[Acute esophageal necrosis: a retrospective case series]. / Esofagitis necrosante aguda: análisis retrospectivo.

BACKGROUND: Acute esophageal necrosis has been considered a rare event. It is defined as the presence of diffuse dark pigmentation of the esophagus on upper endoscopy. Its incidence has not yet been established. The pathogenesis remains unknown. PATIENTS AND METHODS: A retrospective analysis of clinical, laboratory, endoscopic, and histological data, and of the clinical course of 11 patients with acute necrotizing esophagitis was carried out over a 2-year period. RESULTS: Among 3,976 patients who underwent upper endoscopy, 11 (0.28%) with acute esophageal necrosis were identified. Nutritional status was poor for 6 patients. Complete resolution of acute esophageal necrosis without further recurrence was observed in 4. One stricture appeared during follow-up and other patient developed new-onset acute esophageal necrosis. Seven patients died, but no death was directly related to acute esophageal necrosis. CONCLUSIONS: The incidence of acute esophageal necrosis in our series is 0.28%. Acute esophageal necrosis is associated with high mortality rates.

Introducción: la esofagitis necrosante aguda es una entidadrara. Se reconoce por el aspecto negro difuso del esófago a la endoscopia.Su incidencia e patogénesis se desconoce.Pacientes y métodos: se analizaron retrospectivamente 11pacientes con esofagitis necrosante aguda desde el punto de vistade los datos clínicos, de laboratorio y endoscopicos en 2 años.Resultados: se analizaron las endoscopias realizadas a 3.976pacientes, observándose esofagitis necrosante aguda en 11 pacientes.El estado nutricional era malo en 6 pacientes. La resolucióncompleta de la esofagitis se observó en cuatro pacientes. Duranteel seguimiento se observó una estenosis en un paciente y unnuevo episodio de esofagitis necrosante aguda en otro paciente.Siete pacientes fallecieron, pero esta elevada mortalidad parecedeberse a las enfermedades de base y no es atribuible a las lesionesde la esofagitis necrosante.Conclusiones: la incidencia de esofagitis necrosante agudaen nuestra serie fue 0,28%. La esofagitis necrosante aguda tieneuna elevada mortalidad
