, and the duration of RAIR was measured with different volumes (20, 40, and 60 cc). Group 1 (G1): 81 RFC. Group 2 (G2): 54 MMC. Patients with developmental delay, compliant anal sphincter, sacral agenesis and non-cooperative patients were excluded. Results. A total of 135 individuals were included (62 were male). Their median age was 9.57 years in G1 and 9.63 years in G2. Average duration in G1 versus G2 with 20 cc: 8.89 versus 15.21 seconds; 40 cc: 11.41 versus 21.12 seconds; 60 cc: 14.15 versus 26.02 seconds. The difference in RAIR duration with the varying volumes was statistically significant (p = 0.0001). Conclusion. RAIR duration was longer with increasing balloon inflation volumes in both populations. RAIR duration was longer in patients with MMC than in those with RFC. Spinal injury should be ruled out in patients with prolonged RAIR.

Achalasia is a multimodal esophageal disorder, with predominantly gastrointestinal manifestations, so its timely diagnosis and therapeutic approach is essential to improve the quality of life of patients.

Laparoscopic antireflux surgery: were old questions answered? partial or total fundoplication? / Cirurgia laparoscópica antirrefluxo: perguntas antigas foram respondidas? fundoplicatura parcial ou total?

ABSTRACT Laparoscopic total fundoplication is currently considered the gold standard for the surgical treatment of gastroesophageal reflux disease. Short-term outcomes after laparoscopic total fundoplication are excellent, with fast recovery and minimal perioperative morbidity. The symptom relief and reflux control are achieved in about 80 to 90% of patients 10 years after surgery. However, a small but clinically relevant incidence of postoperative dysphagia and gas-related symptoms is reported. Debate still exists about the best antireflux operation; during the last three decades, the surgical outcome of laparoscopic partial fundoplication (anterior or posterior) were compared to those achieved after a laparoscopic total fundoplication. The laparoscopic partial fundoplication, either anterior (180°) or posterior, should be performed only in patients with gastroesophageal reflux disease secondary to scleroderma and impaired esophageal motility, since the laparoscopic total fundoplication would impair esophageal emptying and cause dysphagia.

RESUMO A fundoplicatura total laparoscópica é considerada, atualmente, o padrão ouro para o tratamento cirúrgico da doença do refluxo gastroesofágico. Os resultados de curto prazo após a fundoplicatura total laparoscópica são excelentes, com recuperação rápida e morbidade perioperatória mínima. O alívio dos sintomas e o controle do refluxo são alcançados em cerca de 80 a 90% dos pacientes, 10 anos após a cirurgia. No entanto, é relatada uma incidência pequena, mas clinicamente relevante, de disfagia pós-operatória e sintomas relacionados a gases. Ainda existe debate sobre a melhor operação antirrefluxo e, nas últimas três décadas, os resultados cirúrgicos da fundoplicatura parcial laparoscópica (anterior ou posterior) foram comparados aos obtidos após uma fundoplicatura total laparoscópica. A fundoplicatura parcial laparoscópica, seja anterior (180°) ou posterior, deve ser realizada apenas em pacientes com doença do refluxo gastroesofágico secundária a esclerodermia e motilidade esofágica ineficiente, pois uma fundoplicatura total laparoscópica prejudicaria o esvaziamento esofágico e causaria disfagia.

O índice da taxa de fadiga é maior em crianças com constipação e incontinência fecal por retenção / The fatigue rate index is higher in children with functional constipation and retentive fecal incontinence

