“…On the one hand, it is theorized that MWS is the more relevant test in achalasia due to its superiority in detecting subtle resistance to flow over the EGJ. Elvevi et al found that only MWS, and not MRS or single-water swallows, was able to identify very subtle resistance to flow (as manifest by an increased esophagogastric pressure gradient) that remained in patients with achalasia who had been successfully treated with pneumatic dilation (PD) [35]. Furthermore, Ang et al recently determined normal and pathological values for MWS.…”

Adjunctive testing with viscous substances or larger water volumes should be used routinely as it improves the accuracy of achalasia diagnosis. Chronic opiate use can mimic achalasia. The timed barium swallow remains the best test for assessments of disease severity and prognostication, but the functional lumen-imaging probe, a newer tool which measures esophagogastric junction distensibility using impedance planimetry, is emerging as a potentially more powerful tool for these purposes. Functional esophagogastric junction outflow obstruction is possibly part of the achalasia spectrum. By addressing the potential pitfalls described, and through routine and standardized use of the diagnostic tools mentioned herein, the accuracy of diagnosis, severity assessment, and prognostication of achalasia can be improved.

“…Una respuesta anormal consiste en una inhibición incompleta (cuando se ven fragmentos de contracción durante el período esperado de inhibición) o contracción subóptima (la secuencia posterior a múltiples degluciones rápidas falla para demostrar un aumento de la contracción del músculo liso). Las múltiples degluciones rápidas de bajo volumen evalúan la reserva peristáltica, mientras que las degluciones de grandes volúmenes identifican un aumento de la resistencia al flujo (4,13).…”

Con la introducción de la manometría esofágica de alta resolución se revelaron patrones no identificados previamente de la función esofágica. De igual forma, este metodo diagnóstico adiciona patrones de presión topográfica de la presión esofágica, lo que lleva al desarrollo de nuevas herramientas para el análisis y clasificación de desórdenes motores esofágicos. En la actualidad la clasificación de Chicago3.0 la herramienta de análisis de los diferentes trastornos motores esofágicos. En Colombia, cada día se ve el crecimiento en la realización de este estudio. El artículo propone hacer una revisión de cómo realizar e interpretar una manometría esofágica de alta resolución y clasificar los diferentes trastornos de la motilidad esofágica según la última actualización de la clasificación de Chicago 3.0.

“…With the advent of HRM, further development of MRS has occurred. Two types of exercises have been used: a low‐volume one, 10 mL of water with five 2‐mL swallows every 2–3 s; and a high‐volume one, also referred to as a free‐drinking test, where 200 mL of water is consumed within 30 seconds . Shaker et al .…”

Standard tests in clinical practice commonly fail to demonstrate a clear esophageal etiology for symptoms such as heartburn, dysphagia, or chest pain. Over the years, various provocative measures have been developed to provide a better understanding of the origins of such symptoms. Some measures, such as esophageal acid infusion or changing bolus consistency, can be easily incorporated into clinical practice. Others, such as multimodal stimulation systems, are more technically demanding. They have contributed to a better understanding of esophageal physiology in health and disease. Their role in clinical decision making is still evolving. This focused review provides a summary of the esophageal nociceptive pathways and how provocative testing can be used to interrogate their integrity.
