Tratamiento endoscópico para el reflujo gastroesofágico / Endoscopic treatment of gastroesophageal reflux

Resumen Durante las últimas 2 décadas se han desarrollado una serie de nuevos tratamientos endoscópicos para el tratamiento de la enfermedad por reflujo gastroesofágico (ERGE) como alternativas al tratamiento médico o funduplicatura quirúrgica. Estos dispositivos incluyen aplicación de tratamiento por radiofrecuencia (Stretta), plicatura endoscópica (EndoCinch, Plicator, Esophyx, MUSE) e inyección o implantación de biomateriales (Enteryx, Gatekeeper, Plexiglas, Duragel). Su objetivo es el alivio de los síntomas creando una barrera anatómica antirreflujo. En esta revisión del tema consideramos artículos indexados en Pubmed, Medline y Scielo en los últimos 10 años revisando un total de 55 trabajos. Evaluamos críticamente los resultados reportados, faltan datos a largo plazo superiores a 10 años. Estos procedimientos reducen el uso de inhibidores de la bomba de protones en cerca del 50%. Evaluaciones subjetivas reportan mejoría de la calidad de vida y satisfacción del paciente. Sin embargo, la evaluación objetiva con endoscopia, manometría, radiología y pHmetría son escasos y si los hay, no muestran cambios significativos. No existe evidencia convincente para adoptar estos métodos como tratamiento definitivo y, por lo tanto, la fundoplicatura por vía laparoscópica sigue siendo el estándar de oro para el tratamiento de la enfermedad por reflujo gastroesofágico.

During the last 2 decades, new endoscopic treatments have been developed for the treatment of gastroesophageal reflux disease (GERD) as alternatives to medical treatment or surgical fundoplication. These devices include application of radiofrequency treatment (Stretta), endoscopic plication (EndoCinch, Plicator, Esophyx, MUSE) and injection or implantation of biomaterials (Enteryx, Gatekeeper, Plexiglas, Duragel). Its objective is the relief of symptoms by creating an anatomical anti-reflux barrier. In this review, we consider articles indexed in Pubmed, Medline and Scielo in the last 10 years, reviewing a total of 55 papers, we analyse critically the reported results, although long-term data greater than 5 or 7 years are lacking. These procedures reduce the use of proton pump inhibitors by about 50%. Subjective evaluations report improvement in quality of life and patient satisfaction. However, objective evaluation with endoscopy, manometry, radiology and pHmetry are scarce and if there are, they do not show significant changes. There is no convincing evidence to adopt these methods as definitive treatment. Therefore, laparoscopic fundoplication is the gold standard for the treatment of gastroesophageal reflux disease.

Comparison between herbs used for the treatment of gastroesophageal reflux diseases(GERD)

Background:An abnormality that causes reflux is termed as Gastroesophageal reflux disease (GERD), which is symptomatic by nature and adds to the long-term effects.Objective:The aim of this study is to observe and monitor the effects of a herbal ttratment of GERD with SiniZuojin Decoction (SNZID)and to assess its mediation impacts regarding the use of the medication in patients with Gastrointestinal EBB ailment.Materials and Methods:The cohort research methodology was used inthe study.The research included 2581 individual patients who were older than 18 years of age and were suffering from Gastrointestinal ebbailment. The patients were selected from various government herbal clinics in eastern China, including the states of Anhui, Fujian, Jiangsu, Jiangxi, Shandong, and Zhejiangover, from 2008 to 2018. Results:The study was conducted with a total of 2581 patients. The thorough assessment indicated that Sini Zuojin Decoction (SZD)notwithstanding standard stomach remedies pack was more effective than the traditionalist stomach suppositories bundle (RR=1.34, with CI=95% [1.47, 1.38], and P-value = 0.008); Test packs including SZD was essentially better contrasted with traditional stomach medicines(TSM)gearshifts in developing dyspepsia, substernal chest plague, decreasing regurgitation, and vomiting (P < 0.0002); SNZJD plus traditional stomach medicines(SPTSM)could by and large lessen full-scale sign scores with liberal ampleness (P < 0.00002). The replication degree and antagonistic effects regarding Sacroiliac Joint Dysfunction(SJD)treatment were basic. As confirmed through the TSA regarding thorough assessment, the results were significant, yet repeat security consequences were uncertain. As shown by the computation of the Grading of Recommendations Assessment, Development and Evaluation(GRADE)strategy, the idea regarding verification was minimal. Moreover, Schizoaffective disorder(SZD)may treat Gastrointestinal ebb ailment by presenting the onsetof the infection and controlling factors that may contribute to Gastrointestinal ebb ailments.Conclusion:The research evaluated the efficiency of Sini Zuojin Decoction in treating patients suffering from Gastrointestinal Ebb Ailments.

