Q; 52 year old male is admitted to ICU with lower GI bleed and have 2 episodes in last 24 hours. GI service wants to do "hydroflush colonoscopy". What is hydroflush colonoscopy?
Answer: Still experimental but in cases where bowel preparation may become a challenge and diagnosis is desired, hydroflush colonoscopy may be an option. Without requiring any bowel preparation, it uses tap-water enema aided by water-jet pumps and mechanical suction devices.