ABSTRACT Background: The Fatigue Rate Index (FRI) is a parameter in anorectal manometry (ARM) to assess sustained voluntary contraction, considering the squeeze pressure and fatigability of the external anal sphincter. It is used in adults to detect fecal incontinence even in patients who present normal squeeze pressures. The FRI in adult patients with functional constipation is similar to controls. Objective: The aim of this study was to evaluate the feasibility and values of FRI in children in relation to the values previously established in adults and comparing children with functional constipation and retentive fecal incontinence to children without retentive fecal incontinence. Methods: This retrospective study evaluated 105 ARM performed from Jan 2014 to Apr 2015. 42 patients were selected (were able to perform a voluntary contraction and had no co-morbidities other than functional constipation). 14 (33.3%) of those collaborated in sustaining contraction for 40 seconds (s), allowing the evaluation of the FRI. Patients with retentive fecal incontinence secondary to functional constipation (n=7, aged 6 to 13 years, six boys) were our interest group. Patients with functional constipation without fecal incontinence (n=7, aged 6 to 13 years, four boys) were considered a reference group. The ARM were performed with a radial eight-channel perfusion catheter (DynamedTM, São Paulo, Brazil) and the FRI was calculated (Proctomaster 6.4) in the first 20 s and overall 40 s of sustained voluntary contraction. Results: 14 of the selected 42 collaborated in sustaining contraction for 40 s, allowing the evaluation of the FRI. In the first 20 s of contraction, the fecal incontinence group showed a significantly higher mean FRI (2.48±1.39 min) compared to the reference group (1.13±0.72 min, P=0.042), which was not observed in the 40 s interval due to less uniform contraction. The anal resting pressure was higher in the fecal incontinence group (76.83 mmHg) than in the reference group (54.13 mmHg), but the statistical study did not reach significance (P=0.051). Conclusion: The FRI is feasible in children. The mean FRI obtained in this study is lower than the reported in constipated adults. The mean FRI among children with functional constipation and retentive fecal incontinence is higher than among constipated children without retentive fecal incontinence.

RESUMO Contexto O índice de Taxa de Fadiga (ITF) é um parâmetro na manometria anorretal (MAR) que é utilizado para avaliar a contração voluntária sustentada, considerando a pressão máxima de contração e a fatigabilidade do esfíncter anal externo. Este parâmetro é utilizado em adultos para diagnóstico da incontinência fecal mesmo entre paciente que apresentem pressões máximas de contração normais. O ITF em pacientes adultos com constipação é similar a controles. Objetivo: Avaliar a factibilidade e os valores do ITF em crianças com constipação e incontinência fecal por retenção em relação aos valores previamente estabelecidos para adultos, e comparar os dados das crianças com constipação intestinal funcional com e sem incontinência fecal por retenção. Métodos Este estudo retrospectivo avaliou 105 MAR realizadas de janeiro de 2014 a abril de 2015. 42 pacientes foram selecionados (foram capazes de realizar uma contração voluntária e não apresentavam outras comorbidades além da constipação). 14 destes pacientes cooperaram em manter a contração voluntária por 40 segundos, permitindo a avaliação do ITF. Pacientes com incontinência fecal por retenção secundária a constipação (n=7, 6 a 13 anos, seis meninos) constituíram nosso grupo de interesse. Pacientes com constipação funcional sem incontinência fecal por retenção. (n=7, 6 a 13 anos, quatro meninos) constituíram o grupo de referência. As MAR foram realizadas com cateter de perfusão de oito canais radiais (DynamedTM, São Paulo, Brazil) e o ITF foi calculado (Proctomaster 6.4) nos primeiros 20 segundos e também nos 40 segundos totais da contração voluntária sustentada. Resultados: Dos 42 pacientes selecionados, 14 (33%) colaboraram mantendo o platô de contração uniforme durante 40 segundos, permitindo a avaliação do ITF nos primeiros 20 segundos de contração, o grupo com incontinência fecal apresentou uma média de ITF significativamente mais alta (2,48±1,39 min) em comparação ao grupo de referência (1,13±0,72 min, P=0,042), o que não foi observado no intervalo de 40 segundos devido a contração menos uniforme. A pressão anal de repouso foi mais elevada no grupo com incontinência fecal (76,83 mmHg) do que no grupo de referência (54,13 mmHg), porém o estudo estatístico não atingiu significância (P=0,051). Conclusão: O ITF é factível em crianças. A média do ITF obtida neste estudo é mais baixa do que o reportado em adultos constipados (2,8 min). A média do ITF entre crianças constipadas com incontinência fecal por retenção fui superior ao do que observado em crianças constipadas sem incontinência fecal retentiva.

Estudo da fisiologia anorretal pré e pós terapia neoadjuvante para câncer de reto por manometria anorretal e escore de Jorge-Wexner / Study of anorectal physiology pre and pos neoadjuvant therapy for rectal cancer by anorectal manometry and jorge-wexner score