History and present situation of seromuscular flap anastomosis in proximal gastrectomy / 中华胃肠外科杂志

With the increasing detection rate of early upper gastric cancer and adenocarcinoma of esophagogastric junction, the safety of proximal gastrectomy with clear indications has been verified, and function-preserving proximal gastrectomy has been widely used. However, proximal gastrectomy destructs the normal anatomical structure of esophagogastric junction, resulting in severe postoperative gastroesophageal reflux symptoms and seriously affecting the quality of life. Among various anti-reflux surgery methods, reconstruction of "cardiac valve" has always been the focus of relevant scholars because its similarity with the mechanism of normal anti-reflux. After years of development, evolution and optimization, the designed seromuscular flap anastomosis includes tunnel muscle flap anastomosis, Hatafuku valvuloplasty, single muscle flap anastomosis and double muscle flap anastomosis. The double muscle flap anastomosis has become a research hotspot because it shows good anti-reflux effect in clinical application. This paper reviews the history, research status and hot issues of seromuscular flap anastomosis of esophageal remnant stomach at home and abroad.

Functional outcomes of 100 patients with adenocarcinoma of the esophagogastric junction undergoing Cheng's GIRAFFE(®) reconstruction after proximal gastrectomy / 中华胃肠外科杂志

Objective: To investigate the functional outcomes and postoperative complications of Cheng's GIRAFFE reconstruction after proximal gastrectomy. Methods: A descriptive case series study was conducted. Clinical data of 100 patients with adenocarcinoma of the esophagogastric junction who underwent Cheng's GIRAFFE reconstruction after proximal gastrectomy in Cancer Hospital of University of Chinese Academy of Sciences (64 cases), Zhejiang Provincial Hospital of Chinese Medicine (24 cases), Lishui Central Hospital (10 cases), Huzhou Central Hospital (1 case) and Ningbo Lihuili Hospital (1 case) from September 2017 to June 2021 were retrospectively analyzed. Of 100 patients, 64 were males and 36 were females; the mean age was (61.3 ± 11.1) years and the BMI was (22.7±11.1) kg/m(2). For TNM stage, 68 patients were stage IA, 24 were stage IIA and 8 were stage IIB. Postoperative functional results and postoperative complications of radical gastrectomy with Giraffe reconstruction were analyzed and summarized. Gastroesophageal reflux disease questionnaire (RDQ) score and postoperative endoscopy were used to evaluate the occurrence of reflux esophagitis and its grade (grade N, grade A, grade B, grade C, and grade D from mild to severe reflux). The continuous data conforming to normal distribution were expressed as (mean ± standard deviation), and those with skewed distribution were presented as median (Q1, Q3). Results: All the 100 patients successfully completed R0 resection, including 77 patients undergoing laparoscopic surgery and 23 patients undergoing laparotomy. The Giraffe anastomosis time was (38.6±14.0) min; the blood loss was (73.0±18.4) ml; the postoperative hospital stay was 9.5 (8.2, 13.0) d; the hospitalization cost was (6.0±0.3) ten thousand yuan. Fourteen cases developed perioperative complications (14.0%), including 7 cases of pleural effusion or pneumonia, 3 cases of anastomotic leakage, 2 cases of gastric emptying disorder, 1 case of gastrointestinal hemorrhage and 1 case of anastomotic stenosis, who were all improved and discharged after symptomatic management. Patients were followed up for (33.3±1.6) months. Eight patients were found to have reflux symptoms by RDQ scale six months after surgery, and 11 patients (11/100,11.0%) were found to have reflux esophagitis by gastroscopy, including 6 in grade A, 3 in grade B, and 2 in grade C. All the patients could control their reflux symptoms with behavioral guidance or oral PPIs. Conclusion: Cheng's GIRAFFE reconstruction has good anti-reflux efficacy and gastric emptying function; it can be one of the choices of reconstruction methods after proximal gastrectomy.

