Brief Summary:

The aim of this study is to clarify the factors influencing quality of bowel cleansing for colonoscopy in patients with colorectal cancer surgery and confirm the adequate bowel cleaning method for patients with colorectal cancer surgery. Through this, ultimately in patients with a history of colorectal cancer who have high risk of colorectal cancer, it could be possible to detect cancerous lesions early and increase the survival rate.

This study is based on observational study Subjects are the patients with colorectal cancer surgery who visits the out patients clinic for follow-up colonoscopy The patient's medical records on the basis of information collected at the point of the colonoscopy performed Quality of bowel cleansing is calculated with the Boston bowel preparation scale Patient compliance and satisfaction are measured.

Colonoscopy
patients undergoing colonoscopy after colorectal cancer surgery
Procedure: Colonoscopy



Primary Outcome Measures :
  1. Boston bowel preparation scale (BBPS) [ Time Frame: 1 hour ]
    In this scale, the colon is divided in three segments: the right side (including cecum and ascending colon), the transverse colon (including the flexures) and the left sided colon, which includes the descending colon, sigmoid and rectum. Mucosal view should be scored after cleansing maneuvers like suctioning or washing have been performed. For all three sections cleansing is assessed and given a score ranging from 0 to 3. Therefore, the maximum BBPS score for a perfectly clean colon without any residual liquid is 9 and the minimum BBPS score for an unprepared colon is 0. BBPS score ≥6 in considered an adequate bowel preparation.