ABSTRACT Background: The treatment of distal rectal cancer may be accompanied by evacuation disorders of multifactorial etiology. Neoadjuvant chemoradiotherapy (NCRT) is part of the standard treatment for patients with locally advanced extraperitoneal rectal cancer. The assessment of anorectal function after long-term NCRT in patients with cancer of the extraperitoneal rectum has been poorly evaluated. Objective: The aim of the present study was to evaluate the effects of NCRT on anorectal function and continence in patients with extraperitoneal rectal cancer. Methods: Rectal adenocarcinoma patients undergoing neoadjuvant therapy were submitted to functional evaluation by anorectal manometry and the degree of fecal incontinence using the Jorge-Wexner score, before and eight weeks after NCRT. The manometric parameters evaluated were mean resting anal pressure (ARp), maximum voluntary contraction anal pressure (MaxSp) and average voluntary contraction anal pressure (ASp). All patients underwent the same NCRT protocol based on the application of fluoropyrimidine (5-FU) at a dosage of 350 mg/m2 associated with folic acid at a dosage of 20 mg/m2, intravenously, in the first and last week of treatment, concomitantly with conformational radiotherapy with a total dose of 50.4Gy, divided into 28 daily fractions of 1.8Gy. For statistical analysis of the quantitative variables with normal distribution, the mean, standard deviation, median and interquartile range were calculated. For comparison of two related samples (before and eight weeks after NCRT), Wilcoxon's non-parametric test was used. Results: Forty-eight patients with rectal cancer were included in the study, with a mean age of 62.8 (39-81) years, 36 (75%) of whom were male. The use of NCRT was associated with a decrease in the values of ARp (55.0 mmHg vs 39.1 mmHg, P<0.05) and ASp (161.9 mmHg vs 141.9 mmHg, P<0.05) without changing MaxSp values (185,5 mmHg vs 173 mmHg, P=0.05). There was no worsening of the incontinence score eight weeks after the use of NCRT (3.0 vs 3.3; P>0.05). Conclusion: NCRT was associated with a reduction in the values of ARp and the ASp. There was no change in MaxSp, as well as in the degree of fecal continence by the Jorge-Wexner score.

RESUMO Contexto: O tratamento do câncer retal distal pode ser acompanhado por distúrbios evacuatórios de etiologia multifatorial. A quimiorradioterapia neoadjuvante faz parte do tratamento padrão para pacientes com câncer retal extraperitoneal localmente avançado. A avaliação da função anorretal após neoadjuvância de longa duração em pacientes com câncer de reto extraperitoneal tem sido pouco estudada. Objetivo: O objetivo do presente estudo foi avaliar os efeitos da neoadjuvância na função anorretal e na incontinência em pacientes com câncer retal extraperitoneal. Métodos: Pacientes com adenocarcinoma de reto candidatos à terapia neoadjuvante foram submetidos a avaliação funcional por manometria anorretal e avaliação do grau de incontinência fecal pelo escore de Jorge-Wexner, pré e oito semanas após a neoadjuvância. Os parâmetros manométricos avaliados foram pressão anal média de repouso, pressão anal de contração voluntária máxima e pressão anal média de contração voluntária. Todos os pacientes foram submetidos ao mesmo protocolo de neoadjuvância baseado na aplicação de fluoropirimidina (5-FU) na dosagem de 350 mg/m2 associada ao ácido fólico na dosagem de 20 mg/m2, por via intravenosa, na primeira e última semana de tratamento, concomitantemente à radioterapia conformacional com dose total de 50,4Gy, dividida em 28 frações diárias de 1,8Gy. Para análise estatística das variáveis quantitativas com distribuição normal, foram calculados a média, desvio padrão, mediana e intervalo interquartil. Para comparação de duas amostras relacionadas (antes e oito semanas após a neoadjuvância, foi utilizado o teste não paramétrico de Wilcoxon. Resultados: Quarenta e oito pacientes com câncer retal foram incluídos no estudo, com média de idade de 62,8 (39-81) anos, sendo 36 (75%) do sexo masculino. O uso de neoadjuvância foi associado à diminuição dos valores de média de pressão de repouso (55,0 mmHg vs 39,1 mmHg, P<0,05) e média de pressão de contração voluntária (161,9 mmHg vs 141,9 mmHg, P<0,05) sem alterar os valores de pressão de contração voluntária máxima ((185,5 mmHg vs 173 mmHg, P=0.05)). Não houve piora do escore de incontinência oito semanas após o uso da quimiorradioterapia neoadjuvante (3,0 vs 3,3; P>0,05). Conclusão: A neoadjuvância associou-se à redução dos valores de média de pressão de repouso e média dos valores contração voluntária. Não houve alteração nos valores de contração voluntária máxima, bem como no grau de continência fecal pelo escore de Jorge-Wexner.

