Achalasia and its subtypes: a Moroccan cohort in Ibn Sina Hospital, Rabat

Introduction: achalasia is an esophageal motility disorder, characterized by irregular peristalsis and inadequate relaxation of the lower esophageal sphincter, typically manifests with dysphagia as its primary symptom. The advent of high-resolution manometry (HRM) has transformed our comprehension of achalasia. It has delineated three distinct subtypes based on variations in pressurization and contractions, contributing significantly to the understanding of this condition. This study aimed to describe and compare clinically and manometrically the patients suffering from the different subtypes of achalasia. Methods: it is a retrospective single-center study including all patients with achalasia diagnosed by high-resolution manometry (HRM) between April 2018 and January 2023. The diagnosis was retained based on the latest Chicago 3.0 classification. Results: out of 103 patients, 25.2% (n=26) had type I achalasia, 66.9% (n=69) type II, and 7.8% (n=8) type III. Patients with type I and II achalasia were younger than patients with type III achalasia (mean age 43.2 years vs. 55.6 years, P=0.0053). A female predominance was found in type I achalasia and a male predominance in type III. The most frequent symptoms were: dysphagia (found in all our patients). At HRM, all our patients had a pathological IRP with a mean of 26.95 mmHg for the 3 types of achalasia. Resting IBS pressures were higher in patients with type III achalasia compared to types I and II (35.28 mmHg vs 32.7 mmHg and 31.04 mmHg, P=0.40). Conclusion: achalasia is one of the most studied esophageal motility disorders. Tools such as HRM have permitted us not only to identify achalasia early but also to define different subtypes, which can have therapeutic implications.

The normal values of water-perfused high resolution esophageal manometry: a multicenter study / 中华消化杂志

Objective:To establish the normal values of water-perfused high resolution esophageal manometry (HREM)(GAP-36A) at resting period, water swallowing, semisolid swallowing and solid swallowing in Chinese population.Methods:From September 1, 2019 to June 30, 2020, 91 healthy volunteers receiving water-perfused HREM (GAP-36A) at resting period, water swallowing, semisolid swallowing and solid swallowing were selected from 9 hospitals (Union Hospital, Tongji Medical College, Huazhong University of Science and Technology; the First Affiliated Hospital of Dalian Medical University; the Second Hospital of Hebei Medical University; the Second Affiliated Hospital, Naval Medical University; the First Affiliated Hospital, Sun Yat-sen University; the First Affiliated Hospital, University of Science and Technology of China; Aviation General Hospital of China Medical University; the Affiliated Hospital of Medical School of Nanjing University and the First People′s Hospital of Yichang). Parameters included the position of the upper and lower edges of the upper esophageal sphincter (UES) and lower esophageal sphincter (LES), the length of the LES and UES, the position of the pressure inversion point (PIP), the resting pressure of UES and LES and swallow-related parameters such as the distal contraction integral (DCI), 4 s integrated relaxation pressure (IRP), distal latency (DL) and UES residual pressure. One-way analysis of variance, post-hoc test and sum rank test were used for statistical analysis.Results:A total of 87 healthy volunteers were enrolled, including 40 males and 47 females, aged (38.5±14.2) years old (ranged from 19 to 65 years old). The position of the upper and lower edges of the LES was (42.7±2.8) and (45.6±2.8) cm, respectively, the length of the LES was (2.9±0.4) cm, and the position of PIP was (43.3±2.8) cm. The position of the upper and lower edges of the UES was (18.1±3.0) and (22.6±2.0) cm, respectively, and the length of the UES was (4.8±1.0) cm. The resting pressure of LES and UES was (17.4±10.7) and (84.1±61.1) mmHg (1 mmHg=0.133 kPa), respectively. The DCI value at solid swallowing was higher than those at water swallowing and semisolid swallowing ((2 512.4±1 448.0) mmHg·s·cm vs. (2 183.2±1 441.2) and (2 150.8±1 244.8) mmHg·s·cm), and the differences were statistically significant ( t=-4.30 and -3.74, both P<0.001). The values of 4 s IRP at semisolid swallowing and solid swallowing were lower than that at water swallowing ((4.6±4.1) and (4.9±3.9) mmHg vs. (5.4±3.9) mmHg), and the differences were statistically significant ( t=3.38 and 2.09, P=0.001 and 0.037). The DL at water swallowing was shorter than those at semisolid swallowing and solid swallowing ((8.5±1.8) s vs. (9.8±2.2) and (10.6±2.8) s), and the DL at semisolid swallowing was shorter than that at solid swallowing, and the differences were statistically significant ( t=-10.21, -13.91 and -4.68, all P<0.001). The UES residual pressure at water swallowing was higher than those at semisolid swallowing and solid swallowing (9.5 mmHg, 6.5 to 12.3 mmHg vs. 8.0 mmHg, 4.5 to 11.7 mmHg and 5.5 mmHg, 2.0 to 9.3 mmHg), and the UES residual pressure at semisolid swallowing was higher than that at solid swallowing, and the differences were statistically significant ( t=3.48, 10.30 and 6.35, all P<0.001). Conclusions:The normal values of water-perfused HREM (GAP-36A) in Chinese population at resting period, water swallowing, semisolid swallowing and solid swallowing can provide a reference basis for clinical diagnosis and treatment for patients receiving water-perfused HREM examination.

