Comparison of three bowel preparations for sigmoidoscopy

Area of Science:

• Gastroenterology
• Colorectal Surgery

Background:

• Rigid sigmoidoscopy is a common procedure for investigating rectal bleeding and diarrhea.
• Adequate bowel preparation is crucial for a clear view during sigmoidoscopy.
• The effectiveness of different bowel preparation methods varies.

Purpose of the Study:

• To compare the efficacy of three lower bowel preparations (Fleet enema, Dulcolax micro-enema, Dulcolax suppository) versus no preparation for rigid sigmoidoscopy.
• To assess the impact of bowel preparation on the clarity of view and maximal insertion length during sigmoidoscopy.

Main Methods:

• A study involving 96 patients undergoing rigid sigmoidoscopy.
• Patients were divided into four groups: three receiving different bowel preparations and one control group with no preparation.
• Outcomes measured included maximal insertion length and clarity of view, with adverse effects also recorded.

Main Results:

• Clarity of view was significantly better with Fleet enema (71%) and Dulcolax micro-enema (68%) compared to Dulcolax suppository (36%) and no preparation (16%).
• Maximal insertion length was similar across all groups.
• No adverse effects or complications were reported for any bowel preparation method or the sigmoidoscopy procedure itself.

Conclusions:

• Bowel preparation, particularly with simple disposable enemas like Fleet enema and Dulcolax micro-enema, significantly improves the quality of sigmoidoscopic examinations.
• These enema preparations are safe and effective, leading to a higher number of satisfactory examinations.