Prevalence, risk factors and parental perceptions of gastroesophageal reflux disease in Asian infants in Singapore

INTRODUCTION@#Infant gastroesophageal reflux disease (GERD) is a significant cause of concern to parents. This study seeks to describe GERD prevalence in infants, evaluate possible risk factors and assess common beliefs influencing management of GERD among Asian parents.@*METHODS@#Mother-infant dyads in the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO) cohort were prospectively followed from preconception to 12 months post-delivery. GERD diagnosis was ascertained through the revised Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R) administered at 4 time points during infancy. Data on parental perceptions and lifestyle modifications were also collected.@*RESULTS@#The prevalence of infant GERD peaked at 26.5% at age 6 weeks, decreasing to 1.1% by 12 months. Infants exclusively breastfed at 3 weeks of life had reduced odds of GERD by 1 year (adjusted odds ratio 0.43, 95% confidence interval 0.19-0.97, P=0.04). Elimination of "cold or heaty food" and "gas producing" vegetables, massaging the infant's abdomen and application of medicated oil to the infant's abdomen were quoted as major lifestyle modifications in response to GERD symptoms.@*CONCLUSION@#Prevalence of GERD in infants is highest in the first 3 months of life, and the majority outgrow it by 1 year of age. Infants exclusively breastfed at 3 weeks had reduced odds of GERD. Cultural-based changes such as elimination of "heaty or cold" food influence parental perceptions in GERD, which are unique to the Asian population. Understanding the cultural basis for parental perceptions and health-seeking behaviours is crucial in tailoring patient education appropriately for optimal management of infant GERD.

Correlación diagnóstica entre fibrolaringoscopia y videoendoscopia digestiva alta en pacientes con reflujo gastroesofágico y reflujo laringofaríngeo / Diagnostic Correlation Between Fiberlaringoscopy and Upper Gastrointestinal Video Endoscopy in Patients with Gastroesophagic Reflux and Laryngopharyngeal Reflux

Introducción: el reflujo laringofaríngeo (RLF) se origina por el flujo retrógrado de contenido gástrico hacia la faringe, pero es una entidad diferente de la enfermedad por reflujo gastroesofágico (ERGE). El objetivo del estudio fue determinar la correlación entre los signos endoscópicos de la fibrolaringoscopia y la videoendoscopia digestiva alta (VEDA). Material y métodos: estudio observacional, retrospectivo y analítico. Se incluyeron pacientes que consultaron por sintomatología de RLF y ERGE. Los hallazgos visualizados por fibrolaringoscopia flexible, VEDA y biopsia de mucosa gástrica de cada paciente se compararon con la prueba de chi-cuadrado (χ²). Se consideró significativo un valor de p ≤ 0,05. Resultados: se incluyeron 318 pacientes entre 18 y 84 años. Se encontró que el 100 % de los pacientes con esofagitis tenía laringitis (p = 0,001); el 100 % de los pacientes con hernia hiatal tenían RLF (p = 0,001); el 97 % de los pacientes con Helicobacter pylori en la mucosa gástrica tenían RLF (p = 0.001). El 71 % de los pacientes con hernia hiatal tenían esofagitis (p = 0,001). Se encontró una asociación lineal entre la edad y la hernia hiatal con la edad y el RLF (p = 0,03). Conclusiones: en este estudio, los signos encontrados en la fibrolaringoscopia tuvieron una asociación estadística con la VEDA. Aproximadamente el 90 % de los pacientes con signos de laringitis tuvo una correlación con algún grado de esofagitis, esófago de Barrett, hernia hiatal y Helicobacter pylori. También se encontró que la laringitis por RLF y la hernia hiatal se relacionaron directamente con el incremento de la edad.