La disfagia fue el síntoma más frecuente (84, 76 y 100 por ciento en los tipos I, II y III, respectivamente). El 70 por ciento de los casos presentó más de un año de evolución de los síntomas. La media de la presión de relajación integrada estuvo por encima de 21 mmHg independientemente del tipo. No se encontraron pacientes con subtipos de la acalasia tipo III. Conclusiones: La manometría esofágica de alta resolución es útil para el diagnóstico y clasificación de la acalasia esofágica(AU)

Introduction: High-resolution esophageal manometry is the ideal test for the diagnosis of achalasia and shows the presence of tertiary waves or aperistalsis and increased pressure, in the absence of relaxation, of the lower esophageal sphincter. Objective: To assess the usefulness of high-resolution esophageal manometry in the diagnosis and classification of esophageal achalasia. Methods: A descriptive, cross-sectional investigation was carried out at the National Center for Minimal Access Surgery, between October 2018 and December 2019, in 46 patients with a diagnosis of esophageal achalasia. Those with previous esophageal surgery were excluded. The variables included were: age, sex, time of evolution, symptoms and manometric findings. For the analysis of the results, the percentage and measures of central tendency (arithmetic mean and standard deviation) were used. Results: Type II achalasia predominated in females (57 percent). Dysphagia was the most frequent symptom (84, 76, and 100 percent in types I, II, and III, respectively). 70 percent of the cases presented more than one year of evolution of the symptoms. Regarding the high-resolution manometry parameters, it was observed that regardless of the type, the mean integrated relaxation pressure was above 21 mmHg. No patients with type III achalasia subtypes were found. Conclusions: High-resolution esophageal manometry is useful for the diagnosis and classification of esophageal acalasia(AU)

Respostas pressóricas faringeana, esofágica e do esfíncter esofagiano a tarefas vocais à luz da manometria de alta resolução / Pharyngeal, upper esophageal sphincteric and esophageal pressures responses related to vocal tasks at the light of high resolution manometry

ABSTRACT BACKGROUND: High-resolution manometry (HRM) represents a potential tool for measuring pharyngoesophageal phonation pressures. OBJECTIVE: This study aims to evaluate pharyngeal, esophageal upper sphincteric and esophageal pressures during different phonation tasks. METHODS: 12 (six males, mean age 27 years) professional singers underwent HRM and produced four different vocal tasks at low, medium and high vocal loudness: vowel /ae/, ascending five note scale, word /hey/ and word /go/. Pressures were measured at pharynx, upper esophageal sphincter (UES) and esophagus. Visual analysis of the HRM topographic plots were performed. RESULTS: Esophageal pressures are higher during vocalization than at rest. Pharyngeal and UES phonation pressures does not differ significantly from rest pressures. Visual analysis of the topographic plots showed an important UES pressure increasement during phonation. CONCLUSION: HRM is a valuable tool for measuring pharyngoesophageal pressures during phonation. Esophageal pressures are higher during phonation than at rest and tend to increase with vocal loudness increment. The topographic plot provides additional data about phonatory mechanism physiology, especially at the UES region.

RESUMO CONTEXTO: A manometria de alta resolução (MAR) é uma ferramenta de grande potencial para mensuração das pressões faringoesofágicas durante a fonação. OBJETIVO: O estudo visa avaliar pressões faringianas, do esfíncter esofagiano superior e do esôfago durante manobras fonatórias. MÉTODOS: Doze (seis homens, idade média 27 anos) cantores profissionais foram submetidos à MAR e produziram quatro tarefas vocais em intensidade baixa, média e alta: vogal / ae /, escala ascendente de cinco notas, palavras /hey/ e /go/. Pressões aos níveis da faringe, esfíncter esofagiano superior e esôfago foram aferidas além de análise visual dos traçados. RESULTADOS: Pressões esofágicas foram maiores na vocalização que no repouso. Pressões da faringe e esfíncter esofagiano superior durante a fonação não foram diferentes que no repouso. Análise visual dos traçados mostrou importante incremento da pressão do esfíncter durante a fonação. CONCLUSÃO: MAR é uma ferramenta valiosa para mensurar as pressões faringoesofágicas durante a fonação. Pressões esofágicas são maiores durante a fonação que no repouso e tendem a aumentar com maior intensidade sonora. Análise visual dos traçados mostram dados adicionais sobre a fisiologia do mecanismo da fonação, especialmente na região do esfíncter esofagiano superior.

