A colonoscopy Boston score of 6 represents a basic pass in colonoscopy cleanliness. The Enteroscopy Boston Score is an index that evaluates the degree of cleanliness of the bowel for enteroscopy. The scores range from 0 to 3 for the cecum and ascending colon, the transverse and descending colon, the rectum and the sigmoid colon; and 0 for the amount of fluid in the whole colon. The total Bowel Boston score was 9 points. A score of 8 to 9 indicates a relatively high level of cleanliness; 7 is good; and a score of less than 6 indicates poor bowel preparation, which could potentially affect the results. Therefore, a Bowel Boston Score of 6 is basically normal and is generally adequate for screening tests. In order to improve the accuracy, you can also follow the doctor’s instructions to further clean the bowel before checking, and you can also regularly review the colonoscopy.
