The role of diet in bowel cleansing for colonoscopy (results of prospective observation study). Prospective observations study

AIM: to evaluate the impact of dietary compliance in bowel cleansing for colonoscopy on the quality of the procedure.PATIENTS AND METHODS: one thousand patients who scheduled for diagnostic colonoscopy were included in the prospective observation study. The quality of bowel preparation was assessed using the Boston scale. Neoplasms were detected and endoscopically evaluated. The optical verification of tumors was used to calculate the indicators of identified adenomas and polyps (ADR and PDR).RESULTS: the quality of bowel cleansing by the Boston Scale was 6 (6; 8) points. One hundred eight (19.8%) patients did not follow the recommended diet. Poor preparation, which did not allow a total colonoscopy was found in 91 (9,1%) cases. The ADR was 37.4%, PDR — 43.4%. Logistic regression analysis showed that the noncompliance for diet recommendation was the only one significantly negative factor associated whit inadequate bowel cleansing.CONCLUSION: the leading factor worsening the quality of bowel cleansing was non-compliance with the prescribed diet before the colonoscopy.
