Impacto de la cardiomiotomía laparoscópica de Heller en la función del esfínter esofágico inferior y el diámetro del esófago / Impact of laparoscopic Heller cardiomyotomy on lower esophageal sphincter function and esophageal diameter

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

Prevalence and predictors of functional evacuation disorder in patients with chronic constipation

Background: Functional evacuation disorder (FED) is the second most common cause of functional constipation (FC) after constipation-predominant irritable bowel syndrome. However, the data on FED is relatively scanty in our region. Hence, the present study was performed to evaluate the demographics of FED and to find out the predictors of FED in patients with chronic constipation. Methods: A total of 134 patients with chronic constipation diagnosed according to the Rome IV criteria who were referred for high-resolution anorectal manometry (HRAM) were retrospectively enrolled in the present study. All FC patients who underwent HRAM were asked to fill a questionnaire and underwent anorectal manometry and were submitted to the balloon expulsion test (BET). Results: The mean age of patients was 43.09 ± 9.32 years old, with a total of 76 (54%) males. The most common symptom was straining during defecation (87%) followed by incomplete evacuation (86%). The prevalence of FED, diagnosed by HRAM and by the BET was 39%. Patients with FED had a significantly higher percentage of straining and sensation of anorectal blockade compared with those without FED (96 versus 82%; p < 0.01; 81 versus 44%; p < 0.001, respectively). On the multivariate regression analysis, straining > 30 minutes (odds ratio [OR] = 3.63; p = 0.03), maximum squeeze pressure (OR = 1.05; p < 0.001), and balloon volume at maximal sensation (OR = 1.06; p < 0.001) were found to be significant independent predictors of FED. Conclusion: Prolonged straining and sensation of anorectal blockade were significant indicators of FED in patients with chronic constipation. (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.

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)

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.

Distúrbios funcionais esofágicos na avaliação pré-operatória de cirurgia bariátrica / Esophageal functional disorders in the pre-operatory evaluation of bariatric surgery

ABSTRACT BACKGROUND: Obesity is an independent risk factor for esophageal symptoms, gastroesophageal reflux disease (GERD), and motor abnormalities. When contemplating bariatric surgery, patients with obesity type III undergo esophagogastroduodenoscopy (EGD) and also esophageal manometry (EMN), and prolonged pHmetry (PHM) as part of their pre-operative evaluation. OBJECTIVE: Description of endoscopy, manometry and pHmetry findings in patients with obesity type III preparing for bariatric surgery, and correlation of these findings with the presence of typical GERD symptoms. METHODS: Retrospective study in which clinical symptoms of GERD were assessed, focusing on the presence of heartburn and regurgitation. All patients underwent EMN, PHM and most of them EGD. RESULTS: 114 patients (93 females-81%), average age 36 years old, average BMI of 45.3, were studied. Typical GERD symptoms were referred by 43 (38%) patients while 71 (62%) were asymptomatic. Eighty two patients (72% of total) underwent EGD and 36 (42%) evidenced esophageal abnormalities. Among the abnormal findings, hiatal hernia was seen in 36%, erosive esophagitis (EE) in 36%, and HH+EE in 28%. An abnormal EMN was recorded in 51/114 patients (45%). The main abnormality was a hypotensive lower esophageal sphincter (LES) in 32%, followed by ineffective esophageal motility in 25%, nutcracker esophagus in 19%, IEM + hypotensive LES in 10%, intra-thoracic LES (6%), hypertensive LES (4%), aperistalsis (2%) and achalasia (2%). Among the 43 symptomatic patients, 23 (53%) had abnormal EMN and 31/71 asymptomatic cases (44%) also presented this finding (P=0.30). PHM showed abnormal reflux in 60/114 patients (53%), with a predominance of bi-positional reflux (42%), followed by supine reflux (33%) and upright reflux (25%). Abnormal PHM was found in 26/43 symptomatic cases (60%) and also among 34/71 asymptomatic cases (48%) (P=0.19). CONCLUSION: Manometric abnormalities were common in obesity type III patients, the most frequent being hypotensive LES, followed by IEM. Most patients were asymptomatic. There was no correlation between the finding of motor abnormalities and the presence of symptoms. More than half the patients had abnormal reflux at PHM. We found no significant correlation between abnormal reflux and the presence of symptoms.