Manometría de alta resolución en pacientes con trastornos motores esofágicos / High resolution manometry in patients with esophageal motor disorders

Introducción: La manometría de alta resolución es la prueba de referencia para el estudio de los trastornos motores esofágicos. Objetivo: Determinar la factibilidad de la manometría de alta resolución para el estudio de las características de los trastornos motores esofágicos. Métodos: Se realizó una investigación descriptiva, transversal, en el Centro Nacional de Cirugía de Mínimo Acceso, entre septiembre de 2018 y diciembre de 2019, en 56 pacientes cubanos con diagnóstico de trastorno motor esofágico por manometría de alta resolución, con edades entre 18 y 80 años, que dieron su consentimiento para participar en el estudio. Se excluyeron pacientes con acalasia esofágica y los trastornos menores de la peristalsis. Las variables incluidas fueron: edad, sexo, diagnósticos manométricos y sus características, síntomas, tipos de unión esofagogástrica, diagnósticos imagenológicos o endoscópicos. Para el análisis de los resultados se empleó el porcentaje, medidas de tendencia central y ji cuadrado de Pearson de homogeneidad, con un nivel de significación p 8804; 0,05 y 95 por ciento de confiabilidad. Resultados: Predominó la contractilidad ausente (39,28 por ciento), el sexo femenino (58,9 por ciento) y la disfagia (66,07 por ciento). A la obstrucción al flujo de la unión esofagogástrica correspondió la media de presión de reposo del esfínter esofágico inferior más alta (43,28 mmHg) y la media de la presión de relación integrada por encima de 15 mmHg (38,88 mmHg). El esófago hipercontráctil presentó media de contractilidad distal integrada elevada (5564,25 mmHg/s/cm). Se comprobó la existencia de contracciones rápidas en el espasmo esofágico distal (media de 21,4 cm/ s). Conclusiones: La manometría de alta resolución es factible de ser empleada para el diagnóstico de los trastornos motores esofágicos(AU)

Introduction: High-resolution manometry is the gold standard for the study of esophageal motor disorders. Objective: A descriptive, cross-sectional research was carried out in el Centro Nacional de Cirugía de Mínimo Acceso, between September 2018 and December 2019, in 56 patients, diagnosed with esophageal motor disorder by high-resolution manometry, aged between 18 and 20 years, who gave their consent to participate in the study. Esophageal achalasia and minor peristalsis disorders were excluded. The variables included were: age, sex, manometric diagnoses and their characteristics, symptoms, types of esophagogastric junction, imaging or endoscopic diagnoses. For the analysis of the results, the percentage, measures of central tendency and Pearson's chi square of homogeneity were used, with a level of statistical significance 8804; 0.05 and 95 percent reliability. Development: Absent contractility (39,28 percent), female sex (58,9 percent) and dysphagia (66,07 percent) predominated. The obstruction to the flow of the esophagogastric junction corresponded to the highest mean resting pressure of the lower esophageal sphincter (43,28 mmHg) and the mean integrated pressure ratio above 15 mmHg (38,88 mmHg). The hypercontractile esophagus presented mean high integrated distal contractility (5564,25 mmHg/s/cm). Rapid contractions were found in distal esophageal spasm (mean 21,4 cm/s). Conclusions: High resolution manometry was feasible to be used for the diagnosis of major esophageal motor disorders(AU)

Caracterización de los trastornos manométricos esofágicos en pacientes con enfermedad por reflujo gastroesofágico refractario con síntomas esofágicos / Characterization of esophageal motility disorders in refractory gastroesophageal reflux disease patients with esophageal symptoms

Resumen Introducción: La enfermedad por reflujo gastroesofágico (ERGE) refractaria puede conducir a complicaciones potenciales como la esofagitis persistente, estenosis esofágica, anillo de Schatzki y esófago de Barrett. Este estudio describe la motilidad en pacientes con ERGE refractaria y su relación con síntomas esofágicos. Método: Se realizó un estudio observacional analítico a partir de una cohorte retrospectiva en pacientes con diagnóstico de ERGE refractaria y síntomas esofágicos a quienes se les realizó manometría esofágica de alta resolución más impedanciometría. Se describen las características clínicas y demográficas, y la asociación entre los trastornos manométricos y los síntomas esofágicos. Resultados: Se incluyeron 133 pacientes (edad promedio: 54,1 ± 12,5 años). La pirosis y regurgitación (69,2 %) y la disfagia esofágica (13,5 %) fueron los síntomas más comunes. La motilidad normal (75,2 %), el aclaramiento completo del bolo (75,2 %) y la motilidad esofágica inefectiva (MEI) (18 %) fueron los hallazgos manométricos más frecuentes. La unión gastroesofágica tipos II y IIIb estuvieron presentes en el 35,3% y 33,8 % de los casos, respectivamente. La aperistalsis (3,8 %) y el esófago en martillo neumático (Jackhammer; 0,8 %) fueron infrecuentes. El aclaramiento incompleto del bolo se asoció con disfagia esofágica (p = 0,038) y a MEI (p = 0,008). Ningún síntoma esofágico se relacionó significativamente con trastornos de motilidad. Conclusiones: Los resultados de nuestro estudio sugieren que los trastornos de motilidad son infrecuentes en los pacientes con ERGE refractaria. Adicionalmente, sugieren que la presencia de alteraciones de motilidad esofágica no se relaciona con la presencia de síntomas esofágicos y, por tanto, que el tipo de síntoma presentado no permite predecir la existencia de dichos trastornos.

