Brief summary

This case series aims to evaluate the effectiveness and tolerability of Oral Sulfate Solution (OSS) in patients who had previously experienced poor colonoscopy preparation.

Detailed description

This study aims to evaluate the effectiveness of Oral Sodium Sulfate (OSS) in patients who have had poor colon preparation in the past. The study includes patients who had issues during their previous colonoscopy, such as needing extensive washing, inadequate preparation, a recommendation for shorter surveillance intervals, or adequate preparation for larger polyps but not smaller lesions. Poor colon cleansing during a colonoscopy can lead to more prolonged procedures, lower polyp detection rates, and the need for repeat procedures with shorter surveillance intervals. OSS is a low-volume osmotic agent that causes diarrhea and colon cleansing by drawing water into the intestine. Health Canada and the FDA have approved it, and it is given in two 177ml bottles in a split dose. OSS is known for its good effect, ease of use, and tolerability, and it may be a better option than traditional cleansing agents. All participants will receive OSS and instructions for use before their next surveillance colonoscopy. The study will use questionnaires and patient diaries to assess the effectiveness of OSS and patient compliance and tolerability.
