Design outcomes

Primary

MeasureTime frame
Correlation between the colonic contents and the symptoms: correlation between the homology of colonic contents of ascending colon and sigmoid colon, and GSRS score or Bristol scale.

Secondary

MeasureTime frame
1) Correlation between the colonic contents and the environmental factor: correlation between the homology of colonic contents of ascending colon and sigmoid colon, and the medication or last meal or last defecation. 2) Correlation between the luminal diameter of colon and the symptoms: correlation between the maximal diameter of ascending and sigmoid colon, and GSRS score or Bristol scale. 3) Correlation between the luminal diameter of colon and the environmental factor: correlation between the maximal diameter of ascending and sigmoid colon , and the medication or last meal or last defecation.
