Evaluating the Effectiveness of Colon Preparation for Endoscopy Using Specialized Clinical Nutrition

Phase IV Prospective Sinle Center Randomised Three-arm Controlled Study Evaluating the Effectiveness of Colon Preparation for Endoscopy Using Specialized Clinical Nutrition

This study is an open, prospective, comparative diagnostic studies aimed at improving the colonoscopy results, by optimizing the way of preparation for endoscopy

Objective: to improve the quality of bowel preparation for endoscopy.

Research objectives:

1. Compare the three methods of colon preparation for endoscopy
2. To develop a rational strategy of preparing patients for endoscopy on the basis of the data obtained.

Inclusion Criteria:

1. Patients older than 18 years with the recommendation to conduct a diagnostic colonoscopy
2. Absence of contraindications to the use of specialized clinical nutrition products
