METHODSTwo hundred patients were randomly assigned to the PEG or NaP groups at the same ratio. The NaP group patients took 30 tablets with 2 L of clear liquid, while the PEG group patients took 2L of PEG. Tolerability was assessed by a questionnaire about taste, volume, and the overall impression. The bowel cleansing quality was evaluated by colonoscopists. RESULTSAlthough NaP showed better tolerability in terms of taste, volume and overall impression (P < 0.01, P < 0.01 and P = 0.02, respectively), the overall cleansing quality was better in the PEG group (P < 0.01). A subgroup analysis, stratified by sex and age, indicated that NaP was associated with better tolerability and equivalent bowel cleansing quality in females of < 50 years of age. CONCLUSIONDespite the better tolerability, the use of 30 NaP tablets with 2 L of clear liquid should be limited due to its lower cleansing quality; however, in certain cases the regimen may deserve consideration, particularly in cases involving young women.展开更多