La manometría de alta resolución en los trastornos motores del esófago Introducción en Cuba / High-resolution manometry for diagnosis of esophageal motor disorders. Introduction in Cuba

RESUMEN: Introducción: La manometría esofágica de alta resolución se considera a nivel internacional como un método óptimo para el diagnóstico de los trastornos motores del esófago, de alta especificidad y sensibilidad. Dada la reciente introducción de la técnica en Cuba, se necesita demostrar su utilidad en nuestro país, donde no existe grado de conocimiento previo sobre cuáles son los parámetros de normalidad, así como los diagnósticos de alta resolución más frecuentes. Objetivo: Determinar la utilidad de la manometría esofágica de alta resolución como estudio diagnóstico para los trastornos motores del esófago en Cuba. Métodos: Se diseñó una investigación aplicada, de desarrollo, realizada en el Centro Nacional de Cirugía de Mínimo Acceso, en La Habana, entre junio de 2017 y junio de 2019, en pacientes a los que se les realizó una manometría esofágica. El universo de pacientes fue 611, a quienes se les registraron las variables en estudio. Resultados: De las 611 manometrías esofágicas, 356 correspondían a mujeres (58,3 por ciento) y 255 a hombres (42,7 por ciento), con un promedio de edad de 47, 44 años respectivamente. La motilidad inefectiva fue el trastorno motor más frecuente (32,73 por ciento). En los pacientes con Enfermedad por Reflujo Gastroesofágico, el principal daño de la barrera antirreflujo fue la presencia de relajaciones transitorias del esfínter esofágico inferior. Predominó la Acalasia tipo II (5,23 por ciento). En estos pacientes se registraron valores de Presión de relajación integrada (IRP) por encima de 21. Conclusiones: Se establecieron valores aplicables a pacientes cubanos, que permiten establecer el diagnóstico por alta resolución(AU)

ABSTRACT Introduction: High-resolution esophageal manometry is considered internationally as an optimal method for diagnosis of esophageal motor disorders. Given the recent introduction of the technique in Cuba, it is necessary to demonstrate its usefulness in our country where there is no prior knowledge about the most frequent parameters of normality and high resolution diagnoses. Objective: To determine the usefulness of high-resolution esophageal manometry as a method for the diagnosis of esophageal motor disorders in Cuba. Material and methods: An applied developmental research was designed and carried out at the National Center for Minimal Access Surgery in Havana between June 2017 and June 2019. The study included patients in whom esophageal manometry was performed. The universe consisted of 611 patients and the variables used in the study were recorded. Results: Of the 611 patients who underwent esophageal manometry, 356 were women (58.26 percent) and 255 were men (42.73 percent), with an average age of 47 and 44 years, respectively. Ineffective motility was the most frequent motor disorder (32,73 percent). In patients with Gastroesophageal Reflux Disease, the main damage of the antireflux barrier was the presence of transient lower esophageal sphincter relaxations. Type II achalasia predominated (5,23 percent). In these patients, integrated relaxation pressure (IRP) values above 21 were recorded. Conclusions: Values applicable to Cuban patients that allow to establish a high-resolution diagnosis were established(AU)

Nuevas tecnologías endoscópicas y ética médica / New endoscopic technologies and medical ethics

La revolución científico técnica desempeñó un papel fundamental en la introducción de nuevas tecnologías en las ciencias médicas y en específico en la gastroenterología. Dicho progreso en las tecnologías no debe dejar de lado la parte ética de la relación médico paciente y el principio de no hacer daño. A esta disyuntiva se enfrenta el gastroenterólogo cuando debe decidir, tratar a un paciente con una técnica endoscópica, que es menos invasiva, o remitirlo para el médico cirujano. Con el objetivo de determinar el impacto de las nuevas tecnologías endoscópicas en las ciencias después de la revolución científico técnica, así como establecer los factores que atentan contra las buenas prácticas de la cirugía endoscópica endoluminal y su repercusión en los pacientes en el panorama nacional; se realizó un análisis de los beneficios de los adelantos tecnológicos en la endoscopía terapéutica, la manometría esofágica y la cirugía de mínimo acceso en Cuba y su repercusión en las cualidades éticas que deben caracterizar al médico, contenidas en el juramento hipocrático. Se concluye que la cirugía endoscópica endoluminal ha creado una nueva dimensión en el tratamiento de las lesiones del tubo digestivo y en sus años de existencia se tiene la experiencia suficiente para afrontar los retos del futuro con profesionalidad y humanismo(AU)

The scientific-technical revolution played a fundamental role in the introduction of new technologies in medical sciences and specifically in Gastroenterology. Such progress in technologies should not leave aside the ethical part of the doctor-patient relationship and the principle of not doing harm. The gastroenterologist faces this dilemma when he must decide to treat a patient with an endoscopic technique, which is less invasive, or refer it to the surgeon. With the objective of determining the impact of new endoscopic technologies in the sciences after the scientific and technical revolution; as well as establishing the factors that undermine the good practices of endoluminal endoscopic surgery and its impact on patients in the national scenario. An analysis was made of the benefits of technological advances in therapeutic endoscopy, esophageal manometry and minimum access surgery in Cuba and its impact on the ethical qualities that should characterize the physician, making a critical analysis at the beginning of the oath Hippocratic. It is concluded that endoluminal endoscopic surgery has created a new dimension in the treatment of digestive tract injuries and in its years of existence has sufficient experience to face the challenges of the future with professionalism and humanism(AU)

Validation of a new water-perfused high-resolution manometry system / Validação de um novo sistema de manometria de alta resolução por perfusão de água

