Flexible Sigmoidoscopy: Optimal bowel preparation with enema versus polyethylene glycol

Published by Admin on

Abstract Background: Lower gastrointestinal endoscopy requires adequate bowel preparation. However there is no unanimous recommendation on choice of agent of bowel preparation for the purpose of screening fl exible sigmoidoscopy. Objective: To compare the quality of bowel preparation and patient’s tolerance between Enema (Solution of Glycerin 15% w/v and Sodium Chloride 15%w/v)and Polyethylene glycol for screening fl exible sigmoidoscopy. Methodology: All consecutive patients undergoing screening fl exible sigmoidoscopy were included in the study. We prospectively divided the patients into two groups. Group A received per rectal enema and group B received oral bowel preparation with polyethylene glycol. Adequacy of bowel preparation and patient’s tolerance between two groups was graded. Data were analysed using Microsoft Excel 2010. Results: Results were comparable regarding quality of bowel preparation between two groups (A and B), excellent in 20% and 33.33% and good in 60% and 50% respectively. Almost all patients could tolerate the preparation agent in Group A (n=28). In-group B, eight patients(26.66%) considered the oral preparation agent diffi cult to tolerate and two patients (6%) were unable to complete the preparation. Conclusion: Enema(Solution of Glycerin 15% w/v and Sodium Chloride 15%w/v) andPolyethylene glycol have similar quality of bowel preparation and for screening sigmoidoscopy. Enema is adequate and much easily tolerable compared to polyethylene glycol. Key words: Adequecy; Flexible Sigmoidoscopy; Preparation; Screening; Tolerance