RESUMO CONTEXTO: A obesidade é fator de risco independente para sintomas esofagianos, doença do refluxo gastroesofágico (DRGE) e alterações motoras. Pacientes com obesidade tipo III, candidatos à cirurgia bariátrica foram submetidos a endoscopia digestiva alta (EDA) e também realizaram esofagomanometria (EMN) e pHmetria prolongada (PHM) como parte da avaliação pré-operatória. OBJETIVO: Em um grupo de pacientes com obesidade tipo III em pré-operatório de cirurgia bariátrica, descrever os achados endoscópicos, manométricos e pHmétricos, correlacionando-os com a presença de sintomas típicos de DRGE.

RESULTADOS: Foram incluídos 114 pacientes, 93 (81%) do sexo feminino, média de idade de 36 anos e IMC médio de 45,3. Sintomas típicos de refluxo foram referidos por 43 (38%) pacientes e 71 (62%) eram assintomáticos. EDA foi realizada por 82 (72%) pacientes, havendo anormalidades esofagianas em 36 (42%). Entre os anormais, havia hérnia hiatal (HH) em 36%, esofagite erosiva (EE) em 36% e HH + EE em 28%. A EMN foi anormal em 51/114 (45%). Entre os anormais, predominou o esfíncter esofagiano inferior (EEI) hipotenso em 32%, seguido por motilidade esofagiana ineficaz (MEI) em 25%, esôfago em quebra-nozes (19%), EEI hipotenso + MEI (10%), EEI intra-torácico (6%), EEI hipertenso (4%), aperistalse (2%) e acalasia (2%). Dentre os 43 sintomáticos, 23 (53%) apresentavam EMN anormal, sendo que em 31 dos 71 (44%) assintomáticos a EMN também era anormal (P=0,30). A PHM revelou refluxo anormal em 60 (53%) pacientes. Predominou o refluxo anormal biposicional (42%) seguido do refluxo supino (33%) e refluxo ereto (25%). Dentre os 43 pacientes sintomáticos, 26 (60%) apresentavam PHM anormal, sendo que em 34 dos 71 assintomáticos a PHM também era anormal (48%) - P=0,19. CONCLUSÃO: Alterações manométricas foram comuns em obesidade tipo III, sendo as mais frequentes o EEI hipotenso, seguida de motilidade ineficaz. A maioria dos pacientes era assintomática. Mais da metade dos pacientes apresentou refluxo anormal à PHM. Não houve diferença significativa entre o achado de refluxo anormal e a presença de sintomas. Não houve relação entre o achado de alterações motoras e a presença de sintomas.

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.

Carotid Intima and Media Thickness Correlation with Central Blood Pressure Measurements by Tonometric and Oscillometric Methods: A Proof of Concept

Abstract Background The early detection of vascular damage in subclinical stages of hypertensive disease may be the key point in the prevention of cardiovascular outcomes. Objectives to correlate parameters of structural vascular damage (measurement of the carotid intima-media thickness) with parameters of functional vascular damage (central hemodynamic measurements) in pre-hypertensive and hypertensive patients taking up to two classes of anti-hypertensive drugs. Methods This was a cross-sectional descriptive study conducted with a convenience sample of patients attending the Liga de Hipertensão Arterial , a multidisciplinary program for the diagnosis and treatment of systemic hypertension, of the Federal university of Goias. Patients with arrythmia, diabetes, previous cardiovascular or cerebrovascular diseases, and end-stage diseases were excluded. Carotid Doppler test, measurements of peripheral and central blood pressure by applanation tonometry (Sphygmocor®) and oscillometry (Mobil-O-Graph®) were performed. The t-test was used for comparisons and the Pearson correlation test for correlations, considering a p<0.05 statistically significant. Results twenty patients (12 women) were evaluated, mean age 53.8 ± 14.3 years. Higher values of central pulse pressure (42.9±13.9 vs. 34.7±9.6, p=0.01) and pulse wave velocity (PWV) (9.0±1.9 vs. 7.9±1.5, p=0.01) were obtained by applanation tonometry compared with oscillometry. No difference between the methods was observed for the other measures. A significant correlation was found between carotid artery intima-media thickness (CA-IMT) and PWV (r=0.659; p=0.002) by the oscillometric test, but not with applanation tonometry. No correlation was found between central hemodynamic variables and the presence of carotid artery plaques. Conclusion PWV, estimated by oscillometry, was the only central hemodynamic parameter that correlated significantly with CA-IMT in pre-hypertensive and hypertensive patients at low cardiovascular risk.