ABSTRACT Background: High-resolution manometry is more costly but clinically superior to conventional manometry. Water-perfused systems may decrease costs, but it is unclear if they are as reliable as solid-state systems, and reference values are interchangeable. Aim: To validate normal values for a new water-perfusion high-resolution manometry system. Methods: Normative values for a 24-sensors water perfused high-resolution manometry system were validated by studying 225 individuals who underwent high resolution manometry for clinical complaints. Patients were divided in four groups: group 1 - gastroesophageal reflux disease; group 2 - achalasia; group 3 - systemic diseases with possible esophageal manifestation; and group 4 - dysphagia. Results: In group 1, a hypotonic lower esophageal sphincter was found in 49% of individuals with positive 24 h pH monitoring, and in 28% in pH-negative individuals. In groups 2 and 3, aperistalsis was found in all individuals. In group 4, only one patient (14%) had normal high-resolution manometry. Conclusions: The normal values determined for this low-cost water-perfused HRM system with unique peristaltic pump and helicoidal sensor distribution are discriminatory of most abnormalities of esophageal motility seen in clinical practice.

RESUMO Racional: A manometria de alta resolução é mais custosa, porém clinicamente superior à manometria convencional. Sistemas por perfusão de água podem ter custo diminuído, mas não é certo se são tão eficazes quanto aos sistemas de estado sólido e se os valores de referência são intercambiáveis. Objetivo: Este estudo visa validar valores de normalidade para um novo sistema por perfusão de água. Método: Valores de normalidade para um sistema de manometria de alta resolução de 24 sensores por perfusão de água foram validados estudando 225 indivíduos submetidos à manometria de alta resolução por queixas clínicas. Pacientes foram divididos em quatro grupos: grupo 1 - doença do refluxo gastroesofágico; grupo 2 - acalasia; grupo 3 - doenças sistêmicas com possível doenças sistêmicas com comprometimento esofágico; e grupo 4 - pacientes com disfagia. Resultado: No grupo 1, esfíncter esofagiano inferior hipotônico foi encontrado em 49% dos indivíduos com pHmetria positiva e 28% daqueles com pHmetria negativa. Nos grupos 2 e 3, aperistalse foi encontrada em todos indivíduos. No grupo 4, somente um paciente (14%) tinha manometria normal. Conclusão: Os valores de normalidade definidos para este sistema de manometria de alta resolução por perfusão de água são discriminatórios da maioria das anormalidades da motilidade esofágica vistas na prática clínica.

Does the nissen fundoplication procedure improve esophageal dysmotility in patients with barrett's esophagus? / A fundoplicatura a nissen melhora a dismotilidade esofágica em pacientes com esôfago de barrett?

ABSTRACT Objective: to evaluate esophageal dysmotility (ED) and the extent of Barrett's esophagus (BE) before and after laparoscopic Nissen fundoplication (LNF) in patients previously diagnosed with BE and ED. Methods: twenty-two patients with BE diagnosed by upper gastrointestinal (GI) endoscopy with biopsies and ED diagnosed by conventional esophageal manometry (CEM) were submitted to a LNF, and followed up with clinical evaluations, upper GI endoscopy with biopsies and CEM, for a minimum of 12 months after the surgical procedure. Results : sixteen patients were male (72.7%) and six were females (27.3%). The mean age was 55.14 (± 15.52) years old. and the mean postoperative follow-up was 26.2 months. The upper GI endoscopy showed that the mean length of BE was 4.09 cm preoperatively and 3.91cm postoperatively (p=0.042). The evaluation of esophageal dysmotility through conventional manometry showed that: the preoperative median of the lower esophageal sphincter resting pressure (LESRP) was 9.15 mmHg and 13.2 mmHg postoperatively (p=0.006). The preoperative median of the esophageal contraction amplitude was 47.85 mmHg, and 57.50 mmHg postoperatively (p=0.408). Preoperative evaluation of esophageal peristalsis showed that 13.6% of the sample presented diffuse esophageal spasm and 9.1% ineffective esophageal motility. In the postoperative, 4.5% of patients had diffuse esophageal spasm, 13.6% of aperistalsis and 22.7% of ineffective motor activity (p=0.133). Conclusion: LNF decreased the BE extension, increased the LES resting pressure, and increased the amplitude of the distal esophageal contraction; however, it was unable to improve ED.

RESUMO Objetivo: avaliar a dismotilidade esofágica (DE) e a extensão do esôfago de Barrett (EB) antes e depois da fundoplicatura laparoscópica a Nissen (FLN) em pacientes previamente diagnosticados com EB e DE. Método: vinte e dois pacientes com EB diagnosticada por endoscopia digestiva alta (EDA) com biópsias e DE diagnosticada por manometria esofágica convencional (MEC) foram submetidos a FLN, e acompanhados por avaliações clínicas, endoscopia digestiva alta com biópsias e MEC, por no mínimo 12 meses após o procedimento cirúrgico. Resultados: dezesseis pacientes eram do sexo masculino (72,7%) e seis do feminino (27,3%). A média de idade foi de 55,14 (± 15,52) anos e o seguimento pós-operatório médio foi de 26,2 meses. A endoscopia digestiva alta mostrou que o comprimento médio do EB foi de 4,09 cm no pré-operatório e 3,91 cm no pós-operatório (p = 0,042). A avaliação da dismotilidade esofágica por meio da manometria convencional mostrou que a mediana pré-operatória da pressão de repouso do esfíncter esofágico inferior (PREEI) foi de 9,15 mmHg, e de 13,2 mmHg no pós-operatório (p = 0,006). A mediana pré-operatória da amplitude de contração esofágica foi de 47,85 mmHg, e de 57,50 mmHg no pós-operatório (p = 0,408). A avaliação pré-operatória do peristaltismo esofágico mostrou que 13,6% da amostra apresentava espasmo esofágico difuso e 9,1%, motilidade esofágica ineficaz. No pós-operatório, 4,5% dos pacientes apresentaram espasmo esofágico difuso, 13,6% de aperistalse e 22,7% de atividade motora ineficaz (p = 0,133). Conclusões: a FLN diminuiu a extensão do EB, aumentou a pressão de repouso do EEI e aumentou a amplitude da contração esofágica distal; no entanto, não foi capaz de melhorar a DE.