Introduction: Laryngopharyngeal reflux (LPR) is caused by the retrograde flow of gastric contents towards the pharynx, but it is a different entity from gastroesophageal reflux disease (GERD). The objective of the study was to determine the relationship between the endoscopic signs of fiber laryngoscopy and upper gastrointestinal video endoscopy. Material and methods: Observational, retrospective and analytical study. Patients who consulted for LPR and GERD symptoms were included. The findings visualized by flexible fiber laryngoscopy, upper gastrointestinal video endoscopy and gastric mucosal biopsy of each patient were compared with the Chi-square (χ²) test. A value of p ≤ 0.05 is estimated significantly. Results: 318 patients between 18 and 84 years old were included. A relationship was found in 100% of the patients with esophagitis had laryngitis (p = 0.001); 100% of the patients with hiatal hernia had LPR (p = 0.001); 97% of patients with Helicobacter pylori in the gastric mucosal have LPR (p= 0.001); 71% of patients with hiatal hernia had esophagitis (p = 0.001). A linear association was found between age and hiatal hernia with age and LPR. (p = 0.03). Conclusions: In this study, the signs found in fiber laryngoscopy had a statistical association with the upper gastrointestinal video endoscopy. Approximately 90% of patients with signs of laryngitis had correlation with some degree of esophagitis, Barrett's esophagus, hiatal hernia and Helicobacter pylori. It was also found that LPR and hiatal hernia were directly related to increasing age

Recomendaciones para el diagnóstico y tratamiento de reflujo gastroesofágico en pediatría / Recommendations for the diagnosis and treatment of gastroesophageal reflux in childhood

El reflujo gastroesofágico es una situación frecuente en el primer año de vida. En ausencia de signos y síntomas de alarma, se lo considera fisiológico. No requiere estudios y puede ser abordado por el pediatra con medidas no farmacológicas. La enfermedad por reflujo (definidaporsíntomasmolestosocomplicaciones) debe ser manejada por el gastroenterólogo. Los exámenes complementarios tienen indicaciones precisas y el tratamiento incluye medidas no farmacológicas, farmacológicas y quirúrgicas (si fuera necesario). Nuestro objetivo es describir los diferentes métodos diagnósticos, sus indicaciones y limitaciones, así como los recursos terapéuticos disponibles, incluidas las indicaciones y los efectos adversos

Gastro esophageal reflux is a frequent condition in infants. In the absence of warning symptoms and signs, it is considered physiologic. No exam is required and a non-pharmacologic approach can be instituted by pediatricians. Gastro esophageal reflux disease is characterized by troublesome symptoms or complications and should be managed by a pediatric gastroenterologist. Diagnostic tests have accurate indications and treatment includes pharmacologic and non-pharmacologic measures as well as surgery. Our objective is to describe the different diagnostic methods, their indications and limitations as well as the therapeutic resources available, including indications and adverse effects.

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. MÉTODOS: Estudo retrospectivo, de pacientes com obesidade tipo III, candidatos a cirurgia bariátrica. A avaliação clínica focalizou a presença de sintomas típicos de DRGE (pirose/regurgitação); todos foram submetidos a EMN, PHM e a maior parte à EDA, realizada previamente. 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.

