The Mexican consensus on non-cardiac chest pain

Introduction: Non-cardiac chest pain is defined as a clinical syndrome characterized by ret-rosternal pain similar to that of angina pectoris, but of non-cardiac origin and produced byesophageal, musculoskeletal, pulmonary, or psychiatric diseases. Aim: To present a consensus review based on evidence regarding the definition, epidemiology,pathophysiology, and diagnosis of non-cardiac chest pain, as well as the therapeutic options forthose patients. Methods Three general coordinators carried out a literature review of all articles published inEnglish and Spanish on the theme and formulated 38 initial statements, dividing them into 3 maincategories: 1) definitions, epidemiology, and pathophysiology, 2) diagnosis, and 3) treatment.The statements underwent 3 rounds of voting, utilizing the Delphi system. The final statementswere those that reached > 75% agreement, and they were rated utilizing the GRADE system. Results and conclusions The final consensus included 29 statements. All patients presentingwith chest pain should initially be evaluated by a cardiologist. The most common cause of non-cardiac chest pain is gastroesophageal reflux disease. If there are no alarm symptoms, the initialapproach should be a therapeutic trial with a proton pump inhibitor for 2-4 weeks. If dysphagiaor alarm symptoms are present, endoscopy is recommended. High-resolution manometry isthe best method for ruling out spastic motor disorders and achalasia and pH monitoring aidsin demonstrating abnormal esophageal acid exposure. Treatment should be directed at thepathophysiologic mechanism. It can include proton pump inhibitors, neuromodulators and/orsmooth muscle relaxants, psychologic intervention and/or cognitive therapy, and occasionallysurgery or endoscopic therapy

Consenso mexicano sobre dolor torácico no cardiaco

Introducción: Dolor torácico no cardíaco (DTNC) se define como un síndrome clínico caracte-rizado por dolor retroesternal semejante a la angina de pecho, pero de origen no cardiaco ygenerado por enfermedades esofágicas, osteomusculares, pulmonares o psiquiátricas.Objetivo: Presentar una revisión consensuada basada en evidencias sobre definición, epidemio-logía, fisiopatología, diagnóstico y opciones terapéuticas para pacientes con DTNC.Métodos: Tres coordinadores generales realizaron una revisión bibliográfica de todas las publi-caciones en inglés y espa˜nol sobre el tema y elaboraron 38 enunciados iniciales divididosen tres categorías principales: 1) definiciones, epidemiología y fisiopatología; 2) diagnóstico,y 3) tratamiento. Los enunciados fueron votados (3 rondas) utilizando el sistema Delphi, y losque alcanzaron un acuerdo > 75% fueron considerados y calificados de acuerdo con el sistemaGRADE. Resultados y conclusiones: El consenso final incluyó 29 enunciados Todo paciente que debutacon dolor torácico debe ser inicialmente evaluado por un cardiólogo. La causa más común deDTNC es la enfermedad por reflujo gastroesofágico (ERGE). Como abordaje inicial, si no existensíntomas de alarma, se puede dar una prueba terapéutica con inhibidor de bomba de pro-tones (IBP) por 2-4 semanas. Si hay disfagia o síntomas de alarma, se recomienda hacer unaendoscopia. La manometría de alta resolución es el mejor método para descartar trastornosmotores espásticos y acalasia. La pHmetría ayuda a demostrar exposición esofágica anormal alácido. El tratamiento debe ser dirigido al mecanismo fisiopatológico, y puede incluir IBP, neu-romoduladores y/o relajantes de músculo liso, intervención psicológica y/o terapia cognitiva,y ocasionalmente cirugía o terapia endoscópica.

Nonspecific motility disorders, irritable esophagus, and chest pain

This paper presents commentaries on whether Starling's law applies to the esophagus; whether erythromycin affects esophageal motility; the relationship between hypertensive lower esophageal sphincter and vigorous achalasia; whether ethnic- and gender-based norms affect diagnosis and treatment of esophageal motor disorders; health care and epidemiology of chest pain; whether normal pH excludes esophageal pain; the role of high-resolution manometry in noncardiac chest pain; whether pH-impedance should be included in the evaluation of noncardiac chest pain; whether there are there alternative therapeutic options to PPI for treating noncardiac chest pain; and the usefulness of psychological treatment and alternative medicine in noncardiac chest pain. \ua9 2013 New York Academy of Sciences

Treatment of Boerhaave’s syndrome

Boerhaave's syndrome is the spontaneous transmural rupture of the esophagus. A high degree of clinical suspicion is a prerequisite for its prompt diagnosis, and early therapeutic intervention reduces its associated morbidity and mortality. Factors that influence the outcome are location and extent of perforation and the timing of medical or surgical treatment. Boerhaave's syndrome is the most lethal perforation of the gastrointestinal tract. Delay in intervention relates directly to increased mortality. Despite advances in surgical techniques and endoscopic therapies, this disorder still has high morbidity and mortality rates. The outcome of patients with this disorder is dependent upon the prompt and accurate diagnosis. Initial stabilization of the patient with intravenous fluids and antibiotics is of key importance, with subsequent decisive therapy initiated using either a conservative medical or endoscopic or surgical approach. Boerhaave's syndrome often occurs in otherwise-relatively healthy patients. This postemetic perforation of the esophagus can result in a devastating injury that usually is exacerbated by delayed diagnosis. This article will focus on its clinical presentations and review its potentially applicable therapies
