Abstract:
Objective To investigate the consistency between colonoscopic Boston bowel preparation score and the bowel cleanliness evaluated by pre-endoscopy naked eye faecal observation,so as to provide a guidance on bowel preparation.Methods From September 2018 to June 2019,convenience sampling method was used to select 150 inpatients who underwent colonoscopy in the Department of Gastroenterology of a tertiary hospital in Guangzhou as the research objects.Before colonoscopy,the compound polyethylene glycol electrolyte powder was taken orally according to the bowel preparation plan for cleaning the colorectum.Before the colonoscopic examination,the naked eye observation method by nurses was used to observe the transparency of the excreta to evaluate the cleanliness of colorectum.Then the colorectal cleanliness was evaluated by endoscope by the operator using the Boston bowel preparation assessment scale(BBPS)during colonoscopy.Results A total of 145 patients completed the study.The cleanliness of bowel preparation was 93.1%with the naked eye observation and 88.27%with colonoscopy.There was no significant difference between the two assessment methods in judging the effectiveness of bowel preparation(P<0.05).The sensitivity of naked eye observation in judging bowel preparation was 96.10%with a 29.41%of specificity.The positive predictive value was 91.11%,and the negative predictive value was 50%(Kappa=0.310,P<0.001).Conclusion The naked eye observation and evaluation method for bowel preparation has advantages in high sensitivity,low specificity,high positive predictive value and low negative predictive value.It can be used as a preliminary evaluation method for cleanliness of colorectum before colonoscopy.