Páncreas ectópico en antro gástrico asociado a síntomas de reflujo. Reporte de un caso / Ectopic pancreas in gastric antrum associated to reflux symptoms. Report of a case

RESUMEN El páncreas ectópico es una entidad poco común. Como tumor submucoso de origen congénito, frecuentemente presenta un curso asintomático, aunque con posibles complicaciones. Su diagnóstico de certeza se basa en la endoscopia, el ultrasonido endoscópico y la histología, que permiten adoptar una conducta expectante o quirúrgica. El paciente estudiado presentó un páncreas ectópico localizado en antro gástrico asociado a síntomas de reflujo gastroesofágico rebeldes a tratamiento, los cuales motivaron el estudio endoscópico, con el consecuente hallazgo de dicha entidad (AU).

ABSTRACT Ectopic pancreas is a little common entity. As congenital-originated sub mucous tumor, it frequently presents an asymptomatic course, though with possible complications. Its definitive diagnosis is based in the endoscopy, endoscopic ultrasound and histology, allowing to adopt an expectant or surgical behavior. The current patient presented an unresponsive-to-treatment ectopic pancreas located in the gastric antrum associated to gastro-esophageal reflux symptoms. This motivated the endoscopic study consequently leading to finding this entity (AU).

Cirugía bariátrica secundaria en el Hospital Universitario San Ignacio / Secondary bariatric surgery at San Ignacio University Hospital

Introducción. La Organización Mundial de la Salud define la obesidad como un incremento en el porcentaje de grasa corporal, generalmente acompañado de aumento en el peso, cuya cantidad y distribución condicionan la salud del individuo. Se caracteriza por ser una enfermedad crónica y de muy difícil manejo. La cirugía bariátrica es un procedimiento cada vez más frecuente, que ha demostrado ser la mejor opción terapéutica para el manejo de la obesidad moderada y severa, enfermedad que ha ido ganado terreno en el mundo. Según la Encuesta Nacional de la Situación Nutricional en Colombia 2015, la incidencia de sobrepeso fue del 37,8 % y de obesidad del 18,7 %. Con el incremento de la cirugía bariátrica primaria, también se ha incrementado la frecuencia de la cirugía bariátrica de revisión, conversión y reversión, siendo la de conversión la más frecuente. Métodos. Estudio observacional retrospectivo en el que se analizaron los pacientes llevados a cirugía bariátrica de conversión en el Hospital Universitario San Ignacio entre 2014 y 2019. Resultados. En nuestra institución la cirugía de conversión corresponde al 8,8 %, y coincide con la estadística mundial para este procedimiento. La causa más frecuente, a diferencia de la literatura, es el reflujo gastroesofágico, seguido de la reganancia de peso. Discusión. Los resultados obtenidos en el Hospital Universitario San Ignacio se asemejan a las cifras mundiales de procedimientos de conversión. Se obtiene la resolución de los síntomas de reflujo gastroesofágico y el manejo adecuado de la reganancia de peso en un alto porcentaje de pacientes, con muy pocas complicaciones

Introduction. The World Health Organization defines obesity as an increase in the percentage of body fat, generally accompanied by an increase in weight, the quantity and distribution of which determine the health of the individual. It is characterized by being a chronic disease and very difficult to manage. Bariatric surgery is an increasingly fre-quent procedure, which has proven to be the best therapeutic option for the management of moderate and severe obesity, a disease that has been gaining ground in the world. According to the 2015 National Survey of the Nutri-tional Situation in Colombia, the incidence of overweight was 37.8% and obesity was 18.7%. With the increase in primary bariatric surgery, the frequency of revision, conversion and reversal bariatric surgery has also increased, with conversion being the most frequent.Methods. Retrospective observational study in which patients underwent bariatric conversion surgery at the San Ignacio University Hospital between 2014 and 2019 were analyzed.Results. In our institution, conversion surgery corresponds to 8.8%, and coincides with the world statistics for this procedure. The most frequent cause, unlike the literature, is gastroesophageal reflux, followed by weight gain.Discussion. The results obtained at the San Ignacio University Hospital are similar to the world figures for con-version procedures. Resolution of gastroesophageal reflux symptoms and proper management of weight gain are obtained in a high percentage of patients, with very few complications

Impacto da pirose e regurgitação no bem-estar de indivíduos da população geral: um inquérito nacional brasileiro / Impact of heartburn and regurgitation on individuals' well-being in the general population: a brazilian national survey