Abstract Introduction: Refractory gastroesophageal reflux disease (GERD) can lead to potential complications such as persistent esophagitis, esophageal stricture, Schatzki ring, and Barrett's esophagus. This study describes motility in patients with refractory GERD, and its association with esophageal symptoms. Materials and methods: An analytical observational study was carried out in a retrospective cohort of patients diagnosed with refractory GERD and esophageal symptoms who underwent high-resolution esophageal manometry and impedance testing. Clinical characteristics, demographics, and the association between motility disorders and esophageal symptoms are described. Results: 133 patients were included (mean age 54.1 ± 12.5 years). Heartburn and regurgitation (69.2%), and esophageal dysphagia (13.5%) were the most common symptoms. Normal motility (75.2%), complete bolus clearance (75.2%), and ineffective esophageal motility (IEM) (18%) were the most frequent manometric findings. Type II and IIIb gastroesophageal junction were observed in 35.3% and 33.8% of the cases, respectively. Esophageal aperistalsis (3.8%) and Jackhammer esophagus (0.8%) were rare findings. Incomplete bolus clearance was associated with esophageal dysphagia (p=0.038) and IEM (p=0.008). No esophageal symptoms were significantly related to motility disorders. Conclusions: The results of the present study suggest that motility disorders are rare in patients with refractory GERD. They also suggest that esophageal motility disorders are not associated with the presence of esophageal symptoms and, therefore, the type of symptom experienced does not allow predicting the existence of such disorders.

Acalasia Cardia en Lactantes. Reporte de dos casos / Achalasia Cardia in Infants. Report of two cases

La acalasia es un trastorno neuromuscular de etiología desconocida que afecta el esófago y la unión esofagogástrica. Se caracteriza por aperistalsis del cuerpo del esófago y la falta de relajación del esfínter esofágico inferior. Es inusual en la infancia y extremadamente raro en lactantes. Presentamos el informe de dos lactantes de 5 meses y un año respectivamente que ingresaron ambos para estudio por cuadro de vómitos de contenido alimentario en forma progresiva. El diagnóstico se confirmó en el esofagograma y la rareza de los casos es que se pudo confirmar a través de la manometría de alta resolución (MAR) procedimiento difícil de realizar en estas edades y muy poco reportado en la literatura

Achalasia is a neuromuscular disorder of unknown etiology that affects the body of the esophagus and the esophagogastric junction. It is characterized by aperistalsis of the body of the esophagus and a lack of relaxation of the lower esophageal sphincter. It is unusual in childhood and extremely rare in infants. We present the report of two infants aged 5 months and 1 year respectively who were both admitted for study due to vomiting of food content progressively. The diagnosis was confirmed in the esophagogram and the rarity of the cases is that it could be confirmed through high resolution manometry (MAR), a procedure difficult to perform at these ages and extraordinarily little reported in the literature

Normal Values and Associated Factors in Highresolution Anorectal Manometry in Healthy Vietnamese Adults / Valores normais e fatores associados na manometria anorretal de alta resolução em adultos vietnamitas saudáveis