Importance of esophageal pH monitoring and manometry in indicating surgical treatment of gastroesophageal reflux disease

SUMMARY OBJECTIVE: To demonstrate the need of performing esophageal pH monitoring and manometry in patients with clinical suspicion of Gastroesophageal reflux disease, as more accurate and practical complementary exams in the indication of surgical treatment. METHODS: A systematic review was carried out in the PubMed/Medline database, based on the recommendations of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, selecting studies in humans, published in Portuguese, Spanish, and English, from January 1, 2009 to August 5, 2020. The following descriptors were used: "reflux gastroesophageal" AND "surgery" AND "surgical treatment" AND "esophageal manometry" OR "pH monitoring". After that, retrospective or prospective observational studies with a sample of less than 100 individuals, or with limited access, reports or case series, review articles, letters, comments, or book chapters were excluded. To facilitate the application of the exclusion criteria, the Rayyan management base was used. RESULTS: Out of the 676 studies found, 19 valid and eligible studies were selected to make inferences. CONCLUSIONS: Based on the best evidence, currently, considering national particularities, performing a 24-hour esophageal pH monitoring and esophageal manometry for all patients undergoing anti-reflux surgery.

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).

Danos anatômicos ao esfíncter esofágico inferior após gastrectomia subtotal / Anatomic damage of the lower esophageal sphincter after subtotal gastrectomy

RESUMO - RACIONAL: Disfunção do esfíncter esofágico inferior (EEI), doença do refluxo gastroesofágico e esofagite erosiva em pacientes submetidos à gastrectomia subtotal são ocorrências comumente reconhecidas, mas até agora as causas permanecem obscuras. OBJETIVO: A hipótese deste estudo é que a gastrectomia subtotal provoque alterações na pressão de repouso do EEI e na sua competência, devido ao dano anatômico desta, visto que as fibras oblíquas "Sling", um dos componentes musculares do EEI, são seccionadas durante este procedimento cirúrgico. MÉTODOS: Sete cães adultos sem raça definida (18-30 kg) foram anestesiados e submetidos à transecção do estômago proximal. Em seguida, o remanescente gástrico proximal foi fechado por sutura. No intraoperatório, manometria lenta foi realizada em cada cão, em condições basais (com estômago intacto) e no remanescente gástrico proximal fechado. A média dessas medidas é apresentada, com cada cão servindo como seu próprio controle. RESULTADOS: A pressão média do EEI medida no remanescente gástrico proximal, em comparação com a pressão do EEI no estômago intacto, foi diminuída em cinco cães, aumentada em um cão e sem alterações no outro cão. CONCLUSÃO: A secção transversa superior do estômago e o fechamento do remanescente do estômago por sutura provocam alterações na pressão do EEI. Sugerimos que essas mudanças na pressão do EEI são secundárias à secção das fibras oblíquas "Sling" do esfíncter, um de seus componentes musculares. A sutura e o fechamento do remanescente gástrico proximal, reancora essas fibras com mais, menos ou a mesma tensão, modificando ou não a pressão do EEI.

ABSTRACT - BACKGROUND: Dysfunction of the lower esophageal sphincter (LES), gastroesophageal reflux disease, and erosive esophagitis in patients undergoing subtotal gastrectomy are commonly recognized occurrences, but until now the causes remain unclear. AIM: The hypothesis of this study is that subtotal gastrectomy provokes changes on the LES resting pressure and its competence, due to the anatomical damage of it, given that the oblique "Sling" fibers, one of the muscular components of the LES, are transected during this surgical procedure. METHODS: Seven adult mongrel dogs (18-30 kg) were anesthetized and admitted for transection of the proximal stomach. Later, the proximal gastric remnant was closed by a suture. Intraoperatively, slow pull-through LES manometries were performed on each dog, under basal conditions (with the intact stomach), and in the closed proximal gastric remnant. The mean of these measurements is presented, with each dog serving as its control. RESULTS: The mean LES pressure (LESP) measured in the proximal gastric remnant, compared with the LESP in the intact stomach, was decreased in five dogs, increased in one dog, and remained unchanged in other dogs. CONCLUSION: The upper transverse transection of the stomach and closing the stomach remnant by suture provoke changes in the LESP. We suggested that these changes in the LESP are secondary to transecting the oblique "Sling" fibers of the LES, one of its muscular components. The suture and closing of the proximal gastric remnant reanchor these fibers with more, less, or the same tension, whether or not modifying the LESP.

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.