ABSTRACT BACKGROUND: Heartburn and acid regurgitation are typical symptoms usually associated with gastroesophageal reflux disease (GERD). GERD is one of the gastrointestinal diagnosis with higher prevalence worldwide, significantly impairing patients' quality of life. OBJECTIVE: The objective of this study was to analyze the impact of GERD-related symptoms in the Brazilian urban population. METHODS: National telephone survey with community-dwelling Brazilian individuals. Self-reported prevalence and frequency of symptoms (heartburn / regurgitation) were assessed. Individuals rated the impact of symptoms in their general well-being using a numeric scale from 1 to 10 (1 = no impact; 10 = very intense, preventing the person to eat and perform daily routine activities). Descriptive and bivariate statistical analyses were performed. RESULTS: The final sample was comprised of 1,773 subjects, 935 (52.7%) females, an average of 40 years old. The prevalence of heartburn and regurgitation in the past 6 months was 26.2% (n=466) and 11.0% (n=196), respectively. Women presented higher prevalence (heartburn n=266, 28.5% and regurgitation n=119, 12.7%) than men (n=200, 23.1% and n=78, 8.9%, respectively) (P<0.05). Heartburn in the past week was reported by 175 individuals (9.8%), while regurgitation episodes by 67 (3.8%). Absence of impact of the symptom in the overall well-being was observed for 82 subjects (17.6%) with heartburn and 18 individuals (9.2%) with regurgitation. Very intense impact was reported by 46 subjects (9.8%) with heartburn and 41 (20.9%) with regurgitation. Women's well-being was more affected than men's (mean score 5.45 vs 4.71, P<0.05). CONCLUSION: Heartburn and regurgitation were frequent symptoms, women with higher prevalence. These symptoms led to a substantial impact on individuals' well-being, women being more affected.

RESUMO CONTEXTO: Pirose e regurgitação ácida são sintomas típicos usualmente relacionados à doença do refluxo gastroesofágico (DRGE). A DRGE é um dos diagnósticos gastrointestinais com maior prevalência mundial, afetando significativamente a qualidade de vida dos pacientes. OBJETIVO: Analisar o impacto de sintomas relacionados à DRGE em uma amostra da população brasileira urbana. MÉTODOS: Inquérito nacional via telefone com indivíduos brasileiros em contexto comunitário. O inquérito foi conduzido entre 6 de agosto e 12 de setembro de 2018. A prevalência autorrelatada e a frequência dos sintomas foram avaliadas. Os respondentes classificaram o impacto dos sintomas no seu bem-estar geral utilizando uma escala numérica de 1 a 10 (1 = ausência de impacto; 10 = impacto muito grave, impedindo a pessoa de comer ou realizar atividades da vida diária). Análises estatísticas descritivas e bivariadas foram conduzidas. RESULTADOS: A amostra final foi constituída por 1.773 indivíduos, 935 (52,7%) mulheres, com idade média de 40 anos. A prevalência de pirose e regurgitação nos últimos 6 meses foi de 26,2% (n=466) e 11,0% (n=196), respectivamente. Sexo feminino (pirose n=266, 28,5% e regurgitação n=119, 12,7%) apresentou prevalência mais alta do que o masculino (n=200, 23,1% e n=78, 8,9%, respectivamente) (P<0,05). Pirose na última semana foi relatada por 175 indivíduos (9,8%), enquanto episódios de regurgitação por 67 (3,8%). Ausência de impacto dos sintomas no bem-estar geral dos indivíduos foi observada para 82 respondentes (17,6%) com pirose e 18 (9,2%) daqueles com regurgitação. Impacto muito grave foi reportado por 46 (9,8%) indivíduos com pirose e 41 (20,9%) com regurgitação. Sexo feminino foi mais afetado pelos sintomas do que o masculino. CONCLUSÃO: Pirose e regurgitação foram bastante frequentes sendo o sexo feminino mais afetado. Tais sintomas levaram a impacto no bem-estar dos indivíduos, com maior prejuízo para mulheres.