Twenty-Four Hour pH Study and Manometry in Gastric Esophageal Substitutes in Children / 대한소아소화기영양학회지

PURPOSE: Studies on the physiology of the transposed stomach as an esophageal substitute in the form of a gastric pull-up or a gastric tube in children are limited. We conducted a study of motility and the pH of gastric esophageal substitutes using manometry and 24-hour pH measurements in 10 such patients. METHODS: Manometry and 24 hour pH studies were performed on 10 children aged 24 to 55 months who had undergone gastric esophageal replacement. RESULTS: Six gastric tubes (4, isoperistaltic; 2, reverse gastric tubes) and 4 gastric pull-ups were studied. Two gastric tubes and 4 gastric pull-ups were transhiatal. Four gastric tubes were retrosternal. The mean of the lowest pH at the midpoint of the substitute was 4.0 (range, 2.8–5.0) and in the stomach remaining below the diaphragm was 3.3 (range, 1.9–4.2). In both types of substitute, the difference between the peak and the nadir pH recorded in the intra-thoracic and the sub-diaphragmatic portion of the stomach was statistically significant (p < 0.05), with the pH in the portion below the diaphragm being lower. The lowest pH values in the substitute and in the remnant stomach were noted mainly in the evening hours whereas the highest pH was noted mainly in the morning hours. All the cases showed a simultaneous rise in the intra-cavitatory pressure along the substitute while swallowing. CONCLUSION: The study suggested a normal gastric circadian rhythm in the gastric esophageal substitute. Mass contractions occurred in response to swallowing. The substitute may be able to effectively clear contents.

Symptom characteristics and esophageal motility of patients with different types of gastroesophageal junction / 中华消化杂志

Objective To investigate the symptom,esophageal motility characteristics and the prevalence of gastroesophageal reflux disease(GERD)in patients with typeⅠ,Ⅱand Ⅲ gastroesophageal junction (EGJ)diagnosed by high resolution esophageal manometry(HREM).Methods From 6th January to 27th December in 2012,the clinical data of 171 patients with reflux symptoms and received HREM were retrospectively analyzed.According to the Chicago classification V.3.0,the patients were divided into EGJ type Ⅰ,Ⅱ and Ⅲ groups.The age,body mass index(BMI),GERD related symptoms,esophageal motility parameters and the incidence of GERD were compared among the three groups.Chi-square test, t test and analysis of variance were used for statistical analysis.Relationship between EGJ types and other variables were analyzed by Spearman rank correlation.Results In 171 patients,136 cases(79.5%)with type Ⅰ EGJ,22 cases(12.9%)with type Ⅱ EGJ and 13 cases(7.6%)with type Ⅲ EGJ.The age of patients with type Ⅱ EGJ was significantly older than that of patients with type Ⅰ EGJ((56.5 ± 2.3) years vs(48.6 ± 1.0)years,t=2.992,P=0.003),however the differences were not statisticant when compared with type Ⅲ EGJ patients((51.2 ± 3.8)years,P> 0.05).The BMI of patients with typeⅢ EGJ was higher than that of typeⅠand typeⅡEGJ patients((26.0 ± 1.3)kg/m2vs(21.9 ± 0.3)kg/m2and (23.5 ± 0.6)kg/m2),and the difference was statistically significant(t=4.082 and 2.108,both P<0.05). The resting pressure of lower esophageal sphincter(LES)of patients with type Ⅱ and Ⅲ EGJ were lower than that of typeⅠEGJ((10.6 ± 1.5)mmHg(1 mmHg=0.133 kPa)and(3.4 ± 0.7)mmHg vs(17.1 ± 0.7)mmHg),and the resting pressure of LES of type Ⅲ EGJ was lower than that of type Ⅱ EGJ((3.4 ± 0.7)mmHg vs(10.6 ± 1.5)mmHg),and the differences were all statistically significant(t= -3.882,-6.411 and -2.769,all P< 0.01).The amplitude of contraction at 11 cm above LES and distal contractile integral(DCI)of patients with type Ⅲ EGJ were both lower than those of patients with typeⅠ EGJ((32.2 ± 5.4)mmHg vs(48.5 ± 2.5)mmHg,and(392.0 ± 94.1)mmHg·s·cm vs(805.1 ± 61.4)mmHg·s·cm),and the differences were statistically significant(t= -2.580 and -2.041,both P<0.05).The incidences of GERD in patients with type Ⅰ,Ⅱ and Ⅲ EGJ were 68.4%(93/136), 77.3%(17/22)and 10/13,respectively,and the difference was not statistically significant(χ2 =1.021, P=0.600).EGJ types were positively correlated with age and BMI(r= 0.214 and 0.290,both P<0.01).However,EGJ types were negatively correlated with the LES resting pressure,contraction amplitudes at 7 cm and 11 cm above the LES,and DCI(r= -0.474,-0.182,-0.333 and -0.191,all P<0.05).Conclusions Aging,overweight and obesity are risk factors of the LES and crural diaphragm separation.EGJ types are not predictable based on symptoms.The esophageal motility seems to decrease in patients with type Ⅱ and Ⅲ EGJ,the incidence of GERD in patients with type Ⅰ,Ⅱ and Ⅲ EGJ are all high.