The real impact of colonic transit time and anorectal manometry in the diagnosis of adult patients with chronic constipation / O real impacto do tempo de trânsito cólico e da manometria anorretal no diagnóstico de pacientes adultos com constipação crônica

Abstract Introduction: Anorectal physiology tests are indicated for patients who have refractory symptoms of constipation, but the best sequence of investigation remains controversial. Objective: To evaluate the influence of colonic transit time and anorectal manometry in the diagnosis of chronic constipation in adults. Method: This was a study of adult patients with constipation at a private clinic in a city in southern Brazil, from January 1, 2009 to December 31, 2018. Those who showed warning signs were referred for colonoscopy and those with any anatomical alterations were excluded. The patients received 10 g of psyllium and those who remained symptomatic after three weeks were referred for functional assessment with colonic transit time (CTT). Those who presented outlet obstruction in the colonic transit time were referred to anorectal manometry. Results: Of the 889 adult patients surveyed, 227 were included. Of the 216 who completed the study, 167 responded to primary treatment. Forty-nine underwent CTT. In these, 16 had normal colonic transit time and 33 were altered. In those with altered colonic transit time, eight had a pattern of colonic inertia and 25 had an obstruction pattern. The 25 patients with an outlet obstruction pattern underwent anorectal manometry. Eighteen had signs of paradoxical contracture of the puborectal muscle (PPRC) and seven did not. Conclusion: This study concluded that anorectal physiology exams contribute to the diagnosis of constipation, often changing the behavior. These exams should be performed whenever the patient does not respond to hygienic changes and fiber replacement.

Resumo Introdução: Os exames de fisiologia anorretal estão indicados nos pacientes que mantém sintomas refratários de constipação, porém uma sequência desejada de investigação permanece contraditória. Objetivo: Avaliar a influência do tempo de trânsito colônico e da manometria anorretal no diagnóstico da constipação crônica de adultos. Método: Estudamos os pacientes adultos de uma clínica privada em uma cidade do sul do Brasil, no período de 01 de Janeiro de 2009 a 31 de Dezembro de 2018 apresentando constipação. Aqueles que apresentassem sinais de alerta, eram encaminhados a colonoscopia e com qualquer alteração anatômica eram excluídos. Foram prescritos 10 g de Psyllium e aqueles que permaneceram sintomáticos após três semanas foram encaminhados à avaliação funcional com tempo de trânsito colônico (TTC). Os que apresentavam obstrução de saída ao tempo de trânsito colônico foram encaminhados a manometria anorretal. Resultados: Dos 889 pacientes adultos levantados, 227 foram incluídos. Dos 216 que concluíram o estudo, 167 responderam ao tratamento primário. Quarenta e nove realizaram TTC. Nestes, 16 tiveram tempo de trânsito colônico normal e 33 alterado. Naqueles com tempo de trânsito colônico alterado: oito tinham padrão de inércia colônica e 25, padrão de obstrução de saída. Os 25 pacientes com padrão de obstrução de saída foram submetidos à manometria anorretal. Dezoito tinham sinais de Contratura Paradoxal do músculo Puborretal (CPPR) e sete não. Conclusão: Concluímos que os exames de fisiologia anorretal contribuem para o diagnóstico da constipação, muitas vezes alterando a conduta. Estes exames devem ser realizados sempre que o paciente não responder as alterações higienodietéticas e a reposição de fibras.

Principais achados manométricos e potencial da fisioterapia anorretal no tratamento de pacientes com distúrbios evacuatórios / Main manometric findings and potential for anorectal physical therapy in the treatment of patients with evacuation disorders

