Resumen
Alentar el uso de pequeñas descargas durante la preparación del intestino para la colonoscopia redujo significativamente el consumo de agua en aproximadamente 3,5 litros por paciente. Esta simple intervención promueve prácticas de endoscopia más ecológicas sin afectar la calidad de la limpieza intestinal.
Área de la Ciencia:
- Gastroenterología
- Sustentabilidad medioambiental en la asistencia sanitaria
- Intervenciones de salud pública
Sus antecedentes:
- La colonoscopia requiere una extensa preparación intestinal, que a menudo implica un uso significativo de agua.
- Los baños japoneses suelen tener opciones de doble descarga (grande/pequeño).
- El consumo de agua durante la preparación del intestino es un aspecto poco estudiado de la endoscopia.
Objetivo del estudio:
- Evaluar si la promoción de pequeñas descargas para heces acuosas durante la preparación del intestino puede disminuir el consumo total de agua.
- Evaluar el impacto de una intervención infográfica en el consumo de agua durante la preparación de la colonoscopia.
- Determinar si las medidas de ahorro de agua afectan a la eficacia de la limpieza intestinal o a la ingesta de líquidos del paciente.
Principales métodos:
- Un estudio observacional prospectivo de un solo centro en el que participaron 220 pacientes sometidos a colonoscopia.
- Se compararon dos grupos: un grupo de control (agua no intencional [NW]) que recibió instrucciones estándar y un grupo de intervención (agua verde [GW]) expuesto a una infografía que promueve pequeñas descargas.
- Se recopilaron datos sobre el uso de agua, la ingesta de líquidos y la calidad de la limpieza intestinal durante un período de diez meses.
Principales resultados:
- El grupo de GREEN-Water (GW) demostró un consumo medio de agua total significativamente menor (31,5 L) en comparación con el grupo de agua no intencional (35,0 L) (p < 0,005).
- Esto representa una reducción aproximada de 3,5 L de agua por procedimiento de colonoscopia.
- No se encontraron diferencias estadísticamente significativas en la ingesta de líquidos del paciente o en la calidad de la limpieza intestinal entre los dos grupos.
Conclusiones:
- Una intervención educativa que utilice carteles para fomentar la selección adecuada del enjuague es un método sencillo y eficaz para reducir el consumo de agua durante la preparación del intestino.
- Esta estrategia contribuye a las iniciativas de "endoscopia verde" al minimizar el impacto ambiental.
- Los hallazgos sugieren que promover el uso consciente del agua en entornos de atención médica es factible y beneficioso.

494
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