Resultados de la manometría del cuerpo esofágico y del asa de yeyuno en pacientes operados por cáncer gástrico con gastrectomía total 5 años después de la cirugía / Esophageal manometry in patients with total gastrectomy 5 years after surgery

Resumen Introducción: La técnica de elección para la reconstrucción del tránsito intestinal después de una gastrectomía total es la esófago-yeyuno anastomosis en Y de Roux, la cual evita el reflujo de jugo digestivo alcalino. El objetivo del presente estudio es el de analizar la motilidad del esófago y del asa de yeyuno en pacientes operados con gastrectomía total por cáncer gástrico. Pacientes y método: Se estudió prospectivamente una muestra de 17 pacientes intervenidos mediante gastrectomía total 5 años atrás. En todos ellos se realizaron manometrías esofágicas de alta resolución incluyendo los primeros 7 cm del asa de yeyuno. Resultados: Los resultados de la manometría demostraron motilidad esofágica normal a excepción de la presión máxima intrabolo, la cual se encontraba aumentada en todos los pacientes. La motilidad del asa de yeyuno fue desordenada e inefectiva. Conclusiones: La motilidad del cuerpo esofágico es normal 5 años después de la gastrectomía total. Sin embargo, la presión intrabolo máxima se encuentra aumentada; la causa más probable de este hecho estaría constituida por el asa de yeyuno, que ejerce resistencia al paso del bolo debido a que presenta una actividad motora desordenada y poco propulsiva. El impacto clínico de este hecho es, sin embargo, poco importante.

Abstract Introduction: The most preferred technique to reconstruct the intestinal transit after total gastrectomy for gastric cancer is the Roux-en-Y esophagus-gastrostomy which prevents the reflux of alkaline intestinal juice. The purpose of this study was to analyze the esophageal motility and the motility of the jejunal loop in patients subjected to total gastrectomy. Patients and method: A prospective sample of 17 total gastrectomy patients operated on 5 years before was studied using high resolution esophageal manometry including the first 7 cm of the jejunal loop. Results: Manometry results showed normal esophageal body motility with the exception of the maximum intrabolus pressure that was elevated in all patients. The jejunal loop motility was disordered and ineffective. Conclusions: Esophageal body motility was normal 5 years after the surgical procedure. However, maximum intrabolus pressure was elevated and the most plausible reason would be the jejunal loop that exerts resistance to the bolus passage due to its ineffective motility. However, this fact does not have a significant clinical impact.

The esophageal manometry registered the poor relaxation of the lower esophageal sphincter and no peristalsis. Conclusions: The disease typical features were identified, on being important the dysphagia patient's clinical follow-up in order to have a final diagnosis of the disease(AU)

A analysis on the monitoring results of high resolution esophageal manometry and 24-Hour impedance-pH for the patients with functional heartburn and non-erosive reflux disease / 中国医学装备

Objective:To analyze the monitoring results of high resolution esophageal manometry (HRM) and 24-Hour impedance-pH for the patients with functional heartburn (FH)and non-erosive reflux disease(NERD), and explore the effect of Gastroesophageal junction morphology, transient lower esophageal sphincter relaxation and regurgitation of gastric acid in FH and NERD.Methods: 86 patients with continuous heartburn who were negative under endoscope were divided into FH group(38cases) and NERD group(48cases), and gastrointestinal symptom rating scales (GSRS), the results of HRM and 24h pH/impedance monitoring of the two groups were compared and analyzed.Results: The GSRS of sour regurgitation, abdominal distension, diarrhea and constipation of FH group were significantly higher than that of NERD group, respectively(t=-4.45,t=3.83,t=3.07,t=4.58,P<0.05). The ratio of esophagogastric junction-III(EGJ-III)of FH group was significantly lower than that of NERD group (Z=-3.27,P<0.05). And the ratio of esophageal hiatus hernia of FH group was significantly lower than that of NERD group(x2=16.01,P<0.05). In HRM parameters, the differences of lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure(UESP), distal contractile integral(DCI)and esophagogastric junction- contractile integral (EGJ-CI) between FH group and NERD group were statistically significant(t=6.99,t=-4.51,t=-2.91,t=-3.72;P<0.05), respectively. On the other hand, the times of sour regurgitation in erect position, the ratio of fluid regurgitation, exposed time of erect position and clinostatism, and DeMeester integral of NERD group was statistically significant higher than that of FH group(t=-9.48,t=-13.00,t=-13.56,t=-18.31;P<0.05).Conclusion:There are esophageal dysfunction in a certain degree and obvious regurgitation in both of two groups, and the detections of HRM and 24h-impedance pH contribute to differential diagnosis for NERG. Besides, the symptom of patients with FH may be relative with regurgitation of non-acidic material, especially may be relative with regurgitation of air.

