Answer

Fiberoptic flexible colonoscopy can be utilized in two different fashions. The historical urgent colonoscopy includes rapid bowel preparation using 1-liter volume cathartic agents such as GoLYTELY every 30 to 45 minutes. This rapid preparation is completed in 3-4 hours using 4-6 L of GoLYTELY. [5] Placement of an NG tube with/without 10 mg intravenous (IV) metoclopramide can be used in patients who cannot tolerate rapid drinking. Emergent/immediate unprepared hydroflush colonoscopy can be also performed in an emergent fashion. [42]