ABSTRACT BACKGROUND: Evacuation disorders are prevalent in the adult population, and a significant portion of cases may originate from pelvic floor muscle dysfunctions. Anorectal manometry (ARM) is an important diagnostic tool and can guide conservative treatment. OBJECTIVE: To evaluate the prevalence of pelvic dysfunction in patients with evacuation disorders through clinical and manometric findings and to evaluate, using the same findings, whether there are published protocols that could be guided by anorectal manometry. METHODS: A retrospective analysis of a prospective database of 278 anorectal manometries performed for the investigation of evacuation disorders in patients seen at the anorectal physiology outpatient clinic of Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto between January 2015 to June 2019 was conducted. The following parameters were calculated: resting pressure (RP), squeeze pressure (SP), high-pressure zone (HPZ), rectal sensitivity (RS) and rectal capacity (RC). The pressure measurements and manometric plots were reviewed to determine the diagnosis and to propose potential pelvic physical therapy procedures. Analysis of variance (ANOVA) and Fisher's exact test were used to compare the continuous variables and to evaluate the equality of variances between groups of patients with fecal incontinence (FI) and chronic constipation (CC). Results with a significance level lower than 0.05 (P-value <0.05) were considered statistically significant. Statistical analysis was performed using IBM® SPSS® Statistics version 20. RESULTS: The mean age of the sample was 45±22 years, with a predominance of females (64.4%) and economically inactive (72.7%) patients. The indications for exam performance were FI (65.8%) and CC (34.2%). Patients with FI had lower RP (41.9 mmHg x 67.6 mmHg; P<0.001), SP (85.4 mmHg x 116.0 mmHg; P<0.001), HPZ (1.49 cm x 2.42 cm; P<0.001), RS (57.9 mL x 71.5 mL; P=0.044) and RC (146.2 mL x 195.5 mL; P<0.001) compared to those of patients with CC. For patients with FI, the main diagnosis was the absence of a functional anal canal (49.7%). For patients with CC, the main diagnosis was outflow tract obstruction (54.7%). For patients with FI, the main protocol involved a combination of anorectal biofeedback (aBF) with tibial nerve stimulation (TNS) (57.9%). For patients with CC, the most indicated protocol was aBF combined with TNS and rectal balloon training (RBT) (54.7%). CONCLUSION: There was a high prevalence of pelvic floor changes in patients with evacuation disorders. There was a high potential for performing pelvic floor physical therapy based on the clinical and manometric findings.

RESUMO CONTEXTO: Os distúrbios evacuatórios são prevalentes na população adulta e uma parcela significativa dos casos pode ter origem a partir de disfunções da musculatura do assoalho pélvico. A manometria anorretal (MAR) é importante ferramenta diagnóstica e pode guiar o tratamento conservador. OBJETIVO: Avaliar a prevalência de disfunção pélvica em pacientes com distúrbios de evacuação por meio de achados clínicos e manométricos e avaliar, usando os mesmos achados, se existem protocolos publicados que possam ser guiados pela MAR. MÉTODOS: Conduziu-se uma análise retrospectiva de um banco de dados prospectivo de 278 manometrias anorretais realizadas para investigação de distúrbios evacuatórios em pacientes do ambulatório de fisiologia anorretal do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, de janeiro de 2015 a junho de 2019. Os seguintes parâmetros foram calculados: pressão de repouso (RP), pressão de contração voluntária (PVC), canal anal funcional (CAF), sensibilidade retal (SR) e capacidade retal (CR). As medidas pressóricas e os gráficos manométricos foram revisados para elaboração do diagnóstico e para a proposição dos potenciais procedimentos de fisioterapia pélvica. Para comparação das variáveis contínuas e avaliação da igualdade entre variâncias, utilizou-se a análise de variância (ANOVA) e o teste exato de Fisher, entre os grupos de pacientes com incontinência fecal (IF) e constipação crônica (CC). Resultados com nível de significância menor que 0,05 (P-valor <0,05) foram considerados estatisticamente relevantes. Para análise estatística utilizou-se o programa IBM® SPSS® Statistics, versão 20. RESULTADOS: A idade média dos pacientes foi de 45±22 anos de idade, com predomínio do sexo feminino (64,4%) e economicamente inativo (72,7%). As indicações para a realização do exame foram IF (65,8%) e CC (34,2%). Pacientes com IF apresentaram menores valores de PR (41,9 mmHg x 67,6 mmHg; P<0,001), PCV (85,4 mmHg x 116,0 mmHg; P<0,001) CAF (1,49 cm x 2,42 cm; P<0,001), SR (57,9 mL x 71,5 mL; P=0,044) e CR (146,2 mL x 195,5 mL; P<0,001), quando comparados aos pacientes com CC. Nos pacientes com IF, o principal diagnóstico foi de ausência de canal anal funcional (49,7%). Em pacientes com CI, o principal diagnóstico foi de obstrução da via de saída (54,7%). Para pacientes com IF, o principal protocolo foi a associação do biofeedback anorretal (BFa) com estimulação do nervo tibial (ENT) (57,9%). Já nos pacientes com CC, o protocolo mais indicado foi o de BFa associado à ENT e treinamento com balão retal (54,7%). CONCLUSÃO: Observou-se elevada prevalência de alterações no assoalho pélvico de pacientes com distúrbios evacuatórios. Verificou-se elevado potencial para realização de fisioterapia do assoalho pélvico com base nos achados clínicos e manométricos.