Effects of different food bolus on esophageal motility in patients with non-obstructive esophageal dysphagia / 中华消化杂志

Objective To analyze the effects of different food bolus on esophageal motility in patients with non-obstructive esophageal dyshagia by high-resolution esophageal manometry.Methods From March 2014 to June 2015,48 patients with non-obstructive esophageal dysphagia and 12 healthy volunteers (healthy control group) were enrolled.High-resolution manometry was tested when swallowing liquid food,semisolid food and solid food.The lower esophageal sphincter pressure (LESP),4 second integrated relaxation pressure (4 s IRP),distal contractile integral (DCI),distal latency (DL),and breaks were analyzed.T test was performed for statistical analysis.Results According to the 2014 Chicago classification standard,among 48 patients with dysphagia,esophageal dysmotility was diagnosed in 35 patients (72.9％),while 13 patients (27.1％) had normal esophageal motility,and the most common type of esophageal motility disorder was ineffective esophageal motility (31.2％,15/48).The LESP of the healthy control group was (10.85±3.75) mmHg (1 mmHg=0.133 kPa) and 4 s IRP was (1.90±0.84) mmHg.The LESP of dysphagia group was (12.20 ±8.93) mmHg and 4 s IRP was (3.25± 1.02) mmHg.There was no significant difference in LESP and 4 s IRP between two groups (both P＞0.05).The DCIs of liq(u)id swallows,semisolid swallows and solid swallows of healthy control group were (589.00±292.90),(690.17±52.41) and (808.00±448.53) mmHg · s · cm,respectively,which were significantly lower than those of complete normal group in Chicago classification ((1 346.62 ± 244.83),(1 542.46±231.19) and (1 890.31±363.26) mmHg · s · cm;t=4.76,4.68 and 3.79;all P=0.001).The DL of solid swallows of healthy control group was (7.72± 1.15) s,which was significantly lower than that of complete normal group in Chicago classification ((9.00±1.23) s;t=2.61,P=0.021).The breaks of liquid swallows,semisolid swallows and solid swallows of healthy control group were (2.33 ±1.74),(2.37±1.72) and (1.53± 1.22) cm,respectively,which were higher than those of complete normal group in Chicago classification ((0.58±0.48),(0.52±0.47) and (0.85±0.53) cm),and the differences were statistically significant (t =3.02,3.68 and 2.54,all P ＜ 0.05).Conclusions The most common type of esophageal motility disorder in patients with non-obstructive esophageal dysphagia is ineffective esophageal molitity.When swallowing food,the patients with dysphagia but normal results of esophageal manometry according to Chicago classification require more strength of the esophagus,more complete contraction and longer peristaltic time to swallow food bolus.

Cómo realizar e interpretar una manometría esofágica de alta resolución usando la clasificación de Chicago 3. 0 / How to perform and interpret a high resolution esophageal manometry using the Chicago 3.0 classification

Resumen Con la introducción de la manometría esofágica de alta resolución se revelaron patrones no identificados previamente de la función esofágica. De igual forma, este método diagnóstico adiciona patrones de presión topográfica de la presión esofágica, lo que lleva al desarrollo de nuevas herramientas para el análisis y clasificación de desórdenes motores esofágicos. En la actualidad, la clasificación de Chicago 3.0 es la herramienta de análisis de los diferentes trastornos motores esofágicos. En Colombia, cada día se ve el crecimiento en la realización de este estudio. El artículo propone hacer una revisión de cómo realizar e interpretar una manometría esofágica de alta resolución y clasificar los diferentes trastornos de la motilidad esofágica según la última actualización de la clasificación de Chicago 3.0.

Abstract The introduction of high resolution esophageal manometry has led to the revelation of previously unidentified patterns of esophageal function. Similarly, this diagnostic method has revealed topographic patterns of esophageal pressure which has led to the development of new tools for analysis and classification of esophageal motility disorders. Currently, the Chicago 3.0 classification has become a tool for analysis of the various esophageal motility disorders. In Colombia, the use of this study is spreading and growing. This article reviews of how to perform and interpret high resolution esophageal manometry and shows how to classify esophageal motility disorders according to the latest update of Chicago 3.0.

Esófago en martillo neumático (Jackhammer), serie de casos y revisión del tema / Case Studies and Review of Jackhammer Esophagus

El esófago en martillo neumático (Jackhammer) es un trastorno peristáltico de hipercontractilidad, que de acuerdo con la clasificación de Chicago v.2 se define manométricamente como la presencia de una onda de amplitud y velocidad alta; es decir, con una integral de contractibilidad distal (ICD) superior a 8000 mm Hg/cm/s. Presentamos una serie de cinco pacientes con esófago en martillo neumático que fueron estudiados con manometría esofágica de alta resolución (MAR); recopilamos sus variables clínicas y manométricas. Los casos correspondieron a tres hombres y dos mujeres entre 41 y 73 años de edad. En 3 de ellos se había realizado el diagnóstico de enfermedad por reflujo gastroesofágico, y presentaban síntomas de disfagia, pirosis y regurgitación. El principal hallazgo endoscópico fue la presencia de una hernia hiatal y presbiesófago (2 de 5 pacientes). En todos ellos se realizó MAR que demostró la presencia de una y hasta 4 ondas con ICD superior a 8000 mm Hg/cm/s. Además, la presencia de ondas multipico en 3 de los 5 pacientes, aunque, de acuerdo con la nueva clasificación de Chicago v.3, se requiere la presencia de dos ondas con ICD superior a 8.000 mm Hg/cm/s. Se debe resaltar que aún no se cuenta con equipos disponibles que interpreten a MAR y permitan clasificar los trastornos esofágicos por Chicago v.3, y es por esto que en nuestra unidad de fisiología aún reportamos la MAR con la clasificación previa. Concluimos que el esófago en martillo neumático es una patología con clínica variada que va desde disfagia y dolor torácico hasta síntomas por ERGE, cuyo diagnóstico debe ser confirmado por MAR

