Colonic cleanliness was assessed using the Boston Bowel Preparation Scale (BBPS), which scores the 3 colonic segments individually (total score range, 0 to 9 with higher scores indicating better preparation quality).

Adequate colonic preparation was achieved in 41 of 49 (84%) colonoscopies. Median total BBPS score was 7 (range, 4 to 9), with median segment scores of 3, 2, and 2 for descending, transverse, and ascending colon, respectively. The ascending colon had significantly lower scores than the descending colon. In 57% of procedures, the indication for colonoscopy was evaluation of chronic enteropathy (combined upper and lower intestinal endoscopy) without specific suspicion of colonic disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sc_a4\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>High-quality bowel preparation for colonoscopy can be achieved without complex or logistically demanding protocols.
