Comparison of polyethylene glycol, sodium phosphate and sennoside for colonoscopy preparation

Background and aim: The efficiency, cecal intubation rate and side effects of colonoscopy preparation with polyethylene glycol (PEG), sodium phosphate and sennosid were compared in this study. Material and Methods: This study was carried out retrospectively by investigating the records of patients undergoing colonoscopy between July 2017 and March 2018.The patients were divided into 3 groups: PEG, sodium phosphate and sennoside group. Patients with dietary incompatibility, renal insufficiency, intestinal obstruction, active infection, active bleeding and who took fewer than 75% of medications were excluded from the study. Bowel preperation was evaluated in 4 groups as excellent, good, moderate and poor. Results: The study population was consisted of 269 persons, 129 female (48%) and 140 male (52%) patients. The average age of the patients was 55 years. When all patients were examined, the excellent cleaning rate was 38%, the good cleaning rate was 17%, the moderate cleaning rate was 26% and the poor cleaning rate was 19%. The adequate cleaning rate was found 52% in the sennoside group, 50% in the sodium phosphate group and 66% in the PEG group. In this study, total cecal intubation rate was 90%. The cecal intubation rate was 100% in the PEG group, 87% in the sennoside group and 85% in the sodium phosphate group. The most common side effects in patients were nausea / vomiting (12%) and abdominal pain (9%). Conclusion: Colonoscopy preparation with PEG is a more effective method than preparation with sennoside and sodium phosphate