Jackhammer esophagus is a peristaltic hypercontractile disorder. According to the second version of the Chicago Classification of esophageal motility, jackhammer esophagus is defined manometrically by distal contractile integrals greater than 8000 mm Hg/cm/s which indicates very high amplitude and velocity. We present a series of five patients with jackhammer esophagus who underwent high-resolution esophageal manometry (HREM) from which clinical and manometric data were collected. There were three men and two women whose ages ranged from 41 to 73. Three of them had been diagnosed with gastroesophageal reflux disease, and showed symptoms of dysphagia, heartburn and regurgitation. The main endoscopic finding was the presence of hiatal hernia and presbyesophagus in two patients. HREM showed waves of up to 4 mm Hg greater than 8000 mm Hg/cm/s. In three of the five patients there were multiple waves. Although, the new third version of the Chicago classification of requires two waves with DCIs over 8000 mm Hg/cm/s to confirm a diagnosis of jackhammer esophagus, it should be noted that we do not yet have available equipment to interpret MAR and allow classifying esophageal disorders by Chicago v.3, and that is why in our physiology unit we still report the MAR with presorting. We conclude that the jackhammer esophagus is a disease with a varied clinical presentation that ranges from dysphagia and chest pain to GERD symptoms. Diagnosis must be confirmed by HREM

Acalasia como trastorno de la motilidad esofágica / Achalasia and esophageal motility disorder

La acalasia es un trastorno esofágico, de tipo motor primario y de etiología desconocida, que fue descubierta por Sir Thomas Williams en 1674. Se presenta por igual en hombres y mujeres, siendo la edad habitual de presentación entre los 25 y 60 años. Fisiopatológicamente, hay un proceso inflamatorio que conlleva a la pérdida de neurotransmisores inhibitorios y a un desbalance entre neuronas inhibitorias y excitatorias. Esto desencadena una aumentada actividad colinérgica, que ocasiona la relajación incompleta del esfínter esofágico inferior (EEI). Clínicamente, el paciente presenta disfagia, regurgitación, pirosis, halitosis, dolor torácico y disfonía. La manometría en alta resolución constituye junto con la anamnesis los métodos diagnósticos de elección, manométricamente se caracteriza por relajación insuficiente del EEI y pérdida de la peristalsis esofágica. Radiográficamente se documenta aperistalsis, dilatación esofágica con apertura mínima del EEI, apariencia en "pico de ave", así como escaso vaciamiento del bario. Endoscópicamente se visualiza dilatación esofágica con retención de saliva, líquido y partículas de alimento no digeridas en ausencia de estenosis de la mucosa o tumores. El tratamiento incluye opciones como fármacos, inyección de toxina botulínica, dilatación neumática, miotomía y esofagectomía.

Achalasia is an esophageal, primary motor disorder of unknown etiology, which was discovered by Sir Thomas Williams in 1674. It occurs equally in men and women, with the usual age of onset between 25 and 60 years. Pathophysiologically, there are an inflammatory process leading to a loss of inhibitory neurotransmitters and an imbalance between inhibitory and excitatory neurons. This triggers an increased cholinergic activity, which causes incomplete relaxation of the lower esophageal sphincter (LES). Clinically, the patient presents dysphagia, regurgitation, heartburn, dyspnea, chest pain and dysphonia. High resolution manometry constitutes together with the anamnesis, the gold standard for diagnosis. Manometry is characterized by insufficient LES relaxation and loss of esophageal peristalsis. Aperistalsis, esophageal dilation with minimal LES opening, "bird-peak" appearance, and poor emptying of barium are radiographically documented. Dilated esophagus with retention of saliva, liquid and undigested food particles in the absence of stenosis or mucosal tumors, are the main findings of the endoscopy. Treatment includes options such as drugs, botulinum toxin injection, pneumatic dilatation, myotomy, and esophagectomy.

Alteraciones motoras esofágicas en pacientes con síndrome de Sjögren: estudio de casos y controles / Esophageal motility disorders in patients with primary Sjogren's syndrome: study of cases and controls

El síndrome de Sjögren primario (SSp), afecta diversos sistemas, como el digestivo; destacando la dificultad deglutoria del bolo alimentario. El objetivo de este estudio es describir la función y motilidad esofágica de pacientes con SSp y compararla con sujetos sanos. Estudio de casos y controles, realizado en Clínica Mayor de Temuco (2004-2009). Se estudiaron pacientes con SSp, con disfagia permanente, sin límite de edad ni sexo (casos); y sujetos asintomáticos digestivos (controles); emparejados por edad y sexo. Se estudiaron con manometría esofágica estacionaria. Se determinó presión de reposo (PR) y longitud (L) del esfínter esofágico inferior (EEI) y superior (EES); amplitud (A) y duración (D) de las ondas peristálticas desencadenadas con degluciones secas y húmedas en los tres tercios del cuerpo esofágico (S, M e I), y aparición de ondas terciarias (OT). Se estimó una muestra 20 casos y 40 controles. Se aplicó estadística descriptiva, Chi2 de Pearson o exacto de Fischer para variables categóricas; y Prueba t para variables continuas. La PREEI fue menor en los casos (11,8±0,7 mmHg vs. 14,8±0,5 mmHg respectivamente). Se verificaron diferencias estadísticamente significativas en la AS, DM, DI y OT tras las degluciones secas; y, en AS, AM, AI, DM, DI y OT, tras las degluciones húmedas. No hubo variaciones en la PREES ni LEES entre casos y controles. Se verificaron alteraciones motoras esofágicas y baja PREEI en pacientes con SSp, respecto de un grupo de controles.

