An interventional study of 2L Polyethylene Glycol (PEG) and 4L Polyethylene Glycol (PEG) in Bowel Preparation and Colonoscopy, sponsored by Shandong University. Status unknown at 1 site in China. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2018-12-05.
Sponsored by Shandong University · Not applicable, Interventional, and Prevention
About 30% of patients were reported to suffer inadequate bowel preparation. So, it is desirable to prescribe personalized regimen according to patient's personal characteristics.
Colonoscopy is currently the main approach for detecting mucosal abnormalities in the whole colon. Inadequate bowel preparation is the predominant threaten to the efficacy of colonoscopy.Unfortunately, about 30% of patients were reported to suffer inadequate bowel preparation. In order to improve adequate bowel preparation rate, it is desirable to prescribe personalized regimen according to patient characteristics. We intend to improve adequate bowel preparation rate by deploying tailored bowel preparation strategy. There are many predictive factors of inadequate bowel preparation such as obesity, constipation, abdominal surgery and so on. By recognizing these risk factors of the patients , we can prescribe the patients with higher dose of bowel cleansing regimen to improve bowel preparation quality.

Exclusion Criteria:
Participants are given standard regimen: 2 L Polyethylene Glycol (PEG) regimen.
Drug: 2L Polyethylene Glycol (PEG)
Participants are given personalized regimens for bowel preparation according to the the predictive model( a model which grades patients as low or high risk according to risk factors such as age, body mass index≧ 30 kg/m2, diabetes, constipation, pelvic surgery and tricyclic antidepressants usage). Low risk patients are given standard regimen: 2 L Polyethylene Glycol (PEG) regimen; High risk patients are given standard regimen: 4 L Polyethylene Glycol (PEG) regimen.
Drug: 2L Polyethylene Glycol (PEG) · Drug: 4L Polyethylene Glycol (PEG)
Participants in Group A and Low risk patients in group B are given standard regimen: 2 L Polyethylene Glycol (PEG) regimen
Also known as: Standard
High risk patients in Group B will receive 4 L Polyethylene Glycol (PEG) regimen
