Resumen
Las elevaciones del segmento ST en el ECG pueden imitar ataques cardíacos, pero pueden indicar problemas intraabdominales como obstrucción intestinal. El diagnóstico y la intervención rápidos para la causa subyacente resolvieron los cambios en el ECG en un paciente con una hernia ventral.
Área de la Ciencia:
- Cardiología
- Gastroenterología
- Medicina de Emergencia
Sus antecedentes:
- La elevación del segmento ST en electrocardiogramas (ECG) típicamente indica infarto agudo de miocardio (ataque cardíaco).
- Sin embargo, condiciones no cardíacas, como la patología intraabdominal, también pueden causar elevación del segmento ST.
- Reconocer estos imitadores es crucial para el manejo adecuado del paciente.
Objetivo del estudio:
- Informar un caso de elevación del segmento ST que imita un infarto de miocardio debido a obstrucción del intestino delgado.
- Destacar la importancia de considerar la patología intraabdominal en pacientes con síntomas y cambios en el ECG atípicos.
- Discutir las implicaciones diagnósticas y de manejo de este fenómeno.
Principales métodos:
- Reporte de caso de una mujer de 75 años que presenta dolor torácico y epigástrico.
- Análisis de ECG que muestra elevaciones del segmento ST inferior.
- Examen físico e imágenes que confirman hernia ventral encarcelada y obstrucción intestinal.
- Manejo que incluye descompresión con sonda nasogástrica y posterior reparación de la hernia.
Principales resultados:
- La descompresión de la obstrucción intestinal condujo a la resolución inmediata de las elevaciones del segmento ST.
- Los cambios en el ECG del paciente se normalizaron sin cateterismo cardíaco.
- La causa subyacente se identificó como una patología intraabdominal obstructiva (hernia ventral encarcelada).
Conclusiones:
- La obstrucción del intestino delgado puede presentarse con hallazgos de ECG indistinguibles del infarto de miocardio con elevación del ST (STEMI).
- Se requiere un alto índice de sospecha de patología intraabdominal en pacientes con presentaciones atípicas.
- Las elevaciones del segmento ST debidas a patología intraabdominal pueden ocurrir preferentemente en las derivaciones inferiores, un patrón que requiere una mayor investigación.

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

01:22Appendicitis-I: Introduction
2.1K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

01:25Assessment of the Rectum and Anus
1.0K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
