“…These procedures should be done in negative pressure endoscopy rooms, and if negative pressure rooms are not available, it should be in the negative pressure ICU rooms or the operating room. Endoscopes after use should undergo standard manual cleaning followed by high-level disinfection (HLD) which refers to the use of FDA cleared chemical germicides capable of destroying all microorganisms (virus, fungi, mycobacterium, and vegetative bacteria) with the exception of some bacterial spores [ 75 – 77 ]. At present, the ASGE and ACG consider this technique adequate enough for disinfection and reprocessing of endoscopes following any procedure in confirmed or suspected patients with SAR-CoV-2.…”

The worldwide pandemic of COVID-19, caused by the virus SARS-CoV-2, continues to cause significant morbidity and mortality in both low-and high-income countries. Although COVID-19 is predominantly a respiratory illness, other systems including gastrointestinal (GI) system and liver may be involved because of the ubiquitous nature of ACE-2 receptors in various cell lines that SARS-CoV-2 utilizes to enter host cells. It appears that GI symptoms and liver enzyme abnormalities are common in COVID-19. The involvement of the GI tract and liver correlates with the severity of disease. A minority (10-20%) of patients with COVID-19 may also present initially with only GI complaints. The most common GI symptoms are anorexia, loss of smell, nausea, vomiting, and diarrhea. Viral RNA can be detected in stool in up to 50% of patients, sometimes even after pharyngeal clearance, but it is unclear whether fecal-oral transmission occurs. Liver enzymes are elevated, usually mild (2-3 times), in a substantial proportion of patients. There are many confounding factors that could cause liver enzyme abnormalities including medications, sepsis, and hypoxia. Although infection rates in those with preexisting liver disease are similar to that of general population, once infected, patients with liver disease are more likely to have a more severe disease and a higher mortality. There is a paucity of objective data on the optimal preventive or management strategies, but few recommendations for GI physicians based on circumstantial evidence are discussed.

“…Durante los estudios, estos dispositivos médicos pueden contaminarse con sangre, fluidos corporales y secreciones, que pueden contener no solo materia orgánica, sino también microorganismos potencialmente patógenos 3,4 . Debido al complejo diseño de los endoscopios con múltiples canales estrechos, son instrumentos difíciles de limpiar y desinfectar 5,6 . Otro aspecto importante que contribuye a la falla de la desinfección es la capacidad de algunas bacterias para formar biopelículas en las partes difíciles de alcanzar del endoscopio, principalmente cuando existe algún daño físico en el dispositivo 7 .…”

reprocesados, mediante cultivo del agua de irrigación y la obtenida posterior a un cepillado de los canales. Un objetivo secundario fue determinar la sensibilidad antimicrobiana de los patógenos aislados en ambos métodos. Método: Un total de 26 endoscopios (duodenoscopios, gastroscopios, colonoscopios, broncoscopios y ecoendoscopios) fueron sometidos a limpieza y reprocesamiento automático antes de su uso en pacientes del Hospital Juárez de México. Los endoscopios limpios y reprocesados se sometieron simultáneamente a dos métodos de prueba bacteriológica basados en ausencia de cepillado (método A) y cepillado (método B) de los canales. Las cepas bacterianas aisladas después del cultivo de canales se identificaron a nivel de género y especie y se sometieron a pruebas de resistencia antimicrobiana. Resultados: El método A reveló cero tasa de contaminación bacteriana residual en ambos canales (succión y trabajo). Los resultados microbiológicos obtenidos por el método B revelaron tasas de contaminación bacteriana del 30.7%. Se identificaron cepas bacterianas pertenecientes a las familias Enterobacteriaceae, Bacillaceae, Pseudomonadaceae, Micrococcaceae y Staphylococcaceae. Se detectaron altas tasas de resistencia antimicrobiana contra 12 antibióticos probados de ocho familias diferentes. Conclusión: La implementación de la vigilancia microbiológica del reprocesamiento de endoscopios con métodos modificados de muestreo es necesaria para prevenir infecciones asociadas a la atención de la salud por procedimientos endoscópicos.
