Core Tip

Core tip: Despite the important diagnostic and clinical utility of colonoscopy, serious electrolyte disorders and impaired kidney function have been observed with the agents used for bowel cleansing. The aim of this paper is to present these complications and discuss their prevention and management.

Colonoscopy is widely used worldwide particularly for colon cancer screening and detection. The use of bowel cleansing agents one or two days prior the procedure improves its diagnostic utility. Various preparations have been developed throughout the years, but few of them are currently being used, specifically polyethylene glycol and oral sodium phosphate (OSP) solutions, because of their ease of use and safety profile[1]. As minimal volume of oral intake is required with OSP, this is associated with less patient discomfort, greater compliance and improved colonic cleansing compared with polyethylene glycol[2]. However, serious electrolyte disorders and impaired kidney function have been observed with these agents and particularly with OSP. The aim of this paper is to present these complications and discuss their prevention and management. Disturbances in electrolyte levels with less frequently used bowel cleansing agents are also mentioned.