A hiperemia reativa correlaciona-se com presença de sepse e degradação de glicocálix na unidade de terapia intensiva: um estudo de coorte prospectiva / Reactive hyperemia correlates with the presence of sepsis and glycocalyx degradation in the intensive care unit: a prospective cohort study

RESUMO Objetivo: Investigar se a hiperemia reativa correlaciona-se com marcadores de disfunção endotelial e pode ser utilizada para identificar sepse na doença crítica. Métodos: Trata-se de estudo prospectivo em uma coorte de pacientes críticos. A disfunção endotelial foi avaliada quando da admissão, por meio da quantificação de hiperemia por tonometria arterial periférica e níveis plasmáticos de endotelina 1, E-selectina solúvel, endocana e sindecano 1. Os pacientes sépticos foram comparados com pacientes sem evidência de infecção. Resultados: Cinquenta e oito pacientes sépticos foram comparados com 28 controle. O logaritmo natural da tonometria arterial periférica teve correlação negativa com comorbidades cardiovasculares, severidade da doença e níveis plasmáticos de E-selectina solúvel (p = 0,024) e sindecano 1 (p < 0,001). O logaritmo natural da tonometria arterial periférica foi mais baixo nos pacientes sépticos quando comparado com os de pacientes controle (0,53 ± 0,48 versus 0,69 ± 0,42, respectivamente) e, quando ajustado à idade, o modelo multivariado predisse que cada 0,1 de diminuição em unidades de logaritmo natural da tonometria arterial periférica levou a aumento de 14,6% na probabilidade de infecção. Conclusão: A hiperemia reativa avaliada por tonometria arterial periférica tem estreita relação com E-selectina solúvel e sindecano 1, o que sugere associação entre ativação endotelial, degradação de glicocálix e reatividade vascular. A hiperemia reativa por tonometria arterial periférica parece estar comprometida em pacientes críticos, especialmente os com sepse.

Abstract Objective: To investigate whether reactive hyperemia measured by peripheral arterial tonometry correlates with markers of endothelial dysfunction and may be used to identify sepsis in critical illness. Methods: A prospective study was performed using a cohort of critically ill patients. Endothelial dysfunction was assessed on admission by quantifying reactive hyperemia-peripheral arterial tonometry and plasma levels of endothelin-1, soluble E-selectin, endocan and syndecan-1. Septic patients were compared to patients without evidence of infection. Results: Fifty-eight septic patients were compared to 28 controls. The natural logarithm of reactive hyperemia-peripheral arterial tonometry was negatively correlated with cardiovascular comorbidities, disease severity and plasma levels of soluble E-selectin (p = 0.024) and syndecan-1 (p < 0.001). The natural logarithm of reactive hyperemia-peripheral arterial tonometry was lower in septic patients than in controls (0.53 ± 0.48 versus 0.69 ± 0.42, respectively). When adjusted for age, the multivariable model predicted that each 0.1-unit decrease in natural logarithm of reactive hyperemia-peripheral arterial tonometry increased the odds for infection by 14.6%. m. Conclusion: Reactive hyperemia-peripheral arterial tonometry is closely related to soluble E-selectin and syndecan-1, suggesting an association between endothelial activation, glycocalyx degradation and vascular reactivity. Reactive hyperemia-peripheral arterial tonometry appears to be compromised in critically ill patients, especially those with sepsis.

Clinical and physiological efficacy of the application of autologous fat with platelet rich plasma in treating faecal incontinence / Eficácia clínica e fisiológica da aplicação de gordura autóloga com plasma rico em plaquetas no tratamento da incontinência fecal

Abstract Purpose: Faecal incontinence (FI) is a frequent condition that can occur due to different causes; with negative impact on self-esteem and quality of life, secondary morbidity, disability and significant costs. For its treatment there is a wide range of options, being medical treatment, hygienic dietary modifications and biofeedback, the first line of treatment; reserving surgery for patients who do not respond or with severe FI; this with variable success rates and high cost. This study has the primary aim to assess the efficacy and describe the Technique of Application of Autologous Fat with Platelet Rich Plasma (AFPRiP) in patients with faecal incontinence as well as secondary endpoints of quality of life, manometric and ultrasound evaluation, safety of implantation, and complications.

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)
