this is a cross sectional intervention study to investigate the role of partial hydrolyzed guar gum in high stoma output management among cancer patients with ileostomy. This study hypotheses there is improvement in stoma output in PHGG if compare with control. There are two groups of subjects in this study. Conventional group (CG) will include retrospective historical data (those subjects with post-operative ileostomy) from Jan 2016 to June 2019. Intervention group (PHGG) will be subjects with ileostomy which involves prospective intervention by giving partial hydrolyzed guar gum upon start orally.