Actualización en la interpretación de la medición del pH e impedanciometría / Updated interpretation of Impedance-pH monitoring

Resumen La enfermedad por reflujo gastroesofágico (ERGE) se define como el tránsito anormal del contenido gástrico hacia el esófago, que se da por una alteración de la barrera antirreflujo, causando síntomas o complicaciones. Para su correcto diagnóstico y abordaje terapéutico, se requiere de la integración de hallazgos clínicos, endoscópicos y monitorización del pH esofágico en 24 horas con o sin impedanciometría, la cual debe ser realizada con especificaciones técnicas, y su interpretación debe basarse en la mejor evidencia clínica disponible, con el objetivo de tener diagnósticos precisos que permitan tomar las mejores decisiones con los pacientes. Recientemente, en el Consenso de Lyon se han incorporado nuevas directrices para el diagnóstico de ERGE por monitorización de pH esofágico, las cuales se revisan en este artículo.

Abstract Gastroesophageal reflux disease (GERD) is defined as the abnormal transit of gastric contents into the esophagus. It is caused by an alteration of the anti-reflux barrier, causing multiple symptoms or complications. In order to achieve accurate diagnosis and proper therapeutic approach, integration of clinical findings, endoscopic findings and 24-hour esophageal pH monitoring, with or without impedancometry, is required. These tests must be performed following technical specifications and their interpretation must be based on the best clinical evidence available to obtain accurate diagnoses that allow making the best decisions to the benefit of patients. Recently, the Lyon Consensus incorporated new guidelines for the diagnosis of GERD by esophageal pH monitoring, which are reviewed in this paper.

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.

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.

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

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

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

Anti-reflux procedures after roux-en-y gastric bypass / Procedimentos anti-refluxo após bypass gástrico em y-de roux

ABSTRACT Background: Roux-en-Y gastric bypass (RYGB) has been the choice of bariatric procedure for patients with symptomatic reflux - and is known to be effective in reducing the need for anti-reflux medication postoperatively. However, a small number of RYGB patients can still develop severe reflux symptoms that require a surgical intervention. Aim: To examine and describe the patient population that requires an anti-reflux procedure after RYGB evaluating demographics, characteristics, symptoms and diagnosis Methods: A retrospective chart review was performed on 32 patients who underwent a hiatal hernia repair and/or Nissen fundoplication after RYGB Jul 1st, 2014 and Dec 31st, 2019. Patients were identified using the MBSAQIP database and their electronic medical records were reviewed. Results: Most patients were female (n=29, 90.6%). The mean age was 52.8 years and the mean body mass index (BMI) was 34.1 kg/m2 at the time of anti-reflux procedure. Patients underwent the anti-reflux procedure at a mean of 7.9 years after the RYGB procedure. The mean percentage of excess BMI loss during the time between RYGB and anti-reflux procedure was 63.4%. Conclusions: Female patients with a significant weight loss may develop a severe reflux symptoms years after RYGB. Complaints of reflux after RYGB should not be overlooked. Careful follow-up and appropriate treatment (including surgical intervention) is needed for this population.

