Comparison of 1-day Clear Liquid Diet and Low-fiber Diet in Bowel Preparation for Colonoscopy

Studies have reported that inadequate bowel preparation reduces the detection of polyps that may have the potential to become cancerous. Unfortunately, however, many participants are unable to comply with bowel cleansing regimens due to strict dietary changes and large amounts of unpleasant laxative solutions that affect their quality of life before the procedure. In addition, participants with insufficient bowel cleansing should repeat similar preparation steps before the next examination. The European Society for Gastrointestinal Endoscopy (ESGE) recommends a polyethylene glycol (PEG) regimen for colonoscopy preparation and low-fiber food intake 24 hours prior to the procedure. In our country, PEG is not used routinely and frequently in terms of cost and lack of SGK payments. 'Sennoside A+B calcium', which is used for colonoscopy preparation in our country, shows its effect by increasing intestinal motility and causes the accumulation of water and electrolytes in the colon lumen. It has security and ease of application. In addition, the fact that it is paid by the Social Security Institution and the price is affordable makes it advantageous in the preparation of colonoscopy. Although there is not enough data for colonoscopy preparation in our country, each clinic determines the duration of the regimen in various ways. The aim of this study is to compare the patient group who used low fiber food for 24 hours before colonoscopy and who had a clear diet for 24 hours before colonoscopy in terms of adequate cleaning during endoscopy in participants who underwent bowel cleansing with 'Sennoside A+B calcium'.