Abstract Introduction The present study aims to identify normal high-resolution anorectal manometry (HRAM) values and related factors in healthy Vietnamese adults. Methods The present cross-sectional study was conducted at the Viet Duc hospital, Hanoi, Vietnam, during April and May 2019. Healthy volunteers were recruited to participate in the study. Anorectal measurement values from the digestive tract, including pressure, were recorded. Results A total of 76 healthy volunteers were recruited. The mean functional anal canal length was 4.2 ± 0.5 cm, while the mean anal high-pressure zone length was 3.4 ± 0.5 cm. Themean defecation index was 1.4 ± 0.8, with values ranging from 0.3 to 5.0. The mean threshold volume to elicit the rectoanal inhibitory reflex (RAIR) was 18.1 mL. The mean rectal sensation values were 32.4mL, 81.6mL, and 159 mL for first sensation, desire to defecate, and urge to defecate, respectively. Dyssynergic patterns occurred in ~ 50% of the study participants and included mainly types I (27.6%) and III (14.6%). There were significant differences between male and female patients in terms of maximum anal squeeze pressure, maximum anal cough pressure, maximum anal strain pressure, maximum rectal cough pressure, and maximum rectal strain pressure (all p<0.01). Conclusions The present study establishes normal HRAM values in healthy Vietnamese adults, particularly regarding normal values of anorectal pressure and rectal sensation. Further studies that include larger sample sizes should be conducted to further confirm the constants and their relationships.

Cirurgia laparoscópica anti-refluxo: perguntas antigas foram respondidas ? é útil nos sintomas extra-esofágicos ? / Laparoscopic antireflux surgery: are old questions answered? useful for extra-esophageal symptoms?

RESUMO - RACIONAL: A doença do refluxo gastroesofágico geralmente está associada a sintomas esofágicos ou típicos, como azia, regurgitação e disfagia. No entanto, existem hoje evidências crescentes, que o refluxo gastroesofágico também pode causar problemas extraesofágicos ou atípicos, como tosse, pneumonia por aspiração e fibrose pulmonar. OBJETIVO: discutir a fisiopatologia dos sintomas extraesofágicos, avaliação diagnóstica, complicações e o resultado da cirurgia videolaparoscópica antirrefluxo. MÉTODOS: Análise de revisão recente da literatura. RESULTADOS: É importante separar os pacientes com sintomas respiratórios em dois grupos distintos: grupo I: pacientes que apresentam sintomas típicos como azia e sintomas respiratórios e grupo II: pacientes que apresentam apenas sintomas respiratórios, nos quais o refluxo é silencioso. CONCLUSÕES: O refluxo gastroesofágico pode causar sintomas respiratórios além dos sintomas esofágicos típicos. Elevado índice de suspeita deve estar presente e uma avaliação completa deve ser feita para diagnosticar se o refluxo patológico está presente e se ele se estende ao esôfago proximal ou faringe. A cirurgia anti-refluxo nesses pacientes deve ser considerada, pois é segura e eficaz.

ABSTRACT - BACKGROUND: Gastroesophageal reflux disease is usually associated with esophageal or typical symptoms such as heartburn, regurgitation, and dysphagia. However, there is today mounting evidence that gastroesophageal reflux can also cause extra-esophageal or atypical problems such as cough, aspiration pneumonia, and pulmonary fibrosis. AIM: The aim of this study was to discuss the pathophysiology of extra-esophageal symptoms, the diagnostic evaluation, complications, and the outcome of video laparoscopic antireflux surgery. METHODS: This study analyzes the recent literature review. RESULTS: It is important to separate patients with respiratory symptoms into two different groups: group I: patients having typical symptoms such as heartburn and respiratory symptoms, and group II: patients having respiratory symptoms only, in whom reflux is otherwise silent. CONCLUSIONS: Gastroesophageal reflux can cause respiratory symptoms in addition to esophageal typical symptoms. High index of suspicion should be present, and a complete workup was done to diagnose whether pathologic reflux is present and whether it extends to the proximal esophagus or pharynx. Antireflux surgery in these patients should be considered, as it is safe and effective.

Anorectal manometry standard of a brazilian population at productive age without pelvic floor disorders: a prospective volunteered study / Valores manométricos anorretais para a população brasileira eutrófica em idade produtiva e sem distúrbios do assoalho pélvico: estudo prospectivo com voluntários

ABSTRACT Background: Due to the lack of normal standards of anorectal manometry in Brazil, data used are subject to normality patterns described at different nationalities. Aim: To determine the values and range of the parameters evaluated at anorectal manometry in people, at productive age, without pelvic floor disorders comparing the parameters obtained between male and female. Methods: Prospective analysis of clinical data, such as gender, age, race, body mass index (BMI) and anorectal manometry, of volunteers from a Brazilian university reference in pelvic floor disorders. Results: Forty patients were included, with a mean age of 45.5 years in males and 37.2 females (p=0.43). According to male and female, respectively in mmHg, resting pressures were similar (78.28 vs. 63.51, p=0.40); squeeze pressures (153.89 vs. 79.78, p=0.007) and total squeeze pressures (231.27 vs. 145.63, p=0.002). Men presented significantly higher values of anorectal squeeze pressures, as well as the average length of the functional anal canal (2.85 cm in male vs. 2.45 cm in female, p=0.003). Conclusions: Normal sphincter pressure levels in Brazilians differ from those used until now as normal literature standards. Male gender has higher external anal sphincter tonus as compared to female, in addition a greater extension of the functional anal canal