Primary Sjögren's syndrome (PSS), affects various systems such as the digestive; highlighting the difficulty swallowing food bolus. The objective of this study is to describe the function and in patients with esophageal motility PSS compare them to healthy subjects. Case studies and tests conducted at the clinica Mayor Temuco (2004-2009). PSS patients with permanent dysphagia, regardless of age or sex (cases) were studied and digestive asymptomatic subjects (controls); matched for age and sex. We studied these with stationary esophageal manometry. Resting pressure (RP) and length (L) of the lower esophageal sphincter (LES) and upper (UES) was determined; amplitude (A) and duration (D) of the peristaltic waves triggered with dry and wet swallows in the three thirds of the esophageal body (S, M and I), and appearance of tertiary waves (TW). A sample of 20 cases and 40 controls were estimated. Descriptive statistics, Pearson Chi2 or Fisher's exact was applied for categorical variables; and t-test for continuous variables. The PREEI was lower in cases (11.8±0.7 mmHg vs. 14.8±0.5 mmHg respectively). Statistically significant differences in the AS, DM, DI and TW were verified after dry swallows; and in AS, AM, AI, DM, DI and TW after wet swallows. There were no changes in Prees or LEES between cases and controls. Lower esophageal motor disorders was checked in patients with PSS RPEEI, for a control group.

Analysis of upper esophageal sphincter pressure with symptoms and prognosis in 158 patients with achalasia / 中华消化杂志

Objective To investigate upper esophageal sphincter (UES)abnormalities in patients with achalasia (AC),and to analyze the correlation between UES abnormalities and clinical symptoms, treatment efficacy.Methods From February 2012 to December 2014,158 patients with AC and received high resolution manometry (HRM)examination were retrospectivly analyzed.According to whether with UES abnormalities,patients were divided into UES normal group and UES abnormal group.Patients of UES abnormal group were sub-divided into UES hypotensive group (UES resting pressure104 mmHg)and impaired relaxation group (residual pressure>12 mmHg).Analysis of Variance,Kruskal-Wallis H test and Chi square test were performed to compare the clinical data and dynamic characteristics of the patients in each group. Results A total of 74 (46.8%)AC patients had UES abnormalities,the majority of whom were impaired relaxation (35 cases,47.3%).The age of patients in hypotensive group ((60.6 ± 10.1 )years)was significantly older than that of hypertensive group ((43.9 ±11 .1 )years)and impaired relaxation group ((46.8±16.3)years),and the disease course (10 years,4 to 30 years)was obviously longer than that of hypertensive group (6 years,1 to 10 years)and impaired relaxation group (8 years,3 to 15 years),and the differences were statistically significant (F = 7.983,H = 13.816,both P 0.05 ).The results of AC subtyping indicated that type Ⅱ AC accounted 55 .7% (88/158).Type Ⅱ AC cases number of UES normal group and abnormal group was 46 and 42 cases,both was majority (54.8% and 56.8%).Among these patients,123 patients finally received peroral endoscopic myotomy (POEM),47.2%(58/123 )of whom had abnormal UES.More than 85 % patients were satisfied at one month after the operation.And Eckardt scores significantly decreased.There was no significant difference in treatment efficacy between the two groups.Conclusions Most AC patients are with UES abnormality,and impaired relaxation is more common.There is no correlation between UES abnormalities and major symptoms.There is no predictive role of UES abnormalities in treatment efficacy of POEM in AC patients.

Study of esophageal motility in the cases with myasthenia gravis / 中华胸心血管外科杂志

Objective To study the features of esophageal motility in the cases with myasthenia gravis(MG).Methods 15 healthy controls and 45 patients with MG were tested by using a low-compliance four-lumen hydraulic infusion system,respectively.Focused on the following parameters:PP,UESP,UEP,MEP and MERP.Results There were significant differences of the parameters in between MG cases and healthy controls PP (73.24 ± 31.40) mmHg (1 mmHg =0.133 kPa) vs.(103.78±29.47) mmHg,P=0.002;UESP(41.75 ±21.04) mmHg vs.(60.59 ±17.97) mmHg,P=0.003;UEP (56.63 ±30.26) mmHg vs.(78.98 ±30.14) mmHg,P =0.016;MEP(53.96 ±23.25) mmHg vs.(75.11 ±23.75) mmHg(P =0.004).However,MERP of MG cases or healthy controls seemed to be similar[(-7.76 ± 5.94) mmHg vs.(-7.58 ± 5.76) mmHg,P =0.91).Additionally,the above-mentioned parameters in the cases with generalized myasthenia gravis or dysphagia were significantly different compared with other subtypes or healthy controls (P ＜ 0.01).However,there were no significant differences of the parameters in between ocular MG and healthy controls,or in between MG with and without thymoma.Conclusion The upper and middle part of esophageal motility dysfunction is very common in MG cases,especially in those with dysphagia or generalized MG,characterizing by the declined pressure.Manometry in MG cases can help us classify the subtypes of MG and verify their esophageal motility functions.
