How to approach esophagogastric junction outflow obstruction?

Abstract: The diagnosis of esophagogastric junction outflow obstruction (EGJOO) is currently based on high‐resolution esophageal manometry and is characterized by impaired EGJ relaxation with preserved esophageal peristalsis. This condition has been defined by the Chicago Classification as a major esophageal motility disorder, although its clinical significance is controversial since heterogeneous and irrelevant presentations have been reported. EGJOO commonly has a benign clinical course, with spontaneous resolution, b… Show more

“…Based on CCv3.0, a significant proportion of EGJOO is associated with the effect of artifact, hiatal hernia, mechanical obstruction, opioid effect, or gastric volvulus, but not primary LES dysfunction. Hence, numerous studies focused on the identification of primary motility disorders and excluded motility patterns secondary to medication use, mechanical obstruction, previous surgery, or endoscopic interventions[ 3 , 4 , 17 ], which are critical in making appropriate therapeutic decisions. Since the morphology of LES is affected by position, the CCv4.0 defines IRP in the upright position and IBP; thus, the Chicago Classification update has reduced the number of clinically irrelevant diagnoses and improved the specificity for EGJOO diagnosis[ 7 , 17 , 18 ], enabling us to avoid irreversible treatment for these conditions.…”

“…Por lo mencionado anteriormente, los pacientes sin disfagia ni dolor torácico, así como los que tienen algunas alteraciones pero no alcanzan todos los criterios manométricos de CC4.0 para EGJOO conclusiva, deben ser manejados conservadoramente, con la recomendación de hacer controles periódicos y aún más en caso de aparición de síntomas 42,43 . Los pacientes sintomáticos con EGJOO no conclusiva en la MAR deben completar su evaluación con un estudio baritado cronometrado o un FLIP 2 .…”

“…Como en todos los pacientes sometidos a una MAR, es recomendable tener previamente un estudio endoscópico, incluidas biopsias del esófago, en caso de síntomas como disfagia o dolor torácico. 64 Al momento de la MAR, es importante contar con una adecuada evaluación de la historia, especialmente para tener antecedentes del uso de fármacos como opioides y de cirugías gastroesofágicas, además de la evaluación de los síntomas.…”