RESUMO Racional: Devido à falta de padrões normais de manometria anorretal no Brasil, os dados utilizados estão sujeitos a padrões de normalidade descritos em diferentes nacionalidades . Objetivo: Determinar os valores e a faixa da manometria anorretal de pessoas em idade produtiva, sem distúrbios do assoalho pélvico, comparando os parâmetros obtidos entre homens e mulheres. Métodos: Análise prospectiva de dados clínicos, como gênero, idade, raça, índice de massa corporal (IMC) e manometria anorretal, de voluntários de uma referência universitária brasileira em distúrbios do assoalho pélvico. Resultados: Quarenta pessoas foram incluídas, com idade média de 45,5 anos nos homens e 37,2 nas mulheres (p=0,43). De acordo com homens e mulheres, respectivamente em mmHg, as pressões de repouso foram semelhantes (78,28 vs. 63,51, p=0,40); pressões de contração (153,89 vs. 79,78, p=0,007) e pressão total de compressão (231,27 vs. 145,63, p=0,002). Os homens apresentaram valores significativamente maiores de contração esfincteriana, assim como o comprimento médio do canal anal funcional (2,85 cm nos homens vs. 2,45 cm nas mulheres, p=0,003). Conclusões: Os níveis normais de pressão esfincteriana no Brasil diferem dos utilizados até o momento como padrão normal da literatura. O gênero masculino apresenta maior tônus ​​do esfíncter anal externo em relação ao feminino, além de maior extensão do canal anal funcional

Estudio comparativo de precisión diagnóstica preoperatoria y la confirmación laparoscópica de hernia hiatal / Comparative study of preoperative diagnostic precision and laparoscopic confirmation of hiatal hernia

Resumen Introducción: La hernia hiatal (HH) de tipo I por deslizamiento es el tipo más frecuente, siendo difícil de definir objetivamente, por lo que el principal foco de controversia es su diagnóstico. El objetivo del presente trabajo es reportar los resultados respecto de la precisión diagnóstica del estudio preoperatorio y confirmarlo con el diagnóstico laparoscópico de este tipo de HH. Materiales y Método: Estudio prospectivo descriptivo de serie que incluyen pacientes con síntomas típicos de enfermedad por reflujo gastroesofágico, los cuales se sometieron a estudio con esófago-gastro-duodenoscopía, estudio manométrico y radiológico de esófago, estómago y duodeno con bario. Se incluyen sólo los pacientes en los cuales la endoscopía revela la existencia de HH por deslizamiento ≪ 5 cm. Estos pacientes se sometieron a tratamiento quirúrgico confirmándose o no la existencia de HH al momento de la exploración laparoscópica. Resultados: El valor predictivo positivo y sensibilidad para manometría fue de un 51,2% y 70%, para la radiología 91,7% y 80,5% y para endoscopia 80,3% y 70,7% respectivamente. Conclusión: Para el diagnóstico confiable de HH antes del tratamiento, las tres investigaciones mencionadas deben ser obligatorias antes de la cirugía.

Introduction: Being type I hiatal hernia (HH) the most frequent, is difficult to define objectively and therefore, the main focus of controversy is the diagnosis. The aim of this paper is to report the results regarding the diagnostic accuracy of the preoperative study and to confirm it with the laparoscopic diagnosis of hiatal hernia. Materials and Method: This descriptive and prospective study includes patients with typical symptoms of gastroesophageal reflux disease who underwent esophageal-gastro-duodenoscopy, manometry and radiological study of esophagus with barium swallow. Only patients in whom endoscopy reveals the existence of HH by sliding ≪ 5 cm are included. These patients underwent surgical treatment confirming or not the existence of HH at the time of laparoscopic exploration. Results: The positive pre- dictive value and sensibility for manometry was 51.2% and 70%, for radiology 91.7% and 80.5%, and for endoscopy 85.3% and 70.7% respectively. Conclusion: For the reliable diagnosis of HH before treatment, the three mentioned investigations must be mandatory before the surgery.
