Real-life risk factors of inadequate procedure prior to colonoscopy in a Turkish population

Colonoscopy is one of the main diagnostic tools for symptoms related to the colon and colorectal cancer screening programs. Inadequate cleansing of colonoscopy leads to misdiagnosis of adenomas. It is recommended to re-evaluate ineffective colonoscopy. It is of utmost importance to predict whether the bowel is clean or not because the procedure is expensive, invasive and time- consuming. This study aimed to identify the risk factors of inadequate bowel preparation. The consecutive two hundred and fifty-three patients who were referred for colonoscopy were enrolled into the study. The demographic and clinical data were obtained using a questionnaire. Only 79.1% of colonoscopy were assessed as adequate. In the univariate analysis; adherence to protocol, older age, consuming high-fiber diet in last two days, number of days of low residue diet, consumed all laxative, consumed 1.5 L water after laxative usage, regular diet for dinner before the day of colonoscopy, amount of water consumed before the day of colonoscopy, amount of water consumed in the morning of the day of colonoscopy, fasting status in the morning of the CD, and were found significantly relevant for adequate bowel preparation. Older age, number of days of low residue diet, consuming high-fiber diet in last two days, regular diet for the dinner before the day of colonoscopy, not Consumed all laxatives were independent risk factors for inadequate colonoscopy. These factors are reversible risk factors except older age. Increasing the adherence to the protocol with education seems to improve the bowel preparation quality.
