Endoscopy
-
The endoscopic literature published during the past year has once again confirmed that there is significant variation from country to country regarding whether or not patients wish to receive conscious sedation during endoscopy (and particularly colonoscopy) - and there may even be variation from one endoscopic unit to another within the same country. Particular attention has been given to attempts to identify "ideal" candidates for conscious sedation, and to the importance of providing patients with information before the procedure. It has been shown that patients who receive detailed information about a medical procedure beforehand are able to benefit from this. ⋯ Several papers have proposed "ideal formulas" for bowel preparation for endoscopic procedures. Various regimens have been proposed as alternatives to polyethylene glycol electrolyte lavage solution (PEG-ELS) and sodium phosphate compounds, with different results. On the whole, there is still little information regarding the best and most cost-effective method of bowel cleansing for colonoscopy and flexible sigmoidoscopy.