RESUMO Racional: O bypass gástrico em Y-de-Roux (RYGB) tem sido o procedimento bariátrico de escolha para pacientes com refluxo sintomático - e é conhecido por ser eficaz na redução da necessidade de medicação anti-refluxo no pós-operatório. No entanto, um pequeno número de pacientes com RYGB ainda pode desenvolver sintomas de refluxo graves que requerem uma intervenção cirúrgica. Objetivo: Examinar e descrever a população de pacientes que requer procedimento anti-refluxo após RYGB avaliando dados demográficos, características, sintomas e diagnóstico. Métodos: Revisão retrospectiva de prontuários foi realizada em 32 pacientes submetidos a hérnia hiatal e / ou fundoplicatura Nissen após RYGB em 1º de julho de 2014 a 31 de dezembro de 2019. Os pacientes foram identificados por meio do banco de dados MBSAQIP e seus prontuários eletrônicos foram revisados. Resultados: A maioria dos pacientes era do sexo feminino (n = 29 - 90,6%). A média de idade foi de 52,8 anos e o índice de massa corporea (IMC) médio de 34,1 kg / m2 na época do procedimento anti-refluxo. Os pacientes foram submetidos ao procedimento anti-refluxo em média 7,9 anos após o procedimento do BGYR. A porcentagem média de perda do excesso de IMC durante o tempo entre o BGYR e o procedimento anti-refluxo foi de 63,4%. Conclusões: Pacientes do sexo feminino com perda de peso significativa podem desenvolver sintomas graves de refluxo anos após o BGYR. Sintomas de refluxo após RYGB não devem ser negligenciadas. Acompanhamento cuidadoso e tratamento adequado (incluindo intervenção cirúrgica) são necessários para essa população.

Wireless ph monitoring and conventional esophageal ph monitoring: comparative study of discomfort, limitations in daily activities and complications / Phmetria sem cateter e phmetria esofágica convencional: estudo comparativo do desconforto, limitações das atividades diárias e complicações

ABSTRACT Background: The catheter of the esophageal pH monitoring is associated with nasal and throat discomfort, and different behave in patients. The capsule of the wireless pH monitoring may cause chest pain and complications. Aim: To compare the wireless and conventional pH monitoring concerning the degree of discomfort and limitations in daily activities, complications, ability to diagnose pathological reflux, and costs. Methods: Twenty-five patients with symptoms of gastroesophageal reflux were prospectively submitted, in a simultaneous initial period, to 24-hour catheter esophageal pH monitoring and 48-hour wireless system. After removing each system, patients underwent a specific clinical questionnaire. Results: Fifteen patients (60%) pointed a higher discomfort in the introduction of the capsule (p=0.327). Discomfort and limitations in daily activities were lower on 2nd day (p<0.05); however, continued to be expressive (32% to 44%). Chest pain occurred in 13 (52%) patients. The diagnostic gain of pathological reflux was 12% with the wireless system (p=0.355). Conclusions: 1) There is no significant difference between the discomfort mentioned in the introduction of the capsule and the catheter; 2) during reflux monitoring, the wireless system provides significant less discomfort and limitations in daily activities; 3) there is no significant difference between the two methods in the ability to diagnose pathological reflux; 4) wireless pH monitoring has higher cost.

RESUMO Racional: O cateter da pHmetria esofágica associa-se ao desconforto nasal e na garganta, e comportamento diferente nos pacientes. A cápsula da pHmetria sem cateter pode causar dor torácica e complicações. Objetivo: Comparar as pHmetrias sem cateter e a convencional, em relação ao desconforto e limitações das atividades diárias, complicações, capacidade de diagnosticar refluxo patológico, e custos. Métodos: Vinte e cinco pacientes com sintomas de refluxo gastroesofágico foram prospectivamente submetidos, em um período inicial simultâneo, à pHmetria esofágica com cateter durante 24 h e à pHmetria sem cateter durante 48 h. Após a retirada de cada método, pacientes responderam o questionário clínico específico. Resultados: Quinze pacientes (60%) relataram maior desconforto na introdução da cápsula (p=0,327). Desconforto e limitações das atividades diárias foram menores no 2º dia (p< 0,05); entretanto, continuaram sendo expressivos (32% a 44%). Dor torácica ocorreu em 13 (52%) pacientes. O ganho diagnóstico no refluxo patológico foi de 12% com o sistema sem cateter (p=0,355). Conclusões: 1) Não há diferença significativa entre o desconforto relatado na introdução da cápsula e do cateter; 2) durante a monitorização do refluxo, o sistema sem cateter proporciona significativo menor desconforto e limitações das atividades diárias; 3) não há diferença significativa entre os dois métodos na capacidade de diagnosticar o refluxo patológico; 4) pHmetria sem cateter tem custo maior.
